[Effect of gamma-hexachlorocyclohexane (Lindane) on the brain and serum tryptophan (author's transl)]

The effect of convulsant doses of gamma-hexachlorocyclohexane (Lindane) on the brain and serum tryptophan contents as well as on the serum FFA contents was studied. The results indicate a possible correlation between the fluctuations in the FFA, free serum and brain tryptophan concentrations. The total tryptophan concentrations increase as well as the brain tryptophan/free tryptophan ratio, with both experimental doses.
