Effect of nitric oxide synthase inhibitor on allergen- and hyperventilation-induced bronchoconstriction in guinea-pigs.
To elucidate the role of endogenous nitric oxide (NO) in allergen- (AIB) and hyperventilation-induced bronchoconstriction (HIB), the effects of an NO synthase inhibitor, NG-nitro-L-arginine methyl ester (L-NAME), on AIB and HIB were studied in guinea-pigs. In the AIB group, 21 anaesthetized guinea-pigs, actively sensitized with 1% ovalbumin, were challenged with aerosolized 0.1% ovalbumin solut...
متن کاملStudy of chronic effect of Losartan in inhibition of kidney glomerular number and glomerular volume changes in uninephrectomized diabetic rats(Stereological study).
Background: Diabetic nephropathy is one of the cause of the end stage of renal disease (ESRD). Hyperglicemia activate intrarenal Renin-Angiotensin system and highly AngiotensinII is produced locally in glomeruli. In this research AT1(Angiotensin type 1) receptors blocked by Losartan and effects of this drug in inhibition of renal structural lesions were assessed quantitatively. Materials & me...
متن کاملEffects of a standard hyperbaric oxygen treatment protocol on pulmonary function.
The prescription of hyperbaric oxygen (HBO) therapy for disorders not related to diving is increasing. Pulmonary oxygen toxicity is well known, but the effect of the cumulative oxygen exposure corresponding to a standard HBO treatment protocol has not been quantified before. Twenty patients (10 male) had 21 HBO treatments at a partial pressure of oxygen of 240 kPa for 90 min daily. None had any...
متن کاملVEGF and bFGF stimulate myocardial vascularization in embryonic chick.
We tested the hypothesis that early vascularization of the embryonic heart is enhanced after bolus injections of vascular endothelial growth factor (VEGF) and basic fibroblast growth factor (bFGF) into the vitelline vein before the onset of myocardial vasculogenesis (3.5 days, stage 21). Electron and light microscopy were utilized to obtain morphometric data. At stages 29 and 31, myocardial ves...
متن کاملPhysiological plasma levels of androgens reduce bone loss in the ovariectomized rat.
The effect of androstenedione (ADIONE) slow-release pellets on cancellous bone volume (BV/TV) at the tibial metaphysis was investigated in ovariectomized (OVX) rats at various times from 21 to 180 days. Plasma levels of ADIONE and testosterone (T) in OVX rats were significantly reduced at 21 days and were restored close to levels in the sham rats with the 1.5-mg ADIONE pellet. OVX animals with ...
