Lactate and lactate dehydrogenase [LDH] response to muscular exercise in male and female athletes

40 physical education students [20 males and 20 females] were participated in the present work in order to study lactate and LDH response to muscular exercise in male and female athletes. Blood was sampled in the morning following an overnight fast just before and after a physical exercise effort consisted of a progressive exercise test to exhaustion on a cycle ergometer. Blood samples were analyzed for lactate level and LDH activity. This study showed that exhaustive muscular exercise induced significant increase of level and LDH activity in both male and female with significant increase of blood lactate level in male than female. It was concluded, that the sex difference is one of the factors which affects the post exercise lactate level in athletes

Post-operative pain control using a local anesthetic

30 patients subjected to operations for open cholecystectomy [15 patients] and inguinal hernia repair [15 patients] received postoperative pain analgesia through perfusing their wounds with bupivacaine via a catheter inserted in the wound. 83% of them experienced no pain all through the 72 hours of the trial. and one patient only had severe pain on the same day of operation and needed one dose a narcotic. It can be concluded that, this method is safe, easy and less expensive and could be applied for most cases
