Serious health problems in humans are caused by arsenic-exposure, which is wide spread in the environment. Sodium arsenite, capable of inducing macromolecular damage is evaluated for its DNA damaging effect in the blood, liver, kidney and bone marrow cells of Wistar rats. Also the ameliorative potential of a-tocopherol (400 mg/kg body weight) and ascorbic acid (200 mg/kg body weight) supplemented orally to arsenic-intoxicated rats (100 ppm in drinking water for thirty days) in neutralizing the genotoxic effect of arsenite was explored. Detection of DNA damage at cellular level is evaluated by single cell gel electrophoresis or comet assay, under alkaline conditions. This study demonstrated that dietary supplementation of antioxidants such as vitamins C and E could ameliorate arsenite induced toxicity in experimental rats.Keywords

In this study the Ultrasonic velocity and density of different proportionate mixture of Lithium Hydroxide (LiOH) and Lithium Sulphate (Li2SO4) are determined in the frequency range of 3MHz at room temperature using ultrasonic interferometer technique. With the values of velocity and density, the parameters like adiabatic compressibility, inter molecular free length, acoustical impedance, molar sound velocity, molar compressibility and molar volume have been calculated. It is observed that there is a complex nature of the mixture at a particular definite concentration.Full Text

The Ultrasonic velocities, Density and viscosity of cholesterol in chloroform solutions for varying concentrations have been measured at 294 K. From these data, Isentropic compressibility (Ks), Intermolecular free length (Lf), Molar volume (V), Molar sound velocity(R), Molar compressibility (W), Relaxation time (t), Relative association (RA), Free volume (Vf) and Degree of molecular interactions (α) have been calculated. These parameters are used, to explain the nature of interaction between the chloroform and cholesterol molecules of the mixtures. The variation of ultrasonic velocity shows a dip at a concentration of 9%. It is observed that the complex formation between unlike molecules occurs at the concentration of 8% and 9%. Sound velocities were evaluated based on Free Length theory and Nomoto's relation and gives good agreement with the experimental values for the system studied. Non-ideality in the liquid mixtures has been discussed in terms of U2exp/U2imix where Uexpand Uimix are the experimental and ideal mixture velocities respectively.Full Text

Ultrasonic study of mixture of ammonium sulphate and ammonium chloride in water at different concentrations have been carried out at a frequency of 2 MHz and at 303 K. Using the ultrasonic velocity and density, adiabatic compressibility, intermolecular free length, acoustic impedance have been calculated. The graph between ultrasonic velocity (U) and mole fraction (Cm) of ammonium sulphate in the mixed solution shows dips at a composition of 60:40 . The observed variations with different composition of the mixture are discussed.Full Text

Aim: To find the effect of a combined exercise intervention namely Brandt-Daroff exercise (BDE) combined with Cawthorne Cooksey exercises (CCE) for treatment of vertigo among posterior canal benign paroxysmal positional vertigo (BPPV) subjects. Materials and methods: A total of 20 male and female subjects in the age group of 25-45 years were included if they were diagnosed with posterior canal benign paroxysmal positional vertigo. The recruited subjects were randomly divided into two groups. Group A (Experimental group) n=10 subjects received both BDE and CCE and Group B (Control group) n=10 subjects received only BDE. Results: The statistical analysis shows that both groups have significant improvement in their symptoms. Group A has greater improvement than Group B which is statistically significant. Conclusion: This study concludes that addition of Cawthorne -Cooksey habituation exercises along with Brandt-Daroff exercises is more effective in treatment of vertigo among posterior canal BPPV subjects.Keywords
