Pregnancy maintenance with corticosterone in protein-depleted rats: a study on fetal protein composition.

A pregnancy maintenance of only 8% was obtained when rats were fed a protein free diet throughout gestation. Administration of 5 mg corticosterone on each of days S to 9 improved pregnancy maintenance to 62%. In comparison with fully fed rats, fetal weight and fetal protein (concentration and total) were significantly less in the corticosterone maintained protein deprived animal. However, fetal hepatic protein, RNA and DNA concentrations compared favorably with those of the full fed animal; total content of each of these constituents was subnormal in protein deficiency. Thus total cell numbers were fewer but cell size (P/DNA) was normal. Corticosterone may serve to mobilize amino acids and to release prolactin as a potential mode of action.
