Study of magnesium,glycosylated hemoglobin and lipid profile in diabetic retinopathy     

Ishrat Kareem  S. A. Jaweed  J. S. Bardapurkar  V. P. Patil 《Indian journal of clinical biochemistry : IJCB》2004,19(2):124-127

The present study was undertaken in 100 subjects, 30 diabetics without complication (group I), 40 diabetics with retinopathy (group II) and 30 non diabetic as normal control group (group III). Blood sugar levels, magnesium, cholesterol and triglyceride were analyzed from plasma and serum. The results were correlated with degree of diabetic control from the levels of glycosylated hemoglobin. Serum magnesium levels in group II were found to be significantly lowered than in group I. There was also significant difference in magnesium levels of group I and group III. We found a significant correlation between the glycosylated hemoglobin and magnesium levels in our study. The results also indicate that the patients with diabetic retinopathy showed significant rise in serum cholesterol and triglyceride. Probably hypomagnesemia and increased serum cholesterol and triglyceride levels are responsible for microvascular changes in diabetes leading to retinopathy. The purpose of this study was thus to gather information about the degree of control of diabetes and magnesium status.  相似文献

Hepatoprotective and Nephroprotective Effect of Curcumin Against Copper Toxicity in Rats     

Emad A. Hashish  Shimaa A. Elgaml 《Indian journal of clinical biochemistry : IJCB》2016,31(3):270-277

Curcumin is a natural anti-inflammatory and antioxidant with several potential health benefits. Although it has been examined in several metals toxicity studies, but its role in the protection against copper toxicity has not been investigated. In this study; the detoxification and antioxidant effect of curcumin were examined to determine its prophylactic/therapeutic role experimentally in rats. Forty albino rats were divided into five groups; control, CuSO₄ (4 mg/kg body weight), curcumin (80 mg/kg body weight), curcumin post-treatment (CuSO₄ for 15 days followed by curcumin for the next 15 days) and curcumin co-treatment (CuSO₄ plus curcumin for 30 days). All rats were treated orally by stomach tube for 30 days/once a day. Changes were observed in hepatic marker enzymes such as: aspartate aminotransferase (AST), alanine transaminase-(ALT), alkaline phosphatase (ALP) and gamma-glutamyltransferase (GGT), besides the serum total protein, urea and creatinine. Concentration of liver and kidney antioxidants such as: catalase (CAT), superoxide dismutase (SOD), reduced glutathione-(GSH) and malondialdehyde (MDA) were measured. An increased in the activities of liver marker enzymes, urea, creatinine and the MDA contents were detected after exposure to CuSO₄. Meanwhile, the activities of serum total protein, hepatic and renal antioxidants were decreased. Changes in all biochemical parameters were alleviated by the post-treatment and co-treatment of curcumin. Our finding suggests that the curcumin showed protective effects on CuSO₄-induced hepatotoxicity and nephrotoxicity.  相似文献   

Violent computer games,empathy, and cosmopolitanism     

Mark Coeckelbergh 《Ethics and Information Technology》2007,9(3):219-231

Many philosophical and public discussions of the ethical aspects of violent computer games typically centre on the relation between playing violent videogames and its supposed direct consequences on violent behaviour. But such an approach rests on a controversial empirical claim, is often one-sided in the range of moral theories used, and remains on a general level with its focus on content alone. In response to these problems, I pick up Matt McCormick’s thesis that potential harm from playing computer games is best construed as harm to one’s character, and propose to redirect our attention to the question how violent computer games influence the moral character of players. Inspired by the work of Martha Nussbaum, I sketch a positive account of how computer games can stimulate an empathetic and cosmopolitan moral development. Moreover, rather than making a general argument applicable to a wide spectrum of media, my concern is with specific features of violent computer games that make them especially morally problematic in terms of empathy and cosmopolitanism, features that have to do with the connections between content and medium, and between virtuality and reality. I also discuss some remaining problems. In this way I hope contribute to a less polarised discussion about computer games that does justice to the complexity of their moral dimension, and to offer an account that is helpful to designers, parents, and other stakeholders. An earlier version of this paper was presented at the ACLA 2006 conference in Princeton, 25 March 2006.  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   

Chips,tags and scanners: Ethical challenges for radio frequency identification     

Dara J. Glasser  Kenneth W. Goodman  Norman G. Einspruch 《Ethics and Information Technology》2007,9(2):101-109

Radio Frequency Identification (RFID) systems identify and track objects, animals and, in principle, people. The ability to gather information obtained by tracking consumer goods, government documents, monetary transactions and human beings raises a number of interesting and important privacy issues. Moreover, RFID systems pose an ensemble of other ethical challenges related to appropriate uses and users of such systems. This paper reviews a number of RFID applications with the intention of identifying the technology’s benefits and possible misuses. We offer an overview and discussion of the most important ethical issues concerning RFID, and describes and examine some methods of protecting privacy. Norman G. Einspruch serves as a consultant to several high-technology companies, one of which is in the RFID components and systems business.  相似文献
