“…As artérias renais podem diferir de acordo com a distribuição e o arranjo, podendo apresentarse únicas ou múltiplas, nos achados em catetos (MACHADO et al, 2000), suínos (FERREIRA, 1975;FAGUNDES, 1984;SAMPAIO et al, 1996;SOUZA, 1997;VODENICHAROV;DANCHEV, 2003), caprinos (ALBUQUERQUE, 1979;ASLAN;NAZLI, 2001), caprinos mestiços (CARVALHO, 1995), pequenos ruminantes (PEDUTI- NETO, 1976;CARVALHO;PEREIRA, 1987), cães (ARNAUTOVIC, 1959;CORREIA;ESPERANÇA-PINA, 1982), cachorro do mato (MENEZES et al, 2011), rato (GREENE 1963, coelhos (BARONE, 1997), hamster dourado (VILARTA et al, 1982a), capivaras (SOUZA et al, 1996), queixadas (ROMAGNOLLI et al, 2008) As artérias renais em sua primeira divisão originam duas artérias setoriais, a artéria setorial dorsal e a artéria setorial ventral. Diversos autores confirmam a presença da bifurcação originando os mesmo ramos, em cão (MARQUES, 1998), coelho (MOURA; SANTOS, 2006); cutia (CARVALHO et al, 2008);javali (VODENICHAROV;DANCHEV, 2003); ovinos (PEDUTI NETO, 1976) caprinos (ALBUQUERQUE, 1979;CARVALHO et al, 1998), sendo o mesmo constatado em mão-pelada.…”

“…Em catetos (MACHADO et al, 2000) os achados diferem de todos os dados literários citados, pois a artéria renal bifurca-se em três artérias setoriais, sendo designadas de dorsocranial, dorsocaudal e ventral no rim direito e dorsal, ventrocranial e ventrocaudal no esquerdo. Entretanto os resultados encontrados em suínos (FERREIRA, 1975;FAGUNDES, 1984;SAMPAIO et al, 1996; SOUZA, 1997) e queixadas (ROMAGNOLLI et al, 2008), descrevem a divisão das artérias renais em ramos setoriais craniais e caudais, e confirmam a ausência dos ramos setoriais dorsal, dorsocranial, dorsocaudal, ventrocranial e ventrocaudal, que estavam presentes em catetos.…”

ResumoO mão-pelada é um animal de porte médio, cauda longa, amarelada com ponta negra e ornada, apresentando de cinco a dez anéis escuros e amarelados. Habitam em florestas equatoriais e tropicais, sempre próximo a rios, brejos, pântanos e mangues. Utilizaram-se dois exemplares de Procyon cancrivorus, mortos por acidente e, posteriormente, encaminhados ao Laboratório de Anatomia da UFG, campus Jataí, onde a partir das artérias renais foram dissecados os segmentos arteriais com auxílio de um microscópio estereoscópico. Como resultado visualizou-se as artérias renais sempre únicas, bifurcando-se em segmentos dorsais e ventrais, subdividindo em segmentos ventrocranial, ventromédiocranial, ventromédio, ventromédiocaudal, ventrocaudal, dorsocranial, dorsomédiocranial, dorsomédio, dorsomédiocaudal e dorsocaudal igualmente observados em coelhos, cutia, javali e ovinos. Este estudo apresentou um padrão de distribuição arterial igualmente identificado nos rins direitos quanto nos rins esquerdos, o local de penetração das artérias renais coincidem com os achados em camundongos e diferem do rato, hamster dourado e cutia. De acordo com a distribuição e arranjo, a morfologia renal do Procyon cancrivorus é similar à encontrada em animais domésticos e silvestres. O reconhecimento dos ramos arteriais renais apresenta grande relevância tanto para o caso de intervenções cirúrgicas quanto para investigações futuras, que auxiliem o conhecimento sobre essa espécie.

The specimens live in equatorial and tropical forests, always close to rivers, swamps, marshes, and mangroves. Two specimens of Procyon cancrivorus were used, both killed by accident and, later on, sent to the Anatomy Laboratory of Universidade Federal de Goias (UFG), in the Jatai campus, where, starting from the renal arteries, the arterial segments were dissected with the aid of

“…Romagnolli et al 22 analyzed the renal anatomy of the Tayassu pecari and stated that it (Tayassu peccary) belongs to the same family as the collared peccary, Tayassuidae, renal artery is always single, a fact also observed in collared peccary 21 , wild boar (Sus scrofa) 23 that belong to superfamily Suidoidae and the domestic pig 24 .…”

PURPOSE:The use of the collared peccary as an experimental model for ischemic nephropathy. METHODS:A total of 12 collared peccary (Tayassu tajacu) was used and ischemic nephropathy was induced in six of these animals that constituted the experimental group (G1) while the other six formed the control group (G2). Ischemic nephropathy was induced surgically by partial occlusion of the left renal artery. The disease course was assessed by hematological tests, serum chemistry, urinalysis, ultrasound (US) and doppler ultrasound function of the renal artery before induction, and at five, 10, 15 and 20 days after surgery.Twenty days after the occlusion, unilateral nephrectomy and histopathological examination were performed to assess renal morphology. RESULTS:Statistical analysis by Fischer's test showed a significant difference (p<0.05) between the control group and the experimental group. The histopathological examination showed glomerular, tubular and interstitial lesions. In the experimental group, 83.3% (5 /6) showed moderate renal lesions and only 16.7% (1/6) were classified with no lesions. The ultrasound examination of the right kidney presented statistical difference between day 5 and day 10 post occlusion. CONCLUSION:The collared peccary as a good experimental model for ischemic renal disease, because it could be manipulated during the research time without death, with health conditions that permit any subsequent procedure for disease therapy.Key words: Artiodactyla.

249Pesq. Vet. Bras. 28(5): 249-252, maio 2008 RESUMO.-Foram estudados 20 pares de rins de cutias (Dasyprocta prymnolopha Wagler, 1831), com o objetivo de descrever os segmentos anátomo-cirúrgicos arteriais. As artérias renais foram injetadas com solução de Vinilite corada, e os rins foram submetidos à corrosão ácida para a obtenção dos moldes vasculares. Observou-se que as artérias renais da cutia, sempre únicas, dividiram-se em artéria setorial ventral e artéria setorial dorsal, caracterizando dois setores renais separados por plano avascular. As artérias setoriais penetraram no hilo renal (100% dos casos). Estes vasos deram origem aos ramos segmentares responsáveis pela irrigação de territórios independentes em cada setor, os segmentos arteriais renais. No rim direito foram observados 3 (60%), 4 (35%) e 5 segmentos (5%) no setor arterial ventral e 3 (30%), 4 (45%), 5 (20%) e 6 (5%) segmentos no setor dorsal e, à esquerda, 2(10%), 3 (55%) e 4 (35%) segmentos no setor ventral e 3 (25%), 4 (50%) e 5 (25%) no dorsal. Com base na distribuição arterial nos rins de cutia, observaram-se setores e segmentos arteriais independentes, sendo possível, desta ) kidneys were studied to describe the arterial anatomical-surgical segments. The renal arteries were injected with stained acetate vinyl, followed by procedures of acid corrosion in order to obtain vascular casts. It was found that the renal artery is always single and bifurcated into ventral and dorsal sectorial arteries. The sectorial arteries reached the kidneys (100% of the cases) through the hilus. These vessels gave origin to segmental branches responsible for kidney irrigation. At the right kidney, the ventral sectorial arteries gave origin to 3 (60% of the cases), 4 (35%) and 5 (5%) segmental branches; the dorsal sectorial arteries gave origin to 3 (30%), 4 (45%), 5 (20%) and 6 (5%) segmental arteries separated by a vascular sector. At the left kidney, the ventral sectorial arteries originated 2 (10%), 3 (55%) or 4 (35%) segmental branches; the dorsal sectorial arteries gave origin to 3 (25%), 4 (50%) and 5 (25%) segmental branches. Based on the arterial distribution of agouti kidneys, independent sections and arterial segments were found, so that it is possible to accomplish partial kidney resection surgery.
