“…Due to the nonspecific binding of plasma conjugates, quantification of cytokine proteins by ELISA has less certainty and the level of cytokine proteins in plasma is lower than that of their corresponding mRNA ( Li et al, 2022 ). Furthermore, ELISA cannot be used to measure the cytokines stored intracellularly.…”

Background: Ulcerative colitis is a chronic immune-mediated inflammatory bowel disease that involves inflammation and ulcers of the colon and rectum. To date, no definite cure for this disease is available.Objective: The objective of the current study was to assess the effect of Calliandra haematocephala on inflammatory mediators and oxidative stress markers for the exploration of its anti-ulcerative colitis activity in rat models of acetic acid-induced ulcerative colitis.Methods: Methanolic and n-hexane extracts of areal parts of the plant were prepared by cold extraction method. Phytochemical analysis of both extracts was performed by qualitative analysis, quantitative methods, and high-performance liquid chromatography (HPLC). Prednisone at 2 mg/kg dose and plant extracts at 250, 500, and 750 mg/kg doses were given to Wistar rats for 11 days, which were given acetic acid on 8th day through the trans-rectal route for the induction of ulcerative colitis. A comparison of treatment groups was done with a normal control group and a colitis control group. To evaluate the anti-ulcerative colitis activity of Calliandra haematocephala, different parameters such as colon macroscopic damage, ulcer index, oxidative stress markers, histopathological examination, and mRNA expression of pro and anti-inflammatory mediators were evaluated. mRNA expression analysis was carried out by reverse transcription quantitative real-time polymerase chain reaction (RT-qPCR).Results: The phytochemical evaluation revealed polyphenols, flavonoids, tannins, alkaloids, and sterols in both extracts of the plant. Results of the present study exhibited that both extracts attenuated the large bowel inflammation and prevented colon ulceration at all tested doses. Macroscopic damage and ulcer scoreswere significantly decreased by both extracts. Malondialdehyde (MDA) levels and nitrite/nitrate concentrations in colon tissues were returned to normal levels while superoxide dismutase (SOD) activity was significantly improved by all doses. Histopathological examination exhibited that both extracts prevented the inflammatory changes, cellular infiltration, and colon thickening. Gene expression analysis by RT-qPCR revealed the downregulation of pro-inflammatory markers such as tumor necrosis factor-alpha (TNF-α) and cyclooxygenase-2 (COX-2) whereas the anti-inflammatory cytokines including Interleukin-4 (IL-4) and Interleukin-10 (IL-10) were found to be upregulated in treated rats.Conclusion: It was concluded based on study outcomes that methanolic and n-hexane extracts of Calliandra haematocephala exhibited anti-ulcerative colitis activity through modulation of antioxidant defense mechanisms and the immune system. In this context, C. haematocephala can be considered as a potential therapeutic approach for cure of ulcerative colitis after bioassay-directed isolation of bioactive phytochemicals and clinical evaluation.

Abstract. Rayimova F, Dushanova G, Alikulov B, Kamalov Z, Ruzibakieva M, Nabiyeva F, Rajabov A. 2024. The role of VDR and TNF gene polymorphism in cytokine regulation in type I diabetes mellitus of the Uzbek population, Samarkand, Uzbekistan. Biodiversitas 25: 1329-1336. After 2000, diabetes became one of the most common diseases in the world. Special attention is paid to the research to determine the variability of genetic processes in patients in the origin and development of this disease. The article is devoted to the study of the connection between the polymorphism of genotypes GG, GA, AA polymorphism BsmI of the VDR- (Vitamin D receptor) gene and GG, GA of the TNF-A-308G/A- (Tumor necrosis factor A) gene with the regulation of cytokines TNF? and IL6-Interleykin 6 in sick and healthy individuals of the Samarkand region of the Uzbek population. The analysis of the BsmI polymorphism of the VDR gene and TNF-A-308G/A indicates the involvement of certain genotypes in the Type 1 Diabetes Mellitus (T1DM) pathogenesis. The age of onset of the disease in the studied population is from 7 years, but the increase in the incidence of diseases begins from 10 years. Type 1 diabetes is more common in females. Studies of the relationship between the cytokines TNF? and IL6 show their high content depending on the genotypes GG, GA, and AA of the BsmIA polymorphism of the VDR gene and the genotypes GG and GA of the gene. TNF-A-308G/A. However, the highest rates were recorded in individuals with the AA genotype of the BsmI polymorphism of the VDR gene. The obtained results can serve as fundamental knowledge in revealing and explaining the mechanisms of cytokinin control in people with diabetes in different populations of the same nation.
