{"title":"Gender Differences in Response to Cold Pressor Test in the Age Group of 18-30 Years","authors":"Hasana Fatima, R. Anitha, Mudassir Mirza","doi":"10.37506/ijop.v8i3.1327","DOIUrl":"https://doi.org/10.37506/ijop.v8i3.1327","url":null,"abstract":"Introduction: The Cold Pressor Test (CPT) was first introduced by Hines and Brown in 1932. It was \u0000designed to measure the reactivity of the blood vessels to a standard stimulus2 . Cold Pressor Test is an \u0000established challenge test of sympathetic vascular regulation. Sympathetic nervous system activity varies in \u0000males and females. \u0000Aim: To study the response of Cold Pressor Test on blood pressure in normal healthy young adult males \u0000and females. \u0000Materials and Method: After Institutional ethics committee approval, a total of 104 subjects in the age \u0000group of 18-30 years were recruited with informed consent for the study, after considering inclusion and \u0000exclusion criteria. Subjects were explained about the test procedure. Basal blood pressure (pre-test BP) \u0000was recorded after 20 min. of rest. Systolic and diastolic blood pressure was measured in mmHg (pre-test). \u0000Subject was asked to dip left hand till the wrist in cold water (40-80 C) for 1 min. (minute).Blood pressure \u0000was recorded from right arm during the test, 1 minute, 2 minutes, 3 minutes and 4 minutes after the test. \u0000Result: Basal BP was significantly higher in males than in females. Systolic BP(SBP) response, Diastolic \u0000BP response (DBP) to CPT were statistically higher in males compared to females. \u0000Conclusions: The gender variations are seen due to differences in the sympathetic nervous system activity \u0000and due to the effect of sex hormones. Males are more prone to develop hypertension and other cardiovascular \u0000disorders when compared to females due to higher sympathetic activity.","PeriodicalId":92916,"journal":{"name":"International journal of physiology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46172522","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Impairment of heart rate variability (HRV) has been observed in patients with CAD. Percutaneous transluminal coronary angioplasty (PTCA) is one of the common modalities of treatment of CAD. In this study we have studied the effect of successful elective PTCA on HRV parameters in patients with CAD. Material and Method: HRV parameters in both time and frequency domain were studied in 30 male patients before PTCA, one day and three day after PTCA. Results: - The time and frequency domain parameters between pre PTCA and 1 st day post PTCA were not found to be statistically significant. Changes in the time domain parameter rMSSD and SDNN was statistically significant between pre and 3 rd day post PTCA but no significant difference was observed in pNN50. A significant decrease in LF n.u and increase in HF n.u was observed between pre and 3 rd day post PTCA. Conclusion: Revascularization with PTCA results in improvement of the autonomic tone. Improved autonomic modulation is seen as early as 3 rd day post PTCA. It indicates that restoring the blood flow reverses to some extent the autonomic modulatory effect of coronary artery disease.","PeriodicalId":92916,"journal":{"name":"International journal of physiology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47334212","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Of late recent studies have determined that vitamin D deficiency can cause several diseases such as diabetes, cardiovascular complications etc. Oxidative stress is an imbalance between free radicals and antioxidants in the body. Vitamin D is an antioxidant and its deficiency can cause oxidative stress .Thus vitamin D deficiency by itself and by causing oxidative stress can increase risk of developing diabetes Hyperglycemia can affect cognition. Oxidative stress too can affect cognition. Studies done studying the role of vitamin D affecting cognition especially in diabetics are very few. Aim: To determine the role of vitamin D in affecting cognition in Diabetic patients. To determine the correlation between vitamin D, oxidative stress and cognition in diabetes . obtaining ethical approval from the institution a structured questionnaire was given to all. Fasting blood glucose was by Method. Immunoturbidometry. stress (malonylaldehyde) reactive substances Montreal cognitive All were carried out the Results were analysed using Microsoft excel. Results: A negative correlation was seen between vitamin D and MOCA scores. A positive correlation was seen between MDA and MOCA scores. Conclusion: Vitamin D deficiency causes oxidative stress and affects cognition in diabetics. Vitamin D supplementation can be considered to reduce oxidative stress and thus improve cognition in diabetes mellitus patients.","PeriodicalId":92916,"journal":{"name":"International journal of physiology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41860831","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Stress and anxiety affect their health and well-being \u0000and causes mental disturbance. Blood pressure, heart rate, and other biochemical parameters show an \u0000abnormal rise due to stress and anxiety. Music therapy using Indian classical instrumental music can help \u0000relieve this stress and anxiety and bring the biochemical parameters to normal levels. \u0000Aim: The purpose of the present study was to evaluate the immediate and short term effects of Indian \u0000classical instrumental music on stress and anxiety using both qualitative and quantitative measurements on \u0000male medical students. \u0000Materials and Method: Fifty-six (56) healthy male medical students aged between 17-25 years were \u0000selected from Rajkiya Medical College, Jalaun (Uttar Pradesh), for a month-long music therapy which \u0000included listening to Indian classical instrumental music every day for thirty minutes. ADSS questionnaire, \u0000salivary cortisol, blood pressure, heart rate, and lipid profile other required parameters were recorded twice, \u0000once at baseline and another after one month of music therapy. \u0000Results: Post music therapy values revealed a significant decrease in ADSS score anxiety (4.36 ±1.39 v/s \u00003.36 ± 1.20 p<0.0001), depression (3.14 ± 1.70 v/s 2.23 ± 1.50, p<0.0001) Stress (4.54±1.91 v/s 3.39±1.77, \u0000p<0.0001) Salivary cortisol (4.04±1.39 v/s 3.33±1.35, p<0.0001).

Increased left ventricular mass might antedate the development of hypertension in the individuals destined to develop systemic hypertension in life.

Materials and Method: 75 healthy normotensive individuals with family history of hypertension and 75 healthy normotensive individuals without family history of hypertension were included in the study .LV mass was calculated by using 2D M-mode echocardiography by the formula given by American society of Echocardiography, LV mass= 0.8 × [ 1.04 × (LVIDd + IVSd + PWd)3 – (LVIDd)3] + 0.6 grams.[LVIDd – Left ventricular internal diameter during diastole; IVSd- Interventricular septal thickness during diastole; PWd – Posterior wall thickness during diastole].
