Three cases of extrahepatic bile duct disorder were presented. Two cases, a dog and a cat, were related to the obstruction of the extrhepatic bile duct, the other dog was affected with the gall ...bladder rupture. The clinical signs included anorexia, abdominal distension and vomiting. The laboratory test represented increased hepatic enzymes. On the radiography, hepatomegaly was seen in the obstructive cases, and ascites could be seen in the ruptured case. On the Ultrasonography, dilated gall bladder and extrahepatic bile duct were found in the obstructive cases, and there were ascites, indistinct gall bladder wall, dilation of gall bladder and extrabiliary tract, increased mesenteric echogenicity in the ruptured case. All presented were taken medication, surgical foreign material removal, or cholecystectomy showed complete recovery.
The purpose of this paper was to compare the clinical efficacy of iopamidol and iopromide, iohexol nonionic contrast media in terms of their image quality in Beagle dogs with hepatic CT angiography ...and their application in veterinary clinics. With 9 Beagle dogs, contrast media of iopamidol (pamiray-$300^(R)$) and iopromide (ultravist-$300^(R)$, iohexol (omnipaque-$300^(R)$) were induced intravenously (600 mg I/kg, BW) and CT angiography was done under general anesthesia. CT scan included scout, pre-contrast and cine examinations. During CT angiography, peak HU (Hounsfield unit) and peak time were examined on each site (ROI; region of interest) of the aorta, caudal vena cava, potral vein and liver parenchyma. Any side effects were also examined. After experiments, it was found that there were no significant changes of HU and maximal enhancing time of each ROIs of aorta, caudal vena cava, portal vein and liver parenchyma between these contrast media. And any side effects were not noted. So it is concluded that iopamidol has similiar contrast enhancement like as iopromide and iohexol in hepatic angiography and and it is thought to be useful for evaluation of the abdominal organs by CT scan in veterinary clinics.
Amorphization and crystallization behavior of an equiatomic Ti-Ni alloy have been investigated by means of differential scanning calorimetry, X-ray diffraction, optical microscopy and transmission ...electron microscopy. Amorphous phases were induced by cold working, and their morphologies changed from domain like shape to band shape with increasing the amount of cold working. Volume fraction of amorphous phase increased from 17 to 43 % with increasing working ratio from 30 to 70 %. With increasing the amount of cold rolling from 30 to 70 %, the crystallization temperature increased from 552 to 539 K and enthalpy changes associated with crystallization increased from 170 to 447 J/mol. The average grain size of the 40 % cold rolled alloy increased from 27 to 80 nm with increasing annealing temperature from 573 to 673 K.
AIM：To investigate the diagnostic accuracy of hepatobiliary scintigraphy（HBS） in detecting biliary strictures in living donor liver transplantation（LDLT） patients.METHODS：We retrospectively reviewed ...104 adult LDLT recipients of the right hepatic lobe with duct-toduct anastomosis,who underwent HBS and cholangiography.The HBS results were categorized as normal,parenchymal dysfunction,biliary obstruction,or bile leakage without re-interpretation.The presence of biliary strictures was determined by percutaneous cholangiography or endoscopic retrograde cholangiopancreatography（ERCP）.RESULTS：In 89 patients with biliary strictures,HBS showed biliary obstruction in 50 and no obstruction in 39,for a sensitivity of 56.2%.Of 15 patients with no biliary strictures,HBS showed no obstruction in 11,for a specificity of 73.3%.The positive predictive value（PPV） was 92.6%（50/54） and the negative predictive value（NPV） was 22%（11/50）.We also analyzed the diagnostic accuracy of the change in bile duct size.The sensitivity,NPV,specificity,and PPV were 65.2%,27.9%,80% and 95%,respectively.CONCLUSION：The absence of biliary obstruction on HBS is not reliable.Thus,when post-LDLT biliary strictures are suspected,early ERCP may be considered.
We describe two cases of a macular hole (MH) which had divergent manifestations and clinical courses following implantation of an Implantable Collamer Lens (ICL) in two high myopic patients. The ...onset of symptoms and shape of the holes, which were observed by optical coherence tomography and fundoscopy, and prognosis of the visual acuity after the surgery of each patient, were quite different. In the first patient, the symptom was an acute onset. Fundoscopy showed a cuneiform-shaped hole with internal limiting membrane defect around the hole. The prognosis after the surgery was very poor, and the best corrected visual acuity was 0.08 after complete anatomical closure. In another patient, the MH showed insidious progression with disease-free interval from ICL implantation to MH onset. After the surgery, the best corrected visual acuity was recovered to 1.0.
