Dr. Salil Kumar Mandal

Abstract :

Vitamin A is essential for the vision and for the development of the body including the ain as some Scientist suggested. Normally in albino rats and in human being the serum level in resting condition is 44.83 IU/ 100ml and 91.00 I.U/ 100ml respectively. After oral administration in rats this level is increased by threefold in the serum. In liver also this level is increased many fold after an oral dose . But no vitamin A was detected in rat ain before and after oral dose . In the human being CSF (cereo spinal fluid ) was investigated for vitamin A but no vitamin A was detected. From these experiments it can be concluded that possibly there is blood – ain and blood— CSF– barrier for vitamin A
