Abstract
Summary
It was possible to demonstrate the reversible inactivation of calcification in vitro of the hypertrophic epiphyseal cartilage. When rachitic bone sections are shaken with strontium chloride, sodium chloride, calcification in vitro is inhibited. On subsequent shaking with calcium chloride calcification in vitro takes place. In addition, inactivation takes place with 1/2 mE of cupric chloride in the presence of 150 mE of calcium chloride. On subsequent shaking with 150 mE of calcium chloride (in the absence of cupric chloride) reactivation takes place.
