3.A New Method for the Extraction of Tea-Polyphenols
Chinese Traditional and Herbal Drugs 1994;0(03):-
A new method for the extraction of tea-polypbenols (TP ) from tea using AlCl3 as precipitating agents was proposed. Compared with tbe traditional extraction method using organic solvents, it is shown that the new method is simple and can be operated easily. The extraction rate of TP by the new method could reach 10.5% and the content of the effective ingredients of TP could reach over 99.5%
4.EFFECTS OF GINSENOSIDES AND PANTOCRINE ON THE FUNCTION OF REPRODUCTIVE ENDOCRINE SYSTEM IN MALE RATS
Chinese Pharmacological Bulletin 1986;0(04):-
In vitro experiment, results showed the that the LH secretion of adenohypophysis incubated with Ginsenosides ( G ) and Pantoc-rine ( P ) was significantly increased, similar to the exciting effect of LRH which stimulats LH secretion. By addition of G or P and Indomethacin (an inhibitor of PGs synthesis) at the same time, however, the LH secretion was significantly decreased. It appears that PGs may be involved in the regulation of the exciting effect of G and P on LH secretion. The experiment in vivo also demonstrated that in healthy young male rats injected with P by S.c.,thetestosterone content in plasma had significant increase, that the binding capacity of testicular tissue to 125I-HCG (receptor function) did not change clearly.

Objective To study the influence of seawater immersion on hemostatic function after burn in dogs. Methods Twenty healthy adult mongrel dogs of beth sexes weighing 12-15 kg were randomly divided into two groups: immersion group(n=10) and control group(n=10). The animals were anesthestized with 3% pentobarbital 30 mg?kg~(-1) i.v., intubated and mechanically ventilated. 5F Swan-Ganz catheter was placed via right internal jugular vein. 10% of the skin on the back was burnt(second degree). In immersion group the animals were immersed in seawater containing salt 25.3 g?L~(-1)(pH8.1, T21-23℃) with head and neck kept above water for 4h. In control group the animals suffered second degree burn of same area without being immersed in seawater. Blood samples were taken from Swan-Ganz catheter before burn(baseline)and 4,7,10,20,28 h after burn for determination of(1) circulating endothelial cell(CEC) count, (2)tissue-type plasminogen activator(t-PA), (3) plasminogen activator inhibitor(PAI) and (4) thromboxane B_2/6-keto-prostaglandin F_(1?)(TXB_2/6-k-PGF_(1?)). At the end of the experiment lung tissue was obtained for microscopic examination. Results The blood CEC count, PAI-1 level and TXB_2/6-k-PGF_(1?) ratio significantly increased while t-PA level significantly decreased at 4 h after burn in control group but at 4-28 h after burn in immersion group. The differences between the two groups were significant. Microscopic examination of the lung showed some thrombi in immersion group. Conclusion Burn causes acute damage to the endothelial cells of the whole body and disorder of hemostasis. They are more severe and last longer after seawater immersion.

Objective To study the influence and mechanism of seawater immersion on endothelial cell injury sustained by burn firearm combined injury to improve the early therapeutic efficacy. Methods The dogs with burn firearm combined injury were randomly divided into two groups: immersion group and control group. In immersion group, the dogs were immersed in seawater for 4 hours, then taken out from seawater. Blood samples were collected from central vein at 4 h, 7 h, 10 h, 20 h and 28 h following wound for the detection of changes of the circulating endothelial cells (CEC) and von Willebrand Factor (vWF). The same procedures except immersion were performed in the control group. Results The levels of CEC and vWF elevated at 4 h and 7 h following wound in control group( P

Objective To investigate the effect of seawater immersion on the hemostatic function of endothelial cells in dogs sustained burn firearm combined injury and the mechanisms. Methods Dogs with burn firearm combined injury were randomly divided into two groups: immersion group and control group. Dogs in immersion group were immersed in seawater for 4 h, and then taken out from seawater. Blood samples were collected from central vein before wound, immediately after immersion, at 4, 7, 10, 20, and 28 h after immersion to detect the changes in circulating endothelial cells (CEC), tissue type plasminogen activator (t PA), plasminogen activator inhibitor (PAI), and thromboxane B 2/6 keto prostaglandin F 1? (TXB 2/6 K PGF 1? ). Dogs were sacrificed at 28 h after wound for the purpose of pathological examination of the lung tissue. The indices detected except seawater immersion in the control group were the same as those in the immersion group. Results In the control group, the levels of CEC, PAI 1, and TXB 2/6 K PGF 1? increased, but the level of t PA decreased at 4 and 7 h after wound. However, in immersion group, the levels of CEC, PAI 1 and TXB2/6 K PGF1? kept increasing, but the level of t PA kept decreasing at 4, 7, 10, 20, and 28 h. Each index in immersion group from 4 h to 28 h after wound was significantly different from that in the control group ( P
