[Protein crystals and tubuli bundles in yeast cells. V. Enrichment of crystal and tubuli proteins during O2 limitation and anaerobiosis].

Cells of Saccharomyces carlsbergensis contain proteins assembling to crystals and bundles of tubules (tb) in the cyto- and karyoplasm by osmotic shock with hypertonic solutions. The cellular concentration of these proteins is regulated by oxygen pressure during growth. In cells grown at optimal aeration the protein level is low and crystals and tb cannot be induced. After a short period of O2-limitation or anerobic growth conditions the protein concentration increases and induction of crystals and tb is possible.

Anaerobiosis↗

[Alcohol dehydrogenase (ADH) in yeast cells. I. Cytoplasmic, mitochondrial and nuclear ADH in Saccharomyces carlsbergensis and Kluyveromyces fragilis].

When grown in a medium containing lactat, Saccharomyces carlsbergensis produces 5 times more ground-plasmatic ADH than Kluyveromyces fragilis. Upon gelectrophoresis, K. fragilis exhibits 7 bands while S. carlsbergensis shows only one. In a polyacrylamid gradient, the ADH's of both strains yield one band, the position of which corresponds to a molecular weight of about 160 000 D. In cell homogenates and mitochondrial fractions of S. carlsbergensis treated with ultrasound, an ADH is detected which exhibits 3 subbands and a molecular weight greater than 1 Megadalton. This ADH does not occur in K. fragilis. Mitochondrial fractions from K. fragilis contain an ADH, the electrophoretical mobility of which is identical to that of the ADH of the groundplasma. Nuclei of S. carlsbergensis also possess ADH whereas those of K. fragilis probably do not.

[Phlebographic diagnosis of leg edemas].

The most important preliminary examinations are: the visualisation of the valves of the veins by retrograde strain phlebography, determination of the degree of the recanalisation of the deep veins and the outflow of the pump of the calf muscle. Venous edemas: congenital absence of the valves of the veins, intramural thrombosis, postthrombotic edemas, division into four degrees, combined venous-lymphatic edemas.

[Disturbances of venous flow (author's transl)].

1. Local rupture of the veins by fracture. Compression and local spiral thrombi. 2. Failure of the venous pump at the ankle joint due to immobilization. 3. Failure of the pump in the calf muscles, leading to propagation of thrombi in the venae gastrocnemiae and in the veins of the soleus muscle, frequently with varicosity. 4. In 22 percent of left-sided fractures a venous spur is found in the left V. iliaca com.; increased likelihood of thrombosis in left leg in case of stasis due to immobilization.

Values, Myths, and Symbols.

Defining "symbol" as that which draws together and unites experience and "myth" as a cluster of symbols set in dramatic form, the author discusses the lack of both symbols and myths in contemporary sociaty. This lack had led to a disintegration of commonly held values and, ultimately, to a great need for psychotherapy on the part of individuals seeking personal identity. The individual must define his or her own values according to personal myths. One basic function of psychotherapy is to help individuals in their attempt to recover values.
