TY - JOUR. T1 - Effect of activin A and follistatin on the release of pituitary hormones in the bullfrog Rana catesbeiana. AU - Koda, Aya. AU - Yamamoto, Kazutoshi. AU - Uchiyama, Hideho. AU - Vaudry, Hubert. AU - Kikuyama, Sakae. PY - 2000/9. Y1 - 2000/9. N2 - The effects of activin A and follistatin on the release of follicle-stimulating hormone (FSH), luteinizing hormone (LH), growth hormone (GH) and prolactin (PRL) from dispersed pituitary cells of the bullfrogs Rana catesbeiana were studied. Activin A stimulated the release of FSH, GH, and PRL dose-dependently, but not that of LH. Follistatin suppressed the activin-induced FSH, GH, and PRL release, but did not affect the basal secretion of those hormones. From the results obtained in this experiment, together with the previously obtained findings that activin B enhanced the release of FSH, LH, GH, and PRL, we conclude that activin A, in addition to activin B, influences the function of multiple types of pituitary cells in the ...

To test the susceptibility of bullfrogs (Rana catesbeiana) to amphibian chytridiomycosis, groups of captive bred, recently metamorphosed bullfrogs were inoculated with zoospores of Batrachochytrium dendrobatidis, the causative agent of chytridiomycosis, and assayed for clinical and pathological signs of infection. A novel technique for counting B. dendrobatidis zoospore inocula is described. Inoculation regimes varied from single exposures of 1-10 million zoospores per animal to inocula of 10 million zoospores per animal per day for a 31 day period. Twenty-five to fifty percent of each inoculated cohort was histologically positive for B. dendrobatidis on necropsy. However, lesions were focal, small with relatively little thickening of the keratinized epidermis and no clinical signs of chytridiomycosis were observed. Only one animal died during the experiment, due to cardiac puncture procedure. A fungal isolate used in these experiments was inoculated onto four metamorphosed poison dart frogs ...

TY - JOUR. T1 - Retention of nociceptor responses during deep barbiturate anesthesia in frogs. AU - Downes, Hall. AU - Koop, Dennis. AU - Klopfenstein, Bethany. AU - Lessov, Nickola. PY - 1999/10. Y1 - 1999/10. N2 - Bullfrogs (Rana catesbeiana) anesthetized with a large dose of thiopental (42.8 mg/kg) retained movement responses to nociceptor stimuli despite an average plasma drug level of 51 mg/l, of which 63% was bound to plasma proteins. This concentration, when corrected to include only unbound and uncharged drug, was 2-fold greater than those reported to abolish nociceptor response (NR) during surgical anesthesia in man. The median anesthetic dose (AD50) for loss of the righting reflex was 11.2 mg/kg by s.c. injection into the abdominal lymph sac; however, at 54.0 mg/kg, all frogs retained NRs, although otherwise deeply anesthetized. The ratio of NR-blocking dose to light AD was thus ,4.8, as compared to AB - Bullfrogs (Rana catesbeiana) anesthetized with a large dose of thiopental (42.8 ...

Learn about the American bullfrog, including their habitat, diet, range and population status, and where you can find them at the National Aquarium.

Bullfrogs, actually American bullfrogs (Rana catesbeiana), are native to almost all of eastern North America and south to Mexicos Isthmus of Tehuantepec. But they have also been introduced into swampy areas throughout much of North America, as far west as California and north to Canada. And it is likely that their range will continue to expand, as female bullfrogs can deposit huge egg-masses that can contain 20,000 eggs. Although those eggs and resultant tadpoles are subject to considerable predation, at least some of those baby bullfrogs are likely to survive. My bullfrog must have traveled overland as much as several miles to get into my pond. Yet bullfrogs can eat almost anything including other bullfrogs. Being cannibalistic, it is not unusual for a large adult to feed on its smaller companions. And when the adults grow up they also face the possibility of ending up as a human delicacy. Frog legs, fried to a golden brown and garnished with fried parsley and sliced lemon, can be superb ...

TY - JOUR. T1 - The secondary structure of a pyrimidine-guanine sequence-specific ribonuclease possessing cytotoxic activity from the oocytes of Rana catesbeiana. AU - Chen, Chinpan.

N2 - RC-RNase is a pyrimidine-guanine sequence-specific ribonuclease and a sialic-acid-binding lectin purified from Rana catesbeiana (bullfrog) oocytes. This 111-amino acid protein exhibits cytotoxicity toward several tumor cell lines. In this paper we report the assignments of proton NMR resonances and the identification of the secondary structure deduced from NOE constraints, chemical shift index, 3JNHα and amide proton exchange rates. The protein was directly isolated from bullfrog oocytes; we were able to assign all but five of the amino acid backbone protons of the unlabeled protein by analyzing a large set of two-dimensional proton NMR spectra obtained at several temperatures ...

Rabbits were immunized with frog or tadpole haemoglobin purified either by chromatography or by polyacrylamide gel electrophoresis. The obtained rabbit antisera were shown to be specific for frog or tadpole haemolysates by double diffusion, immunoprecipitation and immunofluorescence. Indirect immunofluorescent staining of peripheral blood smears of Rana catesbeiana tadpoles at the metamorphic climax revealed that 16% of the red cells were stained with antibodies against frog haemolysates, while almost all of them (98%) were stained with antibodies against tadpole haemolysates. These results are compatible with the possibility that some of the circulating red cells in metamorphosing tadpoles contain both tadpole and frog haemoglobins.. ...

I confirmed your identification, but it actually isnt possible to tell whether the frog in the picture is a bullfrog or a green frog. A clear picture of the back and head would have helped with identification. The backs of bullfrogs are smooth, while green frogs have a pair of ridges that run the length of the back, extending from just above their ear.. ...

Phenotypically similar species are hypothesized to adjust their behavior when they coexist to decrease competition. Pond-breeding frogs constitute an ideal system to address this hypothesis because multiple species may compete for noise-free periods to call for mates. American bullfrogs (Rana catesbeiana) and green frogs (R. clamitans) commonly co-occur in breeding ponds. Males of both species vocalize to defend territories and attract females. However, bullfrogs call more aggressively than green frogs and are expected to control access to the limiting acoustic resources. I predicted that green frogs increase chorusing activity in periods of bullfrog inactivity and that these patterns can be detected at both diel and seasonal scales. I used automated acoustic software to identify bullfrog and green frog vocalizations through two breeding seasons. Temporal partitioning occurs on a seasonal time scale. Bullfrog and green frog calling rates are both high early in the season in late May but then ...

Exposure of cells to environmental or chemical stressors will initiate the heat shock response, which is mediated by heat shock proteins. Heat shock proteins are molecular chaperones which are classified by size into six main families: HSP100, HSP90, HSP70, HSP60, HSP40 and the small heat shock proteins (sHsps). The sHsp family members bind to denatured proteins and maintain them in a folding competent state such that they may be refolded by other molecular chaperones. ,br /,,br /, The present study examined the expression and function of two amphibian sHsps, namely, ,em,Rana catesbeiana,/em, HSP30 and ,em,Xenopus laevis,/em, HSP27. Initially, an antisense riboprobe was produced to study the mRNA accumulation of ,em,Rana hsp30,/em, in cultured tongue fibroblast (FT) cells. Results showed that ,em,Rana hsp30,/em, mRNA was optimally induced when maintained at 35°C for 2 h.

Leukotriene (LT) C4, LTD4 and LTE4 have positive inotropic effects on contractility of the isolated perfused bullfrog heart. The effects of LTD4 and LTE4 but not LTC4 can be blocked by the mammalian antagonist L-649,923. Characterization of specific binding sites for [3H]LTC4 on membrane preparations from American bullfrog (Rana catesbeiana) ventricle was carried out. Binding assays were done in the presence of serine (5 mM) and borate (10 mM) for 30 min at 23 degrees C. Under these conditions, no metabolism of LTC4 to LTD4 occurred. Specific binding of [3H]LTC4 reached steady state within 10 min, remained constant for 60 min, and was reversible with the addition of 1000-fold excess unlabeled LTC4. Scatchard analysis of the binding data indicated a single class of binding sites with a Kd of 33.9 nM and maximal binding capacity of 51.6 pmol/mg of protein. Competition binding studies revealed an order of potency of LTC4 greater than LTD4 greater than LTE4 with Ki values of 47, 11766 and 32248 nM, ...

Dissection. Sacculi from adult American bullfrogs (Rana catesbeiana) were rapidly dissected into an oxygenated saline solution [containing (in mm): 120 NaCl, 2 KCl, 0.1 CaCl2, 3 dextrose, 5 HEPES, and 0.02% phenol red] and cleaned of extraneous tissue (Assad and Corey, 1992). The pH was adjusted to 7.23 with NaOH, and the final osmolarity was 250 mOsm/kg. Otolithic membranes overlying saccular epithelia were removed in fresh saline solution with fine forceps after incubation of the tissue in 75 μg/ml of subtilisin (Type XXVIII; Sigma, St. Louis, MO) for 20 min.. Immunohistochemistry. Tissues were fixed for 18 min in 4% formaldehyde in 80 mm sodium cacodylate buffer with 4 mm CaCl2, pH 7.35, at room temperature with gentle agitation. After fixation, tissues were rinsed (one time for 5 min) in 80 mm sodium cacodylate buffer without CaCl2 and (three times for 5 min each) in PBS (Life Technologies, Grand Island, NY) diluted to ∼250 mOsm, pH 7.4. This and all subsequent steps used PBS adjusted to ...

We studied the uptake of 2-deoxy-D-glucose (2DG) and the synthesis of its phosphorylated product 2DG-6-phosphate (2DG-6P) by the retinas of the clawed frog (Xenopus laevis) and the bullfrog (Rana catesbeiana). Autoradiographs showed that most of the retinal 2DG uptake is by the photoreceptor layer. The 2DG accumulation by isolated Xenopus retinas was time and concentration dependent. The Kt for transport was 5.05 mM; Vmax was 6.99 X 10(-10) mol . mg-1 tissue wet weight min-1. The Km for 2DG-6P formation was estimated to be 2-3 mM and Vmax to be approximately 4 x 10(-9) mol . mg-1 min-1. 2DG uptake was inhibited competitively by glucose with a Ki of 2.29 mM. Exposure to light reduced 2DG uptake by no more than 10% as compared with dark uptake. Low sodium or ouabain (10(-4)-10(-7) M) treatment did not significantly alter 2DG uptake as compared with control retinas. In experiments upon intact, anesthetized bullfrogs, light reduced both the total amount of radioactivity acquired by the retina and ...

The first question is the easier. Mathew Fisher, an epidemiologist at Imperial College, says trade is getting this thing from continent to continent ... it doesnt survive in salt water, and, as far as we know, has no airborne stage. The most likely kind of trade is a trade in amphibians and there are two main possibilities - the African clawed frog and the North American bullfrog. Both can act as carriers because they are relatively resistant to Bd. The clawed frog is used in research whilst the bullfrog provides the frogs legs used in some cuisines. Circumstantial evidence from the UK and the Phillippines points to the bullfrog ...

It seems that not only is H. occidualis very specific are where it settles, it will also adjust accordingly if the host is different, to the degree that it would do so even if it has already developed into a fully-fledged adult fluke. When the researchers conducted further experiments where they transplanted adult flukes from under the tongue of gray tree frogs to other species of frogs, the flukes were quick to adjust. When the flukes were transplanted from a gray tree frog to yet another gray tree frog or a green frog, the fluke will move to its usual spot under the hosts tongue, even though it is now in a new host. But if those flukes were transplanted to an American bullfrog, the flukes would migrate to the bullfrogs stomach. Furthermore, when those parasites were then extracted from the bullfrog and transplanted back to the tree frog, they went back to living underneath the hosts tongue ...

A big male American Bullfrog calls from the edge of a lake in the daytime. He sat making single calls every few minutes, until suddenly lots of other bullfrogs began calling all around him and then he made his full calls. Here we see him start with a full series of calls, then wait a bit before making a second series of calls, but this time starting with some longer notes before doing his typical calls. There was a second male about 10 feet from him who was silent, but after the first male makes his second full series of calls, the second male begins calling at 1 minute 10 seconds into the video. We cant see him, but his calls sound about as loud as the first frog, but you hear them when you can see that the first frog is silent. This calling disturbed the first frog so much, he made a short, sharp, territorial call and leaps in the air in the direction of the second frog. When I finally found him again, he was closer to the second frog, but the second frog hadnt moved ...

The modulation by muscarine or LHRH of the potassium M-current (IM) in whole-cell voltage-clamped bullfrog sympathetic neurons presents an initial phase of current reduction, followed, after agonist removal, by a transient enhancement or overrecovery. Employing a fast solution exchange system, an inhibitory process and an enhancing process were distinguished kinetically. The extent of overrecovery increased with the extent of the preceding inhibition. The rate and degree of inhibition increased with the concentration of agonist. In contrast, the rate of recovery and the extent of overrecovery were independent. The half-lives of the inhibitory and enhancing processes were 21 and 53 sec, respectively. Several observations suggest that arachidonic acid (AA) may be involved in overrecovery: (1) AA enhanced IM in a dose- dependent and reversible manner, with an IC50 of 2.8 microM. (2) Muscarine inhibited the A-current (IA), a potassium current that is blocked by AA. (3) Phospholipase A2 inhibitors ...

We identified four properties that reduced N-channel Po at depolarized voltages. These properties were null sweeps, low Po gating, inactivation, and slow activation. Several of these gating processes behaved in a manner consistent with the modal hypothesis. In particular, null sweeps were significantly clustered in the majority of our single N-channel patches. Clustering of null records has been reported for L-type calcium channels (Hess et al., 1984), skeletal muscle sodium channels (Horn et al., 1994), and N-type calcium channels (Rittenhouse and Hess, 1994). These clustered null sweeps were interpreted to result from a gating mode from which the channel will not open. Such a mode could be represented by a long-lived inactivated state that had a mean dwell time lasting several sweep intervals (4-6 s in our recordings). Whole-cell recordings have demonstrated an inactivation process from which N-current is slow to recover (Jones and Marks, 1989b).. In three single N-channel patches, we observed ...

mphibians are declining worldwide due to a variety of factors, including habitat loss and alteration, global climate change and predation and competition by non-native species. At the former Fort Ord in Monterey County, California the Bureau of Land Management (BLM) is attempting to document changes in amphibian populations by surveying each year. One of the concerns of the BLM is that the bullfrog (Rana catesbeiana), a non-native species, will negatively impact native amphibians living on the former Ft. Ord. Several sensitive species such as the California tiger salamander (Ambystoma tigrinum californiese), and the California red legged frog (Rana aurora draytonii) could be impacted. The 1999 survey include 3 vernal pools and 2 stock ponds and was completed between March 15 and May 2, 1999. This survey focused on the tadpole or larval stage of the amphibian life cycle. The results of the presence survey were analyzed using Sorensens coefficient or quotient of similarity. The vernal pools compared

Oxidative stress biomarkers, in vivo heart rate (f(H)), and contraction dynamics of ventricle strips of bullfrog (Lithobates catesbeiana) tadpoles were evaluated after 48 h of exposure to a sub-lethal concentration (1 ppm) of the herbicide Roundup Original (R) (glyphosate 41%). The activities of the antioxidant enzymes superoxide dismutase and catalase were increased in the liver and decreased in muscle, while oxidative damage to lipids increased above control values in both tissues, showing that the generation of reactive oxygen species and oxidative stress are involved in the toxicity induced by Roundup (R). Additionally, tadpoles hyperactivity was associated with tachycardia in vivo, probably due to a stress-induced adrenergic stimulation. Ventricle strips of Roundup (R)-exposed tadpoles (R-group) presented a faster relaxation and also a higher cardiac pumping capacity at the in vivo contraction frequency, indicating that bullfrog tadpoles were able to perform cardiac mechanistic adjustments ...

The American bullfrog is the largest frog found in BC. Adults can be up to 18-20 cm long, not including the legs. Bullfrogs were imported to BC for farming by frog leg farms.

Careful exploration has been made of the electrical activity of the brain of various mammals (Adrian and Matthews 1934; Gerard, Marshall and Saul 1936; Gerard 1936 a and b), but there has been very little study of the brains of other vertebrates (Adrian 1931; Umrath and Umrath 1934). The small size and relatively homogeneous cell population of the Amphibian brain offer certain advantages in analysis of the physicochemical factors determining activity; and further, the low metabolism of the poikilothermic brain at room temperature, together with the short distances for oxygen diffusion, suggested the possibility of studying sustained activity in the isolated organ. The present report covers a general exploration of spontaneous electrical changes in the neuraxis of the grass frog (Rana pipiens) and bull frog (R. catesbiana). ...
