A study was made of the capacity of insulinoma to catalyze the splitting of hippuryl-L-arginine (HA) and the contents of proinsulin-like component in the tissues of the tumours and in the blood serum of the patients. As revealed, in the absence of HA splitting by the tumour cytoplasmic fraction in the neutral pH zone there was noted a higher proinsulin-like component both in the tumour tissue and in the blood serum. An increase amount of proinsulin-like component in the blood serum stipulates possibly a more prolonged period of starvation before the occurrence of hypoglycemia, and a less pronounced picture of hypoglycemia in such patients in comparison with the patients whose tumours were capable of splitting HA similarly to the normal islands of Langerhans.

[Indirect lymphography of the thyroid gland. 2].

Indirect lymphography of the thyroid gland was performed in 144 patients. A conclusion was drawn that the use of superfluid oil contrast preparations of lipidol, miodyl type etc. in indirect lymphography of the thyroid gland will permit to obtain the exhaustive information on the state of the endocrine organ and regional lymph nodes. Lymphography with the aid of oil contrast preparation iodolipol diluted with ether and heated to the body temperature is less informative; water-soluble contrast agents were less effective. All the test contrast agents proved to be ineffective for detection of changes in the lymph nodes. Use of iodolipol for lymphography of the thyroid gland without preliminary mixture with ether is not recommended.

[Diagnosis of malignant thyroid tumors by indirect thyroid lymphography].

Indirect thyroidolymphography was used for 38 patients with malignant thyroid tumors. A conclusion has been made that indirect lymphography of the thyroid is a simple and rather informative diagnostic method for malignant thyroid tumors and should be followed by spot biopsy.
