Effects of Various Propolis Concentrations on Biochemical and Hematological Parameters of Rainbow Trout (Oncorhynchus mykiss)
Ecotoxicology and Environmental Safety, Volume 72, Issue 7, October 2009, Pages 1994-1998
Biochemical and hematological parameters in blood of rainbow trout treated to various concentrations of propolis for 96 h were determined.
Total leukocyte count and granulocytes values increased in 0.02 and 0.03 g/L propolis groups. There was a decrease in agranulocytes erythrocytes, hemoglobin and hematocrit values for fish exposed to 0.02 and 0.03 g/L propolis. MCV and MCH values were significantly increased; 0.02 and 0.03 g/L propolis caused an increase in the levels of glucose, blood urea nitrogen, triglyceride, total cholesterol, lactate dehydrogenase, amylase and gamma glutamyltransferase. There was a decrease in the levels of aspartate aminotransferase and alkaline phosphatase. Hematological and biochemical protective effects of 0.01 g/L propolis were investigated.
Dose-dependent effects of propolis on blood of fish can be favorable, opening new perspectives of investigation on their biological properties and utilization.
