RESUMO

Abstract Rationale: Disuse colitis is frequent in our country and the most effective treatment is high cost and there is a need for effective and low cost therapy. Objective: To evaluate the efficacy of Baccharis dracunculifolia (field rosemary) in the treatment of exclusion colitis in rats. Method: Eighteen Wistar rats were anesthetized and submitted to colostomy; they were then distributed into two groups: Control Group, receiving intrarectal saline infusion (n = 8) and Group BD receiving intrarectal infusion ofBaccharis dracunculifolia extract (n = 10); after 21 days of treatment they were euthanized, the intestinal segment excluded from intestinal transit was resected and submitted to histopathological study, classifying the degree of inflammation and degree of vascular congestion from 0 to 3. Results: Mean inflammation was 2.7 in Control Group versus 2.1 in BD Group (p = 0.049), while mean vascular congestion was 2.3 and 2, respectively, in Control and BD groups (p = 0.1642). Conclusion: Intra-rectal infusion ofBaccharis dracunculifolia extract significantly minimized the inflammatory process in the exclusion colitis of rats submitted to colostomy, without altering the degree of vascular congestion.


Resumo Racional A colite de desuso é frequente em nosso meio e o tratamento de maior eficácia é de alto custo, havendo necessidade de se encontrar uma terapêutica eficaz e de baixo custo. Objetivo Avaliar a eficácia da Baccharis dracunculifolia (alecrim-do-campo) no tratamento da colite de exclusão em ratos. Método Utilizou-se 18 ratos Wistar, os quais foram anestesiados e submetidos à colostomia; em seguida distribuídos em 2 grupos: Grupo Controle, recebendo infusão intrarretal de solução salina (n = 8) e Grupo BD, recebendo infusão intrarretal de extrato de Baccharis dracunculifolia (n = 10); após 21 dias de tratamento foram submetidos a eutanásia, o segmento intesinal excluso de trânsito intestinal foi ressecado e submetido a estudo histopatológico classificando-se o grau de inflamação e grau de congestão vascular de 0 a 3. Resultados Verificou-se média de inflamação 2,7 no Grupo Controle vs. 2,1 no Grupo BD (p = 0,049), enquanto as médias de congestão vascular foram 2,3 e 2, respectivamente, nos grupos controle e BD (p = 0,1642). Conclusão A infusão intrarretal do extrato de Baccharis dracunculifolia minimizou significantemente o processo inflamatório na colite de exclusão de ratos submetidos à colostomia, sem alterar o grau de congestão vascular.

RESUMO

BACKGROUND: Diversion colitis is still very common in our country, since the stoma creation is a common practice especially in situations of trauma. needing treatment for this condition. AIM: To evaluate the therapeutic effect of rectal infusion of Curcuma longa (turmeric) in the excluded intestinal segment of rats. METHOD: Eighteen Wistar rats were used and submitted to colostomy: control group (n=8) under rectal saline infusion and group CL, receiving intra-rectal infusion of Curcuma longa extract (n=10). After 21 days of treatment they were submitted to euthanasia; the intestinal segment excluded from intestinal transit was resected and sent to histopathological evaluation, classifying the degree of inflammation and of vascular congestion. RESULTS: The average of inflammation was 2.7 in the control group vs. 2.6 in the CL group (p=0.3125), while the mean vascular congestion was 2.3 and 2.1, respectively, in the control and CL groups (p=0.1642). CONCLUSION: Intra-rectal infusion of Curcuma longa extract was not able to minimize the inflammatory process or vascular congestion in the diversion colitis of rats subjected to colostomy.
