Behaviour of HPL and GH Plasmatic Rate in Pregnant Women at Different Times of Their Pregnancy during Dynamic Tests

Abstract

The effects of an oral or i.v. glucose load, of insulinic hypoglycemia, of Arg. and the effects of 2-deoxyglucose on the plasmatic concentration of HPL [human placental lactogen] and GH [growth hormone] in pregnant women at different times during their pregnancy were studied. None of the used tests seemed able to modify in any way the plasmatic concentration of HPL; the somatotropinic response to the different stimuli happens to be lower than that found in non pregnant women of the same age. Unlike what happens with GH, there does not exist a direct feedback between the modifications of plasmatic concentration of the main underlayers and HPL.
