Potential of Ascorbic Acid Supplements to Ameliorate the Deleterious Effects of Hyperuricemia on Albino Wistar Rats' Hippocampus (Structural and Functional Study).

INTRODUCTION: Diet rich in purines may increase the serum level of uric acid causing hyperuricemia, contributing to learning and memory to impairments. Ascorbic acid has a potent antioxidant potential. The hippocampus is a pivotal component of human brains and other vertebrates that plays crucial roles in the consolidation of information and spatial memory. Our study was mainly designated to examine the potential palliative role of ascorbic acid supplements on harmful effects induced hyperuricemia on the hippocampus of albino Wistar rats. METHODS: Forty rats were subgrouped into the control group, ascorbate-only group, hyperuricemic group, and combined hyperuricemia and ascorbate group. RESULTS: Ascorbic acid has strongly preserved the histological architecture and maintained the normal hippocampal functions in the hyperuricemic group. CONCLUSION: The anti-inflammatory and antioxidant properties of ascorbic acid could protect the hippocampus of albino Wistar rats against the hazardous impact of hyperuricemia.

Potential effect of fish oil to preserve expression of cell cycle and tight junction regulating genes in colon after di-isononyl phthalate ingestion in albino Wistar rats.

Di-isononyl phthalate (DIP) is considered a high molecular-weight subtype of phthalates that are commonly used and could easily affect the gastrointestinal tract (GIT). Eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) are the main active components of fish oil (FO), and their anti-inflammatory potential was previously documented. The current study was designed to investigate the protective potential of fish oil against the impacts of DIP exposure on the colon of albino Wistar rats. Sixty albino Wistar rats were divided into Control group received corn oil for ten days. Di-isononyl phthalate treated group received DIP. Di-isononyl phthalate + fish oil treated group received both DIP and FO. FO was found to preserve the histological architecture, tight junction and cell cycle of the colon. In conclusion, the current study provided an evidence that FO has a protective potential against DIP further examinations to be done to fully understand the molecular basis of this potential as a step for further clinical applications.
