Multiple endocrine neoplasia type 1 - a case report.

Unlabelled: Multiple endocrine neoplasia type 1 is a rare hereditary disease with an autosomal dominant type of inheritance characterized by high penetrance and the presence of hyperplasia and neoplasia in at least two different endocrine organs. The most often synchronously or consistently developing tumors are in the thyroid glands, the gastrointestinal tract and the adenohypophysis.

A Case Study: A patient 41-year-old with multiple endocrine neoplasia type 1 was treated with radiolabeled somatostatin analogues as a new promising treatment for patients with inoperable or metastatic neuroendocrine tumors.

Ultrastructural liver changes in the experimental thyrotoxicosis.

Aim of the study is to evaluate ultrastructural changes of rat liver in experimental thyrotoxicosis. For the study, 36 male rats have been utilized, weighing approximately 150-190 g, which were divided into three groups: the first, control group (12 animals) was composed of healthy rats that received intragastric sodium chloride 0.9% solution, the second group (12 animals) - animals with experimental thyrotoxicosis, which received intragastric solution of L-thyroxine at the rate of 200 μg/kg for 2 weeks, and the third group (12 animals) - rats with experimental thyrotoxicosis, which received intragastric solution of L-thyroxine at the rate of 200 μg/kg for 4 weeks.
