[An example of oscillatory (cyclic) reaction for prostaglandin chemistry].

It is shown an ability of prostaglandin A1 to the oscillatory reaction which has significance both the theoretical and practical if prostaglandins are used for therapy.

[Marine fungus Stilbella aciculosa as a potential producer of prostaglandins].

The amount and composition of fatty acids in the fungus Stilbella aciculosa associated with the marine macroorganism Apostichopus japonica (trepang) were determined by gas-liquid chromatography and gas chromatography-mass spectrometry. In the culture liquid of S. aciculosa, prostaglandins (PG) of groups E and F were revealed by UV spectroscopy. This finding was confirmed by the presence of direct precursors of PG, polyunsaturated eicosapentaenoic and docosahexaenoic acids, in the culture liquid. The biomass of this fungus contained PG of group B.
