Effect of adrenalectomy on calcification of rabbit dentine and on the amount of serum calcium and total protein.

Since the adrenals are important endocrine glands, their effects on hard tissues like tooth and bone have already been investigated by many, for example, Ikuta4), Yonaga15), Falta2), Schour and Rogoff10), and others7)12)13). Recently, a new vital staining method for hard tissues was originated by Okada and Mimura8). Because the time marked in dentine by this method is evidently visible on its section, the details of development of hard tissues can be grasped exactly in time relation. Using this method, the author has made supplementary studies upon the effect of the adrenals on the development of hard tissues, and observed the changes of calcification and the relation between the growth speed and the amount of serum calcium or total protein much more exactly with regard to time than in any other previous reports.
