| dc.description.abstract | Despite the several applications of modified cellulose, there is limited information on their safety, and antidyslipidemic functions, which are the focus of this study. To address this, cellulose isolated from Hibiscus sabdariffa cellulose was surface modified using nitrilotriacetic acid to produce nitrilotriacetic acid modified Hibiscus sabdariffa cellulose (HSNT). It was characterized using Fourier transformed infrared spectroscopy (FTIR), X-ray diffraction (XRD), thermogravimetric (TGA) analysis, scanning electron microscopy (SEM) and carbon, hydrogen, nitrogen, sulfur/oxygen (CHNS/O) analyzer. The study further investigated the safety of HSNT at the doses of 50, 100, and 150 mg kg−1 body weight in albino rats after a 7-day uninterrupted oral gavage. Histology of cardiac and hepatic tissues was observed, in addition to estimation of clinico-biochemical parameters such as atherogenic index of plasma (AIP), Castelli’s risk index (CRI-1), total cholesterol, high-density lipoprotein cholesterol (HDL-C), triglyceride (TG), albumin (ALB), aspartate aminotransferase (AST) and alanine aminotransferase (ALT). FTIR revealed peaks corresponding to the synthesis of HSNT, while XRD showed HSNT to have a crystallinity index of 53.20% with a type I cellulose crystal. HSNT had no significant effect on the absolute heart and liver weights, heart and liver organo-somatic indices, TG, AST, and ALB. Exposure to HSNT-50 caused a significant decrease in AIP levels. However, administration of HSNT-100 and 150 significantly reduced ALT, total cholesterol, and CRI-1 levels but caused a significant elevation in HDL-C levels. Cardiac histology revealed mild inflammatory and fatty infiltration of the myocardium, while the significant indications of the hepatic morphology included congestion of vessels and mild focal periportal infiltration at the HSNT-100 and HSNT-150 doses. Our preliminary data seem to indicate the potential of HSNT modification to resolve blood lipid abnormalities and make a case for an expanded study on its cardio-hepatic effects as well as study to understand the causes of congestion in hepatic vessels. | en_US |
