CHAPTER ONE
INTRODUCTION
- Â BACKGROUND OF STUDY
The use of Ocimum gratissimum leaf extract to treat Alloxan induced diabetic rat and its oxidative and biochemical parameter assessments.
In Nigeria, especially in the southern part there is a consumption of plants extracts people consume. They also consume a lot of vegetable in their native diet and some of these plants are believed to cure some aliments. Ocimum gratissimum is one of the many found to lower glycaemia in Type-1 diabetes.
Many components of food such as secondary plants metabolites have been seen to alter biological processes which may reduce the risk of some chronic diseases in human such as diabetes.
Diabetes mellitus has its complications especially diabetes conditions among infected people, Ocimum gratissimum uses against various aliments has gained widespread acceptance in developing as well as developed nations (kolewale et al,. 2011). Diabetes mellitus is an important chronic metabolic disorder of public health concern, it occurs either as a result of pancreatic defects in insulin secretion or the failure of the effectively utilize secreted insulin or both. Hyperglycemia is a common consequence of uncontrolled diabetes, which may over time lead to serious damage to vascular tissue, heart, eye nerve and kidney.
Plants with known and suspected therapeutic potencies have been longed used in the alternative and complementary medicine. Numerous scientific reports exist, describing the relatively low toxicity and effectiveness in selected plants in management of diabetes.
Numerous scientific report exists, descending the relatively low toxicity and effectiveness of selected plants in the management of diabetes. It is unfortunate that a large number of those studies were conducted using either normoglycermeia or animal models.
Inducing of diabetes using either >100mg/kg body weight of Alloxan into these animal models, with recent review showing that Alloxan was one of the most frequently used diabetogenic agent globally.
High dose of the chemical are cytotoxic to the pancreatic beta cells giving rise to insulin deficiency.
- Â STATEMENT OF THE PROBLEM
The statement of the problem in this research work is that the efficacy of Ocimum gratissimum leaf extract through assaying of biochemical parameters of alloxan-induced diabetic rats.
VISION: To determine the effect Ocimum gratissimum methanol leaf extract has alloxan-induced diabetic rats through assaying of biochemical parameters.
ISSUE STATEMENT: Diabetes mellitus has become one of the prevailing health cases people face today, with no or little knowledge on how it can be controlled and managed, it could worsen beyond control and as far as oxidative damage is concerned, it would multiple the generation of free radicals.
METHODS: Apart from modern drugs that can be used to control and manage diabetes, the use of Ocimum gratissimum menthol leaf extract was employed in other to determine the effect on alloxan-induced diabetic rats through assaying of biochemical parameter.
1.3 AIMS AND OBJECTIVE
1.3.1 AIM OF THE STUDY
The aim of this study is to determine the effects of the methanol leaf extract of Ocimum gratissimum on the oxidative and biochemical parameter of alloxan –induced diabetic rats.
OBJECTIVES OF THE STUDY
Specifically, the study sort to:
- Determine the effects of the extract on MDA level
- Determine the effects of the extract on lipid profile
- Determine the effects of the extract on antioxidant enzyme activity.
