Chinese Traditional Patent Medicine 1992;0(10):-
AIM: To establish a method for determination of schizandrol A in Mian'er'an Dripping Pills (Semen Ziziphi Spinosae, Fructus Schisandrae, etc.). METHODS: HPLC was used with hypersil C 18 column (250mm?4.6mm; 5?m), methanol water (65∶35) as a mobile phase and detection wavelength at 254nm. The flow rate was 1.0mL?min -1 and at room temperature. RESULTS: The calibration curve was linear (r= 0.9999). The average recovery was 100.2% and RSD was 2.9%, respectively. CONCLUSION: The method is simple, quick and specific, and provides a quality control for the dripping pills.

Lappaconitine (LA) 0. 5 mg? kg-1had significant antagonistic action on the ar-rythmia induced by 3-acetylaconitine ( AA ) 0.07 mg?kg-1in rat. When LA and AA were used in combination (7:1) in mice, the analgesic activity of AA was not influenced marked-ly by LA but the LD50 of AA was increased by 50% ,therefore the therapeutic index of AA was increased and the margin of safety was widened.

The construction of the model curricula is the important branch of teaching quality engineering. The key to the development of the model curricula lies in the reform of the teaching model. As required to the national standards of the model curricula and to the purpose of innovative educational philosophy,with the years of continuous exploration and practice,the clinical immunology examination curriculum has kept developing from the teaching staff,teaching condition,content of course,teaching method and means etc.,which has brought about satisfactory teaching effects. Thus it is forming the model curricula with special features.

ObjectiveTo investigate the protection of extract form earthworm a traditional Chinese medicine in auricle microcirculation disturbance in mice. MethodThe microcirculation disturbance in mice was brought by rapid injection of high molecule dextran. Observe the microvascular diameter,the blood flow speed,the blood fluid state and crossing net patency quantity of micrangium in mice before injection and after injection 10min,20min,30min with WX-9 microcirculation microscope and analytical system. ResultHigh and low dose of extract form earthworm could expend the diameter of the vein and artery of micrangium, quicken the blood flow speed,improve the blood fluid state,increase micrangium crossing net patefaction numbers. To compare with the control group, threr’s significant difference (P

Objective:To investigate the pain in patients during the early stages of recovery from maxillofacial surgery under general anaesthesia.Methods: One hundred patients as participants to respone the questionaire of postoperative pain 24 hours after operation. The data of pain intensity,analgesia requirement and the reason for operation of the patients were collected and analyzed. Results: Among the 100 cases, 92 with moderate or slight postoperative pain, 8 with severe pain. It is significant more severe pain (14.3%)in the group of bone fracture than that (less than 8.7%) in other groups. Conclusion: Most patients 24 h after maxillofacial surgery are with moderate and slight pain. The pain intensity relates with type of maxillofacial surgery.

Objective To investigate the relationship between renin (REN) gene G10631A, angiotensinogen (AGT) gene T704C mononucleotide polymorphisms and cerebral infarction and to investigate the mechanisms and characteristics of cerebral infarction from molecular level. Methods REN gene G1063A and AGT gene T704C polymorphisms in 82 patients with cerebral infarction and 89 controls were detected with polymerase chain reactionrestriction fragment length polymorphism. The differences of the genotypes and allele frequencies were compared between the patient group and the control group. Results The frequency of REN 10631AA genotype (31. 7% vs. 10. 1%,χ2 =12. 816, P = 0. 002) and the frequency of A genotype (49. 4% vs. 30. 3% χ2 = 12. 969, P =0. 000), as well as the frequency of AGT 704 CC genotype (63. 4% vs. 34. 8% χ2 = 15. 029, P = 0. 001) and the frequency of A genotype (79. 9% vs. 61. 2% χ2 = 14. 173, P = 0. 000) in the cerebral infarction group were all significantly higher than those in the control group; the frequency of haplotype 704C 10631A was also significantly higher than that in the control group (P=0. 000). Conclusions REN 10631AA genetype and A allele as well as AGT 704 CC genetype and C allele may be the susceptible factors of cerebral infarction. Haplotype 704C-10631 A may be a genetic risk factor for the occurrence of cerebral infarction.

A polymer film of vitamin B1 was obtained at a graphite carbon electrode by cyclic voltammetric method in phosphate buffer solution (PBS). Cyclic voltammograms of the film electrode in PBS (pH 5) exhibited one pair redox waves, Epa=350 mV,Epc=325 mV,different from monomer vitamin B1. The peak currents of poly-VB1 films was proportional to (scan rate)1/2, which showed that the charge transfer was controlled by diffusion in the polymer film. The Poly-VB1 modified electrode showed a good catalytic ability to dopamine and epinephrine. At the modified electrod, the peak potential for oxidation of dopamine occurred at 250 mV and 200 mV for epinephrine, while they were shifted towards the negative direction 100 mV and 300 mV respectively at the bare glassy carbon electrode . And their peak current had a linear relationship to the concentrations in the range of 8.0×10-7~1.0×10-4 mol/L for dopamine and 1.0×10-6~1.0×10-4 mol/L for epinephrine.
