This study was conducted to investigate the effect of curcumin, obtained from Curcuma longa, in comparison with rosiglitazone on the progression of insulin resistance and type 2 diabetes mellitus (T2DM) and the mechanisms underlying this effect. Insulin resistance and T2DM was induced in male Sprague Dawley rats by high fat diet (HFD) feeding for 60 and for(More)
Abomasal ulceration occurs commonly in suckling calves, and the cause for the high prevalence of abomasal ulceration is unknown. We hypothesized that diet may play a role in the etiopathogenesis of abomasal ulceration. Six male dairy calves with an abomasal body cannula suckled fresh Holstein cow's milk, all milk-protein milk replacer, or combined milk- and(More)
Poly(ADP-ribose) polymerase (PARP) enzyme contributes to nephropathy, a serious diabetic complication which may lead to end-stage renal disease. The study aims to investigate the effect of PARP over-activation on kidney functions in a type 2 diabetic rat model. The study also tests the therapeutic use of PARP inhibitors in diabetic nephropathy. Type 2(More)
Cardiovascular complications are the major causes of mortality among diabetic population. Poly(ADP-ribose) polymerase-1 enzyme (PARP-1) is activated by oxidative stress leading to cellular damage. We investigated the implication of PARP-1 in diabetic cardiac complications. Type 2 diabetes was induced in rats by high fructose-high fat diet and low(More)
This study examined the possible hepatoprotective effect of aminoguanidine in comparison with silymarin and investigated the possible beneficial effects of the combination of aminoguanidine and silymarin on CCL4-induced liver fibrosis. Male Wister albino rats were randomly divided into five groups (10 rats/group). Group I included control rats injected only(More)

BACKGROUND/AIM Portal hypertension is an important and potentially fatal complication of liver disease whereby cellular and fibrotic alterations manifest to increase portal venous pressure. The aim of this study is to investigate the effect of captopril, pentoxifylline (PTX), and cordyceps sinensis in pre-hepatic portal hypertensive rats. SETTINGS AND(More)
OBJECTIVE To determine the effects of 3 commercially available, orally administered electrolyte solutions (OAEs) on abomasal luminal pH and emptying rate in dairy calves, compared with the effect of orally administered milk replacer. DESIGN Randomized crossover study. ANIMALS 6 male dairy calves (age, 12 to 31 days). PROCEDURES Calves were surgically(More)
The present study aimed to investigate the antidiabetic effects of Cordyceps sinensis, taurine and their combination in comparison with glibenclamide both in vivo and in vitro using streptozotocin rat model. The diabetic rats were orally given glibenclamide, C. sinensis, taurine or Cordyceps and taurine combination for 21 days. Their effects were studied(More)
