title: Immunomodulatory effects of gamma-HCH (Lindane) in mice.
abstract: Mice were fed for 24 weeks with three different subtoxic dosages of gamma-HCH (0.012, 0.12 and 1.2 mg/kg) mixed in powdered feed. The immunological profile was assessed at an interval of one month during the entire exposure period. Both the cell mediated and humoral components of immunity showed a biphasic response characterized initially by stimulation followed by suppression in a dose dependent manner. However, gamma-HCH did not affect the functional properties of peritoneal macrophages. Histological changes in lymphoid organs were in accordance with the biphasic immunomodulatory effects of gamma-HCH.
