To develop an adequate animal model for atherosclerosis in large vessels of patients with diabetes, i.e. diabetic macroangiopathy, we induced diabetes in APA hamsters with a single injection of streptozotocin (SZ) and examined the aorta histopathologically and immunohistochemically. As a result, hyperglycemia and hyperlipidemia were continuously observed(More)
To clarify how Syrian hamsters of the APA strain (APA hamsters) keep a diabetic condition for a long period, the functional and histochemical changes in the pancreatic islets of diabetic APA hamsters were examined. By glucose tolerance test, no glucose-induced insulin secretion was seen in the diabetic APA hamsters. By immunohistochemistry, it was revealed(More)
OBJECTIVE To evaluate results of centrosome hyperamplification in naturally developing tumors of dogs. SAMPLE POPULATION Tumor specimens from 9 dogs with tumors (rhabdomyosarcoma, osteosarcoma, chondrosarcoma, myxosarcoma, and mammary gland tumor) and 2 canine osteosarcoma cell lines. PROCEDURE 3 antibodies for centrosome proteins (ie,(More)
Although it has been said that Syrian hamsters of the APA strain (APA hamsters) spontaneously develop glomerulosclerosis with age, more prominent and severe glomerulosclerosis with proteinuria as well as arteriosclerosis is induced in diabetic APA hamsters. In this study, in order to supply new information on APA hamsters, tests on renal function and(More)
Syrian hamsters of the APA strain (APA hamsters) have recently been demonstrated to develop atheromatous lesions in the aortic arches under the diabetic condition induced by a single injection of streptozotocin (SZ). Various lipoprotein receptors are reported to play important roles in atherogenesis mainly in vitro, while there are few reports on the(More)
Syrian hamsters of the APA strain (APA hamsters) develop spontaneous mesangial thickening in the renal glomeruli from an early age. They also develop focal and segmental glomerulosclerosis (FSG) at and after 6 months of age. In this study, histopathological, immunohistochemical and lectin histochemical examinations were conducted to clarify the modification(More)
Syrian hamsters of the APA strain (APA hamsters) develop spontaneous mesangial thickening in the renal glomeruli from an early age. They also develop focal and segmental glomerulosclerosis (FSG) at and after 6 months of age. In this study, histopathological, histochemical and electron microscopical examinations were conducted to clarify the age-related(More)
Streptozotocin (SZ) was inoculated intraperitoneally to male and female mice of ICR and BALB/c strains in a different way of administration (A: single injection and B consecutive 5 days-injection) and subacute renal changes were examined light and electron microscopically 8 weeks after SZ-administration. The following changes were detected: (1) reduction in(More)
