Nicotine, an active substance present in tobacco has been identified as a major risk factor for lung related diseases. In the present study, we have evaluated the protective effect of curcumin on circulatory lipid peroxidation and antioxidants in nicotine administered Wistar rats. Lung toxicity was induced by subcutaneous injection of nicotine at a dose of 2.5 mg/kg body weight (5 days a week, for 22 weeks) and curcumin (80 mg/kg body weight) was given simultaneously along with nicotine by intragastric intubation for 22 weeks. Enhanced lipid peroxidation (41.68%) in the circulation of nicotine treated animals was accompanied by a significant decrease in the levels of ascorbic acid, vitamin E, reduced glutathione, glutathione peroxidase, superoxide dismutase and catalase. Further, reduction in the levels of zinc and elevation of copper and ferritin were observed in circulation of nicotine treated rats. Administration of curcumin significantly lowered the concentrations of lipid peroxides (36%) and enhanced the antioxidant status with modulation in the levels of zinc, copper and ferritin. Our data suggest that curcumin exerts its preventive effects by modulating the degree of lipid peroxidation, antioxidant status and trace element levels.

The immunoassays methods need avoiding interferences that can influence result interpretation. Main sources of interference arise from either patient status, preparation and physiology or laboratory process and procedures. The aim of this non-systematic critical review is to highlight the preanalytical interferences on laboratory immunoassays. Blood hormone profile changes according with age and depending on sex: these are important variables, mainly in newborn, during both sexual maturation and childbearing. Gonadotropins FSH and LH show a sharp increase with age in females, whereas in males LH appears rather stable. With age both males and females show progressive decay of the hormone profile. Stress causes variations, as it influences GH, prolactin, Cortisol and the total/free ratio of thyroid hormone. Diurnal variations, day of cycle, influence by estrogens on thyroid hormone are relevant for result variability. Paraproteins and autoantibodies can interfere in some assays particularly drug, vitamin D and thyroid hormone. As regards the variables due to sample matrix, and to evacuated tubes components, some additives and anticoagulants have been reported to influence specific assays, e.g. thyroid hormone. Hemolysis, lipemia and bilirubin cause interferences on specific techniques/tests, e.g. ferritin, TSH, Vitamin B12, progesterone and folic acid. Nicotine and cocaine addictions interfere with some hormones. Thus, laboratory professionals should be aware of preanalytical problems particularly important when dealing with the immunoassays, by taking appropriate actions to avoid any relevant interferences.
