ABSTRACT
Objective To observe the protective effects of Diemailing Injection (DMLI) on myocardial ischemia-reperfusion injury in rats. Methods The myocardial ischemia-reperfusion model was induced by 30 min left anterior descending coronary occulusion and 24 h reperfusion in open-chest anesthetized rats. The changes of aspartate aminotransferase (AST), lactate dehydrogenase (LDH), MB isoenzyme of creatine kinase (CK-MB), superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) activities and malondialdehyde (MDA) contents in serum, and prostacycline (PGI2) and thromboxane A2 (TXA2) levels in plasma were determined. Results In rats treated by DMLI (with dose of 2. 5, 5 and 10 mL ? kg-1 i. v. at 30 min after coronary occulusion), the myocardial ischemia size (MIS) was significantly reduced, the AST, LDH and CK-MB activities in serum and the TXA2 level in plasma were declined, while PGI2 level in plasma and PGI2/TXA2 ratio were increased significantly. In addition, the LPO content in serum declined, SOD and GSH-Px activities in serum were increased markedly. Conclusion DMLI has protective effects on myocardial ischemia-reperfusion injury through improving free radicals metabolism, decreasing TXA2 level in plasma, increasing PGI2 level in plasma and PGI2/TXA2 ratio.
ABSTRACT
[Objective] To investigate the effect of Biejia Jian Decoction on serum transforming growth factor ?1 (TGF-pl) , tumor necrosis factor a (TNF-?), lipid peroxidation ( LPO) and superoxide dismutase ( SOD) in patients with hepatic fibrosis (HF) induced by chronic hepatitis B. Its effect was compared with lamivudine. [Methods] Fifty-three cases of HF were randomized to two groups: group A (n = 27) was treated with Biejia Jian Decoction and group B ( n -26) with lamivudine for oral use. Twenty volunteers served as the normal controls (group C) . Serum levels of TGF-?1, TNF-?, LPO and SOD were observed before and after treatment. [Results] After treatment, serum levels of TGF-?1 and TNF-a were decreased markedly in group A (P 0.05) . Serum LPO level was lower and SOD level higher in groups A and B than those in group C before treatment ( P 0.05) but the level in group B differed from that of groups A and C (P 0.05) but the level in group B did not decrease and differed from that of groups A and C ( P
ABSTRACT
[Objective] To investigate the effect of sporoderm-broken spores of Ganoderma Lucidum in the treatment of partial androgen deficiency of the aging male (PADAM) . [Methods] Random number table was used for the division of 138 PADAM cases. Sporoderm-broken Ganoderma Lucidum spores capsules were given orally to group A (n=80) and placebo to group B (n=58). The treatment course lasted 3 weeks. Self-scoring of physical ability, vasomotoricity, mental psychological state and sexual function was used to evaluate the therapeutic effect. Meanwhile, blood contents of testosterone (T), erythrocyte superoxide dismutase (SOD) and malondialdehyde (MDA) were determined and adverse reaction was observed. [Results] After a 3-week treatment, the scores of physical ability, vasomotoricity, mental psychological state and sexual function were decreased in group A (P 0.05) and the difference was significant between the two groups (P
ABSTRACT
[Objective] To observe the anti - aging effects and explore the mechanism of Qibao Meiran Pellet (QMP) and its modified prescriptions, including QMP with qi - invigorating and spleen - strengthening herbs, with kidney -nourishing herbs or with blood - activating and purgative herbs. [ Methods ] Ten - month - old model rats were established by D - galactose. Serum free radical levels and immune indexes in QMP group and various modified QMP groups were observed. [ Results ] QMP increased the activity of superoxide dismutase ( SOD). QMP combined with kidney - nourishing herbs or blood - activating and purgative herbs decreased the serum level of malondialdehyde (MDA) and increased the activities of glutathione peroxidase (GSH - Px) and SOD. Meanwhile, QMP combined with kidney -nourishing herbs increased interleukin - 2 activities. [ ConclusionJ QMP, mainly composed of herbs for nourishing liver and spleen, can delay the aging of rats, and spleen - strengthening herbs and blood - activating and purgative herbs also play an important role in the delay of aging. Furthermore, it is suggested that the anti - aging effect of herbal medicine is related to the sex.
ABSTRACT
To investigate the therapeutic effects of Lipi Huatan Jiangzhi Tablet(LHJT),80 cases of hyperlipenda were landomly allocated to LHJT group(50) and lypanthy group(30) and single-blindedtrial was applied.Blood lipids(total cholesterol,triglyceride,high density lipoprotein,apoprotein A andapoprotein B),blood theology and free radicals(lipid peroxide, superotide dismutase and glutathionesuperokidase) were observed.The results showed that the regulatory effect on lipid medslism in LHJTgroup was better and more stable; blood theology, free radicals and the main symptoms were more improved as comapared with lypanthy group. Meanwhile,the total effective rate of LHJT for patients withspleen-deficiency and phlegm-stagnation syndrome was higher than that with other TCM syndromes(P
ABSTRACT
The anti-aging effect of Yang Shou Dan (YSD) was studied. It was shown that YSD could obviously increase the activity of superoxicde dismutase (SOD) in erythrocyte, decrease lipid peroxides (LPO) in serum and in liver tissue and reduce the content of lipofucin in myocardium of mice. It could also prolong the mean life span, the half lethal period and the longest life time of drosophila melanogater. It is suggested that YSD exerts an anti-aging effect to a certain extent.
ABSTRACT
Polyporus Umbellatus polysaccharide(PUP) is a new medicine made by our institute. A model of aged mice was prepared by placing 2-month mice in an ozone circumstance (O_3 conoentration 1. 298 ppm) for 10 days. After the aged mice was fed with PUP for 10 days, the average body weight, body temperature and thymus coefficient can be increased to normal level, superoxide dismutase (SOD) activity of red cells and catalase activity of liver were increased, and liver lipoperoxide (LOP) reduced. It is suggested that PUP may be a good anti-aging agent.
