There is lack of basic information about peripheral melatonin level and its relationship with gestational hormones i.e., estrogens and progesterone, in human females. The present study addressed this issue and aimed to find the relationship between the levels of melatonin and estrogen and progesterone during different weeks of gestation, during parturition and during post-partum. The data suggest that there is a definite ratio of melatonin with both the steroids hormons before and during gestation as well as post-partum. An inverse relationship between the levels of estrogen and melatonin was observed in non-pregnant and post-partum women, while a direct relationship was observed during gestation. These two different types of hormonal relationships might be essential for maintenance of pregnancy. The inverse relationship of melatonin with progesterone during parturition may serve as a signal for parturition.Keywords

Phosphorylation of thymidine, a key step in pyrimdine salvage pathway involved in DNA synthesis is catalyzed by Deoxythymidine kinase [Thymidine kinase (TK)-ATP: thymidine 5'-Phosphotransferase, EC: 2.7.1.21]. Several authors correlated changes in TK activity and 3H-Thymidine incorporation into DNA of various tissues or with cell divisions or under influence of EGF (Lewinski et al., 1997) and found that the relationship was a proportional one (Kahn et al, 1980; Zieve 1985).- Melatonin, Gestation and Fetal Development
