噪声应激对血压及心率变异性的影响     

胡军祥  杨琼霞  黄佩龙  朱栋奎  姜玉新 《科技通报》2007,23(5):681-683,740

对被试者分别进行80dB和100dB的噪声刺激，并在第1、5、10、15和20d测定被试者的动脉血压和心电图，并分析心率变异性变化。实验结果表明：噪声应激使被试者的收缩压升高，心率加快．但对舒张压影响不明显，心率变异性频谱分析显示，高频成分、低频成分增大，而R-R间期减小，而且100dB的作用比80dB显著。提示噪声应激对人体心血管系统的活动有明显的影响。  相似文献   

Myeloperoxidase in Chronic Kidney Disease     

Madhusudhana Rao A  Anand U  Anand CV 《Indian journal of clinical biochemistry : IJCB》2011,26(1):28-31

Numerous lines of evidence implicate a role of myeloperoxidase (MPO) in the pathogenesis of cardiovascular disease (CVD). It is a well accepted fact that patients with chronic kidney disease (CKD) are at an increased risk for CVD. MPO is a pro-oxidant enzyme which could be involved in the increased susceptibility of these patients to CVD. Hence, the levels of plasma MPO was determined in healthy controls as well as in patients with CKD [stratified with the level of their kidney failure as CKD stages II–V (end stage renal disease)]. Plasma MPO was assayed by a spectrophotometric method. Serum urea and creatinine were estimated on a clinical chemistry analyzer using standard laboratory procedures. The mean plasma MPO levels were significantly lower with advancing stages of renal failure (P < 0.001). There was a positive correlation between MPO and GFR (r = +0.89, P < 0.001) and a negative correlation with urea (r = −0.85, P < 0.001) and creatinine (r = −0.82, P < 0.001). While an inverse association was observed between plasma MPO and urea in CKD patients, such an association was not observed in control subjects (P = 0.43). In conclusion, the decline in plasma MPO levels may be due to the inhibitory effect of uraemic toxins on the enzyme.  相似文献   

Assessment of oxidative stress and antioxidant status in age related cataract in a rural population     

A. K. Pradhan  A. K. Shukla  M. V. R. Reddy  N. Garg 《Indian journal of clinical biochemistry : IJCB》2004,19(1):83-87

Oxidative stress was assesed by estimating lipid peroxidation product (LPO) in the form of thiobarbituric acid reactive substances (TBARS), enzymatic antioxidants in the form of superoxide dismutase (SOD), catalase and nonenzymatic antioxidant vitamins e.g. vitamin C, β carotene and vitamin E in either serum or plasma or erythrocytes in 190 cases of age related cataract in the age group of 50–80 years. 190 cases were grouped into three morphological types namely, 73 cases of cortical, 77 cases of posterior subcapsular and 40 cases of nuclear cataract and values of LPO and antioxidants were compared with 78 cases of age matched healthy control groups. Plasma TBARS levels were cataract cases when compared with control groups. There were no significant differences in the erythrocyte levels of catalase and plasma levels of Vit E between cataract cases and control groups. No significant changes of parameters were seen among three different morphological types of age related cataract. The present study shows that the oxidative stress may play an important role in the age related cataract.  相似文献

水分胁迫对黄淮海夏玉米农业气候资源利用的影响——水分胁迫对叶片生产力影响   总被引：2，自引：0，他引：2  

刘建栋  李世奎  于强  闵庆文  毕建杰 《资源科学》2002,24(1)

文章对水分胁迫的夏玉米光合生产力变化进行了系统观测和实验 ,研究表明 :①可将土壤持水量的 4 0 6 89%～ 5 5 79%和 79 99%作为叶片缺水及最适的外部形态指标 ;②干旱可以使株高低 2 2 5 6 %左右 ,而短时间内水分一直维持在田间持水量水平 ,对玉米的株高影响并不大 ;③比叶重随土壤湿度增加而增大 ,到田间持水量的 79 9%时达到最大值 ,随着湿度的进一步增加 ,比叶重反而略微变小 ;④叶片含水量与土壤湿度成正相关 ,吸收辐射率则受叶片湿度与厚度的影响 ,当土壤湿度达到持水量的 79 99%时 ,叶片吸收辐射率可达到 80 %左右。在此研究基础上 ,给出了包含浓度、辐射强度、温度及土壤水分因子的夏玉米叶片生产力计算公式 ,为进一步准确推算水分胁迫对区域生产力的可能影响 ,为当地政府开发农业气候资源提供了前提条件。  相似文献

Experimental therapeutic intervention with alpha tocopherol in ethanol induced testicular injuries in rats     

M. Maneesh  Sanjiba Dutta  Amit Chakrabarti  D M Vasudevan 《Indian journal of clinical biochemistry : IJCB》2007,22(1):138-142

Infertility is well-established harmful effect in chronic alcoholism and so far, there is no effective treatment for this condition. The study was conducted to determine the effects of alpha tocopherol on ethanol induced testicular injuries in male albino rats of Wistar strain. Five groups (n=6) of animals were used. Group I served as control. Group II received daily 1.6g ethanol/kg body weight/day for 4 weeks orally. Group III received 1.6g ethanol+80mg alpha tocopherol/kg body weight/day for four weeks orally. Group IV received 1.6g ethanol/kg body weight for/day 4 weeks and followed by 80mg alpha tocopherol/kg body weight/day for four weeks orally. Group V received 1.6g ethanol/kg body weight/day orally for 4 weeks, followed by 4 weeks abstinence. Twently-four hours after the last treatment the rats were sacrificed using anesthetic ether. Testes were removed and used for the estimation of extent of lipid peroxidation and tissue levels of antioxidants and steroidogenic enzymes. Alpha tocopherol treatment increased the activities of testicularΔ ⁵, 3β-HSD. Moreover, the treatment was also associated with significant decrease in testicular oxidative stress. Ethanol-induced oxidative stress and decreased steroidogenesis can be reversed by treatment with alpha tocopherol.  相似文献
