No difference was found in respect to the G-cell density between the group of prepyloric and that with duodenal bulb ulcer, although a lower pentagastrin stimulated acid output and consequently a smaller parietal cell mass appeared to be present in the first group as compared to the second. No relationship was found in either group between fasting levels of serum-gastrin and G-cell density, suggesting that no constant relationship exists between G-cell density and activity under basal conditions. A positive relationship, although statistically insignificant (0.05 less than P less than 0.1) between peak acid output and G-cell density in patients with duodenal bulb ulcer, indicates that in these patients the parietal cell mass and G-cell density are interrelated. The present study could not confirm the entity of antral G-cell hyperplasia in duodenal ulcer patients.","PeriodicalId":6953,"journal":{"name":"Acta pathologica et microbiologica Scandinavica.

A correlative cytological and histological study of 11 cases.","authors":"I Dahl, B Hagmar, L Angervall","doi":"","DOIUrl":"","url":null,"abstract":"Leiomyosarcoma of the soft tissues is a well-defined and characteristic entity histologically but correlative cytomorphological studies are lacking. A correlative histological and cytological study of 11 cases is presented. The leiomyosarcomas were characterized histologically by elongated tumour cells arranged in bundles intersecting each other at wide angles. The nuclei were elongated and often blunt-ended, tending to be aligned in tandem-position or in rows. The smears from leiomyosarcoma were poor in tumour cells and most cells were arranged in clusters of strands. The characteristic blunt-ended cells and nuclei of leiomyosarcoma could be identified in the smears and the nuclei were focally arranged in rows and sometimes in parallel. Nuclear atypia permits diagnosis of malignancy, although the atypia was generally not very pronounced. We consider that a knowledge of the corresponding histological features is mandatory for differentiating cytologically between various soft tissue sarcomas, including leiomyosarcomas. Further correlative cytological and histological studies of other soft tissue sarcomas are necessary for a more valid interpretation of the smears from leiomyosarcomas.","PeriodicalId":6953,"journal":{"name":"Acta pathologica et microbiologica Scandinavica.

Fifty-six out of 66 examined (i.e. 85%) revealed a monoclonal staining pattern for sIg, whereas 37/70 (53%) gave a monoclonal staining pattern for cIg by PAP. The methods combined gave a monoclonal staining pattern in 73/83, i.e. in 88%, of the biopsies tested. The discrepancies between the two methods were largest in centroblastic/centrocytic and lymphocytic lymphomas. With regard to the light chain staining patterns, complete agreement between the two methods was obtained in the 20 cases that allowed such analysis to be made. This suggests that the specificity of PAP, as carried out in this study with reagents purified by immunoabsorbent techniques, is satisfactory. On a basis of heavy chain isotypes centroblastic/centrocytic, lymphoplasmacytoid, and immunoblastic lymphomas could be divided into distinct immunological subgroups. In four biopsies the sIg heavy chains were mu + delta, whereas mu + gamma chains were detected by PAP. This finding may be relevant to the mu leads to gamma switch known to occur during normal B-cell differentiation. Immunoglobulin inclusions were found in 8 cases--3 belonging to the immunoblastic group, and 5 to the lymphoplasmacytoid group.","PeriodicalId":6953,"journal":{"name":"Acta pathologica et microbiologica Scandinavica.
