Oral administration of di(2-ethylhexyl)phthalate (DEHP) at 1000 mg/kg body weight to adult male albino rats maintained on low protein (LP) diet for 15 d resulted in a greater decrease in absolute and relative weights of the testis and in epididymal sperm count than in those rats maintained on a normal protein (NP) diet. A marked increase in the activity of testicular beta-glucuronidase and gamma-glutamyl transpeptidase (GGT) in the LP-fed animals suggested that LP diet enhanced the vulnerability of Sertoli cells towards DEHP. A greater decrease in the activity of testicular acid phosphatase, lactate dehydrogenase isoenzyme-X (LDH-X) and sorbitol dehydrogenase (SDH) in the LP-fed animals occurred in comparison to NP-fed animals. Degeneration of mature germinal cells in the LP-fed animals on exposure to DEHP suggested that LP diets enhance the susceptibility of the testis towards DEHP.

myo-Inositol biosynthesis has been examined in hypophysectomized and thyroidectomized male rats. After hypophysectomy, inositol-1-phosphate synthase [1L-myo-inositol-1-phosphate lyase (isomerizing), EC 5.5.1.4] in the reproductive organs and liver decreased markedly. At the same time, testicular acid phosphatase [orthophosphoric-monoester, phosphohydrolase (acid optimum), EC 3.1.3.2] and beta-glucuronidase (beta-D-glucuronide glucuronosohydrolase, EC 3.2.1.31) increased. Thyroidectomy caused a similar decrease in inositol-1-phosphate synthase in the liver but not in the reproductive organs. Follicle-stimulating in the liver but not in the reproductive organs. Follicle-stimulating hormone (follitropin) and luteinizing hormone (lutropin) restored the activity to at least normal levels in the testis, prostate, and seminal vesicle but not in the liver of hypophysectomized animals. Triiodothyronine and thyroxine stimulated liver synthase 30-fold in hypophysectomized animals. We conclude that inositol-1-phosphate synthase in the reproductive organs is under more or less direct control of the pituitary; in the liver, the control is mediated through the thyroid.
