Cardiovascular complications are the major cause of morbidity and mortality in diabetic patients. An attempt has been made
to evaluate the risk factors for coronary heart disease in type II diabetics. In the present study the levels of fasting and
postprandial plasma glucose, total cholesterol, low density lipoproteins, triglycerides were high and the levels of high density
lipoproteins were low in the type II diabetics compared to controls. The markers of free radical induced injury i.e. malondialdehyde
and nitrite/nitrate were high while total antioxidant status a marker for antioxidant protection against reactive oxygen species
was low in diabetics compared to controls. The study therefore suggests the importance of assessing these markers of oxidative
stress and antioxidant capacity along with the other routine investigations in diabetic patients for initiating antioxidant
therapy in addition to primary and secondary preventive measures to mitigate the devastating consequences of diabetes leading
to coronary heart disease. 相似文献

Folate and cobalamin (Vitamin B12) are two essential micronutrients involved in one-carbon metabolism, which affects heart disease, neural tube defects and
cancer. Methylenetetrahydrofolate reductase, the key enzyme involved in one carbon metabolism produces methyl tetrahydrofolate
from methylene tetrahydrofolate, which in turn donates methyl group to homocysteine to generate methionine. There exist two
common low function polymorphic variants of the methylenetetrahydrofolate reductase gene involving nucleotides 677 C→T and
1298 A→C, which are associated with hyperhomocysteinemia. These polymorphisms are also linked with increased risk for certain
cancers such as breast cancer and at the same time providing a protective effect on colorectal cancer. In this case control
study, we have evaluated levels of folic acid, vitamin B12 and homocysteine in patients with colorectal cancer. Folate and homocysteine levels did not differ significantly between
the two groups; however an increasing trend was noticed with increase in homocysteine levels. Vitamin B12 levels were increased in cases compared to control group. 相似文献

In this section of Resonance, we invite readers to pose questions likely to be raised in a classroom situation.Wemay suggest strategies for dealingwith
them, or invite responses, or both. “Classroom” is equally a forum for raising broader issues and sharing personal experiences
and viewpoints on matters related to teaching and learning science. 相似文献
