- Red propolis reduces inflammation in cyclophosphamide-induced hemorrhagic cystitis in rats Nayanna de Oliveira Ramos Melo Helio De Sousa Peres Júnior Clara Araujo Diniz Matheus De Sousa Silva Telma Leda Gomes de Lemos Francisco Vagnaldo Fechine Jamacaru Conceição Aparecida Dornelas Medicina models animal Cystitis propolis cyclophosphamide Introduction. Cyclophosphamide (CP) is used to treat malignant neoplasias and control autoimmune diseases. Still, one of its metabolites, acrolein, is toxic to the urothelium and can lead to hemorrhagic cystitis and severe discomfort.Objective. To evaluate the ability of red propolis to prevent and treat CP-induced hemorrhagic cystitis in rats.Materials and methods. Red propolis was extracted in 1% gum arabic and administered subcutaneously (sc). In the first experiment, groups IA, IIA, and IIIA and groups IB, IIB, and IIIB received water, gum arabic (GA), or propolis, respectively, for 30 days. Then water (controls) or CP (treatment) was administered i.p. In the second experiment, groups IVA, VA, and VIA received water i.p. while groups IVB, VB, and VIB received CP i.p. This was followed by 5 injections at 2-hour intervals with either water, GA, or propolis. Bladder tissue was examined according to Gray’s criteria. Results. The total inflammatory histology score was significantly smaller in group VIB (11.33 ± 2.07). Mild inflammation predominated in group VIB while most of the animals in group IVB had severe inflammation (p=0.0375). Ulcers were predominantly multiple in Groups IVA and VB but rare or absent in Group VIB (p=0.0118). Urothelial cells were mostly absent in groups IVB and VB and present/normal in group VIB (p=0.0052). Fibrin was abundant in groups IVB and VA but mostly absent in group VIB (p=0.0273). Conclusions. Red propolis can reduce inflammation in CP-induced hemorrhagic cystitis in rats. 2022 artículo científico 0120-4157 https://www.redalyc.org/articulo.oa?id=84372632006 https://www.redalyc.org/journal/843/84372632006/ https://www.redalyc.org/journal/843/84372632006/html/ https://www.redalyc.org/journal/843/84372632006/84372632006.epub https://www.redalyc.org/journal/843/84372632006/movil 10.7705/biomedica.6087 en http://www.redalyc.org/revista.oa?id=843 Biomédica application/pdf Instituto Nacional de Salud Biomédica (Colombia) Num.2 Vol.42
