Specifics of vitamin a deposition in certain mammals


, : Specifics of vitamin a deposition in certain mammals. Byulleten' Moskovskogo Obshchestva Ispytatelei Prirody Otdel Biologicheskii 90(6): 63-70

Content of vitamin A was examined in the liver of 825 specimens representing 13 mammals species. Among phytophagous animals coprophagous (hares, the chinchilla) are distinguished by relative constancy of the vitamin A accumulation. Herbivorous (the musk-rat, coypu) are provided with the vitamin from daily feeding and there are little vitamin deposits in the liver. The European elk suffer from the lack of vitamin A in winter. Predatory animals have well expressed ability to deposit vitamin A in their organisms. There are certain specific differences in abilities to the vitamin A deposition. Recommendations are given concerning additional forage for wild animals with feed containing carotene or vitamin A.

The influence of dosing time on the embryotoxicity of sodium valproate (valproic acid, VPA) was investigated in ICR mice under a light-dark (12: 12) cycle. A significant circadian rhythm was shown for VPA-induced embryotoxicity, with the highest v...

The storability of onion seeds at ambient temperature was enhanced by ultra-drying. The aging process of short-lived onion seeds was delayed by ultradry storage. Imbibitional injury of ultradried seeds (breakage of embryonic roots) was alleviated...
