Corneal Toxicity Following Exposure to Asclepias Tuberosa
PURPOSE To present a case of corneal toxicity following exposure to milky plant latex from Asclepias tuberosa. METHODS A 70-year-old female presented with blurred vision and pain in her left eye after handling an Ascepias tuberosa. Clinical examination revealed a corneal stromal oedema with small epithelial defects. The corneal endothelium was intact and folds in Descemets membrane were obser...
متن کاملPregnane glycosides from the roots of Asclepias tuberosa.
Sixteen glycosides of pregnanes, including ikemagenin, lineolon, and a new pregnane, 3beta8beta,14beta,15beta,16alpha-pentahydroxy-++ +5alpha-pregnan-20-one, termed pleurogenin, were isolated from the roots of Asclepias tuberosa. Among ikemagenin and lineolon glycosides, one (1) was a known glycoside, and eight (2-7, 10, 13) were glycosides with new combinations of ikemagenin or lineolon and kn...
متن کامل8,12;8,20-Diepoxy-8,14-secopregnane glycosides from the aerial parts of Asclepias tuberosa.
Further study of constituents from the aerial parts of Asclepias tuberosa afforded twenty-two new steroidal glycosides along with tuberoside B(5) and G(5). These glycosides were confirmed to contain 8,12;8,20-diepoxy-8,14-secopregnanes, tuberogenin and its congeners, as their aglycones. The structure of each of these compounds was elucidated based on the interpretation of NMR and MS measurement...
متن کاملProperties of Single K and Cl Channels in Asclepias tuberosa Protoplasts.
Potassium and chloride channels were characterized in Asclepias tuberosa suspension cell derived protoplasts by patch voltage-clamp. Whole-cell currents and single channels in excised patches had linear instantaneous current-voltage relations, reversing at the Nernst potentials for K(+) and Cl(-), respectively. Whole cell K(+) currents activated exponentially during step depolarizations, while ...
متن کاملOccurrence of Dumontinia tuberosa in Korea
Thirty-seven single spore isolates were obtained from specimens of ascomycetous fruiting bodies collected from Mt. Suri, Anyang in Korea. The fungal specimens and isolates were identified as Dumontinia tuberosa based on their morphological and cultural characteristics. This is the first record of this fungus occurring in Korea.
