ABSTRACT
Purpose@#The etiology and pathogenesis of distal colitis (DC) are poorly understood. Activation of intestinal inflammatory response may lead to intestinal tissue necrosis. Antioxidant and anti-inflammatory agents are among the treatment options. Our study aimed to compare the protective effects of mesalazine and Ganoderma lucidum in acetic acid (AA)-induced colitis in rats. @*Methods@#Twenty-four rats were randomly grouped as colitis, mesalazine, G. lucidum, and combined (G. lucidum + mesalazine) groups. DC was induced by intrarectal administration of AA. Statistical comparisons were done by using parameters including colonic tissue IL-1, IL-6, TNF-α, and CRP levels. Histopathologic changes of the samples of colonic tissue were scored as mucosal damage score and inflammatory score. A P-value of <0.05 was considered significant. @*Results@#Intrarectal administration of AA leads to increased interleukin and CRP levels. High mucosal damage and inflammatory scores were noted in colitis group animals. Single mesalazine or G. lucidum treatment produced considerably decreased tissue interleukin and CRP levels. The lowest tissue interleukin and CRP levels were noted in the combined treatment group of animals. Mucosal damage and inflammatory scores were found to be significantly low in this group of animals. @*Conclusion@#The intrarectal administration of AA results in an activation of intestinal inflammation and severe mucosal damage in colonic tissue. Single use of mesalazine and G. lucidum treatment decreases the severity of intestinal inflammatory response and mucosal damage. The healing effects of the combined treatment of mesalazine and G. lucidum seem to be more effective than that of separate use in the treatment of DC.
ABSTRACT
Purpose@#Due to the increasing prevalence of obesity worldwide, non-alcoholic fatty liver disease (NAFLD) has reached epidemic dimensions over time. NAFLD is the most common cause of childhood chronic liver disease. There is a relationship between NAFLD and oxidative stress. This study aims to investigate the changes in thiol/disulfide homeostasis parameters to determine the oxidant/antioxidant balance in obese rats with diet-induced NAFLD and healthy rats. @*Methods@#Twelve Wistar albino rats were used in this study. Experimentally produced NAFLD obese rats (n=6) and healthy rats were compared. Experimental NAFLD model was created with a special fatty liver diet (Altromin ® C1063, Fatty Liver Diet, Exclusivet, Lage, Germany). The biochemical and histopathological features of the groups, as well as serum thiol/disulfide homeostasis parameters, were analyzed and compared. @*Results@#In the experimentally induced NAFLD rat model, they gained more weight than the control group. Steatosis (at least grade 2) occurred in all rats fed with special fatty liver diet for 12 weeks. Histopathologically, no high-grade inflammation was observed in rats with experimental NAFLD after feeding a diet for 12 weeks. Results revealed that aspartate transaminase and alanine transaminase levels were high, albumin levels were low, oxidant stress parameters increased, and antioxidant thiol groups decreased. @*Conclusion@#Experimental NAFLD is characterized by increased oxidant stress accompanying fatty tissue in the liver. Analysis of thiol/disulfide homeostasis parameters in NAFLD can be used in further studies to develop effective treatment options.
