9bility of 0.999, it can be argued that the average value for a larger sample will not exceed the range found.
2) The mean value of the content of lipid hydroperoxides of blood plasma was 32.78 nmol / ml, the median was 31.8 nmol / ml, the standard deviation was 3.2 nmol / ml. Confidence interval: (28.33; 37.24) nmol / ml. With a probability of 0.999, it can be argued that the average value for a larger sample will not exceed the range found.
3) The mean value of the content of diene conjugates of blood plasma was 39.38 nmol / ml, the median was 39 nmol / ml, the standard deviation was 2.5 nmol / ml. Confidence interval: (35.83; 42.94) nsol / ml. With a probability of 0.999, it can be argued that the average value for a larger sample will not exceed the range found.
Conclusion
Taking into account that the normal LPO indices are equal to: malondialdehyde - less than 2.5-6.0 nmol / ml, lipid hydroperoxides - 24.17-26.3 mol / l, diene conjugates - 38.45-73.4 nmol / ml, it can be concluded that:
1. the average Malonialdehyde content does not go beyond the standard values.
2. the average index of the content of lipid hydroperoxides exceeds the upper limit of standard values;
3. the average content of diene conjugates does not go beyond the standard values.
It is also necessary to note the finding of confidence intervals for the values of malonic dialdehyde and diene conjugates contained in the blood plasma, within the standard values, therefore, for large samples, the average values of these indicators will also remain within the norm. But taking into account the excess of the norm of the average content of lipid hydroperoxides, we can not give a definitive answer about the effectiveness or ineffectiveness of AOS work. To fully display the ratio of LPO-AOS, it is necessary to analyze the plasma content of ceruloplasmin, vitamin E and conduct an integral assessment of oxidative stress.

Abstract Salivia miltiorrhiza is a traditional Chinese medicine, which is extensively used in treat-
ment of cardiovascular treatment. The water-extractable component of the medicinal herb Danshen(Sal-via miltiorrhiza) is Danshensu, which had become one of the research central point. This study summarizes its pharmacological research of danshensu focused on the characteristics of the activity.
Keyword: Salivia miltiorrhiza; Danshensu; pharmacological actions
Introduction The family of Labiatae includes Salvia miltiorrhize, which the dried roots were called dansh-en. Traditional Chinese medicine of danshen was often used for treatment of cardiovascular diseases, such as effective for promoting blood circulation, relieving blood stasis, angina pectoris, myocardial infarction and stroke. Mechanism may involve that Danshen has ability to enhance of antioxidant defenses activities and reduce or eliminate the free radicals. Meanwhile, Danshen has also been proved to attenuate the increased calcium in cells caused by anoxia-reoxygenation in the isolated ventricular muscle cells. It decreases transformation of xanthine oxidase from xanthine dehydrogenase and reducing the production of oxygen free radicals[1].
The components of Danshen can be divided into lipid-soluble and water-soluble. The lipid-soluble fraction contains that more than 30 diterpenoid tanshinones. On the other hand ,the water-soluble fraction includes that salvianolic acid B lithospermic acids, protocatechuic acid. rosemarinic acid. Water decoction is the most commonly used method of preparing Chinese folk medicine for human consumption. So, the putative active components of its aqueous extract are Danshensu. We hope more viewers will appreciates the approach of traditional Chinese medicine[2].
Pharmacological actions of Danshensu Danshensu improves of cardiovascular dysfunction
Myocardial hypertrophy caused by adaptive response of the heart muscle for overload of blood. The compensatory drawbacks, mainly because of myocardial hypertrophy increased aerobic, and coronary blood flow, often can't meet their needs, so the hypertrophy myocardial function if cannot maintain normal for a long time, finally induce to cardiac failure. Tang[3] and others evaluated the protective effect of the myocardial hypertrophic rats induced by Danshensu, and the frist reported that Danshensu can reverse the middle crevice of the mind.
Prevention and treatment of atherosclerosis Endothelial injury is recognized as the initiating factor of atherosclerosis. Low density lipoprotein, which induces the proliferation of smooth muscle cells that an important factor of atherosclerosis. Zheng[4]discovered that Danshensu can significantly reduce expression of PDGF-BB bu suppress low density lipoprotein. The results showed that the anti-oxidant low density lipoprotein can reduce the proliforation of the smooth muscle cells, which may be reponsible for lowering the expression level of PDGD-BB.
Danshensu has effect of anti-cancer Zhang[5] evaluated with antitumor activity of B16F10 melanoma cells and HUVEC proliferation, but decline the expression of MMP-2,9 and VEGF in the cells. In animal experiments, Danshensu significantly inhibits spontaneous and experimental B16F10 melanoma cells models of transfer. So these results suggest that Danshensu can be an anti-tumor effect by inhibiting tumor angiogenesis and tumor invasion[6].
Conclusions To sum up, with deepening the research, which is increasingly clear. Phaarmacological activities and mechanisms of continuously new pharmacological effects were found, and hope that with the early in disease prevention and control can be made full use of propotion the development of traditional Chinese medicine moderniz
