Search for polyprenols in leaves of evergreen and deciduous Ericaceae plants.

Various species and cultivars of Ericaceae family were checked for the presence of long-chain polyprenols in their leaves. In the genus Rhododendron no polyprenols were found in the ever-green species, while they were present in the deciduous type. The polyprenols were of chain-length of 14-20 isoprene residues and they occurred in the form of acetic acid esters. The polyprenol accumulation is discussed with respect to senescence of leaves.

On the specific pattern of long chain polyprenols in green needles of Pinus mugo Turra.

In green needles of Pinus mugo the most abundant polyprenols occur as a mixture of prenologues in which the dominant alcohol is built of 16 isoprene units. The characteristic spectrum of polyprenols (prenol-15, -16 and -17) was the same irrespective of the location of plant and of distinct morphological differences observed in the various selected forms of this species. The constant pattern of the polyprenols spectrum was preserved throughout the 2-year life span of needles, although the level of polyprenols was increased 2-3-fold. The polyprenol pattern in Pinaceae family differs from species to species, thus it may serve as chemotaxonomic criterion within this systematic group.

[High CA-125 values in miliary tuberculosis and ascites].

High levels of CA-125, the specific tumour marker for epithelial ovarian cancers are also found in inflammatory diseases of the pelvis. This case report of a 28 year-old woman with pathological CA-125 levels demonstrates the association between this finding and ascites caused by miliary tuberculosis. Tuberculostatic chemotherapy led to normalisation of the CA-125 levels within 8 weeks.

[Endodermal sinus tumor--a contribution to the clinical aspects of ovarian tumors].

Two cases of endodermal sinus tumor (EST) are described in a 19-year-old girl and a 50-year-old menopausal women, respectively. Exstirpation uteri totalis cum adnexis was carried out in both cases. According to the FIGO the tumors were classified as Ic. The histologic diagnosis of EST was based on the presence of elements such as extraembryonic mesoderm, yolk sac mesoderm, vascular structures with Schiller-Duval bodies, PAS-positive globules in Duval sinus spaces. In the first case, where the proposed chemotherapy was refused, the patient died 4 months later with symptoms of abdominal metastases. In the other case, chemotherapy was applied according to the VAC program. At 13 months of the treatment a relaparotomy was made and the lymphatic nodes taken showed no metastases. Three months later, the tumor relapsed and the patient died at 22 months of the therapy. In the light of their observations and literature data the authors recommended a radical surgical intervention combined with intense polychemotherapy as the only effective approach to the problem.
