[The influence of the exogenous melanin on the development of the second generation of the female Wistar rats exposed during the critical period of the pegnancy at the nonsterilizing doses of different rate means].

The purpose of this study was to estimate the radio-protective activity of melanin for the reproductive status of Wistar rats. Wistar rats were exposed in utero either to the single gamma-irradiation on the tenth day of embryogenesis with the dose of 1 Gy or to the chronic gamma-irradiation with the total dose of 1 Gy during the first 10 days of embryogenesis. Such things like the ability of the rats to conceive, the embryogeny and early postnatal ontogeny of rat's posterity were studied.
