title: Morphometric investigations on endocrine glands. IV. The rat thyroid during liver regeneration after partial hepatectomy with and without application of carcinogenic substances.
abstract: 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.
