Abstract:
Context: Dyslipidemia and hypertension are the commonest risk factors for coronary artery disease (CAD). Persons with combination of risk factors are particularly at high risk of CAD. There is also pronounced influence of blood pressure on the rate of atheroma formation in human subjects. Isolated systolic hypertension commonly seen in elderly subjects can be attributed to atherosclerosis induced stiffening of aorta and major arteries. Aim: This study was therefore carried out 1.To know abnormal lipid profile prevalence and pattern among hypertensive patients and 2.To know association between hypertension and dyslipidemia in our population. Materials and Methods: The present study was carried out on a total of 50 hypertensive patients attending our tertiary care Hospital and 50 age and sex matched healthy controls. Twelve hour fasting lipid analysis was done for Serum triglycerides(TG), total cholesterol(TC), HDL, LDL, VLDL, TC/HDL, Lp(a)&CLTI. Lipid fractions were tabulated according to NCEP/ATP III new guide lines. Statistical analysis was done by t test, Z test and Chi square test. Results and conclusions: Over all mean lipid levels of TC, LDL, Lp(a), TC/HDL >4.5, showed statistically significant association with cases compared to controls. No significant association was noticed in HDL levels between cases and controls. Mean lipid levels with respect to sex, showed abnormalities in TC, Lp(a) and TC/HDL, CLTI more in hypertensive males compared to females as well as controls. Elevation of TC and decrease in HDL was found as the severity of hypertension increased. The commonest individual lipid fraction abnormality was low HDL in 74% followed by elevated total cholesterol in 52%. Next commonest being TC/HDL >4.5 in 50%, followed by elevated Lp(a) in 36%. Commonest lipid abnormality was abnormal TC/HDL>4.5& elevated TG together in 86%. Over all prevalence of all forms of dyslipidaemia was 90%
Key Messages:1.Elevated TC, LDL, Lp(a), TC/HDL >4.5, are significantly associated with hypertension and we must consider primary and secondary prevention with life style modification and drug therapy in hypertensive patients.2.There is no significant association between HDL levels and hypertension.3.Commonest lipid abnormality is abnormal TC/HDL& elevated TG together in 86% and over all prevalence of all forms of dyslipidaemia is 90% (too high). 4.Abnormalities in lipid profile antedate the occurrence of stage I hypertension, therefore it is advisable to recommend lipid profile as screening of asymptomatic prehypertensive patients.
Key words: -Hypertension, Dyslipidaemia, HDL, LDL, VLDL, TC/HDL, Lp (a), CLTI.

Abstract:- A reversed phase ultra performance liquid chromatography (UPLC) method was developed and validated to determine plasma levels of vincristine and quercetin simultaneously. Vincristine, quercetin and apigenin (internal standard) were extracted from plasma by liquid-liquid extraction with ethyl acetate. UPLC analysis was carried out at 25 ºC with a Waters AcQuity UPLC BEH C18 2.1 x 50 mm, 1.7 μm column with the gradient elution of water/formic acid (99.9:0.1, v/v) and acetonitrile/formic acid (99.9:0.1, v/v). The flow rate was 0.5 mL/min and the injection volume was 1 μL. Vincristine and quercetin were detected at wavelengths of 297 nm and 376 nm, respectively, with elution time of 1.45 and 1.13 minutes. The calibration curves were linear from 0.156 to 50 μg/mL for vincristine (r2=0.999) and 0.075 to 6.0 μg/mL (r2=1.000) for quercetin. The coefficients of variation (CV) for the intra- and inter-day assays were below 15.5%. The lower limit of quantitation for vincristine and quercetin in plasma were 0.1 μg/mL and 0.02 μg/mL, respectively. Absolute recoveries ranged from 103.2% to 104.8% for vincristine and 96.7% to 120.0% for quercetin. Both drugs were stable for 24 h at 4ºC. This method was successfully applied to determine plasma vincristine, quercetin metabolites and quercetin levels after intravenous administration in mice.
Key words :- Pharmacokinetics, quercetin, UPLC, vincristine.

Abstract:- Schwannoma of head and neck region are common accounting for 25%. The thyroid gland is an infrequent and rare site for the occurrence of Schwannoma. These tumors often mimic a thyroid nodule. A case of Schwannoma of thyroid gland was diagnosed on histopathological examination.
Key words :- Thyroid gland, benign tumor, Schwannoma, nonepithelial origin.

Abstract:-The occurrence of both obesity and asthma has increased among people over the last several decades. Former data on the association between obesity and asthma has been inconsistent. This study aimed to examine the association of obesity with total IgE levels in south Indian asthma subjects. The serum IgE level was examined in 75 asthma patients and their severities of asthma were determined by pulmonary function tests. Serum IgE level was compared with the severity of asthma and Body Mass Index. Total serum IgE levels significantly increased in obese and asthma groups when compared to control subjects (p<0.005). The data indicated a significant positive correlation between IgE levels and body mass index (BMI) in asthmatic patients (mild P<0.009, moderate P<0.021 and severe asthma P<0.010). The present study suggests that the serum IgE level may reproduce the severity of bronchial asthma. The evidence for the relationship between obesity and asthma is not conclusive however the study finds a positive association between obesity and asthma among south Indian asthmatic subjects.
Key words:-Asthma, BMI, total IgE, obesity, south India.

Abstract:- Two spectrophotometric methods are presented for the determination of a ternary mixture containing chlorpheniramine maleate, diclofenac sodium and paracetamol in combined dosage form without prior separation. The first method is the derivative ratio spectra zero crossing method (DRSZ) where chlorpheniramine maleate, diclofenac sodium were determined by measuring the DD1 amplitudes at 246.7nm, 290.2 nm and paracetamol was determined by measuring the DD1 , DD2 and DD3 amplitudes at 252.8nm, 246.3 nm and 254.3 nm , respectively. The second method is the double divisor ratio spectra derivative method (DDRD) where diclofenac sodium was determined by measuring the DD1 , DD2 at 311 nm and 307 nm, respectively and paracetamol was determined by measuring the DD1 , DD2 and DD3 amplitudes at 253.7nm, 247.9 nm and 253.8nm , respectively. The methods were linear over the concentration range 20-100 μgml-1 chlorpheniramine maleate, 5-40 μgml-1 diclofenac sodium and 2-18 μgml-1 paracetamol. The described methods are rapid , accurate, simple and precise and can be used for quality control of such mixture.
Key words:-Chlorpheniramine maleate, diclofenac sodium, paracetamol , ternary mixture , derivative ratio, double divisor derivative ratio.
