RESUMO
Lipids are of one of the four basic types of molecules of life and its derivatives serve diverse functions in the body. Generally acclaimed functions of lipids include shock absorption and insulation, and energy storage of the body. Phospholipids and cholesterol form the integral part of cell membrane. In addition cholesterol serves as the precursor for bile salts, male and female sex hormones, vitamin D and adrenocortical hormones. Complex lipids consist of neutral lipid core of cholesterol esters and or triacylglycerol and proteins are the chylomicrons, VLDL, LDL and HDL which serve as the carriers of fats, fatty acids and other lipids in the body. Complex lipids are tightly controlled in the body. Its dysregulation has been mainly linked to obesity, diabetes and insulin resistance though the issue is yet to be clearly understood. The present review evaluates recent reports in this regards and try to explain the relationship between dyspidemia and insulin resistance.
RESUMO
Background & objective: Stroke is a dreadful health hazard all over the world as well as in our country and one of the leading causes of mortality & morbidity. The relationship between serum C-reactive protein (CRP) level and post stroke outcome is not well studied especially in Bangladesh. We were interested to study this relationship in our country. Materials & methods: A cross sectional prospective study was performed on 50-stroke patients. Serum CRP & Lipid profile was determined. Post stroke outcome was measured by modified ranking scale (good outcome, score within 0 – 2 & bad outcome, score within 3 – 6). The subjects were divided in two groups, CRP level above or below 10 mg/L. Statistical analysis was performed by using SPSS software. Chi-square test & Spearman’s rho correlation test was done to see the level of significance. Results: Mean serum CRP level was 9.69 mg/L that was higher than normal subjects. Correlation analysis between serums CRP level of stroke patients with post stroke outcome was found to be positively correlated (r = 0.598/p<0.01). Conclusion: Serum CRP level may be used as a prognostic marker in stroke patients and it helps to make necessary management plan to physician.
RESUMO
Metabolic syndrome and insulin resistance has been the subject of much debate over the last two decades. Its pathophysiologycal basis, however, still remains to be clearly understood. Both genetic and environmental factors have been implicated in its pathogenesis. Mutation of genes encoding signal transduction molecules of insulin and acquired factors like aging, diets, physical activity, obesity and related molecular changes, dyslipidemia, hypertension and smoking were proposed by many groups. This review examined both acquired and genetic factors and discussed model of hormone-receptor-postreceptor interactions to explore the molecular basis of insulin resistance.
