Background:Cigarette smoking induced increased sympathetic activity is one of the major independent risk factor for cardiac morbidity and mortality. Objective:To assess acute effects of smoking on neuro cardiovascular regulation by analysis of time domain measures of HRV in current regular healthy male cigarette smoker. Methods:This comparative analytical study was conducted in the Department of Physiology, Bangabandhu Sheikh Mujib Medical University (BSMMU), Shahbag, Dhaka from July 2011 to June 2012. 120 apparently healthy male current regular cigarette smoker aged 20-55 years were participated in the study group. Age and BMI matched 70 apparently healthy male non smoker subjects were studied as control. To observe the acute effects data were recorded 5 and 30 min after finishing a cigarette. Time domain measures of HRV were recorded by a RMS digital polyrite D. Statistical analysis was done by independent sample t test and paired sample t test. Results: Resting pulse rate, SBP, DBP, mean heart rate were significantly higher (p<0.001) and mean R-R interval, SDNN, RMSSD and total power were significantly lower (p<0.001) in all smokers in comparison to those of healthy control.In addition, all time domain parameters were significantly decreased from their corresponding baseline value just 5 minutes after smoking and returned close to their baseline value after 30 minutes of smoking but it remained significantly lower than control value. Conclusion: The result of this study concludes that cigarette smoking had acute effect on cardiac autonomic function causing depressed vagal activity and overbalance of sympathetic function.

Background: Cigarette smoking is associated with various forms of acute cardiac events such as myocardial infarction and ventricular fibrillation etc.Objective: To observe immediate impact of cigarette smoking on power spectral measures of heart rate variability (HRV) in current apparently healthy male regular cigarette smokers.Methods: This study was carried out on 120 apparently healthy male current regular cigarette smoker aged 20-55 years. To watch the intense impacts, data were recorded 5 and 30 min after completing a full stick of cigarette. Power spectral measures of HRV were recorded by a RMS digital polyrite D. Statistical analysis was done by paired sample t test.Results: LF power, LF nu & LF/HF ratio were significantly increased and HF power & HF nu were significantly decreased from their corresponding baseline value just 5 minutes after smoking and returned close to their baseline value after 30 minutes of smoking.Conclusion: The result of the study concludes that acceleration of sympathetic activity with simultaneous withdrawn of cardiovascular vagal adjustment happens quickly in the wake of smoking a cigarette.J Bangladesh Soc Physiol. 2018, June; 13(1): 8-12

Eating while walking is a commonly growing practice in the United States, in part due to an increase in the number of convenient dietary products (i.e., snack bars, shakes, drinks, etc.). Although eating while walking has been shown to increase total food consumption and weight gain, the acute effects of eating while walking on blood glucose (BG) concentrations are still unknown. The purpose of this study was to investigate the acute effects of eating while walking on BG. Twenty-two apparently healthy, male, physically active (PA, n = 10) and sedentary (Sed, n = 12) individuals volunteered for this study. Participants randomly performed the control [sit+snack (SS)] and experimental [walk+snack (WS)] protocol, with one week between protocols. Both protocols showed a significant increase in post-BG concentrations [SS (p < 0.001); WS (p < 0.01)], but post-BG concentrations for WS were significantly lower (p < 0.001) than SS. During SS, significantly higher post-BG concentrations were exhibited for the PA (p < 0.05) and Sed (p < 0.01) groups, whereas the WS protocol post-BG concentrations were significantly increased for the Sed group (p < 0.01). Lastly, individuals who exercised more and had a lower body mass index (BMI) were significantly correlated to lower BG concentrations in response to the 47 g carbohydrate (CHO) snack. However, these data are preliminary and may need further investigation.

Background: Cigarette smoking is one of the strong contributors to the risk of development of cardiovascular diseases including coronary artery disease, stroke, sudden death, peripheral artery disease & aortic aneurysm. Objective: To assess HRV by time domain methods in healthy cigarette smokers. Methods: This cross sectional study was conducted in the Department of Physiology, Bangabandhu Sheikh Mujib Medical University (BSMMU), Shahbag, Dhaka from July 2011 to June 2012. 120 apparently healthy male current regular cigarette smokers (Group B) aged 20-55 years were enrolled in the study group.70 apparently healthy male non smoker subjects (Group A) were taken as control. Time domain measures of HRV were recorded by a RMS digital Polyrite. Statistical analysis was done by independent sample t test. Results: Resting Pulse, SBP, DBP, Mean heart rate was significantly higher (p<0.001) and Mean R-R interval, SDNN, RMSSD were significantly lower (p<0.001) in all smokers compared to control. Conclusion: Generalized reduced HRV & attenuated cardiac vagal modulation occur in apparently healthy cigarette smokers.

Background: Immersion has been used for many years for therapeutic purposes, but more recently the cardiovascular and authonomic effects appear as an important change in the organism during immersion in the aquatic environment.Objectives: The aim of this study was to investigate the acute effect of water immersion (22.6 °C) on heart rate, heart rate variability, body temperature, oxygen saturation, diastolic blood pressure and systolic blood pressure in young apparently healthy men.Method: Nine apparently healthy males were randomly allocated to an experimental situation (SE) and one control (SC). The SE subjects had the variables measured after the 10 minutes immersion. The subject of the SC remained 10 minutes at rest in the terrestrial environment. After 48h, the procedures were performed the reverse manner to perform balanced input.Results: After 10 minutes of immersion in water was observed reduction in the values of heart rate, significant increases on the RR intervals. The values of RMSSD (ms) increased after immersion, as shown pNN50 (%) and HF index increased (p = 0.009). The ratio (LF / HF) decreased after immersion. Significant differences when comparing the SBP were observed.Conclusions: Thus, is concluded that the immersion in water (22.6º C) increases vagal activity and reduces modulation of the sympathetic branch of the autonomic nervous system.

The use of Cannabis sativa is on the increase worldwide especially among adolescents and youths. This study investigated the effect of cannabis smoking on renal functions in young and apparently healthy male students of Nnamdi Azikiwe University, Nnewi campus, Anambra state, Nigeria. A total of 60 male (40 cannabis smokers and 20 controls) subjects participated in this study. A well-structured questionnaire was used to obtain the demographic data and anthropometric of subjects. Thereafter, 5mls of fasting blood sample was collected from the subjects into plain container for the estimation of biochemical parameters (creatinine, urea, uric acid, electrolytes). Renal parameters were estimated using standard methods. Data obtained were statistically analyzed using paired student t-test and pearson r correlation. Result showed that the mean serum levels of urea, creatinine, K+, Na+, Cl-, ionized calcium, total calcium, total carbon dioxide, anion gap, and pH were not significantly different in both smokers and control subjects(p>0.05). However, there was significantly higher mean serum level of uric acid (2.42 ± 38.54 vs 1.92 ± 41.61; p<0.05) and total calcium (16.0 ± 0.30 vs 10.24 ± 0.18; p<0.05) in smokers compared with control subjects. Again, BMI was significantly higher in smokers compared with non-smokers (23.96 ± 3.15; p<0.05 Vs 21.95 ± 2.17; p<0.05). Therefore, cannabis use had no deleterious effect on the kidneys, but the significantly higher uric acid levels in the smokers may provide some anti-oxidant protection. However, further studies are necessary to further unravel the full potentials of cannabis use.
