[The effect of the sperm collection rhythm on the sperm production of insemination bulls in subtropical climate conditions].

A contribution is presented towards stabilizing the sperm production of A. I. bulls under subtropical conditions. The results are outlined of a production experiment on the influence of different sperm collection frequencies on the sperm production as found in 48 insemination bulls of a central bull station in the Syrian Arab Republic in the course of one year. It was found that a rhythm of 2 collections per bull and week provides favourable conditions for a stable and high-level sperm production.

Electron microscopic and ultracytochemical investigations of thyroid C cells in primary hyperparathyroidism.

The subject of study were C Cells of the human thyroid in course of primary hyperparathyroidism caused by the presence of a single adenoma. C cells were estimated by routine electron microscopic technique and by cytochemical cholinesterase (ChE) reaction according to Iwayama in electron microscopic technique. The presence of single C cells and of a small agglomeration of these cells, parafollicularily localized was found in the thyroid gland. An electron dense reaction product was noticed on membraneous structures of C cells of the thyroid.

Adrenal scintigraphy with 131-I-adosterol.

A new adrenal scanning agent, Adosterol (131I-6beta-iodomethyl-19-norcholest-5(10)-en-3beta-ol) has been evaluated in three female patients with hypercorticism. In one case, characterised by recurrent adrenocortical hyperactivity after bilateral adrenalectomy, a remnant of adrenal tissue was detected. In two other cases, the presence of an adrenal tumour could be excluded. The scan made on the 6th day after the administration of Adosterol was found to be superior in quality to that made on the 13th day.
