It has been established that H+ secretion can be maintained in frog stomach in the absence of exogenous CO2 by using a nutrient bathing fluid containing 25 mM H2PO4 (pH approximately equal to 4.5) or by lowering the pH of a nonbuffered nutrient solution to about 3.0-3.6. Exogenous CO2 in the presence of these nutrient solutions uniformly caused a marked decrease in H+ secretion, PD, adn short-circuit current (Isc) and an increase in transmucosal resistance (R). Elevation of nutrient [k+] to 83 mM reduced R significantly but transiently without change in H+ when nutrient pH less than 5.0, whereas R returned to base line and H+ increased when nutrient pH greater than 5.0. Acidification of the nutrient medium in the presence of exogenous CO2 results in inhibition of the secretory pump, probably by decreasing intracellular pH, and also interferes with conductance at the nutrient membrane. Removal of exogenous CO2 from standard bicarbonate nutrient solution reduced by 50\% the H+, PD, and Isc without change in R; K+-free nutrient solutions reverse these changes in Isc and PD but not in H+. The dropping PD and rising R induced by K+-free nutrient solutions in 5\% CO2 - 95\% O2 are returned toward normal by 100\% O2. Our findings support an important role for exogenous CO2 in maintaining normal acid-base balance in frog mucosa by acting as an acidifying agent.

Recombination of ciliary dyneins of Tetrahymena pyriformis with the outer fibers was investigated using turbidimetry, co-sedimentation analysis and electron microscopy. As reported by Gibbons, 30S dynein could recombine with the outer fibers, while 14S dynein did to so a lesser extent. At acidic pH, however, most of the 14S dynein was also rebound to the outer fibers. When an excess of crude dynein fraction was added to the outer fiber fraction at pH 8.2, electron microscopic observations showed that the outer doublet microtubules were decorated not only with arms but also with other electron-dense materials. On the other hand, when crude dynein fraction was mixed with the outer fibers in an appropriate quantity, only arms were reconstituted at the regular positions of A-subfibers. ATP had an inhibitory effect on the recombination of dynein with the outer fibers.

A method is described for detecting the simultaneous presence of Fc and C3 receptors on mouse spleen cells. A proportion of both T cells and non-T cells bear both receptors. Both T-cell and non-T-cell Fc receptors were blocked by aggregated mouse IgG2 to the same degree. C3, but not Fc, receptors were blocked by factors present in the serum of irradiated mice or mice undergoing graft-versus-host reaction. Thymocytes activated by injection into irradiated F1 hybrid mice, and thymocytes regenerating after irradiation and bone marrow injection, appeared to have increased Fc receptors. A general role for Fc and C3 receptors in T cell-B cell co-operation is suggested.
