“…quantities of the parotoid gland secretion of toads (genus Bufo) are lethal to many animals (see reviews by Kaiser and Michl, 1958;Michl and Kaiser, 1963). Brazil and Vellard (1926) recorded the death of nontoad-eating snakes (Crotalus and Lachesis) after being forced to bite toads (Bufo marinus), and Tschambers (1948) described the death of a frog-eating snake (Dinodon semicarinatum) after eating a toad (Bufo americanus).…”

“…Because the toad venom contains cardioactive steroids with digitalis-like effects (Michl and Kaiser, 1963), the response of the heart might be an appropriate guide to possible physiological differences in reac-tion to the venom. We have attempted to determine whether toad-eating and nontoadeating snakes differ in cardiac response, measured by electrocardiograms (ECG), after forced ingestion of parotoid venom.…”

Histochemistry of granular (poison) secretion in the skin of the frog, Rana pipiens

1973

View full text Add to dashboard Cite

There are two types of granular glands in the skin of leopard frogs (Rana pipiens). Cellular glands produce fine inbacellular granules rich in carbohydrate, carboxylic acids, tyrosine and sulfur-containing amino acids. Luminal glands consist of peripherally located nuclei with scant cytoplasm. Fine granular material in these glands resembles cellular gland secretion, except that the carbohydrate is less susceptible to periodate oxidation and that a diphenol (DOPA?) is present instead of tyrosine. The prominent lumen contains large granules composed of phospholipoprotein, and are also rich in primary catecholamine and a sulfur-containing amino acid. There was no evidence of 5-hydroxytryptamine or steroids.
