Lyophilized onion extract and ether extracts of onions were separated by chromatographic methods into several subfractions and tested for their effects on asthmatic reactions of guinea pigs to ...allergen, histamine, acetylcholine and platelet-activating factor (PAF) inhalation as well as on thromboxane biosynthesis of human platelets and lung fibroblasts. Onion oils are counteracting the bronchial obstruction due to PAF inhalation.
In spite of the large number of Chlamydomonas species which have been described, there is very little information on those occurring in marine or brackish environments. Many of the earlier ...descriptions may be disregarded as being not sufficiently complete for recognition (e.g. Schiller, 1913, 19255 West, 1916; Wille, 1903), whilst in recent years only a few marine species have been observed and studied in detail (Chadefaud, 1951; Dangeard, 1965; Ettl, 1967).
