Hematology and plasma biochemistry in rats fed with diets enriched with fatty fishes from Amazon region

Abstract

OBJECTIVE: Rats fed diets enriched with fatty fish from the Amazon region had Hematology and plasma biochemistry analyzed. METHODS: Forty Wistar rats were divided into four groups: control group fed a standard diet; mapará group fed a diet enriched with Hypophthalmus edentatus; matrinxã group fed a diet enriched with Brycon spp.; and tambaqui group fed a diet enriched with Colossoma macropomum. After thirty days the rats had an red blood count and plasma biochemistry. RESULTS: Hematocrit and hemoglobin levels were higher in rats fed tambaqui and matrinxã than in those fed the standard diet of mapará. However, mapará increased cholesterol, especially low-density lipoprotein cholesterol and high-density lipoprotein cholesterol. All fish-enriched diets reduced triacylglycerols. CONCLUSION: Diets enriched with fatty fish from the Amazon region reduce triacylglycerol and increase high-density lipoprotein cholesterol, especially the diet enriched with tambaqui. Tambaqui and matrinxã affected hematocrit and hemoglobin levels, but not mapará. Further research is needed to determine the benefits of diets enriched with fatty fish from the Amazon region.

Loganic Acid, an Iridoid Glycoside Extracted from Cornus mas L. Fruits, Reduces of Carbonyl/Oxidative Stress Biomarkers in Plasma and Restores Antioxidant Balance in Leukocytes of Rats with Streptozotocin-Induced Diabetes Mellitus

“…RBCs count was carried out manually using a counting chamber. Hemoglobin concentrations in whole blood were measured using the cyanmethemoglobin method and mean cell hemoglobin (MCH) was determined according to Souza et al [ 16 ]. Evaluation of level of glycated hemoglobin (HbA1 c ) was based upon the generation of 5-hydroxymethylfurfural (5-HMF) from ketoamine after treatment with oxalic acid and its subsequent reaction with thiobarbituric acid (TBA) to form a coloured adduct.…”

Antidiabetic and Antioxidative Potential of the Blue Congo Variety of Purple Potato Extract in Streptozotocin-Induced Diabetic Rats

“…The content of glycated hemoglobin (HbA1c) in blood was measured following the method described by Vitak et al [62], based on the generation of 5-hydroxymethylfurfural from ketoamine after treatment with oxalic acid and its subsequent reaction with thiobarbituric acid to form a colored adduct. Hemoglobin concentrations in the whole blood were determined using the cyanmethemoglobin method, whereas mean cell hemoglobin (MCH) was determined according to Souza et al [63]. The total number of erythrocytes and leukocytes in blood was calculated manually using a counting chamber.…”
