To the treatment of rickets with seal oil

On the issue of the use of seal oil for the treatment of rickets in children, several works have already appeared in the Russian medical literature. So, in 1929, Levit and Mikhlina, in a work that came out of our clinic, reported on the basis of observations on 13 children about the satisfactory results of using this fat. In 1935, E. M. Lepsky and G. S. Tyamina published observations that also speak of the satisfactory effect of seal oil on children's rickets, despite the fact that when tested on rats, the content of vitamin D in this preparation was low.
