China Journal of Traditional Chinese Medicine and Pharmacy 2005;0(04):-
Objective: To research the method of Establishing model of polymyositis with damp-heat syndrome. Methods: 45 guinea pigs were randomly divided into three groups, group A (normal group), group B (experimental myositis group, control group), Group C (damp-heat group). In the control group, the rabbit skeletal muscle homogenate Garver,s complete adjuvant for subcutaneous immunization was used to injecting into the original guinea pigs. Besides the above-mentioned immune method, the heat-damp model method was used (feigan diet, hot and humid environment and pathogenic micro-organisms and other complex factors) to establish the polymyositis model with damp-heat syndrome. The general situations, such as the serum muscle enzymes, light microscopy, electron microscopy changes in each group were observed. Results: The results showed that the clinical performance, serum creatase, the pathological changes of skeletal muscle, lungs, liver of guinea pigs in damp-heat group were similar to the human polymyositis with damp-heat syndrome. Conclusion: The model can be used to study the human polymyositis with damp-heat syndrome, and provide the pathogenic and theoretical basis for treating polymyositis by TCM.

OBJECTIVE: Amyotrophic lateral sclerosis(ALS) is a chronic progressive degenerative disease selectively infringing upper and lower motoneurons, and its pathogeny and pathogenesis are unclear till now. Its researches are mainly relying on animal models. Currently, there are many methods for the establishment of ALS animal.model and each of them has its own characters,practicability and values.DATA SOURCES: Relative articles during the period from January 1980 to December 2003 were searched on the Medline database by the title of the article with the searching word "amyotrophic lateral sclerosis, model" and the language of the articles was limited to English.STUDY SELECTION: Data were preliminarily screened for the selection of the literatures mainly regarding the researches of ALS animal models; and then literatures regarding the application of ALS animal model in medication effectiveness and pathogenesis were eliminated; the full texts of the rest literatures were searched as inclusive criteria.DATA EXTRACTION: Totally 96articles searched with "amyotrophic lateral sclerosis, model" in title were collected. Fifteen tests were in accordance with the inclusive criteria. In the eliminated 81 tests, 75 literatures were about the researches on the application of ALS model for medication observation and pathogenesis research, and the rest 6 articles were repetitive experiments.DATA SYNTHESIS: ALS neurotoxic animal model, immune mediated animal model, spontaneous animal model, and transgenic animal model were established in the selected literatures, which also investigated the mechanism, features, practicability and value of the animal model.CONCLUSION: The establishment of animal models simulated ALS symptoms or pathogenesis in the above literatures can be used in ALS disease researches as referencing model, which could provide animal experimental basis for the researches of ALS pathogenesis and the confirmation of therapy plan.

Objective To investigate the effect of propofol pretreatment on hippocampal monocyte chemotactic protein-1 ( MCP-1 ) and CC-chemokine receptor type 2 (CCR2) expression following forebrain ischemiarepcrfusion (I/R) in rats. Methods Twenty-four male SD rats weighing 250-300 g were randomly divided into 3 groups ( n = 8 each): group Ⅰ control; group Ⅱ I/R and group Ⅲ propofol pretreatment. Cerebral I/R was induced by clamping bilateral common carotid arteries for 10 min combined with hypotension ( MAP was maintained at 35-45 mm Hg) induced by exsanguinations in group Ⅱ and Ⅲ. In group Ⅲ propofol 50 mg/kg was injected into femoral vein immediately before cerebral ischemia. The animals were sacrificed at 6 h of reperfusion. Hippocampal tissue was obtained for detection of MCP-1 mRNA and CCR2 mRNA and their protein expression by RT-PCR and Western blot technique. Results I/R significantly increased the expression of MCP-1 and CCR2 in hippoeampal tissue as compared with control group. Propofol pretreatment significantly attenuated cerebral I/R induced increase in MCP-1 and CCR2 expression. Conclusion Propofol pretreatment can significantly inhibit forebrain I/R-induced hippocampal MCP-1 and CCP2 expression.
