Argatroban solution which was obtained by dissolving argatroban in 7.5% D-sorbitol-4% ethanol-hydrochloric acid (pH 1.5 to 1.7) was administered intraperitoneally in a dose of 1 ml/kg 15 min before the clamping of the common carotid arteries, and the controls were given the vehicle.

Defendant's first translation

A solution of argipidine dissolved in 7.5% D-sorbitol-4% ethanol with hydrochloric-acid acidity (pH 1.5~1.7) was administered intraperitoneally at a dose of 1 ml/kg 15 minutes prior to occlusion of the common carotid arteries.

Defendant's expert witness

A dose of 1ml/kg of a solution where argipidine was dissolved in 7.5% D-sorbitol-4% ethanol under hydrochloric acid acidity (pH of 1.5 to 1.7) was administered intraperitoneally 15 minutes before occlusion of the common carotid arteries.
