Visceral collateral branches of the abdominal aorta in New Zealand rabbits (Oryctolagus cuniculus) / Ramos colaterais viscerais da aorta abdominal em coelhos da raça Nova Zelândia (Oryctolagus cuniculus)

Background: Rabbits (Oryctolagus cuniculus) are lagomorphs belonging to the Leporidae family. They are widely used in laboratory experiments and are an important source for humans feeding industry. In the biomedical investigation field, the rabbit contributes for the production of several scientific studies. Since studies about the rabbits morphology is rare, especially what refers to abdominal vascularization, this work had the objective to systematize and describe the visceral collateral branches of the abdominal aorta in New Zealand rabbits. Materials, Methods & Results: Fourteen male and sixteen female New Zealand young adult rabbits (Oryctolagus cuniculus) were used. Animals were euthanized with T 61, administered via an intrapulmonary injection. Skin was removed, thoracic cavity opened in plastron, thoracic aorta cannulated, according to blood flow, and the two cranial and caudal cava veins sectioned near the heart. System was washed with saline solution and heparin and filled with red latex. Animals remained immersed in running water, for 90 min, and the trunk was transversally sectioned, near the last thoracic vertebra. The abdominal cavity remained closed and formaldehyde was administered via an intraperitoneal injection. Samples were fixed in formaldehyde for seven days, the abdominal cavity opened, the viscera removed in block and the arteries dissected. Schemat

O coelho doméstico (Oryctolagus cuniculus) é um lagomorfa da família Leporidae originado dos coelhos selvagens da região oeste da Europa e noroeste da África. É considerado um animal convencional de laboratório, utilizado em quase todas as áreas da investigação biomédica, contribuindo, dessa forma, para diversos estudos científicos e constitui uma importante fonte de proteína animal para a alimentação humana.

Anatomical techniques as a complementary method for learning nephrotomy / Técnicas anatômicas como método complementar para aprendizado de nefrotomia

Background: The use of animals in attempt to understand biological processes began many years ago with Hippocrates (450 B.C.). Galeno (129-210 a.C.) studied the anatomy and physiology of the monkeys, believing in their similarity to humans. The use of animals in experiments has always been the target of too much criticism by several society segments, questioning animal suffering after manipulation. This is due to the fact that students and professors consider that such practices are against their moral and ethical principles, besides the psychological issues that they can promote. Because of this, alternative and complementary methods were developed for surgical training and motor development of surgeons, with the goal to reduce the number of animals in these practices and to increase qualifi cation and surgical skills. The objective of this study is to offer a complementary method of learning in the area of surgery, specifi cally anatomical techniques as a complementary method for learning nephrotomy.Materials, Methods & Results: Four dog kidneys were used from the pathology sector of the Universidade Federal do Rio Grande do Sul. The kidneys were removed from the abdominal cavity with the perirenal fat, blood vessels and ureter. The renal artery, renal vein and ureter were cannulated and fi lled with red, blue and yellow colored latex, respectively. After this, the kidney
