Spleen extracts, its preparation method and use

Abstract

The invention discloses a spleen extract prepared by extracting and preparing the spleen tissue of mammals other than humans. The spleen extract is obtained through the steps of fat removal, homogenization, freeze-thaw crushing, precipitation, and ultrafiltration of the spleen tissue of mammals. , containing the following components: polypeptides, free amino acids, nucleic acids, total sugars, all of which have molecular weights less than 10,000 Daltons; Thrombocytopenia, multiple infection syndrome, etc.), respiratory and lung infections, habitual cold, chronic hepatitis B, mumps, recurrent aphthous ulcers and other diseases, in the preparation and treatment of leukopenia caused by radiotherapy and chemotherapy, leukemia, Application of drugs in aplastic anemia, lymphoma and other malignant tumors, improvement of malignant transformation of tumor patients, virus infection, improvement of postoperative or adjuvant drugs in severe patients who are weak.

Description

【Technical field】

[0001] The present invention relates to a spleen extract, its preparation method and its use, in particular to a spleen extract prepared by extracting and separating from the spleen tissue of mammals other than humans, its preparation method and its use, belonging to field of pharmaceutical preparations. 【Background technique】

[0002] As we all know, there are many various nutrients and active ingredients needed by the human body in mammals, and there are many reports on the extraction of active polypeptides from the heart, liver and muscle tissue of mammals.

[0003] The spleen is the peripheral immune organ of mammals, and it is also one of the organs with the most vigorous metabolism in animals. Because it is rich in basic cell nutrients and cytokines, especially active ingredients that promote cell metabolism such as polypeptides, free amino acids, Nucleic acid and various sugars have received extensive attention from researchers. The research work o...
