Synthesis Of Silver Nanoparticles Using Anisomeles Malabarica Leaf Extraction With Cotton Fabric

The aim of this study was to investigate the aqueous leaf extracts of Anisomeles Malabarica and synthesized silver nanoparticles using aqueous leaf extract extract of plant parts to produce extremely secure silver nanoparticles in water. The results recorded from UV–vis spectrum, scanning electron microscopy, X-ray diffraction, and Fourier transform infrared support the biosynthesis and characterization of silver nanoparticles. The maximum efficacy was observed in crude methanol, aqueous, and synthesized silver nanoparticles. The results shows that the leaf of methanol extracts of Anisomeles Malabarica and bio synthesis of silver nanoparticles have the potential to be used as an ideal eco-friendly approach for the control of anti bacterial activity.

Therapeutic potential of yoga practices in modifying cardiovascular risk profile in middle aged men and women.

AIMS OF STUDY: To study effect of yoga on the physiological, psychological well being, psychomotor parameter and modifying cardiovascular risk factors in mild to moderate hypertensive patients. METHODS: Twenty patients (16 males, 4 females) in the age group of 35 to 55 years with mild to moderate essential hypertension underwent yogic practices daily for one hour for three months. Biochemical, physiological and psychological parameters were studied prior and following period of three months of yoga practices, biochemical parameters included, blood glucose, lipid profile, catecholmines, MDA, Vit. C cholinesterase and urinary VMA. Psychological evaluation was done by using personal orientation inventory and subjective well being. RESULTS: Results showed decrease in blood pressure and drug score modifying risk factors, i.e. blood glucose, cholesterol and triglycerides decreased overall improvement in subjective well being and quality of life. There was decrease in VMA catecholamine, and decrease MDA level suggestive decrease sympathetic activity and oxidant stress. CONCLUSION: Yoga can play an important role in risk modification for cardiovascular diseases in mild to moderate hypertension.

Effect of yogic practices on subjective well being.

Forty eight healthy volunteers who participated in the practice of yoga over a period of 4 months were assessed on Subjective Well Being Inventory (SUBI) before and after the course in order to evaluate the effect of practice of yoga on subjective feelings of well-being and quality of life. A significant improvement in 9 of the 11 factors of SUBI was observed at the end of 4 months, in these participants. The paper thus, reiterates the beneficial effects of regular practice of yoga on subjective well being.

Stress due to exams in medical students--role of yoga.

A student under optimal stress does bring out his or her best, However extremes of stress can result in stress induced disorders and deteriorating performance. Can yoga be of benefit in stress induced effects in medical students? The present study was conducted in first MBBS students (n = 50) to determine the benefit if any of yogic practices on anxiety status during routine activities and prior to examination. Feedback scores were assessed to determine how the students had benefited from the practices. Anxiety status as assessed by Spillberger's anxiety scale showed a statistically significant reduction following practice. In addition the anxiety score which rose prior to exams showed a statistically significant reduction on the day of exam after practice. These results point to the beneficial role of yoga in not only causing reduction in basal anxiety level but also attenuating the increase in anxiety score in stressful state such as exams. The results of the exam indicated a statistically significant reduction in number of failures in yoga group as compared to the control group. The improvement in various parameters such as better sense of well being, feeling of relaxation, improved concentration, self confidence, improved efficiency, good interpersonal relationship, increased attentiveness, lowered irritability levels, and an optimistic outlook in life were some of the beneficial effects enjoyed by the yoga group indicated by feedback score.

A simple technique for hemoglobin estimation to screen for anaemia.

Drabkins method has been modified enabling detection of anaemia in a large population. 132 samples of EDTA blood were subjected to hemoglobin estimation by (1) Direct Drabkin (DD) (2), Filter Drabkin (FD) and (3) Special Filter Drabkin (SFD). Hemoglobin estimations by DD and FD compared well on statistical analysis. SFD with a punch diameter of 10.6 to 10.7 mm compared well with DD and is ideal for screening anaemia in field studies.

Evaluation of anxiety status in medical students prior to examination stress.

Pulse rate (PR), blood pressure (BP), auditory reaction time (ART), galvanic skin resistance (GSR), and eosinophil count (EC) were determined in 30 male and 25 female medical students appearing for the I MBBS viva-voce examination. Two readings were taken viz 2 months (control) and 20 min prior to the examination. A statistically significant increase was seen in the PR and BP while a significant decrease was observed in ART, GSR and EC before the examination as compared to the control readings. There was a significant correlation between the PR and ART.

Comparative study of hemoglobin estimated by Drabkin's and Sahli's methods.

Hemoglobin was estimated by Sahli's and Drabkin's method in samples collected by finger prick and venepuncture. Statistical analysis revealed a significant difference in the hemoglobin values obtained by the two methods (P less than .01 & P less than .05 respectively). Sahli's method carried out by two different groups of workers in samples of blood collected by venepuncture showed statistically significant difference (P less than .001). This could be due to the inbuilt errors of Sahli's method including a subjective bias due to visual comparison. When same samples were subjected to Drabkin's method by the same group of workers no significant difference in the results were obtained (P less than .05). This is due to reliability of the Drabkins method. The aim of this comparative study of hemoglobin estimation by Sahli's and Drabkin's methods is to emphasize the sensitivity and reliability of Drabkin's over Sahli's and utility of Drabkin's method in undergraduate teaching schedule.

A preliminary study of reaction time in schizophrenics.

The aim of this study was to make a preliminary study of auditory reaction time (ART) and its significance in cases of schizophrenia. It was found that ART is significantly affected and prolonged in schizophrenia as compared to normal healthy controls (P less than 0.001) when the stimulus is presented to both ears or either car separately. Distractability was higher in schizophrenics as compared to adult controls (P less than 0.001). There was no significant difference in ART within the patient group when the stimulus was presented to the right ear or left ear (P greater than 0.05). There was no significant difference between ART of male and female schizophrenics (P greater than 0.05).

Study of reaction time in hemiplegics.

Visual reaction time and auditory reaction time (VRT and ART) were measured in 25 right hemiplegics and 25 left hemiplegics in the age group of 40-60 years. There was a significant prolongation of VRT and ART in both the right and left hemiplegics as compared to normals of the same age group. ART following mono-aural stimulation i.e. sound input into the right and left ear separately, was also studied in the subjects. Mono-aural stimulation revealed a prolongation of the ART on contralateral stimulation (i.e. auditory stimulation on the side, opposite to the brain damage) as compared to ipsilateral stimulation (auditory stimulation on the side of brain damage) in the right and left hemiplegics.

Effect of yogasanas on the visual and auditory reaction time.

Visual and auditory reaction time (VRT, ART) was studied in 83 healthy male subjects of 30-40 years of age who had never practiced yogasanas before. These subjects were divided into two groups viz. Group A whose VRT and ART was determined after 1 hr. yogasanas and Group B whose ART and VRT was determined after 6 weeks yogasanas training programme. VRT and ART showed a significant reduction in Group A (P less than .05) and Group B (P less than .001).

Apparatus for the measurement of reaction time.

An apparatus for the measurement of reaction time to both visual and auditory stimuli with a provision to vary intensity of stimuli and with facility for lateralisation of sound to the right or left ear has been described.

Effects of venous occlusion and local exercise on fibrinolytic activity and clotting time of blood.

Fibrinolytic activity (local) and the clotting time of blood after venous occlusion with and without accompaniment of active or passive exercise was studied in 21 medical students. All cases showed local significant increase in fibrinolytic activity, whilst the clotting time showed a significant fall indicating increased coagulability of blood, only when exercise accompanied venous occlusion.
