The fluorescence intensity of tocopherols originated from cold-pressed sunflower oil at different degree of oxidation in presence of l,2-dipalmitylo-sn-glicero-3- -fosfatidylocholine lipid (DPPC) membrane have been measured. It has been shown that fluorescence of tocopherol depends on amount of oil as well as on membrane concentration in the sample. Addition of oil with increasing peroxide value PV decreased the tocopherol fluorescence due to its disappearance in the sample. At constant membrane concentration chromatographically determined the amount of tocopherol in oil sample correlated with peroxide value and fluorescence intensity. Such results allowed us construct calibration curve which may be used for fast and accurate peroxide value determination using fluorescence technique.

The entire muscular system of the cercaria of D. pseudospathaceum was studied using a wholemount fluorescence technique with rhodamine-labelled phalloidin. The body-wall musculature of the main body consists of circular, longitudinal and diagonal muscles. The musculature of the tail, anterior organ, ventral sucker, and certain parts of the alimentary tract are distinct. The ultrastructure of the two main types of muscle cells (smooth and cross-striated) were described, as was the differentiation of smooth muscles in particular organs. Muscle cells with two major opposing systems of myofilaments were found in the oesophagus.
