Objective: St. John's wort (SJW) oil (Hypericum perforatum) has been used for its immunomodulatory and anti-inflammatory effects. Several studies have shown the efficacy of SJW on wound healing. The aim of this study is to assess the effectiveness of SJW using a combination of biochemical, histopathological and laser Doppler evaluations. Materials and Methods: Sixteen young Wistar albino rats were used as case and control groups (having 8 in each group). After anesthesia protocol, 6 mm punch biopsy was taken from six separate sites on the rats' dorsal skin. Three wounds were stitched (closed wounds)

Introduction: Laparoscopic surgery is a preferred method based on its many benefits. However, increasing abdominal pressure by CO2 insufflation during the implementation of this technique poses challenges. Aim: To determine the degree of renal and liver injury that occurs in a pneumoperitoneum (PP) model of prolonged CO2 insufflation. Material and methods: Twenty-one female Sprague Dawley rats were separated randomly into three groups. Group 1 was the control group and given anesthesia for 3 h. In group 2, PP was administered under anesthesia for 1 h. In the last group, PP was administered under anesthesia to animals for 3 h. We measured renal and liver injury biomarkers and made a histopathological evaluation to estimate the degree of injury and assessed the correlation of biomarkers including kidney injury molecule-1 (KIM-1) with histopathological findings. Results: Histopathological analysis according to the kidney ischemia tubular damage score showed a statistically significant difference between the 3 groups (p < 0.001). There was an increase in KIM-1 levels in the groups, although it was not statistically significant (p = 0.062, p = 0.156, p = 0.350 respectively). According to the correlation test in this research, KIM-1 results had a statistically significant association with creatinine, urea, aspartate aminotransferase and alanine aminotransferase levels in all control and study groups. Conclusions: According to our results, the increase in KIM-1 was correlated with Cr levels and compatible with histopathological analysis. Moreover, intra-abdominal pressure statistically significantly increased the degree of kidney injury and there was not a significant increase in the levels of KIM-1. There was no difference in liver damage between groups.
