Synthetic human pancreatic polypeptide stimulated pancreatic somatostatin secretion by isolated rat islets and by the isolated perfused rat pancreas. In contrast, synthetic bovine pancreatic polypeptide and the C-terminal hexapeptide had no effect on somatostatin secretion. Synthetic human pancreatic polypeptide had only a mild stimulatory effect on glucagon secretion at the highest concentrati...

Marigold flower extract (MFE), a natural source of xanthophylls, was added to the diets of hens at different concentrations (0, 150, 250, and 350 mg/kg of diet) to determine the effects of MFE on hen performance, physical characteristics of egg quality, and carotenoid content of the egg yolk of hens housed in enriched cages. Additionally, the highest dose of MFE (350 mg/kg) was tested under com...

All mammalian tissues so far examined, with the exception of adult brain, are capable of incorporating acetate carbon into cholesterol (l-5). It has been estimated that man synthesizes in the neighborhood of 1.5 gm. of cholesterol per day, a quantity apparently exceeding that ingested when an ordinary mixed diet is fed (6). According to Chevalier (7), the laboratory rat synthesizes about 43 mg....

The effect of Bacillus thuringiensis toxin Cry1Ac on the behaviour of a laboratory-selected resistant population (72-fold) of Helicoverpa armigera on Bt-cotton was evaluated. Compared with non-Bt-cotton and Cry1Ac toxin incorporated in semi-synthetic diet, resistant larvae reared on Bt-cotton had only 0.13% survival and slower development. The results suggest that Cry1Ac from Bt-cotton exerts a...

BACKGROUND Rats fed a high-fat and high-sucrose (HF) diet develop hepatic steatosis and hyperlipidemia. There are several reports that a change in nutritional status affects hepatic levels of drug-metabolizing enzymes. Synthetic inulin is a dietary component that completely evades glucide digestion. Supplementing a HF diet with inulin ameliorates hypertriglycemia and hepatic steatosis, but not ...

OBJECTIVE To develop a new polycystic ovary syndrome (PCOS) rat model suitable for exercise intervention. METHOD Thirty six rats were randomly divided into three experimental groups: PCOS rats with high-fat diet (PF, n = 24), PCOS rats with ordinary diet (PO, n = 6), and control rats with ordinary diet (CO, n = 6). Two kinds of PCOS rat model were made by adjustment diet structure and testost...

This study was aimed at evaluating the blood glucose level, hepatic biomarkers and histology of alloxan induced diabetic rats fed with Sesamum indicum compounded diet. Thirty-Six male albino were divided into nine groups (normal control, standard drug-glibenclamide treated, 15%, 30% 60% diet normal diabetics after 14 days) four each lasted for 21 days. The induction diabetes done by a single do...

To come to a better understanding of the diet-induced cholesterol-ester storage in the gerbil liver, the reactions of the gerbil to 0.2% of cholesterol in the diet during 4 weeks were compared with those of the rat consuming the same diet. The major reason for the increased hepatic cholesterol-ester storage in the cholesterol-fed gerbil is the low cholesterol turnover in this species. This cont...
