    Notizen: The pressure-volume isotherm and x-ray diffraction measurements for the coadsorption systems of krypton with methanol and ethanol on graphite have been carried out at 77 K. On graphite krypton and methanol are miscible while krypton and ethanol are immiscible. The two-dimensional solid solution of krypton and methanol takes an incommensurate triangular structure with an intermolecular distance ∼4.10 A(ring) and a molar composition Kr/CH3OH ∼0.6. Krypton adsorbed on top of the preadsorbed ethanol monolayer forms a triangular monolayer, incommensurate with the structure of the underlying monolayer. © 1995 American Institute of Physics.

    Notizen: The new monoclonal antibodies (MoAbs) E401, E811, E907 and E919 were prepared and characterized. These recognized an extracellular domain (amino acids No. 292–370) on the human c-erbB-2 gene product. Utilizing MoAb E811 and MoAb E919, a double determinant immunoassay (DDIA) was established to detect the soluble and the shed forms of the c-erbB-2 molecule. The levels of circulating erbB-2 antigen in the sera of patients with benign diseases and healthy controls were very low. The incidence of positivity for shed c-erbB-2 antigen in gastric cancer, eolonic cancer, gall-bladder caneer, pancreatic eancer and other cancers were 7.4%, 4.2%, 0%, 6.7% and 0%, respectively. Four of 54 patients with gastric carcinoma showed high levels of serum c-erbB-2 antigen. They belonged to clinical stage IV and their histological types were all well differentiated adenoeareinomas (two papillary and two tubular adenoeareinomas). Furthermore, the incidence of positive staining in gastric cancer was 34.6%; higher than that for shedding erbB-2 antigen. Most of the cases v-hich showed erbB-2 expression on cells were well-differentiated adenoeareinomas. Meanwhile, the distribution of erbB-2 antigen was limited in normal tissues. The results suggest that the expression of erbB-2 antigen is largely restricted to adenocarcinoma cells. It may not shed easily from these cells, and therefore It may be a very useful target molecule for passive immunotherapy.

    Notizen: Objective:  The aim of this study was to determine whether or not we could distinguish uterine papillary serous carcinoma (UPSC) from other types of endometrial cancer by cytology.Methods:  We examined the cytological findings of the endometrium from five cases with UPSC and compared them with 10 cases with endometrioid adenocarcinoma, grade 1 (G1). A morphometric analysis was performed. Cytological samples from the cervix and ascites of the patients with UPSC were also reviewed.Results:  All five patients had FIGO stage III and IV tumours. Three patients died of the disease and two are still alive with disease. The tumour cells of UPSC tended to be shed in papillary clusters with a tumour diathesis. Psammoma bodies were seen only in UPSC. The frequency of irregular-shaped nuclei, membrane thickness and eccentric nuclei in UPSC was higher than in G1. The chromatin pattern was coarsely granular, and both anisonucleosis and bare nuclei were prominent in UPSC. Cytomorphometrically, the maximum diameter of the nuclei in UPSC was significantly greater than that in G1. The nucleoli were also more often seen in UPSC than in G1. The findings of the nuclei and nucleoli in the cervical and peritoneal fluid cytology closely resembled those in endometrial smears. The features of the cervical smears and peritoneal fluid cytology were different from those of endometrial cytology regarding clear background and small clusters of cells.Conclusion:  As the endometrial cytology findings accurately suggested the histological diagnosis of UPSC, the diagnosis of UPSC was confirmed in this study by endometrial cytology. The cytological diagnosis of UPSC should be based on the findings of tumour diathesis, psammoma bodies and papillary clusters composed of tumour cells with enlarged nuclei and numerous nucleoli.

    Notizen: Objective:  Early cervical adenocarcinoma (ECA) with a tumour depth of 〈3 mm has a good prognosis. To clarify the cytological features of ECAs with depth 〈3 mm, these were compared with those of ECA with 3–5 mm and invasive adenocarcinoma (IA) invading the cervical wall with more than 5 mm in depth.Methods:  The cervical cytological features of ECAs with depth 〈3 mm (14 cases) were compared with those of ECA with 3–5 mm (four cases) and IA (13 cases). Cytologically, the presence or absence of tumour diathesis, number of atypical cells, crowded cell groups, groups with glandular structures, feathering, groups with palisading borders, rosettes, clusters, cell shape and size, nuclear shape and size, nucleolar shape and size, chromatin distribution, border and character of cytoplasm, and single cell pattern were evaluated.Results:  A tumour diathesis was seen in five of 14 ECA 〈3 mm in depth (36%), all four ECA with 3–5 mm (100%) and 11 of 13 IA with more than 5 mm (85%). Single cells, macronucleoli and coarsely granular chromatin pattern were less frequent in ECA of 〈3 mm than that in ECA with 3–5 mm and IA. The number of atypical cells and glandular structures in ECA was significantly less than that in IA. Cell crowding, feathering, palisading and rosettes were common in both ECA and IA.Conclusion:  The characteristic cytological features of ECA with depth 〈3 mm, having a good prognosis, were clean background, fewer single cells and macronucleoli, and less frequent coarsely granular chromatin pattern compared with those in ECA with 3–5 mm and IA. The number of atypical cells and glandular structures in ECA was significantly less than that in IA. Familiarity with the cytological features of ECA and its mimics is essential.

    Notizen: Abstract. The clinical and pathologic aspects of 34 cases of pure clear cell carcinoma of the ovary are discussed. These tumors represented 12.1% (34/280) of all ovarian cancers. The ages of the patients ranged from 34 to 78 years (mean 51.6 years) and 59% were postmenopausal. The clinical stages (FIGO) of these patients were as follows; I 22, II 5, III 6, and IV 1. Thirty-nine percent of the patients were nulligravidas. The diameters of the tumor varied from 6 to 31 cm (mean 16 cm), and 47% of the patients had endometriosis. Thirteen tumors were directly connected with endometriosis and this suggests that some ovarian clear cell carcinoma arose from the epithelium of an endometriotic cyst. Three architectural patterns (solid, papillary, and tubulocystic) were recognized. Forty-seven percent of the tumors were predominantly papillary and 24% contained mixtures of these three patterns. Four cell types such as clear, hobnail, eosinophilic, and flattened were also seen. Thirty-eight percent of the tumors had psammoma bodies. Histological patterns and cell types were not prognostic factors, and the stage at presentation was the most important prognostic factor. The 5-year survival rate was 54% (7/13) which was better than that in patients with serous adenocarcinoma of the ovary. The estimated survivals in patients with clear cell carcinoma however, were worse than those in patients with serous adenocarcinoma when compared stage for stage.

    Notizen: SUMMARY The effects of severing the hypoglossal nerve and resultant restriction of tongue movement was evaluated for its effect on masticatory jaw movement. Electromyograms of masseter muscles in the feeding rat were recorded 3 days after the nerve severing operation at 1 week intervals. Even after severing the lateral branches of the hypoglossal nerve bilaterally, active-feeding behaviour continued with mastication slightly impaired. After severing the medical branches bilaterally, feeding behaviour was rarely observed, but where eating did take place mastication was impaired with marked disturbance in the masticatory rhythm.
