A comparison of Ca2+-, Mg2+-ATPase and alkaline phosphatase activities of rat incisor pulp
A plasma membrane preparation derived from incisor pulps of 250-g rats was used as the source of alkaline phosphatase and an ATPase activated by either Ca2+ or Mg2+. Properties of the two enzymes were then compar...

Net uptake and release of calcium and phosphate by bonein vitro: Effects of medium calcium and phosphate concentrations
The effects of varying the initial calcium and phosphate concentrations of the culture media on bone calcium and phosphate release were examined, using whole calvaria from 3-day-old mice in 48-hour cultures. T...

Characteristics of calcium uptake by calcitonin-treated mouse calvariain vitro
The effect of calcitonin (CT) on calcium metabolism by bone was investigated in a stationary organ culture system, using half-calvaria from 5-day-old mice. CT induced the uptake of calcium by bones from the cu...

Effect of age on bone calcium and phosphate metabolism in organ culture
Calvaria taken from mice aged 0, 1, 3 and 5 days were cultured for 48 h, in control medium (no added hormone), or in the presence of PTH (0.5 U/ml) or CT (50 mCl/ml). In the control group, there was a shift fr...

Fluoride, parathyroid hormone and calcitonin: Effects on metabolic processes involved in bone resorption
The effects of fluoride, parathyroid hormone and calcitonin on acid production and bone phosphatases were investigated using half-calvaria of 5-day-old mice in a stationary culture system. Fluoride was incorpo...

Fluoride, parathyroid hormone and calcitonin: Inter-relationships in bone calcium metabolism
The influence of fluoride, parathyroid hormone and calcitonin on bone calcium metabolism was investigated in a bone culture system using half-calvaria of five-day old mice. Fluoride levels in the ash of half-c...
