[Considerations about the branching of the aorta abdominalis in hamster (Mesocricetus auratus) (author's transl)].

This paper deals with the disposition of the abdominal aorta branching in Mesocricetus auratus, stablishing variation groups with relation to the celiac, cranial mesenteric, renal, genital and caudal mesenteric arteries. Sixty animals (30 males and 30 females) of different ages and weights, from the Faculdade de Ciências Médicas e Biológicas de Botucatu, were anesthetized with chloroform, injected with contrasting substance in abdominal aorta (50 animals with Neoprene latex and 10 with radio-opac mass) and dissected through stereoscopic microscope. The animals with radio-opac mass were radiographed in order to compare with other preparations. The results were expressed in relative percentage figures and compared with other mammalian arterial dispositions.
