Abstract:Introduction: Yoga is a system of poses which inducts an effective and vigorous blood circulation and completely eliminates all impurities from the system. In this study, the effect of yogasanas on renal circulation was studied. Twist, back bends, forward folds and inner thigh stretches will increase the abdominal pressure and also stimulate the second chakra to increase the blood flow to the kidney.  The study was carried out to evaluate the effects of renal specific asanas in increasing the blood flow to the kidney.Materials and methods:The parameters Peak Systolic Velocity (PSV) and Resistive Index (RI) of renal blood vessels were assessed on forty female subjects in the age group between 17 -19 yrs using a colour Doppler before and after three months of yoga training. This study was conducted in the department of physiology in VMKV medical college, Salem between 4.30-5.30 pm everyday for 5 days in a weekConclusion:Yogasanas are said to increase the blood flow to almost all the parts of the body. Increase in blood flow to the kidney especially helps in removing the waste products thereby preventing water and salt accumulation. Our study  confirms that regular practice of yoga helps to maintain a healthy kidney and also, as an adjuvant therapy helps to improve the renal functions in patients who already suffer from renal disorders and reduce the dosage of the drugs.

Abstract:Background: The waste produced in the course of healthcare activities carries a higher potential for infection and injury than any other type of waste. Inadequate and inappropriate knowledge of handling of healthcare waste may have serious health consequences and a significant impact on the environment as well.Objective: The objective was to assess knowledge, attitude, and practices of doctors, interns, nurses, laboratory technicians, attenders and housekeeping staff regarding biomedical waste management. Materials and Methods: This was a cross-sectional study done in a medical college rural hospital. A total of 383 health personnel were included in the study with their prior consent. Study subjects include doctors (56), interns (65), nurses(83), laboratory technicians(44), attenders (78) and housekeeping staff (57).Results: Doctors, nurses have better knowledge than other staff regarding health care waste management. Knowledge regarding the colour coding and waste segregation at source was found to be better among nurses and laboratory staff. Regarding practices related to health care waste management nurses were better. However, injury reporting was nil across all the groups of health professionals.Conclusion: The importance of training regarding health care waste management needs emphasis; lack of proper and complete knowledge about biomedical waste management impacts practices of appropriate waste disposal.

An appraisal of aerobic capacity, flexibility, agility & reaction time in Basketball players & age matched controls.

Abstract :Introduction & background: Successful game of basketball needs ability of the players to generate good speed, agility and tremendous power during the play of game. Skills like dribbling, shooting and passing are of utmost importance for a player at any level of play. Not merely skills but also physical and physiological characteristic of a player will contribute to the success of the player as well as of the team. Optimal performance thus requires a combination of technical and tactical abilities as well as a high degree of physical fitness. Efforts, to improve the standard of our sportsmen, have achieved an insignificant success in this respect.Aims & objectives: The present study was undertaken to assess, analyze and compare aerobic capacity, flexibility, agility & reaction time in Basketball players & age matched controls. Also compare these results with national and international standards available.Material & method: Parameters like aerobic capacity using bicycle ergometer and modified Astrand’s nomogram, flexibility using goniometry & sit-reach test, agility using quadrant jump, burpees’ squat thrust & reaction time were assessed. As we lag far behind in scientific assessment of Indian basketball players this study thus aims at their fitness and game specific skills.There is a highly significant increase in VO2 max of the basketball than the control group. The trunk flexibility was significant while the shoulder and knee flexibility was highly significant in basketball players. The agility of the basketball players was not significantly different from controls except burpee’s squat thrust. The reaction time for audio-visual stimulus was significantly more in basketball players.


ABSTRACT Occurrence of variation of the Inca bones was observed in majority of human populations around the world. India has more Inca bones than do neighboring countries. Various geographical and ethnological patterns of frequency variation of the Inca bones were already found. Present study was done on 148 human skulls for the presence or absence of the Inca bones. We classified these bones as class I to class V. They were analyzed for gross incidence and number of fragments of bone. Gross incidence of the Inca bones was found to be 4.054%. The present study besides reporting the variation in the Inca bones also highlights possible genetic and evolutionary mechanism behind its presentation. These are important findings and the knowledge of the Inca bones is of importance to the neuroanatomists, neurosurgeons, radiologists, anthropologist and morphologists


ABSTRACT: Background: In recent times ,medical fraternity is much attracted towards yoga. It is claimed that yoga practices improve general health and fitness. Aim:  To find  effect of short term Yoga practice on cardio-respiratory fitness. Objective: To measure cardio-respiratory fitness parameters  before and after Yoga practice. Material:  The present study was conducted on 60subjects, who came voluntarily as subjects for the project. Setting and Design:  It  was a cohort study. I M.B.B.S.students ,60 in number(40 boys and 20 girls).Their age ranged between 18  to 20 years. Method: Pulse rate and respiratory rate measured in supine position.B.P. measured using mercury sphygmomanometer. 40 mm Hg endurance test was conducted by using mercury sphygmomanometer. Results: Resting pulse rate, Respiratory rate and blood pressure was found to be decreased and 40mm endurance time was found to be increased in both male and female subjects. Conclusion: From this study we conclude that yoga practice can be advocated to improve cardio-respiratory efficiency for patients as well as healthy individuals. 

Trifurcation of C5 root & its Clinical Importance

Abstract: Brachial plexus is a complex network of nerves, formed by ventral rami of lower four cervical and first thoracic nerves which supply the upper limb. Though its variations are common, terminal trifurcation of C5 is rare. During routine dissection in anatomy department, in an old male cadaver, multiple variations of brachial plexus were observed on the left side.  It was unique with the absence of superior trunk and lateral cord. The C5 root trifurcated terminally into suprascapular nerve, a root for musculocutaneous nerve (MCN) and posterior division for posterior cord. Musculocutaneous nerve was formed by two separate roots from C5 and C6. Axillary artery was intimately passing between two roots of MCN. Phrenic nerve carried fibres of the nerve to subclavius from C5. Knowledge of these variations is important not only for anatomists but also to neurosurgeons, physicians and anaesthetists for diagnosis, planning the surgeries and avoiding the complications. Key words – Brachial plexus, superior (upper) trunk, suprascapular nerve, musculocutaneous nerve, nerve impingement
