Secretion of calcium by rat submandibular glandAmerican Physiological Society - Tập 196 Số 3 - Trang 645-648 - 1959
Robert H. Dreisbach
The mean concentration of calcium in rat submandibular gland saliva after maximal pilocarpine stimulation was initially 3.2 µEq/gm and gradually fell during the 1st hour to 0.93 µEq/gm. The final concentration was approximately 30% of the concentration of calcium in the serum ultrafiltrate whether the total serum calcium was normal or elevated threefold by the infusion of calcium chloride...... hiện toàn bộ
Plasma volume, cell volume, total blood volume and Fcells factor in the normal and splenectomized Sherman ratAmerican Physiological Society - Tập 196 Số 1 - Trang 188-192 - 1958
Louise Wang
A method is described for the catheterization of the carotid of the rat which permits blood volume determinations to be made on unanesthetized animals. The cell volume (P32) and plasma volume (T-1824) were measured simultaneously on the day after catheterization. The average Fcells factor was 0.739 (S.D., 0.053) in 11 normal rats and 0.726 (S.D., ...... hiện toàn bộ
Liver and spleen as venous reservoirsAmerican Physiological Society - Tập 204 Số 1 - Trang 35-41 - 1963
Warren G. Guntheroth, G Mullins
The diameter of the liver and spleen was measured in 37 intact unanesthetized dogs. Fright always produced vigorous contraction of the spleen but no appreciable change in the liver. Running on a treadmill caused splenic contraction in only one-half the instances. The liver usually got larger or did not change with exercise. Epinephrine caused prompt contraction of the spleen and a variabl...... hiện toàn bộ
Hormone-substrate responses to total fasting in lean and obese miceAmerican Physiological Society - Tập 228 Số 1 - Trang 276-283 - 1975
G S Cuendet, E. G. Loten, D Cameron, A E Renold, Marliss Eb
The hormone-substrate milieu has been investigated in male fasted lean (C57BL/6-+/+) mice and mutant obese mice of the same strain (C57BL/6-obob). The lean mouse, in winter, mobilized insufficient fat (due to inadequate stores) to permit survival beyong 3 days and was unable to achieve any degree of conservation of vital protein stores. By contrast, in summer, the same animals survived 7 ...... hiện toàn bộ
Intracellular hydrogen ion changes and potassium movementAmerican Physiological Society - Tập 204 Số 5 - Trang 765-770 - 1963
E. B. Brown, Bernard Goott
Intracellular hydrogen ion concentration was determined on skeletal muscle by the DMO technique in dogs subjected to various acid-base alterations. The data verified the fact that a given alteration in Pco2 produces a larger hydrogen ion change in intracellular fluid than in extracellular fluid. In spite of this, however, the ratio (See PDF) decreased. On the basis of...... hiện toàn bộ
