cases of coronary artery bypass grafting (CABG) were analyzed retrospectively. They were divided into four groups. In group 1 ( n =63,1985～1996), group 2 ( n =160, 1997～1999), and group 3 ( n =209, 2000～2002), CABG was performed with cardiopulmonary bypass (CPB). In group 4 ( n =291, 2000～2002) CABG was performed with off pump (OP). The durations of CPB and aortic cross clamp (ACC), temperature, hemodilusion, duration of using ventilator postoperatively, and ICU stay days were analyzed and compared. The patients in the groups 3 and 4 were older than those of the group 1, but younger than group 2. Pre operative supersonic EF value was lower in patients in the group 3 compared with group 2. A tendency of shortening of CPB time and ACC time, raising of temperature, lowering of hemodilusion, and shortening of ventilator time and ICU stay days could be discerned from group 1 down to group 4 ( P

OBJECTIVETo compare components in volatile oils of nutmeg and prepared nutmeg.

METHODVolatile oil from nutmeg and prepared nutmeg were extracted by vapor distillation. The chemical components in two kinds of volatile oils were determined and indentified by GC-MS.

RESULTThe change in quantity and quality of components in volatile oils were observed after processing. 13 new components occurred and 4 components disappeared in volatile oils after processing. The contents of methyleugenol and methylisoeugenol that are active ingredients were increased. The contents of myristicin and safrol that are toxic ingredients in volatile oils were decreased.

CONCLUSIONThe processing method of nutmeg by soaking with water and roasting with bran is scientific.
