Patients	WBC, × 103/µL	Hb, g/dL	AST (SGOT), IU/L	ALT (SGPT), IU/L	Cholesterol, mg/dL
Patient 1	5.6	17.0	39	64	199
Patient 2	5.4	17.5	44	67	173
Patient 3	4.2	16.4	28	58	179

Patient 5	6.1	18.4	101	151	231
Patient 6	7.5	15.6	33	42	195
Patient 7	8.2	17.1	35	54	175

WBC = white blood cell, Hb = hemoglobin, AST = aspartate aminotransferase, SGOT = serum glutamic oxaloacetic transaminase, ALT = alanine aminotransferase, SGPT = serum glutamic pyruvic transaminase.
