Regulation of lactation and the content of thyroid hormones in the milk of puerperants and in food products for supplementary feeding of children

Regulation of lactation and the content of thyroid hormones in the milk of puerperants and in food products for supplementary feeding of children

The content of follicule stimulating hormone (follitropin, FSH), luteinizing hormone (lutropin, LH), thyrotropin (TSH) and prolactin was studied in the serum of pregnant women and puerperants; also the thyroxine (T4), triiodothyronine (T3), T4-binding globulin (TBG) levels, and the T4-binding capacity of proteins and free T4 index were determined in the serum and milk of puerperants during the 1st wk of lactation. The serum FSH, LH, TSH and prolactin concentrations underwent definite changes connected with physiological reconstruction of the organism at these periods. The milk T4 and T3 levels showed a sharp elevation by the 6th day of lactation, this correlating with the changes in the serum. The milk TSH concentration was much lower than in the serum; the same regularity was revealed for the protein T4-binding capacity. The free T4 index is exceedingly high in milk, being much greater than that in the serum. Of the 10 food products for supplementary feeding of children an insignificant amount of T4 was revealed in 2 only. No T4 was found in cow milk.

Average figure slightly higher for the yeast-fed group, rising somewhat with the fat as lactation advanced. As determined by rat feeding, vitamin D co...
