An early peak of absorption was detected in plasma 6 h after topical treatment of male Wistar rats with a commercial preparation of 1% lindane (Plomurol). Higher plasma levels were observed after repetitive doses of 60 mg/kg b.w., the amount recommended for the treatment of scabies and pediculosis in humans in several countries. A residue level of 7.4±0.67,ag/g was found in testicular tissue 6 h after a single daily topical application for 4 consecutive days. The ultrastructural study of testicular interstitial cells exposed to dermal application of lindane (Plomurol®) revealed widespread damage of a great number ofLeydig cells, some ofwhich were completely disintegrated.
