Abstract: Background: Nerve conduction velocity is being used as a widespread measure of diagnosis of nerve function abnormalities. Dependence of nerve conduction parameters on intrinsic factors like age and sex, as well as extrinsic factors like temperature is well known. Lateralization of various cerebral functions like speech, language, visuospatial relations, analysis of face, recognition of musical themes and use of hand for fine motor movements have also been studied. The aim of this study is to compare the nerve conduction velocity of different subjects with different height using median nerve and find out whether there is any difference in relation between motor nerve conduction velocity and height. Method: The study was carried out in students of B J Medical College by the use of standard 2 channel physiograph. Comparison of motor nerve conduction velocity between subjects of different height was done under equation of Pearson correlation. Result: There are several factors which affect nerve conduction velocity. Some skills like music, sports activities are also due to hemispheric difference. Age and sex affect nerve conduction velocity. Here we compare the relation between height and motor nerve conduction velocity. On comparison of motor nerve conduction velocity of median nerve with different height of the subjects the study shows that there is significant decrement in nerve conduction velocity with increase in height of subjects. Conclusion: From the results we can conclude that there is inverse correlation between height and nerve conduction velocity of subjects.

Abstract: Backgrounds and objectives: Excessive noise pollution is a worldwide occupational health hazard which has considerable social, psychological and physiological impacts, including noise induced hearing loss (NIHL) at higher frequencies. Whilst occupational noise induced hearing loss is entirely preventable if measures are taken, once acquired it is irreversible. Our aim was to evaluate and compare the Auditory functions in subjects exposed to noise with unexposed once (control groups) and to find out the correlation between duration of exposure with observed audiometry parameters. Method: Study was done in 100 food industry workers of them 50 were exposed to noise and remaining 50 were not. Pure tone audiometry was done in all of them and the data obtained was analyzed by Epi info software. Result: It is found that those who were exposed to noise had higher hearing threshold than control with significance. Conclusion: Most food and drink industries have processes which emit high noise levels exceeding the 80dB (A) and 85dB (A) levels which affect their hearing sense adversely, so measures need to be taken to prevent it.

Abstracts: Background and Objectives: Chronic hypertension has been found to be associated with altered Pulmonary Function Tests (PFTs). However, alteration in PFTs and their association with antihypertensive drugs has not yet been established. Therefore, the present study was undertaken to find out relationship altered PFTs in hypertensive patients on an antihypertensive drugs for more than one year. Methods: Hypertensive patients were taken from OPD of Quresh Medical Trust, Ahmedabad and further divided into 2 groups, case group (n=50) those who were taking antihypertensive drugs for more than one year and control group (n=50) those who were not taking any antihypertensive drugs. PFT parameters (FVC, FEV1, PEFR & MVV) were studied in both the groups by using spirometer (Computerised Spirometer GMS-HELIOS 702).Results: The findings of Pulmonary Function Tests showing that FVC,FEV1, PEFR & MVV all were reduced in case group compared to control group and the difference was statically significant (p<0.01)Interpretation & Conclusions: Similar to earlier studies done in India and abroad we also found an impairment of the lung functions in hypertensive patients taking long term antihypertensive drugs especially Beta blockers1 . So, the antihypertensive drugs should chose according to the status of the individual patients. Antihypertensive drugs (Thiazide diuretics, calcium channel blockers, newer beta1 blockers) which have less effect on airway functions are the drug of choice in hypertensive patients having airway dysfunction.2
