Abstract
PURPOSE We investigated whether twice-daily administration of a bilayer tablet formulation of tramadol (35% immediate-release [IR] and 65% sustained-release) is as effective as four-times-daily IR tramadol capsules for managing cancer pain. METHODS This randomized, double-blind, double-dummy, active-comparator, non-inferiority study enrolled opioid-naïve patients using non-steroidal anti-inflammatory drugs or acetaminophen (paracetamol) to manage cancer pain and self-reported pain (mean value over 3 days ≥ 25 mm on a 100-mm visual analog scale [VAS]). Patients were randomized to either bilayer tablets or IR capsules for 14 days. The starting dose was 100 mg/day and could be escalated to 300 mg/day. The primary endpoint was the change in VAS (averaged over 3 days) for pain at rest from baseline to end of treatment/discontinuation. RESULTS Overall, 251 patients were randomized. The baseline mean VAS at rest was 47.67 mm (range: 25.6-82.7 mm). In the full analysis set, the adjusted mean change in VAS was - 22.07 and - 19.08 mm in the bilayer tablet (n = 124) and IR capsule (n = 120) groups, respectively. The adjusted mean difference was - 2.99 mm (95% confidence interval [CI] - 7.96 to 1.99 mm). The upper 95% CI was less than the predefined non-inferiority margin of 7.5 mm. Other efficacy outcomes were similar in both groups. Adverse events were reported for 97/126 (77.0%) and 101/125 (80.8%) patients in the bilayer tablet and IR capsule groups, respectively. CONCLUSION Twice-daily administration of bilayer tramadol tablets was as effective as four-times-daily administration of IR capsules regarding the improvement in pain VAS, with comparable safety outcomes.

Abstract
Histiocytic sarcoma (HS) is a rare hematopoietic neoplasm. We report a patient with HS treated with induction chemotherapy followed by curative surgery. A 50-year-old man was referred to our hospital because of a retroperitoneal tumor. A computed tomography scan revealed a bulky retroperitoneal mass, infiltrating the surrounding organ. An excisional biopsy confirmed the diagnosis of HS. The tumor shrunk after multidrug chemotherapy. However, positron emission tomography showed uptake of fludeoxyglucose in the residual tumor. He underwent right nephrectomy to remove the tumor. Pathological examination showed complete response. Surgery combined with induction chemotherapy may be an effective way to manage HS.

Abstract
Adult-onset hemophagocytic lymphohistiocytosis (HLH) has features that are distinct from that of HLH in pediatric patients. The clinical records at the Japanese Red Cross Kumamoto Hospital were reviewed. We retrospectively analyzed 34 patients who fulfilled the diagnostic criteria of HLH-2004. The median age of patients was 60.0 (range 15-86). Underlying diseases were diagnosed in 17 patients. They consisted of malignant lymphoma (n=3), other neoplastic disease (n=3), viral infection (n=4), collagen vascular disease (n=3), Kikuchi’s disease (n=3) and drug (n=1). Underlying diseases were not diagnosed in 17 patients despite examination. The treatments were steroids (n=18), dexamethasone + cyclosporine A (CSA) + etoposide (n=4), multidrug chemotherapy (n=2), steroids and CSA (n=3). Eleven patients died during observation. In a multivariate analysis, the significant predictor for death was age at onset (hazard ratio, 1.22; 95%CI, 1.02-1.44; P=0.027). Autopsy was performed in 4 cases, but the underlying disease remained unknown in 3 of those cases. Adult-onset HLH has high diversity and various outcomes. The mechanism of adult-onset HLH is not fully understood and further research is required.

Abstract
Vascular-targeting antiangiogenic therapy (VTAT) of cancer can be advantageous over conventional tumor cell targeted cancer therapy if an appropriate target is found. Our hypothesis is that endoglin (ENG; CD105) is an excellent target in VTAT. ENG is selectively expressed on vascular and lymphatic endothelium in tumors. This allows us to target both tumor-associated vasculature and lymphatic vessels to suppress tumor growth and metastasis. ENG is essential for angiogenesis/vascular development and a co-receptor of TGF-β. Our studies of selected anti-ENG monoclonal antibodies (mAbs) in several animal models and in vitro studies support our hypothesis. These mAbs and/or their immunoconjugates (immunotoxins and radioimmunoconjugates) induced regression of preformed tumors as well as inhibited formation of new tumors. In addition, they suppressed metastasis. Several mechanisms were involved in the suppressive activity of the naked (unconjugated) anti-ENG mAbs. These include direct growth suppression of proliferating endothelial cells, induction of apoptosis, ADCC (antibody-dependent cell-mediated cytotoxicity) and induction of T cell immunity. To facilitate clinical application, we generated a human/mouse chimeric anti-ENG mAb termed c-SN6j and performed studies of pharmacokinetics, toxicology and immunogenicity of c-SN6j in nonhuman primates. No significant toxicity was detected by several criteria and minimal immune response to the murine part of c-SN6j was detected after multiple i.v. injections. The results support our hypothesis that c-SN6j can be safely administered in cancer patients. This hypothesis is supported by the ongoing phase 1 clinical trial of c-SN6j (also known as TRC105) in patients with advanced or metastatic solid cancer in collaboration with Tracon Pharma and several oncologists (NCT00582985).

Abstract
Anti-metastatic activity of an antitumor agent is exceedingly important because metastasis is the primary cause of death for most solid cancer patients. In this report, we show that 3 anti-endoglin (ENG) monoclonal antibodies (mAbs) SN6a, SN6j and SN6k which define individually distinct epitopes of ENG of tumor vasculature are capable of suppressing tumor metastases in the multiple metastasis models. The metastasis models were generated by i.v., s.c. (into flank) or mammary gland fat pad injection of 4T1 murine mammary carcinoma cells and splenic injection of two types of colon26 murine colorectal carcinoma cells. Individual mAbs were injected i.v. via the tail vein of mice. SN6a and SN6j effectively suppressed the formation of metastatic colonies of 4T1 in the lung in all of the three 4T1 metastatic models. In addition, these mAbs were effective for suppressing the primary tumors of 4T1 in the skin and mammary fat pad. These mAbs effectively suppressed microvessel density and angiogenesis in tumors as measured by the Matrigel plug assay in mice. No significant side effects of the administered mAbs were detected. Furthermore, SN6a and SN6j extended survival of the tumor-bearing mice. SN6j, SN6k and their immunoconjugates with deglycosylated ricin A-chain were all effective for suppressing hepatic metastasis of colon26. The findings in the present study are clinically relevant in view of the ongoing clinical trial of a humanized (chimerized) form of SN6j.

Abstract
In the present study, we investigated the mechanisms by which anti-endoglin (EDG; CD105) monoclonal antibodies (mAbs) suppress angiogenesis and tumor growth. Antihuman EDG mAb SN6j specifically bound to murine endothelial cells and was internalized into the cells in vitro. SN6j effectively suppressed angiogenesis in mice in the Matrigel plug assay. We found that SN6j is more effective for tumor suppression in immunocompetent mice than in SCID mice. We hypothesized that T cell immunity is important for effective antitumor efficacy of SN6j in vivo. To test this hypothesis, we investigated effects of CpG oligodeoxynucleotides (ODN) and depletion of CD4(+) T cells and/or CD8(+) T cells on antitumor efficacy of SN6j in mice. Systemic (i.v.) administration of a relatively small dose (0.6 mug/g body weight/dose) of SN6j suppressed growth of established s.c. tumors of colon-26 in BALB/c mice and improved survival of the tumor-bearing mice. Addition of CpG ODN to SN6j synergistically enhanced antitumor efficacy of SN6j. In contrast, such enhancing effects of CpG ODN were not detected in SCID mice. Antitumor efficacy of SN6j in BALB/c mice was abrogated when CD4(+) T cells and/or CD8(+) T cells were depleted; effect of CD8(+) T cell depletion was stronger. Interestingly, CD4-depletion decreased tumor growth while CD8-depletion enhanced tumor growth in the absence of SN6j. SN6j induced apoptosis in human umbilical vein endothelial cells in a dose-dependent manner which indicates an additional mechanism of antiangiogenesis by SN6j. (c) 2008 Wiley-Liss, Inc.

Abstract
We investigated anti-angiogenic/vascular targeting therapy of established tumors in immunocompetent mice using an anti-human endoglin (EDG; CD105) monoclonal antibody (mAb) SN6j. SN6j weakly cross-reacted with murine endothelial cells but reacted neither with colon-26 murine colon carcinoma cells nor with 4T1 murine mammary carcinoma cells. Systemic administration of naked (unconjugated) SN6j showed significant growth suppression of established tumors of colon-26 and 4T1 cells in immunocompetent BALB/c mice (P<0.05). Moreover, the overall survival rate of SN6j-treated mice was significantly higher than that of control IgG-treated mice (P<0.01). During these studies, we found that two different types of tumor formed in BALB/c and immunodeficient SCID mice when three different types of tumor cells (colon-26, 4T1 and MCF-7 human breast cancer cells) were inoculated subcutaneously. One type of tumor grew in the skin-side tissue (i.e., epidermis, corium, or subcutis), and mainly invaded into the corium and epidermis. The other type grew in the muscle-side tissue (i.e., fascia, muscle, or peritoneum/pleura). We termed the former SS tumors and the latter MS tumors. MS tumors grew faster than SS tumors. This differential growth of MS and SS tumors was observed in three different animal models, i.e., colon-26 tumors and 4T1 tumors in BALB/c mice, and MCF-7 tumors in SCID mice. In the therapeutic study of colon-26 and 4T1 tumors with SN6j, MS tumors were less responsive to therapy than SS tumors although SN6j showed significant antitumor efficacy against both tumors (P<0.05). The results show that antitumor therapy can yield different therapeutic outcomes depending on the tumor growth sites even for the same tumor. A differential survival between mice with the two types of tumor was also observed when mice were untreated (P<0.01).

Abstract
The endoplasmic reticulum (ER) is an organelle in which proteins are modified. When unfolded proteins accumulate in the ER under various stresses, ER stress (ERS) pathways, including the induction of chaperones, are activated to protect the cell. However, when ERS is excessive, the cell undergoes apoptosis. This study investigated ERS in multiple myeloma cells (MMCs) because they contain a well-developed ER due to M-protein production. The myeloma cell line 12-PE underwent apoptosis via caspase-3 after treatment with thapsigargin (thap), an ERS inducer, while another cell line, U266, did not. To understand the mechanism regulating this heterogeneity, the induction of chaperones by thap was analysed. Chaperones were up-regulated in U266 cells but down-regulated in 12-PE cells, suggesting that chaperones contribute to cell survival under ERS. Analysis of XBP-1, a transcriptional inducer of chaperones, in freshly isolated MMCs from 22 myeloma cases revealed 10 cases with active XBP-1, who also showed significantly poorer survival (p < 0.05), suggesting that chaperone expression protects MMCs from apoptosis, thereby allowing tumor cell expansion. These results suggest that MMCs are subjected to ERS under certain circumstances and that chaperones are induced to protect the cells against such ERS. Inhibition of chaperones could be a new target for myeloma therapy.

Abstract
We generated a human/mouse chimeric antibody c-SN6j of human IgG1 isotype from a murine anti-human endoglin (EDG) monoclonal antibody (mAb) SN6j that suppressed angiogenesis, tumor growth and metastasis in mice. We determined pharmacokinetics (PKs) and immunogenicity of c-SN6j in monkeys after multiple i.v. injections. A dose-escalation study was performed by administration of c-SN6j into six monkeys at the dose of 1 mg, 3 mg and 10 mg per kg body weight. In addition, both c-SN6j (3 mg/kg) and doxorubicin (0.275 mg/kg) were injected into two monkeys. c-SN6j and doxorubicin were injected twice a week for 3 weeks. We developed a unique and sensitive ELISA by sequentially targeting the common and idiotypic epitopes of c-SN6j-Fv to quantify plasma c-SN6j. Application of the ELISA showed that increasing the c-SN6j dose resulted in a proportional increase in the circulating c-SN6j after the first injection. In addition, the estimated area under the curve (AUC) for the first injection of c-SN6j is proportional to dose. We carried out detailed analyses of PKs of c-SN6j during and after the repeated injections. Our model of PKs fitted the empirical data well. Addition of doxorubicin modulated the PK parameters. We developed two ELISAs to separately determine the immune responses to the murine part and the human part of c-SN6j in monkeys. Interestingly, the murine part induced a weaker immune response than the human part. Doxorubicin potentiated the immune responses. Increasing the dose of c-SN6j increased plasma levels of c-SN6j but did not increase the immune responses to c-SN6j.

Abstract
Nuclear factor-kappaB (NF-kappaB) is constitutively activated in multiple myeloma cells. Several proteasome inhibitors have been shown to be effective against multiple myeloma and may act by inhibiting degradation of IkappaBalpha. Here, we examined the biological effects of a new type of NF-kappaB inhibitor, dehydroxymethylepoxyquinomicin (DHMEQ), which is reported to directly inhibit the cytoplasm-to-nucleus translocation of NF-kappaB. A multiple myeloma cell line, 12PE, which is defective for IkappaBalpha protein, was utilized to determine if IkappaBalpha is concerned with the action of DHMEQ. Meanwhile, U266 was used as a multiple myeloma cell line with normal IkappaBalpha. A proteasome inhibitor, gliotoxin, which is an inhibitor of degradation of phosphorylated IkappaBalpha, failed to inhibit translocation of NF-kappaB in 12PE. In contrast, DHMEQ equally inhibited translocation of NF-kappaB to the nucleus and induced apoptosis to both multiple myeloma cell lines, suggesting that apoptosis resulting from DHMEQ is IkappaBalpha independent. DHMEQ also induced apoptosis in freshly isolated multiple myeloma cells. After DHMEQ treatment, cleavage of caspase-3 and down-regulation of cyclin D1 were observed in both cell lines. In addition, administration of DHMEQ resulted in a significant reduction in tumor volume in a plasmacytoma mice model compared with control mice. Our results show that DHMEQ could potentially be a new type of molecular target agent for multiple myeloma.

Abstract
Angiogenesis is one of critical factors in sustaining the growth, invasion and metastasis of certain solid tumours and haematological malignancies such as multiple myeloma (MM). In the present study, we examined the anticancer potential of an inhibitor of nitric oxide synthase (NOS), NG-nitro-l-arginine methyl ester (L-NAME), in a novel severe combined immunodeficient mouse model (KHM mouse) that harbours the highly sanguineous plasmacytoma cell line KHM-4, derived from a patient with highly chemoresistant MM. KHM mice were intraperitoneally administered with either L-NAME, doxorubicin, melphalan, or paclitaxel. A significant reduction in tumour sizes was noted in L-NAME-administered KHM mice while no significant reduction was observed in melphalan- or doxorubicin-administered mice. A profound decrease in angiogenesis was observed in tumour tissues from L-NAME- and paclitaxel-administered KHM mice. A marked decrease in human vascular endothelial cell growth factor (VEGF) levels was identified in tumour tissues from L-NAME-administered KHM mice, strongly suggesting that L-NAME suppressed VEGF production by tumour cells through its inhibition of NOS in tumour cells, resulting in reduced neovasculization in mice leading to the regression of tumour sizes. The present data represent the first observations that certain NOS inhibitors potentially serve as experimental agents for the treatment of chemoresistant MM and plasmacytoma.

Abstract
Macrophage inflammatory protein-1 alpha (MIP-1alpha) is a chemokine primarily associated with bone absorption. We examined whether MIP-1alpha was produced by purified fresh tumour cells isolated from bone marrow samples from 31 multiple myeloma (MM) patients. High levels of MIP-1alpha were found in supernatants of myeloma cell cultures. Immunohistochemical staining showed MIP-1alpha in the cytoplasm of myeloma cells. MIP-1alpha mRNA expression was detected in 18 of 31 patients. Bone lesions were seen in 16 of the 18 MIP-1alpha-positive patients but only in six of the 13 MIP-1alpha-negative patients (P = 0.0097,chi2-test). The data indicate that MIP-1alpha is produced by myeloma cells and possibly plays a role in the pathogenesis of bone lesions in MM patients.

Abstract
The relationships between angiotensin-converting enzyme (ACE) gene insertion (I) / deletion (D) polymorphism and left ventricular hypertrophy induced by hypertension or idiopathic hypertrophic cardiomyopathy have been studied. However, little is known about the association between this polymorphism and left ventricular hypertrophy induced by volume overload. The relationship between left ventricular hypertrophy and the ACE gene I/D polymorphism was examined in 80 maintenance hemodialysis patients (mean age: 60.1+/-1.4 <SEM> years). Multivariate regression analysis showed that the left ventricular mass index calculated by M-mode echocardiography was associated with serum creatinine (p = 0.040), male gender (p = 0.027), antihypertensive drug treatment (p = 0.026), weight gain between hemodialysis (p = 0.018) and mean blood pressure after hemodialysis (p=0.010), but not with ACE I/D genotype (p = 0.69). These findings suggest that although hemodialysis patients seem to be under volume overload, ACE genotype may not be involved in their left ventricular hypertrophy. Hypertension and other factors related to renal failure are involved in the left ventricular hypertrophy in chronic hemodialysis patients.

Abstract
To determine whether there may be an abnormality in sympathetic nerve activity in response to physical and psychological stressors, we microneurologically recorded muscle sympathetic nerve activity in 11 normotensive and 9 borderline hypertensive, age-matched men. Supine blood pressure, plasma levels of epinephrine and norepinephrine and muscle sympathetic nerve activity were measured before and during a cold pressor test or a mental arithmetic test. The resting basal values of muscle sympathetic nerve activity, blood pressure and plasma epinephrine were significantly higher in the borderline hypertensives than in the normotensives (P less than 0.05). Plasma norepinephrine levels tended to be higher in the borderline hypertensives than in the normotensives but not to a significant extent (P less than 0.10). The cold test produced significantly exaggerated pressor and muscle sympathetic nerve responses (P less than 0.05) with a trend towards an increase in plasma norepinephrine (P less than 0.10) in the borderline hypertensives as compared with normotensives. The mental arithmetic test produced significantly enhanced pressor and plasma epinephrine responses in the borderline hypertensives as compared with the normotensives (P less than 0.05). During the mental arithmetic test the muscle sympathetic nerve activity decreased significantly in the normotensives (P less than 0.05) but not in the borderline hypertensives. These findings indicate that in people with borderline hypertension an abnormality exists in sympathetic nerve activity at rest and in response to stressors.

Abstract
Effects of captopril on arterial pressure (AP) and renal function were investigated in patients with non-malignant "benign" or malignant phase essential hypertension (EH group), or with chronic renal failure (CRF group). After captopril administration, AP and renal vascular resistance (RVR) decreased significantly, and renal blood flow (RBF) and plasma renin activity (PRA) increased in both groups. Glomerular filtration rate (GFR) increased in the EH group, but was unchanged in CRF. Filtration fraction decreased in the malignant hypertension and CRF groups. Significant correlations were found between baseline PRA and baseline RVR, and the captopril-induced decrease in mean AP, decrease in RVR, increase in RBF, and increase in GFR in the EH group, while these associations were not observed in CRF. These results indicate that the high AP, RVR, suppressed RBF and GFR in the EH group were closely related to activity of the renin-angiotensin system, but not so the low RBF and GFR in CRF. Small doses of captopril may improve impaired renal function in EH, and may not cause deterioration in the CRF group.

Abstract
The antihypertensive effect of a non-sulfhydryl, long acting ACE (angiotensin converting enzyme) inhibitor, MK-421, was evaluated by administering a single dose of 10 mg to 13 patients with mild to moderate essential hypertension. The pharmacokinetic profile of MK-421 and its potent active metabolite, MK-422, was also assessed, together with the effect on the various components of the renin-angiotensin system. A single dose of MK-421 produced a significant fall in MBP from 2 to 24 hours post-drug. As could be expected, plasma ACE activity was suppressed up to 24 hours after MK-421. The half-life of MK-422, Cmax and [AUC]24(0) of MK-421 and MK-422 were measured. No significant change in plasma bradykinin or urinary excretion rate of kallikrein was observed, whereas a slight increase was observed in the urinary excretion rate of kinins after MK-421 in 8 patients. Significant correlations were observed between pretreatment PRA levels and the maximum fall in MBP.

Abstract
Relationships between renal haemodynamics and the renin-angiotensin system were examined in 128 male adolescents with differing predispositions to hypertension. Baseline renal vascular resistance (RVR) was significantly elevated in the normotensive subjects with a positive family history, NT (FH+) group, than in the normotensives with a negative family history, NT (FH-) group, while there were no significant differences in other characteristics between the two groups. The borderline hypertensive subjects with a positive family history, BH (FH+) group, showed an even bigger increase in RVR and also had elevated plasma renin activity (PRA). In the NT (FH+) and BH (FH+) groups RVR correlated significantly with PRA levels. When captopril was given, the increased RVR in the NT (FH+) and BH (FH+) groups decreased, in correlation with baseline PRA, to levels not significantly different from those in the NT (FH-) group, in which no significant changes occurred in RVR. These results suggest that RVR may increase primarily in adolescents genetically predisposed to essential hypertension and that the renin-angiotensin system may play an important role in the mechanism of this increase in RVR.

Abstract
To simplify 24-hour urine collection for epidemiological and clinical examinations, we devised a portable, semiautomatic urine sampling cup with divided partitions. The cup, 6.6 cm in diameter and 14 cm in height, is double-bottomed and has a pipe-shaped scale and a cock leading to the lower compartment. It is so devised that 1/m of the urine volume excreted into the upper compartment each time remains in the pipe scale, and then comes down into the lower compartment by manipulating the cock. The urine in the lower compartment remains when the urine in the upper compartment is discarded. The cup is carried in a vinyl bag. By repeating this manipulation. 1/m of the total urine excreted during 24 hours can be collected in the small cup (proportional sampling method). When the 24-hour urinary sodium excretion measured by the conventional method and that measured by this method were compared, the correlation coefficient (r) was 0.98, and the average variation was 2.0 +/- 10.8 (SD) mEq (n = 32). Use of this device for outpatients was convenient and enabled counseling on salt intake.

Abstract
ECF (extracellular fluid volume) was measured by 35S-sodium sulfate and the same time value of PV (plasma volume) was determined by 131I-RISA in each subject. In normal ECF was an average of 181 ml/kg, 6.21 l/m2 and PV was 49.1 ml/kg, 1.69 l/m2. Both values of ECF and PV in essential hypertension were almost the same as those in normal. In congestive heart failure ECF was 232 ml/kg, 7.51 l/m2 and PV was 55.8 ml/kg, 1.80 l/m2. In the patients with ascites or edema, ECF was 256 ml/kg, 8.69 l/m2 and PV was 53.0 ml/kg, 1.79 l/m2. The results of the measurement by the two compounds also corresponded to the conditions of the patients who showed electrolytes disorders (ACTH deficiency, SIADH) and was improved by treatment.
