title: [Toxicologic and pharmacologic study of tributyltin oxide (TBTO)].
abstract: Toxicological study on bis-(tributyl-tin) oxyde shows a delayed toxicity of this compound in acute experiments. The same result is obtained in sub-chronic study. Most of the animals die after a great loss of weight. In pharmacological study, T. B. T. O. depresses central nervous system, but his action on ortho and parasympathetic system is slight and non specific. In rat, rabbit and dog, the effect is a fall in blood pressure that result from a depression of the vascular smooth muscle. The death of the animal is due to respiratory arrest by a central mechanism.
