Aminoguanidine inhibits the formation of advanced glycation end-products, and has been extensively examined in animals. However, administration of aminoguanidine decreases the hepatic content of pyridoxal phosphate. In order to avoid this problem, we developed an aminoguanidine pyridoxal Schiff base adduct and examined its efficacy in vitro as well as in a model of diabetic nephropathy. Mice wi...

In the present studies, the influence of inducible nitric oxide synthase (NOS) inhibition with aminoguanidine on renal function and blood pressure was examined in rats. Intravenous aminoguanidine infusion (60 mg x kg-1 x hr-1) for 40 minutes to anesthetized Sprague-Dawley rats (n=7) resulted in no significant changes in mean arterial pressure or renal cortical blood flow, while medullary blood ...

We sought to determine whether expression of the inducible, calcium-independent isoform of nitric oxide synthase (iNOS) contributes to the tissue damage produced by focal cerebral ischemia. The middle cerebral artery was occluded in halothane-anesthetized spontaneously hypertensive rats. Twenty-four hours later rats received intraperitoneal injections of the iNOS inhibitor aminoguanidine (100 m...

BACKGROUND AND OBJECTIVE The present study aimed to assess the effects of induced diabetes and the administration of aminoguanidine in the biomechanical retention of implants in rats. MATERIAL AND METHODS Thirty-six rats were randomly divided into six groups: group 1, healthy rats (no aminoguanidine); group 2 and group 3, healthy rats receiving 10 and 20 mg/kg of aminoguanidine daily, respect...

In the reaction of zinc(II) sulfate and chloride salt 2-acetylpyridine-aminoguanidine, two types complex were obtained, i.e., [Zn(H2O)6](H2L)2(SO4)3·3H2O [Zn(L)H2O(SO4)]·H2O, depending on presence LiOAc as deprotonating agent. The physicochemical, structural, photoluminescence properties complexes examined. first complex, obtained in absence LiOAc, Schiff base had role a counter-ion its doubly ...

Aging is associated with cardiac hypertrophy and arterial stiffening possibly associated with accumulation of advanced glycation end products (AGEs). We evaluated the effect of aminoguanidine, an inhibitor of AGE production, on end-stage alterations of renal and cardiovascular systems. Normotensive WAG/Rij rats were treated from 24 to 30 mo with aminoguanidine and compared with a control group....

Elevated production of nitric oxide (NO) by the inducible NO synthase (type II, iNOS) may contribute to the vascular hyporesponsiveness and hemodynamic alterations associated with sepsis. Selective inhibition of this isoenzyme is a possible therapeutic intervention to correct these pathophysiological alterations. Aminoguanidine has been shown to be a selective iNOS inhibitor and to correct the ...

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 with liquid paraffin and saline; grou...

Effects of aminoguanidine and aspirin on the development of retinopathy have been examined in 5-year studies of diabetic dogs. Either agent was administered daily in doses of 20-25 mg. kg(-1). day(-1). Because severity of hyperglycemia greatly influences development of the retinopathy, special effort was devoted to maintaining comparable glycemia in experimental and control groups. The retinal ...
