    Notes: Summary Nine strains of influenza C virus were compared in their growth characteristics and viral polypeptides using LLCMK2 cells. The results suggested that influenza C virus undergoes genetic changes like influenza A or B virus.

    Notes: [Auszug] The experimental procedures used are almost identical to those of Tanaka and Masuda2. About 0.7 to 3 g of each sample was decomposed. Rare-earth elements (REE) were separated from the major elements by an AG50W-X8 resin column in HC1 media, while Ce and Nd were separated using an AG50W-X8 resin ...

    Notes: Summary The lactate dehydrogenase (LDH) isoenzyme patterns in benign and malignant brain tumours were determined by means of electrophoresis of the cell extracts and selective cytochemical stain of the smears. The LDH isoenzyme distribution of the cell extracts showed a pronounced cathodal shift in the malignant gliomas and metastatic carcinomas. Normal brain tissues and histologically benign gliomas, however, showed an anodal pattern with a dominance of the H-type LDH. Schwannomas and meningiomas had a midzone isoenzyme pattern with a dominant LDH3 fraction. Pituitary adenomas usually showed the LDH pattern similar to that of the normal cerebrum. The LDH M fraction could be cytochemically verified using an inhibitory effect by 2.6 M urea in staining. Astrocytomas grades 3–4 and metastatic carcinomas were characterized by loss or marked reduction of stainability by urea treatment, while astrocytomas grades 1–2 and oligodendrogliomas were resistant to urea inhibition.

    Notes: Summary The case involves a colloid cyst of the third ventricle in a 20-year-old man. The lining epithelia of the cyst were composed of two different types of epithelial cells; stratified squamous cells and mucincontaining columnar cells. The presence of both squamous and glandular cells in the cyst wall supports the contention that the colloid cyst in the present case derived from an non-neuroepithelial source. The clinico-pathology of this cystic tumor is compared here with other epithelial cysts of the central nervous system (CNS), especially Rathke's cyst.

    Description / Table of Contents: Résumé Les interactions de développement entre un endoparasitoïde grégaire,Apanteles kariyai Watanabe et son hôte,Leucania separata Walker, ont été étudiées. Le parasitoïde a pondu un plus grand nombre d'œufs dans l'hôte plus âgé. La taille de l'hôte a montré une augmentation graduelle avec l'avancement du stade larvaire, mais l'augmentation en nombre des œufs pondus par de parasitoïde n'a pas été parallèle à l'augmentation graduelle de la taille de l'hôte. Le poids net de l'hôte a été en corrélation positive avec le nombre des œufs pondus par le parasitoïde ainsi qu'avec le poids total des larves du parasitoïde. Par conséquent plus les parasitoïdes sont en nombre, plus ils contribuent à l'augmentation de la taille de l'hôte.
    Notes: Abstract The developmental interactions between a gregarious endoparasitoid,Apanteles kariyai Watanabe and its host,Leucania separata Walker, were investigated. The parasitoid laid more eggs in older hosts. Host size increased gradiently as the instar advanced, but the number of eggs laid per host did not increase accordingly. The net weight of the host was correlated positively with the number of eggs laid and with the total weight of parasitoids, especially in cases of parasitization at 3rd (5th-instar type), 4th and early 6th instar where the correlation was significant at 1% level. It follows therefore that the more parasitoids there are relative to their host size, the more they contribute to make the host size larger.

    Notes: Summary Hybridoma cell lines producing monoclonal antibodies against cowpox virus (CPV) and vaccinia virus (VV) were established to examine the specific and cross-reactive antigenic determinants of these viruses. Monoclonal antibodies against CPV (LB red strain) and VV (Lister strain and Ikeda strain) were classified into several groups on the basis of the results of immunofluorescence and haemagglutination inhibition tests. It was suggested that the groups defined above include the group of antibodies reacting with each of known major antigens of poxvirus, i.e. nucleoprotein (NP) antigen, heat labile and stable complex (LS) antigen, haemagglutinin (HA), cell surface antigen (CSA) and type A inclusion body (A).
