Abstract
INTRODUCTION/AIMS Duchenne muscular dystrophy (DMD) presents with skeletal muscle weakness, followed by cardiorespiratory involvement. The need for longitudinal data regarding DMD that could serve as a control for determining treatment efficacy in clinical trials has increased notably. The present study examined the longitudinal data of Japanese DMD patients collectively and assessed individual patients with pathogenic variants eligible for exon-skipping therapy. METHODS Patients with DMD who visited Kobe University Hospital between March 1991 and March 2019 were enrolled. Data between the patients' first visit until age 20 years were examined. RESULTS Three hundred thirty-seven patients were included. Serum creatine kinase levels showed extremely high values until the age of 6 years and a rapid decline from ages 7-12 years. Both the median 10-m run/walk velocity and rise-from-floor velocity peaked at the age of 4 years and declined with age. The values for respiratory function declined from the age of 11 years. The median left ventricular ejection fraction was >60% until the age of 12 years and rapidly declined from ages 13-15 years. Examination of the relationship between pathogenic variants eligible for exon-skipping therapy and longitudinal data revealed no characteristic findings. DISCUSSION We found that creatine kinase levels and motor, respiratory, and cardiac functions each exhibited various changes over time. These findings provide useful information about the longitudinal data of several outcome measures for patients with DMD not receiving corticosteroids. These data may serve as historical controls in comparing the natural history of DMD patients not on regular steroid use in appropriate clinical trials.

Abstract
Background Psychological readiness to return to sports (RTS) has been associated with second anterior cruciate ligament (ACL) injury. However, this relationship is controversial because covariates such as anatomic and knee function characteristics have not been adequately considered. Purpose/Hypothesis To investigate whether psychological readiness in the early postoperative period can predict the occurrence of a second ACL injury within 24 months after primary ACL reconstruction (ACLR) using propensity score analysis. It was hypothesized that patients with high ACL-RSI after injury (ACL-RSI) scores at 3 months postoperatively would have a second ACL injury within the projected postoperative period. Study Design Cohort study; Level of evidence, 3. Methods Included were 169 patients who underwent primary ACLR using hamstring tendon autografts between November 2017 and July 2021 and also underwent knee functional assessments at 3 months postoperatively. The ACL-RSI scale was used to assess psychological readiness for RTS. A second ACL injury was defined if ipsilateral or contralateral ACL injury was confirmed by examination within 24 months postoperatively. Based on a previous study showing that 65 was the highest cutoff value for the ACL-RSI score for RTS, we classified patients into 2 groups: those with high ACL-RSI scores (≥65; group H) and those with low ACL-RSI scores (<65; group L). We generated 1-to-1 matched pairs using propensity score analysis and used log-rank testing to compare the rate of second ACL injury between the 2 groups. Results More patients returned to any sports activities within 12 months in group H than in group L (90% vs 73%; P = .03). A second ACL injury within 24 months postoperatively was identified in 7% of patients (13/169). The rate of second ACL injury was significantly higher in group H than in group L (17.6% vs 3.4%; P = .001). In 43 matched pairs extracted using propensity scoring, the rate of second ACL injury was also higher in group H than in group L (18.6% vs 4.7%; P = .04). Conclusion Patients with a higher ACL-RSI score at 3 months exhibited a significantly higher incidence of second ACL injury within 24 months after primary ACLR.

Abstract
OBJECTIVES To describe the treatment of four dogs with splenophrenic shunts using percutaneous shunting vessel embolisation with Amplatzer vascular plugs II and IV and provide information on their clinical outcomes. MATERIALS AND METHODS Dogs with splenophrenic shunts treated at a veterinary hospital from January 2019 to December 2022 were identified through a medical record search. RESULTS Six dogs with splenophrenic shunts were identified. Two dogs were excluded because they were treated with laparoscopic surgery. Four underwent percutaneous shunting vessel embolization with Amplatzer vascular plugs and were included in the case series. A sheath was placed in the left external jugular vein and a balloon catheter was advanced to the shunting vessel under fluoroscopy. Portal vein pressure was confirmed to be within an acceptable range during temporary balloon occlusion. Based on preoperative CT angiography and intraoperative contrast examination, Amplatzer vascular plugs II were selected for two dogs and IV were selected for two dogs. Under fluoroscopy, the plug was deployed into the shunting vessel, and angiography confirmed occlusion. In all cases, the increase in portal pressure after temporary occlusion was within the acceptable range, and complete occlusion of blood flow was possible with a single plug. There were no major procedure-related complications. No dogs developed post-ligation seizures or signs of portal hypertension. In addition, improvements in ammonia values were observed in all cases. CLINICAL SIGNIFICANCE Percutaneous splenophrenic shunt embolisation using Amplatzer vascular plugs II and IV is technically feasible in dogs, and assessed by intra-procedure angiography, a single plug completely obstructed blood flow in all dogs. Based on the literature search, this is the first report describing Amplatzer vascular plugs for the treatment of splenophrenic shunts.

Abstract
PURPOSE This study compared the predictive ability of each independent predictor with that of a combination of predictors for quadriceps strength recovery one year after anterior cruciate ligament (ACL) reconstruction. METHODS Patients who underwent primary ACL reconstruction using hamstring autografts were enrolled. Quadriceps strength, hamstring strength, and anterior tibial translation were measured, and the limb symmetry index (LSI) of the quadriceps and the hamstrings was calculated preoperatively and one year after surgery. Patients were classified into two groups according to the LSI of the quadriceps strength at one year postoperatively (≥ 80% or < 80%). Multivariate logistic regression analysis identified the independent predictors of quadriceps strength recovery, and the cut-off value was calculated using the receiver operating characteristic curve. A model assessing predictive ability of the combination of independent predictors was created, and the area under the curve (AUC) for each independent predictor was calculated by using the receiver-operating characteristic curves and the DeLong method. RESULTS Of the 646 patients, 414 (64.1%) had an LSI of at least 80% for quadriceps strength one year after surgery, and 232 patients (35.9%) had an LSI of < 80%. Age, sex, body mass index (BMI), preinjury sport level, and LSI of preoperative quadriceps strength were independently associated with quadriceps strength recovery one year after ACL reconstruction. The cut-off values were age: 22.5 years; sex: female; BMI: 24.3 kg/m2; preinjury sport level: no sport; and LSI of preoperative quadriceps strength: 63.3%. The AUC of the model assessing the predictive ability of the combination of age, sex, BMI, preinjury sport level, and LSI of preoperative quadriceps strength was significantly higher (0.73) than that of similar factors of preoperative quadriceps strength (AUC: 0.63, 0.53, 0.56, 0.61, and 0.68, p < 0.01, respectively). CONCLUSION The combination of age, sex, BMI, preinjury sport level, and LSI of preoperative quadriceps strength had a superior predictive ability for quadriceps strength recovery at one year after ACL reconstruction than these predictors alone. Multiple factors, including patient characteristics and preoperative quadriceps strength, should be considered when planning rehabilitation programs to improve quadriceps strength recovery after ACL reconstruction.

Abstract
Background: The relationship between meeting return-to-sport criteria and psychological readiness after anterior cruciate ligament (ACL) reconstruction is unknown. Purposes: To examine (1) whether patients who met 1 of the criteria for return to sport had higher psychological readiness than those who did not meet any of the criteria and (2) if those who met more criteria had higher psychological readiness. Study Design: Cross-sectional study; Level of evidence, 3. Methods: This study included 144 patients who underwent unilateral ACL reconstruction. All patients had regularly participated in some sport activities before an ACL rupture. At 12 months postoperatively, each patient completed 3 knee function tests (isokinetic quadriceps strength, isokinetic hamstring strength, and single-leg hop distance) and 2 self-reported measures (International Knee Documentation Committee [IKDC] 2000 subjective form and ACL–Return to Sport after Injury [ACL-RSI] scale); the ACL-RSI scale was used to measure psychological readiness to return to sport. The 4 criteria for return to sport were a limb symmetry index (LSI) ≥90% for each of the 3 function tests in addition to an IKDC score ≥90. Multivariate regression analysis was used to determine the association between meeting the individual criteria and the ACL-RSI score. In addition, the patients were divided into 5 groups according to the number of criteria met, and the Kruskal-Wallis and Steel-Dwass tests were used to compare the ACL-RSI scores among the groups. Results: Overall, 23 patients (16.0%) met none of the criteria for return to sport, 27 (18.7%) met 1 of the criteria, 34 (23.6%) met 2 criteria, 35 (24.3%) met 3 criteria, and 25 (17.4%) met all 4 criteria. Meeting the criteria for the hamstring strength LSI (P = .002), single-leg hop distance LSI (P = .004), and IKDC subjective score (P < .001) was each associated with higher ACL-RSI scores. Significant differences in ACL-RSI scores were found between patients who met none versus 2, 3, and 4 of the return-to-sport criteria (P < .001 for all) and between patients who met 1 versus 4 criteria (P < .001). Conclusion: Meeting return-to-sport criteria was positively associated with psychological readiness, and the patients who met multiple criteria had higher psychological readiness.

Abstract
BACKGROUND Few studies have examined patient satisfaction with playing pre-injury sports after anterior cruciate ligament (ACL) reconstruction. The purpose of this study was to investigate patient satisfaction with playing pre-injury sport and identify factors associated with satisfaction. METHODS A total of 97 patients underwent unilateral ACL reconstruction using a hamstring autograft and returned to pre-injury sports 1 year after surgery. Patient satisfaction with playing pre-injury sport was assessed by a visual analog scale (VAS) and an ordinal four-grade scale. Problems related to the operated knee were also assessed. Knee muscle strength, single leg hop distance, knee laxity, subjective knee pain, and fear of movement/reinjury using Tampa Scale for Kinesiophobia-11 (TSK-11) were measured. Multivariate linear regression analysis was performed to determine the factors associated with patient satisfaction with playing pre-injury sport 1 year after surgery. RESULTS The average VAS score for patient satisfaction with playing pre-injury sports 1 year after surgery was 77.8 ± 20.2. Of the 97 patients, 87 patients (89.7%) answered "satisfied" or "mostly satisfied", whereas 51 patients (52.6%) had one or more problems. Multivariate linear regression analysis identified that the TSK-11 score was associated with patient satisfaction with playing a pre-injury sport 1 year after surgery. CONCLUSION Most of the patients who returned to pre-injury sports were satisfied with their outcomes. In contrast, approximately half of the patients had one or more problems after returning to play pre-injury sports. In particular, fear of movement/reinjury was significantly associated with patient satisfaction with playing pre-injury sport 1 year after surgery.

Abstract
BACKGROUND The wide variations in patient demographics and concomitant injuries make the prediction of which patients will regain strength quickly following anterior cruciate ligament (ACL) reconstruction challenging. This study aimed to identify the dominant factor affecting quadriceps strength recovery after ACL reconstruction with a hamstring tendon autograft and to construct a predictive model for quadriceps strength recovery using decision tree analysis. METHODS Three hundred and eighty-six patients who underwent ACL reconstruction with a hamstring tendon autograft were included in this study. The isokinetic quadriceps strength at 60°/s was measured preoperatively and at 6 months after surgery. The quadriceps strength index (QSI) was calculated by normalising the peak torque of the involved leg with the uninvolved leg and multiplying it by 100. A stepwise multiple linear regression and a decision tree analysis were performed to assess whether or not the following parameters affect quadriceps strength recovery at 6 months: socio-demographic data and maximum isokinetic quadriceps strength. RESULTS The preoperative QSI, age, and pre-injury Tegner activity scale were independently correlated with quadriceps strength recovery at 6 month after surgery. The decision tree analysis demonstrated that patients were expected to have a QSI ≥85% at 6 months after surgery if they met one of the following conditions: (1) age <23 years with a preoperative QSI ≥78.8%, (2) age ≥29 years with a preoperative QSI ≥98.0%, or (3) age <16 years with a preoperative QSI <58.5% and pre-injury Tegner activity scale ≥9. By contrast, patients ≥29 years with a preoperative QSI <98.0% were likely to achieve a quadriceps strength index <70% at 6 months after surgery. CONCLUSIONS Based on the results of the decision tree analysis, younger patients could achieve good quadriceps recovery even if they have a lower preoperative QSI, whereas patients ≥29 years need a higher preoperative QSI to obtain good muscle recovery.

Abstract
PURPOSE Patients typically return to sports activities 6-12 months after anterior cruciate ligament (ACL) reconstruction, and quadriceps strength has been used as one of the criteria to return to sports activities. The purpose of this study is to identify the factors that affect quadriceps strength recovery after ACL reconstruction with a hamstring tendon autograft 6 months after surgery. METHODS Isokinetic quadriceps strength at 60°/s was measured preoperatively and 6 months after surgery in 193 athletes who underwent ACL reconstruction with a hamstring tendon autograft. The quadriceps strength index was calculated by normalizing the peak torque of the involved leg with the uninvolved leg. The subjects were divided into two groups according to the quadriceps strength index 6 months after surgery: at least 85 % (n = 84) or less than 85 % (n = 109). Multivariate logistic regression analysis and a receiver operating curve analysis were performed. RESULTS The preoperative quadriceps strength index [odds ratio (OR) 1.02; 95 % confidence interval (CI) 1.01-1.03], age (OR 0.92; 95 % CI 0.86-0.98), sex (OR 2.45; 95 % CI 1.19-5.18), and knee pain (OR 0.17; 95 % CI 0.04-0.52) were independently associated with quadriceps strength recovery. The cut-off value of the preoperative quadriceps strength index was 70.2 % to obtain at least 85 % quadriceps strength index 6 months after surgery. CONCLUSION To achieve sufficient quadriceps strength recovery at the timing of return to sports activities following ACL reconstruction using a hamstring tendon autograft, preoperative quadriceps strength, age, sex, and knee pain should be considered.

Abstract
The purpose of this study was to investigate whether long-term wheel running would attenuate age-related loss of muscle fiber. Male ICR mice were divided into young (Y, n=12, aged 3 months), old-sedentary (OS, n=5, aged 24 months), and old-exercise (OE, n=6, aged 24 months) groups. The OE group started spontaneous wheel running at 3 months and continued until 24 months of age. Soleus and plantaris muscles were fixed in 4% paraformaldehyde buffer. The fixed muscle was digested in a 50% NaOH solution to isolate single fiber and then fiber number was quantified. The masses of the soleus and plantaris muscles were significantly lower at 24 months than at 3 months of age, and this age-related difference was attenuated by wheel running (P<0.05). Soleus muscle fiber number did not differ among the groups. In the plantaris muscle, the fiber number in the OS group (1 288±92 fibers) was significantly lower than in the Y group (1 874±93 fibers), and this decrease was attenuated in the OE group (1 591±80 fibers) (P<0.05). These results suggest that age-related fiber loss occurs only in the fast-twitch fiber-rich muscle of mice, and that life-long wheel running exercise can prevent this fiber loss.

Abstract
BACKGROUND Idiopathic mesenteric phlebosclerosis (IMP) is a rare disease, characterised by thickening of the wall of the right hemicolon with calcification of mesenteric veins. However, the aetiology remains unknown. AIM To investigate the possible association of herbal medicines with IMP. METHOD The clinical data of four of our own patients were collected. Furthermore, we searched for previous reports about similar patients with detailed descriptions of herbal prescriptions that they had taken. We compared herbal ingredients to identify the toxic agent as a possible aetiological factor. RESULTS Clinical data on a total of 25 patients were summarised. Mean age was 61.8 years and there was female predominance (6 men and 19 women). The used Kampo prescription, the number of cases, and the mean duration of use were as follows: kamisyoyosan in 12 cases for 12.8 years, inshin-iseihaito in 5 cases for 13.4 years, orengedokuto in 4 cases for 14.3 years, inchinkoto in 1 case for 20 years, kamikihitou in 1 case for 19 years, seijobofuto in 1 case for 10 years and gorinsan in 1 case for an unknown duration. Only one ingredient, sansisi, was common to the herbal medicines of all 25 patients. This crude drug called geniposide in English is a major constituent of the Gardenia fruits. CONCLUSION The long-term use of geniposide in herbal medicines appears to be associated with mesenteric phlebosclerosis.

Abstract
INTRODUCTION Adeno-carcinomas of pancreatic body are usually asymptomatic and progress to advanced stage with involvement of major arteries. Resection of advanced cancer along with en bloc resection of a common hepatic artery and celiac trunk enables a "curative" resections and only possible treatment. However, the celiac axis resection always has a risk of compromising blood supply to liver, resulting in the hepatic insufficiency. We evaluated practicability of a two-stage procedure for the advanced pancreases body cancer, laparoscopic clamping of a common hepatic artery followed by open distal pancreatectomy with en bloc celiac arterial resection to prevent the hepatic insufficiency. MATERIALS AND SURGICAL TECHNIQUE Seventy-five-year-old woman diagnosed with a 50-mm pancreatic body mass, invading splenic artery, common hepatic artery, splenic vein, and portal vein at the confluence. STAGE-1: At laparoscopy, after confirming absence of the peritoneal, superficial liver metastases and negative peritoneal cytology; we approached the common hepatic artery through the lesser sac and ligated. STAGE-2: Her liver function tests were normal after 2 weeks, and CT angiography showed complete blockage of the common hepatic artery with sufficient collateral circulation to the liver through inferior pancreatico-duodenal artery and gastro-duodenal artery. We performed an open distal pancreatectomy with en bloc resection of celiac artery. Histopathology examination confirmed R0 resection. DISCUSSION The celiac axis resection with distal pancreatectomy improves the chance of R0 resection and potentially, survival of the patient. Preoperative laparoscopic ligation of the common hepatic artery is a safe, effective, and in-expensive technique to prevent postoperative hepatic insufficiency and improves the safety of en bloc celiac artery resection with a distal pancreatectomy. Also these patients have high risk of peritoneal dissemination. Diagnostic laparoscopy is useful to detect occult metastasis, which are missed by per-operative CT scan.

Abstract
To predict the efficacy of cisplatin and radiation therapy for maxillary squamous cell carcinoma, we examined the mRNA expression of 14 cisplatin-resistant genes and p53 mutation in specimens biopsied from patients prior to initiation of therapy. Five of 10 patients had mutations in the p53 gene, of whom four had residual tumors pathologically following chemoradiotherapy (p=0.0476). Of 14 genes examined, the mRNA expression of ATP7B was significantly lower in cases that were resistant to chemoradiotherapy. Six genes including multidrug resistance protein 1 (MDR-1), multidrug resistance associated protein 1 (MRP-1), Cu++ transporting, beta polypeptide (ATP7B), xeroderma pigmentosum, complementation group A (XPA), excision repair cross-complementing rodent repair deficiency, complementation group 1 (ERCC-1) and B-cell CLL/lymphoma 2 (BCL2) were down-regulated in cases of recurrent cancers. These results show that the evaluation of p53 mutation provides the most useful predictor of therapeutic effects. In responder cases, the drug-resistant genes that were determined in cell lines by culture do not necessarily translate into clinical relevance.

Abstract
Cyclin D2 plays an important role in regulation of hematopoietic cell proliferation by cytokines and is implicated in oncogenesis of various hematopoietic malignancies. However, mechanisms regulating cyclin D2 stability and its expression level have remained to be known. Here, we demonstrate that interleukin-3 signaling stabilizes cyclin D2 by inhibition of glycogen synthase kinase-3beta (GSK3beta) through Janus kinase2-dependent activation of phosphatidylinositol 3'-kinase (PI3K)/Akt signaling pathway in hematopoietic 32Dcl3 cells. On the other hand, osmotic stress was shown to induce a rapid proteasomal degradation of cyclin D2, which was mediated by activation of p38. GSK3beta and p38 was demonstrated to phosphorylate cyclin D2 on Thr280 in vitro, while a cyclin D2 mutant with this residue substituted with Ala was found to be resistant to ubiquitination and proteasome-dependent degradation in 32Dcl3 cells. Inhibition of the PI3K pathway or induction of osmotic stress also caused a rapid proteasomal degradation of cyclin D2 in primary leukemic or myeloma cells. These results indicate that cyclin D2 expression in normal and malignant hematopoietic cells is regulated by ubiquitin/proteasome-dependent degradation that is triggered by Thr280 phosphorylation by GSK3beta or p38, which is induced by inhibition of the PI3K pathway or by osmotic stress, respectively.

Abstract
Although the BCR/ABL tyrosine kinase inhibitor imatinib is highly effective for treatment of chronic myeloid leukemia (CML) and Philadelphia-chromosome positive acute lymphoblastic leukemia (ALL), relapse with emerging imatinib-resistance mutations in the BCR/ABL kinase domain poses a significant problem. Here, we demonstrate that rottlerin, a putative protein kinase C-delta (PKCdelta)-specific inhibitor, acts synergistically with imatinib to induce apoptosis of BCR/ABL-expressing K562 and Ton.B210 cells. However, rottlerin inhibited neither PKCdelta nor BCR/ABL in these cells. On the other hand, rottlerin, previously characterized also as a mitochondrial uncoupler, transiently but significantly reduced mitochondrial membrane potential and gradually induced mitochondrial membrane permeabilization. Moreover, two other mitochondrial uncouplers, FCCP and DNP, very similarly induced apoptosis of BCR/ABL-expressing cells in a synergistic manner with imatinib. Imatinib synergistically enhanced mitochondrial membrane permeabilization induced by mitochondrial uncouplers, which led to release of cytochrome c into the cytoplasm and activation of caspases-3 and -9. Rottlerin also enhanced the cytotoxic effect of imatinib in leukemic cells from patients with CML blast crisis and Ph-positive ALL or a cell line expressing the imatinib-resistant E255K BCR/ABL mutant. The present study indicates that rottlerin synergistically enhances imatinib-induced apoptosis through its mitochondrial uncoupling effect independent of PKCdelta and may contribute to the development of new treatment strategy to overcome the imatinib resistance and to cure the BCR/ABL expressing leukemias.

Abstract
Although calcium carbonate is known to be a common biomineral in plants, very little attention has been given to the biological control of calcium carbonate deposition. In mulberry leaves, a subcellular structure is involved in mineral deposition and is described here by a variety of cytological techniques. Calcium carbonate was deposited in large, rounded idioblast cells located in the upper epidermal layer of mulberry leaves. Next to the outmost region ("cap") of young idioblasts, we found that the inner cell wall layer expanded to form a peculiar outgrowth, named cell wall sac in this report. This sac grew and eventually occupied the entire apoplastic space of the idioblast. Inside the mature cell wall sac, various cellulosic membranes developed and became the major site of Ca carbonate deposition. Concentrated Ca2+ was pooled in the peripheral zone, where small Ca carbonate globules were present in large numbers. Large globules were tightly packed among multiple membranes in the central zone, especially in compartments formed by cellulosic membranes and in their neighboring membranes. The maximum Ca sink capacity of a single cell wall sac was quantified using enzymatically isolated idioblasts as approximately 48 ng. The newly formed outgrowth in idioblasts is not a pure calcareous body but a complex cell wall structure filled with substantial amounts of Ca carbonate crystals.

Abstract
The purpose of this study was to determine the feasible adjuvant therapy administration schedule of S-1 for locoregionally advanced squamous cell carcinoma of the head and neck (SCCHN). Patients receiving definitive treatments were randomly assigned to either arm A (51 cases) receiving oral S-1 of 2-week administration followed by 1-week rest for 6 months, or arm B receiving S-1 of 4-week administration followed by 2-week rest for 6 months. Planned treatment was given in 40% of patients in arm A and 29% in arm B. The cumulative rates of the relative total administration dose of S-1 at 100% were 54.9% (95% CI: 40.1–69.7%) in arm A and 34.3% (95% CI: 21.1–47.4%) in arm B, respectively (P=0.054). Adverse events were recorded in 41 patients (82.0%) in arm A and 48 patients (94.1%) in arm B (P=0.060). The incidences of diarrhoea (10 vs 28%; P<0.05) and skin toxicities (18 vs 37%; P<0.05) were significantly higher in arm B. One-year disease-free survival was similar in both arms: arm A 81.2% (95% CI: 70.0–92.4%); arm B 77.0% (95% CI: 65.0–89.0%). The schedule of 2-week administration followed by 1-week rest seems to be more feasible for oral 6-month administration of S-1 in adjuvant chemotherapy of locoregionally advanced SCCHN.

Abstract
The pathogenesis of Sjögren's syndrome (SS) is poorly understood. In this study we used an in-house mouse spleen cDNA microarray to analyse genes in spleens from MRL/lpr (an SS mouse model) mice. We have previously demonstrated that GRAP genes were up-regulated in salivary glands of the same mice. The microarray analysis showed that seven out of 2304 genes were highly expressed in spleens from the MRL/ lpr mice, one of which was the GRAP gene. In other words, the GRAP gene is highly expressed in the salivary glands and spleen of MRL/lpr mice. We also carried out immunohistochemical studies. Mouse and human Grb-2-related adaptor protein ( GRAP) antigens were expressed on ductal cells and infiltrating lymphocytes in salivary glands of MRL /lpr mice and SS patients, but only weakly in controls (MRL/+ mice and individuals with salivary cysts). These results suggest that the GRAP gene might have a role in the pathogenesis of SS.

Abstract
In order to elucidate the primary stage in the blepharismin phototransduction pathway, changes in the molecular structure of light-exposed blepharismins and oxyblepharismins, were examined. When exposed to light, blepharismins (pink form) were converted into oxyblepharismins (blue form) or dissociated into stentorins/p-hydroxybenzaldehyde with an O2-requiring process, whereas light-exposed oxyblepharismins were not dissociated into stentorins/p-hydroxybenzaldehyde. Since both blepharismins and oxyblepharismins can activate the phototransduction chain leading to the step-up photophobic response presumably through the same pathway, dissociation of p-hydroxybenzaldehyde may not be involved in signal transduction. The fact that the step-up photophobic response requires O2, and both blepharismins and oxyblepharismins produce hydroxyl (OH) radicals probably derived from O2 implies that OH radicals may activate the photosignalling pathway. The step-up photophobic response was not suppressed by a spin trapping reagent for hydroxyl radicals. Other possible primary responses leading to the step-up photophobic response are discussed.

Abstract
OBJECTIVES Most tracheobronchial foreign bodies in children are radiolucent, and accurate diagnosis of such foreign bodies is not always easy. This can result in delay of diagnosis or misdiagnosis of foreign body aspiration. We report the usefulness and pitfalls of use of digital subtraction fluoroscopy (DSF) to diagnose radiolucent aspirated foreign bodies in infants. METHODS From 1991 through 1999, DSF was conducted for a total of 19 patients (ranged from 11 months to 4 years and 7 months in age (mean 1.8+/-0.9 years)) who were suspected to have radiolucent aspirated foreign bodies. Since DSF revealed abnormal findings in a trachea or main bronchus in 18 cases, inspection was performed for foreign body bronchofiberscopically. In the one remaining case, no abnormality was recognized on DSF, but since the symptoms at the time of onset strongly suggested aspirated foreign body, bronchofiberscopy was also performed. RESULTS Foreign body was verified bronchoscopically in 13 of 19 cases, and all 13 (100%) had abnormal findings on DSF, including obstruction of the trachea in two, obstruction of the bronchial lumen in nine, and indistinct visualization of the bronchial lumen in two. Bronchial stenosis was verified bronchoscopically in five of the remaining six cases, including mucus plug in three, granuloma in one and mucosal edema in one case. All five patients (100%) had abnormal findings on DSF, including obstruction of the bronchial lumen in four and indistinct visualization of the bronchial lumen in one. In the one remaining patient with normal findings of DSF, no foreign body or pathological bronchial changes were noted. CONCLUSIONS DSF was very sensitive in the diagnosis of foreign body aspiration and stenotic changes in the bronchial lumen. However, its diagnostic specificity for aspirated foreign body itself was not high (17%). Therefore, when abnormalities are found on DSF, we recommend to perform flexible bronchofiberscopy initially under general anesthesia via a tracheal tube. When a foreign body is verified, rigid ventilation bronchoscopy is successively performed to retrieve the foreign body.

Abstract
Blepharismins are polycyclic quinones found in the pigment granules of the ciliated protozoan, Blepharisma. Exposure to purified blepharismins results in lethal damage to several other ciliates. We here report that, at cytotoxic concentrations, blepharismins formed cation-selective channels in planar phospholipid bilayer membranes. The channels formed in a diphytanoylphosphatidylcholine bilayer had a K(+)/Cl(-) permeability ratio of 6.6:1. Single channel recordings revealed the conductance to be quite heterogeneous, ranging from 0.2 to 2.8 nS in solutions containing 0.1 M KCl, possibly reflecting different states of aggregation of blepharismin. Our observations suggest that channel formation is a cytotoxic mechanism of blepharismin's action against predatory protozoa.

Abstract
Abnormalities of chromosome 16 other than inv(16)(p13q22), t(16;16)(p13;q22), and del(16)(q22) have not been fully characterized in acute myeloblastic leukemia (AML) and myelodysplastic syndrome (MDS). We report here the first case of AML with del(16)(q11) as a sole abnormality. A 53-year-old woman was initially diagnosed as MDS, refractory anemia with excess of blasts in transformation with normal karyotype. After sixteen months, the disease progressed to overt AML-M1. Myeloblasts were positive for CD13, CD33, and CD34, but negative for HLA-DR. Chromosome analyses of the bone marrow cells showed 46,XX,del(16)(q11) in all metaphase spreads. Multicolor spectral karyotyping also confirmed that del(16)(q11) was not derived from a cryptic translocation, but a simple deletion. Our results, together with three previously reported cases, suggest that del(16)(q11) may be one of the recurrent aberrations in AML and that it could be associated with clonal evolution or disease progression.

Abstract
Near-tetraploidy is a rare cytogenetic abnormality observed in acute myeloblastic leukemia (AML). It was recently suggested that near-tetraploid AML may be associated specifically with t(8;21)(q22;q22). We report here a new case of near-tetraploid AML with double t(8;21)(q22;q22) translocations. A 61-year-old woman was admitted to our hospital because of high fever and pancytopenia. Her bone marrow was markedly hypercellular, with 72% giant and bizarre myeloblasts. These myeloblasts were positive for CD7, CD13, CD19, CD33, CD34, and HLA-DR but negative for CD2 and CD56. The patient's disease was diagnosed as the M2 subtype of AML (by French-American-British classification). Chromosome analysis revealed a karyotype of 45,X,-X, t(8;21) (q22;q22)[1]/90,XXX,-X,t(8;21)(q22;q22)x2,-9[7]/46,XX[12]. Fluorescence in situ hybridization (FISH) analysis with an AML1/ ETO probe detected 4 fusion signals on 2 der(8)t(8;21) and 2 der(21)t(8;21) in near-tetraploid cells. Reverse transcription-polymerase chain reaction analysis revealed the presence of the AML1/ETO fusion transcript. These findings suggested that near-tetraploidy may be a secondary genetic change originating from a diploid clone with t(8;21) and that 2 AML1/ETO fusion genes are generated on the der(8)t(8;21) in near-tetraploid clones. Consideration of the other reported cases suggests that the immunophenotypes of near-tetraploid AML with double t(8;21) are heterogenous, but it is possible that t(8;21)-AML with expression of CD2 or CD7 may be associated with a secondary clonal evolution to near-tetraploidy.

Abstract
A late phase II clinical study of S-1, a novel oral antitumor agent of fluorinated pyrimidines, in patients with advanced/recurrent head and neck cancer was conducted in 25 institutions across Japan as a multi-institutional cooperative study from August 1995 to March 1998. Out of 59 eligible patients, the objective responses were 4 complete responses (CR) and 13 partial responses (PR). The response rate was 28.8% (17/59, 95% CI: 17.8-42.1%). The response rate in previously treated patients was 28.3% (15/53), whereas that in treatment naive patients was 33.3% (2/6). The response rate in patients with prior chemotherapy was 26.7% (12/45). Major adverse reactions of grade 2 or more were anemia (25.4%, 15/59), leucopenia (22.0%, 13/59), neutropenia (25.4%, 15/59), thrombocytopenia (3.4%, 2/59), anorexia (6.8%, 4/59), nausea/vomiting (1.7%, 1/59), stomatitis (1.7%, 1/59), skin symptoms including eruptions or desquamation (5.1%, 3/59), and malaise (1.7%, 1/59). Grade 4 anemia was observed in one case; however, this returned to the normal level after the termination of drug administration and the blood transfusion. Therefore, this event was confirmed to be reversible. Based on these results, we conclude that S-1 is an active agent for the treatment of advanced/recurrent head and neck cancer.

Abstract
OBJECTIVE It is well known that the size of the human auricle increases after it has finished development. The reason why the size of the human auricle continues to enlarge until advanced age after reaching adulthood was investigated by observation of the ultrastructure of elastic fibers in human auricular cartilage. METHODS A total of 1958 subjects (966 males and 992 females) were classified into 18 age groups from 0 to 5 years up to 85 years and above by 5-year intervals. Ear length, ear width, and length of ear attachment were measured with calipers. Human auricular cartilage was obtained from 26 subjects (16 males and 10 females) aged 14 to 79 years, stained by orcein, and examined by light and electron microscopy. RESULTS Each item of measurement of human auricular size increased significantly with age in both males and females. On morphological examination by light and electron microscopy after orcein staining, elastic fibers in the cartilage were almost homogeneous in diameter and surrounded the cartilage lacuna in bundle-like fashion in young persons, whereas those in elderly persons were heterogeneous in thickness and had many fragments surrounding the territorial matrix. In elderly persons, collagen-like fibers and small vesicles with heterogeneous electron density were frequently observed near elastic bundles around the territorial matrix. CONCLUSION Structural changes of auricular cartilage associated with morphological age changes of elastic fibers may be one of the causes of expansion of the auricle after reaching adulthood.

Abstract
OBJECTIVE Japanese people are physically larger and live longer than in the past. In light of these changes, we studied anthropometric auricular morphology in Japanese people in all age groups. METHODS Subjects were 1,958 healthy Japanese people with no ear disease, 966 males aged 0-94 years and 992 females aged 0-99 years. They were classified at 5-year intervals into 18 age groups, and each group consisted of 50-72 persons. Bilateral size of auricles (ear length, ear width, length of ear attachment, auricular cartilage length, and auricular lobe length) were measured in the usual manner. All measurements were made with calipers by a single observer. RESULTS Larger values were obtained in males than in females in almost all age groups. Rapid growth was observed until late teenage, and significant growth continued thereafter until advanced age. Auricular size was found to be greater than that in Japanese people in the past. CONCLUSIONS In addition to changes in auricular size believed attributable to growth until late teenage, age-associated changes appear to continue during adulthood.

Abstract
The blepharismin-200 kD protein complex of the ciliated protozoan Blepharisma is a novel type of photosensor responsible for the step-up photophobic response of the cell. In immunoblotting assays, the 200 kD protein is weakly cross-reacted with anti-inositol triphosphate receptor antibody (anti-IP3 R antibody). Indirect immunofluorescence assays show that the pigment granules in which the blepharismin-200 kD protein complex is localized are labelled by anti-IP3 R antibody. When the anti-IP3 R antibody or antisense oligonucleotide for IP3 receptor is introduced into the living cells of Blepharisma, both the photosensitivity of the cells and content of blepharismin-200 kD protein are reduced. The results suggest that the photoreceptor 200 kD protein is possibly an IP3 receptor-like protein.

Abstract
PURPOSE The results of radiation therapy for metastatic spinal tumors were evaluated in terms of pain relief, improvement of neurological impairment, and survival. MATERIALS AND METHODS Between 1986 and 1995, 52 symptomatic patients with metastatic spinal tumors treated with radiation therapy were evaluated. The patients all received irradiation of megavoltage energy. Therapeutic efficacy was evaluated in terms of pain relief and improvement of neurological impairment. RESULTS Pain relief was observed in 29 (61.7%) of 47 patients with pain. Therapy was effective for 17 (70.8%) of 24 patients without neurological impairment, and efficacy was detected in 12 (52.2%) of 23 patients with neurological impairment. Improvement of neurological symptoms was obtained in seven (25.0%) of 28 patients with neurological impairment. CONCLUSION Radiation therapy was effective for pain relief in patients with metastatic spinal tumors. In patients with neurological impairment, less pain relief was observed than in those without impairment. Improvement of neurological impairment was restricted, but radiation therapy was thought to be effective in some cases in the early stage of neurological deterioration. Radiation therapy for metastatic spinal tumors contraindicated for surgery was considered effective for improvement of patients' activities of daily living.

Abstract
Eleven patients (12 ears) with acute otitis media associated with raised bone conduction were studied. The patients were from 19 to 70 years old and came to our hospital between November 1996 through May 1997. Pure tone audiometry revealed mixed hearing loss, but there was no bullous myringitis in all cases. They were treated by oral or intravenous antibiotics, steroids, and myringotomy. Bacteriological examination was done in seven cases, and revealed penicillin resistant Streptococcus pnumoniae in three cases. Complete recovery of hearing loss was obtained in 10 of 12 ears, but sensorineural hearing loss remained in 2 patients. Bacteriological examination and pure tone audiometry in acute otitis media are important for detecting the severity of the disease, determining the administration of steroids, and for the selection of antibiotics.

Abstract
UNLABELLED The nucleus raphe magnus (NRM) is an important descending inhibitory system for pain transmission. We tested whether clonidine, an alpha2-adrenergic agonist, and yohimbine, an alpha2-adrenergic antagonist, modulate the activity of NRM neurons using extracellular recording in a rat brainstem slice preparation. Clonidine 1-20 microM increased firing frequencies (FF) in 22 (37%) and decreased FF in 6 (10%) spontaneously active neurons. Correlation between the concentrations of clonidine and FF changes was unremarkable. Eight spontaneously active neurons (13%) showed increases followed by decreases in FF with increasing doses of clonidine. The remaining 24 neurons (40%) showed no change in FF. Yohimbine 1 microM decreased FF in 38 spontaneously active neurons (58%), whereas the remaining 27 neurons (42%) showed no change in FF. In some neurons, yohimbine antagonized the increase or decrease in FF by application of clonidine. In three silent neurons (25%), clonidine (5 or 10 microM) induced firing activity, which stopped or decreased with the increasing doses of clonidine. In the remaining nine neurons (75%), clonidine did not induce firing activity. We conclude that activation and inhibition of alpha2-adrenergic receptors of NRM neurons augments and suppresses output of the descending inhibitory pain pathway. IMPLICATIONS The nucleus raphe magnus is implicated in descending control of the nociceptive processes. We found that clonidine and yohimbine increased and decreased, respectively, the firing activity of a substantial number of nucleus raphe magnus neurons. Clonidine and may facilitate and yohimbine may reduce the outflow of the descending inhibitory pathway.
