Objective To observe the effects of modified Yigong Powder (MYP) combined with chemotherapy on transplanted hepatocarcinoma of mice and to study its mechanisms. Methods Hepatocarcinoma 22 mouse model was established and then was used to observe the attenuating and synergic effects of MYP when applied together with 5-fluorouracil (5-FU). After 8 days of treatment,the tumor-inhibiting rate,activity of natural killer (NK)cells and interleukin-2 (IL-2) and small intestinal malondialdehyde (MDA) content were examined. Results MYP combined with 5-FU could increased the tumor-inhibiting rate to some extent and improve the immune function by increasing immune organ weight and increasing the activity of NK cells and IL-2. MYP combined with 5-FU could also reduce the 5-FU-induced intestinal injuries by relieving the damage of free radicals and inhibiting the lipid peroxidation and a good prognosis was expected in tumor-bearing animals treated with chemotherapy. Conclusion MYP exerts an attenuating and synergic effect when used together with 5-FU in treating tumor-bearing mice and its mechamism may be related to the improvement of immune function and reduction of intestinal injuries.

Objective To observe the effect of Ganoderma Lucidum (GL) on counteracting lipid peroxidation in cultured vascular smooth muscle cell(VSMC)and to explore its therapeutic mechanism for atherosclerosis. Methods The effects of GL on the content of lipid peroxide(LPO)and the activity of superoxide dismutase(SOD)in medium were studied . Results GL decreased LPO content and increased SOD activity in a dose-effect manner. Conclusion GL can counteract the lipid peroxidation in VSMC and its therapeutic mechanism for atherosclerosis may be related to the counteraction of lipid peroxidation and enhancement of endogenous antioxidase activity.
7.Experimental Studies on Anti-Epileptic Action of Qi-Tonifying,Wind-Calming and Phlegm-Eliminating Herbal Medicines
Traditional Chinese Drug Research & Clinical Pharmacology 1993;0(04):-
Objective To study the mechanism of herbal medicines with the actions of tonifying Qi,calming wind and eliminating phlegm in treating epilepsy. Methods Rat models of chronic epilepsy were induced by penicillin. Changes of electrocorticogram (ECOG) and the contents of cerebral gamma-aminobutyric acid (GABA) and glutamate (GLU) in rats were observed. Results Radix Astragali increased the content of GABA and the effect was stronger with Borneol Syntheticum added but had less effect in decreasing GLU. Both Bombyx Batryticatus and Arisaema cum Bile could decrease GLU content and Arisaema cum Bile in particular. The effect of Radix Astragali was stronger in decrease of ECOG frequency but weaker than that in modifying the amplitude of ECOG,while Bombyx Batryticatus and Arisaema cum Bile were in the contrary. The effect of Radix Astragali in improving ECOG did not differ from that with Borneolm Syntheticum added. Conclusion Qi-tonifying,wind-calming and phlegm-eliminating herbal medicines are effective in treating epilepsy and their mechanism may be related to the regulation of electrocorticogram and the content of cerebral GABA and GLU.

Objective To provide evidence for the pharmacological action of blood-activating and blood-stasis-dissipating medicines by studying the influence of Zhenxintong Oral Liquid (ZOL) on thrombus-associated marker levels in coronary heart disease with blood-stasis syndrome. Methods Forty male Wistar rats were randomly allocated to 5 groups: normal group,model group,large-dose ZOL group,small-dose ZOL group and Compound Danshen Drip Pill(CDDP) control group. Blood-stasis models were established by peritoneal injection of dexamethasone (0.25mg?kg-1?d-1). After 8 days of treatment,levels of activated partial thromboplastin time (APTT),antithrombin -Ⅲ(AT-Ⅲ),tissue-type plasminogen activator (t-PA) and tissue-type plasminogen activator inhibitor (PAI) in blood from abdominal aorta were determined. Results AT-Ⅲlevel in the two ZOL groups and in CDDP control group was significantly higher than that in model group(P 0.05). t-PA level was higher and PAI level was lower in large-dose ZOL group than that in CDDP control group (P

Objective To observe the effect of Shengmai Chenggu Prescription (SCP) on the damage of endothelial cells (EC) induced by endotoxin. Methods EC obtained from rabbit's aorta were cultured and were treated with endotoxin and serum containing SCP respectively. Histological changes and function of the cultured cells were observed under light microscope and electron microscope and with MTT method . Results Endotoxin could result in the pathologic injury of cultured EC and inhibit the proliferation of the cells. Serum containing SCP could increase the activity of EC and promote its proliferation. Conclusion SCP can protect endothelial cells from damage induced by endotoxin.
