RESUMEN

Intensely eosinophilic and glassy intracytoplasmic inclusions were present in the neurons of the peripheral autonomic ganglia, Meissner's and Auerbach's plexus, and spinal ganglia in 20 aged white-nosed coatis ( Nasua narica, 7-19 years old) and in 4 of 7 brown-nosed coatis ( Nasua nasua, 2-21 years old) from multiple zoological institutions. Inclusions were single to numerous, sometimes distorting the cell. Pheochromocytomas were present in 5 of 16 white-nosed and 2 of 6 brown-nosed coatis, although no inclusions were present in the adrenal glands. Histochemically, immunohistochemically, and ultrastructurally, these inclusions were consistent with dense neurosecretory granules. Although similar inclusions have been reported sporadically in the adrenal medulla of humans and several other mammalian species as both incidental and pathologic findings, ganglionic inclusions reported herein appear to be unique and related to age in these species.

RESUMEN

We describe the use of a combination of tiletamine and zolazepam (Zoletil®) for chemical restraint of South American coatis ( Nasua nasua ) under field conditions. We immobilized 53 coatis from a free-ranging population at Iguaçu National Park, Brazil, with Zoletil. Males and females (1.0-8.7 kg) of different age groups participated in the study. Four dosage (milligram per kilogram body weight) groups were created based on quartiles as follows: 1) 4.76-6.68 mg/kg (n=13), 2) 6.83-7.71 mg/kg (n=13), 3) 7.72-8.68 mg/kg (n=18), and 4) 8.98-11.57 mg/kg (n=9). Variables analyzed were sex, age, body weight, dosage, induction time, handling time (HT: time elapsed between the onset of immobilization and first signs of recovery), time from injection to first stand-up posture after anesthesia, heart and respiratory rates, and body temperature. Mean (±SD) induction time was 2.9 (±1.4) min and was positively correlated with age. In dosage groups 1-4, mean HTs were 40.3 (±24.0), 64.5 (±19.1), 54.8 (±15.0), and 60.3 (±12.0), respectively. Handling time had a positive linear relationship with age and body weight, but the relationship between HT and dosage was nonlinear. Group 1 had a shorter HT compared to the other groups combined. Time from injection to first stand-up was 105.0 (±33.5) min. Zoletil was quick acting and safe for immobilization of coatis in the wild.

RESUMEN

Onze quatis (Nasua nasua), de ambos o sexos e idades variadas, clinicamente sadios, mantidos em cativeiro no Horto Botânico de Niterói e no Zoológico Municipal de Volta Redonda, foram utilizados para colheita de amostras sangüíneas, visando a realização de exames hematológicos. Estes exames consistiram na determinação de hemograma, dosagens séricas de glicose, uréia, creatinina, proteínas totais, albumina, globulinas, aspartato-aminotransferase (AST), alanina-amino-transferase (ALT) e colesterol, além de pesquisa de hemoparasitas. As amostras foram obtidas por punção das veias cefálica e/ou femural, e processadas no Laboratório de Patologia Clínica da Faculdade de Veterinária da Universidade Federal Fluminense. Os valores médios encontrados foram: hemácias = 5,5 x 106 /mm3; volume globular = 33,5%; hemoglobina= 11 g%; volume globular médio = 61,9 fi; concentração de hemoglobina globular média = 32,1 %; leucócitos = 8950/mm3; basófilos = 0%; eosinófilos = 10%; bastões = 0%; segmentados = 56%; linfócitos = 30%; monócitos = 3%; proteínas totais = 9,4 g%; albumina= 3,8 g%; globulinas = 5,6 g%; ALT = 31,1 UI; AST = 47 UI; glicose = 11 O mg/dl; uréia= 25 mg/dl; creatinina = 0,7 mg/dl; colesterol= 288 mg/dl. Não foram encontradas hemoparasitas nas amostras examinadas. Concluiu-se que estes valores são semelhantes aos relatados na literatura para canídeos domésticos e outros procionídeos, como o guaxinim (Procyon sp.). Não houve influência significativa nos valores obtidos com diferentes métodos de contenção.

Eleven coatimundis (Nasua nasua) of both sexes and various ages, clinically healthy, kept in captivity at "Horto Botânico de Niterói" and "Zoológico Municipal de Volta Redonda", were used for collecting of blood samples for hematological examination: hemogram, serum dosages of glucose, urea, creatinine, total protein, albumin, globu-lins, aspartate aminotranferase (AST), alanina aminotransferase (ALT) and cholesterol, and also hemoparasites research. The samples were obtained by punction of cephalic or femoral veins and were carried out at the Laboratory of Clinicai Pathology, Faculty of Veterinary, Fluminense Federal Universíty. The following mean values were found: erythrocítes = 5,5 x 1 06 /mm3; packed cell volume= 33.5%; hemoglobin = 11 g%; mean corpuscular volume = 61,9 fl; mean corpuscular hemoglobin concentration = 32.1 %; leukocytes = 8950/mm3; basophíls = O; eosinophils = 1 0%; neutrophils =56%; lymphocytes = 30%; monocytes = 3%; total protein = 9.4 g%; albumin = 3.8 g%; globulins = 5.6 g%; AST = 47 UI; ALT = 31.1 UI; glucose = 110 mg/dl; urea = 25 mg/dl; creatinine = 0.7 mg/dl; and cholesterol = 288 mg/dl. No hemoparasítes were found in the samples. We concluded that these values were similar to those described to domestic Canidae and other Procyonidae, like the racoon Procyon sp. lt was not found any meaningful influence in the values obtained when were used different handling methods.
