Abstract:
The size of myocardial infarct has been proposed as one of the important prognosis factors. In this study, we examined the effect of Kampo for the size limitation of myocardial infarct. Twenty male swine were used. A metal-coil was inserted in the left anterior descending coronary artery (LAD) of swine, in order to induce acute myocardial infarction (AMI). After occurrence of AMI, the swine were divided into four groups: Saiko-ka-ryukotsu-borei-to (TJ-12) group (n=5), Tokishakuyaku-san (TJ-23) group (n=5), Mokuboi to (TJ-36) group (n=5), and control group (n=5). Three kinds of Kampo formula were administrated via stomach tubes for four weeks. The control group received basal rations alone. The infarct size of the TJ-36 group was significantly smaller than that of the control (p<0.05). Each size of the TJ-12 and TJ-23 group had smaller tendency than that of the control, without significant difference. The histological character of the infarct in the control was numerous inflammatory cell infiltration and small foci of fresh coagulative necrosis in the border zone, which was not apparent in any Kampo administration group. We summarize that these Kampo, especially Moku-boi-to, inhibit the infarct size development. This inhibition is probably caused by suppression of harmful free radicals production from inflammatory cells, or by microcirculation improvement. This inhibitory effect by Kampo medicine led to rescue the border zone indicated as “jeopardized zone”.
