“…The spinal cord ends within S2 in 79% of rabbits, S1 in 19%, and S3 in 2% or rabbits (Greenaway et al, 2001). However, the number of vertebrae can vary, with 44% of rabbits having 12T/7L, 33% having 13T/6L, and 23% with 13T/7L.…”

“…Em coelhos foi registrado a presença de seis a sete nervos espinais lombares e quatro nervos espinais sacrais com localização restrita a região lombar da coluna vertebral, apesar de a medula espinal terminar na região sacral da coluna vertebral (Greenaway et al 2001).…”

Resumo: Um cadáver macho, adulto de irara (Eira barbara) foi cedido pelo Centro de Triagem de Animais Silvestres (Cetas), localizado em Salvador/Bahia, ao Setor de Anatomia Veterinária da Escola de Medicina Veterinária e Zootecnia da Universidade Federal da Bahia. Trata-se de um mamífero carnívoro que pertence à Família Mustelidae e Subfamília Mustelinae que contém o Gênero Eira, representado apenas pela Espécie Eira barbara. Objetivamos a investigação da topografia vertebromedular do espécime e assim verificar a relação da medula espinal com o canal vertebral; a identificação, origem, emergência e quantificação dos nervos espinhais relacionados com a medula espinal. Pesquisa número 43245-1 autorizada pelo Sistema de Autorização e Informação em Biodiversidade (Sisbio-ICMBio/IBAMA). O exemplar foi fixado em solução de formaldeído a 10% e posteriormente dissecado e radiografado. Foram identificados oito pares de nervos espinhais cervicais, quatorze torácicos e na porção lombossacral da medula espinhal seis nervos espinais lombares, três sacrais e mais de três nervos espinhais caudais. O término da medula espinal ocorreu no nível quinta vértebra lombar. Os oito segmentos medulares cervicais localizaram-se entre a primeira e sétima vértebras cervicais. Os quatorze nervos espinais torácicos originaram-se na porção cranial das vértebras respectivas. Os segmentos medulares lombares, sacrais e caudais restringiram-se à região lombar da coluna vertebral. O deslocamento cranial dos segmentos medulares foi observado no oitavo cervical, terceiro, quarto e quinto lombares e todos os segmentos sacrais e caudais. As informações obtidas poderão ser utilizadas para análises comparativas com as demais espécies e com a adoção de medidas que visem proporcionar o bem-estar animal e a preservação da espécie.

“…A total of 45 young adult male rabbits from the Botucatu Genetic Group breed, weighing between 3300 g and 5400 g, with spinal cord length (measured from the base of the skull to the lumbosacral space)9 between 38 cm and 41 cm were included in the study. The Animal House at Botucatu Medical School provided the rabbits.…”

Background and objectivesAs the number of people with tattoos has been increasing, anesthesiologists are more and more faced with the decision to perform a neuraxial blockage through tattooed skin. In this study, we evaluated the possibility of puncture through tattooed skin determines acute inflammatory changes in the meninges and spinal cord and later evolve into adhesive arachnoiditis.MethodForty-two male rabbits were randomized into 3 groups of 14: G1, spinal puncture through non-tattooed skin and saline solution injection; G2, spinal puncture through tattooed skin and saline solution injection, captive for 30 days; G3, spinal puncture through tattooed skin and saline solution injection, captive for 360 days. The animals were anesthetized and ultrasound-guided spinal puncture was performed in the intervertebral spaces between S1 – S2. During the period of captivity, the animals were clinically assessed for sensitivity and motor function. After that, they were sacrificed and the lumbosacral portion of the spinal cord was excised for histological analysis.ResultsNo histological changes were found on group 1. Eleven animals from group two presented with foci of perivascular lymphocytic inflammatory infiltrate in the pia mater and/or arachnoid. In Group 3, eight rabbits presented with inflammatory changes in the meninges, which were associated with thickening and/or adhesion of the pia mater and arachnoid in some cases and five rabbits presented only thickening of pia-mater.ConclusionsSpinal puncture through tattooed skin of rabbits can trigger acute inflammatory changes in the meninges and after a prolonged period of observation evolve into adhesive arachnoiditis.
