Experiments on rabbits have shown hyperlipidemia to develop within the first 48 h after a single intravenous injection of bovine serum albumin (BSA, fraction V). The mean concentration of blood plasma triglycerides (TG) was considerably higher than normal (by 262% after 24 and by 625% after 48 h). The cholesterol content was also elevated (by 80 and 270%, respectively). Following 7 and 14 days the lipid concentration returned to normal. The plasma post-heparin lipoprotein lipase activity (PHP-LPL) was lower 24 h and 7 days after BSA injection and the hypotriglyceridemic effect of heparin was less pronounced. The data obtained support the hypothesis that hyperlipidemia provoked by a single intravenous injection of BSA to rabbits results from low PHP-LPL activity and possible changes in TG-rich lipoprotein substrate affinity for the enzyme.

This study was performed to evaluate the effects of total polysaccharides extracted from Pleurotus ostreatus on type 2 diabetes. Rats were administered with high-fat diet and streptozotocin (STZ) to induce diabetes. The rats were then treated with 100, 200, and 400 mg/kg/d POP or vehicle for 4 weeks. Our experiments indicated that POP reduces hyperglycemia and hyperlipidemia levels, improves insulin resistance, and increases glycogen storage by activating GSK3 phosphorylation and GLUT4 translocation. Moreover, POP reduces the risk of oxidative damage by increasing superoxide dismutase(SOD), catalase(CAT), and glutathione peroxidase(GSH-Px) activities and decreasing malonaldehyde(MDA) level. These results suggest that POP exerts antidiabetic effect on STZ-induced diabetic rats.
