The study between the dynamics and the X-ray anatomy and regularizing effect of gallbladder on bile duct sphincter of the dog

Table 1 The pressures of cCS and mOS segments before MgSO₄ infusion in interval period of bile draining (mmHg)

Group	cCSBP	mOSBP
Control (n = 7)	9.0 ± 2.0a	16.8 ± 0.5b
Study (n = 7)	14.0 ± 2.0	14.7 ± 0.7

^aP < 0.01, t = 6.195;

^bP < 0.05, t = 2.717. vs the study group.
