TL;DR: The glomerular capsules of 8 Bombinata toads have been tapped and radioiodinated human serum albumin when injected intraperitoneally was excreted by the toad glomerula into the primary urine and resorbed back by the tubuli in principle in the same ways as toad serum proteins.
Abstract: 1. The glomerular capsules of 8 Bombinata toads have been tapped. The glomerula have been found to excrete 0.035-0.15 μg of protein in about 0.11 μl of urine per hour, i. e., a 0.1 p.c. protein solution.2. Radioiodinated human serum albumin when injected intraperitoneally was excreted by the toad glomerula into the primary urine and resorbed back by the tubuli in principle in the same ways as toad serum proteins. However, the human albumin was excreted by the glomerula to a significantly larger extent than toad proteins.3. The concentration of both toad protein and ¹³¹I-labelled human albumin was approximately seven times lower in the bladder urine than in the primary urine.

TL;DR: The electrophoretogram revealed that both the patterns of parotoid gland extract and its secretion showed homology in protein bands with minor variations.
Abstract: Manuscript History: The present study was carried out to analyze qualitatively the Electrophoretic patterns of proteins in Parotoid gland extract and its secretion in terrestrial toad Bufo melanostictus (Indian toad). The patterns indicated that the gland extraction has higher number of protein bands compared to the gland secretion. The patterns of protein bands observed in the parotoid gland extraction of B. melanostictus using Sodium Dodecyl Sulphate Poly Acryl amide Gel Electrophoresis (SDS-PAGE) indicated a distinct pattern of four protein bands and some additional bands, with poor resolution, where as two protein bands in the parotoid gland secretion. The electrophoretogram revealed that both the patterns of parotoid gland extract and its secretion showed homology in protein bands with minor variations.

TL;DR: Data support the concept that cyclic AMP may be the mediator of PTH-induced phosphate transport inhibition in the toad bladder.
Abstract: Parathyroid hormone (PTH) inhibited active transport of inorganic phosphate and stimulated an increase in cyclic AMP concentration in the urinary bladder of the toad,Bufo marinus. Active transport of phosphate in the toad bladder was also inhibited by an analog of cyclic AMP (dibutyryl cyclic AMP) and by other drugs (pitressin and theophylline) which increase toad bladder intracellular cyclic AMP concentration. These data support the concept that cyclic AMP may be the mediator of PTH-induced phosphate transport inhibition in the toad bladder.
