Efficacy of choline and DHA supplements or enriched environment exposure during early adult obesity in mitigating its adverse impact through aging in rats

Hepato-protective potential of Choline and DHA supplements in rats exposed to tobacco particulate matter-A histological study

Introduction: Smokeless tobacco is known to induce liver damage by decreasing its detoxifying capability. Chronic exposure to tobacco particulate matter in various forms jeopardizes the normal function of vital organs including the liver. The tobacco rolled in tendu leaf; known as ‘bidi’ is an unfiltered cigarette having tobacco content that is different from those used in cigarettes and is referred to as 'bidi tobacco'. Bidi smoking or chronic exposure to bidi tobacco causes multi-organ diseases. Choline and docosahexaenoic acid (C & DHA) are dietary components known to have hepato-protective action. But the combined action of choline and DHA on tobacco particulate-induced liver damage is largely unknown. The present study was designed to assess the hepato-protective potential of choline and DHA supplements to rat dams and pups exposed to tobacco particulate matter. Liver histological changes were analyzed from groups of Wistar rat dams and their pups [Unexposed Normal controls (NC) and those exposed to different tobacco particulate matters namely, tendu leaf smoke, tobacco dust, and bidi smoke] with or without supplementation of both choline and DHA. Results: Hepatocytic morphological architecture showed non-alcoholic fatty changes in all rats exposed to tobacco particulate matter and more so visibly higher in tobacco dust exposed groups compared to the same in age-matched NC group. These changes were ameliorated in rats supplemented with choline & DHA and exposed to tobacco particulate matter. Conclusion: Chronic exposure of mothers and their offspring to tobacco particulates causes non-alcoholic fatty liver disease with microstructural changes. Dietary supplementation of choline and DHA to rats exposed to tobacco particulate matter provides hepato-protection and ameliorates the hepatocytic morphological changes.

Anti-aging and antioxidant of four traditional malaysian plants using simplex centroid mixture design approach

Aging is a naturally biological process with adverse effects. The continuous accumulation of reactive oxygen species (ROS) trigger cellular and tissue damage by activating several aging enzymes. The antioxidant properties of traditional medicinal plants used by Jakun aborigine's community are a promising approach to alleviate aging process and prevent Alzheimer. The aim of the current investigation was to optimize a novel anti-aging formulation from traditional plants (Cnestis palala stem, Urceola micrantha stem, Marantodes pumilum stem and Microporus xanthopus fruiting bodies) using simplex centroid mixture design (SCMD). After selecting the optimal formulations based on desirability function of antioxidant activity (DPPḢ, ABTS ˙ + and FRAP), they were further examined against the activity of aging-related-enzymes (collagenase, tyrosinase, acetyl- and butyrylcholinesterase). The single extracts of C. palala, U. micrantha and the binary mixture of C. palala and U. micrantha were the optimal formulations with high antioxidant activities. Single extract of U. micrantha showed the highest inhibition towards matrix metalloproteinase-1 (49.44 ± 4.11 %), while C. palala water extract showed highest inhibitions towards tyrosinase (14.06 ± 0.31%), acetylcholinesterase (32.92 ± 2.13%) and butyrylcholinesterase (34.89 ± 2.84%) enzymes. The single extracts of C. palala and U. micrantha displayed better activity as compared to the binary mixture formulation. In conclusion, these findings could be a baseline for further exploration of novel anti-aging agents from natural resources.
