Table 1. Half-time of Decrease of Electrically Stimulated and Caffeine-induced Ca²⁺Transients under Various Conditions

Mean ± SD.

*P < 0.05 compared with time control in the same solution.

PSS = physiologic saline solution; 0 Na⁺, 0 Ca²⁺= lithium chloride substituted for sodium chloride, 1 mm EGTA; TWI = electrically stimulated twitch; CAF = caffeine-induced contracture.
