Investigating the antioxidant effects of Aloe vera: Possible role in regulating lipid profile and liver function in high fat and fructose diet (HFFD) fed mice.

Fat rich diets are believed to induce obesity and contributes to the development of diabetes and cardiovascular disease while high fructose diet was reported to increase gut surface area and enhance nutrient uptake resulting in weight gain. The study investigate the role of Aloe vera supplementation on lipid profiles, oxidative stress as well as liver and hear histology in high fat and fructose diet fed mice. Twenty mice were distributed into four groups (n=5). The groups received regular diet, high fat and fructose died (HFFD), HFFD plus 10% Aloe vera (HFFD+AV1) and HFFD plus 20% Aloe vera (HFFD+AV2) respectively for 10 weeks. The cholesterol level of HFFD+AV treated mice were significantly lower compared to HFFD treated mice. The ALT level was significantly increased in HFFD treated mice relative to the control. Aloe vera significantly improve albumin level as well as Catalase and superoxide dismutase activities of HFFD treated mice. The liver tissues of control and HFFD+AV2 treated mice showed normal hepatocytes. The study suggest that Aloe vera supplementation could protect against HFFD induced oxidative stress and hyperlipidemia. These findings might be used for further research on food supplementation for the control of metabolic disorders.

Effects of Malaysian strains of Toxoplasma gondii on behaviours and their possible risk in schizophrenia-like rat model

Toxoplasma gondii (T. gondii) is a protozoan parasite that reside majorly in the brain of its intermediate host. T. gondii infected rodents shows some degree of behaviour deficits, while T. gondii infection in humans is associated with psychiatric problems such as schizophrenia. The present study aimed to evaluate the effects of Malaysian strains of T. gondii on rats. Forty five, four weeks old, male Wistar rats were used. The rats were assigned into five groups: two control groups (CG1 and CG2) and three experimental groups (EG1, EG2, EG3). CG1 rats received phosphate buffered saline (PBS), CG2 received MK-801 (as a model for schizophrenia), EG1, EG2, EG3 received orally 5 x 103 single T. gondii oocysts strain of type I, type II and type III respectively. After infection, all the five groups of rats were tested for T. gondii antibodies at two weeks post-infection (PI). Behavioural tests of exploratory activity (open field) and spatial learning and memory retention (Morris water maze) were performed on the ninth and tenth weeks PI followed by histological staining of rat brain. T. gondii IgM antibodies were detected in EG1, EG2 and EG3, but not in CG1 and CG2. The behaviour results demonstrated that rats from CG2, EG1, EG2 and EG3 had increased in their locomotor activities and memory deficits compared to control, while learning remain intact. Moreover, tissue cysts were found widely distributed exclusively in the whole brain of EG1, EG2 and EG3 without tropism. These findings taken together, implies that Malaysian strains of T. gondii are implicated in some causes of behaviour changes that are responsible for schizophrenia-like conditions if humans were infected.
