Abstract
The author studied the distribution of thiamine in organs of young albino rats at various stages of suckling and weaning period. Thiamine content in all of the organs increased with the lapse of time after birth and reached the highest value after weaning, but transitory decrease of thiamiane was observed in liver, kidney, heart and cerebrum immediately after birth. The thiamine contents of skin and hair increased rapidly after birth. The thiamine in stratum germinativum of epidermis and hair follicles reached the highest value, prior to weaning. Nervous cells in cerebrum and epithelium of digestive tracts showed a relatively high level of thiamine at the day of birth.
