Histopathological examination revealed adreno-cortical carcinoma with microscopic lymphovascular invasion. Postoperative period was uneventful and is on follow-up for the last one year and is doing well.

The time-honored, useful, and frequently applied laboratory test of clinical medicine-the white blood cell count-is acquiring new meaning through recent discoveries in the basic sciences of medicine. The observation by Dougherty and White,16"17'19 and by Reinhardt, Aron, and Li,58 of the dissolution of lymphocytes by the action of adrenocortical hormone provokes reinterpretation of a number of ...

Alterations in platelet o2-adrenoceptor and mononuclear leucocyte ß2-adreno-ceptor characteristics in primary hypertension have been studied quite exten-sively The results of these studies are not consistent, which may be due to therelatively small number of subjects in most of the studies. In the present study,the o2-adrenoceptor characteristics were compared between 65 hyperte...
