4 The prevalence of diabetes of all age groups
worldwide is projected to rise from 171 million in 2000 to 366 million in 2030.5 Reason of this rise includes increase in sedentary life style, consumption of energy rich diet, obesity, higher life span, etc.6 DM is a major and growing health problem in most countries. It causes considerable amount of disability, premature mortality, and loss of productivity as well as increased demands on health care facilities. As diabetes aggravates and β-cell function deteriorates, the insulin level begins to fall below the body’s requirements and causes prolonged and Fulvestrant more severe hyperglycemia.7 Hyperglycemia induces long term complications of diabetes such as cardiovascular complications and micro vascular complications such as retinopathy, nephropathy and neuropathy and foot ulcer.8 Based on the WHO recommendations hypoglycemic agents of plant origin used in traditional medicine are important.9 The attributed antihyperglycemic effects of these plants is due to their ability to restore the function of pancreatic tissues by causing an increase in insulin output or inhibit the intestinal absorption of glucose or to the facilitation of metabolites in insulin dependent Doxorubicin mouse processes. Hence treatment with herbal drugs has an effect on protecting
β-cells and smoothing out fluctuation in glucose levels. Most of these plants have been found to contain substances like glycosides, alkaloids, terpenoids, flavonoids etc. that are frequently implicated as having antidiabetic effects.10 Alloxan was one of the most widely used chemical diabetogen during initial research work on experimental diabetes. It is a cyclic Unoprostone urea analogue of chemical composition 2,4,5,6-tetraoxo-hexa hydropyrimidine.11 Alloxan induces diabetes in animals and impairs glucose induced insulin secretion from b cells of Islets of Langerhans of Pancreas. It has been reported that alloxan rapidly and selectively accumulates in β-cells in comparison with non-b cells. Several reports directly or indirectly indicate that alloxan
affects the membrane potential and ion channels in β-cells.12 Syzygium cumini also called Eugenia jambolana (EJ) has been reported to have hypoglycemic effects both in experimental models and clinical studies. S. cumini seed apart from hypoglycemic activity has been reported to have anti-inflammatory, 13 neuro psychopharmacological, antibacterial, 14anti-oxidant 15 and ant diarrhoeal effects. 16 In the present investigation, aqueous extract of seeds of S. cumini was used to evaluate the antidiabetic activity and liver protective effect in alloxan induced diabetic Swiss albino mice. Healthy Swiss albino mice of both sexes, weighing approximately (28–32 g) were used in the pharmacological studies.
