Human uterus in pregnancy, as it can be monitored by DSC examination -: A preliminary study

The myometrium is the main component in enlargement of uterus and plays essential role in labour contraction. Its physiologic and elastic state has a decisive role in the labour process. We have made the first attempt to find correlation between the thermal parameters of uterus and progress of gravidity. Significant differences were observed between cyclic, non-pregnant and postmenopausal state (0.69 and 0.98 J g(-1) calorimetric enthalpy as well as 60.6 and 63.1 degrees C for T (m)), as well as among the different gestational stages and complications. In case of twin pregnancy and dystocia we have found extremities: 0.37 and 1.34 J g(-1) calorimetric enthalpies, with 62 and 61.6 degrees C melting temperatures. DSC method seems to be promising tool to follow and understand different molecular changes in the myometrium during pregnancy and its complication of human labour.
