Prolactin and Bromocryptine Induced Changes in Liver, Adipose Tissue and Blood Lipids of Mature Male Bonnet Monkeys, Macaca radiata (Geoffroy)

[摘要] References(33)Cited-By(2)Effects of prolactin and bromocryptine on neutral and phospholipids of liver, adipose tissue and serum were studied in mature male bonnet monkeys. Hyperprolactinemia (ovine prolactin, 250μg/kg body weight/day, i.p. for 30days) elevated hepatic total lipids and phospholipids and decreased total and free cholesterol. While triacyl glycerol accumulated, mono-and diacyl glycerols diminished in liver and adipose tissues of prolactin treated monkeys. Concentrations of all phospholipid fractions, except sphingomyelin and cardiolipin in adipose tissue accrued in both tissues. Serum triacylglycerol, phosphatidyl ethanolamine, phosphatidyl choline and phosphatidyl inositol showed a significant increase in hyperprolactinaemic monkeys. Bromocryptine (1mg/kg body weight/day for 30days) treatment reduced serum phospholipids without altering hepatic or adipose tissue lipids. The present study indicates that hyperprolactinaemia leads to hyperlipidemia due to accretion of hepatic and adipose tissue triacyl glycerol and certain phospholipid fractions. Bromocryptine has a specific inhibitory effect on serum phospholipids.
