Health Benefits
1. Anemia caused by malignancy or chemotherapy
In the investigation of the effects of fractions A and B from enzyme-digested traditional Chinese medicine colla corii asini on mice with 5-fluorouracil-induced anemia, found that
This treatment significantly increased serum GM-CSF and EPO level and lowered serum transforming growth factor (TGF-beta) level. These results suggested that fractions A and B promoted hematopoiesis by activating immature granulocyte and erythroid cells, partly by stimulating GM-CSF and EPO secretion and suppressing TGF-beta release. Identification of a specific peptide or protein is still required for the development of a novel medicine for anemia caused by malignancy or chemotherapy, according to “Hematopoietic effect of fractions from the enzyme-digested colla corii asini on mice with 5-fluorouracil induced anemia” by Wu H, Yang F, Cui S, Qin Y, Liu J, Zhang Y.(1)
