ABSTRACT

This inquiry aims to assess whether or not a methanol extract of Momordica charantia is able to normalise lipid and starch-sugar levels in diabetic rats f a high-fat and a low-carbohydrate diet. Different doses of the extract are administered orally for 45 days. The rats are bl at the beginning of the experiment and at 15-day intervals. family glucose, triglyceride, low-density lipoprotein (LDL) high-density lipoprotein (HDL) and cholesterol are estimated. originates showed that M. charantia extract normalised offspring glucose level, reduced triglyceride and LDL flushs and increased HDL level. The animals repeled to a diabetic state one time the M. charantia extract was discontinued.

Introduction

Diabetes mellitus is a disease associated with disorders of carbohydrate metabolism whereby diabetic sugar transport to cells is limited by way of reduced insulin production or on insulin resistance caused by, for example, obesity or inherited factors. It is a major risk factor for shock heart disease and other family vessel diseases, and studies have reported that hypertriglyceridaemia and hypercholesterolaemia are public in diabetic subjects who bring to maturity such conditions. High levels of circulating lipid is to be paid to an increased turnover of fatty acid, as as it was molecules are used to generate intensity via B-oxidation.1

People with diabetes mellitus may avoid or delay the attack of these diseases by reducing lipid stres according to controlling risk factors such as weight and diet. Diet hinder involves reducing the fat ease of the diet and supplementing it with fruits and vegetables.

Momordica charantia is a fruit commonly used in the Indian community across the African continent and also in India. In the Ayurvedic body of medicine, M. charantia is used in the treatment of inflammation, skin disease and diabetes, and a hypoglycaemic event has been reported by many authors.2-5 It also increases grape-sugar level in hypoglycaemic rats as a be derived of its thyrogenic effect,3 and polypeptide P in the extract is reported to have a hypoglycaemic property6

Lipids are important macromolecules for the maintenance of lonely dwelling structure and function. A carbohydrate-rich diet increases descendants sugar level and a fat-rich diet may culminate in ketosis in diabetics; therefore, diet supplementation in this form into groups should aim to address these problems

M charantia extract has a significant clearing event on circulating glucose, low-density lipoprotein (LDL) and triglycerides in diabetic rats maintained onward a normal diet.7 Therefore, the not absent study aims to assess whether or not M charantia extract shows the same results in diabetic rats f a diet high in fat and reasonable in carbohydrate.

Materials and methods

M charantia was obtained from local farmers and its authenticity was confirmed with the Herbarium section of the Department of Botany, University of Nairobi. The fruit was dried, crushed to a pulverize and extracted in 70% methanol and distilled in subordination to reduced pressure in a Buchi-type rotary evaporator. The concentrated extract was kept in a vacuum desiccator. The yield was 5% (w/w) of the total dried weight of the fruit.

Male albino rats (Horts Men strain), 200-250 g in weight, were used in all experiments and were kept in standard laboratory conditions. Diabetes was induced by means of injecting them with alloxan monohydrate, (60 mg/kg carcass weight) on two consecutive days. The animals had liberated access to water and nutriment Two types of feed were used during the experiment. The respect group was fed a normal diet and the diabetic rats were given a special diet containing 45% fat (90% saturated) and 30% carbohydrate. This is different from the usual prescribed diet for diabetics, which is 45% carbohydrate and 30% fat.

Kits for starch-sugar triglyceride, cholesterol, LDL and high-density lipoprotein (HDL) were used (Human Gesellschaft, Germany), and the manufacturer's guidelines were followed. Alloxan monohydrate was obtained from Sigma.

Twenty-five rats were used for the experiment, divided equally into five trial form into groupss comprising the reference group (A), diabetic command group (DC) and three diabetic experimental clusters (DE1, DE2 and DE3). Rats in the three DE clusters were given different doses of the extract (80 100 and 120 mg/kg visible form [i]or[/i] frame weight), while rats in the other couple groups were given distilled water.

All the rats were bl upon the day before the start of the experiment and in succession day 15, day 30 and day 45 of the experiment. Thereafter, all rats were turn backed to a normal diet. Rats in form into groups DE3 were observed for a further 30 days and bl upon day 60 and day 75 for assessment of diabetic sugar triglyceride, cholesterol, LDL and HDL levels

A tail-tip bleeding rule was used in all the cases and serum was infered and stored in a freezer outcomes were expressed as mean ?± SE Student's t ordeal was used for statistical comparisons.

Results

Glucose

Blood grape-sugar level showed a dose-dependent reply to the M. charantia extract. The 80 mg/kg dose failed to effect a statistically significant reduction unless the 100 and 120 mg/kg doses reduc starch-sugar level to normal by day 15 (9145 ?± 623 mg/100 mL) and matched the flushs in the reference group. This flat stayed within the normal range up to day 45 In contrast, diabetic command rats fed the high-fat diet if it were not that not the M. charantia extract showed a gradual increase in grape-sugar level (73.34 ?± 7.60 mg/100 mL onward day 0 and 299.64 ?± 963 mg/100 mL forward day 45). On return to a normal diet, grape-sugar levels in group DE3 increased significantly on day 75 (P
