Resumo: | Due to the high incidence of hypomagnesemia in some countries and the absence of studies in Brazil, we want to evaluate the concentrations of magnesium in the vitreous humor of slaughtered bovines in the state of Rio de Janeiro in early spring, aiming to investigate the occurrence of animals under conditions of clinical hypomagnesemia. A total of 116 eyes of adult bovines of different ages and breeds were evaluated. We extracted an eye of each animal to evaluate, immediately after the slaughter and were manipulated to obtain the vitreous humor, under appropriate temperatures conditions. The vitreous humor was collected by aspiration with a 27x7 mm needle, inserted in the lateral corner of the eye. Approximately 1.0 ml of liquid was centrifuged (3000rpm, 15 minutes), the supernatant aspirated with a disposable micropipette, packaged in eppendorfs tubs without preservatives was kept at -20 °C. Tests were performed to determine magnesium concentrations using commercial kits in spectrophotometer automatic digital. The mean of the values obtained (1.99±0.3 mg/dL) was normal or low according to the source consulted. In 66 animals (56,9%) the concentration of magnesium in the vitreous humor was lower, 2.02 mg/dL, indicative of hypomagnesemia, demonstrating a high probability condition of clinical hypomagnesemia (tetany) can develop in the conditions outlined in the present study. The possibility of making a post-mortem diagnosis through vitreous humor analysis is important for the prevention of these diseases and to search for curative measures in those risky areas. |

Foram avaliados olhos de 116 bovinos adultos. Os olhos, um de cada animal, foram obtidos imediatamente após a morte e manipulados para obtenção do humor vítreo, em ambiente refrigerado. O vítreo foi colhido por aspiração com agulha calibre 27x7 mm, inserida no canto lateral do olho. Aproximadamente 1,0 ml do líquido foi centrifugado a 3000g, por 15 minutos. O sobrenadante foi aspirado com pipeta descartável, acondicionado em frascos sem conservantes e mantido a -20 °C. Foram realizados ensaios para magnésio utilizando-se kits comerciais em espectrofotômetro digital automático. A média dos valores obtidos (1,99±0,3 mg/dL) foi normal ou baixa segundo a fonte consultada. No humor vítreo de 66 animais (56,9%) a concentração do magnésio foi menor que 2,02 mg/dL, indicativo de hipomagnesemia, configurando uma condição de alta probabilidade de a hipomagnesemia clínica (tetania) ocorrer nas condições do presente estudo. A possibilidade de realizar o diagnóstico post-mortem por meio da análise do humor vítreo é importante para a adoção de medidas preventivas e/ou curativas em rebanhos em condições de risco.Sociedade de Medicina Veterinária do Estado do Rio de Janeiro.2018-05-20info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionpeer reviewedAvaliado pelos paresapplication/pdfhttps://rbmv.org/BJVM/article/view/9910.29374/2527-2179.bjvm009917Brazilian Journal of Veterinary Medicine; Vol. 39 No. 4 (2017); 264-269Revista Brasileira de Medicina Veterinária; v. 39 n. 4 (2017); 264-2692527-21790100-2430reponame:Brazilian Journal of Veterinary Medicineinstname:Sociedade de Medicina Veterinária do Estado do Rio de Janeiro (SOMVERJ)instacron:SBMVporhttps://rbmv.org/BJVM/article/view/99/775Perez, Fátima I.
