In early puerperium various biochemical changes develop in the organism. Considering the role played by MAO, DAO and histamine, and absence of a comprehensive study of this problem in this life period a study was carried out on 36 women, who were selected randomly from women giving birth through the normal pathway. Blood samples were taken in morning hours on the 1, 2 and 3 days of puerperium. In each case the activity of serum monoamine oxidase, diamine oxidase and blood histamine level were measured. The results obtained on various days of puerperium were compared. Statistical analysis was carried out using the t test for paired measurements. Increased serum MAO activity was found on the second day and was decreased then on the third day of puerperium, but it was still above the level on the first day. A successive decrease of serum DAO activity was noted in these three days of puerperium. The blood histamine level increased successively on the successive days of puerperium. Normal values of the activity of these substances in the serum were established in women delivering the fetus through the vagina. The lower normal range of MAO activity, extension of the range of DAO activity, especially of its upper range, and decreased histamine level were found. The authors discuss the causes of these results.
