Using a rat lens organ-culture model, the authors investigated whether PM could inhibit AGE formation in the diabetic lens. They measured lens AGEs and relevant biochemical mediators including glutathione and the activities of aldose reductase and glyoxalase in normal and diabetic rat lenses. The results of this study showed that PM failed to block cataract development. However, PM treatment wa...

The remodeling of cardiac gap junction contributes to the arrhythmias in a diabetic heart. We previously reported that high glucose reduced Cx43 protein level in neonatal rat cardiomyocytes. But, the effect and mechanisms of advanced glycation end product (AGE) on Cx43 expression still remain unclear. In this study, we measured the AGE receptor (RAGE) and Cx43 expression by immunohistochemisty ...

this study aimed to explore and validate a new juvenile osteopenic (jo) rat model then examine the efficacy of moghat (glossostemon bruguieri) as an alternative reversal therapy for jo. phytochemical screening analysis showed that moghat contains 5.8% alkaloids, 1.5% flavonoids and 13.2% total phenols. juvenile osteopenia was induced in 15 days old sprague- dawley female rats by feeding them fr...

Spontaneously Diabetic Torii-fa/fa (SDT fatty) rat is a new model of obese type 2 diabetes. SDT fatty rat exhibits obesity associated with hyperphagia. In this study, SDT fatty rats were subjected to pair-feeding with SDT-+/+ (SDT) rats from 6 to 22 weeks of age. The ratio of visceral fat weight to subcutaneous fat weight (V/S) decreased at 12 weeks of age in the pair-feeding rats. The intraper...

The Spontaneously Diabetic Torii-Lepr(fa) (SDT-fa/fa) rat, a new model of obese type 2 diabetes, shows obesity, hyperglycemia, and hyperlipidemia from 6 weeks of age. Diabetic complications such as nephropathy and cataract are observed with aging; however, blood pressure change with age has not previously been examined. In this study, blood pressure was periodically measured and the change was ...

There was no consistency of the induced levels among hepatoma lines, although all the rats were sacrificed exactly 6 hr after onset of feeding under controlled dietary regimens and 24 hr after a single intraperitoneal treatment with methylcholanthrene. Benzpyrene hydroxylase in fetal rat liver was very low in activity, and after birth a marked increase was observed. After administration of meth...

We measured the ability of neonatal to adult MRC-Wistar rat and Syrian hamster tissues to convert the esophageal carcinogen methyl-n-amylnitrosamine (MNAN) into the stable metabolites 2- to 5-hydroxy-MNAN and 3- and 4-oxo-MNAN. Slices or pieces of freshly removed tissues were incubated for 3 h with 23 microM MNAN and dichloromethane extracts were analyzed by gas chromatography-thermal energy an...

We measured the ability of neonatal to adult MRC-Wistar rat and Syrian hamster tissues to convert the esophageal carcinogen methyl-namylnitrosamine (MNAN) into the stable metabolites 2to 5-hydroxyMNAN and 3and 4-oxo-MNAN. Slices or pieces of freshly removed tissues were incubated for 3 h with 23 ¿tM NAN and dichloromethane extracts were analyzed by gas chromatography-thermal energy analysis. T...
