Figure 3. Intracellular ionic strength of rat PCD cells after preconditioning in hypotonic medium (200 mosmol kg⁻¹) and subsequent re-exposure to isotonic medium (300 mosmol kg⁻¹).

Means ± s.e.m. for four to seven filters (5-8 intracellular analyses per filter). * Significantly different from value obtained in PCD cells kept at 300 mosmol kg⁻¹.
