... physiological strategies for surviving in the cold, a cold-dormant crucian carp ( Carassius carassius L.) and a cold-active rainbow trout ( Oncorhynchus mykiss ), were used in acclimation experiments. The I Na of carp and trout were also compared with I Na of a cold stenothermal burbot( Lota lota...

...Jørund Sollid; Paula De Angelis; Kristian Gundersen; Göran E. Nilsson SUMMARY We show that crucian carp ( Carassius carassius ) living in normoxic(aerated) water have gills that lack protruding lamellae, the primary site of O 2 uptake in fish. Such an unusual trait leads to a very small...

... pulse in voltage-clamped heart cells, we examined sarcolemmal Ca 2+ influx through Na + /Ca 2+ exchange and L-type Ca 2+ channels in crucian carp ( Carassius carassius L.) ventricular myocytes. When other cation conductances were blocked, a Ni 2+ -sensitive current with the characteristic voltage...

...Matti Vornanen ABSTRACT A patch-clamp analysis of L-type Ca 2+ current in ventricular myocytes of cold- and warm-acclimated rainbow trout ( Oncorhynchus mykiss ) and crucian carp ( Carassius carassius ) hearts was performed. Trout were acclimated at 4 and 17°C and carp at 4 and 24°C for a minimum...

...Dan Johansson; Göran E. Nilsson ABSTRACT The crucian carp ( Carassius carassius L.) is one of the most anoxia-tolerant vertebrates known, being able to maintain ion homeostasis in its brain for many hours of anoxia. This study aims to clarify the importance of glycolysis during anoxia and also...

...Dan Johansson; Göran E. Nilsson; Erik Törnblom ABSTRACT Crucian carp ( Carassius carassius L.) is an exceptionally anoxia-tolerant vertebrate. To determine whether isolated crucian carp brain tissue survives anoxia and whether it displays anoxic metabolic depression, heat production (using...

...Göran E. Nilsson; Peter Rosén; Dan Johansson ABSTRACT The crucian carp ( Carassius carassius L.) is one of the most anoxia-tolerant fishes. An important strategy used by the crucian carp to survive anoxia is to lower its rate of energy consumption. Anoxia-tolerant fish are known to utilize...

...Nina Matikainen; Matti Vornanen ABSTRACT The temperature dependence of heart rate and isometric contractile properties of cardiac tissue was determined in thermally acclimated crucian carp (Carassius carassius L.). Fish were adapted for more than 3 weeks to 5 and 15°C during both summer and winter...

... depression, crucian carp (Carassius carassius L.) were given an inhibitor of GABA synthesis, isoniazid, and the rate of anoxic ethanol production (ethanol being the main end product of energy metabolism in anoxic crucian carp) as well as the rates of normoxic and hypoxic oxygen consumption were measured...

...G. E. Nilsson ABSTRACT Crucian carp ( Carassius carassius L.), which are extremely anoxia-tolerant, were exposed to 17 days of anoxia at 8 °C. One group of fish was transferred to normoxic water for 1–8 h immediately after the anoxic period. All the eight amino acids measured in brain (including...

...E. Nilsson Göran ABSTRACT In the brain, oxygen is required for both the synthesis and the degradation of monoamine transmitters, so monoaminergic systems can be expected to be strongly affected by anoxia. However, crucian carp ( Carassius carassius L.) may survive anoxia for many days or even weeks...
