Shark Rectal Gland

The inorganic ion content of rectal gland cells cultured from Squalus acanthias was studied by electron probe analysis in order to determine the effect of stimulation by cAMP. Cell sodium was reduced by 30% (P less than 0.01) at 8 min after exposure to dibutyryl cAMP and theophylline and remained low at 25 and 33 min. Chloride content also fell significantly with stimulation. Although cAMP may activate several transport sites, the results are consistent with a direct effect of stimulation to increase the activity of the sodium pump in shark rectal gland.

1. Osmotic adjustment is achieved by blood and intracellular fluids in the diamond-back terrapin when acclimatized either to fresh water or to sea water. 2. The muscle adjusts its composition to a higher blood osmotic pressure by greater concentrations in ammonia, in taurine and in urea and to a lesser extent in all amino acids (aspartate excepted). The inorganic ion content is not affected. 3. In the bladder mucosa ammonia, taurine and all amino acids are more concentrated in sea-water animals. But essentially urea is responsible for the higher osmotic pressure. Of the inorganic ions only potassium shows a (slight) increase in sea-water animals. 4. In the colon mucosa there is a slight increase in the total amino acid content, in the concentrations of sodium and chloride, and a larger increase in urea. 5. In the jejunum mucosa the concentrations of amino acids, urea and K are much higher in sea-water animals. 6. The results are discussed within the framework of isosmotic regulation of intracellular fluids.

Inorganic ion analyses were made on the mycelia and spores of five fungi: Linderina pennispora, Aspergillus niger, Spicaria elegans, and Penicillium claviforme and Penicillium roqueforti. The concentration of mineral elements in spores and mycelia of the five fungi varied with each element. The amount of Cu was consistently higher in spores than in mycelia. Zinc concentrations were higher in mycelia than in spores with the exception of A. niger. The concentration of Mg was higher in mycelia than in spores of the five species with the exception of L. pennispora. As with Mg, K concentrations varied considerably.
