Abstract

The aim of this study was to examine the effect of prolonged acclimation to cold on the acid-base status of extra- and intracellular fluids in the land snail Helix lucorum. For this purpose, acid-base parameters in the hemolymph and tissues were determined. In addition, the buffer values of hemolymph and tissues were determined in order to examine whether they change in the snails during acclimation to cold. According to the results presented, there is an inverse pH-temperature relationship in the hemolymph within the first day of acclimation, which is consistent with alphastat regulation. The Pco(2) decreased, and pH in the hemolymph (pH(e)) increased by 0.32 U within the first day of acclimation to cold, which corresponds to a change of 0.013 U degreesC(-1). After the first day of acclimation, Pco(2) increased in the hemolymph, resulting in a significant drop in pH(e) by 90 d of acclimation to cold. Acclimation of snails to low temperatures did not change the buffer value of the hemolymph. Also, intracellular pH (pH(i)) and intracellular buffer values remained stable during acclimation to cold for prolonged periods. The latter results in conjunction with those obtained by the invitro determination of the passive component of intracellular fluids indicate an active regulation of pH(i) in H. lucorum during acclimation to cold.
