Morphometric investigations on endocrine glands. IV. The rat thyroid during liver regeneration after partial hepatectomy with and without application of carcinogenic substances.
Morphometric studies and counting of mitoses in thyroids during regeneration after partial hepatectomy had the following results: 1. During the first days after surgical operation laparotomy caused only a slight reduction of the thyroid function. 2. Up to the 3rd day and especially on the 10th day after partial hepatectomy there is a higher relative percentage of the epithelium in the thyroid, but the mitoses are diminished. 3. Prefeeding with methylnitrosourea and acetylaminofluorene before the surgical 2/3 removal of the liver was answered with subactive thyroids on the 3rd day.
