Osmotic Regulation in the Tadpoles of the Crab-eating Frog (rana Cancrivora)
The major features of the osmoregulatory mechanisms which form the basis for the unusually great salinity tolerance of the adults of the southeast Asian crab-eating frog (Rana cancrivora) have been described by Gordon, Schmidt-Nielsen & Kelly (1961) and by Schmidt-Nielsen & Lee (1962). Adults of this species respond to high external salinities with an increase in internal osmotic concentration,...
متن کاملNematodes of amphibians from Java, Indonesia, with a description of <br />new species, Meteterakis wonosoboensis n. sp. (Nematoda : Heterakoidea).
During a survey on the parasites of amphibians of Indonesia, toads (30 Bufo melanostictus) and 246 frogs (213 Fejervarya cancrivora, 11 F. limnocharis, 22 Rana macrodon from West Java and 68 F. cancrivora from Central Java) were examined for parasitic nematodes. Three species of nematodes were found and described, i.e. Meteterakis wonosoboensis n. sp. from Fejervaria cancrivora; Meteterakis jap...
متن کاملMorphological Differentiation and Adaptation of the Larvae of Rana berlandieri and Rana sphenocephala (Rana pipiens complex) in Sympatry
pipiens complex, were analyzed for morphological differentiation using multivariate techniques. Field-collected and laboratory-reared larvae of both species were compared for 12 morphometric characters. R. berlandieri larvae differ from R. sphenocephala larvae in having a more fusiform body shape, greater tail musculature development, a longer tail, relatively narrow dorsal and ventral tail fin...
متن کاملThe Epidermis of Rana Pipiens
The epidermis of adult Rana pipiens has been studied by electron microscopy and histological and histochemical methods. It was found that the epidermis is engaged in the production of both keratin and mucus. The basal cells are mainly filled with tonofilaments, whereas the cells located in the mid-portion of the epidermis contain both tonofilaments and mucous granules. Golgi vesicles and endopl...
متن کاملInhibition of Cell Proliferation by Rana catesbeiana and Rana japonica Lectins Belonging to the Ribonuclease Superfamily
Two frog egg lectins [Rana catesbeiana lectin (SBL-C) and Rana japonica lectin] preferentially agglutinate a large variety of human and animal tumor cells but not blood cells, lymphocytes, or fibroblasts. These lectins belong to the superfamily of pyrimidine base-specific RNases. The two lectins bound to a heparin-Sepharose column and were eluted from the column by an increase of NaC! molarity....
