Ten male rhesus monkeys, each weighing 3.5 kg, were divided into four groups of 3, 3, 2, and 2, and were fed daily with 100 g pelleted food containing 300, 30, 3, and 0 ppm cadmium, respectively. Urine samples were collected every 2 weeks and blood samples every 4 weeks. One monkey each of the 300 and 30 ppm groups was autopsied for pathological examination(More)
Serum alpha-fetoprotein (AFP) concentrations were measured before and after surgical removal of tumor masses in four dogs with hepatocellular carcinoma (HCC). Localization of AFP was also examined immunohistochemically in tumor tissues. In three cases, the serum AFP concentration was 10 to 20 times higher than that of normal dogs. One to two months after(More)
The effects of whole blood storage time on platelet aggregation and on post-transfusion platelet survival time were assessed in dogs. Citrate phosphate dextrose adenine-1 (CPDA-1) was used as a blood cell preservative. Storage time dependent decay of platelet aggregability was assessed. Platelet aggregation responses to collagen and ADP were maintained for(More)
The radioimmunoassay (RIA) for trypsin-like immunoreactivity (TLI) is one of the most sensitive and specific tests for detecting exocrine pancreatic insufficiency (EPI). An abnormally low serum TLI concentration (<2.5 ng/ml) indicates end-stage EPI. Although RIA methods can be used to detect canine serum TLI, these procedures are beyond the capabilities of(More)
Rumen ciliate composition of river-type water buffalo and goat in Nepal was surveyed. As the result of survey, 13 genera representing 52 species and 20 formae of the ciliates were identified. Of them 13 genera with 44 species and 9 formae were found from the water buffalo and 8 genera with 21 species and 12 formae from the goat. The present paper shows the(More)
Characteristics of the signal transduction in Platelet activating factor (PAF)-activated platelets and effects of anti-platelet agents on this response were investigated in vitro for potential therapeutic applications in canine endotoxemia. Blockade of the PAF receptor by a specific blocker has the strongest inhibitive effect on the PAF-induced platelet(More)
The effect of treatment for anestrus in buffaloes with a PGF2α or GnRH injection and vitamin-mineral (Vit-M) supplementation for 1 to 2 months and some factors influencing the treatment effect were studied. In anestrus buffaloes with CL, an injection of PGF2α tended to show higher estrus detection and pregnancy rates within 17 days after treatment than(More)
