Patent ID: 7709539

Claim:
A method for measuring antihyperglycemic efficacy of resveratrol comprising: a: dividing rats into groups including a first, normal (untreated) Sprague-Dawley (SD) group, and second and third groups; b: pre-treating the second group with insulin-dependent diabetes mellitus (IDDM); c: pre-treating the third group with insulin-independent diabetes mellitus (NIDDM); d: feeding the rats of each of the second and third groups pre-treated with IDDM and NIDDM with a dosage of resveratrol; e: observing antihyperglycemic efficacy in the rats of each of the second and third groups pre-treated with IDDM and NIDDM after being fed resveratrol for a period of time; and f: injecting the rats of the first group of normal SD with insulin every day for a period of time and, in addition, feeding some of the rats of the first group of normal SD with resveratrol, and comparing antihyperglycemic efficacy of the rats of the first group of normal SD fed with resveratrol with the rats of the first group of normal SD given only insulin; wherein the resveratrol is dissolved in homemade saline solution and is irrigated into the stomach of the rats, and wherein feeding the rats of each of the second and third groups pre-treated with IDDM and NIDDM comprises dividing the rats of each of the second and third groups into three subgroups and feeding dosages of 0.05, 0.1 and 0.5 mg per kg body weight to the rats of the three subgroups respectively of each of the second and third groups of rats pretreated with IDDM and NIDDM.
