ABSTRACT
AIM To investigate the relationship between sinomenine distribution and its organic toxicology in rats so as to give some pharmacological data for clinical application of sinomenine. METHODS Three kinds of administration plans were designed in the experiment, ie sinomenine was ip administered at the dosage of l50 mg*kg-1 per day, repreat-dosed for 6 wk and suspended the drug for 1 wk after 6wk repeat-doses．At the end of the each administration plan，the animals were sacrificed and their blood and their main internal organs were collected for the purpose of measurement of sinomenine concentration in each sample by HPLC. Meanwhile，the histopathological and serological examinations were also done in the experiments. RESULTS The sinomenine concentration in rats internal organs were in order of liver, heart, lung and brain either in single-dosed treated animals or in repeat-dosed treated animals for 6 wk. However，the concentration of sinomenine could not be detected by HPLC after l wk drug-suspension，the histopathological examination showed that sinomenine at the dosage of l50 mg*kg-l per day for 6wk treatment could slightly damage liver ce11s, dominant1y caused the cell edema，but no any influence on the sero1ogy of liver and kidney. Sinomenine ip could also cause a mild hyperaemia of the rats heart tissues but no any histopathological changes had been observed. In testis tissues no sinomenine had beed detected although the animals were treated by repeat treatment for 6 wk and no any histopathological changes had been found yet. However, Sinomenine could partialy inhibit the sperm vitalities and amount of the dead sperms were a1so augmented. It was similar to in vitro eperiments. These influences of sinomenine on testis could be quickly recovered by drug suspension. CONCLUSION Sinomenine concentration were in order of liver, heart, kidney, lung and brain either in treatment by single dose or by repeat-dose administration. The histopathological changes were only abserved in liver cells of the animals which indicates that it should be in consideration of the liver functions during treatment course of the drug.
ABSTRACT
Objective To observe the effects of cyclovirobuxinum D(Cvb-D)on the myocardium cell apoptosis of myocardial ischemia rats.Methods The rats were given Cvb-D 0.55,1.1 and 2.2 mg/kg orally per day for 21 days respectively.The myocardial ischemia model was induced by isoprenaline intraperitoneal injection.Myocardium tissue was observed under light microscope and end labelling TUNEL method was used to determine the cell apoptosis.Then the average percentage of apoptosis cell was figured out to evaluate the effect of Cyb-D.Results Cvb-D obviously lightened isoprenaline-induced myocardial pathological changes such as turbulence of myocardial fiber,plasmolysis of necrotic cell,inflammatory cell infiltration of necrotic interstitial region.Cvb-D remarkably inhibited myocardium cell apoptosis of myocardial ischemia rats caused by isoprenaline.Conclusion Cvb-D has the action of ameliorating myocardium cell apoptosis caused by myocardial ischemia.
ABSTRACT
Objective To determine the concents of palmatine hydrochloride and berberine hydrochloride in the preparation of Fu Yan Xiao Lotion(FYXL).Methods The HPLC method was established for the determination of palmatine hydrochloride and berberine hydrochloride in the preparation of FYXL.The chromatographic column is Agilent Extend C18(4.6mm? 150 mm,5 ? m),mobile phase consists of water-acetonitrile(40 ∶ 60,3.5 g potassium dihydrogen phosphate and 1.5 g sodium dodecyl sufate per 1 000 mL),column tempreture was 30 ℃,and the flow rate was 1.0 mL/min.The detection wavelength was 345 nm.Results A good linearity is obtained in the range of 0.062 5 ? g to 1.250 ? g of berberine hydrochloride,and 0.068 6～ 1.372 ? g of palmatine hydrochloride.The average recovery of berberine was 98.63 %,RSD being 2.01 %.The average recovery of palmatine was 102.34 %,RSD being 1.67 %.Conclusion This method is simple and quick,and can be used for the quality control of FYXL.
ABSTRACT
Objective To determine the content of emodin in Qinhuang Houzhen Capsule and to provide evidence for its quality criteria.Method A HPLC method was established as follows: Dionex AcclaimTM120 C18 cloumn(4.6? 150 mm,5 ? m),methnol-0.4 % phosphoric acid aqueous solution(85∶ 15) as mobile phase,flow rate at 1.0 mL/min and detection wavelength at 254 nm.Results The average content of emodin in Qinhuang Houzhen Capsule was 0.2057 mg/g,and RSD=4.11 %.Conclusion The content of rhubarb calculated by emodin in 1 g Qinhuang Houzhen Capsule could be affirmed at 0.150 mg/g tentatively.The method is simple,acurate,repeatible,and can be used for the quality control of Qinhuang Houzhen Capsule.
ABSTRACT
AIM: To study the effects of Zhongjingweiling Capsule (Fructus Amomi, Cortex Cinnamemi, Rhizoma Alpiniae Galangae, Fructus Foeniculi, Radix Glycyrrhizae, etc.) on analgesia, anti inflammation and gastrointestinal peristalsis inhibition. METHODS: The effect of analgesia was tested by the method of writhes and hot plate on mice. The effect of anti inflammation was tested by injecting acetic acid and implanting cotton pellet and xylene into mice. RESULT: Zhongjingweiling Capsule effectively inhibited the swelling of mouse pinna induced by xylene and the increase of peritoneal capillary permeability caused by the acetic acid injected into mice. The capsule also decreased the proliferation of granuloma caused by implantation cotton pellet significantly and had an abirritant effect on the algesia induced by acetic acid and hot plate. Besides, it effectively inhibited the gastrointestinal peristalsis. CONCLUSION: Zhongjingweiling Capsule is an effective medicine in anti inflammation, analgesia, and gastrointestinal peristalsis inhibition.
