Biological Effects of Aqueous Extract of Laurus noboilis L. Leaves on Some Histological and Immunological Parameters in Male Rat Liver Affected by Aluminum Chloride.

The present current study aimed to assess the protective effect of the aqueous extract of Laurus noboilis L. leaves against the toxic effects of aluminum chloride on liver tissue. A number of 36 male albino rats (Wistar) were randomly assigned to six groups (n=6) and treated for 30 days: Group 1 was regarded as the control group, Group 2 received Aluminum Chloride 90 mg/kg body weight orally by gavage, Group3: normal rats received aqueous extracts of Lurus Nobilis L. leaf 150 mg/kg body weight, Group 4: normal rats received aqueous extracts of Lurus Nobilis L. leaf 200 mg/kg body weight, Group 5: normal rats received aqueous extracts of Lurus Nobilis L. leaf 150 mg/kg body weight after a period of 4 h following treatment by Aluminum Chloride 90 mg/kg body weight, Group 6: normal rats received aqueous extracts of Laurus nobilis L. 200 mg /kg after a period of 4 h following treatment by Aluminum chloride with 90 mg/kg body weight. All the experimental animals were sacrificed, and sections of their liver were stained with Hematoxylin-Eosin for histological evaluations. Moreover, the liver enzymes and immune cytokines, such as Alkaline phosphatase (ALP), Alanine aminotransferase (ALT), and Aspartate aminotransferase (AST), tumor necrosis factor-alpha (TNF-alpha), and interleukin-10 (IL-10) were measured. As evidenced by the results of the current study, treatment with aqueous extract of Lurus Nobilis L. leaves at a dose of 150 and 200 mg/kg body weight orally contributed to the mitigation of the toxic effects of Aluminum Chloride in albino rats by reducing the damage and inflammation in the hepatocytes. The study suggested that the aqueous extract of Lurus Nobilis L. enhances the protective effect against liver toxicity.

Infiltration of wounds and extraperitoneal space with local anesthetic in patients undergoing laparoscopic totally extraperitoneal repair of unilateral inguinal hernias: a randomized double-blind placebo-controlled trial.

BACKGROUND: The potential analgesic benefit of infiltration of the wounds and extraperitoneal space with local anesthetic in patients undergoing laparoscopic totally extraperitoneal (TEP) repair of inguinal hernias remains unclear. METHODS: Consenting adults scheduled to undergo laparoscopic TEP repair of unilateral inguinal hernias were recruited to this randomized double-blind placebo-controlled clinical trial of 0.25% bupivacaine (Group I) versus saline (Group II) infiltration of abdominal wounds and the extraperitoneal space. Pain scores were assessed at 4 and 24 hours postoperatively using the short-form McGill pain questionnaire (SF-MPQ), the Present Pain Index (PPI) score and the visual analogue scale (VAS). The intravenous and oral analgesic requirements were recorded. Each patient completed questionnaire to assess their satisfaction with the postoperative analgesia. RESULTS: 40 patients were randomized (Group I, n = 20; Group II, n = 20). The two groups were comparable for age, gender, body mass index, and operating time. Minor complications occurred in one patient in each group. There were no significant differences in the postoperative SF-MPQ scores, PPI and VAS at 4 hours (p = 0.413, p = 0.631, p = 0.615 respectively) and 24 hours (p = 0.116, p = 0.310, p = 0.100 respectively) post-operatively. The parenteral and oral analgesics consumed post-surgery were comparable (p = 0.605, p = 0.235). No difference was ob-served in the patient satisfaction scores. CONCLUSIONS: Infiltration of abdominal wounds and extraperitoneal space with bupivacaine in patients undergoing laparoscopic TEP repair of unilateral inguinal hernias does not appear to offer analgesic benefits.Key words: Laparoscopic; extraperitoneal; inguinal hernia; repair; pain; bupivacaine; analgesia; satisfaction; day case; randomized.
