    Notizen: Abstract The anti-inflammatory effects of recombinant human manganese superoxide dismutase on adjuvant arthritis was investigated. Local application of this manganese superoxide dismutase given every 2 days not only significantly reduced foot swelling but also retarded radiological bone destruction in adjuvant arthritis. Copper zinc superoxide dismutase had little effect on foot swelling.

    Notizen: Abstract We reviewed 12 cases of infarcts in the territory of the anterior choroidal artery (AChA) on CT and/or MRI. In each case vascular occlusion in the region was verified angiographically. Although the extent of the lesion on CT/MR images was variable, all were located on the axial images within an arcuate zone between the striatium anterolaterally and the thalamus posteromedially. The distribution of the lesions on mutiplanar MRI conformed well to the territory of the AChA demonstrated microangiographically. The variability of the extent of the infarcts may be explained by variations in the degree of occlusive changes in the AChA or the development of collateral circulation through anastomoses between the AChA and the posterior communicating and posterior cerebral arteries. The extent of the lesion appeared to be closely related to the degree of neurological deficit.

    Notizen: Abstract The distribution of the anterior choroidal artery (AChA) was analysed on coronal, sagittal and axial microangiograms of cadaver brains. On axial sections, the territory of the AChA was confirned to an arcuate zone between the striatum anterolaterally and the thalamus posteromedially. On sagittal sections, fine vessels from the cisternal part of the AChA were seen to extend upwards and somewhat posteriorly into the region of the posterior limb of the internal capsule. On coronal sections, ascending branches of the AChA coursed latcrally and then upwards to penetrate the globus pallidus and the inferior portion of the posterior limb of the internal capsule, apparently terminating at the lateral border of the thalamus. Determining the distribution of this artery on multiplanar sections was helpful for interpreting pathological changes, including infarcts, occurring in this region on multiplanar CT and/or MR images.

    Notizen: Abstract The gaseous viscosity of nitrous oxide (N2O) was measured in the critical region. The experimental temperature range was between 309.650 and 318.150 K and the pressure range was up to 9.6 MPa. The measurements were obtained with an oscillating-disk viscometer, combined with local determination of the density at the position of the oscillating disk, and they have an estimated accuracy of 0.6 % for viscosity and 0.5 % for gas density. The viscosity of N2O exhibits an anomalous increase near the critical point. The anomalous increase in viscosity was analyzed with the viscosity equation proposed by Basu and Sengers.

    Notizen: Abstract The liquid viscosity of six binary mixtures of HFC-134a with glycols [ethylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, polyethylene glycol(400), and polypropylene glyco](2000)] was measured in the temperature range from 273 to 333 K. The viscosity was measured with an improved capillary viscometer instead of the rolling-ball viscometer reported in our previous work. The measurement uncertainty was estimated to be 1.6%. Most of the present data are higher than previous data, and the gap between the two sets of data increases further in low-viscosity regions. The present results obtained with laminar flow are more reliable than previous results, which are indefinite because of the limit of usefulness of the rolling-ball viscometer in low-viscosity regions.

    Notizen: Abstract We investigated the olfactory response of the predatory mitePhytoseiulus persimilis to cucumber leaves infested with prey, the herbivorous spider miteTetranychus urticae. The predators responded to volatiles from young rather than old infested cucumber leaves. GC-MS analysis of the head-space of spider mite-infested, artificially damaged and undamaged cucumber plants showed that herbivore-induced plant volatiles were present among the volatiles of both old and young infested cucumber leaves. The major components of the herbivore-induced plant volatiles were (3E)-4,8-dimethyl-1,3,7-nonatriene and (E)-β-ocimene: these compounds are known to attract the predatory mites. In addition, we found three oximes (2-methylbutanalO-methyloxime, 3-methylbutanalO-methyloxime, and an unknown oxime) in the headspace of both old and young infested cucumber leaves. 3-MethylbutanalO-methyloxime and the unknown oxime were much more abundant in the headspace of infested old cucumber leaves. The potential adaptive value of differential attractiveness of cucumber plant leaves of different age is discussed.
