Calcitonin gene-related peptide (CGRP) - microadenomas of the thyroid gland induced by cadmium toxicity. Experimental study.

Purpose: The objective of our study was to make morphological and functional analysis of thyroid C cells in rats chronically exposed to cadmium (Cd).

Methods: The study was carried out on female albino Wistar rats (n=22, age=35-37 days, body mass 120-140 g), divided in control (n=11) and experimental group (n=11). The rats of the experimental group were treated with 15 mg/kg Cd dissolved (as CdCl(2)) in drinking water.
