title: [Various aspects of lipid metabolism in the rat testicle after sulpiride treatment].
abstract: Testicular lipids were extracted from 20 rats which had received 40 mg sulpiride per kg per day for 20 days as well as from 20 controls. The extracts were weighed and chromatographed on thin layer in order to analyse them for the main fatty constituants : phospholipids and neutral fats. In addition total cholesterol, triglycerides and lipid phosphorus were determined. The total testicular lipid content and the phospholipids were unaltered. The distribution of phospholipids wasn't influenced either. Among the neutral fats the precursors of steroid hormones such as cholesterol and its esters didn't show any modification. The triglycerides on the other hand suffered a significant decrease which was partly compensated in situ by the increase of free fatty acids. Since plasma electrophoresis didn't reveal a parallel increase of the complex albumin--free fatty acids, the hypothesis of an in situ lipolysis is proposed. But it is not possible yet to attribute to sulpiride the role of a direct activation on a testicular triglyceride lipase nor that of an indirect activator by way of prolactine for example.
