..., and the allometric dependency for RBC loss in HLU and control animals shared a common power (−0.054±0.008) but a different Y 0 coefficient (8.66±0.40 and 10.73±0.49, respectively, P <0.05). Blood volume in HLU animals was unchanged compared with that of controls, disregarding body size. The allometric dependency...

... measured blood flows and pressures in anaesthetized Python regius . The anaesthetized snakes exhibited the archetypal tachycardia as well as a rise in both venous pressure and MCFP that fully account for the approximate doubling of stroke volume. There was no rise in blood volume and the elevated MCFP must...

.... Nutritionally stressed sea lions lost both lipid and lean mass, resulting in potentially lower muscle O 2 stores. However, total body O 2 stores increased due to rises in blood O 2 stores associated with having higher blood volumes. Nutritionally stressed sea lions also had higher mass-specific metabolic rates...

... ). The latter reamed through the bottom ice and then used the channel as a breathing hole. At the end of January 2001, muscle biopsies (eight birds) and blood volume determinations (five birds) were conducted under general isoflurane anesthesia. The birds were later released after helicopter transport...

...) caused a progressive fall in Hct to ∼12% at day 15. Hct decline was strictly proportional to the extent of blood withdrawal. Incremental Ringer solution injection over an 8 h period, transiently increasing blood volume up to 85%over initial values, did not decrease Hct, indicating that injected Ringer...

... lung inflation, increased lymph sac pressure moves lymph to axillary regions, where lymph hearts can return lymph to the vascular space. Consequently, pulmonary ventilation has an important role for lymph movement and, hence, blood volume regulation in anurans. * Author for correspondence (e...

...P. J. Ponganis; G. L. Kooyman; R. Van Dam; Y. LeMaho ABSTRACT To evaluate blood N 2 uptake and the role of the respiratory volume (air sacs/lungs) as a N 2 and O 2 reservoir in deep-diving penguins, diving respiratory volume ( V DR), heart rate ( f H), venous , blood volume ( V b ) and hemoglobin...

.... Whole-body [ 51 Cr]RBC space was 9.9±0.6 µl g −1 body mass ( N =17). Blood volume calculated from [ 51 Cr]RBC space at 16 h and a dorsal aortic hematocrit of 24.5 % was 40.4 µl g −1 body mass. Whole-body [ 125 I]albumin space at 16 h was 118.0±7.4 µl g −1 body mass ( N =6), which resulted...

... and the animals died within a few hours. Evidence presented elsewhere has indicated that the site of the fluid uptake is the digestive gland appendages. Urine production would be continued or increased during the restoration of blood volume. When urine volume is added to the volume of fluid replaced, it appears...

...Harvey B. Lillywhite; Allan W. Smits ABSTRACT The lability of blood volume and its relationship to locomotor activity was investigated in two species of snakes Elaphe obsoleta , Say and Crotalus viridis , Rafinesque. Repetitive measurements of blood volume, determined from changes in the specific...
