(1) It′s action is similar to ouabain.

(2) Ouabain was added in order to induce oscillatory afterpotentials.

(3) Endogenous Ouabain is an endocrine hormone which playes an important role in the modulation of blood pressure, but the relationship between EO and H - PP remains unclear.

(4) Aim:To explore the effects of ouabain antibody on the blood pressure in renovascular hypertensive rats and the relationship between endogenous ouabain (EO) and the development of hypertension.

(5) Methods The antibodies to ouabain were prepared by immunizing rabbits. The optimum antisera titer and concentration of coating buffer with chessboard test and the assay were established.

(6) CONCLUSIONS: Ouabain has important role in controlling the growth and metabolism of vascular endothelial cell and vascular remodeling in the pathogenesis of hypertension.

(7) Bioactivity test on isolated rat heart failure model suggested 1 could increase coronary blood flow and myocardial con- tractive power compared with positive control ouabain.

(8) However, the effect of Berberine to prolong lethal time induced by Ouabain is less effective than Sodium Phenytoin, Quinidine and Propranolol.

(9) Objective: To study the antiarrhythmic activity of taurine-magnesium coordination compound (TMC) in vivo by using the arrhythmic model induced by ouabain of guinea pig.

(10) AIM : To compare the kinetics of positive inotropism between ibopamine ( Ibo ) and ouabain ( Oua ).

(11) The results indicated that petroleum ether extract had the ability to antagonize toxicity induced by ouabain, while water extract had little effect on it.

(12) Furthermore, XT not only attenuated the positive inotropic action, but also delayed the following toxicity response induced by ouabain in the isolated left atria.

(13) Conclusion THP had the effect of decreasing the amplitude of DAD of rabbit heart induced by ouabain thus reducing the chance of triggered ventricular arrhythmia induced by DAD.

(14) Conclution:The animal model of chronical digitalis intoxication can be constructed with continous injection ouabain intraperitoneally for two weeks.

(15) Objective To study the relationship between the concentration of serum endogenous ouabain (EO) and glomerular diseases.

(16) Positive inotropic effects and safety margin of milrinone had been compared with ouabain on ailing heart model in cats and guinea-pigs.

(17) Myofibrillar fragmentation, swelling of the cardiac myocytes, absence of the Z line, increases of the mitochondria and collagen fibers were found in ouabain group by transmission electron microscopy.

(18) Conclusion: Sample 1 and Sample 2 both resisted the occurrence of arrhythmias induced by aconitine, ouabain and ligation of coronary artery.
