An examination was made of the relationship between serum level and liver content of vitamin A in normal rats and those under the influence of varying degrees of vitamin A depletion. The following points were observed:
- (1) An inverse relationship existed between blood and liver levels of vitamin A in normal male and female rats and those depleted female animals whose liver content ranged as low as 600 I.U./total liver.
- (2) When the total liver content fell below 600 I.U. in the males there was a parallelism between blood and liver levels.
