Abstract
Preclinical studies have demonstrated the synergistic anti-tumour activity of combination therapy with the oral cytostatics, 5′-deoxy-5-fluorouridine (5′-DFUR) and cyclophosphamide (CPA), in human breast cancer xenograft models. This study was performed to evaluate the efficacy and safety of this oral combination chemotherapy in the treatment of metastatic breast cancer. In all, 101 patients with metastatic breast cancer were enrolled in the study, and the data for 94 eligible patients of these were evaluated. The patients received twice daily oral combinations of 5′-DFUR (1200 mg/body/day) and CPA (100 mg/body/day) for 2 weeks, followed by a 1-week rest period. After a median of 19 treatment cycles (range 1–66 cycles), 16 patients (17.0%) had a complete response, and 40 patients (42.6%) had partial responses. The response rate was 59.6% (95% CI, 49.0–69.6%). The median time to progression and overall survival times were 11.7 and 40.3 months, respectively. The toxicity was mild and tolerable, and the related grade 3/4 clinical adverse effects consisted of haematological toxicity in 21 patients (22%) and nonhaematological toxicity in five patients (5%). These results suggest that the oral combination chemotherapy of 5′-DFUR and CPA has low toxicity and is a novel, very convenient and effective treatment for metastatic breast cancer.

Abstract
BACKGROUND Breast cancer has been the subject of many recent studies because it is a significant cause of death in women. This study was performed to clarify whether solitary skeletal metastasis has clinical significance compared with multiple skeletal metastasis. PATIENTS AND METHODS Seven hundred and three patients who developed metastatic bone lesions up to September 2002 after beginning treatment for breast cancer from 1988 to 1998 were included. The lesions were classified first as solitary or multiple based on bone scan results and then according to anatomical distribution. Next, solitary-to-multiple conversion was investigated in patients with solitary skeletal metastasis. Then factors related to solitary or multiple skeletal metastasis were analyzed. The prognosis of skeletal metastasis was compared between patients with solitary or multiple metastatic bone lesions. A Cox proportional hazards model was used to test whether solitary skeletal metastasis compared with multiple skeletal metastasis was an independent factor of survival. RESULTS Two hundred and eighty-nine patients (41%) had solitary skeletal metastasis and 414 patients (59%) showed multiple skeletal metastasis. The sternum was a frequent site for solitary skeletal metastasis (98 of 289, 34%), while other skeletal sites were more frequent in patients with multiple metastatic bone lesions (P <0.001). Solitary sternal metastatic lesions remained solitary longer than solitary metastatic bone lesions to places other than the sternum (P <0.001), but did not lengthen patient survival times (P = 0.871). The factors related to solitary skeletal metastasis are TNM stage (tumor-node-metastasis) and histology. The patients with earlier stage and favorable histology tend to have solitary skeletal metastasis. The patients with solitary skeletal metastasis lived longer than those with multiple metastatic bone lesions (P <0.001). Multivariate analysis revealed that a solitary metastatic bone lesion (P = 0.002) is an independent favorable prognostic factor in patients with skeletal metastasis. CONCLUSIONS Solitary skeletal metastasis has a different anatomical distribution and is an independent prognostic factor in patients with skeletal metastasis.

Abstract
Fiber connections of the torus longitudinalis (TL) and target(s) of toral recipient tectal neurons (pyramidal cells) in the optic tectum were examined by tract-tracing methods in holocentrids. Injections into the stratum marginale (SM) labeled neurons in the stratum opticum and stratum fibrosum et griseum superficiale (SFGS). They had superficial spiny dendrites, with a fan-shaped branching pattern in SM and a thick basal dendrite that gave rise to bushy horizontal branches at the boundary between the SFGS and the stratum griseum centrale (SGC), where an axon and a thin dendrite arose. The axon terminated in a middle cellular layer of the SGC, and the thin dendrite ramified slightly deeper to this cellular layer. The SM injections also labeled cells in the ipsilateral TL. Injections into either the lateral or the medial part of TL labeled terminals in the ipsilateral SM and neurons in the bilateral nucleus paracommissuralis (NPC) and nucleus subvalvularis and ipsilateral nucleus subeminentialis. Only medial TL injections labeled cells in the ipsilateral SGC. These neurons had a basal dendrite that branched in the middle cellular layer of SGC, suggesting that they receive inputs from the pyramidal cells and project back to the TL to form a closed circuit. Only lateral TL injections labeled terminals in the corpus cerebelli. A visual telencephalic portion projects to the NPC and sublayers of SGC, where dendrites of the pyramidal cells and SGC neurons ramify. The present results therefore suggest that the TL and SM are components of an intricate circuitry that exerts telencephalic descending visual influence on the optic tectum and corpus cerebelli.

Abstract
The nucleus paracommissuralis (NPC) of teleosts is a relay nucleus of an indirect telencephalo-cerebellar pathway. However, cells of origin in telencephalic subdivisions and terminal patterns of the NPC fibers in the cerebellum remain unclear. We studied these issues by means of tract-tracing methods in a cichlid, tilapia (Oreochromis niloticus). After tracer injections into the NPC, retrogradely labeled cells were found bilaterally in dorsal and ventral regions of the area dorsalis telencephali pars centralis (dDc and vDc) and area dorsalis telencephali pars dorsalis (Dd). Anterogradely labeled terminals were found in a caudal part of the bilateral corpus cerebelli (CC). The labeled terminals were restricted in the granular layer, which can be divided into dorsal and ventral regions based on cytoarchitecture. We injected tracers separately into the three telencephalic portions (dDc, vDc, and Dd) and into the dorsal or ventral regions of granular layer in the caudal CC. The results revealed a topographical organization of the indirect telencephalo-cerebellar pathway. A medial portion of the NPC received fibers from the vDc and projected to the ventral region of the caudal CC. An intermediate portion of the NPC received fibers from the dDc and Dd, and in turn projected to the dorsal region of the caudal CC. A lateral portion of the NPC received fibers from the Dd and in turn projected to the dorsal region of the caudal CC. The Dc is known to receive visual input via the area dorsalis telencephali pars lateralis, and the Dd is presumably a multimodal telencephalic portion. The present study suggests that the indirect telencephalo-cerebellar pathway through the NPC might convey descending visual and multimodal information to the CC in a topographical manner. We also demonstrated other indirect telencephalo-cerebellar pathways through the nucleus lateralis valvulae and the area pretectalis.

Abstract
Sentinel node (SN) biopsy is a promising replacement for standard axillary lymph node dissection for the staging of early breast cancer, and various techniques have been studied to identify SNs with dye or radioactive colloid. This study assesses the effect of the dose of radioactivity and the time before biopsy in order to set standards for the use of 99mTc-rhenium sulphide for the detection of SNs in breast cancer patients. Sixty patients with stage T1-2 N0 M0 breast cancer underwent SN biopsy, which was immediately followed by standard axillary dissection to confirm the SN results. For SN biopsy, 99mTc-rhenium colloid was injected peritumorally. A 1 day (morning injection and afternoon surgery) or 2 day (day before afternoon injection and morning surgery) protocol was applied. A dose-finding study was performed simultaneously using 7.4-37 MBq for the 1 day protocol and 37-74 MBq for the 2 day protocol. A scintigram was taken at 2 h for the 1 day protocol and 16 h for the 2 day protocol. After the injection of blue dye, SN biopsy was performed with a gamma probe, followed by standard axillary node dissection. The radiation exposure received by the surgical team during the operation was monitored. Histopathological comparison between SNs and axillary nodes was performed. Patient characteristics that might affect the radiocolloid uptake by SNs were assessed. SNs were identified in all patients regardless of the dose or administration protocol used. Two patients showed false negative pathological SN results, and the negative predictive value was 96% and the positive predictive value was 100%. In addition, radiation exposure to the surgical team and the amount of radioactive surgical waste were low, especially at lower doses. Two groups of patient characteristics were related to SN uptake. One was the body mass index (BMI) and the other was the age or menopausal status. Patients with a larger BMI tended to take up a smaller amount of 99mTc colloid. Older or post-menopausal patients showed lower SN uptake. 99mTc-rhenium sulphide colloid is an efficient radiopharmaceutical for SN detection. Both 1 day and 2 day protocols have equally good efficacy, and the recommended dose is 7.4 MBq for the 1 day protocol and 37 MBq for the 2 day protocol. Patients with larger BMI and older or post-menopausal patients tend to take up less 99mTc colloid.

Abstract
Radiotherapy (RT) is not always necessary for the prevention of ipsilateral breast recurrence in cases where cancer is not detected in the remaining breast tissue after breast conserving surgery. In addition, under these circumstances, the rate of a second primary cancer of the remaining breast is theoretically equal to the rate of contralateral breast cancer. In performing breast conserving treatment (BCT) at our institution we do not treat with RT if a strict serial pathological examination of the specimen (every 5 mm) reveals that the case has been safely resected (negative surgical margins). From 1986 to 1998, 827 patients (157 were ductal carcinoma in situ, and 670 were invasive) underwent BCT without RT at the Cancer Institute Hospital. Ipsilateral breast cancer was observed in 46 cases or 5.6% (0.85% annually) during a median observation period of 67 months. Of these 46 cases, 19 (2.3%) were diagnosed as a recurrence and 27 cases (3.3%) were second primary cancers. This recurrence rate is equivalent to the rate observed in 406 cases of BCT (1.7%) that were treated with RT. Most of these cases had shown positive surgical margins. Furthermore, the rate of occurrence of second cancers is not significantly different from the rate of occurrence of contralateral breast cancers. These results suggest that, by selecting irradiation cases based on careful pathological examinations, BCT can be safely performed.

Abstract
Fiber connections of the carp torus longitudinalis were re-examined by means of tract-tracing methods. The torus longitudinalis projected mainly to the stratum marginale of the optic tectum, area pretectalis, and corpus cerebelli. The stratum marginale was anterogradely labeled only by biocytin, but not by horseradish peroxidase. Because the stratum is composed of extremely fine axons of the small toral neurons, this may be ascribed to different molecular weights of the tracers. The main afferent sources to the torus longitudinalis were the nucleus subvalvularis, which was located beneath the nucleus lateralis valvulae, the nucleus subeminentialis pars magnocellularis, and neurons along the posterior mesencephalo-cerebellar tract. Some labeled cells also appeared in the area pretectalis, nucleus paracommissuralis, optic tectum, and torus semicircularis. In a previous paper, it was incorrectly reported that the valvula cerebelli was the main source of afferents to the torus longitudinalis. Here we report the reason for the previous mistake in relation to the techniques employed.

Abstract
A Free Air CO2 Enrichment (FACE) system for rice and winter wheat rotation was established, elevated CO2 concentration was controlled to 200 mumol.mol-1 above ambient by computer system platform according to ambient CO2 concentration variation, wind direction, wind speed, canopy height and day-night changing. Experiments showed that the main factors affecting control precision are wind speed, crop and soil respiration and thickness of diffuse layer. After parameters adjustment, in daytime the time fraction for control precision achieve 80% is 83%, in night is 68%. The CO2 concentrations distribution in FACE rings are uniformity. The set CO2 is 557 mol.mol-1 in daytime and 608 mol.mol-1 in night. In 2001 rice season the target achievement ratios (TAR) were 1.03 after sunrise and 1.09 after sunset, respectively.

Abstract
The nucleus pretectalis (NP) is a prominent nucleus in the percomorph pretectum and has been shown to project to the nucleus isthmi in the filefish by an HRP tract-tracing method [Ito et al., 1981], but a homologous nucleus to the NP is apparently lacking in ostariophysans. The present study examined fiber connections of the nucleus isthmi in an ostariophysan teleost, the carp (Cyprinidae, Cyprinus carpio), to identify a nucleus homologous to the percomorph nucleus pretectalis. Identical studies in a percomorph tilapia (Cichlidae, Oreochromis niloticus) were also performed. Injections of biotinylated dextran amine (BDA) or biocytin to the carp nucleus isthmi labeled cells in the ipsilateral optic tectum and nucleus ruber of Goldstein [1905]. Labeled tectal neurons were located in the stratum periventriculare (SPV) and the stratum fibrosum et griseum superficiale (SFGS). The somata in the SPV were pyriform and those in the SFGS were fusiform. No labeled cells were found in the pretectum. Labeled terminals were seen in the ipsilateral nucleus pretectalis superficialis pars parvocellularis (PSp), optic tectum, and bilateral nucleus ruber. Terminals in the nucleus ruber appear to come from tectal neurons in the SFGS labeled by isthmic injections. Thus the nucleus isthmi has reciprocal fiber connections with the ipsilateral optic tectum, receives projections from the ipsilateral nucleus ruber, and projects to the ipsilateral PSp. The nucleus pretectalis homologue is apparently absent in the carp. Studies in tilapia showed that the nucleus isthmi receives bilateral projections from the NP and optic tectum. In addition, the present study revealed a previously unknown afferent from the nucleus ruber to the percomorph nucleus isthmi. The tilapia nucleus isthmi projects to the same targets as in the carp. Isthmic projection neurons in the tilapia optic tectum were located in the SPV and pyriform with a similar shape to the carp SPV neurons that project to the nucleus isthmi. No labeled cells were found in the SFGS of tilapia optic tectum. The fusiform neurons in the SFGS of the carp optic tectum possess various hodological similarities with the NP and may correspond to the NP neurons of percomorphs.

Abstract
Eye development and brain structures of a mutant teleost fish were investigated. The el (eyeless) mutation in medaka (Oryzias latipes) is recessive and affects eye formation; in the most severe cases, it results in the absence of eyes. Developmental studies revealed that normal eyeballs are not formed in the el mutant embryos, but small optic cup-like structures differentiate in situ in the walls of the prosencephalon without evagination. The anophthalmic el homozygous fish hatched normally, although they did not respond behaviorally to visual stimuli. A small fraction of these fish grew to adulthood. In the adult anophthalmic el homozygous fish, the brain exhibited abnormalities in several subdivisions. A pair of small abnormal protrusions was observed on the surface of the ventral telencephalon and preoptic area. Immunocytochemistry using a rhodopsin monoclonal antibody showed that opsin-positive cells were present in the abnormal structures. Bodian staining showed that the optic nerves were present near the abnormal structures, although the number of optic nerve fibers was extremely small. The optic tectum was extremely small, and the thickness of the stratum opticum and stratum fibrosum et griseum superficiale was reduced. These behavioral and morphological observations suggest that the adult anophthalmic el homozygous fish are functionally blind, although small retina-like structures were partially differentiated and persisted in the adult fish brain. Moreover, the adult anophthalmic el homozygous fish were infertile, and the sizes of the hypophysis and the hypothalamus were reduced. Thus, the el mutation affects not only the brain structures that are related to the visual system but also those related to the reproductive system.

Abstract
Seven-day-old rat brain slices were incubated at 36C in oxygenated Krebs-Ringer solution containing [(18)F]2-fluoro-2-deoxy-D-glucose ([(18)F]FDG), and serial two-dimensional time-resolved images of [(18)F]FDG uptake by the slices were obtained. The Gjedde-Patlak graphical method was applied to the image data, and the duration limit of hypoxia loading that allowed recovery of the fractional rate constant (k3*) of [(18)F]FDG (proportional to the cerebral glucose metabolic rate) after hypoxia loading to the unloaded control level was 50 min, and MK-801 as an N-methyl-D-aspartate antagonist had neuroprotective effects, but PBN as a free radical scavenger was ineffective. In our previous study in adult (7-week-old) rat brains [Murata et al., Exp Neurol 2000, 164:269-279], the limit of the hypoxia loading time was 20 min, and both MK-801 and PBN were effective. In the immature rat brains, the ratio of aerobic glucose metabolism to the total glucose metabolism was low compared with the adult rat brains, suggesting only a slight involvement of free radicals in hypoxic neurotoxicity. These data suggest that the higher resistance of immature brains to hypoxia compared to that of adult brains is attributable to a lower involvement of free radicals due to a lower aerobic glucose metabolic rate.

METHODS Case report and review of the literature. RESULTS While taking steroids and antibiotics, a 52-year-old man with uveitis associated with cat-scratch disease developed retinal vein occlusion and a macular exudate. His final visual acuity was poor because of residual macular degeneration and optic atrophy. Serum C-ANCA increased and decreased in parallel with ocular inflammatory activity. CONCLUSION C-ANCA is an indicator of vasculitis and may be useful as an indicator of severe cat-scratch disease.

Abstract
The first choice of therapy for nephrotic syndrome is steroid, and cyclosporin A(CyA) or other immunosuppressants are selected for steroid resistant or recurrent cases. Nephrotic syndrome accompanies hyperlipidemia for which HMG-CoA reductase inhibitors are mainly used. On the other hand, probucol is used in cases showing inadequate effects or some adverse reactions under treatment with HMG-CoA reductase inhibitors. Recently, we experienced several cases whose blood levels of CyA were decreased to about half that before the combined use of probucol, and concomitant administrations were discontinued. Based on these cases, we considered that the use of probucol should be prescribed in patients with nephrotic syndrome accompanying hyperlipidemia giving preference to CyA treatment. In cases of unavoidable usage of probucol, CyA dose adjustments are required on the basis of frequent CyA blood level monitoring.

Abstract
Mutations in the transcription factor hepatocyte nuclear factor-1alpha (HNF-1alpha; gene symbol TCF1) cause maturity-onset diabetes of the young type 3 (MODY3), a form of diabetes mellitus characterized by autosomal dominant inheritance, early onset, and pancreatic beta-cell dysfunction. Recent genetic studies, however, also found mutations in patients diagnosed with idiopathic (non-autoimmune based) type 1 diabetes. We identified a novel frameshift mutation (142delG) in the TCF1 gene in a family with a strong family history of type 1 diabetes and examined the functional properties of the mutant HNF 1alpha. The expression of the mutant protein was not detected in COS-7 cells by Western blot analysis after transfection of the mutant cDNA. This is the first case of an unstable mutant HNF-1alpha protein. Reporter gene analysis indicated that the mutant HNF-1alpha had no transactivation activity in HeLa and MIN6 cells. Haploinsufficiency for HNF-1alpha may lead to severe forms of diabetes like type 1 diabetes.
