    Notizen: 〈list xml:id="l1" style="custom"〉1The age-related changes in mean arterial pressure (MAP), heart rate (HR), and baroreflex sensitivity (BRS) were studied in spontaneously hypertensive rats (SHR) and Wistar-Kyoto (WKY) rats from 4 to 20 weeks of age.2Intra-arterial blood pressure (BP) was continuously recorded for 24 h in conscious, freely moving rats. Twenty-four hour MAP and HR were calculated by an online computer. Baroreflex sensitivity was measured by phenylephrine infusion.3In SHR, BRS was significantly lower than in WKY as early as 4-5 weeks, at which time MAP in SHR was only slightly raised. During subsequent weeks, rapid increase in MAP occurred in SHR, in association with progressive bradycardia.4It was concluded that a reduced BRS may be detected in young prehypertensive SHR and this impairment of BRS may be central in origin.

    Notizen: Summary Polyacrylamide gel isoelectric focusing followed by electroblotting with enzyme immunoassay was done for the investigation of allotypes of properdin factor B (BF) in serum from 326 Japanese subjects. A new BF F variant tentatively designated BF*Fb1 (b=basic) was detected, the isoelectric point of each band of homozygous BF Fb1 being higher than of BF FF. Family data were in accordance with transmission by mendelian inheritance. The allele frequencies calculated from 326 Japanese subjects were 0.7945, 0.1825, 0.0215, and 0.0015 for BF*S, BF*F, BF*Fb1, and BF*F075, respectively, with that of variant BF*Fb1 being a polymorphic frequency. The distribution of phenotypes fitted the Hardy-Weinberg equilibrium.

    Notizen: Summary Syringobulbia with a large syrinx was revealed by MR imaging. The syrinx extended from the medulla to vertebral level T10. We suspect that this giant syrinx may be produced by a congenital meningioma at C7, generating pulsatile flow in the original syrinx and causing a giant syrinx.

    Notizen: Summary We report a Garcin syndrome due to nasopharyngeal carcinoma invading the skull base. MR Imaging of this patient shows the position of the tumour and reveals how the tumor invaded the skull and the effect of treatment.

    Notizen: Summary Genetic polymorphism of human factor I (C3b inactivator) has been described using polyacrylamide gel isoelectric focusing electrophoresis of neuraminidase-treated EDTA plasma samples followed by electrophoretic blotting technique. In 435 individuals three different common patterns were observed, and these were controlled by two common alleles at a single locus. The results of typing family material confirmed autosomal codominant Mendelian inheritance. Two common alleles were designated FI*B and FI*A, and gene frequencies were estimated to be 0.8931 and 0.1069 for FI*B and FI*A, respectively. The distribution of phenotypes fitted the Hardy-Weinberg equilibrium. Linkage studies failed to show close linkage between factor I and the major histocompatibility complex.

    Notizen: Abstract Maximal immersions of a surfaceM 2 inton-dimensional Lorentz space which are isometric to a fixed holomorphic mapping ofM 2 into complex Lorentz space are determined. The main tool is an adaption of Calabi's Rigidity Theorem. Such an adaption is necessary because of the existence of degenerate hyperplanes in complex Lorentz space.

    Notizen: Abstract Trace elements in two species of whale tapeworms,Diphyllobothrium macroovatum andDiplogonoporus balaenopterae, were analysed by atomic absorption spectroscopy. Six elements (Fe, Cu, Zn, Mn, Cd, Ca) were assayed from different regions of two tapeworms: scolex, neck, immature, mature and gravid proglottids. Whole strobilae at different stages of maturity were also examined. The relationship between the trace element content and the physiological significance is discussed.

    Notizen: Abstract The early development of four Diphyllobothrium species, D. latum, D. dendriticum, D. ditremum, and D. vogeli, are described. D. latum sheds the entire larval body easily and shows a high shedding rate of 82.1% on average. On the other hand, D. dendriticum exhibits a different developmental pattern, with a low shedding rate of 8.7% in the hamster and a high shedding rate of 34.9% in the rat. D. ditremum is difficult to recover from hamsters but shows a high shedding rate of 42.9%. D. vogeli shows a constant recovery rate of 38.3% without shedding. The species specificity of these four diphyllobothriids is discussed briefly in relation to the early developmental pattern and the growth rate.

    Notizen: Abstract Three-dimensional observation was carried out on plerocercoids and adults ofDiphyllobothrium dendriticum, D. ditremum, D. latum, andD. vogeli using scanning electron microscopy. The species-specific differences between plerocercoids were recognized in the shapes of the whole body, scolex, and bothrium and the wrinkle pattern on the body surface. The differences between adult worms were also observed in the shapes of the scolex, neck, and genital papillae around the genital pore and the pattern on the egg surface. The significance of species specificity in the three-dimensional morphology of diphyllobothriid cestodes is briefly discussed.
