This study aims to determine the effects of rosmarinic acid which involved the mechanisms to decrease the postoperative peritoneal adhesion formation in rats. Various incisions and removing a 1 × 1 cm piece of peritoneum was used to induce the peritoneal adhesions. Experimental groups were as follows: 1—Sham group. 2—Control group: Peritoneal adhesions were induced and no treatments were performed. 3—Treatment groups: Following inducing peritoneal adhesions, animals received rosmarinic acid with 50 and 70 mg/kg dosage, respectively. Macroscopic examination of adhesions indicated that adhesion bands were reduced in both treatment groups compared to the control group. Moreover, the adhesion score was decreased in both treatment groups on day 14. Inflammation and fibroblast proliferation were both reduced in the treatment groups on day 14. TGF-β1, TNF-α, and VEGF were all evaluated by western blot and immunohistochemistry on days 3 and 14. Treatment groups reduced inflammatory cytokines on days 3 and 14. The treatment group with a 70 mg/kg dosage decreased TGF-β1 and TNF-α levels more than the other treatment group. The administration of rosmarinic acid significantly reduced MDA and increased CAT levels. In conclusion, the rosmarinic acid was effective to reduce the adhesion bands, inflammatory cytokines, angiogenesis, and oxidative stress.
Background: Pain control methods after cesarean section may interfere with infant breast-feeding. The aim of this study was to evaluate the effect of pethidine on breast feeding of infants born via cesarean section with spinal anesthesia. Methods: In this randomized double-blind clinical trial, we evaluated 116 infants born via cesarean section in Gerash Amiralmomenin hospital (Southern Iran) in 2017. The subjects were selected through purposive sampling and randomly by permuted block randomization and assigned to intervention and control groups. The test group received 100 mg of pethidine as intravenous infusion and the control group received only routine cares. Infants’ breast feeding behavior in both groups was recorded within 48 hours of hospitalization, using the standard tool for rapid assessment of infant feeding behavior, which consists of 4 main components of breastfeeding, including readiness to feed, rooting, latching, and sucking with a score range of 0 to 3 for each component evaluated at 1, 6, 12, 24, 36, and 48 hours postnatally. Data were analyzed using independent t tests and chi-square test. Results: The highest score of breast-feeding behavior pertained to sucking reflexes in the control group and the lowest score to breast feeding readiness in the pethidine group. Readiness for feeding in the control group (2.09±0.53) was significantly higher than the pethidine group (1.81±0.61) (95% CI: 0.0552, 0.5092 and P=0.015). Sucking reflex (95% CI: -0.1461, 0.2208 and P=0.687), latching (95% CI: -0.3012, 0.0345 and P=0.118) and rooting reflexes (95% CI: -0.1685, 0.2342 and P=0.747) were almost equal in the control group (2.54±0.49, 2.52±0.38, 2.5±0.48, respectively) and pethidine groups (2.51±0.43, 2.65±0.45, 2.46±0.53, respectively). The total score of feeding behavior in the control group (9.66±1.04) was higher than that of the pethidine group (9.44 ±.69) (95% CI: -0.2032, 0.6412 and P=0.306). There was no significant difference between the infants’ feeding frequency (95% CI: -0.269, 1.930 and P=0.137) and duration of feeding (95% CI: -3.2067, 0.4597 and P=0.14). Conclusion: Evaluation of infants in the first 48 hours after birth showed that those babies whose mothers received pethidine were less willing to start breast-feeding. However, other components of breast-feeding behaviors were similar.
