Iloprost reduces colonic injury in ischemic colitis in rats Iloprosta reduz o dano colônico na colite isquêmica em ratos

PURPOSE: Evaluate the effects of iloprost administration in the early period of ischemic colitis and the mechanism that how these effects develop. METHODS: Thirty two Wistar albino female rats with an average weight of 220g were divided into four groups of eight rats. In group 1 the rats were given iloprost and sacrificed after 24 hours and in group 2 they were sacrificed after 24 hours without any iloprost. The rats in group 3 were administrated iloprost and sacrificed after 72 hours and in group 4 they were sacrificed at 72th hour without iloprost. The differences between the groups as tissue damage, vascularization or apoptosis were assessed statistically. RESULTS: Oxidative damage and apoptosis were less pronounced and vascularization was better developed in rats that were given iloprost and sacrificed at 24th hour later in contrast to the rats that were not treated with iloprost. But there was no statistical difference among the groups at 72th hour. CONCLUSION: Iloprost inhibited leucocyte infiltration, decreased proinflammatory cytokines and enhanced angiogenesis so that the oxidative stress and inflammatory response decreased resulting in lesser tissue damage.<br>OBJETIVO: Avaliar os efeitos da administração de iloprosta no período precoce da colite isquêmica e o mecanismo da evolução destes efeitos. MÉTODOS: Trinta e dois ratos Wistar fêmeas em torno de 220g foram distribuídos em quatro grupos de oito ratos. No grupo 1 administração de iloprosta e sacrificados após 24 horas; no grupo 2 foram sacrificados após 24 horas sem iloprosta; no grupo 3 foi administrado iloprosta e sacrificados após 72 horas; no grupo 4 foram sacrificados após 72 horas sem Iloprosta. As diferenças entre os grupos no referente a dano tecidual. vascularização ou apoptose foi apurada estatisticamente. RESULTADOS: Dano oxidativo e apoptose foram menos acentuados e a vascularização foi melhor nos ratos que receberam iloprosta e sacrificados após 24 horas em contraste com os ratos que não receberam iloprosta. Porém, não houve diferença estatisticamente significante entre os grupos de 72 horas. CONCLUSÃO: Iloprosta inibe infiltração leucocitária, diminui a ação inflamatória de citoquinas e estimula angiogênese resultando em menor dano tecidual

Methods: This multicenter study was carried out between January 01 and April 15, 2015 in Turkey in 57 centers. Adults were enrolled and studied in three groups. Group 1: Inactive HBsAg carriers, Group 2: CHB patients receiving antiviral therapy, Group 3: CHB patients who were neither receiving antiviral therapy nor were inactive HBsAg carriers. Study data was collected by face-to-face interviews using a standardized questionnaire, Short Form-36 (SF-36) and Hepatitis B Quality of Life (HBQOL). Values equivalent to p < 0.05 in analyses were accepted as statistically significant. Results: Four thousand two hundred fifty-seven patients with CHB were included in the study. Two thousand five hundred fifty-nine (60.1 %) of the patients were males. Groups 1, 2 and 3, consisted of 1529 (35.9 %), 1721 (40.4 %) and 1007 (23.7 %) patients, respectively. The highest value of HRQOL was found in inactive HBsAg carriers. We found that total HBQOL score increased when antiviral treatment was used. However, HRQOL of CHB patients varied according to their socio-demographic properties. Regarding total HBQOL score, a higher significant level of HRQOL was determined in inactive HBV patients when matched controls with the associated factors were provided. Conclusions: The HRQOL score of CHB patients was higher than expected and it can be worsen when the disease becomes active. Use of an antiviral therapy can contribute to increasing HRQOL of patients
