A study of lungs in Rana catesbeiana tadpoles
… respiration in the amphibians were made on Rana esculenta and Rana temporaria by Krogh (1904). He inserted a cannula connected to an air pump into the trachea and analyzed separately the air forced through the lungs by the pump and the air surrounding the frog. He was able to show that in R. …

Changes in gall bladder bile throughout development in Rana catesbeiana
The present study of Rana catesbeinana includes an analysis of the following throughout the course of post-embryonic development: the change in GI tract length and weight; the relative surfactant activity of the bile; the change in major bile pigments. The most rapid and profound morphological and …

The Post-Metamorphic Development of The Peripheral Auditory System of The Bullfrog, Rana Catesbeiana: An Anatomical and Physiological Study
… the peripheral auditory system of the bullfrog, Rana catesbeiana. The acoustic responses of single fibers of the VIIIth cranial nerve were studied in juvenile and adult frogs. Three populations of auditory fibers are found in both groups, but there is a downward shift in their best excitatory …

Identification and activity assessment of a bioactive peptide QUB-1368 from the skin secretion of the American bullfrog (Rana catesbeiana)
… peptide isolated from the skin secretions of Rana catesbeiana was named QUB-1368. After establishing the cDNA library, the biosynthetic precursor was obtained through molecular cloning, and then the mature peptide QUB-1368 was deduced from the precursor. QUB-1368 was then obtained in quantity …

Identification and activity assessment of a bioactive peptide QUB-2642 from the skin secretion of The American Bullfrog (Rana catesbeiana)
… identified as an analogue belonging to ranatuerin-1 family, was discovered in the skin secretions of The American Bullfrog (Rana catesbeiana) by ‘shotgun’ cloning. Using synthetic peptides, subsequent antimicrobial and haemolysis assays demonstrated that QUB-2642 had strong inhibitory …

Efficacy Of Constructed Wetlands Of Various Depths For Natural Amphibian Community Conservation
… primarily associated with permanent water, Rana catesbeiana (American bullfrog) and Notophthalmus viridescens (eastern newt), were in greater abundances than would occur naturally. Stomach contents of R. catesbeiana contained amphibian remains confirming interspecies predation. Further, in …
