    <p>大動脈弁狭窄症の治療法として経カテーテル大動脈弁留置術(TAVI)が普及しつつあり,弁周囲漏れ流れ(PVL)での血栓形成が指摘されているものの,その詳しい形成機構はわかっていない.著者らは人工弁での逆流をモデル化した形状(TAVI PVLモデル)で,血栓形成の可視化実験を行い,この隙間があることで血栓形成が促進されること,後流となる低せん断速度領域に血栓が形成することを明らかにしているが,せん断速度場の変化による血栓形成については検討されていない.そこで本研究では,形状の異なるTAVI PVLモデルによる可視化実験やCFDを用いた流動解析から,せん断速度場等の変化が,血栓の形成位置,形成速度,形成時間などに与える影響を調べた.実験では,隙間を与えた透明アクリルのオリフィスパイプ流れの中で,レーザーシートを用いた血栓の可視化実験を行い,その光量分布から高濃度の血栓生成分布を求めて,血栓生成面積やその時間変化から血栓生成速度を算出した.その結果,(1)血栓形成時間の計測から,隙間部から血栓形成が始まっていること,(2)血栓形成速度については,形状変化によるせん断速度の影響を受けつつ,隙間の変化によっても変化すること,(3)CFD解析から軸対称の形状ではあるものの,流れの3次元性による効果による後流渦の変化などから形成位置に影響することが示唆された.</p>

  • Measurement of calcium ion concentrations on neutrophils in elucidating the mechanism of neutrophil propulsion for immunotherapy

    OBANA Rintaro, TAMAGAWA Masaaki

    The purpose of this study is to elucidate the neutrophil propulsion mechanism by cytokine. It is generally known that the interactions between cytokines and receptors on the neutrophil surface are related to signaling by calcium ions (Ca<sup>2+</sup>). In this study, to clarify the effect of calcium ion concentration on the neutrophil propulsion mechanism, observation experiments with a microscopy are conducted. The time history of calcium ion concentration is obtained by Fura-2. As a result, it was found that stimulus by cytokines reduces calcium ion concentrations on the neutrophil surface. It was also found that calcium ions on the surface are consumed in
    dead neutrophils, but it doesn’t move. It is concluded that calcium ions have an important role in signal transduction and are consumed by cytokine stimulus.

  • The Examination to Explain the Neutrophil Propulsion Mechanism by the Rotational Motion and Its Period

    The purpose of this research is to elucidate the neutrophil propulsion mechanism by cytokine. In this study, to investigate the relationship between the velocity and the rotation or its period, observation experiments with a microscopy was conducted. The period of rotation was obtained from the time history of the concentration gradient by frequency analysis. As a result, it was found that the velocity is high when the period of rotation is short. It is concluded that the neutrophil’s rotation is an important role in the neutrophil's propulsion mechanism.

    Computational Fluid Dynamics facilitates in the quantitative analysis of haemodynamic processes of in vivo cardiovascular systems. The objective of the present study is to examine the effects of different branching angles of diseased renal arteries with respect to the abdominal aorta on its flow characteristics. Secondly, simulation of normal renal arteries at similar branching angles were also done as a baseline for comparison to comprehend if geometry played a role in the endothelial proliferation in renal artery stenosis. Idealistic renal artery models generated from the digital image of computerized tomography scan were used, with bifurcation angles at the junction ranging from 30° to 90° at successive intervals of 15°. Virtual stenosis of a degree below and above 80% by diameter were generated on the right and left renal artery respectively. The models were discretized using a hybrid polyhedral mesh. Parameters such as time-averaged velocity, time-averaged wall shear stress, pressure difference and fractional flow reserve were used to analyse the flow characteristics. Stenosed renal arteries with higher angulation was found to have larger flow recirculation zones, higher pressure gradient near the Ostia and was observed to experience greater amounts of shear stress at the region of stenosis. For the same degree of stenosis (above 80%), the blockage tended to increase from 18% to 25%, as the angle increased. The effect of angulation was observed to alter the flow characteristics significantly in the stenosed arteries. Critically stenosed (above 80%) renal arteries at a bifurcation angle above 45° showed signs of ischemia.

    Paravalvular Leakage (PVL) has been recognized as one of the most dangerous complications in relation to Transcathether Aortic Valve Implantation (TAVI) activities. However, data available in the literature about Fluid Structure Interaction (FSI) for this specific problem are relatively limited. In the present study, the fluid and structure responses of the hemodynamics along the patient aorta model and the aortic wall deformation are studied with the aid of numerical simulation taking into account PVL and 100% TAVI valve opening. In particular, the aorta without valve (AWoV) is assumed as the normal condition, whereas an aorta with TAVI 26 mm for 100% Geometrical Orifice Area (GOA) is considered as the patient aorta with PVL complication. A 3D patient-specific aorta model is elaborated using the MIMICS software. Implantation of the identical TAVI valve of Edward SAPIEN XT 26 (Edwards Lifes ciences, Irvine, California) is considered. An undersized 26 mm TAVI valve with 100% valve opening is selected to mimic the presence of PVL at the aortic annulus. The present research indicates that the existence of PVL can increase the blood velocity, pressure drop and WSS in comparison to normal conditions, thereby paving the way to the development of recirculation flow, thrombus formation, aorta wall collapse, aortic rupture and damage of endothelium.

    <p>In the immunological systems, the neutrophil’s motion is considered to be propelled by concentration gradient of cytokine. However, the mechanism of propulsion has not been elucidated yet in the previous researches. Assuming that neutrophil moves by the concentration Marangoni effect, concentration gradient of cytokine on the surrounding fluid and neutrophil membrane is experimentally examined. In our previous investigations, it was found that the concentration gradient on the neutrophil membrane repeats positive and negative <sup>(1)</sup>. Moreover, it was found that a neutrophil has pseudopods near the inner wall surface of the blood vessel <sup>(2)</sup>. In this study, the effect of pseudopods is investigated.</p><p>As for the experimental methods, the neutrophils are observed by a microscope. Concentration gradient of surrounding fluid is generated by inserting cytokine solution into the neutrophil dispersion. Using CCD camera, the neutrophil’s propulsion and concentration distribution are obtained by measuring emission intensity of fluorescent substance FITC. Based on the neutrophil velocity obtained from this observation, the effects of pseudopods on the propulsion mechanism are evaluated. The result shows that the propulsion mechanism of the neutrophils depends on the cytokine concentration with or without pseudopods. It is also found that neutrophils with pseudopods move slower than the neutrophils without pseudopods.</p>

    In this study, to investigate the phenomenon that neutrophils generate pseudopods near the wall, the distance between the neutrophils and the wall is measured. As the result, it is found that the neutrophil velocity decreased near the wall. The geometrical characteristics of the neutrophils are asymmetrical at a distance from the wall, but no extreme peaks such as pseudopods appeared on the membrane. In addition, the relationship between the shape of neutrophils and the propulsion mechanism is investigated by calculating the velocity of neutrophil movement and the concentration gradient on the membrane of neutrophils stimulated by shock waves, evaluating the membrane function of neutrophils, and comparing it with the geometric characteristics. The results show that shock wave stimulation improved the membrane function of neutrophils. Besides, it is found that the arithmetic mean roughness and root mean square roughness of the neutrophils decrease for the shock wave stimulus. The changes in skewness and kurtosis indicated that the surface roughness of the neutrophil membrane increased. In the future, it will be investigated that the further factors that affect the propulsion of neutrophils and the driving principle in detail.

It was found that the maximum penetration force is increasing with penetration angle, and the duration time for penetration is also increasing due to the increment of the angle. As for the contact shear stress analysis on the vein wall, Ansys Mechanical was used to obtain the maximum stress. It was found that the maximum shear stress is approximately 100kPa when the force to move the PIVC is 2N. It is concluded that there is a risk of thrombus formation as the level of the shear stress is several kPa due to the prediction of the shear stress by FEM analysis.</i><tt><i> </i></tt></p>

    <p><i>The goals of this study are to examine the propulsion of neutrophils which move in water in the direction of high concentration of the cytokine and to apply it to DDS. Assuming that neutrophils move by the concentration Marangoni effect, we experimentally examined changes of cytokine concentration on the surrounding fluid and neutrophil membrane. But detailed propulsion mechanism is unknown. Especially, the effects of pseudopods which are used when neutrophils move on the inner wall of blood vessels on the underwater propulsion, and the effects of living neutrophils and dead ones on membrane properties are still unknown. Then, in this study, the observation using the microscope was carried out, and the moving speed of neutrophils and the concentration gradient on the membrane was quantified. Besides, the effect of the membrane properties on the propulsion mechanism was investigated by examining the difference of these values living status, dead status, with pseudopods and without pseudopods. The results show that there is a large difference of cytokine concentration on membrane, in case of pseudopods. It was concluded that both neutrophil’s velocity and concentration gradient on the membrane are greatly influenced by living status and dead status. </i></p>

    <p>This paper describes prediction method of thrombus formation at the wall on orifice flows by using particle method (DPD) with aggregation of platelets and finite difference method (FDM) for transport process of concentration. By the hybrid model of the particle method and FDM, the prediction of thrombus formation rate was compared with the experimental data conducted in the previous investigation. In this method, the total number of particles in the DPD can be decreased by using novel technique of virtual particle method. As a result, the effects of aggregation between the platelet in the CFD are not large comparing with the data in the previous experiments. It was also found that there is a possibility to improve the accuracy by modifying the model of virtual particle method.</p>

In our previous investigations, there are oscillation of concentration gradient on the membrane of neutrophil when it is moving toward the direction of higher concentration. It is necessary to find out the reason why the neutrophil is continuing to move under the concentration gradient. In this paper, the mathematical model of driving force by surface tension gradient. To establish the model, it is assumed that the surface tension depends on the concentration and temperature. It is found that the velocity by this oscillation depend on the amplitude of concentration gradient and period of oscillation. In this investigation, the mathematical model of driving force by oscillation of concentration gradient was established, and it will be confirmed by the experiment of microscopic observation of concentration gradient.</i></p>

    <p><i>This paper describes the relation between relative position of peripheral intravenous catheter (PIVC)in vein and thrombus generation around it. In this study, it is assumed that the contact of catheter on the vein wall causes thrombus formation due to change of flow filed</i>. <i>In the first step, the thrombus formation process was visualized by using a vascular model. As a result, a thrombus was found around a catheter at 240 s in case of 0 ml/h flow of the intravenous feeding, but in case of 20ml / h it takes 480 s. Then the flow rate of PIVC was changed from 20 ml / h to 0ml / h with the stepwise reduction. It was found that thrombus was increasing on the catheter circumference. In the next step, in order to investigate the effects of flow rate of PIVC on the flow field, CFD analysis around the catheter in the infantile vein was done. The results show that there are low shear rate regions, low velocity regions, and long retention time region near the area of catheter’s contact. By using the proposed evaluation value of thrombus formation with strain rate and retention time. It was concluded that feeding flow rate of PIVC is sensitive to thrombus formation rate, and the high flow rate of PIVC has low risk for thrombus formation.</i><i> </i></p>

    <p>This paper describes a regenerating system of living tissue combining culture promotion and capsule destruction by shock wave, and the development of the system. In this system, shock wave are applied to microcapsules containing bubbles for Drug Delivery System (DDS) to simultaneously stimulate cells and destroy capsules. The capsule have an important role as a medium for cell culture in regenerative medical. In this study, underwater shock wave is generated using short-time pulse laser with femtosecond for stimulating cells. The pressure of shock wave was measured at the positions by the pressure sensor. These positions are distances 0.3mm, 0.4mm, and 0.5mm from the focal point. An approximate expression was obtained from the peak pressure measured at each position, and the pressure at the focal area was obtained. As a result, the pressure at the focal area was estimated to be 2.4MPa at the 1Hz and 2.2MPa at the 100Hz.</p>

    <p>PVL (Paravalvular Leak) is blood leak from the gap between artificial valve and aorta, and it is considered to be one of thrombosis risks in TAVI (Transcatheter Aortic Valve Implantation). In our previous study, thrombus formation was visualized at the cross-section of PVL models with large or small gaps. And it was found that thrombus formation rate is high on the large gap. In this study, thrombus formation was visualized on the inner surface of the PVL models, and the type of thrombus (red thrombus and white thrombus) was recognized by image processing. As a result, it was found that the white thrombus was mainly generated around the PVL models regardless of the gap size. It was suggested that the flow around the PVL models is high shear flow, therefore white thrombus is generated around the PVL models by platelet activation. In addition, it was also found that the white thrombus was rapidly generated around the large gap. This result has same trend as the previous study, and it was expected that more platelets are activated in the large gap.</p>

    <p>This paper describes the relation between relative position of peripheral intravenous catheter in vein and thrombus generation around it. In this study, it is assumed that the contact of catheter on the vein wall causes thrombus formation due to change of flow filed. First of all, the thrombus formation in the vein model, which is made of silicone tube, were observed by CCD camera. It was found that there are some cases of catheter’s contacts to the tube wall when the thrombus occurs. To investigate the flow field of the flow, CFD analysis around the catheter in the infantile vein was done. The results show that there are low shear rate regions, low velocity regions, and long retention time region near the area of catheter’s contact. It was concluded that the relative position of catheter in the vein may cause the thrombus formation due to infant’s motion during drip.<i> </i></p>

    <p>This paper proposes a culture tissues regeneration system combining culture promotion and capsule destruction by shock wave, and describes the development of the system. In this system, shock wave are applied to microcapsules containing bubbles for DDS to simultaneously stimulate cells and destroy capsules. The capsule have an important role as a medium for cell culture in regenerative medicine. In this study, shock wave is generated in water using short-time laser with femtosecond as the purpose of stimulating cells. Particle motion around the focal point was observed by image processing. And the pressure at the focal area was also obtained by solving motion equation of particle. As a result, the pressure received by the particle at the position of 48.9μm from the focal point was 192Pa, and the pressure in the focal area was predicted to be 0.29MPa.</p>

    <p>Platelet aggregation and separation are important processes in thrombus formation. In our previous investigations, dissipative particle dynamics(DPD) has been used to simulate thrombus formation on orifice flow. In DPD, particle means platelet. However, the number of particles is vast when platelet concentration is the same as the blood. In this investigation, virtual particle model is used to decrease the number of particles. In our virtual particle model, several platelets are considered to be one virtual particle. In order to focus on the aggregation number in cases of different numbers of virtual particles, new variable of relative aggregation number is used. It is found that the relative aggregation numbers are almost the same although numbers of particles are different. It means that the probabilities of platelet aggregation are almost the same. So it is concluded that the aggregation number can be computed by using the model of virtual particle.</p>

    <p>Catheter is commonly used medical equipment inserted into the small peripheral intravenous (PIV) for infusing fluids, drug and transfusions. In case of the treatment, thrombus formation sometimes occurs at the catheter outlet. The reasons are considered to be infants’ crying and motion of catheter. In this investigation, effects of the catheter position, venous flow and catheter flow on the thrombus formation are examined in the CFD model composed of the catheter and vein. By using the result, the probability of thrombus formation is evaluated as the product of strain rate and residence time near the wall. It was found that there is high probability area of thrombus formation near the catheter outlet.</p>

    <p>TAVI (Transcatheter Aortic Valve Implantation) is a minimally invasive treatment for Aortic Stenosis. Although when PVL (Paravalvular Leaks) occurred after surgery, life prognosis worsens. In this research, we made a PVL model with clearance around the orifice and compare visualization of thrombus formation on PVL flow visualized by optical system and flow field is also analyzed by CFD. Experimental result showed that PVL model thrombus formation depend on the clearance size. That is, thrombus formation in large leak model start around the leakage, whereas thrombus formation in small leak model start around the orifice. According to the CFD result, it was found that vortex and contraction existed in the flow field. It turned out that the vortex became smaller as the leakage became larger, but the contraction flow became larger as the leakage increased. Next, the difference in thrombus formation rate (Rs) near the wall compared with the clearance size. As a result, it was found that the leakage is large, the Rs increase. It was suggested that small wake by large leakage flow affected thrombus formation.</p>

In this study, it is assumed that the difference of pressure or flow rate between normal and infantile crying causes thrombus formation. First of all, the blood pressure of infant are measured, and the difference of blood pressure between normal status and infantile crying. It was found that the blood pressure increases according to the infantile crying, and the difference of blood is approximately 20 mmHg. To investigate the flow field of the flow, CFD analysis around the indwelling needle of drip injection (catheter) in the infantile vein was done. The results show that the increasing flow rate or velocity make the accumulation of particle around the inlet of the catheter.<b> </b></p>

    <p>This investigation describes the hybrid method to combine concentration transport process of species by FDM and platelet aggregation by DPD. Computational objects are 5 types of pipe flows through an orifice, which were same geometries in our previous observation experiments of thrombus formation. Using the velocities and pressures in case of turbulent flow by N.S. Equations, the concentrations of species with chemical reaction are computed by FDM. In our newly proposed hybrid model, DPD is applied to express the aggregation process of platelet on the wall. By adding the DPD model with aggregation, number of aggregated and activated platelets was evaluated. By using probability of deposed platelets on the wall, the total number history of activated and aggregated platelets was obtained. The rate of aggregated platelets was compared with our previous experiments of thrombus formation rate.</p>

    <p>TAVI (Transcatheter Aortic Valve Implanation) is one of treatments for Aortic Stenosis.Although TAVI has been established as a treatment less burdensome to patients, there is the fact that when PVL (Paravalver Leaks) occurs after surgery, life prognosis worsens. In the CFD simulation, it is shown that when a prosthetic valve smaller than the aortic inner diameter is placed, PVL is generated, which greatly affects mass flow loss and blood flow recirculation, causing thrombosis and aortic wall deformity . However, experiments using actual artificial valves have not yet been carried out satisfactorily. In this study, as a first step to investigate the cause of PVL, a prosthetic valve was placed in a simple cylinder tube, so that PVL does not occur, and analyze the flow around the prosthetic valve. We used the PIV system in the experiment. By this experiment, when the prosthetic valve is indwelled so as not to have a gap with the wall surface, it is understood that flow stagnation is occurring at the posterior part of the prosthetic valve, and it is considered that stagnation of this flow can cause thrombus formation. Through this experiment, We found the characteristics of the flow behind the prosthetic valve, and it became a foothold for clarification of PVL.</p>

    <p>This paper describes development of regenerative medical system using microcapsules including gas by shock waves. The newly proposed system has two features. One is culture mode by pressure wave, and the other is rupture mode by interactions between shock waves and bubbles in microcapsules. Especially, the worked shock waves by using short-time laser with femto seconds will be generated in the water in this investigation. It was found that the optical system was established correctly by checking laser power. The control of power, duration and waves were discussed to improve the pressure waves in water. The result showed that (1) optical system was established by confirming maximum pressure at the focal point, (2) maximum pressure is 0.36MPa, and the pressure decays with distance from the focal point.</p>

    A new method of wastewater treatment using electric discharge in the water cavitation field formed by a large number of micro bubbles generated by high-speed water flow is proposed in this paper. Indigo carmine solution, which is a type of dye, with a concentration of 9 mg/liter was used as the specimen solution for demonstration of water treatment. The total volume of solution and the average speed of solution in the cavitation field were 20 liters and about 7.4 m/s, respectively. An absorbance decrease rate of 96% was obtained in 50 min of treatment time at the electrode distance of 2 mm and discharge power of 16 W. It was also found that the efficiency of decolorization was improved by changing the electrode location. © 2013 Wiley Periodicals, Inc.

    By the fall experiment using the dummy doll of the vertical posture, it has been suggested that the head rotates with a heel as a pivot point and free-falls. The purpose of this study is to examine whether each physical part of the dummy doll of various posture is modeled as a rotational, free-fall movement. The setting conditions of the experiment were fall posture, fall direction, kind of protective equipment, and with or without protective equipment. As a result, it was suggested each physical part was modeled as a rotational, free fall movement. And head injury criteria (HIC) almost supported the tendency of the previous study even if it was not vertical posture.

    Living assistance equipments are strongly needed not only a machine centered safety but also the concepts of human centered safety. A various structural & functional criteria should be based on the knowledge of anatomical & physiological characteristics. A risk has commonly given by relative and comparative expressions, whose styles are various survival or death ratio. The choice of risk are judged from the weight -ratio of benefit and disbenefit for group members or each person, and the death ratio for the risk is almost reduced to below 10^<-5>〜10^<-6>, and final judgments of accept or rejects for the criteria (level acceptable) depend on consciousness of social members. The ISS3 of TRISS mentions that the injured persons, being in death ratio 0.0035, are estimated as lifelong death ratio 5.8%, an average duration of life 2.7 years and an annual death rate 0.0007, if our life span is about 90 years and an operating time of those equipments reaches 4 hours every day. Those values are much smaller than ratio of automobiles or that of accidental death, and are same levels of the death rate of natural calamity. The TRISS has some defects: one of them is no considered effects of multiple traumas in our same region of our body, and the others are taking no accounts of an effect of aging for seniors. However, an estimation of TRISS becomes similar to that of ASCOT in the case of slight or severe injury, and accompanied with single trauma in the same region.

    This paper describes the development of ballast water treatment systems using interaction of bubbles, shock waves and discharges. In this development, we have cavitation flows during nozzle and diffuser part (reactor) and discharge in this cavitation area. The aim of this investigation is to satisfy the IMO standard for ballast water treatment by using our special cavitation discharge water treatment system, and to modify the geometry of reactor part in the circuit by using simple measurement method of the bubble density and diameter. In this paper, it is concluded that (1) the disintegration rate of plankton (more than 50 μm) by using cavitation discharge is satisfied in IMO standard (D-2), (2) by simple measurement method, the result of bubble density distribution in the reactor almost agrees with the position of electro node for discharge optimized with efficiency in the previous experiment. © 2012 The Japan Society of Mechanical Engineers.

    This paper describes the prediction of index of thrombus formation in shear blood flow by computational fluid dynamics (CFD) with Lattice Boltzmann Method (LBM), applying to backward facing flow, which is simple model of shear flow in the rotary blood pumps and complicated geometry of medical fluid devices. Assuming that the blood flow is multiphase flow composed of blood plasma and solid protein, the effects of surface tension and adhesion force to the wall are added to LBM computation. It is found that the thrombus formation occurs just after the reattachment point and behind the step. These results correspond to our previous observation results. To predict thrombus formation in every case of blood flow, effects of threshold level of physical parameters such as shear rate, adhesion force (effective distance from the wall) are estimated.

    This paper describes prototype of microcapsule including a bubble for Shock Wave Drug Delivery Systems and evaluation of their mechanical properties. Microcapsules are generated by dropping mixed solution of Sodium Alginate and Polyvinyl Alcohol (PVA) into Calcium Chloride solution (CaCl2) Young's modulus are estimated by an aspiration experiment and its numerical analysis. Liquid and gas are injected into the microcapsules on micromanipulation system by hand. The result showed that microcapsules generated by low concentration of Sodium Alginate, PVA, and CaCl2 are able to be injected by micropipette and to make the microcapsule including a bubble. Furthermore, we found the existence of threshold value of apparent Young's modulus between able or disable of injection on the assumption of visco elasticity of microcapsule shell.

    This paper describes a numerical prediction method for hemolysis properties in orifice-pipe blood flows. In this study, several types of orifice-pipe flows by using two turbulence models are computed, which are ( 1 ) standard low Reynolds number k-ε model and (2 ) the k-ε model with partly patched Launder-Kato model (LK-Zonal model) to improve computational accuracy. These predicted flows are compared with (a) measuring pressure loss and (b) measuring reattachment length, and it is found that the flow using LK-Zonal model has good agreement with experiments. Then the hemolysis properties are estimated from the predicted flows. The results are 1) computational accuracy of orifice-pipe flow is improved by using LK-Zonal model, 2) accuracy of predicted hemolysis is also improved especially in orifice-pipe that have long contracted part.

The new methods of examining the inertia of red blood cells (particle) on particle path are discussed using computational fluid dynamics (CFD). In this method, the particles are moved by Stokes drag including effects of difference between density of plasma and internal liquid in the blood. The results of analysis by this method show that (1) the diameter of the particle (red blood cell) that means inertia of the cells, (2) the configuration of the objective wall boundary are important factor. These results also show that if the inertia and the contact with the wall are considered, the precision of the prediction of the hemolysis properties will be progressed.

    This paper describes a method of predicting hemolysis induced by turbulent shear stress (Reynolds stress) in simplified orifice pipe flow. In a centrifugal blood pump, serious hemolysis occurs at the impeller or the casing edge. The turbulent shear stress computed using a low-Reynolds number k-ε model near the edge proves to be several hundred times the laminar shear stress (molecular shear stress). The peak turbulent shear stress is about 2 500 Pa, which is much larger than that obtained from a conventional hemolysis test using viscometer. Then the threshold of turbulent shear stress for hemolysis is determined by comparing with that obtained in hemolysis experiments of pipe-orifice blood flow.
