Abstract:To survive, organisms must adapt to changes in the ambient environment. Here, we describe a new model of anemia based on exposure of African clawed frog, Xenopus laevis to low-temperature. Frogs exposed at low-temperature (5ºC) for five days had decreased numbers of peripheral blood erythrocytes, leukocytes, and thrombocytes as well as low hemoglobin levels. By contrast, spleen erythrocytes increased in number. Cell counts returned to normal in frogs re-warmed at ambient temperature (22ºC) for two days. To con… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
