가교제인 trimethylol propane(TMP)의 함량변화에 따라 다양한 폴리우레탄(PU) 평판을 제작하였다. DMA 측정을 통하여 TMP 함량에 따라서 PU의 $T_g$는 34.8 $^{circ}C$에서 49.9 $^{circ}C$로 증가를 확인하였다. TMP의 함량이 4%에서 12%까지 증가함에 따라 탄성률은 322 MPa에서 423 MPa로 증가하였고, 인장강도는 10.6 MPa에서 14.8 MPa로 다소 증가하였으며, 신율은 62.8%에서 49%로 감소하였다. 음향특성의 경우, TMP의 함량이 증가함에 따라 가교 정도가 높아지며, 음속은 증가하였으나 음향감쇠계수는 감소하였다. 제작한 PU... -

right lateral recumbent position and an acoustic window was created in the fourth or fifth intercostal spaces. If images of the aorta were obtained in the right parasternal long-axis left ventricular outflow view, then the area anterior to the left ventricular outflow tract and left interventricular sulcus were examined using 2D imaging in combination with color flow mapping. Images of the... This study was conducted to evaluate the usefulness of coronary arterial profiles from normal dogs (11 animals) and canines (six dogs) with experimental myocardial infarction (MI) induced by ligation of the left coronary artery (LCA). Blood velocity of the LCA and right coronary artery (RCA) were evaluated following transthoracic pulsed-wave Doppler echocardiography. The LCA was observed as an infundibular shape, located adjacent to the sinus of Valsalva. The RCA appeared as a tubular structure... -

imaging system (Sonoace 9900; Medison, Korea) were used. The sagittal plane of the right kidney was imaged. The right kidney was selected for analysis because this kidney provided a better acoustic window in the micropigs. Before imaging, the hair was clipped and acoustic gel was applied for acoustic coupling. The transducer was carefully held by hand and maintained in the location of the... Contrast-enhanced ultrasound is one of method for evaluating renal perfusion. The purpose of this project was to assess perfusion patterns and dynamics in normal micropig kidney using ultrasonographic contrast media. Eight young healthy micropigs were included in this study. Micropigs were anesthetized with propofol and received an intravenous bolus of microbubble contrast media through an ear vein. Time/mean pixel value (MPV) curves were generated for selected regions in the right renal cortex... -

a craniotomy or open fontanelle as an acoustic window in adult dogs [16] and neonates [17]. The B-mode ultrasonographic characteristics of both the normal and hydrocephalic canine brain have been described [16,33]. Although numerous cerebral vessels have been mapped and their TCD parameters characterized using TCD in human, few veterinary reports have evaluated TCD of the canine brain, even in a... normal dogs, respectively. There was no significant difference of RI between male and female; between fontanelle window and temporal window. Reproducibility of RI measurements between intraobserver and interobserver were relatively high. The RI of RCA and CCA were significantly increased 15 minutes after mannitol administration (p < 0.01) and returned to baseline values by 30 minutes, but it did not significantly change after furosemide and saline administration. The results suggest that TCD is... -

and then the mode was switched to the pulsed Doppler mode. The sample volume cursor was located in the small intestinal lumen through the acoustic window of the spleen. The number of peristaltic contractions was recorded three times over a one-minute time period and the average number of contraction was then calculated. The ultrasound scans were measured at 0, 1, 3, 6, 9, 12, and 24 hour after a... The purpose of this study was to verify whether small intestinal peristalsis could be observed and quantitatively assessed using pulsed-Doppler ultrasound. Pulsed-Doppler ultrasound was used to evaluate small intestinal peristalsis after a meal in ten normal dogs and ten sedated dogs. The small intestinal peristalses were measured 0, 1, 3, 6, 9, 12, and 24 hours after a 24-hour fast and after feeding. The number of small intestinal peristalsis were 0.133/min, 0.100/min, 0.033/min, 0.167/min,... -

ULX-induced abnomalities of the vestibular function can... To search the correlations between electrical activity and c-Fos expression in the process of vestibular compensation, we examined the changes of those two parameters in the medial vestibular nuclei (MVN) of unilaterally labyrinthectomized (ULX) rats. Spontaneous nystagmus with fast component toward the intact side disappeared gradually within 48 hours. Fourty eight hours after ULX, directional preponderance of the eye movement induced by sinusoidal rotation of the whole body which represents... -
