Effects of isoprothiolane and phytosterol on adipocyte metabolism and fatty acid composition of serum and tissue lipids in rats.
    The Journal of veterinary medical science, 1991, Volume: 53, Issue:5

    Isoprothiolane at a dose of 250 mg/kg or phytosterol 50 mg/kg was orally administered to rats once a day for 2 weeks. Basal [U-14C]glucose conversion rate to total lipids in isolated adipocytes of the rats was significantly decreased by treatment with isoprothiolane (54%) or phytosterol (82%). Adipocytes from the rats with isoprothiolane released less glycerol than those from control rats only at an epinephrine concentration of 10 microM. The serum level of total cholesterol was depressed by phytosterol ingestion. The level of non-esterified fatty acids (NEFA) was increased by isoprothiolane. Desaturation in fatty acid composition of phospholipid or cholesterol ester was observed in serum, liver and adipose tissue of the rats treated with either drug. These results suggest that either drug may have common effects by preventing lipid deposition into adipocytes and accelerating fatty acid desaturation in tissue lipids.

Effects of isoprothiolane and phytosterol on lipogenesis and lipolysis in adipocytes from rats of dietary fat necrosis.
    Nihon juigaku zasshi. The Japanese journal of veterinary science, 1990, Volume: 52, Issue:6

    To study effects of isoprothiolane and phytosterol on dietary fat necrosis, 3 groups of rats were fed hardened-tallow (HT) diet. Two groups of rats received either isoprothiolane (50 mg/kg) or phytosterol (20 mg/kg) orally once a day consecutively for 10 weeks. One group of rats received standard diet (CE-2) as a control. Fat necrotic lesions were observed in epididymal and perirenal adipose tissues from all rats in the 3 groups fed HT diet. Rats with fat necrosis were characterized by visceral type obesity and saturation in fatty acid composition of triglyceride in adipose tissue. The highest glucose conversion to total lipids was seen in adipocytes from the rats given phytosterol. There was no lipolytic response to epinephrine stimulation (1-100 microM) in adipocytes from the rats given only HT diet, while similar response of adipocytes from the 2 groups treated with either drug to those from the rats fed standard diet was observed. The levels of total saturated fatty acids of phospholipid in adipose tissue from the rats given either drug were lower than that of the rats given only HT diet. These data suggest that either drug alters fatty acid composition of phospholipid in fat cell membrane and enhances lipolysis of the cells.
