Aims: Wound healing is a complex physiological process involves a series of successive stages of hemostasis, inflammation, proliferation, and regeneration. This study aimed to investigate the effect of hydroalcoholic extract of Brassica oleracea L. (var. capitata) leaves in comparison with Phenytoin on epithelial layer healing and the holes in the skin of mice. Materials & Methods: This study was done on 40 male NIH Mice between 25-30gr. Animals were randomly divided into 4 groups (n=10). Negative control group received saline, positive control group administrated with 1% Phenytoin and treated groups received 10% and 20% hydroalcoholic extract twice a day until closing holes. Macroscopic and microscopic analysis was performed on days 1, 4, 7, 12 and 15. Statistical analysis was done by SPSS 16 software and Tukey test. Findings: A significant reduction was observed in average size of holes in 20% hydroalcoholic extract treated group compared to the negative control 10% extract at day 7 (p=0.001). There was a significant reduction in average size of holes in 20% extract group compared to 10% extract and negative control groups at day 12. (p=0.007). The skin holes in 20% extract group were closed earlier than the other groups. Epithelial thickness was increased in 20% extract group from 7th day the much faster than other groups. Conclusion: Brassica oleracea L. (var. capitata) has the same effect of phenytoin in healing of rapid closure of holes and proliferation of epithelial cells.
Experiencing complications within the first two weeks after stroke leads to a high risk of mortality and length of hospitalization. The present pilot study was intended to investigate the hypothesis that adult patients treated with safflower or not would present with fewer neurological complications following 15 days. In a randomized controlled trial, subjects diagnosed with ischemic cerebrovascular accident (CVA) based on focal neurological findings on brain imaging who met the inclusion criteria of our study were recruited from Ghaem Hospital, Mashhad, Iran, between 2016 and 2017. Thirty-six patients were included in the survey and randomly allocated into treatment (A) and control (B) groups. An oral syrup of safflower extract and nasal drop of safflower oil were additionally prescribed for group A. Group B only received a standard anti-ischemic regimen. The primary outcome measure was the National Institutes of Health Stroke Scale score (NIHSS) over 15 days. Safflower treatment led to a notably higher mean difference in the NIHSS score between the baseline score and 15-day post-treatment score in group A in comparison to group B (p < 0.001). However, adjustment for covariates (age, gender, and baseline measures) showed no significant reduction in neurological status between them (p = 0.340). There was a statistically significant difference in neurological symptom scores between the groups (p = 0.044). Based on this pilot study, adjuvant treatment with safflower in addition to the standard anti-ischemic regimen can be more effective than individual conventional drugs for treating ischemic CVA among adults.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
