Article Citation - Scopus: 3Therapeutic Effects of Momordica Charantia L. Ethanolic Extract on Acetic Acid-Induced Ulcerative Colitis in Rats(Istanbul University Press, 2021) Ozbeyli, D.; Sen, A.; Aykac, A.; Terali, K.; Cilingir-Kaya, O.T.; Senkardes, I.; Sener, G.Objective: This study aims to investigate the effect of Momordica charantia L. (MoC) ethanolic extract on ulcerative colitis (UC) and was explored in vitro and in vivo. Materials and Methods: The rats were divided into control (C), saline-treated colitis (AA), MoC extract-treated colitis (AA+MoC), and sulfasalazine (SS)-treated colitis (AA+SS) groups. Colitis was induced by acetic acid. MoC extract, SS or saline were given to the related groups for 3 days. Interleukine-1β, malondialdehyde, glutathione levels, myeloperoxidase activity, bax/bcl-2 ratio, caspase-9 and caspase-3 levels were measured in colon and macroscopic and histopathologic examinations were done. Total phenolic/flavonoid content and biological activity of MoC were evaluated by in vitro analysis. Results: Compared to the control group, with acetic acid application interleukin-1β levels, myeloperoxidase activity, malondialdehyde levels, bax/bcl-2 ratio, caspase-9 and caspase-3 levels were significantly upregulated, while glutathione levels were significantly decreased in the AA group. In contrast, MoC and SS treatments reduced interleukin-1β, malondialdehyde levels, myeloperoxidase activity, bax/bcl-2 ratio, and caspase-9 and caspase-3 levels. Glutathione levels increased upon MoC or SS treatment. Increased macroscopic and microscopic scoring with AA improved with MoC or SS treatment, but the MoC or SS treated groups had higher score values than the control. Also, in vitro results showed that MoC exhibited 2,2-diphenyl-1- picrylhydrazyl and 2,2'-azino-bis-3-ethylbenzothiazoline-6-sulfonic acid radical scavenging activity as well as significant antilipoxygenase activity. In addition, MoC extract showed a potent anti-inflammatory activity compared to standard indomethacin. Conclusion: Our biochemical, in vitro and histopathologic analysis indicate that MoC is likely to prove beneficial in UC therapy. © 2021 European Journal of Biology.

Nephrolithiasis is proven to be the result of various biochemical and inflammatory processes that result in crystal formation and subsequent aggregation. Cotinus coggygria L. (CCog) is a plant extract which has been used as a Turkish remedy for kidney stones. With this study, we planned to evaluate the effects of CCog extract in ethylene glycol (EG)-induced nephrolithiasis model in rats. METHODS: The study group comprised 32 Wistar albino rats which were divided into Control (C), EG, CCog Prophylaxis (CC+EG+CC), and CCog Treatment (EG+CC) groups. Stone formation was induced by adding EG (0.75%) into rat’s drinking water. Normal drinking water was given to Control group for 8 weeks. Throughout the study period of 8 weeks, EG group was given only EG (0.75%) and CC+EG+CC group was given both EG and CCog. In EG+CC group, EG (0.75%) was given for 8 weeks whereas CCog was given for the past 4 weeks. After the 8th week, 24-h urine samples were collected. Rats were then sacrificed and kidney tissue samples were harvested. RESULTS: Metabolites (calcium, citrate) and creatinine in 24 h urine samples were decreased in CC+EG+CC and EG+CC groups. While hyperoxaluria was observed in the EG group, oxalate levels were similar to control levels in the P-CCog and C-CCog groups. The N-acetyl-β-glucosaminidase and myeloperoxidase activities were both increased in EG group and these parameters were significantly decreased on CCog treatment. CONCLUSION: We can conclude that C. coggygria extract can have beneficial effect on lowering concentration of stone-forming metabolites in urine and consequently protect renal tissues from damage due to nephrolithiasis. C. coggygria extract can be considered as a potential prophylactic and therapeutic option in high-risk stone formers. Furthermore, our data confirm ethnobotanical use of CC against nephrolithiasis. © 2023 by Istanbul Provincial Directorate of Health.
