Table 3 Effect of Ginkgo biloba extract on the levels of NP-SH in the stomachs of rats treated by gavages with 50% ethanol¹.

Treatment and dose	n	NP-SH concentrations (mg/100 mg /wet tissue, mean±SE)
Control (NS)	5	12.21±1.03
NS+50% EtOH (1 mL/rat)	5	2.82±1.32a
GbE (8.75 mg/kg)+50% EtOH	5	5.03±1.25c
GbE (17.5 mg/kg)+50% EtOH	5	5.66±1.82c
GbE (26.25 mg/kg)+50% EtOH	5	11.32±2.01c

¹NS, normal saline; GbE, Ginkgo biloba extract; EtOH, ethanol; NP-SH, non-protein sulfhydryils. Significantly different from the control (normal saline,

^aP<0.05). Significantly different from the ethanol treatment (^cP<0.05).
