title: [Humoral factors of the spleen in the regulation of the calcium content in blood plasma of rats].
abstract: Introduction of protein-free peptides-enriched spleen extract increases the calcium content in blood plasma of rats. After the effect of stress factor (long swimming) it falls. The value of the index under study increases in the splenectomized rats and remains unchanged after stress and introduction of the spleen factors. The most pronounced increase of the calcium concentration is observed in the case of experimental hypersplenism induced by methylcellulose introduction. The calcium-regulating effects of introduction of the enriched protein-free spleen extract and pharmacopoeial splenin preparation are compared. It is supposed that spleen contains two humoral factors of different chemical nature which are able to influence somewhat differently the calcium content in blood plasma.
