Nonspecific membrane effects of CH-103: hydrophobicity, surface activity and membrane fluidity studies in comparison with propranolol and practolol.
TLDR
The results suggest that the physicochemical properties of CH-103, similarly to those of propranolol, are the main determinants of its nonspecific membrane activity. Expand
Transesophageal pacemaker therapy in atrial flutter after procainamide pretreatment.
TLDR
Transesophageal atrial stimulation was applied in 56 patients to terminate atrial flutter and procainamide is more efficacious than digoxin (P < 0.05) in facilitating cardioversion by transesophagal stimulation. Expand
The effect of chronic diazepam treatment on hypoxia-induced alterations in functional activity of guinea pig myocardium.
TLDR
In atrial preparations obtained from guinea pigs treated with diazepam for 10 days, the hypoxia-induced depression of myocardial contractility was not altered, and results indicate thatdiazepam-treatment does not impaire the hypoxic tolerance ofMyocardium. Expand
Nonmutagenic activity of the nitroprusside.
TLDR
It is concluded that both pentacyanonitrosylferrate (II) and its adenine complex are nonmutagenic as for induction of chromosome breaks and point mutations. Expand
Long-lasting treatment with adenosine receptor antagonists: effects on hypoxic tolerance and vascular responsiveness.
TLDR
The vasoconstrictor effects observed after in vitro exposure of pulmonary arterial preparations to both noradrenaline and PGF2 alpha were similar, however, nitroglycerin and NO exerted more pronounced vasorelaxant effect than in specimens prepared from solvent-treated guinea pigs. Expand
Regulation of purinoceptors in guinea pig pulmonary artery: functional evidences.
TLDR
In isolated guinea pig pulmonary arteries, N6-cyclopentyladenosine exerted a concentration-dependent contraction, whereas 5'-N-ethylcarboxamidoadenosine (NECA), a non-selective A1/A2 receptor agonist, in the presence of DPCPX (a highly selective A1 receptor antagonist), produced a Concentration-related rapid relaxation.

[The effect of atherogenic diet on the entering of albumin into surviving segments of rabbit aortic wall].
TLDR
Authors have established that entering of albumin into the aortic wall of rabbits exposed to a cholesterin-rich diet in the early phase of atherosclerosis-in vitro-increases, but later on in the advanced phase of the disease decreases, which can be explained by the slow-down of the speed of diffusion into the vessel wall.
