Effect of cedemex on cAMP and cGMP levels of different brain areas in morphine withdrawal rats / 中国中药杂志

<p><b>OBJECTIVE</b>To investigate the effect of Cedemex on cAMP and cGMP contents in different brain regions in morphine withdrawal rats precipitated by naloxone.</p><p><b>METHOD</b>A physical morphine dependent model of rats was established by subcutaneous injection of morphine in gradually increasing dosage within 7 days. cAMP and cGMP contents of VTA, cortex and hippocampus of the rat brains were determined by radioimmunoassay.</p><p><b>RESULT</b>The morphine withdrawal symptoms of rats were relieved significantly by ig Cedemex. Compared with the controls, cAMP content in the region of VTA, cortex and hippocampus of the morphine dependent rats were significantly higher (P < 0.05), while cGMP contents in those regions were significantly lower (P < 0.05). cAMP contents in the area of VTA, cortex and hippocampus of the morphine dependent rats were significantly reduced, while cGMP contents were significantly increased by ig Cedemex.</p><p><b>CONCLUSION</b>Cedemex may significantly attenuate the morphine withdrawal symptoms in rats. The mechanism of this effect may be related to adjusting the contents of cAMP and cGMP in some brain regions.</p>

HLA-DQA1 genotyping by PCR-SSP technique in Jing nationality of Central Vietnam / 中国免疫学杂志

Objective:To investigate the polymorphism of HLA-DQA1 genes in Jing nationality of Central Vietnam.Methods:Applied PCR-SSP tecnique to determine the polymorphism of the HLA-DQA1 alleles of 105 healthy children and youth,unrelated individuals in Central of Vietnam.Results:10 HLA-DQA1 alleles were detected of which DQA1*0104 were the most common allele with frequency of 21.3% and lowest frequency is DQA1*0601.Conclusion:The results indicate that HLA-DQA1 alleles polymorphism of Jing nationality in Central Vietnam is different from the other Chinese.
