This treatise comprises three lectures delivered by Professor Stoll in the College of the Pharmaceutical Society of Great Britain under the auspices of the University of London. The first of these lectures is devoted to the importance of sugars in the plant economy and the classification of glycosides including a series of definitions of terms. In this lecture also the specific glycosides of digitalis and strophanthin are discussed. Great stress is laid on the structure of the sugars isolated from the cardiac glycosides. The historical features of the chemical and clinical events of significance in the development of these compounds ...

All experiments were performed in potassium free Ringer solution so as to be able to measure even minor changes in potassium concentration in the bath with sufficient accuracy. It is well known that muscle in potassium free Ringer solution loses potassium (Steinbach, 1940, 1951, 1952). Accordingly we found a mean loss of 0.0913 nM- in 10 minutes from a freshly dissected muscle if no drug was added. ...

Transmembrane potentials and contractile activity were recorded from isolated canine Purkinje and ventricular muscle preparations exposed to acetylstrophantidin (AS) and subjected to a resting tension equal to 80% of that required to elicit peak developed tension. AS induced transient depolarizations (TDs) accompanied by aftercontractions in Purkinje tissue. AS also induced aftercontractions in 11 muscle preparations, and in seven of these the mechanical events were associated with TDs. Aftercontractions and TDs in both and the coupling intervals were directly related to the preceding basic cycle length (BCL). The amplitudes of aftercontractions and TDs reached a maximum at a coupling interval of 600-700 msec. Tension increased the amplitude of TDs in Purkinje tissue and promoted the appearance of TDs in muscle. TDs in muscle occasionally reached threshold in the presence of tension. The results of this study suggest that stretch or increased resting tension may promote the types of ...

Acetylstrophanthidin, 0.3 to 10 µg/ml, caused contraction of helical strips of the dog cutaneous vein in an organ bath at 37°C. A latent period of 12 to 60 minutes preceded the contraction. During this time, the vein exhibited a progressive increase in response to transmural electric stimulation and added norepinephrine. As the dose of acetylstrophanthidin was increased, the latent period shortened and the increased response during the latent period was potentiated. When the contraction caused by 10 µg/ml was maximal, no additional contraction occurred with electric stimulation; the response to electric stimulation was only partially restored by the repeated washing out of the drug, despite relaxation of the strip to almost base-line tension. Since transmural electric stimulation causes contraction by release of tissue catecholamines, these experiments demonstrate that digitalis glycosides sensitize the cutaneous veins of the dog to adrenergic stimulation. This was confirmed in dogs ...

Kaslaste organismis paljuneb parasiit suguliselt, teistes peremeestes, kelleks on kõik püsisoojased loomad, toimub mittesuguline paljunemine. Parasiite leidub nakatunud loomadelt pärit toores ja vähe küpsetatud lihas ja muudes loomsetes saadustes, eriti veise-, sea-, lamba- ja ulukilihas. Parasiidiga võivad olla saastunud ka korralikult pesemata puu-, köögi- ja juurviljad. Parasiiti Toxoplasma gondii võib lühikese aja jooksul leiduda nakatunud kasside väljaheidetes ja pinnases, seega võib nakkuse saada aiatöid tehes ja liivakastis mängides, kui käed enne suuga kokkupuudet ja söömist pesemata jäetakse. Lapseootel naine võib nakkuse lootele edasi anda, mille tulemuseks võib olla nurisünnitus või tõsise silma- või ajukahjustusega lapse sünd.[1]. ...
