Urea transport in toad skin (Bufo marinus)

The Journal of Pharmacology and Experimental Therapeutics, 1993
Urea is transported from mucosa to serosa across the skin of the stenohaline toad, Bufo marinus, studied under short circuit current (SCC) conditions. Mucosal to serosal transepithelial urea transport (Jm-->s(urea)) was markedly and asymmetrically enhanced in toads adapted to hypertonic (150 mM) NaCl and showed saturation kinetics with an estimated Kd ...

Short-term storage of cane toad (Bufo marinus) gametes

Reproduction, 2001
The responses of cane toad (Bufo marinus) gametes, used as a model for the development of assisted reproduction techniques for rare and endangered amphibians, to short-term storage at temperatures > 0 degrees C were studied. Whole excised testes were stored at 0 degrees or 4 degrees C for 15 days, and sperm motility was measured at excision and ...

Ammonia transport by the urinary bladder of Bufo marinus

Comparative Biochemistry and Physiology Part A: Physiology, 1996
All experiments were performed in vitro on toad bladders. Bladder sacs from acidotic toads produced a concentration gradient across the bladder with both [NH3] and [NH4] higher in the mucosal media. By varying the pH of the serosal media, paired sacs from normal toads were incubated with similar [NH3] in the serosal media but a 75 fold difference in ...

Thermoregulatory behaviour in the toads Bufo marinus and Bufo cognatus

Journal of Thermal Biology, 1991
Abstract 1. 1.|The temperature preference of Bufo marinus in a linear thermal gradient over a 24 h period was measured in the spring using uniform light (UL) over the length of the gradient and in the spring and fall using a point source of light over the hot end of the gradient only (LH). 2.

Motor innervation of the toad iris (Bufo marinus)

American Journal of Physiology-Legacy Content, 1976
The sphincter pupillae muscle cells in the iris of Bufo marinus contract autonomously in response to bright light, causing a rapid constriction of the pupil. A strong sympathetic beta-adrenergic inhibition of the sphincter pupillae is apparent in this species. The inhibitory fibers can originate in the second, third, or fourth ventral spinal roots. No

Cholinesterases in the bladder of the toad (Bufo Marinus)

Biochemical Pharmacology, 1965
Abstract A study of the nature of the cholinesterases present in the bladder of the toad (Bufo marinus) has been undertaken in an attempt to explain why eserine fails to potentiate the responses to either applied acetylcholine or pelvic nerve stimulation.

Bufo marinus intoxication in dogs: 94 cases (1997–1998)

Journal of the American Veterinary Medical Association, 2000
Abstract Objective—To determine history, clinical and electrocardiographic abnormalities, treatment, and outcome of dogs exposed to toxins produced by the Bufo marinus toad. Design—Retrospective study. Animals—94 dogs. Procedure—Medical records of dogs examined between July 1997 and July 1998 for which a diagnosis

Characterization of cholinesterase of muscularis muscle of Bufo marinus

Comparative Biochemistry and Physiology Part C: Comparative Pharmacology, 1987
We have characterized the cholinesterase (ChE) of muscularis muscle of Bufo marinus by selectively using specific inhibitors of acetylcholinesterase and pseudocholinesterase and observing susceptibility to inhibition when substrate is present in excess.

LEPTOSPIRES IN THE MARINE TOAD (BUFO MARINUS) ON BARBADOS

Journal of Wildlife Diseases, 1988
Leptospires were isolated from the kidneys of four of 211 toads (Bufo marinus) caught on Barbados. Two of the isolates were identified as Leptospira interrogans serovar bim in the Autumnalis serogroup (the most common cause of leptospiral illness on Barbados), and two as possibly new serovars in the Australis serogroup.

Hemoglobin functions in the blood of Bufo marinus

Journal of Cellular Physiology, 1966
AbstractThe effects of three physical‐chemical factors, temperature, hydrogen ion concentration, and partial pressure of oxygen, on the respiratory functions of blood of the toad (Bufo marinus) have been studied.Measurements of oxygen affinity of hemoglobin in whole blood were measured tonometrically by a method devised for small quantities of blood ...
