Ventilatory function tests provide a better understanding of functional changes in the lungs and they are significant from the viewpoint of diagnosis, so factors contributing to their variation within the population need to be identified, assessed and the appropriate allowances made. There have been reports on the variations of PEFR with anthropometric determinants, however, data regarding study of PEFR with various anthropometric factors in different age groups is lacking. AIMS: The present study was therefore done to observe the "Correlation of peak expiratory flow rate with anthropometric determinants in healthy adult male population of Haryana". MATERIAL AND METHOD: Peak expiratory flow rate was measured using mini Wright peak flow meter in 150 healthy subjects of same socioeconomic status. The correlations of PEFR with Age, height, weight and chest circumference were calculated in healthy younger (20-34yrs) and older (35-49yrs) adult males. STATISTICAL ANALYSIS: The obtained data were analyzed statistically with the help of IBM SPSS VERSION.20. RESULT: In this study the mean PEFR was found to have statistically significant (p≤ 0.05) positive correlation with the height, weight and chest circumference in younger males whereas noticeable fluctuations were observed in their older counterparts. Maximum values of PEFR were attained in the age group of 25-29yrs after which it showed a declining trend with advancing age. CONCLUSION: PEFR correlates more with height, weight and chest circumference in young adult males than in older males. Respiratory function indices collected from healthy young adult males may be more reliable and predictable than those from older ones.

INTRODUCTION:There is a clear relationship between the amount of cigarette smoked and mortality. Ironically there is also an increased incidence of cigarette smoking in women all over the world with an increased risk of spontaneous abortion in pregnant women. Although exposure is small as compared with that experienced by mainstream smokers, non-smoking passive smokers, who are in the same room may show pulmonary deposition of smoke particles as well as increased blood levels of nicotine and carboxyhaemoglobin, which became dangerous for infant and children. Smoking cessation is usually associate with improvement of lung functions, that can returns to normal over a period of time. AIMS: To compare the efficiency of lung function in active smokers, passive smokers and after cessation of smoking. MATERIALS AND METHODS: 200 subjects with various age groups ranging from less than 20 years upto 60 years, selected from the relative and attendants of patients attending the outpatient department and indoor wards. They were divided into study and control group. Their lung functions were tested by spirometry with the help of Medispiror. The results obtained were analyzed statistically. STATISTICAL ANALYSIS: the statistical analysis was done by using the formulas of two tail t test. RESULT: There is a highly significant (p<0.001) reduction in pulmonary function parameters in smokers as compared to non-smokers and quitters. Among the pulmonary function parameters the mean forced expiratory flow rates are significantly (respectively p<0.05, p<0.01) less in quitters as compared to non-smokers but FVC, FEV1, PEFR. FEF25-75 are not reduced significantly (p>0.05). CONCLUSION: All the pulmonary functions get worse because of smoking and even passive smoking, which can come back to normal (as in non-smoker) after cessation of smoking, which is a true fact for both the genders.

INTRODUCTION:Stress is a dangerous and significant problem of World, which affects physical, mental, behavioral, and emotional health. Yoga has been reported to control stress, to be beneficial in treating stress related disorders, improving autonomic functions, lower blood pressure, increase strength and flexibility of muscles, improve the sense of well-being, slow ageing process, control breathing, reducing signs of oxidative stress and improving spiritual growth. AIMS: The aim of present study was to investigate whether regular practice of Yoga for three months can reduce the cardiovascular hyper-reactivity induced by cold pressor test. MATERIALS AND METHODS: The study group comprised 62 healthy male subjects of 17-27 years age group. Initially there were 30 hyper reactors to cold pressor test. The hyper-reactivity of 23 volunteers converted to hyporeactivity after the yoga therapy of three months (76.66%). Other parameters like basal blood pressure, rise in blood pressure, pulse rate and rate of respiration were also statistically significantly reduced (by using student 't' test). STATISTICAL ANALYSIS: 2 tail student't' test was done by using the standard formulas. RESULTS: Regular practice of yoga significantly reduces the cardiovascular hyper-reactivity in basal blood pressure, rise in blood pressure after one minute of cold stress, heart rate, and rate of respiration, after three month of yoga practice. CONCLUSION: Regular practice of yoga for three months reduced the cardiovascular hyper-reactivity to cold pressor test in subjects, who were hyper reactive to cold stress, possibly by inducing parasympathetic predominance and cortico-hypothalamomedullary inhibition.
