    Notes: Previously, authors developed a novel linear actuator with flat-ring-shaped magnets and applied it to a pump. In this article, the output power of the actuator and the efficiency of the pump are obtained by experiments. A pair of flat-ring-shaped Nd–Fe–B magnets having N and S poles on the surface are put on the same axis and face each other. Rotating one of the ring magnets in the direction of its circumference, an oscillating force occurs on the other magnet. When this magnet is restricted to linear motion along the axis, the mechanical power driving the rotating magnet is transferred to the linear motion power. A pump was made with this mechanism. The efficiency of the pump is experimentally obtained, where water pressure difference between the intake and the outlet has been changed. As a result, the efficiency of the pump attains to about 45%. The efficiency of the actuator itself is very high, because the actuator has no copper and iron losses, and a negligibly small eddy current loss. © 1998 American Institute of Physics.

    Notes: The energy distribution of the ion beam extracted from the compact microwave ion source for extremely low voltage ion extraction was measured with Ar and CO as a discharge gas. The energy distribution was measured by the retarding field method, and changes with respect to the change in gas pressure were observed. The obtained data were arranged by the peak energy and the energy spread. For both gases, the peak energy and the energy spread decreased with an increase in the gas pressure. The energy spread of approximately 5 eV with the peak energy of 15 eV were obtained for Ar gas at the pressure of 10−2 Pa. For CO gas, the peak energy was higher than Ar and approximately 20 eV. The energy spread was 6 eV at the pressure of 10−2 Pa. These values agreed with the peak energy and energy spread that were estimated previously from the mass spectra analysis. Since the ion source was designed to be used in the researches of low energy ion-solid interaction, these characteristics satisfy the requirements for this purpose. © 2002 American Institute of Physics.

    Notes: 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.

    Notes: 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.

    Notes: Summary. Beta interferon therapy was given to seven chronic hepatitis C patients with haemophilia or other haemorrhagic disorders who had received clotting factor replacement therapy. Serum alanine aminotransferase (ALT) levels ranged from 82 to 275 UL-1 and hepatitis C virus (HCV)-RNA ranged from 106 to 109 copies mL-1. HCV-genotypes were I+II in one patient, II in one, II+III in four and IV in one. Patients received 6 mega units (MU) daily of natural type beta interferon by intravenous infusion for 6 weeks. In three of seven patients, the protocol was modified to intermittent administration because neutrocytopenia (under 500 × 106 L-1) developed in two patients and thrombocytopenia (under 50 × 109 L-1) was observed in one during treatment. No modification was necessary with regard to daily and total dose. All patients received administration without any haemorrhagic complications. Six of seven patients showed improvement in serum ALT levels, and one of the patients showed normalization of ALT levels for 6 months after treatment. HCV-RNA disappeared in four patients by the end of treatment, although no one remained negative 6 months after treatment. The results of our study were similar to those reported in previous papers which described the use of alpha interferon in haemophiliacs. The reason none of the patients showed sustained loss of HCV-RNA after therapy might be associated with high HCV-RNA levels, characteristics of the HCV-genotype and prolonged duration of the disease.
