ABSTRACT
Channa punctatus was exposed to four different concentrations of Rutin, Taraxerol and Apigenin. Changes in some hematological parameters of Channa punctatus were assessed to determine the influence of these compounds on test fish. Fish were exposed to sublethal concentrations (80 percent of LC50 of 24h) of these compounds for one week. Control fish were also administered for one week. Thereafter, blood samples were obtained from the control and experimental fish. Blood was assayed for selected hematological parameters (hematocrit, hemoglobin, red blood cell count, white blood cell count total plasma protein and plasma glucose concentration). The derived hematological indices of mean corpuscular hemoglobin concentration (MCHC), mean corpuscular hemoglobin (MCH) and mean corpuscular volume (MCV) were calculated. Sublethal concentrations of these compounds caused a dose dependent decrease in hemoglobin values coupled with a decrease in hematocrit values and red blood cell counts are an obvious indication of anemia. The total white blood cell counts and the differential white blood cell counts were decreased except for the lymphocytes, where there was a slight increase. Plasma protein and glucose were also lower in exposed fish when compared with control. The hematological indices MCH, MCHC, MCV were also lowered. The result from this study reveals high mortality rate and deleterious consequences on the health of fish subjected to acute exposure of Rutin, Taraxerol and Apigenin and therefore, should not be used directly in aquaculture without having the proper knowledge.
RESUMO
Channa punctatus foi exposta a quatro diferentes concentrações de Rutina, Taraxerol e Apigenina. Alterações de alguns parâmetros hematológicos da Channa punctatus foram acessados para determinar a influência destes compostos no peixe teste. Peixes foram expostos a concentrações sub-letais (80 por cento 0f LC50 em 24h) destes compostos por uma semana. Os peixes controles foram também expostos durante uma semana. A seguir, amostras de sangue foram obtidas do peixe controle e do experimental. O sangue foi estudado por parâmetros hematológicos selecionados (hematócrito, hemoglobina, contagem de células vermelhas e brancas, proteína plasmática total e concentração de glucose plasmática). Os índices hematológicos derivados da média da concentração corpuscular da hemoglobina (MCHC), a média de hemoglobina corpuscular (MCH) e a média de volume corpuscular (MCV), foram calculados. Concentrações sub-letais destes compostos causaram decréscimo dose-dependente dos valores da hemoglobina unidos a decréscimo de valores de hematócrito e das contagens de células sanguíneas vermelhas o que caracteriza indicação óbvia de anemia. As contagens totais de células brancas e a contagem diferencial destas células estavam diminuídas exceto pelos linfócitos que mostraram leve aumento. A proteína plasmática e a glicose estavam também baixas nos peixes expostos quando comparados com o controle. Os índices hematológicos MCH, MCHC, MCV estavam também diminuídos. Os resultados deste estudo revelam alto percentual de mortalidade e conseqüências deletérias à saúde de peixes submetidos à exposição aguda de Rutina, Talaxerol e Apigenina e portanto eles não devem ser usados diretamente em aquacultura sem conhecimento apropriado.
