To elucidate the role of spleen and splenic allograft in lipid control evaluate its effect on profile rats.32 male Wistar rats were randomly assigned into four groups: group (1), total splenectomy (2), implantation (3) double (4). Each was subdivided two subgroups: A B, based death animals after 30 or 120 days monitoring. The procedures groups 2, 3 4 made simultaneously, splenectomized animals, 2 donors, respectively, for 4. In preserved received implants from spleens 3. regeneration tissue...
Purpose: To compare the continuous and interrupted suture technique on femoral artery rats after vessel repair 14 days after. Methods: Twenty were operated randomly divided into two group matched according to used: or continuous. We performed a anastomosis right artery. analyzed weight, arterial caliber, time patency Results: There was no significant difference between groups in weight (p=0.64), diameter of (p=0.95) (p=1.00). The spent 451 seconds 718 group, presenting (p<0.01). Conclusion:...
Although all microsurgeries are based on the use of surgical microscopes, several alternative magnification systems have shown promising results. Improvements in image quality facilitated video with safety and accuracy. The aim this study was to evaluate a low-cost, video-assisted system peripheral neurorrhaphy rats.Twenty Wistar rats were randomly divided into 2 matched groups according used: microscope group, performed under an 40×; procedures composed high-definition Sony camcorder...
Smartphone cameras are continuously improving. The present study aimed to evaluate the possibility of using smartphones' magnification system perform microanastomosis in rats.Fifteen rats were randomly divided into 3 groups, according used: Microscope, iPhone 7 smartphone, and Galaxy S7 smartphone. In microscope group, a DFVasconcelos microsurgery was used. both smartphone magnifications systems connected 55-inch television through mirror function. Animals groups underwent femoral artery...
Purpose: To develop a new low-cost, easy-to-make and available training model using chickens’ intestine for infant intestinal anastomosis. Methods: Segments of chicken were used to create an anastomosis simulator. We tried perform end-to-end, end-to-side side-to-side Handsewn sutured performed in single layered with interrupted prolene 5-0 suture. The parameters analyzed cost, intestine's diameter length, patency flow-through leakage amount. Results: In all cases it was possible make the...
Resumo Anastomoses vasculares são procedimentos comuns realizados por grande parte dos cirurgiões e cujo treinamento ocorre principalmente em seres humanos, contrariando os princípios éticos vigentes. Esse fato se deve, sobretudo, à carência ao alto custo relacionados aos atuais modelos de treinamento. Assim, este estudo visa avaliar a viabilidade três vegetais para realização anastomoses vasculares. Foram utilizadas cinco unidades cebolinha, vagem feijão-verde. Em cada uma tentou-se...
To verify the publication rate of abstracts presented at XII Brazilian Congress Experimental Surgery.
The laboratory of experimental surgery represents one the key points for university, especially in biomedical area. This focuses on university's tripod primary structure that are teaching, research and extension, which essential formation humanistic practice a good doctor is based, first all, scientific evidence critical knowledge. importance centers medical education was regulated from new curriculum guidelines Ministério da Educação e Cultura, establishing mandatory within college centers....
PURPOSE: To describe a new model to passive smoking for rodents. METHODS: Twenty rats were distributed into two study groups (N=10): control group (CG), that was not exposed tobacco smoke and used as normal standard biochemical histological analysis; Experimental Group (EG), Animals the smoking; Euthanasia performed after 14 days of exposure. The serum level nicotine analysis performed. RESULTS: There statistical difference on levels between Control group, with 286 ±23 nanograma/mL in EG...
The right femoral vessels of 80 rats were identified and dissected. External lengths diameters arteries veins measured using either a microscope or video magnification system. Findings correlated to animals' weights. Mean length was 14.33 mm for both veins, mean diameter 0.65 0.81 mm. In our sample, rats' body weights only with the their veins.Os vasos femorais de ratos foram identificados e dissecados. O comprimento o diâmetro externo da artéria veia mensurados com auxílio um microscópio...
Purpose: To evaluate if combination of perconditioning and postconditioning provides improved renal protection compared to alone in a model reperfusion injury. Methods: Thirty rats were assigned into 6 groups: normality; sham; ischemia reperfusion; postconditioning; perconditioning; + postconditioning. Animals subjected right nephrectomy left for 30 minutes. Postconditioning consisted 3 cycles 5 min perfusion followed by after major ischemic period. Perconditioning hindlimb contemporaneously...
Purpose: To verify the influence of oophorectomy on lipidogram and glycemia. Methods: Fifty six female rats were divided into following 7 groups (n = 8): group 1 - sham group, 2 30 days, 3 35 4 40 5 45 6 70 55 days. Animals by number days according group. Was evaluated serum levels glucose lipid profile. Results: The oophorectomized presented higher Groups 3, 4, had a glycemia LDL (except for 6) lowest HDL. Group highest level VLDL than groups. There was no difference in triglycerides...
