(a.) Maintaining a uniform temperature; haematothermal; homothermic; -- applied to warm-bodied animals, because they maintain a nearly uniform temperature in spite of the great variations in the surrounding air; in distinct from the cold-blooded (poikilothermal) animals, whose body temperature follows the variations in temperature of the surrounding medium.
Example Sentences:

(6) A greater amount of glial satellites, surrounding neurons, motor centers of the spinal cord and appearance of new variety of astrocytes and oligodendrocytes are observed in the homoiothermal animals.
(7) Antibody responses in homoiothermic and poikilothermic vertebrates are significantly different in their heterogeneity and affinity range, and in the speed of the secondary response following repeated antigenic stimulation.

(9) However, in comparison to human (HEF) and mouse (MEF) fibroblasts (homoiotherms) induced with NDV-R or poly I.poly C, interferon production in fibroblasts of spotted sousliks (SL) (heterotherm) and in the aneuploid line of mouse origin (L929) exhibits a greater cold resistance.
(10) The optimum temperature for Xenopus C activation is 25 degrees C. The ability of Xenopus antibody against chicken erythrocytes to co-operate with homoiothermic C in in vitro by lysis of chicken erythrocytes was tested.
(11) Therefore it seems probable that it exists in most, if not all, homoiotherm animal species.
(12) All the ECP samples were cytotoxic for fish and homoiothermic cell lines, possessed notable phospholipase activity and displayed haemolytic activity for sheep, salmon and turbot erythrocytes (but not for trout erythrocytes).
(13) isolated from fish and water tanks were simultaneously analyzed in poikilothermic and homoiothermic systems.
(14) Subnormal temperature was found to depress the production of interferon by cultures of fibroblasts of homoiotherms and heterotherms after virus or poly I.poly C induction.
(15) First homoiothermic reactions occur on the 2nd day of life and become effective on the 4th day.
(16) This may reflect a difference between poikilothermous and homoiothermous animals.
(17) Certain macroglial differences of the spinal cord in poikilothermal (Rana esculenta, Lacerta agilis) and in homoiothermal (Columba livia, Felis domesticus, Macaca rhesus) animals have been revealed.
(18) The results obtained indicate strong similarity between electrophysiological properties of the myocytes in the lymphatic vessels and those of the myocardial cells in homoiotherms.
(19) Because homoiothermic animals constitute an infinite heat reservoir, it is the transition temperature, Tt, not the endothermic heat of the transition, that determines the hydrophobically folded state of polypeptides at body temperature.
(20) Forty-seven subjects were classified as homoiothermics, thirty-one subjects as poikilothermics and forty-eight as-amphithermics.
Homothermic
Definition:
(a.) Alt. of Homothermous
Example Sentences:
(1) The rainbow trout lens was used as the poikilothermal lens and the rat lens as the homothermal lens.

(3) In poikilothermic 3-, 10- and homothermic 30-day-old rats ethylmorphine N-demethylation rate was dependent on incubation temperature (7, 20 and 37 degrees C).
(4) The response of the poikilothermal lens to various incubation temperatures in vitro was compared with that of the homothermal lens.
(5) Membrane response to the various temperatures as one of the external factors was investigated in the lenses of the poikilothermal animal and the homothermal animal.

(7) The rainbow trout lens was used as the poikilothermal material and the rat lens as the homothermal material.
(8) The power of the technique is illustrated by the ability to partially separate the evolutionarily closely related main homothermic species.
(9) Most work has concentrated upon juvenile fish or upon rapidly growing young market fish; these have high protein dietary requirements (30-50%) that are in direct contrast to the homothermic terrestial animals.
(10) This explains wide parasitic links of the tundra vole with other homothermic animals which especially extensive with the bank vole and it may have important consequences for epizootiology of tularemia and tick-borne encephalitis.
