title: Experimental model proposed to deduce pharmacological evidence of the beta-cell neogenesis activity of Argyrolobium roseum vis-a-vis an evaluation of its hypoglycemic activity.
abstract: BACKGROUND
  Argyrolobium roseum is described in texts for its botanical aspects with no mention of its therapeutic uses. Recently, a solvent fraction of this plant has been reported to possess insulin secretagogue activity.
  
  
  OBJECTIVE
  Primary objective of the study was to evaluate the hypoglycemic activity of different fractions of Argyrolobium roseum plant. Secondary objective was to devise a model for detecting its beta-cell neogenesis activity.
  
  
  METHODS
  Alcoholic fraction (AR) was studied in fasting, glucose-loaded and streptozotocin (STZ)-treated hyperglycemic rats. For deducing beta-cell neogenesis activity, a sub-lethal dose of STZ, causing delayed death in the animals, was administered.
  
  
  RESULTS
  AR in a dose of 200 mg/kg showed hypoglycemic activity in fasting and STZ-treated rats. With sub-lethal dose of STZ, recovery from hyperglycemia was seen.
  
  
  CONCLUSIONS
  AR of Argyrolobium roseum possesses hypoglycemic and a possible beta-cell neogenesis activity. Further studies are required to confirm its beta-cell neogenesis potential by cytological methods and to establish its role in the treatment of type 2 diabetes.
