Abstract
INTRODUCTION There is limited evidence on the costs and outcomes of patients with aphasia after stroke. The aim of this study was to estimate costs in patients with aphasia after stroke according to the aphasia therapies provided. METHODS A three-arm, prospective, randomized, parallel group, open-label, blinded endpoint assessment trial conducted in Australia and New Zealand. Usual ward-based care (Usual Care) was compared to additional usual ward-based therapy (Usual Care Plus) and a prescribed and structured aphasia therapy program in addition to Usual Care (the VERSE intervention). Information about healthcare utilization and productivity were collected to estimate costs in Australian dollars for 2017-18. Multivariable regression models with bootstrapping were used to estimate differences in costs and outcomes (clinically meaningful change in aphasia severity measured by the WAB-R-AQ). RESULTS Overall, 202/246 (82%) participants completed follow-up at 26 weeks. Median costs per person were $23,322 (Q1 5,367, Q3 52,669, n = 63) for Usual Care, $26,923 (Q1 7,303, Q3 76,174, n = 70) for Usual Care Plus and $31,143 (Q1 7,001. Q3 62,390, n = 69) for VERSE. No differences in costs and outcomes were detected between groups. Usual Care Plus was inferior (i.e. more costly and less effective) in 64% of iterations, and in 18% was less costly and less effective compared to Usual Care. VERSE was inferior in 65% of samples and less costly and less effective in 12% compared to Usual Care. CONCLUSION There was limited evidence that additional intensively delivered aphasia therapy within the context of usual acute care provided was worthwhile in terms of costs for the outcomes gained.

Abstract
BACKGROUND Optimising blood pressure (BP) control is one of the most important modifiable risk factors in preventing subsequent stroke where the risk increases by one-third for every 10 mmHg rise in systolic BP. This study evaluated the feasibility and potential effectiveness of blood pressure self-monitoring with planned medication titration, to inform a definitive trial of the intervention, in patients with a previous stroke or transient ischaemic attack (TIA). METHODS Patients with a history of stroke/TIA and sub-optimal BP control were invited to take part in a mixed methods feasibility study for a randomised controlled trial. Those meeting the inclusion criteria with systolic BP >130 mmHg were randomised to a self-monitoring intervention group or usual care group. The intervention involved self-monitoring BP twice a day for 3 days within a 7-day period, every month, following text message reminders. Treatment escalation, based on a pre-agreed plan by the general practitioner (GP) and patient, was initiated according to the results of these readings. Semi-structured interviews were carried out with patients and clinicians and analysed thematically. RESULTS Of those identified, 47% (32/68) attended for assessment. Of those assessed, 15 were eligible for recruitment and were consented and randomised to the intervention or control group on a 2:1 basis. Of those randomised, 93% (14/15) completed the study and there were no adverse events. Systolic BP was lower in the intervention group at 3 months. Participants found the intervention acceptable and easy to use. GPs found it easy to incorporate into their practice activity without increasing workload. CONCLUSIONS TASMIN5S, an integrated blood pressure self-monitoring intervention in patients with a previous stroke/TIA, is feasible and safe to deliver in primary care. A pre-agreed three-step medication titration plan was easily implemented, increased patient involvement in their care, and had no adverse effects. This feasibility study provides important information to inform a definitive trial to determine the potential effectiveness of the intervention in patients post-stroke or TIA. TRIAL REGISTRATION ISRCTN57946500 . Registered on 12/08/2019.

Abstract
Cryotherapy has been used as salvage therapy; however, its efficacy as first line treatment in patients with Barrett's esophagus (BE) neoplasia has not been well studied. The aim of this paper was to perform a systematic review to look at the efficacy of cryotherapy as the primary treatment of BE. An electronic database search was performed (PubMed, Embase, Cochrane, and Google Scholar) to search for studies with cryotherapy as the initial primary modality of ablation in patients with BE neoplasia. Studies that included patients with other prior forms of therapy were excluded. The primary outcomes were the pooled rates of complete eradication of intestinal metaplasia (CE-IM) and CE of neoplasia (CE-N). Secondary outcomes were recurrence rates of neoplasia and intestinal metaplasia (IM) and adverse events. The statistical software OpenMetaAnalyst was used for analysis with pooled estimates reported as proportions (%) with 95% confidence intervals (CI) with heterogeneity (I2) among studies. The search revealed 6 eligible studies with a total of 282 patients (91.5% male, average age 65.3 years) with 459 person years of follow-up. 69.35% [95% CI (52.1%-86.5%)] of patients achieved CE-IM and 97.9% (95% CI: 95.5%-100%) had CE-N. 7.3% of patients had persistent dysplasia with 4% progressing to cancer. The recurrence rate of neoplasia was 10.4 and that of IM was 19.1 per 100 patient years of follow-up. The overall rate of stricture formation was 4.9%. There are scarce data on the use of cryotherapy as the primary modality for the treatment of BE dysplasia. The published data demonstrate efficacy rates of 69% and 98% for complete eradication of metaplasia and neoplasia, respectively. These results need to be assessed in prospective, comparative trials with other forms of therapy.

Abstract
Distinguishing autosomal-dominant polycystic kidney disease (ADPKD) from other inherited renal cystic diseases in patients with adult polycystic kidney disease and no family history is critical for correct treatment and appropriate genetic counseling. However, for patients with no family history, there are no definitive imaging findings that provide an unequivocal ADPKD diagnosis. We analyzed 53 adult polycystic kidney disease patients with no family history. Comprehensive genetic testing was performed using capture-based next-generation sequencing for 69 genes currently known to cause hereditary renal cystic diseases including ADPKD. Through our analysis, 32 patients had PKD1 or PKD2 mutations. Additionally, 3 patients with disease-causing mutations in NPHP4, PKHD1, and OFD1 were diagnosed with an inherited renal cystic disease other than ADPKD. In patients with PKD1 or PKD2 mutations, the prevalence of polycystic liver disease, defined as more than 20 liver cysts, was significantly higher (71.9% vs 33.3%, P = .006), total kidney volume was significantly increased (median, 1580.7 mL vs 791.0 mL, P = .027) and mean arterial pressure was significantly higher (median, 98 mm Hg vs 91 mm Hg, P = .012). The genetic screening approach and clinical features described here are potentially beneficial for optimal management of adult sporadic polycystic kidney disease patients.

Abstract
BACKGROUND It is unclear whether more timely cancer diagnosis brings favourable outcomes, with much of the previous evidence, in some cancers, being equivocal. We set out to determine whether there is an association between time to diagnosis, treatment and clinical outcomes, across all cancers for symptomatic presentations. METHODS Systematic review of the literature and narrative synthesis. RESULTS We included 177 articles reporting 209 studies. These studies varied in study design, the time intervals assessed and the outcomes reported. Study quality was variable, with a small number of higher-quality studies. Heterogeneity precluded definitive findings. The cancers with more reports of an association between shorter times to diagnosis and more favourable outcomes were breast, colorectal, head and neck, testicular and melanoma. CONCLUSIONS This is the first review encompassing many cancer types, and we have demonstrated those cancers in which more evidence of an association between shorter times to diagnosis and more favourable outcomes exists, and where it is lacking. We believe that it is reasonable to assume that efforts to expedite the diagnosis of symptomatic cancer are likely to have benefits for patients in terms of improved survival, earlier-stage diagnosis and improved quality of life, although these benefits vary between cancers.

Abstract
Background The purpose of this open-label study was to correlate the auscultation findings of ZargisCardioscan™ with the echocardiographic findings in our patient population who were referred for echocardiography so as to investigate and ensure the validity of this technology before instituting its applicability in community health events among rural Indian population. Materials and Methods This was a double blinded prospective correlation study in outpatients presenting for echocardiography. Methods: One hundred patients, who had presented for echocardiography at Cardiology Center of an academic university hospital in rural India, were enrolled in this double blinded prospective correlation study. Principal investigator who is a community medicine physician performed the auscultation of patients’ hearts in sitting position. Subsequently, the ZargisCardioscan™ software was used to analyze the heart sounds auscultated by the 3M™ Littmann® Model 3200 stethoscope. Thereafter, the scheduled echocardiography for which the patient had presented to hospital was performed by co-investigator cardiologist who was blinded to the results obtained by the ZargisCardioscan™.Finally, all these data were statistically analyzed by blinded investigator for the presence of correlation between the two modalities. Results The most important finding was the high 90s negative predictive values when the stethoscope-software combination was used for auscultation and analysis of heart murmurs. Additionally, presence of isolated systolic murmurs had higher incidence of appreciable significant valvular lesions and presence of isolated diastolic murmurs primarily had underlying minimal-mild regurgitant valvular lesion, if any. The Bland-Altman Plot confirmed good correlation between stethoscope-echocardiography findings. Conclusion Stethoscope-software combination, 3M™ Littmann® Model 3200 and ZargisCardioscan™, accurately predicts the absence of valvular heart disease on echocardiography.DOI: http://dx.doi.org/10.3126/nje.v4i3.10665 Nepal Journal of Epidemiology 2014; 4(3): 363-369

Abstract
BACKGROUND Multimarker quantitative real-time polymerase chain reaction (qRT-PCR) represents an effective method for detecting circulating tumour cells in the peripheral blood of patients with melanoma. OBJECTIVES To investigate whether the phenotype of circulating melanoma cells represents a useful indicator of disease stage, recurrence and treatment efficacy. METHODS Peripheral blood was collected from 230 patients with melanoma and 152 healthy controls over a period of 3years and 9months. Clinical data and blood samples were collected from patients with primary melanoma (early stages, 0-II, n=154) and metastatic melanoma (late stages, III-IV, n=76). Each specimen was examined by qRT-PCR analysis for the expression of five markers: MLANA, ABCB5, TGFβ2, PAX3d and MCAM. RESULTS In total, 212 of the patients with melanoma (92%) expressed markers in their peripheral blood. Two markers, MLANA and ABCB5, had the greatest prognostic value, and were identified as statistically significant among patients who experienced disease recurrence within our study period, being expressed in 45% (MLANA) and 49% (ABCB5) of patients with recurrence (P=0·001 and P=0·031, respectively). For patients administered nonsurgical treatments, MCAM expression correlated with poor treatment outcome. CONCLUSIONS Circulating tumour cells were detectable at all stages of disease and long after surgical treatment, even when patients were considered disease free. Specifically, expression of ABCB5 and MLANA had significant prognostic value in inferring disease recurrence, while MCAM expression was associated with poor patient outcome after treatment, confirming multimarker qRT-PCR as a potential technique for monitoring disease status.

Abstract
The authors present a polymerase chain reaction method for rapid and direct diagnosis of herpetic intraocular infections using small volume samples of intraocular fluid from 29 patients with various intraocular inflammatory diseases and 24 controls with senile cataract. Of six patients with early acute retinal necrosis from whom aqueous humor was tested, four were found to be positive for the presence of varicella-zoster (VZV) DNA while the other two were positive for the presence of herpes simplex virus (HSV) DNA. One of the patients with HSV DNA had been tested at an extremely early stage, at which time the aqueous humor viral antibody ratio did not predict a specific viral infection. Among four patients with acute retinal necrosis in relatively late stages following treatment with acyclovir from whom vitreous was obtained and tested, only one was found to have the presence of any viral DNA (VZV). On the other hand, the vitreous viral antibody ratio was found to be predictive of VZV infection in all four cases. VZV DNA was also detected in aqueous humor samples from four patients with suspected herpes zoster anterior uveitis, while HSV DNA was found in the aqueous humor of one patient with nonspecific keratouveitis. Neither human cytomegalovirus DNA nor human herpesvirus-6 DNA was detected in any sample included in this study. Finally, Epstein-Barr virus DNA was detected in the aqueous humor of the majority of patients studied and identified in cataract patients as well, suggesting either low specificity of the authors' assay for this virus or ubiquity of this virus in human eyes. In summary, the PCR method proved to be a very useful tool in establishing an etiological diagnosis in patients in the early stages of acute retinal necrosis, and in patients with anterior uveitis due to suspected HSV or VZV infection.

Abstract
Melanoma differentiation-associated gene-5 (mda-5) was the first molecule identified in nature whose encoded protein embodied the unique structural combination of an N-terminal caspase recruitment domain and a C-terminal DExD/H RNA helicase domain. As suggested by its structure, cumulative evidences documented that ectopic expression of mda-5 leads to growth inhibition and/or apoptosis in various cell lines. However, the signaling pathways involved in mda-5-mediated killing have not been elucidated. In this study, we utilized either genetically modified cloned rat embryo fibroblast cells overexpressing different functionally and structurally distinct oncogenes or human pancreatic and colorectal carcinoma cells containing mutant active ras to resolve the role of the Ras/Raf signaling pathway in mda-5-mediated growth inhibition/apoptosis induction. Rodent and human tumor cells containing constitutively activated Raf/Raf/MEK/ERK pathways were resistant to mda-5-induced killing and this protection was antagonized by intervening in this signal transduction cascade either by directly inhibiting ras activity using an antisense strategy or by targeting ras-downstream factors, such as MEK1/2, with the pharmacological inhibitor PD98059. The present findings provide a further example of potential cross-talk between growth-inhibitory and growth-promoting pathways in which the ultimate balance of these factors defines cellular homeostasis, leading to survival or induction of programmed cell death.

Abstract
We report a case involving leakage of cyanoacrylate (CA) to the inferior vena cava (IVC) through a gastrorenal shunt and left renal vein. A 72-year-old man with liver cirrhosis was admitted to our hospital to undergo emergency treatment for massive hemorrhage of gastric varices. Endoscopic injection sclerotherapy (EIS) using CA was performed on the varices. Radiographic fluoroscopy revealed that most of the injected CA had adhered firmly to the gastric varices, but a certain portion of the CA had flowed to the IVC through the gastrorenal shunt and left renal vein. At that point, the patient did not complain of any symptoms. However, 6 months later, he died of hepatic failure and an autopsy was performed. Histopathologic examination of the wall of the IVC and renal vein, to which CA had adhered, revealed that the CA was covered with endothelial cells of the vessel and no nearby thrombus was present. Long-term anticoagulant therapy may not be indicated in cases of leakage of CA from the gastric varices to other veins, since the leaked CA may be readily covered with endothelium without thrombus formation as in our patient. It is possible for CA to flow to the IVC and have a fatal impact. Our patient was fortunate, and for safe EIS it is important that these complications are prevented.

Abstract
CLC-K1 and CLC-K2 are highly homologous kidney-specific chloride channels, but they are expressed in the different nephron segments. To understand the molecular mechanisms of kidney-specific and nephron-segment-specific expression of CLC-K channel genes, the rat ClC-K2 gene promoter was cloned and compared with that of CLC-K1. In the 1.5-kb pair 5'-flanking region of the CLC-K2 gene, no TATA box was identified around the transcriptional start site, and the proximal region (-32 to -68) was characterized by a GA-rich motif that had a significant sequence similarity to that of the previously isolated CLC-K1 gene promoter. In contrast, the distal portion did not have significant sequence similarity to that of CLC-K1. Reporter gene assay and gel-retardation analysis revealed that the GA-rich motif and the binding of a specific protein(s) to this element were indispensable for the basal promoter activity of the CLC-K2 gene. These results suggest that the GA-rich element may have an important role in the promoter activities of the kidney-specific CLC-K1 and -K2 genes, but that the GA-element alone is not sufficient for the strict regulation of nephron-segment-specific expression of CLC-K1 and CLC-K2 genes.

Abstract
The rat ClC-K1 chloride channel is a kidney-specific member of the ClC chloride channel family found exclusively in the thin ascending limb of Henle's loop in the kidney. To gain insight into the mechanism(s) of kidney-specific expression of ClC-K1, a genomic clone that contains the 5'-flanking region of the rat ClC-K1 gene was isolated. A single transcription start site was located 84 bp upstream of the start codon. The sequence of the proximal 5'-flanking region contained an activator protein (AP)-3 site, a glucocorticoid-responsive element, several AP-2 sites, and several E-boxes, but it lacked a TATA box. To functionally express the promoter, the approximately 2.5-kb pair 5'-flanking region was ligated to a luciferase reporter gene and transfected into inner medullary (IM) cells, a stable ClC-K1-expressing cell line derived from the inner medulla of simian virus 40 transgenic mouse, and ClC-K1-nonexpressing cell lines. Luciferase activity was 7-to 24-fold greater in IM cells than those in nonexpressing cell lines, suggesting that the approximately 2.5-kb fragment contained cis-acting regulatory elements for cell-specific expression of the ClC-K1 gene. Deletion analysis revealed that this cell-specific promoter activity in IM cells was still present in the construct containing 51 bp of the 5'-flanking region but was lost in the -29 construct, clearly demonstrating that the 22 bp from -51 to -30 have a major role in the cell-specific activity of the ClC-K1 promoter. These 22 bp consist of purine-rich sequence (GGGGAGGGG-GAGGGGAG), and gel-retardation analysis demonstrated the existence of a specific protein(s) binding to this element in IM cells. These results suggest that the novel purine-rich element may play a key role in the activity of the ClC-K1 gene promoter.

Abstract
Since phosphorus retention in hemodialysis (HD) patients is known to be an important factor in the development of secondary hyperparathyroidism and renal osteodystrophy, phosphate binders have been needed for the control of serum phosphate levels (P). However, the calcium-containing phosphate binders that have been used widely can cause a rise in serum calcium levels and cause secondary hypoparathyroidism. We have recently experienced decreases in P after the administration of niceritrol (NT), a prodrug of nicotinic acid, for the treatment of low HDL-cholesteremia (HDL-C) in HD patients. The aim of the present study was to assess the mechanism of the P-lowering effect of NT in comparison with nicomol (NC), another prodrug of nicotinic acid. NT (750 mg/day) or NC (600 mg/day) was given orally to 10 or 14HD patients respectively. Blood samples were collected before the first dialysis of each week for the determination of serum urea nitrogen (UN), Cr, Ca, P, total cholesterol (TC), triglyceride (TG) and HDL-C. Serum nicotinic acid concentration (NAC) by gas chromatograph mass-spectrometry method was determined before, 4 weeks and 8 weeks after the administration of these drugs. After NT administration, P was decreased from 6.2 +/- 0.4 mg/dl to 5.1 +/- 0.4 mg/dl (1st week, p < 0.001, Mean +/- SE) and 4.5 +/- 0.3 mg/dl (2nd weeks, p < 0.001) with no change in UN, Cr or Ca levels; these significant decreases in P lasted for 8 weeks. NAC increased significantly after NT administration from 25.5 +/- 1.3 ng/ml to 549.8 +/- 102.2 ng/ml (4 weeks, p < 0.01) and 431.7 +/- 51.4 ng/ml (8 weeks, p < 0.01). HDL-C also increased (33.6 +/- 4.0 mg/dl vs 42.7 +/- 4.6 mg/dl, p < 0.05), but TC and TG did not change. In contrast, no significant changes were observed in P, NAC and HDL-C after NC administration. These discrepancies could be ascribed to the differences in serum NAC levels. These data suggest that NT could be useful for the control of P in HD patients. However further studies are needed to confirm the mechanism of the P-lowering effect of NT.

Abstract
Previous studies by the authors demonstrated that the response of urinary aquaporin-2 (AQP2) excretion to dDAVP (deamino-8-D-arginine vasopressin) infusion is an index of vasopressin action on the kidney (N Engl J Med 332: 1540-1545, 1995). In the study presented here, the characteristics of urinary excretion of AQP2 were examined further. An RIA suitable for AQP2 in the urine was established. Relatively high concentrations of detergent and bovine serum albumin in the RIA buffer allowed analysis of urine samples with a wide range of concentrations and increased the sensitivity of the assay. AQP2 in the urine existed as a high molecular weight form of approximately 190 kD by HPLC analysis. The mean urinary AQP2 concentration corrected for creatinine in spot urine samples of healthy subjects who voided in the morning was 1081 +/- 699 fmol/mg creatinine (mean +/- SD, n = 208). The amount of daily excretion of AQP2 in the urine was the same in men and women. Urinary AQP2 content was not affected by age of the subjects and showed a positive correlation with urine osmolality. Finally, the fraction of AQP2 excreted in the urine compared with whole kidney content was determined in the rat. Approximately 3% of AQP2 in the kidney was excreted daily, and this fraction did not change when rats were dehydrated for 3 d. These data demonstrate the necessity of establishing well-designed protocols to use urinary AQP2 as a marker of AVP action.

Abstract
The promoters of rat and mouse aquaporin-2 (AQP-2) genes were cloned and compared with that of human genes. Nucleotide identity up to -593 bp was 62%, and consensus sequences such as TATA box and adenosine 3',5'-cyclic monophosphate responsive element were conserved. Deoxyribonuclease I footprint assay revealed a footprinted region at -210 to -184 bp in rat AQP-2 gene promoter produced by nuclear extract from nonexpressing (liver) tissue. The sequence of this region included a GATA motif but otherwise showed no homology with any other previously known cis-elements. Electromobility shift assay and ultraviolet cross-linking analysis confirmed that specific binding proteins to this element were present in kidney, spleen, and liver and that these proteins were distinct from GATA factors. Both deletion and mutation of this cis-element abolished the protein DNA binding and increased promoter activity in in vitro reporter gene assay using rat cultured hepatocyte Ac2F cells, suggesting the negative regulatory role of this cis-element. These results indicate that tissue-specific expression of AQP-2 gene may in part be regulated by this novel negative acting cis-element.

Abstract
Aquaporin-2 (AQP-2) water channel is a key molecule for urinary concentration whose expression is augmented by dehydration in vivo. To elucidate the regulatory mechanism of this phenomenon in vitro, mouse collecting duct cell lines were established from a transgenic mouse harboring temperature-sensitive simian virus 40 large T antigen gene and then screened for the AQP-2 expression, using ribonuclease protection assay. In one cell line designated C4, the endogenous AQP-2 mRNA level measured by ribonuclease protection assay increased fourfold after treatment with chlorophenylthio-cAMP (cpt-cAMP) (400 microM). In contrast, phorbol 12-myristate 13-acetate did not affect the AQP-2 mRNA level. To identify the molecular mechanism(s) of cAMP-induced upregulation of AQP-2 mRNA in C4 cells, luciferase assay was performed using various 5'-flanking regions of the human AQP-2 gene. Luciferase activity in C4 cells transfected with constructs containing approximately 2.8-kbp or 224-bp 5'-flanking region showed a 3.5-fold increase by cpt-cAMP treatment, indicating that the 224-bp 5'-flanking region contains the elements necessary for cAMP-induced regulatory mechanisms. This region contains cAMP-responsive element (CRE), and the deletion of the core sequence of CRE (GACGTCA) or introduction of mutation into CRE (GTGGTCA) completely abolished the responsiveness to cpt-cAMP, confirming the key role of CRE in the cAMP-induced transcriptional activation of the AQP-2 gene. Electrophoretic mobility shift assay revealed the existence of proteins binding to CRE in C4 cells and in rat kidney. The binding of CRE proteins to CRE was increased in the nuclear extract from cpt-cAMP-treated C4 cells and dehydrated rat kidney compared with those from controls. These results demonstrated that the CRE in the AQP-2 gene promoter is a key cis-element for cAMP-mediated transcriptional regulation of this gene and may be important for in vivo regulation of AQP-2 expression in a dehydrated state.

Abstract
To evaluate the functional role of GATA motifs in the 5'-flanking region of a kidney-specific AQP-2 water channel gene, we sought to isolate a GATA factor(s) expressed in collecting ducts and determined the role on the AQP-2 promoter. Two cDNAs encoding GATA factors were isolated from rat kidney, whose sequences were highly homologous with human GATA-2 and -3. Reverse-transcription PCR using dissected nephron segments revealed that rat GATA-3 but not GATA-2 was expressed in collecting ducts, thus indicating that GATA-3 could interact with GATA motifs in the AQP-2 promoter. Transactivation experiments utilizing the rat GATA-3 expression vector indicated that rat GATA-3 increased the AQP-2 promoter activity about fourfold. These results indicated that GATA motifs in the 5'-flanking region of the hAQP-2 gene were functional cis-elements and that GATA-3 in collecting ducts may be one of the important regulators of AQP-2 expression in vivo.

Abstract
A total of 223 patients with 498 symptomatic osseous metastases treated by radiotherapy between July 1985 and June 1991 were retrospectively analyzed. Most sites, 409 (82%), were irradiated by conventional fractionation, while the remaining 89 sites were irradiated by dose-increment fractionation, low-dose short schedules or hyperfractionation. The total dose ranged from 5.4 to 74 Gy (mean, 41.4 Gy). Daily pain assessment was done by patients themselves on an 11-point scale, i.e., 10: pretreatment pain, 0: disappearance of pain following radiotherapy. In addition, improvement in performance status (PS) and the duration of complete pain relief were assessed. The following results were obtained. 1) Pain relief: Of 498 evaluated sites, complete pain relief and partial pain relief were achieved in 403 sites (81%) and 64 sites (13%), respectively. No significant difference was seen in the incidence of complete pain relief between weight-bearing bone and non-weight-bearing bone. Patients with PS 1, 2 or 3 were significantly superior to those with PS 4 in terms of complete pain relief (P < 0.05-0.001). The complete response rate increased in accordance with the dose delivered, i.e., 49% at 20 Gy, 70% at 30 Gy and 77% at 40 Gy, in all of the 498 sites irradiated; 60%, 86% and 95% of 403 sites, respectively, achieved complete pain relief. Regarding the fractionation regimens, dose-increment fractionation was superior to both conventional fractionation and low-dose short schedules in terms of complete pain relief rate. 2) Improvement of PS: Of 223 evaluated patients, PS was improved 1 to 3 steps in 162 (73%) at the completion of radiotherapy. The improvement rates of patients with PS 2 or 3 were significantly better than those with PS 4 (P < 0.025, 0.001). 3) Duration of complete pain relief: Of 288 appraisable sites, the recurrence of pain was recognized in 23 (9%) at intervals of 3 to 21 months (median, 5 months). On the other hand, the duration of pain relief was 16 to 79 months (median, 32 months) in 26 sites of survivors, and 1 to 28 months (median, 5 months) in 239 sites of decreased patients. The mean total dose was 48.5 Gy (TDF: 82) to 62 sites with a duration of pain relief of more than 13 months. 4) Re-irradiation to the same site: Of 14 sites retreated after initial complete response with a total dose of 30 to 50 Gy (mean, 48 Gy), 11 (79%) were in weight-bearing bone and 9 (64%) responded completely. 5) Patients with unsatisfactory pain relief (pain score > or = 6): Of 31 sites, 27 (94%) were in patients with PS 4, and 19 (61%) received a total dose below 30 Gy. 6) The 11-point scale for patient self-assessment of pain relief following radiotherapy was thought to be useful and easy to adopt in general clinics.

Abstract
The effects of antimetabolites on the growing dynamics of human bone marrow stromal cells and their support of hemopoietic cells were tested by using a modified version of Dexter's culture system. Cytosine arabinoside (ara-C) was found to suppress neither the growing dynamics nor the supportability. On the other hand, methotrexate (MTX) suppressed the supportiveness, even though it hardly suppressed the growing dynamics. The recognition of injury to marrow cells could be of potential importance in cancer chemotherapy. Our in vitro evidence may provide clinical insights for cancer chemotherapy including prolonged marrow suppression or pretreatment of bone marrow transplantation.

Abstract
Viral retinochoroiditis was induced experimentally by inoculation of herpes simplex virus into the vitreous body in rabbits. The animals were sensitized systemically using 2 pathogens as antigens (herpes simplex virus and toxoplasma gondii) 3 weeks prior to intraocular inoculation. Serum and intraocular fluid were collected 2 weeks after inoculation. The intraocular fluid antibody titers and quotients for these 2 pathogens were then measured to determine the effects of serum antibodies, which are thought to enter the eyes as a result of destruction of the blood-ocular barrier. Experimental criteria for antibody quotients were also determined. Antibody quotients for the etiological virus (herpes simplex virus) ranged from 2 to 20, with an average of 9.7. Those for toxoplasma gondii, the antibody of which is thought to enter the eye from the blood, were all less than 5 with average of 1.9. From these results, it would seem that when the antibody quotient of a pathogen in more than 6 in the intraocular fluid, it is likely to be an etiological organism, while the possibility of infection is very low when the quotient is under 2. More precise studies are required to identify an etiological pathogen when the quotient is 2-6.
