Objetivo: determinar a diferença da média de hiperplasia miointimal pós-angioplastia na artéria ilíaca de coelhos tratados e não tratados com extrato das folhas de Moringa oleifera. Métodos: ensaio aleatório em animais de laboratório por cinco semanas de seguimento, desenvolvido no Biotério do Laboratório de Tecnologia Farmacêutica da Universidade Federal da Paraíba. Foram utilizadas coelhas da raça Nova Zelândia, submetidas à dieta hipercolesterolêmica e angioplastia da artéria ilíaca externa, randomizadas em dois grupos: Grupo M200 (n=10), coelhas tratadas com 200mg/kg/dia de extrato de folhas de Moringa oleifera, por via oral; Grupo SF (n=10), coelhas tratadas com soro fisiológico 0,9%, por via oral. Após cinco semanas, os animais foram eutanaziados e as artérias ilíacas preparadas para histologia. Os cortes histológicos foram analisados por morfometria digital. A análise estatística foi realizada com o teste t de Student. O nível de significância foi 0,05. Resultados: comparando as artérias ilíacas submetidas à angioplastia do grupo M200 com as do grupo SF, não houve diferença significativa da hiperplasia miointimal Conclusão: não houve diferença da hiperplasia miointimal nos grupos tratados com soro fisiológico e Moringa oleifera após angioplastia.

Objective: to assess post-angioplasty myointimal hyperplasia in iliac artery of rabbits treated with extract of Moringa oleifera leaves. Methods : we conducted a randomized trial in laboratory animals for five weeks of follow-up, developed in the Vivarium of Pharmaceutical Technology Laboratory of the Universidade Federal da Paraíba. We used rabbits from the New Zealand breed, subjected to a hypercholesterolemic diet and angioplasty of the external iliac artery, randomized into two groups: M200 Group (n=10) - rabbits treated with 200mg/kg/day of Moringa oleifera leaves extract orally; SF group (n=10) - rabbits treated with 0.9% saline orally. After five weeks, the animals were euthanized and the iliac arteries prepared for histology. Histological sections were analyzed by digital morphometry. Statistical analysis was performed using the Student's t test. The significance level was 0.05. Results : there was no significant difference in myointimal hyperplasia between M200 and SF groups when comparing the iliac arteries submitted to angioplasty. Conclusion : there was no difference of myointimal hyperplasia between groups treated with saline and Moringa oleifera after angioplasty.

Cecal volvulus is an uncommon cause of acute bowel obstruction in adults. The mechanism is torsion of the enlarged, poorly-fixed or hypermobile cecum. Patients with this condition may display highly variable clinical presentations, ranging from intermittent, self-limiting abdominal discomfort to acute abdominal pain associated with intestinal strangulation and sepsis. The treatment needs to be individualized for each case, but surgical management is required in almost every case. In the presence of gangrene or perforation of the cecum, resection and primary ileocolic anastomosis is recommended. However, in non-complicated cases detorsion and cecopexy are adequate. The authors report one case of cecal volvulus in a 55-year-old women treated with cecopexy that complicated with septic jaundice.
