A morphological study has been undertaken on the capillaries of 9 microprolactinomas and 9 macroprolactinomas, surgically removed from untreated patients. The study was carried out utilizing light and electron microscopic techniques and electron microscopic morphometry. The frequency of the capillaries and their structural appearance were taken into(More)
The continuous muscle cell line BC3-H1, which expresses nicotinic Acetylcholine receptors (AChR) at the cell surface, was used to study the effect of lysosomotropic drugs on AChR degradation both in the normal condition and after stimulation induced by treatment with anti-AChR antibodies. We found that ammonium chloride, methylamine, and bacitracin(More)
Macrophages were isolated from poorly immunogenic metastatic sarcomas (mFS6 and MN/MCA1) of C57BL/6 origin. Tumor-associated macrophages (TAM) showed little release of superoxide when exposed to phorbol myristate acetate. When exposed to a phagocytic stimulus (zymosan), TAM released appreciable amounts of superoxide. TAM had a lower number of specific(More)
