    Notizen: Abstract. A vaccine solution of a formalin-killed culture of Vibrio anguillarum cells was observed to be toxic to young ayu when administered by the hyperosmotic infiltration method. The toxin was present in the culture broth. After the toxin was removed from the broth by centrifugation, the fish were dipped in 5.32% NaCl solution for 2 min and then in a solution containing precipitated cells for 3 min. The immunized fish were protected against vibriosis when challenged one month after immersion. The bacterin was administered to ayu by a further two methods, both using lyophilized whole cells of formalin-killed V. anguillarum. In one method, the fish were placed in a 5.32% NaCl solution for 2 min and then in a solution containing lyophilized cells at 2 g/l of well water for 3 min (two-step immersion). In the other method, the fish were placed in a 5.32% NaCl solution containing lyophilized cells also at 2 g/l for 3 min (one-step immersion). A high level of protection against artificial challenge was achieved with either method. No agglutinating antibodies to V. anguillarum were detected in either the serum or mucus of fish dipped in a vaccine solution, a supernatant, or a precipitated solution, one month after immersion. On the other hand, serum titres were detected in fish vaccinated by injection, although no titres were detected in mucus. LD50 values are presented for the virulence of the V. anguillarum strain. Compared to the original strain, virulence increased after the third passage in ayu, but decreased after the thirteenth passage in medium.

    Notizen: A 73-year-old woman had a walnut-sized tumor in I he occipital region for 10 year. The growth consisted of multiple small and large cystic epithelial masses. The cyst wall exhibited trichilemmal keratinization. Numerous squamous eddies as well as many glycogen-rich cells were present in the cyst wall. Some small round keratohyalin granules were observed in the cells below the horny layer. The desmosomes and masses of lipid droplets were seen in the horny layer. The findings described above are similar to those observed in the follicular isthmus and the follicular infundibulum. Other interesting findings include the presence of intranuclear inclusions of tonofilament-like material and/or keratohyalin-like granules within the cells near the mid-layer of the cyst wall.

    Notizen: Summary sinus pericranii has been reported to be situated usually along the midline. Two cases of laterally situated sinus pericranii are presented. Venous blood was obtained by puncturing the tumors directly. Injection of contrast medium into the tumors demonstrated a communication between the tumors and the intracranialvenous sinuses through marked diploic veins.

    Beschreibung / Inhaltsverzeichnis: Riassunto Film policristallini sottili di semiconduttore HgCr2Se4 sono stati preparati per la prima volta su substrati isolanti di cristalli singoli MgAl2O4 mediante deposizione a raggi molecolari e successiva tempra con HgSe. Si sono ottenute le condizioni ottimali per preparare film sottili a fase singola di HgCr2Se4. La resistenza magnetica e gli effetti di Hall di questi film sono stati misurati da 77 a 295 K in campi magnetici fino a 1.19·106 A/m. Diventa evidente che queste proprietà elettriche dei film sono influenzate da strati di interdiffusione nei film vicino ai substrati o dagli strati in disordine magnetico come i bordi amorfo o del grano in film.
    Kurzfassung: Резюме Впервые приготовлены поликристаллические тонкие пленки ферромагнитных полупроводников HgCr2Se на непроводящих монокристаллических подложках MgAl2O4 с помощью осаждения молекулярного пучка и последующего отжига с HgSe. Определяются оптимальные условия для приготовления тонких пленок HgCr2Se4, имеющих единственную фазу. Измеряются, магниторезистивный эффект и эффект Холла для этих пленок в области температур от 77 до 295 К и при магнитных полях вплоть до 1.19·106 А/м. Отмечается, что на электрические свойства этих пленок влияют слои в пленках вблизи подложки или магнитноразупорядоченные слои, такие как аморфные или зернистые границы в пленках.
    Notizen: Summary Polycrystalline thin films of the ferromagnetic semiconductor HgCr2Se4 have been prepared for the first time on insulating MgAl2O4 single-crystal substrates by molecular-beam deposition and subsequent annealing with HgSe. The optimum conditions for preparing single-phase thin films of HgCr2Se4 were obtained. The magnetoresistance and Hall effects of these films were measured from 77 to 295 K in magnetic fields up to 1.19·106 A/m. It becomes evident that these electrical properties of the films are affected by the interdiffusion layers in the films near the substrates or the magnetically disordered layers such as amorphous or grain boundaries in the films.

    Beschreibung / Inhaltsverzeichnis: Riassunto Si sono fatte misurazioni degli spettri di assorbimento di film sottili di HgCr2Se4 da 295 K a 25 K nell'intervallo di energia fotonica da 0.5 eV a 2.5 eV. Appare evidente che esiste un'ampia banda di assorbimento con un massimo a circa 0.93 eV a 295 K. Questa banda di assorbimento mostra uno spostamento nel rosso con la diminuzione della temperatura in corrispondenza della transizione dalla banda di valenza alla stretta banda di conduzione. Inoltre si trova che esistono altre transizioni con gap di energia di 1.20, 1.47 e 1.90 eV a 295 K. Come risultato di questa ricerca, si evidenzia la possibilità di costruire laser accordabili da questo materiale.
    Kurzfassung: Резюме Проведены измерения спектров поглощения для тонких пленок HgCr2Se4 в области температур от 295 до 25 К с жнергией фотонов от 0.5 до 2.5 зВ. Показано, что существует сирокая полоса поглощения с максимумом вблизи 0.93 зВ при 295 К. Жта полоса поглощения обнаруживает явление красного смещения с уменьшением температуры, соответсвующей переходу из валентной зоны в узкую зону проводимости. Кроме того, мы обнаружили, что существуют другие переходы 1.20, 1.47, и 1.90 зВ при 295 К. На основе проведенного исследования мы указываем на возможность создания перестраиваемых лазеров на жтом материале.
    Notizen: Summary Measurements of the absorption spectra for thin films of HgCr2Se4 were made from 295 K to 25 K in the photon energy range from 0.5 eV to 2.5 eV. It becomes evident that there exists a broad absorption band with a maximum at about 0.93 eV at 295 K. This absorption band shows a red-shift phenomenon with decreasing temperature corresponding to the transition from the valence band to the narrow conduction band. Furthermore, we find out that there exist other transitions with energy gaps of 1.20, 1.47 and 1.90 eV at 295 K. As a result of this investigation we point out the possibility of making tunable lases from this material.

    Notizen: Summary Testosterone, which was injected s.c. into adult male rats castrated 15 h prior to the injection, decreased the number of androgen-specific binding sites in the cytosol at 30 min. Coincidentally, a substantial increase was observed in the nucleus. The decreased number of the sites in the cytosol was restored to the initial level at 60 min; on the contrary, a decrease was observed in the nucleus.

    Notizen: Summary We studied the CT findings of 23 AVM cases confirmed by cerebral angiography and their clinical findings, and discussed mainly the lesions of ruptured AVM in the acute stage. The 10 cases, in which CT was performed within 7 days after the onset of a ruptured AVM, presented with blood stained CSF except for two cases. All of the 10 cases showed intracerebral haemorrhages in the CT findings, and four of these cases were associated with ventricular rupture. In the plain CT of these 10 cases, high density in the cerebral cistern, such as seen in the acute stage of ruptured intracranial aneurysms, was not found except for 1 case. In the enhanced CT within 7 days after the onset of ruptured AVM, no enhanced findings were found in eight cases. On the contrary, in 12 cases in which CT was performed later than the 8th day after the onset, enhanced findings were found in 11 cases. It has been previously reported that SAH is seen in the lesion of ruptured AVM in the acute stage. From our CT findings of ruptured AVM in the acute stage, however, it was concluded that the lesion of a ruptured AVM in the acute stage does nat cause SAH but an intracerebral haematoma or ventricular rupture and that blood may enter the CSF only secondarily.
