The influence of environmental P(O(2)) on hemoglobin oxygen saturation in developing zebrafish Danio rerio.
Several studies suggest that during early larval development of lower vertebrates convective blood flow is not essential to supply oxygen to the tissues, but information about the oxygenation status of larvae during the time of cutaneous respiration is still missing. If convective oxygen transport contributes to the oxygen supply to tissues, venous blood in the central circulatory system should...
متن کاملDanio Rerio, the Zebrafish
The zebrafish has long been a favourite model for the study of vertebrate development. Here we provide an overview of the current state of knowledge and resources for the study of this fish, with comments on the future direction of zebrafish genomics from Professor Mark Fishman and Dr Stephen Wilson.
متن کاملHemoglobin enhances oxygen uptake in larval zebrafish (Danio rerio) but only under conditions of extreme hypoxia.
The role of hemoglobin (Hb) in O(2) uptake by zebrafish larvae ranging in age from 5 to 42 days postfertilization was assessed under conditions of normoxia, moderate hypoxia and extreme hypoxia. This was achieved by exposing larvae with and without functional Hb to continuously declining oxygen levels (P(O(2))) in closed-system respirometers. Exposure to 5% CO for 2-4 h was used to render Hb ef...
متن کاملNitric oxide and vascular reactivity in developing zebrafish, Danio rerio.
We used a newly developed digital motion analysis video technique to study the effects of nitric oxide (NO) and epinephrine on the early larval arterial and venous vasculature of zebrafish. Application of the NO donor sodium nitroprusside resulted in a significant increase in both the venous and arterial vessel diameters, whereas N(G)-nitro-L-arginine methyl ester caused a significant decrease ...
متن کاملBIOLOGY OF ZEBRAFISH, Danio rerio
Zebrafish, Danio rerio (Hamilton), is one of the most important vertebrate model organism in genetics, developmental biology, neurophysiology and biomedicine (Rubinstein, 2003; Amsterdam and Hopkins, 2006). It is a small, robust fish, so large numbers can be kept easily and cheaply in the laboratory, where it breeds all year round. Development is rapid, with precursors to all major organs devel...
