Abstract
OBJECTIVES We simultaneously assessed ultrasonography (US) and magnetic resonance imaging (MRI) in comparison with histopathological changes in the knee joints of long-lasting arthritis patients. METHODS We studied 15 patients with rheumatoid arthritis and 5 patients with osteoarthritis, who underwent total knee arthroplasty. On the day before surgery, the joints were examined by US and contrast-enhanced MRI. In US, synovitis was graded with 0-3 grey scale (GSUS) and power Doppler (PDUS). In MRI, synovitis was graded according to OMERACT-RAMRIS (grade 0-3). Synovial tissue samples were obtained during arthroplasty and evaluated on the basis of inflammatory cell infiltrates (grade 0-3), synovial lining layer thickness (grade 0-3) and vascularity (grade 0-3). RESULTS Positive findings of PDUS and contrast-enhanced MRI were 45% and 85% of 20 operated joints, respectively. GSUS, PDUS and MRI synovitis were well correlated with overall histopathological grades of synovitis (Spearman correlation coefficients 0.48, 0.84 and 0.48, p<0.05, p<0.01 and p<0.05, respectively). Moreover, positive PDUS findings were closely associated with all pathological comportments of synovitis including inflammatory cell infiltrates, synovial lining layer thickness and vascularity. CONCLUSIONS The present study revealed that positive PDUS findings more faithfully illustrated active synovitis than MRI, whereas contrast-enhanced MRI was more sensitive in detecting synovitis in patients with long-lasting arthritis. It is important to understand distinct features of the both modalities for clinical assessment of chronic joint diseases.

Abstract
The present study was conducted to determine the morphological and functional interaction between kisspeptin and gonadotrophin-releasing hormone (GnRH) neuronal elements at the median eminence in female rats to clarify a possibility that kisspeptin directly stimulates GnRH release at the nerve end. A dual immunoelectron microscopic study of kisspeptin and GnRH showed that the kisspeptin-immunoreactive nerve element directly abutted the GnRH-immunoreactive nerve element, although no obvious synaptic structure was found between kisspeptin and GnRH neurones in the median eminence. The current retrograde tracing study with FluoroGold (FG) indicates that kisspeptin neurones are not in contact with fenestrated capillaries because no FG signal was found in kisspeptin neurones when the FG was injected peripherally. This peripheral FG injection revealed the neuroendocrine neurones projecting to the median eminence because FG-positive GnRH neuronal cell bodies were found in the preoptic area. Synthetic rat kisspeptin (1-52)-amide stimulated GnRH release from the median eminence tissues in a dose-dependent manner. Thus, the present results suggest that kisspeptin at least partly exerts stimulatory effects on GnRH release from the neuronal terminals of GnRH neurones by axo-axonal nonsynaptic interaction in the median eminence.

Abstract
We demonstrate a cold-atom interferometer gyroscope which overcomes accuracy and dynamic range limitations of previous atom interferometer gyroscopes. We show how the instrument can be used for precise determination of latitude, azimuth (true north), and Earth's rotation rate. Spurious noise terms related to multiple-path interferences are suppressed by employing a novel time-skewed pulse sequence. Extended versions of this instrument appear capable of meeting the stringent requirements for inertial navigation, geodetic applications of Earth's rotation rate determination, and tests of general relativity.

Abstract
AIM AND BACKGROUND The surgical treatment for acromioclavicular joint dislocations is recommended for Rockwood's classification types 4, 5 and 6. In this study we evaluate the therapeutic results of the modified Cadenat procedure on type 5 acromioclavicular joint dislocation, and report on a comparative study of the modified Dewar procedure also on type 5 acromioclavicular joint dislocation. SUBJECTS AND METHODS The modified Cadenat procedure was performed on 73 patients (66 males and 7 females, group C). The mean age at the time of the surgery was 35.4 years. On the other hand, the modified Dewar procedure was performed on 55 patients (51 males and 4 females, group D). The mean age at the time of the surgery was 34.5 years. RESULTS The mean therapeutic results were 28.2 points in group C and 27.3 in group D according to the UCLA scoring system. In group C, the subluxation that represented less than 5 mm superior translation of the clavicle, occurred only in 18 of 73 patients. Meanwhile, in group D, the subluxation that represented less than 5 mm, occurred only in 14; that which represented 5 to 10 mm was in seven patients, and the complete dislocation occurred in three patients. Also, the occurrence of osteoarthritic changes in the acromioclavicular joint was nine patients in group C and 20 in group D, respectively. CONCLUSION The modified Cadenat procedure could provide satisfactory therapeutic results and avoid postoperative failure of reduction compared to the modified Dewar procedure. However the modified Cadenat procedure does not aim to restore the anatomical coracoclavicular ligaments. It is believed that anatomic restoration of both coracoclavicular ligaments could best restore the function of the acromioclavicular joint.

Abstract
OBJECTIVE In this study, eighteen patients who have had perilunate injury with dislocation or fracture, were evaluated and the patho-mechanics and surgical treatment were studied. SUBJECTS AND METHODS According to the Green and O'Brien's classification, type 1 injury occurred in one patient, type 2 in nine, type 4A in five, type 4C in one and type 4D in one. The other one case could not be classified using the Green and O'Brien's criteria. RESULTS According to the Evans scoring system, good results were achieved in thirteen patients, fair results, in four, poor results in one and very poor results in none. When the patho-mechanics was estimated based on the Mayfield's criteria, seventeen patients were classified as stage 3. However only one case was extremely unusual and should be classified as a subtype of stage 2. CONCLUSION The results were good in the majority of patients who had repair of perilunate injury.

Abstract
BACKGROUND Since frozen shoulder is characterized by spontaneous recovery, no precise treatment strategy exists. Both conservative therapy and arthroscopic surgery is available, but the time required for recovery varies considerably. This study looks at the possible early symptom relief with oral steroid therapy. SUBJECTS AND METHODS The subjects were 76 patients aged 33 to 73 years at the beginning of the study. The duration of the frozen shoulder was one to 15 months (mean 5.7 months) and hypertension was noted in 13 patients as a complicated disorder. A single course of steroid therapy consisted of a total dose of 105 mg of prednisolone over approximately a three-week period by the dose-tapering method. The number of courses varied with the degree of symptom relief but the rest period between courses was always approximately four weeks. The results were assessed on the basis of the Japanese Orthopaedic Association (JOA) score, but the principal evaluations were pain and range of motion. RESULTS The average ranges of motion before treatment were 102.8 degrees of forward flexion 11.3 degrees of external rotation and internal, rotation was at the buttocks. However, after one course of treatment, forward flexion was 136 degrees, external rotation was 33.7 degrees, and internal rotation was limited to the buttocks in only six cases. CONCLUSION The results of oral steroid therapy for frozen shoulder were highly satisfactory. However, sufficient care is required in explaining the method of administration and the adverse effects such as the osteonecrosis of the femoral head or osteoporosis.

Abstract
The patient was a 54-year-old woman who developed a right adrenal tumour, Cushingoid features, elevated levels of cortisol that were not suppressed by 1 nor 8 mg of dexamethasone, and suppression of adrenocorticotropin (ACTH) during treatment for severe hypertension. Computed tomography (CT) revealed a right adrenal tumour and an atrophic left adrenal gland. In addition, elevated plasma aldosterone concentration (PAC) and suppressed plasma renin activity (PRA) with an aldosterone-to-renin ratio of 128 (ng per 100 ml per ng ml–1 h−1) suggested aldosterone excess. Urinary excretion of aldosterone was relatively high, and the captopril and rapid ACTH tests resulted in no response of PRA and exaggerated increase in PAC, respectively. ACTH-loaded adrenal venous sampling showed bilateral excess of aldosterone with right predominance of cortisol. Right laparoscopic partial adrenalectomy (ADX) and immunohistochemical analysis showed both a cortisol-producing adenoma and an aldosterone-producing microadenoma (microAPA) within the attached adrenal, which had not been detected by CT preoperatively. After the right partial ADX, her blood pressure, aldosterone level and suppressed PRA remained unchanged. Subsequently, laparoscopic total left ADX was performed. Two microAPAs with paradoxical hyperplasia were revealed within the apparently atrophic left adrenal gland. Soon after the second surgery, her blood pressure normalized without requiring any anti-hypertensive medication.

Abstract
This study evaluated the pathology and therapeutic results of seven patients with intraosseous ganglia of the carpal bone. The mean age at the time of surgery was 27.6 years. The lesions were localized in the proximal carpal row in six patients and in the distal carpal row in only one. Surgical treatment was performed in all patients with good bone union. None had pain during activity or at rest and no recurrence had occurred. The intraosseous ganglia in four patients was of the idiopathic type, and in the other three patients was of the penetrating type. Although intraosseous ganglia of the carpal bone is reported as a rare disease, there were 159 cases in the literature. The pathology was intra- or extraosseous development, showing variation, but most cases were localized in the proximal carpal row.

Abstract
Pulsatile release of gonadotrophin-releasing hormone (GnRH) is indispensable to maintain normal gonadotrophin secretion. The pulsatile secretion of GnRH is associated with synchronised electrical activity in the mediobasal hypothalamus (i.e. multiple unit activity; MUA), which is considered to reflect the rhythmic oscillations in the activity of the neuronal network that drives pulsatile GnRH secretion. However, the cellular source of this ultradian rhythm in GnRH activity is unknown. Direct input from kisspeptin neurones in the arcuate nucleus (ARC) to GnRH cell bodies in the medial preoptic area or their terminals in the median eminence could be the intrinsic source for driving the GnRH pulse generator. To determine whether kisspeptin signalling could be responsible for producing pulsatile GnRH secretion, we studied goats, measured plasma levels of luteinising hormone (LH) and recorded MUA in the posterior ARC, where the majority of kisspeptin neuronal cell bodies are located. Rhythmic volleys of MUA were found to be accompanied by LH pulses with regular intervals in the ARC, where kisspeptin neuronal cell bodies were found. Exogenous administration of kisspeptin stimulated a sustained increase in LH secretion, without influencing MUA, suggesting that the GnRH pulse generator, as reflected by MUA, originated from outside of the network of GnRH neurones, and could plausibly reflect the pacemaker activity of kisspeptin neurones, whose projections reach the median eminence where GnRH fibres project. These observations suggest that the kisspeptin neurones in the ARC may be the intrinsic source of the GnRH pulse generator.

Abstract
Kisspeptin, a peptide encoded by the Kiss1 gene, has been considered as a potential candidate for a factor triggering the onset of puberty, and its expression in the hypothalamus was found to increase during peripubertal period in rodent models. The present study aimed to clarify the oestrogenic regulation of peripubertal changes in Kiss1 mRNA expression in the anteroventral periventricular nucleus (AVPV) and hypothalamic arcuate nucleus (ARC), and to determine which population of kisspeptin neurones shows a change in kisspeptin expression parallel to that in luteinising hormone (LH) pulses at the peripubertal period. Quantitative reverse transcriptase-polymerase chain reaction and immunohistochemistry revealed an apparent increase in the ARC Kiss1 mRNA expression and kisspeptin immunoreactivity around the time of vaginal opening in intact female rats. The AVPV Kiss1 mRNA levels also increased at day 26, but decreased at day 31, and then increased at day 36/41. In ovariectomised (OVX) rats, ARC Kiss1 mRNA expression did not show peripubertal changes and was kept at a high level throughout peripubertal periods. Apparent LH pulses were found in these prepubertal OVX rats. Oestradiol replacement suppressed ARC Kiss1 mRNA expression in OVX prepubertal rats, but not in adults. Similarly, LH pulses were suppressed by oestradiol in the prepubertal period (days 21 and 26), but regular pulses were found in adulthood. The present study suggests that a pubertal increase of Kiss1/kisspeptin expression both in the ARC and AVPV is involved in the onset of puberty. These results also suggest that both LH pulses and ARC Kiss1 expression are more negatively regulated by oestrogen in prepubertal female rats compared to adult rats.

Abstract
Acetylcholine (ACh) release in the dorsal hippocampus increases during stress, exploration or learning, exhibiting sex-specific 24-h release profile. We review the role of gonadal steroids on the ACh release in the dorsal hippocampus. In our studies, we found that male rats showed higher extracellular ACh levels than females, but gonadectomy decreased ACh levels in both sexes of rats and subsequently eliminated the sex difference. To examine the sex difference under comparable gonadal steroid levels, we implanted steroid capsules after gonadectomy. Oestradiol supplementation maintained circulating oestradiol to the levels in proestrous female rats, whereas testosterone capsules maintained circulating testosterone to the levels similar to intact male rats. Under comparable gonadal steroids levels, ACh levels were sex-specific. Testosterone replacement in orchidectomised rats clearly restored ACh levels, which were greater than ovariectomised testosterone-primed rats. Similarly, oestradiol replacement in ovariectomised rats successfully restored ACh levels, which were higher than orchidectomised oestradiol-primed rats. These results suggest sex-specific activational effects of gonadal steroids on ACh release. To further examine the organisational effect, female pups were neonatally treated with oil, testosterone, oestradiol, or dihydrotestosterone. These rats were bilaterally ovariectomised and a testosterone capsule was implanted at postnatal week 8. Neonatal treatment of either testosterone or oestradiol clearly increased ACh levels, whereas neonatal dihydrotestosterone treatment failed to change levels. These results suggest that: (i) gonadal steroids maintain the sex-specific ACh release in the dorsal hippocampus and (ii) neonatal activation of oestrogen receptors is sufficient to mediate masculinisation of the septo-hippocampal cholinergic system.

Abstract
High virus-neutralizing antibodies were induced in specific-pathogen-free breeding hens by administration of live and killed avian nephritis virus (ANV), strain M-8, antigens. Ten-day-old embryos from immune hens survived challenge by ANV which was administered by the yolk sac or allantoic cavity route. When the progeny chicks from immune dams were infected with ANV orally or by contact challenge, the virus replicated in the intestine. However, they were protected against pathological damage and virus replication in the kidney. The chicks without maternal antibodies showed apparent renal lesions and virus replication to high titre in the kidneys.

Abstract
It is often difficult to make a diagnosis of pleuritis associated with rheumatic diseases because of lack of specific diagnostic tools. We report a patient with lupus pleuritis from which tuberculous pleuritis was distinguished by Mycobacterium tuberculosis-specific enzyme-linked immunospot assay of pleural exudate mononuclear cells. After the diagnosis of lupus pleuritis, the patient was successfully treated with prednisolone.

Abstract
UNLABELLED Most patients who switched to a second bisphosphonate continued their treatment long term, although those who stopped their first drug because of adverse events were likely to discontinue the second drug for the same reason. Switching to another bisphosphonate is a reasonable treatment option for some patients with treatment failure. INTRODUCTION Patients who experience treatment failure with a bisphosphonate because of adverse events (AEs) or other reasons might receive a second bisphosphonate. However, the frequency and benefits of switching bisphosphonates are unknown. METHODS We retrospectively evaluated 197 men and 1110 women newly treated with bisphosphonates between 1 January 2000 and 30 June 2005 at our university hospital. RESULTS Among the 497 patients who discontinued bisphosphonate treatment, 146 were switched to a second bisphosphonate. The cumulative probabilities of persistence of treatment after 3 years were 45% with the first bisphosphonate and 65% with the second (P = 0.017). Age >or=65 years, switching bisphosphonates because of AEs, and male gender were associated (P < 0.05) with low persistence of treatment with the second bisphosphonate. Discontinuation of the first drug because of AEs was associated with an increased rate of discontinuation of the second drug because of AEs (hazard ratio, 4.2; 95% confidence interval, 2.1-8.4). CONCLUSIONS Patients who switched bisphosphonates had high rates of persistence of therapy. Those who stopped their first bisphosphonate because of AEs were at risk of discontinuing the second drug for the same reason. Switching to another bisphosphonate is a reasonable treatment option for some patients with treatment failure.

Abstract
Five cytopathic viruses morphologically resembling rotaviruses were isolated from duck faeces in chicken kidney cell cultures using conventional methods. One of the isolates, designated F-29 strain, was identified as an avian rotavirus from the following: ribonucleic acid in the viral core, virus growth in the cytoplasm, resistance to chloroform, acid and heating, partial stabilisation to molar magnesium chloride and rotavirus-like morphology by electron microscopy. By immunofluorescence, F-29 strain did not react with porcine and bovine rotaviruses. Neutralising antibodies to the F-29 strain were detected in sera collected from a conventional duck flock, but not from specific-pathogen-free duck flocks.

Abstract
Cytopathic viruses were isolated from the faeces, pancreas and caecal contents of broiler chicks in two cases of a stunting syndrome. Two representative strains, designated AAF7 and M-8, were identified as enteroviruses on the basis of their size (25 nm in diameter), RNA in the viral core, virus growth in the cytoplasm, resistance to chloroform, trypsin and acid, and partial heat-stabilisation to molar magnesium chloride. They formed irregular plaques in chick kidney cell cultures. Numerous granula eosinophilic inclusions were induced in the cytoplasm of chicken kidney cell cultures infected with the viruses. Both isolates reacted partially with the G4260 strain of avian nephritis virus but not with the VR strain of avian encephalomyelitis virus.

Abstract
In our institute, tacrolimus was started at a dose of 0.03 mg/kg/day and adjusted to maintain a blood concentration between 10 and 20 ng/mL combined with short term methotrexate after bone marrow transplantation from an unrelated donor. Dose adjustment was performed strictly, in order to prevent grade II-IV acute graft-versus-host disease (GVHD)while avoiding renal toxicity of tacrolimus. Then, in this study, we retrospectively evaluated the tacrolimus blood concentration during the first 4 weeks after transplantation. The mean tacrolimus concentration of the eligible 52 patients was 17.41+/-4.84(range, 9.5-33.4)ng/mL in the 1st week after transplantation, but declined to 13.7+/- 4.0(range, 8.1-25.6)ng/mL in the 2nd week. The dose of tacrolimus was decreased as follows: 0.022+/-0.005 mg/ kg/day(range 0.011-0.039)in the 1st week, and 0.018+/-0.007 mg/kg/day(range 0.004-0.040)in the 2nd week. The incidence of grade II-IV GVHD was 63.0% and grade III-IV was 13.9%. The individual variations of tacrolimus blood concentration did not affect the incidence of grade II-IV acute GVHD, as far as the concentration being maintained in the range of 14.82+/-4.22 ng/mL during the first 4 weeks after transplantation. In addition, the variations of tacrolimus concentration didn?t associate statistically with renal toxicity.

Abstract
We experimentally investigate the performance of a commercial tapered amplifier diode operating in a pulsed-current mode with a peak current that is significantly higher than the specified maximum continuous current. For a tapered amplifier rated at 500 mW of continuous power, we demonstrate 2.6 W of peak optical output power with 15 mW of injection light for 200 micros, 7 A current pulses. Different failure mechanisms for the tapered amplifier, including thermal and optical damage, are identified under these conditions.

Abstract
Follicular development and ovulation are suppressed during lactation in various mammalian species, mainly due to the suppression of pulsatile GnRH/LH secretion. Metastin (kisspeptin-54), a KiSS-1 gene product, is an endogenous ligand for GPR54, a G-protein-coupled receptor, and suggested to play a critical role in regulating the gonadal axis. The present study therefore aims to determine whether metastin (kisspeptin-54)-GPR54 signaling in discrete brain areas is inhibited by the suckling stimulus that causes suppression of LH secretion in lactating rats. Quantitative RT-PCR revealed that the KiSS-1 mRNA level was significantly lower in the arcuate nucleus (ARC)-median eminence region in lactating ovariectomized (OVX) and estrogen-treated OVX rats than in nonlactating controls. KiSS-1 mRNA in the anteroventral periventricular nucleus was kept at a low level in both lactating and nonlactating rats despite estrogen treatment. GPR54 mRNA levels were significantly lower in lactating than nonlactating rats in the anteroventral periventricular nucleus, but the levels in lactating mothers of the preoptic area and ARC-median eminence were comparable with nonlactating controls. Although KiSS-1 mRNA-expressing cells or metastin (kisspeptin-54) immunoreactivities were densely located in the ARC of nonlactating controls, few were found in the ARC of lactating OVX animals. Various doses of metastin (kisspeptin-54) (0.02, 0.2, and 2 nmol) injected into the third ventricle caused a significant increase in LH secretion in both lactating and nonlactating OVX rats, suggesting that lactating rats are responsive to metastin (kisspeptin-54) stimulus. Thus, the present study demonstrated that KiSS-1 mRNA/metastin (kisspeptin-54) expression is inhibited in the ARC by the suckling stimulus, suggesting that the inhibition is most probably involved in suppressing LH secretion in lactating rats.

Abstract
To investigate effects of the preautografting administration of rituximab on the mobilization and engraftment of peripheral blood stem cells (PBSC), we retrospectively analyzed the outcomes of 43 newly diagnosed diffuse-large B-cell lymphoma patients who received CHOP chemotherapy with or without rituximab as a first-line treatment before autologous PBSC transplantation (PBSCT). There was no difference in the number of CD34(+) cells among PBSC between the non-rituximab and the rituximab groups. Although B-cells were completely depleted from PBSC in the rituximab group, we found no difference in the expression of CXCR-4, VLA-4 and c-Kit on PBSC, indicating that rituximab did not affect the expression of these adhesion molecules, which might be involved in the mechanism of mobilization. There was no significant difference in the recovery of neutrophils and platelets, transplant-related toxicity and post-transplant complications between the two groups. Despite the short follow-up, there was no significant difference in progression-free survival between the two groups. These results indicated no adverse effect of rituximab on the mobilization and engraftment of PBSC. Larger studies are required to determine the impact of rituximab on the mobilization and function of PBSC as well as whether a survival advantage exists in patients who undergo auto-PBSCT with rituximab.
