Chloride balance in Rana pipiens

American Journal of Physiology-Legacy Content, 1975
Frogs kept in dilute solutions of Cl- maintain a steady state with respect to this ion. Chloride is exchanged at a rate of about 15 mumol 100 g-1 h-1 (47 nmol cm-2 h-1). Over 90% of the efflux is integumentary of which about 50% is diffusion of the total influx.

Photochemical activation of Rana pipiens tyrosinase

Biochemical and Biophysical Research Communications, 1975
Abstract Purified tyrosinase from Rana pipiens is activated by light. An action spectrum for the process indicates that there are two absorption bands responsible for the activation (290nm and 334nm). The kinetics of the photochemical process show an initial activation followed by inhibition. Molecular oxygen is required.

Experimental seizures in the frog (Rana pipiens)

Epilepsy Research, 1994
We investigated the effects of chemical convulsants in the leopard frog. Systemic kainic acid (5-20 mg/kg) caused limbic-like seizures, with staring, catatonia, fasciculations, and severe motor seizures, which were almost always lethal. Intracerebral electroencephalographic (EEG) recordings showed spike or spike-and-wave patterns at 6-8 Hz that ...

Tuberculosis in the Leopard Frog (Rana pipiens)

The Journal of Infectious Diseases, 1970
Amphibian tuberculosis differs from the more familiar mammalian tuberculosis in that it is generally less contagious and less devastating. Although a pulmonary form of amphibian tuberculosis is known to occur, most cases are the result of ingestion of the disease-producing organisms, and the lesions appear in the liver, spleen, kidneys, and testes.

Reflex habituation and potentiation in Rana pipiens

Animal Behaviour, 1965
Abstract This study was an attempt to further elucidate the nature of habituation. Two groups of frogs ( Rana pipiens ) were stimulated 100 times daily for 12 days with a No. 10 von Frey bristle. In one group, the locus of stimulation was maintained within the general area which elicits the wiping reflex of the ipsilateral hind foot.

Anaerobiosis in a frog, Rana pipiens

Journal of Experimental Zoology, 1967
AbstractRana pipiens shows an obvious reduction in hepatic, ventricular, and gastrocnemius muscle glycogen concentrations with increasing time in anoxia. Pulmonary repiratory movements drop sharply during the first three minutes of anoxia and virtually cease after 30 minutes.

The nucleolar chromosome in embryos of Rana pipiens

Experientia, 1977
Karyotype analyses of prometaphases from medullary plate cells derived from mid-neurulae of Rana pipiens have led to the identification of the nucleolar chromosome and nucleolar organizing region, which is located on the longer arm of a small sub-metacentric chromosome (No. 10).
