Diabetes in humans and in experimental animals produces changes in the function and structure of the small intestine. The authors determined the activity of intestinal disaccharidases (maltase and sucrase) and of 6-phosphofructo-1-kinase (PFK-1) in enterocytes isolated from the small intestine of male Wistar rats (2.5 to 3 months old) with experimental nonobese type 2 diabetes, induced by strep...

Dyslipidemia is one of the most common complications in diabetes mellitus, which increases risk of premature atherosclerosis. Drugs having antihyperlipidemic activity in addition to their hypoglycemic effect in diabetes may be suitable anti-atherosclerotic agents in diabetic patients. The present study was aimed to investigate the anti-atherosclerotic activity of an aqueous extract of Withania ...

This study aimed to investigate the potency of silymarin (SMN) and melatonin (MEL) on restoring the pancreatic  cells in streptozotocin (STZ)-induced diabetic rats. Male Wistar rats were divided into five groups, including: control (C), untreated diabetic (D), SMN-treated diabetic (50 mg/kg, orally), MEL-treated diabetic (10 mg/kg, i.p.), and SMN plus MEL-treated diabetic rats. Diabetes was in...

The present study investigated the effects of Vernonia cinerea (VC) on the reproductive function in streptozotocin (STZ)-induced diabetic male rats. Six-week-old male Sprague-Dawley rats were randomly divided into four groups: group 1, normal control rats; group 2, diabetic untreated rats; group 3, diabetic rats treated with VC (10 mg/kg); and group 4, diabetic rats treated with VC (40 mg/kg). ...

Lespedeza has been used for the management of diabetes in folklore medicine. The purpose of this study is to investigate the protective effects of the methanol extract of Lespedeza davurica (LD) on cytokine-induced β-cell damage and streptozotocin- (STZ-) induced diabetes. RINm5F cells were treated with interleukin- (IL-) 1β and interferon- (IFN-) γ to induce pancreatic β-cell damage. The expos...

The aim of the present study was to evaluate antihyperglycemic activity of methanol extract of Citrus maxima leaf (MECM) in streptozotocin (STZ; 65 mg/kg b.w.) induced diabetic rats. Three days after STZ induction, diabetic rats received MECM orally at a dose of 200 and 400 mg kg-1 body weight daily for 15 days. Glibenclamide (0.5 mg kg-1 p.o.) was used as a reference drug. Blood glucose levels...

OBJECTIVES Diabetic nephropathy is an important long-term complication of diabetes mellitus which appears to be partially mediated by an increase in secretion of transforming growth factor-β (TGF-β). Fibromodulin, the small leucine-rich proteoglycan, has been proposed to be the potent TGFβ1 modulator. In this study, the therapeutic effects of recombinant adenoviral vectors expressing fibromodul...

In the present study, the anti-diabetic effect of aqueous extract of Sida rhombifolia ssp. retusa (Malvaceae) leaves was studied in normal and streptozotocin (STZ)-induced (60 mg/kg, single intraperitoneal injection) diabetic rats. Hypoglycemic activity in normal rats was tested after administration of 200 mg/kg of extract. Aqueous extract showed a 15% reduction in plasma glucose level after 1....

It has been known that acupuncture has various effects such as analgesia, promotion of homeostasis, improvements in brain circulation, and rectification of internal disorders. Neuropeptide Y (NPY), a 36-amino-acid peptide, is known to increase appetite. In the present study, the effect of acupuncture stimulation at Zusanli (St.36) on NPY expression in the Streptozotocin (STZ)-induced diabetic r...

OBJECTIVE The present study was hypothesized to investigate the beneficial effects of fresh, aged, and cooked garlic extracts on blood glucose and memory of diabetic rats induced by streptozocine (STZ). MATERIAL AND METHODS Diabetes was induced by an intraperitoneal injection of STZ (60 mg/kg body weight). An oral dose of 1000 mg/kg of each garlic extract was given daily for 4 weeks after dia...
