Correlative study between neuron-specific enolase and blood sugar level in ischemic stroke patients

Background: A study to investigate the level of the neurobiochemical marker, Neuron-Specific Enolase (NSE), at the time of admission and its correlation with the blood sugar level in ischemic stroke patients. Patients and Methods: We investigated 90 patients with complete stroke who were admitted to the Stroke Unit of the Department of Neurology at Sri Aurobindo Institute of Medical Sciences. NSE was measured with commercially available quantitative ‘sandwich’ enzyme-linked immunosorbent assay kits obtained from R and D Systems. Hyperglycemia was defined as blood glucose concentration ≥ 7 mmol / L, and measured using the glucose oxidase method immediately. Results: Significantly increased NSE and lipid profile levels were found in ischemic stroke patients as compared to the control. Hyperglycemic ischemic stroke patients had increased levels of NSE, lipid profile, and National Institute of Health stroke scale scores (NIHSS score) compared to normoglycemic ischemic stroke patients. In addition the serum NSE level of hyperglycemic stroke patients was also positively correlated with the blood sugar level (r = 0.734 P < 0.001). Conclusions: Hyperglycemia predicts an increased risk of poor outcome after ischemic stroke and it is reflected by a significantly increased level of Neuron-Specific Enolase.

A Study of Serum Malondialdehyde and Cytokine in Tuberculosis Patients

INTRODUCTION Tuberculosis (TB) is a common and a deadly infectious disease which is caused by Mycobacterium tuberculi. Inflammatory cytokines play an important role during the course of the disease and they may be responsible for tissue damage which is caused by lipid peroxidation. METHOD The present study was conducted in the Department of Biochemistry and patients were selected from Department of TB and Chest Sri Aurobindo Institute of Medical Sciences and also from Manorama Raje Tuberculosis Hospital, Indore. 32 healthy controls and 35 pulmonary TB patients were compared initially for their serum Malondialdehyde (MDA) and tumour necrosis factor alpha (TNF α) levels. Serum TNF α and MDA levels were correlated. RESULT TNF α and MDA levels in serum were significantly increased (p<0.001) in pulmonary tuberculosis patients as compared to those of controls. Increased Serum TNF α was positively correlated to MDA levels and it was found to be statistically not significant (correlation coefficient r =0.282,p> 0.05 ). CONCLUSION The present study supports the view that there may be a link between lipid peroxidation and cytokine response and relative roles of cytokines and lipid peroxidation in the pathogenesis of tuberculosis.
