[Solidscreen II Enzyme: a complete test method using Solidscreen II].

An extended application of the solid-phase antiglobulin test Solidscreen II consists in the use of enzyme-treated test cells. Beside the increased sensitivity in the detection of weak Rh antibodies, 'real enzyme-reactive antibodies' can be detected. A total of 818 serum samples and 404 EDTA plasma samples were tested for red cell antibodies.

Repression of endo-1,4-beta-glucanase formation in Penicillium janthinellum and product inhibition of its 1,4-beta-glucanases and cellobiases.

Endo-1,4-beta-glucanase formation of Penicillium janthinellum was repressed by glucose, sophorose, and glycerol. Chromatography on DEAE-Sephadex A-50 was employed to separate the 1,4-beta-glucanases from two cellobiases. The 1,4-beta-glucanases were inhibited competitively by cellobiose and glucose, and the two cellobiases were inhibited by glucose and glucono-delta-lactone.

[Comparison of the nuclear alterations induced by actinomysin D and alpha-amantine in hapatocytes of the rat (author's transl)].

Comparing the morphological effects of actinomycin D and alpha amanitine on the rat liver, it can be seen that the nuclear alterations caused by actinomycin (=segregation of the nucleolus and condensation of all the chromatin) occur simultaneously. After treatment with amanitine, the lesions appear in two steps. First of all one sees condensation of only the extranucleolar chromatin and fragmentation of the nucleolus.
