Pepsin in the toad Bufo marinus

Comparative Biochemistry and Physiology Part A: Physiology, 1986
The macroscopic localization of pepsinogen in the upper gastrointestinal tract of the anuran Bufo marinus was studied by means of biochemical assay. The pH optimum of the anuran pepsin was determined to be 1.6. The effect of lowered ambient temperature on stored pepsinogen and proteolytic activity was studied. Both parameters were reduced.

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.

Neurohypophysial function in the toad Bufo marinus

General and Comparative Endocrinology, 1967
Abstract A method for ureteral catheterization of the toad without need of surgical incision is described. Changes of ureteral urine flow and osmolality as well as the rate of bladder urine reabsorption were studied before and after the injection of hypertonic salt in the toad Bufo marinus.

Axoplasmic transport in the toad Bufo marinus

Brain Research, 1975
The rate and course of axoplasmic transport from the eighth dorsal root ganglion cell bodies into the sciatic nerve of the toad Bufo marinus were studied. Concentrated tritiated proline was hydraulically injected into a surgically exposed dorsal root ganglion of animals maintained at 19 +/- 0.5 degrees C.

Prolactin, calcitonin and blood calcium in the toads Bufo boreas and Bufo marinus

General and Comparative Endocrinology, 1971
Abstract Bufo boreas and B. marinus show a hypocalcemic response to a single injection of porcine calcitonin (significant in the latter). Chronic treatment results in hypercalcemia. Ovine prolactin treatment results in a tendency toward hypercalcemia in all cases, which was not significant in any single experiment.

Renal vascular anatomy of the toad (Bufo marinus)

Cell and Tissue Research, 1978
The renal vasculature of the toad, Bufo marinus, was studied mainly by means of scanning electron microscopy of vascular corrosion casts. All arterial branches terminated in a glomerulus. Each glomerulus was supplied by only one afferent arteriole. No shunts between afferent and efferent arterioles were observed.

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.
