Abstract
Background: Soy products contain several compounds with anti-inflammatory properties like genistein and daidzein which reported to act through different pathways. Present study conducted considering the inconsistent results and lack of any comprehensive review regarding randomized controlled trials which assess the effect of soy products on inflammatory markers. Methods: Following electronic databases were searched up to March 2020: PubMed, Scopus, ISI web of science, and Cochrane Library All randomized trials which assessed the effect of soy product supplementation on c-reactive protein (CRP), tumor necrosis factor-alpha (TNF-alpha) and interleukin-6 (IL-6) were included for last analysis. Treatment effects were expressed as mean difference (MD) and the standard deviation (SD) of outcomes. To estimate the overall effect the random-effects model was employed. Results: Finally, 51 randomized trial were included for present study. Last analysis showed that soy product supplementation lead to significant reduction in CRP (MD -0.27 mg/L; 95% CI: -0.51, -0.02, p = 0.028) but it did not affect IL-6 (MD 0.0 pg/ml; 95% CI: -0.06, 0.06, p = 0.970) and TNF-alpha (MD = -0.04 pg/ml; 95% CI: -0.11, 0.03, p = 0.252). Subgroup analysis showed that soy supplementation had a significant impact on decreasing IL-6 and TNF-alpha levels when studies had a long-term intervention (>= 12 weeks) and used low dose isoflavone (< 100 mg/day). Conclusion: In conclusion, present systematic review and meta-analysis found a significant reduction in CRP levels after soy supplementation whiles IL-6 and TNF-alpha did not affect.

Abstract
Objective(s): This study was designed to assess the effect of fraxin which has various biological properties against liver injury induced by cisplatin. Materials and Methods: In our study, 24 Wistar albino rats were randomly assigned to control, fraxin, cisplatin, and fraxin+cisplatin groups. Cisplatin 12 mg/kg IP and fraxin 40 mg/kg orally were applied. When the experiment ended, the rats were sacrificed and the liver tissues were taken rapidly. Liver tissue specimens were maintained under appropriate conditions. Later, biochemical, histopathological, and immunohistochemical evaluations were performed. Results: According to our biochemical findings, oxidant parameters increased while antioxidant parameters decreased in cisplatin group compared with control group. Antioxidant parameters increased but oxidant parameters decreased in fraxin + cisplatin group compared with the cisplatin group. Immunohistochemical evaluations showed that the expressions of TNF-alpha and Caspase-3 were negative in control and fraxin groups, whereas severe levels were found in the cisplatin group. However, it was determined that the expressions of TNF-alpha and Caspase-3 were in mild levels in fraxin + cisplatin treatment group. In addition, it was observed that the increase of pathological markers such as coagulation necrosis, hydropic degeneration, dilatation in sinusoid, and hyperemia in the cisplatin group were compatible with our biochemical and immunohistochemical findings. Conclusion: Biochemical, immunohistochemical, and histopathological results revealed that fraxin was effective in relieving cisplatin-induced liver damage.
