ABSTRACT

BACKGROUND: Physiological values reflect the health condition and responses of individuals to handling in captivity. The aim of this study was to establish hematological and serum biochemistry parameters of clinically healthy animals of the Alouatta guariba clamitans subspecies. METHODS: We collected blood samples from adult males and females kept at the Center for Biological Research of Indaial after chemical containment with 3.9 mg/kg of tiletamine hydrochloride and zolazepam. RESULTS: Significant differences between males and females were found in the levels of erythrocytes, hemoglobin, hematocrit, lymphocytes, neutrophils, platelets, mean corpuscular hemoglobin concentration (MCHC), and gamma-glutamyltranspeptidase (GGT). CONCLUSIONS: Our results suggest the existence of sexual dimorphism in some physiological parameters of A guariba clamitans. The parameters reported herein can be used as reference values for other populations kept under similar conditions.

ABSTRACT

CONTEXT: Cardiovascular disease is the leading cause of death worldwide and the consumption of red cabbage (Brassica oleracea var. capitata f. rubra DC. - Brassicaceae) has been linked with the reduction risk of chronic diseases. OBJECTIVE: The present study assesses the bioactive metabolites and hypolipidemic effect of red cabbage on rats. MATERIALS AND METHODS: The content of total phenols, flavonoids, anthocyanins, carotenoids, ascorbic acid and antioxidant capacity were assessed, while individual phenolic acids and flavonoids were detected using reverse phase-high performance liquid chromatography (HPLC) analysis. Acute hypolipidemic activity of aqueous extract of red cabbage (RC - 125, 250 and 500 mg/kg) was investigated using a Triton WR-1339 (400 mg/kg) induced hyperlipidemic Wistar rats compared to fenofibrate (65 mg/kg). RESULTS: The HPLC analysis of extracts revealed eight phenolic acids, gallic, protocatechuic, p-hydroxybenzoic, m-coumaric, syringic, caffeic, cinnamic, dicaffeoylquinic and three flavonoids, epicatechin, epigallocatechin, gallocatechin. Furthermore, the aqueous extract showed higher amounts of total phenolics (116.00 mg/g), flavonoids (161.32 µg/g) and, antioxidant activity (87.19%) than the hydromethanolic (89.33 mg/g, 123.34 µg/g and 75.07%), respectively. The RC significantly (p < 0.001) ameliorated the levels of cholesterol, triglycerides and lipoproteins alterations in hyperlipidemic rats without toxicity. DISCUSSION AND CONCLUSION: Herein, the RC presented the higher amounts of phenolics and flavonoids comparing with the hydromethanolic extract. Additionally, the RC showed as the majority compounds, dicaffeoylquinic and cinnamic acids, and the flavonoids epicatechin and gallocatechin. Furthermore, the RC demonstrated a beneficial effect against hypercholesterolemia and hypertriglyceridemia, demonstrating its potential therapeutic effect on these risk factors of cardiovascular diseases.
