The human red cell plasma membrane is extremely tight to Ca 2+ (the leak flux under the physiological gradient of 10V00 is 10-50 渭mole/I cells.h at 37掳C). The membrane contains an ATP dependent Ca 2+ pump, whose maximal capacity is of the order of 10 mmole/l cells.h at 37...
Homeostasisis the state of maintaining a constant composition of blood. 体内平衡是保持血液中成分稳定的状态. 辞典例句 It'serves distinct yet complementary function with the blood vascular system in maintaining tissuehomeostasis. 维持体内稳定,它属于血管系统,但也有其独立的功能. ...
Calcium (Ca2+) is an essential divalent cation involved in many bodily functions including bone composition, cell growth and division, blood clotting, and muscle contraction. The bone, intestine and kidneys are important for the maintenance of Ca2+ homeostasis. Ninety-nine percent of body Ca2+ is...
Some of these (bone formation, blood clotting, and cell adhesion) depend directly on the extracellular [Ca2+]; others depend directly on intracellular [Ca2+]. But since ICF [Ca2+] depends indirectly on plasma [Ca2+], all are linked to plasma [Ca2+].Calcium homeostasiscan be viewed as hav...

In healthy individuals, the buffering of metabolic acid is under control of the kidneys, lungs, and skeleton. In theory, when the diet is unable to provide sufficient buffering, the skeleton is utilized to maintain blood hydrogen ion concentrations, keeping pH between 7.35 and 7.45 (5) 展开 ...
The objective was to determine whether calcium homeostasis and bone turnover are affected by high-protein diets during weight maintenance (WM) and ED.Design: In a randomized, parallel-design, controlled trial of 32 men and 7 women, volunteers were assigned diets providing protein at 0.8 [Recommen...
Blood samples were analysed for ionized calcium, total calcium, calcitonin and pH. Plasma parathormone was assayed using a new and very sensitive N-terminal assay. Serum ionized calcium was significantly elevated by exercise at 50% of maximum aerobic capacity (VO2 max). The rise persisted until...
