    ABSTRACT
    Diabetes a chronic (lifelong) disease marked by high levels of sugar in the blood. Diabetes is a common disease in older age, affecting about one in five individuals. In 2000, according to the World Health Organization, at least 171 million people worldwide suffer from diabetes, or 2.8% of the population. Its incidence is increasing rapidly, and it is estimated that by 2030, this number will almost double. Diabetes is also associated with mortality and significant morbidity, including neurological disability. Diabetes affects both peripheral nervous system and central nervous system. Neuropathy along with retinopathy and nephropathy appears in late stage of diabetes but effect on cognition starts in early stage of diabetes. Although the effects of diabetes on the peripheral nervous system are well established, the effects of diabetes on the central nervous system have been less clear. Several studies have found that diabetes is related to dementia and cognitive function. It is unclear in which stage of diabetes the cognitive decrements become manifest and how they progress over time. Study is conducted to confirm the association of cognitive function with diabetes.

    ABSTRACT
    The purpose of this research was to formulate and systemically evaluate in-vitro and in-vivo performances of mucoadhesive Ramipril microspheres for its potential use in the treatment of hypertension, myocardial infraction. Ramipril mucoadhesive microspheres, containing chitosan as mucoadhesive polymer and ethyl cellulose as carrier polymer, were prepared by an emulsion-solvent evaporation technique. Preformulation studies were carried out before formulation design. Total seven formulations were prepared.Microspheres were discrete, spherical, free-flowing and showed a good percentage of drug entrapment efficiency. An in-vitro wash off test showed that Ramipril mucoadhesive microspheres adhered more strongly to the gastric mucous layer and could be retained in the gastrointestinal tract for an extended period of time. In-vitro dissolution test was carried out by using phosphate buffer pH 6.8. All the formulations showed good dissolution profiles. Among all the formulation F5 showed good dissolution profile with 81.0% of drug release in 12 hours. In-vitro release kinetic data of Ramipril microspheres showed that the drug release mechanism was diffusion controlled as the plots of Higuichi model was linear. All formulations exhibited Non-Fickian diffusion (n value is in between 0.5 to 1) mechanism. Stability studies were done for the selected formulation indicates that there is no change in drug content of the formulation.The results showed a sustained anti-hypertensive effect over a longer period of time in case of mucoadhesive microspheres, compared to the powder. In conclusion, the prolonged gastrointestinal residence time and slow release of Ramipril resulting from the mucoadhesive microspheres, could contribute to the provision of a sustained anti-hypertensive effect.
