    Efeitos do clampeamento do pedículo hepático nos intestinos
    (Sociedade Brasileira para o Desenvolvimento da Pesquisa em Cirurgia, 2000-03-01) Sébe, Abrão Antonio; Nigro, Amaury José Teixeira [UNIFESP]; Gomes, Paulo de Oliveira [UNIFESP]; Simões, Manuel de Jesus [UNIFESP]; UNIC; Universidade Federal de São Paulo (UNIFESP)
    It was made a clamping of the hepatic pedicle in different lapses of time and the morphological features of this intestines were observed. 40 male rats were divided in four groups of 10 animals each. The group S (Sham) was not submitted to ischemia and the groups E1, E2 and E3 suffered ischemia during 10, 20 and 30 minutes respectively. Our results showed macroscopic modifications related to the colour of the intestines in the groups E2 (20') and E3 (30') as well as histopathological changes in the same groups. It was also observed that the larger the lapse of time of clamping of the hepatic pedicle the larger was the splanchnic congestion and in the group 30' detachment of the lining epithelium was observed in the intestinal villi.

    Estudo do reparo do ferimento de colon com o lado seroso da parede de jejuno, utilizando cianoacrilato e cola de fibrina
    (Colégio Brasileiro de Cirurgiões, 2006-04-01) Fontes, Carlos Edmundo Rodrigues; Taha, Murched Omar [UNIFESP]; Fagundes, Djalma José [UNIFESP]; Prado Filho, Orlando; Ferreira, Marcos Victor; Mardegan, Marino José; Universidade Estadual de Maringá Clínica Cirúrgica; Universidade Federal de São Paulo (UNIFESP)
    BACKGROUND: The present experiment aimed to compare the effect of the use of cyanoacrylate and fibrine glue as adesive on repared colon's wounds with the serosal side of jejuno's wall. METHODS: Forty five male, young adult Wister rats, weighting about 260 g , from the University of Maringá were used.After having been deeply anaesthetized (thiopental was used), the animals underwent a surgery, and a pattern 0,5 cm wound was made, 2 cm away from the cecum, in the caudal location. Group one the wound was repaired by using the jejunal serosal wall and suture.On group two the jejunal serosal wall and fibrine glue was used. Finally on group three the repair was made by using the jejunal serosal wall and cyanoacrylate. The animals were submited to roentgenogram with barium enema on the fourth postoperative day to search for stenosis. On the seventh day, after having been anaesthetized, animals were submited to a laparotomy, segments were collected for both macroscopic and microscopic study. RESULTS: Fibrine glue has shown better result on repair, due to the production of collagen fibres. CONCLUSION: The experiment has come to prove that the wound made on rat's colon can be repaired by the jejunal serosal wall joined to the wound either using the fibrine glue or cyanoacrylate.

    The role of ischemic preconditioning and pentoxifylline in intestinal ischemia/reperfusion injury of rats
    (Acta Cirurgica Brasileira, 2017) Ribeiro de Oliveira, Teresinha Regina [UNIFESP]; de Oliveira, Geraldo Ferreira; Simoes, Ricardo Santos [UNIFESP]; Tikazawa, Eduardo Hiroshi; Monteiro, Hugo Pequeno [UNIFESP]; Fagundes, Djalma Jose [UNIFESP]; Taha, Murched Omar [UNIFESP]
    Purpose: To investigate the role of ischemic preconditioning (IPC) and pentoxifylline (PTX) in intestinal mucosa ischemia/reperfusion injury (IR). Methods: Thirty rats were assigned to 5 groups (N= 6): (CG): no clamping of the superior mesenteric artery (90 min.)
