[Intra-articular injection of radioactive yttrium 90 in the hemophilic arthropathies. About nine cases (author's transl)].

The authors report 9 cases of intra-articular injection of radioactive yttrium 90. They specify the very place of this therapeutics in the hemophilic arthropathies treatment. Y 90 seems to give better results than osmic acid but cannot be used before the full growth.

[New approach to the study of the experimental inhibitory effect of the unicellular alga Chlorella pyrenoidosa against the murine sarcomas BP8 and L1210].

In this paper, the authors are relating the inhibitory effect of the unicellular alga Chlorella (Beijerinck, 1890) pyrenoidosa Zeitler and Lund, against the tumoural rodent strains BP8 and L1210, according to the amount of inoculum. The statistical study of the results allows to the conclusive fact of a real protective effect showed by this microorganism and of a demonstrative relation between the amount of the protective material and the tumoural answers the high amount giving a better inhibitory effect. The workers also insist on the lack of pathogenicity presented by the alga used in this study.
