Introduction: "AUM" or "Om" is the name or symbol of God which is the combination of three letters, namely, A, U, and M. It is found that previous studies have evaluated only the long term effects of mantra chanting on experienced meditators. There is lacunae in evaluating the immediate effect of short duration of "aum" chanting in untrained subjects which will evaluate the strong potency of "aum" mantra chanting on mind relaxing physiological mechanisms to prevent and counteract the effects of stress related disorders.
Objective: The objective of this study was to evaluate the electroencephalographic pattern, galvanic skin resistance levels and heart rate during 5 minutes of "aum" mantra chanting in untrained subjects.
Methodology: The recordings of electroencephalogram, electrocardiogram and values of galvanic skin resistance levels were taken during the control period of rest before "aum" chanting for 5 minutes immediately followed by the test period which was during 5 minutes of "aum" chanting and the recordings continued for 5 minutes after the chanting procedure.
Results: Beta wave electroencephalographic pattern of 18-30 Hz. were recorded before chanting. During 5 minutes of "aum" chanting the subjects showed slow wave electroencephalographic patterns of theta and delta waves suggestive of mental relaxation and simultaneously there was a significant decrease in galvanic skin resistance values and an increase in heart rate (p< 0.05) which are suggestive of activation. Thus it is concluded that there is a combination of physiological relaxation and mental alertness even during short duration of "aum" mantra chanting.

Affiliation, pair bonding and love are important for survival, health and happiness. On the basis of various studies on neural mechanisms, endocrinal and genetic factors involved in various kinds of love, the purpose of this article is to hypothesize comprehensive, integrated neuroendocrinal mechanisms involved in pair bonding, romantic love, maternal and paternal love. The postulation depicted as flow charts at the end of this article seems to be triggered by various factors involving multiple neuroendocrinal mechanisms. It is concluded that the physiological mechanisms involved and the brain areas activated in each of these differ and the representation of postulated comprehensive mechanism in this article is an attempt to add a new dimension to understand the science of a very basic human quality of love.Keywords

Background: Though there are several studies available on effects of obesity on cardiac autonomic dysfunction and effects of COPD on cardiac autonomic dysfunction separately but search on combined effect of obesity and COPD on cardiac autonomic dysfunction fails to produce results. Therefore there was a need to evaluate the changes in autonomic dysfunction with increasing BMI in patients with COPD.
Objective: The aims of this study were 1) to compare autonomic dysfunction in patients with COPD with increasing BMI, 2) to correlate autonomic dysfunction in patients with COPD with increasing BMI.
Methodology: In the present study, 42 subjects were categorized into underweight, normal weight, overweight and obese category. Non invasive cardiac autonomic function tests were carried out in these subjects.
Results: The mean ± SD age of underweight, normal weight, overweight, and obese patients with COPD were 57.667 ± 5.1640, 61.007 ±8.8991, 55.800±6.6106 and 56.200±7.1204 respectively. It was found that there was no correlation between BMI and autonomic dysfunction responses in patients with COPD. All four cardiac autonomic function test came out to be non significant statistically [Karl Pearson correlation (r), ns-p >0.05]. Multiple comparisons between underweight, normal weight, overweight, and obese patients with COPD for cardiac autonomic responses, FEV1, PEF were statistically non significant.
Conclusion: In present study, although the results have shown that there was definite autonomic neuropathy in patients with COPD with increasing BMI, there was no significant difference in autonomic dysfunction with increasing BMI in patients with COPD.
