Effects of supplementation of amino acids, lysine and methionine on growth performance and feed utilization of sobaity sea bream juveniles, Sparidentex hasta

This study was conducted to determine the effects of dietary supplementation of lysine and methionine on growth and nutrient utilization of Sobaity sea bream, Sparidentex hasta.A total of 180 juvenile fish with an initial weight of 31.38 ±1.4 g were distributed randomly among eighteen tanks. Fish were fed to satiation three times per day (08:00, 13:00 and 18:00 hours) for 8 weeks with formulated diets containing six different levels of dietary methionine and/or lysine; Diet 1: a control diet without dietary amino acid supplementation; Diet 2: 100% methionine supplementation; Diet 3: 75% methionine and 25% lysine supplementation; Diet 4: 50% methionine and 50% lysine supplementation; Diet 5: 25% methionine and 75% lysine supplementation and Diet 6: 100% lysine supplementation. The results of this study showed that dietary lysine and methionine supplementation significantly affected (P<0.05) growth parameters and feed utilization. The fish fed with high level of methionine supplementation had significantly improved growth performance than the group fed the control diet and treatment 6. Highest feed conversion ratio, protein efficiency ratio and protein retention were observed in diet 3. Though lysine and methionine supplementation showed positive effects on growth and feeding performance, our results suggested that Sobaity juveniles probably required more methionine than lysine

Propranolol decreases the post-operative pain and analgesic administration following abdominal hysterectomy

Post-operative pain results in many complications. Studies suggest beta blockers to be effective in decreasing postoperative pain and analgesic requirements. This study evaluated the influence of perioperative administration of 40mg orally propranolol on patients' post-operative pain score and analgesic consumption following abdominal hysterectomy. In this double-blind randomized clinical trial, 73 women who had referred for elective abdominal hysterectomy surgery during years 2010-2011 were reviewed. Patients were randomly divided into case (receiving 40 mg orally propranolol tablet 30 min before surgery) and control (receiving orally placebo 30 min before surgery). General anesthesia was done the same for both groups. Postoperative time of first need to morphine, total morphine consumption dose and pain severity during the first 24 hours after surgery was measured among both groups. age and hysterectomy indication was not statistically different between two groups (p>0.05). Total morphine consumption in the propranolol group (2.85±2.5 mg) was lower than control group (10.35±2.2 mg) (p<0.001). The Initial morphine administration time (min) in the propranolol group was significantly longer than the control group (998.7 ± 49 vs. 261.7 ± 139.1) (p<0.001). The Pain Score (VAS scoring) (Mean±SD) in propranolol group was lower than the control group (1.03±0.58 vs. 2.76 ±0.8) (p< 0.001). administration of 40mg orally propranolol 30 minutes before abdominal hysterectomy is effective in decreasing patients' post-operative pain and morphine administration dosage. It also elongates the Initial morphine administration time in the first 24 hours following abdominal hysterectomy
