ALTERAÇí-ES HEMATOLÓGICAS EM CURIMBATÁ, Prochilodus scrofa STEINDACHNER, 1881, EXPOSTO AO DIPTEREX 500 (TRICHLORFON)

Abstract

Espécimes juvenis de curimbatá, Prochilodus scrofa, foram divididos em dois lotes, colocados em aquários de 81 litros, sendo um controle e outro tratado com Dipterex 500 (Trichlorfon), na concentração de 0,2 µL/L, onde os peixes permaneceram até o final do experimento. Amostras de sangue de cinco exemplares de cada lote foram coletadas 24, 48, 72 horas após o tratamento. O sangue foi utilizado para determinações de número de eritrócitos, hematócrito, taxa de hemoglobina e contagem diferencial dos leucócitos. Calcularam-se os í­­ndices hematimétricos absolutos: Volume Corpuscular Médio (VCM), Hemoglobina Corpuscular Média (HCM) e Concentração de Hemoglobina Corpuscular Média (CHCM). Os espécimes expostos ao Dipterex 500 apresentaram, da primeira para a terceira amostra, queda dos valores médios de hematócrito, número de eritrócitos, taxa de hemoglobina, HCM e CHCM. Os espécimes do lote controle apresentaram valores próximos aos obtidos na primeira coleta, durante todo o experimento. Os linfócitos foram as células brancas mais frequentes no sangue periférico dos indiví­­duos do lote controle, enquanto que os neutrófilos, as mais frequentes nos indiví­­duos expostos ao Dipterex 500. Nos indiví­­duos expostos ao produto notou-se diminuição da porcentagem de linfócitos e monócitos e aumento das porcentagens de neutrófilos e células imaturas, respectivamente da primeira para a terceira amostras. Basófilos só ocorreram nos animais controle e eosinófilos, em ambos os grupos, na terceira amostra.
