Background: Thyroid hormones plays an important role in control of metabolism in human. Hyperlipidaemia particularly hypercholesterolemia, is a well-documented significant health consequence associated with hypo-thyroidism. Oxidative stress is a common factor associated with several clinical conditions including hypothyroidism. Aims & Objective: To evaluate the association between BMI, Hyperlipidaemia, Lipid Peroxidation and Atherogenic risk in newly diagnosed hypothyroid patients. Material and Methods: 85 newly diagnosed hypothyroid cases and 41 euthyroid controls were studied for their Thyroid profile [TSH, T4 andT3], Lipid profile , Oxidative stress marker, Malondialdehyde {MDA} Lipid risk ratios, [TC/HDL-C and LDL-C / HDL-C ratio] , Atherogenic index [AIP] - log TG/HDL-C and Body Mass Index [BMI]. Results: Hypothyroid patients had hyperlipidaemia, especially hypercholesterolemia [224 ± 43.8 mg/dl], increased LDL-C level [150.4 ± 42.3 mg/dl] when compared to controls [169.5 ± 25.1 and 97 ± 25.5 respectively]. MDA was significantly increased [p< 0.0001] in hypothyroid subjects [6.14± 1.83μ mol/L] versus the controls [2.9 ± 0.86 μmol/L] .BMI had positive correlation with TSH [r =4.421; p<0.0001]. Conclusion: Hypothyroidism leads to hyperlipidaemia enhancing risk for cardiovascular diseases, the connecting link being oxidative stress. It was found that TSH had positive significant correlation with BMI, Lipid profile and oxidative stress in hypothyroid patients when compared to the controls making them more prone for coronary artery diseases.

The Vero cell culture adapted buffalo pox virus was found to be completely attenuated at 40th passage for rabbits as well as buffaloes since it did not produce any thermal reaction or skin lesions. It induced high level of humoral and cell mediated immune response in rabbits as well as buffaloes. The antibody titres obtained were 80-160 for SN antibody, 32 for complement fixing and 640-1280 for enzyme immunoassay antibodies. The percent migration inhibition (MI) of leukocytes was 65.3% in rabbits and 69.50% in buffaloes, MI of macrophages was 62.15% in rabbits and 63.02% in buffaloes with a high skin reactive factor value. In protection tests conducted in rabbits and buffaloes, all the vaccinated animals were immune as compared to controls which showed severe disease.
