ABSTRACT
Objective: To study the influence of Centipede Acidic Protein(CAP) on the proliferation and collagen synthesis of cultured neonatal rat cardiac fibroblasts(CFb) induced by angiotensinⅡ(AngⅡ),and to explore the mechanisms of CAP on cardiac fibrosis.Methods: Neonatal rat cardiac fibroblasts were treated with AngⅡ to produce fibrosis model.The effects of CAP on proliferation of CFb were observed by MTT colorimetric assay,synthesis of collagen was observed by the hydroxyproline concentration.The NO contents were measured by Nitric acid reductase method.The c-myc expression was examined by semi-quantitative RT-PCR analysis.Results: Compared with that of control group,the proliferation,collagen synthesis and the levels of c-myc mRNA expression of CFb in the model group increased,while the NO contents decreased obviously(P
ABSTRACT
OBJECTIVE:To study the effects of Chongcaodihuang(CCDH)syrupus on immune function and antistress ability.METHODS:The experiments were carried out to investigate the effects of CCDH on weight of immune organs,the phagocytization of the monocytes by using the method of carbon particles expurgation,the content of antibody of hemolysin in serum,and time of swimming and hypoxia tolerance in mice.RESULTS:CCDH could enhance weight of immune organs,the phagocytization of the monocytes and increase the content of antibody of hemolysin in serum.It can also delay the time of swimming and strengthen hypoxia tolerance in mice.CONCLUSION:CCDH significantly improve immune function and antistress ability of mice.
