Résumé
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.

A significant decrease in the visual and auditory reaction times (VRT and ART) was found in 50 smokers as compared to healthy controls of the same age group (P less than 0.001). The acute effect of smoking one cigarette was also studied in the same group of smokers and a statistically significant reduction was found (P less than 0.001) as compared to their basal VRT and ART.

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).

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).

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.
