Chinese Traditional Patent Medicine.1992;0(09):-.

AIM: To study the determination of 5 kinds of cholic acid content. METHODS: Using single standard substitue (SSS), we assayed 5 kinds of cholic acid, such as cholic acid, deoxycholic acid, hyodexycholic acid, chenodeoxychoilc acid and ursodeoxycholic acid by HPLC/ELSD. and studied the influence of the additive substitutes (such as rabbit Serum, urine and Qingkailing extract) on the measure values. RESULTS: By using any one of the 5 kinds of cholic acid standard, the content in all the 5 kinds of cholic acid could be determined. CONCLUSION: Simply as well as credibly, the SSS method could be used in quality analysis, especially in complex matrix. Also, it proved a feasible way in quality control and research of fingerprint chromatography of TCM.

Haiying WANG ; Yiping CHEN

Chinese Traditional Patent Medicine.1992;0(09):-.

AIM: To investigate the influence of Fructus Arctii and its extracts to the renal pathological changes of diabetic rat and its protective mechansim METHODS: The rat model induced by 55mg/kg STZ once intraperitoneally was adoped as the diabetic nephropathy of early stage, the extract and the powder of Fructus Arctii were given to the diabetic rat for six weeks. We observed the changes of general condition, and examined the expressions of TGF-? 1 (transforming growth factor-? 1) mRNA and MCP-1mRNA (monocyte chemoattractant protein-1) by reverse transcription-polymerase chain reaction (RT-PCR). CONCLUSION: The ethanol extract of Fructus Arctii relieved renal pathological changes of diabetic rat. The mechanism perhaps was related to the reduction in the expression of MCP-1mRNA and TGF-? 1mRNA in kidney; The study proved that the ethanol extract of Fructus Arctii was more effective than its water extract and coarse powder.

Chinese Traditional Patent Medicine.1992;0(09):-.

AIM: To observe the hemostatic effect and hemostasis mechanism of XHJ (Auena fatua L.) oral Liqnid on animals. METHODS: Bleeding time (BT) and clotting time (CT) were measured by means of tail cutting and glass slide method on mice, Von willebrand factoe (vWF), prothrombin time (PT) and Kaolin partial thromboplastin time (KPTT) were observed by immunoterbidimerry and coagulase test, antithrombin Ⅲ(AT-Ⅲ) by chromophoric matrix method platelet count by tissue plasminogen activator (tPA), plasminogen activatore inactivator (PAI). CONCLUSION: The results indicate that XHJ has remarkable effect on hemostasis; Its mechanism is related to accelerating blood coagulatlon, inhibiting fibrinolytic activity, adding blood vessel endothelial cell release and improving platelet adhesiveness and aggregation.

Chinese Traditional Patent Medicine.1992;0(09):-.

AIM: To investigate the influence of Buxinqi Capsule (BXQ) on myocardial ischemia reperfusion injury in rats. METHODS: In this study, the experimental model was established by reperfusion for 60 minutes in rats after ligaturing left anterior descending coronary artery (LAD) for 30 minutes. Serum creatine phosphokinase (CPK), lactate dehydrogenase (LDH), superoxide dismutase (SOD) and malondialdehyodebis (MDA), area of myocardial infarction and occurrence of arrhymia were investigated. RESULTS: BXQ significantly decreased level of CPK and LDH and MDA, and obviously improved the activity of SOD, decreased reperfusion arrhythmias and arrhythmias severity index (ASI), and decreased the area of myocardial infarction. CONCLUSION: BXQ has protective effect on the damage of myocardia ischemia reperfusion in rats

Linzhong YU ; Hongxia SHAO ; Hui LIN ; Yaling XING

Chinese Traditional Patent Medicine.1992;0(09):-.

AIM: To evaluate the main pharmacological effect of Wunzhonganwei Soft Capsule. METHODS: Analgesic effect was investigated by hot plate test and writhing test, anti-inflammation effect by auricular swelling test in mice and toe swelling test in rat, anti-diarrhea effect by diarrhea test induced by rhubarb, effect on gastric emptying by phenolsulfonphthalein empty test in mice and effect on small intestine propulsive test by charcol powder propulsive rate test. RESULTS: Wunzhonganwei Soft Capsule enhanced thermal stimulation threshold in mice, decreased the occurrence of writhing caused by glacial acetic acid in mice, inhabited xylene-induced auricular swelling in mice and carrageenan-induced toe swelling in rat, decreased the number of loose stools induced by rhubarb in mice., inhabited the function of gastric emptying induced by metoclopramide or in normal mice, antagonized the inhibitory effect of gastric emptying induced by atropine and inhabited small intestine propulsive movement induced by neostigmineor or in normal mice. CONCLUSION: Wunzhonganwei Soft Capsule has the effect of anti-inflammation, analgesia, antidiarrhea and adjusting the function of gastrointestinal movement.

Evaluation of high-dose Senmai in treating patients with advanced cancer

Hua LU ; Rixing CHEN ; Meijuan WU

Chinese Traditional Patent Medicine.1992;0(09):-.

AIM:To make a evaluation of high-dose Senmai(Radix Ginseng Rubra, Radix Ophiopogonis, Fructus schisandrae.)(HD-SM)in treating patients with advanced cancer.METHODS:32 patients with advanced cancer were assigned to treatment group. And 28 cases were assigned to the control group. The treatment group received chemotherapy and HD-SM, the control group received chemotherapy and the routine supporting treatment (except HD-SM). The toxicity and effect of all patients were observed, and the value of HD-SM was assessed.RESULTS:All cases in treatment group received 4 chemotherapy courses according to plan. The toxicities were tolerable, and the effect was satisfactory. All cases in the control group were only performed 1 course of treatmeur.CONCLUSION:HD-SM can decrease the effect of chemotherapy and reduce chemotherapeutic toxicities, and it is a very effective supporting treatment in chemotherapy.
