EFFECTS OF RIBONUCLEIC ACID AND RIBONUCLEIC ACID DEGRADATION PRODUCTS ON THE DEVELOPMENT,IMMUNITY,SEDATION AND HYPNOGENSISES OF MICE

To understand the regulating functions and regulating methods of ribonucleic acid (RNA),we investigated its effects on the development,immunity,sedation and hypnogensises of mice by ig mice with RNA or ribonucleic acid degradation products(RNADP).The results were:1.RNA could promote mouse capill more polishly,and increase testicle weight remarkably;RNADP could also promote mouse capill more polishly,but couldn't markedly increase testicle weight;Body weight of mouse was not increased markedly neither in RNA group nor in RNADP group.2.RNA and RNADP had the function of enhancing immunity.RNADP was better than RNA in promoting the functions of phagocytosis of peritoneal macrophage(PM) and hemolysis of blood serum hemolysin,but RNA was better than RNADP in promoting the transforming of lymphocyte in vivo. 3.RNA had the function of sedation and hypnogensis abservably,but RNADP hadn't.The conclusion is that RNA had remarkably the functions of promoting development,immunity,sedation and hypnogensis.The different regulating results between RNA and RNADP showed that RNA might not only be digested and absorbed in intestines as food,but also regulate the function of the body by act on the gastrointestinal tract before being digested.
