To evaluate viability and severity of ischemically damaged myocardium, myocardial single emission tomography (SPECT) using 123I-BMIPP (BMIPP), a new tracer of myocardial metabolism of fatty acid, was performed before and after coronary artery bypass grafting (CABG). 201Tl myocardial SPECT (Tl) and left ventriculography (LVG) were also used. Thirty-three revascularized areas in eight patients were investigated. (1) Areas showing good redistribution on Tl and normal uptake on BMIPP indicated good viability and simple ischemic myocardium. Postoperative uptake of both tracers returned to normal levels. (2) Areas showing good redistribution on Tl and severely decreased uptake on BMIPP indicated jeopardized myocardium with severe ischemia. All such areas were seen in patients with unstable angina. Postoperative uptake of both tracers returned to normal levels. (3) Areas showing poor redistributionor severely decreased uptake on Tl and slight uptake on BMIPP indicating hibernating areas. Postoperative uptake became normal or better than preoperative uptake on Tl necrosis. However on BMIPP, the uptake was unchanged or recovered slightly. (4) Areas showing complete defect in Tl and BMIPP indicated necrosis and had no viability. Postoperatively the defect in both tracers were unchanged. Therefore, these areas required no revascularization. The ischemic state of myocardium could be assessed by evaluation of uptake patterns of BMIPP and Tl using myocardial SPECT. Therefore, using this new tracer of myocardial fatty acid metabolism “BMIPP”is useful for deciding culprit and viable lesions requiring coronary revascularization and evaluating therapeutical effects.

We purified a novel angiotensin-I converting enzyme (ACE) inhibitor from fish sauce Ishiru prepared from squid, and identified it as the tripeptide Leu-Ala-Arg (LAR). IC₅₀ of this ACE inhibitor was 2.5 μM, demonstrating high potency among peptides previously purified from fish sauces. Moreover, LAR acted as an antihypertensive peptide, reducing systolic blood pressure in spontaneously hypertensive rats.

Objective: The purpose of this study was to confirm the effect of feeding Okara fermented by Bacillus coagulans on cecum microflora in rat. Method: Three groups of SD rat of 8 weeks old were used in the experiment. The experimental animals were fed control diet, 2% okara diet, 2% fermented okara diet in each group for two weeks. The experimental diet and water were provided ad libitum. Food intake was measured every day. After 24 hours fast, we performed drawing blood with heparin after the experimental period. After drawing blood, several organs were removed for measuring their weight. In addition, we removed cecum after drawing blood about each three groups and studied their microflora. We also measured about plasma albumin, ALT, AST, ALP, LDH, total cholesterol, triacylglycerol, glucose, and cytokine level. Result: Bifidobacteria of cecum and blood IFN-g levels significantly increased in the fermented okara group. The total cholesterol level in blood significantly decreased. Conclusion: Okara fermented by Bacillus coagulans had an influence on not only intestinal microflora but also the immune system in rat, suggesting that the fermented okara can expect development as functional materials.

BACKGROUND: In Japan, there have been few reports about drug compliance, which is an important determinant of effectiveness, in the management of bronchial asthma patients. To clarify drug compliance and its relationship with various aspects of asthma management, a questionnaire survey was performed on asthmatic patients and their pharmacists.
METHODS: This survey was carried out, from October to November in 2001. The subjects were limited to the regular inhaled corticosteroid (ICS) users, and were restricted to patients whose medication had not been changed for at least 6 months before the survey. The questionnaires inquired about asthma status, various factors that have been reported to be associated with drug compliance and asthma management. Patients' pharmacists were asked about prescribed medications and drug compliance based on the pharmaceutical records.
RESULTS: Completed questionnaires were received from 610 patients. ICS compliance was not lower than that of anti-allergic drug but lower than that of oral sustained-released theophylline (OSRT) . Multiple regression analysis revealed a significant correlation between ICS and OSRT compliance.
CONCLUSION: These results might suggest that OSRT could improve patient's compliance to drug therapy through its bronchodilatory effect, thus resulting in better compliance to ICS. If this were the case, OSRT would play an important role in asthma management.
