The problem of misidentification between edible and poisonous wild plants: Reports from the Mediterranean area

2018

Abstract Today, in many European countries, people are looking for wild edible plants to experience new tastes and flavors, by following the new trend of being green and environmentally friendly. Young borage and spinach leaves can be easily confused by inexpert pickers with those of other plants, including poisonous ones, such as Mandragora autumnalis Bertol. (mandrake) or Digitalis purpurea L. (foxglove), common in southern and northern Italy respectively. In the last twenty years, several cases of intoxication by accidental ingestion of mandrake and foxglove have been reported. The purpose of this work was to perform a pharmacognostic characterization of young leaves from borage, mandrak…

Dose-response relationships and plasma concentrations of digitalis glycosides in man.

1978

An inter-individual, randomized, double-blind study of digitoxin (Dt) and β-acetyl digoxin (D) was performed in 120 healthy male volunteers. Groups of 10 persons each received orally D 0, 0.1, 0.2, 0.3, 0.4, 0.5 or 0.6 mg and Dt 0.04, 0.08, 0.12, or 0.16 mg daily for 7 days; Loading doses were given for the first three days. Plasma levels were measured with an86Rb-erythrocyte assay 24 h after the last dose. ECG, carotid artery pulse and phonocardiogram were recorded prior to (b) and 24 h after (a) the last dose. QTc, amplitude of T-waves in V2 to V6, electromechanical systole (QS2c) and left ventricular ejection time (LVETc) were measured. The differences between a and b (Δ-values) reflect …

Induction of digoxin-like material production, and the digoxin binding in the unicellular organism Tetrahymena by digitoxin.

1998

Thin layer chromatographic, and laser-confocal microscopic analyses with a monoclonal antibody to digoxin also displaying high affinity to digoxigenin, were used to determine the presence and localization of cardioactive glycosides. Tetrahymena pyriformis was found to possess digitoxigenin-like material, but digoxin, digitoxin, digoxigenin, gitoxin and lanatoside C were not detected. Digitoxin treatment elicited the appearance of a digoxin-like material in the progeny generations. Digoxin was taken up by untreated Tetrahymena, especially strongly 24 h after digitoxin treatment. While the cardenolide was localized in vesicles of the cell body in untreated Tetrahymena, the engulfed digoxin ap…

�ber den Einflu� von Digitoxigenin auf das Aktionspotential des Vorhofs euthyreoter und hyperthyreoter Meerschweinchen bei experimentellen Insuffizie…

1961

An isolierten Herzohren von Meerschweinchen wurden intracellulare Aktionspotentiale unter gleichzeitiger Registrierung der Kontraktionen abgeleitet. Untersucht wurde der Einflus des Digitoxigenins nach Barbituratschadigung und unter Calciummangel bei euthyreoten und hyperthyreoten Tieren.

1963

An isolierten, elektrisch gereizten Meerschweinchenvorhofen wurde das Verhalten der Kontraktionskraft und des cellularen Ca-Haushaltesunter dem Einflus von Digitoxigenin, Dihydrodigitoxigenin und 3α-Digitoxigenin uber einen weiten Dosierungsbereich vergleichend untersucht. Diese Substanzen zeigten betrachtliche Unterschiede in der Intensitat ihrer positiv inotropen und kontrakturerzeugenden Wirkung. Im positiv inotropen Dosierungsbereich verhielten sich die aquieffektiven Konzentrationen von Digitoxigenin, Dihydrodigitoxigenin und 3α-Digitoxigenin etwa wie 1:20:70. Bei der Messung des transmembranen Ca-Austausches mit 47Ca ergab sich unter Kontrollbedingungen eine nur partielle Markierbarke…

Quantitative Untersuchungen am Meerschweinchenvorhof �ber die Abh�ngigkeit der Digitoxigenin wirkung von der extracellul�ren Calciumkonzentration

1963

Es wurde uber einen weiten Bereich die Calciumkonzentration der Tyrodelosung verandert (0,9–9,0 mAq/l) und unter diesen Bedingungen die Konzentrationswirkungsbeziehungen fur verschiedene Digitoxigenindosen (1 × 10−7, 3 × 10−7, 5 × 10−7, 7 × 10−7 und 1 × 10−6 g/ml) am Meerschweinchenvorhof untersucht. Aus den Befunden geht hervor, das uber den gesamten untersuchten Bereich unter therapeutischen und toxischen Bedingungen ein eindeutiger Wirkungszusammenhang zwischen Digitoxigenin und Calcium besteht.
