Abstract
Malignant mesothelioma (MM) is uncommon in cats and dogs and can be challenging to diagnose. Adequate tissue sampling is required for superior diagnostic accuracy. Protoporphyrin IX, a metabolite of 5-aminolaevulinic acid (5-ALA), is a photosensitiser for photodynamic diagnosis (PDD). To the best of our knowledge, no study has reported the use of 5-ALA-PDD to detect MM in veterinary medicine. The present study describes the use of 5-ALA-PDD for MM diagnosis in a cat and dog, as well as the effectiveness of intracavitary chemotherapy. We evaluated the use of PDD with 5-ALA hydrochloride (5-ALA-PDD) in two cases of MM. A 12-year-old cat presented with a 1-month history of respiratory distress, and a 9-year-old dog presented with a 3-month history of mild abdominal distention. We endoscopically biopsied lesions in both the cases using 5-ALA-PDD. Histopathological examination revealed mesothelioma, and immunohistochemical staining was positive for calretinin. Both patients were treated with carboplatin. The cat died of respiratory failure. Although, the dog's condition improved 21 days after the first chemotherapeutic drug administration, the dog died on day 684 owing to cardiac-related issues. 5-ALA-PDD is thus, safe and feasible for the diagnosis of MM in veterinary medicine.

Abstract
We demonstrate 1 GHz count rate photon detection with photon number resolution by using a multi-pixel photon counter (MPPC) and performing baseline correction. A bare MPPC chip mounted on a high-frequency circuit board is employed to increase response speed. The photon number resolving capability is investigated at high repetition rates. This capability remains at a repetition rate of 1 GHz and at rates as high as an average of 2.6 photons detected per optical pulse. The photon detection efficiencies are 16% at λ = 450 nm and 4.5% at λ = 775 nm with a dark count rate of 270 kcps and an afterpulse probability of 0.007.

Abstract
Multipixel silicon avalanche photodiodes (Si APDs) are novel photodetectors used as silicon photomultipliers (SiPMs), or multipixel photon counter (MPPC), because they have fast response, photon-number resolution, and a high count rate; one drawback, however, is the high dark count rate. We developed a system for cooling an MPPC to liquid nitrogen temperature and thus reduce the dark count rate. Our system achieved dark count rates of <0.2 cps. Here we present the afterpulse probability, counting capability, timing jitter, and photon-number resolution of our system at 78.5 K and 295 K.

Abstract
e16558 Background: Recently, the number of young patients with invasive uterine cervical carcinoma is increasing in Japan because of earlier sexual activity and low rate of receiving screening test of uterine cervical carcinoma in Japan. However, no large studies have been performed so far to evaluate the clinical outcomes of curative intended radiation therapy for young patients with invasive uterine cervical carcinoma in Japan. Then, the current study was designed. Methods: One hundred and five patients under 40 years old were registered in the mulitiinstitutional study. The median age was 34.5 years old (range: 24–39 years old). According to FIGO, clinical stage was as follows. Stage Ib/IIa/IIb/IIIa/IIIb/IVa were 10/4/38/2/47/3, respectively. The median maximal tumor diameter was 5.5 cm (range: 2–9.2 cm). Curative intended radiation therapy was the combination of high-dose rate intracavitary brachytherapy (HDR-ICBT) combined with external beam radiation therapy (ERT). The total dose of ERT ranged from 44 Gy to 68 Gy. The total dose of HDR-ICBT to point A ranged from 12 Gy to 48 Gy. Eighty five patients received chemotherapy. Results: The 5-year overall survival rate and local control rate of all patients was 58.4 % and 59.3 %, respectively. The 5-year overall survival rates of stage Ib/IIa/IIb/IIIa/IIIb/IVa were 90.0 %/not available (NA)/73.8%/100%/37.4%/0%, respectively. The 5-year local control rates of Stage Ib/IIa/IIb/IIIa/IIIb/IVa were 80.0 %/50.0 %/73.8 %/100 %/54.6 %/NA, respectively. Sixteen patients experienced grade 3 or greater late radiation morbidity. Conclusions: Clinical outcomes of stage I-II in the young were equivalent to the Japanese standard treatment results of all ages. However, clinical outcomes of stage IIIb and IVa in the young were worse than those of all ages (5-year OS of all ages in Japan: IIIb: 50 %, IVa: 25 %). No significant financial relationships to disclose.

Abstract
PURPOSE To establish dosimetric predictors of radiation esophagitis (RE) in patients treated with a combination of carboplatin, paclitaxel, and radiotherapy. METHODS AND MATERIALS Three-dimensional radiotherapy plans of 26 patients with non-small-cell lung cancer who received 50-60 Gy of radiotherapy concurrently with weekly administration of carboplatin (AUC 2) and paclitaxel (40-45 mg/m(2)) were reviewed in conjunction with RE. The factors analyzed included the following: percentages of organ volumes receiving >40 Gy (V40), >45 Gy (V45), >50 Gy (V50), and >55 Gy (V55); the length of esophagus (total circumference) treated with >40 Gy (LETT40), >45 Gy (LETT45), >50 Gy (LETT50), and >55 Gy (LETT55); the maximum dose in the esophagus (Dmax); and the mean dose in the esophagus (Dmean). Data were obtained on the basis of superposition algorithm. RESULTS All factors except Dmax showed statistical correlation with RE. Good correlations were shown between RE and LETT45 (rho = 0.714) and V45 (rho = 0.686). CONCLUSIONS LETT45 and V45 appear to be useful dosimetric predictors of RE. It is also suggested that Dmax does not predict RE.

Abstract
We studied the serological cross-reactions among Bartonella henselae, Chlamydia pneumoniae and Coxiella burnetii by indirect fluorescence antibody (IFA) method, using sera from 8 patients with cat scratch disease (CSD), 13 patients with C. pneumoniae infection and 12 patients with acute Q fever. B. henselae IgG antibody was negative in 13 patients with C. pneumoniae infection, and was positive in 3 (titers being 1:64) of 12 patients with Q fever, whereas B. henselae IgM antibody was negative in all the patients with C. pneumoniae infection or Q fever. C. burnetii IgG antibody was removed by absorption of these 3 sera with C. burnetii antigens, whereas B. henselae IgG antibody did not change. C. pneumoniae IgG antibody was positive in 3 (titers being 1:125 in two, 1:32 in one) of 8 patients with CSD. Both C. pneumoniae and B. henselae IgG antibody titers were significantly reduced by absorption of these 3 sera with B. henselae antigens. C. burnetii IgG or IgM antibodies were negative in all patients with CSD. In conclusion, no serological cross-reaction between B. henselae and C. burnetii was observed. On the other hand. B. henselae IgG antibody cross-reacted to C. pneumoniae antigens, whereas C. pneumoniae IgG antibody did not cross-react to B. henselae antigens. Our findings suggest that determination of B. henselae IgG or IgM antibodies were not influenced by C. pneumoniae and C. burnetii antigens.

Abstract
BACKGROUND AND PURPOSE The incidence and extent of radiation esophagitis were assessed endoscopically in patients treated with concurrent chemoradiotherapy. PATIENTS AND METHODS Eighty-two patients who received thoracic radiotherapy for lung, thymic, or esophageal cancer were investigated endoscopically from July 1991 to the end of 1997. Among them, 23 esophageal cancer patients were treated with radiation alone, and the others were treated with concurrent chemoradiotherapy. Esophageal endoscopy was performed during or just after radiotherapy. The presence of radiation esophagitis was assessed and assigned an endoscopic score (i.e. grade 0 for normal, 1 for erythema, 2 for erosion or sloughing, 3 for ulcer, hemorrhage, or stricture). The symptomatic grade was assessed using the RTOG (Radiation Therapy Oncology Group) acute radiation morbidity score. RESULTS A correlation was seen between endoscopic and RTOG scores. However, even some patients with RTOG grade 0 to 1 had endoscopic grade 3 esophagitis. Endoscopic grade 3 was observed in 16 (27.1%) patients in the concurrent chemoradiotherapy group, whereas it did not occur in any patient in the radiation alone group (P=0.004). CONCLUSIONS Our results suggest that (1) RTOG score correlates closely to esophageal mucosal damage, and (2) more severe esophagitis occurs in those undergoing concurrent chemoradiotherapy than those undergoing radiotherapy alone [corrected].

Abstract
PURPOSE To evaluate the outcomes of orbital irradiation with or without high-dose or pulsed corticosteroids in patients with Graves' ophthalmopathy (GO). METHODS AND MATERIALS One hundred and twenty-one patients with moderate to severe GO who received orbital irradiation from 1987 to 1997 were retrospectively analyzed. A total dose of 20 Gy in 10 fractions was delivered to the bilateral retrobulbar volume. Eighty-six patients were treated in combination with high-dose or pulsed corticosteroids and irradiation. Univariate and multivariate analyses were performed to assess the prognostic variables. RESULTS The median follow-up period was 26 months. The overall clinical response was evaluated as excellent in 17 patients (14%), good in 65 (54%), fair in 31 (25%), no response in 7 (6%), and worse in 1 (1%). The best responses were noted for soft-tissue signs, extraocular muscle involvement, and sight loss, while a limited response was noted for proptosis. Multivariate analysis revealed that the use of high-dose corticosteroid or pulsed corticosteroids, female gender, and a shorter duration of ophthalmopathy before radiotherapy were significantly correlated with favorable outcomes. No long-term complications related to radiotherapy were observed. CONCLUSION Orbital irradiation combined with high-dose or pulsed corticosteroids is an effective treatment for moderate to severe GO, especially in cases with major manifestations of soft-tissue signs, extraocular muscle impairment, or sight loss.

Abstract
Surgical management of unerupted teeth depends upon a thorough understanding of anatomic, physiologic and pathologic factors. Attention has been given to problems of eruption in the maxillary anterior region. It is a region where a variety of anomalies occur. Since the maxillary anterior region influences appearance so greatly, early detection of difficulties and careful planning and treatment can be extremely beneficial to patients. The purpose of this case report is to present a case of maxillary permanent canine impaction in a horizontal displacement that developed after loss of the deciduous canine to chronic apical periodontitis, and incomplete root resorption of the deciduous canine.

Abstract
PURPOSE Recent studies have revealed that ionizing radiation induces the expression of intercellular adhesion molecule-1 (ICAM-1), vascular cell adhesion molecule-1 (VCAM-1), and P-selectin in vitro. The purpose of this study was to investigate the expression of these adhesion molecules in mouse lung following whole thoracic irradiation. MATERIALS AND METHODS C57BL/6J mice were irradiated with a single dose of 12 Gy to the thoraces and sacrificed at 4, 12, 24, and 48 hours and 1, 2, 4, and 8 weeks after irradiation. Expression of total lung mRNA for ICAM-1, VCAM-1, and P-selectin was quantified by the Northern blot method and normalized to beta-actin. RESULTS There were increases in mRNA for ICAM-1 of 42% at 4 hours (p < 0.05), 76% at 24 hours (p < 0.01), and 51% at 48 hours (p < 0.05) compared with the controls. These returned to the control level at 1 week. The expression of VCAM-1 mRNA was also increased by 49% (p < 0.01) at 12 hours and was still increased by 25% at 1 week. P-selectin mRNA was transiently increased by 59% at 12 hours. CONCLUSIONS These early inductions of mRNA for ICAM-1, VCAM-1, and P-selectin in mouse lung following thoracic irradiation were transient but significant, and are one of the most immediate changes reported in vivo.

Abstract
The inbred mutant strains of Long-Evans Cinnamon (LEC) rats spontaneously develops acute hepatitis as a result of abnormal copper accumulation, followed by chronic hepatitis, cholangiofibrosis and hepatocellular carcinoma. To shed some light on the role of macrophages in the liver failure, immunohistochemical methods were used to investigate the kinetics of macrophage populations in the liver of male LEC rats, in relation to the appearance of myofibroblastic cells and hepatocyte apoptosis. Rats examined at 24 weeks of age and moribund rats killed at 22-25 weeks of age had increased serum concentrations of aspartate aminotransferase and alanine aminotransferase, with jaundice and histological changes indicative of hepatic failure, whereas rats examined at 8, 12, 16 or 20 weeks old showed no such abnormal findings. Immunolabelling with ED1 (a monoclonal antibody recognizing rat macrophages) and ED2 (a monoclonal antibody specific for rat resident macrophages) revealed that numbers of blood monocyte-derived macrophages and Kupffer cells began to increase markedly at 16 weeks of age (before the onset of hepatitis). However, alpha-smooth muscle actin (SMA)-positive myofibroblastic cells (modulated perisinusoidal cells) and hepatocyte apoptosis, demonstrable by the TUNEL method, were rarely seen at 8, 12, 16, 20 or 24 weeks. There was no close relationship between macrophage expansion and the appearance of myofibroblastic cells or hepatocyte apoptosis. In moribund rats, only a few SMA-positive cells were seen in the periportal zones; hepatocytes undergoing apoptosis increased in number, and macrophages engulfing apoptotic bodies were observed occasionally, suggesting that apoptosis was related to hepatic failure as an early event. In addition, immunohistochemical examination demonstrated abnormal deposits of laminin along the sinusoids from 20 weeks, as an initial extracellular matrix protein in LEC rat livers.

Abstract
The mi locus encodes a member of the basic-helix-loop-helix-leucine zipper (bHLH-Zip) protein family of transcription factors (hereafter called MITF). We reported that expression of the mouse mast cell protease 5 (MMCP-5) and MMCP-6 genes were deficient in cultured mast cells (CMC) derived from mutant mice of mi/mi genotype. Despite the reduced expression of both MMCP-5 and MMCP-6, their regulation mechanisms were different. Because MMCP-5 is a chymase and MMCP-6 a tryptase, there was a possibility that the difference in regulation mechanisms was associated with their different characteristics as proteases. We compared the regulation mechanisms of another chymase, MMCP-4, with those of MMCP-5 and MMCP-6. The expression of the MMCP-4 gene was also deficient in mi/mi CMC. The overexpression of the normal (+) MITF but not of mi-MITF normalized the poor expression of the MMCP-4 gene in mi/mi CMC, indicating the involvement of +-MITF in transactivation of the MMCP-4 gene. Although MMCP-4 is chymase as MMCP-5, the regulation of MMCP-4 expression was more similar to MMCP-6 than to MMCP-5. We also showed the deficient expression of granzyme B and cathepsin G genes in mi/mi CMC. Genes encoding granzyme B, cathepsin G, MMCP-4, and MMCP-5 are located on chromosome 14. Because all these genes showed deficient expression in mi/mi CMC, there is a possibility that MITF might regulate the expression of these genes through a locus control region.

Abstract
Tumours of uterine smooth muscle are poorly understood neoplasms in which the effects of steroid sex hormones are complex. The influence of progesterone and oestrogen on a transplantable rat uterine smooth muscle tumour line (SMT-Y) was investigated. Female F344 rats given subcutaneous transplants of tumour fragments developed tumours, 1.5-2 cm in diameter, and were then treated with progesterone (10 mg/rat) or 17 beta-oestradiol (50 mg/rat). Tumours in treated groups were compared with those in untreated controls. During a 9-week observation period after treatment, progesterone promoted tumour growth from 4 weeks, with increased numbers of proliferating cells. In contrast, oestradiol inhibited tumour growth from 6 weeks; the degraded tumours, consisting mainly of vacuolated neoplastic cells, had decreased numbers of proliferating cells and increased numbers of apoptotic cells, demonstrable by in-situ terminal deoxyribonucleotide transferase (TdT)-mediated dUTP nick labelling. Immunohistochemically, tumours in control and progesterone groups were labelled positively for alpha-smooth muscle actin (SMA) and desmin but not for vimentin, whereas the degraded tumours in the oestradiol group had reduced reactivity for SMA and desmin but an increased reactivity for vimentin. These results indicate that progesterone may act as a promoter for uterine smooth muscle tumour growth by stimulating mitotic activity, whereas oestrogen may have suppressive effects on tumour growth, accompanied by morphological changes.

Abstract
Mouse mast cell protease (MMCP) mRNA expression was examined by in situ hybridization histochemistry. Peritoneal mast cells (PMCs) of WBB6F1-(+/+) mice expressed MMCP-2, MMCP-4, MMCP-5, and MMCP-6 mRNAs, but did not express MMCP-1 mRNA. When proliferation of PMCs was induced by culturing them in methylcellulose with T cell-derived cytokines, cells in mast cell colonies expressed MMCP-1 mRNA. These mast cells were transferred to a suspension culture to induce further proliferation. The phenotype of the resulting PMC-derived cultured mast cells was similar to that of bone marrow-derived cultured mast cells. When 10(5) PMC-derived cultured mast cells or 10(5) bone marrow-derived cultured mast cells were injected into the stomach wall of mast cell-deficient WBB6F1-W/Wv mice, mast cells that appeared in the mucosa and muscularis propria were similar to mast cells in the stomach of intact WBB6F1-(+/+) mice, indicating the injected cells adapted to a new tissue environment. In contrast, when 10(5) PMCs were injected into the stomach wall of WBB6F1-W/Wv mice, the injected PMCs did not adapt to the mucosa. When 20 PMCs were injected, they proliferated and adapted to the mucosal environment. The present results suggest that PMCs adapt to new environments when proliferation occurs before redifferentiation.

Abstract
The purpose of this study was to evaluate the longitudinal changes in arch width from childhood to adolescence. The subjects were 28 persons (13 males and 15 females) with untreated normal occlusion. Dental casts were taken at bimonthly intervals from childhood to adolescence. These materials were measured; the changes in the dental arch were compared on the basis of the status of the tooth emergence of certain permanent teeth and also on the chronological age from 3 years to 20 years of age. In the maxilla and mandibula, the width between the deciduous canines, the width between the first deciduous molars, and the width between the second deciduous molars were nearly stable or slightly increased until 6 years of age. After that, all of the deciduous tooth widths gradually increased, especially in the width between the deciduous canine at the emergence of the permanent incisors. The width between the canines decreased until 13 years of age in the maxilla and until 15 years of age in the mandibula. After that, the width between the canines were nearly stable. Until 1 year after emergence, the width between the canines decreased, in particular during the transition to the canines, based on dental age observation. The maxillary first premolar width decreased until 6 months after emergence, based on dental age observation. Thereafter, the width between the maxillary first premolars showed no clear change. The width between the mandibular first premolars, the width between the maxillary second premolars, and the width between the mandibular second premolars increased until about 2-3 years after emergence, but they showed no clear changes thereafter. The width between the maxillary first molars gradually increased until 15 years of age; there was no clear change thereafter. The width between the mandibular first molars was nearly stable throughout the observation period. The width between the maxillary second molars decreased until 2 years after emergence; no clear change was observed thereafter. The width between the mandibular second molars was unstable until after about 2-3 years after emergence and then became nearly stable.

Abstract
The Pk-1slc gene encodes a mutant red blood cell (RBC) type pyruvate kinase (PK), and adult CBA-Pk-1slc/Pk-1slc mice show a severe nonspherocytic hemolytic anemia. However, the number of RBCs and the proportion of reticulocytes were comparable between neonatal CBA-Pk-1slc/Pk-1slc mice and control -+/+ mice. Since the age-dependent increase of RBCs was much greater in CBA-+/+ mice than in CBA-Pk-1slc/Pk-1slc mice, significant anemia was observed in the latter mice on day 14 after birth. The increase of RBCs in CBA-+/+ mice was due to the prolongation of their survival time. The half life of RBCs increased in CBA-+/+ mice with ages, but it decreased in CBA-Pk-1slc/Pk-1slc mice. The relatively longer half life of RBCs in neonatal CBA-Pk-1slc/Pk-1slc mice appeared to be due to the delayed switching from M2-type PK that are expressed by undifferentiated erythroid precursor cells to RBC-type PK that are expressed by mature RBCs.
