Influence of Hypoxia and Adrenaline Administration on Coronary Blood-Flow and Cardiac-Performance in Seawater Rainbow-Trout (Oncorhynchus-Mykiss)
(1994-08)
To investigate the relationship between cardiac performance and coronary perfusion, cardiovascular variables (Q, Vs, fH, PDA) and coronary blood flow (q(cor)) were measured in rainbow trout (Oncorhynchus mykiss) (1.2-1.6 ...
Oxygen transport in egg masses of the amphibians Rana sylvatica and Ambystoma maculatum: Convection, diffusion and oxygen production by algae
(1994)
Many amphibians lay their eggs in gelatinous masses up to 10-20 cm in diameter, posing problems for diffusive oxygen delivery. Oxygen may also be provided by water convection between eggs or by oxygen production by endogenous ...
Effect of Coronary Ablation and Adrenergic-Stimulation on In-Vivo Cardiac-Performance in Trout (Oncorhynchus-Mykiss)
(1994-01)
In fish, catecholamine-induced changes in cardiac performance in vivo are the result of complex interactions between the direct adrenergic effects on the heart and peripheral circulation and the reflex responses to increased ...
