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.

Seasonal comparison of the neuromuscular junction morphology of Bufo marinus [PDF]

Journal of Comparative Neurology, 2019
AbstractAt mammalian neuromuscular junctions (NMJs), prolonged inactivity leads to muscle denervation and atrophy. By contrast, amphibian NMJs do not show such degeneration even though they can remain in a state of drought‐imposed dormancy (hibernation) for many years.

The morphology and distribution of photoreceptors in the retina of Bufo marinus

Anatomy and Embryology, 1991
The number, cell morphology and retinal distribution of rods and cones were determined in the retina of the toad, Bufo marinus. Adult animals were sacrificed, both eyes were removed and prepared for either tangential section across the outer segments of the photoreceptor layer, or transverse section across the whole retina.

Skull allometry in the marine toad,Bufo marinus

Journal of Morphology, 1999
Scaling predictions pioneered by A.V. Hill state that isometric changes in kinematics result from isometric changes in size. These predictions have been difficult to support because few animals display truly isometric growth. An exception to this rule is said to be the toads in the genus Bufo, which can grow over three orders of magnitude. To determine

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 ...

Fate of exogenous marinobufagin-3H in Bufo marinus

Biochemical Pharmacology, 1969
Abstract After marinobufagin-3H was injected into toads, 80 per cent of the radioactivity could be extracted from various tissues 2–3 months later. One-half of the tissue radioactivity was found in the ovarian tissues, of which 80–90 per cent could be identified as unchanged marinobufagin by thin-layer chromatography and reverse isotope dilution ...

Retinal Projections in the Cane Toad, Bufo marinus

Brain, Behavior and Evolution, 2008
The location and extent of retinorecipient areas in the cane toad, Bufo marinus, were established by anterograde transport of cobaltic-lysine complex from the cut optic nerve. Most of the labeled optic axons travelled in the marginal optic tract, while others were in the axial optic tract, and/or the basal optic tract. Retinal projections terminated in

Spontaneous chromomycosis in the marine toad (Bufo marinus)

Journal of Comparative Pathology, 1992
Post-mortem examinations were performed on two marine toads, one animal showing neurological disorders and the other multifocal dermatitis. In one case, lesions consisted of a severe granulomatous encephalomyelitis and in the other of multiple granulomas in the nasal cavity, lungs, heart, bone marrow, ovaries and skin.

Innervation of the renal vasculature of the toad (Bufo marinus)

Cell and Tissue Research, 1983
The innervation of the dorsal aorta and renal vasculature in the toad (Bufo marinus) has been studied with both fluorescence and ultrastructural histochemistry. The innervation consists primarily of a dense plexus of adrenergic nerves associated with all levels of the preglomerular vasculature.

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.
