Cytotoxicity and antimitotic activity of Rhinella schneideri and Rhinella marina venoms
Journal of Ethnopharmacology, 2019Rhinella schneideri and Rhinella marina are toad venoms distributed in different parts of the world, including Brazil, Columbia and amazon. Venoms extracted from different species have many clinical applications such as antimicrobial cardiotonics and treatment of cancer.

Recent reports have suggested that orexins, also known as hypocretins, play an important role in the modulation of respiratory control in mammals, but there are no data available describing the role of the orexinergic system in the peripheral and central chemoreception of non-mammalian vertebrates.

ABSTRACTParotoid glands of amphibians are known for the production of several biologically active compounds having pharmacological and toxic effects in mammals. In the present work, a protein fraction obtained from Rhinella schneideri parotoid gland (RsPP) was characterized to study its biological and toxic effects.

Introdução: substâncias químicas com capacidade de eliminar e/ou repelir insetos são denominadas inseticidas. Quando surgiu a necessidade do uso de inseticidas, foram utilizados compostos químicos altamente tóxicos e estes agiram não somente nos insetos, mas também nos seres humanos e no meio ambiente.

AbstractThis is the characterisation of the reproductive dynamics of Rhinella schneideri in an urban area during two non‐consecutive periods. Germ cells are similar to those of other anuran species, but some characteristics were more marked for R. schneideri, such as the morphological similarity of spermatogonia and oogonia, which may be related to ...

Stressors can increase plasma glucocorticoid (GC) levels and decrease plasma androgen levels in different species of vertebrates. GCs can have immune-enhancing or immunosuppressive effects, which are dependent upon stress duration and intensity. The worldwide decline in amphibian populations is strongly linked to an array of different stressors.
