Abstract
We examined the safety and the effects of low-intensity resistance training (RT) with moderate blood flow restriction (KAATSU RT) on muscle strength and size in patients early after cardiac surgery. Cardiac patients (age 69.6 ± 12.6 years, n = 21, M = 18) were randomly assigned to the control (n = 10) and the KAATSU RT group (n = 11). All patients had received a standard aerobic cardiac rehabilitation program. The KAATSU RT group additionally executed low-intensity leg extension and leg press exercises with moderate blood flow restriction twice a week for 3 months. RT-intensity and volume were increased gradually. We evaluated the anterior mid-thigh thickness (MTH), skeletal muscle mass index (SMI), handgrip strength, knee extensor strength, and walking speed at baseline, 5-7 days after cardiac surgery, and after 3 months. A physician monitored the electrocardiogram, rate of perceived exertion, and the color of the lower limbs during KAATSU RT. Creatine phosphokinase (CPK) and D-dimer were measured at baseline and after 3 months. There were no side effects during KAATSU RT. CPK and D-dimer were normal after 3 months. MTH, SMI, walking speed, and knee extensor strength increased after 3 months with KAATSU RT compared with baseline. Relatively low vs. high physical functioning patients tended to increase physical function more after 3 months with KAATSU RT. Low-intensity KAATSU RT as an adjuvant to standard cardiac rehabilitation can safely increase skeletal muscle strength and size in cardiovascular surgery patients.

Abstract
Malnutrition is associated with sarcopenia, cachexia, and prognosis. We investigated the usefulness of phase angle (PhA) as a marker of sarcopenia, cachexia, and malnutrition in 412 hospitalized patients with cardiovascular disease. We analyzed body composition with bioelectrical impedance analysis, and nutritional status such as controlling nutritional status (CONUT) score. Both skeletal muscle mass index (SMI) and PhA correlated with age, grip strength and knee extension strength (p < 0.0001) in both sexes. The SMI value correlated with CONUT score, Hb, and Alb in males. Phase angle also correlated with CONUT score, Hb, and Alb in males, and more strongly associated with these nutritional aspects. In females, PhA was correlated with Hb and Alb (p < 0.001). In both sexes, sarcopenia incidence was 31.6% and 32.4%; PhA cut-off in patients with sarcopenia was 4.55° and 4.25°; and cachexia incidence was 11.5% and 14.1%, respectively. The PhA cut-off in males with cachexia was 4.15°. Multivariate regression analysis showed that grip strength and brain natriuretic peptide (BNP) were independent determinants of SMI, whereas grip strength, BNP, and Hb were independent determinants of PhA. Thus, PhA appears to be a useful marker for sarcopenia, malnutrition, and cachexia in hospitalized patients with cardiovascular disease.

Abstract
Blood flow restriction (BFR) has the potential to augment muscle activation, which underlies strengthening and hypertrophic effects of exercise on skeletal muscle. We quantified the effects of BFR on muscle activation in the rectus femoris (RF), the vastus lateralis (VL), and the vastus medialis (VM) in concentric and eccentric contraction phases of low-intensity (10% and 20% of one repetition maximum) leg extension in seven cardiovascular patients who performed leg extension in four conditions: at 10% and 20% intensities with and without BFR. Each condition consisted of three sets of 30 trials with 30 s of rest between sets and 5 min of rest between conditions. Electromyographic activity (EMG) from RF, VL, and VM for 30 repetitions was divided into blocks of 10 trials and averaged for each block in each muscle. At 10% intensity, BFR increased EMG of all muscles across the three blocks in both concentric and eccentric contraction phases. At 20% intensity, EMG activity in response to BFR tended to not to increase further than what it was at 10% intensity. We concluded that very low 10% intensity exercise with BFR may maximize the benefits of BFR on muscle activation and minimize exercise burden on cardiovascular patients.

Abstract
We previously reported significant relationships between sialyl Lewis antigen expression on gastric cancer cells and both hepatic metastasis and clinical prognosis. The purpose of this study was to compare the expression of sialyl Lewis antigens on gastric cancer cells to elucidate the possible role of sialyl Lewis antigens in predicting the spread of a tumor with regard to histological findings. Subjects consisted of 38 patients with gastric cancer. For comparison we measured the values for sialyl Lewisa (sLea) and sialyl Lewisx (sLex) expression on the surface of about 10,000-30,000 cancer cells. Monoclonal antibodies CA19-9 and KM-93 were used to determine the frequency (%) and quantity (channel) of the expression by flow cytometry. We assessed the correlation of sLea and sLex expression with histological findings (depth of tumor invasion (pT), lymphatic invasion (ly), venous invasion (v), and lymph node metastasis (pN)), by comparing sLea and sLex expression in relation to the grade of histological findings. A significant relationship was found between lymphatic invasion and the frequency of sLea expression (r = 0.40, p<0.05). The mean values of sLea frequency in cases categorized as ly 2 (36.30) and ly 3 (31.81) were statistically higher than those in ly 1 cases (12.74) (p<0.05). A significant relationship was also observed between lymph node metastasis and the frequency of sLea expression (r = 0.46, p<0.01). The mean value of sLea frequency in pN 3 cases (44.14) was statistically higher than those in pN 0 (17.11) and pN 1 (19.03) cases (p<0.05). Neither the depth of tumor invasion nor venous invasion showed any correlation with the expression of sialyl Lewis antigens. In conclusion the frequency of sLea expression on the surface of gastric cancer cells was greater in those patients who developed lymphatic invasion and lymph node metastasis. However, the mechanism by which sialyl Lewisa expression is upregulated remains unclear.

Abstract
The patient was a 46-year-old women who was treated for axillary lymph node recurrence of breast cancer by a variety of methods, including surgery, chemotherapy, and radiotherapy, but who experienced recurrences in the cervical and mediastinal lymph nodes and skin, and developed hydrothorax and ascites. Although the recurrent foci responded to 4 cycles of CAF chemotherapy, there was concern that the foci would become refractory or resistant to chemotherapy. The administration of paclitaxel was therefore initiated. The patient received a dose of paclitaxel once a week for 5 consecutive weeks followed by a 1-week recovery period (one cycle). After two cycles of the paclitaxel treatment, a marked shrinkage of the lymph nodes and complete resolution of the hydrothorax and ascites were observed. Even though the patient exhibited bone marrow suppression and G-CSF was administered twice for neutropenia, there were no adverse effects except mild alopecia, again suggesting the possibility that paclitaxel is effective chemotherapy for recurrent breast cancer.

Abstract
Ten patients with liver metastases from advanced gastric cancer received percutaneous ethanol injection therapy (PEI) and chemotherapy by hepatic arterial infusion (HAI) via implantable reservoir. A 90% ethanol solution including 10%. Lipiodol was injected in the liver as PEI.5-FU, EPIR and MMC were used as the regimen for HAI chemotherapy. We have performed this therapy (PEI + HAI) for ten patients with liver metastases since February, 1997. These patients have received this therapy for 4-36 months and three patients died within 16 months. However, three patients did not develop any liver failure after this therapy. The median survival rate was 25.2 months. There are statistically significant differences between upto ss and over se of invasion, and between INF alpha and gamma (p = 0.005).

Abstract
We reported that a cell surface thrombin receptor, thrombomodulin (TM), was regulated by cyclic AMP in fibroblasts and in parietal endoderm-like cells derived from F9 embryonal carcinoma cells. In this paper, the genetic basis for augmentation of TM expression by cyclic AMP was studied in F9 and BALB/3T3 cells. Transient expression assays were performed with plasmid constructs containing various 5' flanking sequences of the TM gene and a reporter gene, chloramphenicol acetyltransferase (CAT). Two regulatory DNA regions, the proximal (-411 to -50) and the distal (-1026 to -850), were located. Interplay of the two regions was suggested using a heterologous thymidine kinase promoter in differentiated F9 cells. Both proximal and distal regions contributed to cyclic AMP-dependent augmentation of CAT expression in differentiated F9 cells, whereas only the proximal region was functional in BALB/3T3 cells. The two cell types responded differently also to a protein synthesis inhibitor, cycloheximide, with respect to TM message accumulation. In BALB/3T3 cells TM message accumulation was refractory to the inhibitor in contrast to that of differentiated F9 cells, which was only partially so. We propose that there are at least two separate genomic DNA regions that regulate cyclic AMP-dependent TM gene expression and that their functions are cell type dependent.

Abstract
Fetomodulin (FM) was previously shown to be a surface marker protein of parietal endoderm by in vitro differentiation of F9 embryonal carcinoma cells and by immunohistochemistry of in vivo embryos. BALB/3T3 and sarcoma S180 cells of the mouse were also shown to possess a protein which was indistinguishable from FM by immunological and structural criteria. We now show by protein and DNA sequencing and by functional assays that FM is identical to thrombomodulin, an anticoagulant endothelial thrombin receptor. Partial amino acid sequences of FM from S180 cells suggested homology between FM and thrombomodulin. An FM cDNA fragment was obtained by screening an expression library, which was constructed with restricted BALB/3T3 cDNA, with polyclonal anti-FM antibody. Several longer cDNA clones were than isolated using this fragment as a probe. They elucidated a 3369-bp partial sequence which encompassed 93% of the coding sequence. The remaining structure was determined from a genomic DNA clone. The deduced FM structure proved to be identical to that of thrombomodulin of mouse lung. Affinity-purified FM of BALB/3T3 and differentiated F9 cells was as active as thrombomodulin of the lung in binding thrombin and also as an anticoagulant. Structural and functional identity of the two proteins was thus confirmed. During embryonic development, FM immunoreactivity is localized not only in vasculatures but also at sites of cell-to-cell contact, including lung bud and neural epithelium, which were not expected a priori to possess this endothelial surface protein. FM may be a multifunctional protein with unique roles in embryonic development.
