    Notes: Summary The CT findings in 5 patients with cerebral paragonimiasis in the chronic state are presented. The findings were: 1) multiple, densely calcified areas with a variety of round or nodular shapes in the brain, 2) a large low density area surrounding or connecting with the calcified areas, and 3) cortical atrophy and ventricular dilatation. The relation between the CT findings and the previously reported plain skull X-ray findings or neuropathological findings are discussed.

    Notes: Summary Monoclonal antibodies against 3 different glycoproteins of bovine herpesvirus type 1 (BHV-1) involved in virus neutralization were used in indirect immunofluorescence (IIF) tests to characterize the appearance and transport to the plasma membrane of virus antigens in the infected cells. Antibodies against gp 117 and gp 71 glycoproteins first showed pronounced ring-like nuclear fluorescence at 4 hours post-infection (PI), followed by staining of the perinuclear region, presumably the Golgi apparatus. In contrast, antibody against gp 87 produced staining in cell-to-cell junctional areas at 3 hours PI before any staining close to the nucleus. The expression of the 3 glycoproteins at the surface of the infected cells was confirmed by the use of monoclonal antibodies having neutralizing activity, but not by non-neutralizing antibodies against gp 117 and gp 71. Non-neutralizing antibody against gp 87 detected the surface fluorescence only in those cells showing marked degeneration. Inhibition of glycosylation of the viral glycoproteins with tunicamycin (TM) was followed by interference with transport of gp 117 and gp 87 to the plasma membrane. On the other hand, gp 71 was incorporated into the plasma membrane despite the lack of N-linked glycosylation.

    Notes: Abstract Subretinal strands in proliferative vitreoretinopathy removed during vitreous surgery in ten cases were studied histologically; tissue culture was taken from five of the ten cases to obtain more material for investigation. Tissue culture was successful in all five cases. The cultured tissue just next to the original strand preserved the characteristics of the original tissue, whereas the portion distal from the original strand did not. Definite and/or suspected retinal pigment epithelial cells (RPE) were found in seven of ten original strands and four of five samples of cultured material. RPE were considered to be a predominant component of subretinal strands.

    Notes: Abstract Argon laser photocoagulation was placed on the confluent monolayer of cultured chick retinal pigment epithelial cells as a model of the regeneration process of retinal pigment epithelium after laser burn. The intense fibrillar net immunofluorescent pattern of fibronectin appeared on the burnt area from 2 h after the laser application, before the beginning of tissue reconstruction. Fibronectin was observed for several days, then became undetectable before the complete regeneration of retinal pigment epithelial cells. This indicates that fibronectin is involved in the early regeneration process of retinal pigment epithelium.

    Notes: Abstract A new-type redox battery has been developed. Some ruthenium complexes in organic electrolyte solution were utilized as the electrode active materials. A single cell consisting of [Ru(bpy)3]2+ complex in acetonitrile solution had an open circuit voltage of 2.6 V and a discharge current of 5 mA cm−2 (at a smooth carbon electrode). The characteristics of this type of cell were much influenced by such factors as the diaphragm material and the concentration of the complex. A cell with flowing electrolyte was also constructed and its charge-discharge performance was examined.

    Notes: Summary To elucidate the influence of muscle length on surface EMG wave form, comparisons were made of surface EMGs of the biceps and triceps brachii muscles during isometric contractions at different muscle lengths. Muscle lengths were altered by setting the elbow joint angle at several intervals between the limits of extension and flexion. The intensity of the isometric contractions was 25% of maximum voluntary contraction at the individual joint angles. Slowing was obvious in the EMG wave forms of biceps as muscle length increased. The so-called ‘Piper rhythm’ appeared when the muscle was more than moderately lengthened. The slowing trend with muscle lengthening, though less marked, was also seen in triceps. Zero-cross analysis revealed quasi-linear relationships between muscle length and slowing. Frequency analysis confirmed the development of ‘Piper rhythm’. An attempt was made to interpret the slowing associated with muscle lengthening in terms of the propagation of myoelectric signals in muscle fibers. Given the effect of muscle length on EMG wave forms, a careful control of joint angle may be required in assessing local muscle fatigue when using EMG spectral indices.

    Notes: A systematic study of static and kinetic phase behavior of deuterated polystyrene/poly(vinylmethylether) blends is presented in this paper. The static properties are studied by the small angle neutron scattering techniques and the kinetics of phase decomposition are studied by the temperature jump light scattering; technique. This procedure provides detailed information about phase behavior with regard to both thermodynamics and kinetics.

    Notes: This paper reports studies on polystyrene/poly-(vinylmethylether) blends to elucidate phase decomposition phenomena. Small angle neutron scattering (SANS) and temperature jump light scattering (TJLS) techniques were used to study both static and kinetic properties. The SANS methods were used to characterize the blends with respect to phase diagram, the Flory-Huggins interaction parameter, and the critical fluctuation length as a function of temperature. From the TJLS experiments, we have demonstrated the possibility of two kinds of phase decomposition mechanisms which should lead to distinct morphology and material properties.
