Lipids changes in rat tissues in experimental urolithiasis.

ABSTRACT

Total lipids, free and ester cholesterol, triglyceride and phospholipids were determined in plasma, liver, kidney and intestine in control and calculi producing diet (CPD) fed rats. Cholesterol, phospholipids and triglycerides were increased in plasma while they were decreased in all the three tissues of CPD fed rats, compared to that of control. Distribution studies of phospholipids in the tissues of treated rats showed marked decrease in the concentration of the major lipids, i.e., PC, PE, PI and SPH. However, significant increase in absolute concentration as well as percent distribution of phosphatidic acid in kidney of treated rats was observed.
