Activation of melanogenesis in the beagle by a vasodilator, mecinarone.

Mecinarone (18.25 mg/kg twice a day orally for 6 months) induces an increase in melanin content of pigmented skin and mucosae in the Beagle dog. This effect is reversible. This effect is not due to a central or an endocrine mechanism because plasma levels of M.S.H., A.C.T.H. and cortisol remain normal. High levels of Mecinarone are found in melanized areas (skin, hair and non tapetal area of the eye). This effect is reversible. In contrast wih the Beagle, studies in pigmented guinea-pig and rabbit have been negative.

Hepato- and thyreotoxicity of tifemoxone.

The oral toxicity of Tifemoxone, phenoxymethyl-6 tetrahydroxazine-1, 3 thione-2, a new potential antidepressant was studied during 6 months in rats at 30, 85 and 230 mg/kg/d and in beagle dogs at 10, 55 and 300 mg/kg/d. Thyroid hyperplasia and hypoactivity were observed in the rats and dogs plasma triiodothyronine, determined in dogs, was modified. A dose dependent hepatotoxic effect was observed in the rats and dogs. In dogs at low dose, one animal died after B.S.P. test. Water consumption and urinary volume increased, weight loss and anemia appeared at high doses in both rats and dogs. Hair loss was observed in rats and convulsions in dogs. In conclusion, Tifemoxone like tetrahydroxazine thione and some derivatives caused thyreotoxicity, hairlessness and increased in water comsumption and diuresis and in addition it had strong hepatotoxic effect especially in the dog.
