PURPOSE: This study was performed to determine the incidence of BMM and to correlate the presence of these micrometastases with prognosis and othet clinicopathologic features. Materials AND Methods: BMM was evaluated in 220 breast cancer patients between July, 1991 and January, 1997, using mouse monoclonal antibody (AE1/AE3) against cytokeratin in an immunofluorescent assay. RESULTS: Of the 220 patients, 71 (32.3%) were positive for BMM. There were no association between bone marrow positivity and nodal status, TNM stage, known histopathologic parameters, and hormona1 receptor. Median follow-up for 220 patients was 41.6 month. The relapse rate was 16.8% (37/220). Twenty-four (33.8%) of 37 patients were positive for BMM and 13 (8.7%) were negative (p<0.05). Bone metastasis occurred in 16 cases, and was more common in BMM positive patients (14 of 24, 54.2%, versus 2 of 13, 15.4%, p < 0.05). Twenty-six patients were died of relapsed breast cancer. In overall survival, patients who was negative for BMM showed higher survival rate (p<0.05). CONCLUSION: BMM was a good predictor for distant metastasis, especially bone metastasis, and for poor prognosis. But no association was found between bone marrow positivity and tumor size, nodal status, stage, histologic parameter and hormonal receptor status.

In the present study the effect of exercise on the conversion rate of ingested glucose to glycogen in the different types of hindlimb skeletal muscles in Sprague-Dawley male rats was studied. The amounts of synthetized glycogen from ingested glucose of fast-twitch white (WV), fast-twitch red (RV), mixed type of fast-twitch white and red (EDL), and slow-twitch (SOL) muscles were determined at 30 and 90 min. after ingestion of 25% glucose solution which contained 14C-glucose(2 ml(luCi)/100gm B.W.) in control and exercise loaded rats. The result was summarized as follows: The about 55% at 30 min. and 70% at 90 min. after glucose ingestion were absorbed from gastrointestinal tract. This result shows no effects of exercise on absorption rate from gastrointestinal tract. The amount of synthetized glycogen of SOL from ingested glucose at 30 and 90 min. after glucose ingestion were highest, whether WV were lowest in hindlimb skeletal muscles in control and exercise loaded rats. In the exercise loaded rats, the amounts of synthetized glycogen of SOL, RV, and EDL at 90 min. after glucose ingestion was much higher than control rats, but not different in WV between exercise-loaded and control rats. At 30 min. after glucose ingestion, only SOL of exercise loaded rats was higher than control rats. In the control rat, the synthesis of glycogen was almost completed during initial 30 minutes. On the other hand, in the exercise loaded rat, except WV was opposite result of control rats, i.e., amounts of synthetized glycogen were major during late period. The amount of synthetized glycogen of liver at 30 and 90 min. after glucose ingestion in exercise loaded rats was higher than control rats. The rate of glycogen synthesis in control and exercise loaded rats were higher between 30-90 minute than initial 30 minutes.

Background: Fluvastatin is the first entirely synthetic 3-hydroxy-3-methylglutaryl-coenzyme A(HMG-CoA) reductase inhibitor. Clinical data indicate that this agent exhibits the proven efficacy of its class and also has some theoretical advantages in safety for long-term use because of its unique pharmacololgic property consistent with hepatoselectivity(i.e., low systemic exposure). This study is to evaluate efficacy and safety of fluvastatin in hypercholesterolemic patients in Korea. Methods: An open clinical trial with fluvastatin was conducted in 31 subjects who continued to have high blood cholesterol levels of 6.21 mmol/L(240 mg/dl) or greater after 1 month of lipid-lowering diet plus single blind placebo period. Fluvastatin was administered for 8 weeks with the initial dose of 20 mg per day and if serum cholesterol levels did not fall below 5.20 mmol/L(200 mg/dl) after 4 weeks the dose was increased to 40 mg per day for the second 4 weeks. On each visit every 4 weeks they underwent interview and laboratory tests about side effects and tolerability. Results: The mean % changes in plasma total cholesterol and LDL-cholesterol from baseline were

Rats were studied during 45 minutes treadmill exercise to determine the effects of hyperglycemia and hyperlipidemia on the utilization of cardiac muscle glycogen, and the utilization of diaphragm muscle glycogen was also studied for comparing to cardiac muscle. The hyperglycemia was produced by ingestion of 25% glucose solution(1ml/100gm, BW) and the hyperlipidemia by 10% intralipose ingestion(1ml/100gm, BW) with intraperitoneal injection of heparin(500 IU) 15 minutes before treadmill exercise. The mean blood glucose concentrations(mg/dL) in control and hyperglycemic rats were 110 and 145, respectively, and the mean plasma free fatty acid concentrations(micronEq/L) in control, control exercise(control-E) and hyperlipidemia exercise(HL-E) rats were 247, 260 and 444, respectively. In the hyperglycemic trial, the cardiac muscle glycogen concentration was not significantly decreased by the exercise but the concentration in control rats was decreased to 73.9%(p<0.05). The glycogen concentration of diaphragm was significantly decreased in both groups by the exercise, but the hyperglycemia decreased the glycogen utilization by approximately 10% compared to the control. The cardiac muscle glycogen concentration was not decreased by the exercise in control and hyperlipidemic rats but the utilization of glycogen in hyperlipidemic rats is lower than that of the control. These data illustrate the sparing effect of hyperglycemia on cardiac muscle glycogen usage during exercise, but the effect of hyperlipidemia was not conclusive. In the skeletal muscle, the usage of glycogen by exercise was spared by both hyperglycemia and hyperlipidemia.
