Association of TNF-α, IL-10 and IL-6 promoter polymorphisms in pulmonary tuberculosis patients and their household contacts of younger age group     

《Comparative immunology, microbiology and infectious diseases》2018

Single nucleotide polymorphisms (SNPs) of cytokine genes have been found to be involved in the clinical outcome of Tuberculosis. The present study was aimed to identify the high risk genotypes in Tuberculosis patients and their household contacts. A total of 490 subjects were studied which includes 150 active pulmonary tuberculosis patients (APTB), 190 household contacts (HHC) and 150 healthy controls (HC). The SNPs of TNF-α (-308A/G), IL-10(-1082G/A) and IL-6(-174G/C) were performed by ARMs PCR. The IL-10 GA genotype showed significant association in APTB and HHC and was 2.3 times higher risk in APTB and 3.7 times in HHC compared to HCs. The A allele was found to be significantly associated with the risk of disease. The CC genotype of IL-6 was found to be significantly associated in APTB and an insignificant positive association in HHCs. The multifactor dimensionality reduction (MDR) analysis indicated that the genotypes of IL-6 were showing high risk with GA genotype of IL-10. In conclusion the gene interaction may be useful for identification of genotypes as biomarkers to distinguish high risk individuals.  相似文献

白跗平腹小蜂对主要森林害虫抑制力研究     

方惠兰  廉月琰 《浙江林业科技》1994,14(2):1-3

１９８７～１９９２年连续６年研究结果表明，白跗平腹小蜂Ａｎａｓｔａｔｕｓａｌｂｉｔａｒｓｉｓ对马尾松毛虫Ｄｅｎｄｒｏｌｉｍｕｓｐｕｎｃｔａｔｕｓ、柳杉毛虫Ｄｅｎｄｒｏｌｉｍｕｓｌａｔｉｐｅｎｎｉｓ、水青蛾Ａｃｔｉａｓｓｅｔｅｎｅｎｉｎｇｐｏａｎａ等１３种主要森林害虫卵有较明显的抑制作用。在林间，该蜂对马尾松毛虫第１、２代卵的自然抑制力分别力１６．５５％和２２．２９％，对柳杉毛虫越冬代卵的自然抑制力为２３．４５％；对水青蛾第１、２代卵的抑制力分别力５．４９％和２．６３％；在林间，人为释放白跗平腹小蜂对第１代马尾松毛虫卵的校正抑制力为３３．５％，在室内１２．３～２８℃范围内，每头雌峰对马尾松毛虫、水青蛾和柞蚕剖腹卵的日破坏数（寄生数）分别力１５、１８和２６粒，一生破坏数分别为５６、９１和２０８粒。即使虫卵即将孵化，该峰同样亦能寄生，并羽化出正常的子代白跗平腹小蜂。  相似文献

The effect of some Frescon analogs on the aquatic snail,Lymnaea stagnalis: II. Correlation of neurotoxicity to Molluscicidal effectiveness     

B.L. Brezden  D.R. Gardner 《Pesticide biochemistry and physiology》1980,13(2):178-188

Although the molluscicide Frescon is a strong neurotoxin to the Lymnaea stagnalis central nervous system in vitro, it is probable that the exposure of the whole animal to this molluscicide fails to result in central nervous system abnormalities: Frescon does not appear to reach the brain in sufficient quantity to disrupt its normal activity. However, only those Frescon analogs found to be neurotoxic were molluscicidal, suggesting some related mode, if not site, of action. Frescon and its analogs may act by affecting excitable tissues other than the nervous system (e.g., the snail musculature) by altering certain functional and/or structural membrane properties.  相似文献   

外源Ca²⁺ 和ABA 对高温下黄瓜花药中Ca^{2 +} 、ABA及蛋白质合成的影响   总被引：3，自引：0，他引：3  

缪旻珉  朱月林  张玉华 《园艺学报》2005,32(1):111-114

 外源Ca^{2 +}能降低高温下黄瓜单核期花药的胞内Ca^{2 +}水平并提高花粉萌发率, 而ABA的作用与此相反。外源Ca^{2 +}和ABA处理能显著提高高温下黄瓜花药内源ABA的水平, 并产生新的蛋白质。以上结果表明, 高温下外源Ca^{2 +}可影响黄瓜花药内ABA信号系统, 继而可能改变基因表达, 并获得耐热性;外源ABA亦能影响黄瓜花药内Ca^{2 +}信号系统。  相似文献
