[Size of the cell nucleus and nucleus-cytoplasm relations in pinealocytes in humans of middle and advanced age].

In the presented light microscope study, the question was examined of whether the size of the nucleus and nucleolus, respectively the nuclear:cytoplasmic ratio of pinealocytes, are changed in different human age groups. We investigated the pineals of 30 to 40-year-old men in comparison with those from patients who were older than 70 years. The investigation was performed with smears of the pineal gland which were stained according to Pappenheim (May-Grünwald and Giemsa method).

Volume, staging and grading of gastro-intestinal carcinoma--a population-based study.

All cases of the Regional Cancer Registry, North Baden who developed a gastro-intestinal cancer during the period 1975-1980 were re-examined according to the following parameters: tumor volume, pT stage, pN stage, grading. In the period considered, 8424 cases out of 14,061 cases with histologically proven gastrointestinal cancer could be grouped according to the pT stage. Most of the cases were operated at the pT2 or pT3 stage.
