Abstract
PURPOSE To assess the additive effect of diquafosol tetrasodium on sodium hyaluronate monotherapy in patients with dry eye syndrome. METHODS This study evaluated 64 eyes of 32 patients (age: 62.6±12.8 years (mean±SD)) in whom treatment with 0.1% sodium hyaluronate was insufficiently responsive. The eyes were randomly assigned to one of the two regimens in each patient: topical administration of sodium hyaluronate and diquafosol tetrasodium in one eye, and that of sodium hyaluronate in the other. Before treatment, and 2 and 4 weeks after treatment, we determined tear volume, tear film break-up time (BUT), fluorescein and rose bengal vital staining scores, subjective symptoms, and adverse events. RESULTS We found a significant improvement in BUT (P=0.049, Dunnett test), fluorescein and rose bengal staining scores (P=0.02), and in subjective symptoms (P=0.004 for dry eye sensation, P=0.02 for pain, and P=0.02 for foreign body sensation) 4 weeks after treatment in the diquafosol eyes. On the other hand, we found no significant change in these parameters after treatment in the control eyes. CONCLUSIONS In dry eyes, where sodium hyaluronate monotherapy was insufficient, diquafosol tetrasodium was effective in improving objective and subjective symptoms, suggesting its viability as an option for the additive treatment of such eyes.

Abstract
Photodetachment of the positronium negative ion, a bound state of one positron and two electrons, has been observed. Development of a method to produce the ions efficiently using a Na coated tungsten surface has enabled the first observation of the photodetachment. The obtained lower limit of the photodetachment cross section for the wavelength of 1064 nm is consistent with the theoretical calculations reported so far. The experimental field developed in the present work gives new opportunities to explore the quantum mechanical three-body problem and to develop energy-tunable positronium beams.

Abstract
AIM To assess astigmatism induced after phakic intraocular lens (Visian ICL, STAAR Surgical) implantation. METHODS Seventy-three eyes of 47 patients undergoing ICL implantation through a horizontal 3.0 mm clear corneal incision were retrospectively examined. The amount of corneal astigmatism before and 3 months after surgery using an automated keratometer (ARK-700A, Nidek) and corneal topography (ATRAS995, Carl Zeiss Meditec) were quantitatively investigated. The surgically induced astigmatism was assessed by vector analysis using the Holladay-Cravy-Koch formula. RESULTS The corneal astigmatism was significantly increased from 1.10 (0.51) dioptres (D) to 1.44 (0.57) D using the keratometer (Wilcoxon signed-rank test, p<0.001). It was also significantly increased from 1.16 (0.53) D to 1.45 (0.57) D using corneal topography (p<0.001). On the other hand, the manifest astigmatism was significantly decreased from 0.93 (0.60) D to 0.72 (0.58) D (p<0.001). The surgically induced astigmatism was 0.45 (0.26) D at an axis of 93.3 degrees using the keratometer and 0.49 (0.26) D at an axis of 98.0 degrees using corneal topography. CONCLUSIONS ICL implantation induces corneal astigmatism through a with-the-rule astigmatic shift of approximately 0.5 D, which was small but not negligible for candidates for refractive surgery.

Abstract
Benzodiazepines (BZs) suppress ventilation possibly by augmenting the GABA(A) receptor activity in the respiratory control system, but precise sites of action are not well understood. The goals of this study were: (1) to identify GABA(A) receptor subunits in the carotid body (CB) and petrosal ganglion (PG); (2) to test if BZs exert their effects through the GABA(A) receptor in the CB chemosensory unit. Tissues were taken from euthanized adult cats. RNA was extracted from the brain, and cDNA sequences of several GABA(A) receptor subunits were determined. Subsequent RT-PCR analysis demonstrated the gene expression of alpha2, alpha3, beta3, and gamma2 subunits in the CB and the PG. Immunoreactivity for GABA and for GABA(A) receptor beta3 and gamma2 subunits was detected in chemosensory glomus cells (GCs) in the CB and neurons in the PG. The functional aspects of the GABA-GABA(A) receptor system in the CB was studied by measuring CB neural output using in vitro perfusion setup. Two BZs, midazolam and diazepam, decreased the CB neural response to hypoxia. With continuous application of bicuculline, a GABA(A) receptor antagonist, the effects of BZs were abolished. In conclusion, the GABA-GABA(A) receptor system is functioning in the CB chemosensory system. BZs inhibit CB neural response to hypoxia by enhancing GABA(A) receptor activity.

Abstract
BACKGROUND An increased understanding of the ocular surface at cellular level in the conjunctiva and the cornea may help explain the pathogenesis and the subsequent clinical appearance of atopic ocular allergies, which may be potentially blinding. PURPOSE To investigate the MUC16 and MUC5AC alterations, tear function and the ocular surface disorder in patients with atopic keratoconjunctivitis (AKC). METHODS Thirty-six eyes of 18 AKC patients as well as 28 eyes of 14 age- and sex-matched normal subjects were studied. The subjects underwent corneal sensitivity measurements, Schirmer test, tear film break-up time (BUT), fluorescein and Rose-Bengal staining of the ocular surface, conjunctival impression cytology and brush cytology. Impression cytology samples underwent periodic acid schiff and immunohistochemical staining with MUC16 and MUC5AC antibodies. Brush cytology specimens underwent evaluation for inflammatory cell numbers and quantitative real-time polymerase chain reaction (PCR) for MUC16 and MUC5AC mRNA expression. RESULTS The mean corneal sensitivity and BUT values were significantly lower in patients with AKC, compared with controls (P < 0.001). Brush cytology specimens from AKC patients revealed significantly higher numbers of inflammatory cells (P < 0.001). Specimens from patient eyes showed positive staining for MUC5AC and MUC16. MUC16 mRNA expression was significantly upregulated with significant downregulation of MUC5AC mRNA expression in eyes with AKC compared with the eyes of control subjects. CONCLUSION Ocular surface inflammation, decline in corneal sensitivity, tear film instability, changes in conjunctival epithelial MUC5AC and MUC16 mRNA expressions were thought to be important in the pathogenesis of atopic ocular surface disease.

Abstract
BACKGROUND The pathogenesis of the ocular surface disease in atopic keratoconjunctivitis (AKC) and vernal keratoconjunctivitis (VKC) has not been fully understood. We tried to clarify the differences in the ocular surface status in patients with AKC, VKC, and healthy control subjects. METHODS Twenty-four eyes of 12 AKC patients, 12 eyes of six VKC patients, and 20 eyes of 10 normal control subjects were studied. The subjects underwent corneal sensitivity measurements, Schirmer test, tear film break-up time (BUT), vital staining of the ocular surface, conjunctival impression and brush cytology. Impression cytology samples underwent periodic acid Schiff staining for goblet cell density, squamous metaplasia grading, and immunohistochemical staining for MUC1, 2, 4, and 5AC. Brush cytology specimens underwent staining for inflammatory cell counting and Real Time PCR for MUC1, 2, 4, and 5AC mRNA expression. RESULTS The mean BUT, corneal sensitivity, and conjunctival goblet cell density values in AKC patients were significantly lower compared with VKC patients and control subjects. The squamous metaplasia grades in eyes with AKC were significantly higher compared to eyes with VKC and controls. The inflammatory cell response in brush cytology specimens was different between patients with AKC and VKC. Eyes with AKC showed significantly higher MUC1, 2 and 4 and lower MUC5AC mRNA expression compared to eyes with VKC. CONCLUSIONS Differences of the infiltrates, higher level of tear instability, lower corneal sensitivity, up-regulation of MUC1, 2, and 4, and down regulation of MUC5AC were important differential features of the ocular surface disease in AKC compared with VKC.

Abstract
BACKGROUND AND OBJECTIVE Molecular gene markers, which can distinguish human bone marrow mesenchymal stem cells from human fibroblasts, have recently been reported. Messenger RNA levels of tissue factor pathway inhibitor-2, major histocompatibility complex-DR-alpha, major histocompatibility complex-DR-beta, and neuroserpin are higher in human bone marrow mesenchymal stem cells than in human fibroblasts. However, human bone marrow mesenchymal stem cells express less apolipoprotein D mRNA than human fibroblasts. Periodontal ligament cells are a heterogeneous cell population including fibroblasts, mesenchymal stem cells, and progenitor cells of osteoblasts or cementoblasts. The use of molecular markers that distinguish human bone marrow mesenchymal stem cells from human fibroblasts may provide insight into the characteristics of human periodontal ligament cells. In this study, we compared the molecular markers of human periodontal ligament cells with those of human bone marrow mesenchymal stem cells and human gingival fibroblasts. MATERIAL AND METHODS The mRNA expression of the molecular gene markers was analyzed using real-time polymerase chain reaction. Statistical differences were determined with the two-sided Mann-Whitney U-test. RESULTS Messenger RNA levels of major histocompatibility complex-DR-alpha and major histocompatibility complex-DR-beta were lower and higher, respectively, in human periodontal ligament cells than in human bone marrow mesenchymal stem cells or human gingival fibroblasts. Human periodontal ligament cells showed the lowest apolipoprotein D mRNA levels among the three types of cells. CONCLUSION Human periodontal ligament cells may be distinguished from human bone marrow mesenchymal stem cells and human gingival fibroblasts by the genes for apolipoprotein D, major histocompatibility complex-DR-alpha, and major histocompatibility complex-DR-beta.

Brush cytology specimens underwent evaluation for inflammatory cell numbers and quantitative real-time-PCR for MUC 1, 2 and 4 mRNA expression. Patient eyes with fluorescein and Rose Bengal scores greater than four points were regarded to have significant epithelial disease in this study. RESULTS The mean corneal sensitivity and BUT values were significantly lower in atopic patients with significant epithelial disease, compared with patients with insignificant epithelial disease and controls (P < 0.01). Brush cytology specimens from patients with significant epithelial disease revealed significantly higher numbers of inflammatory cells (P < 0.01). Specimens from patient eyes showed positive staining for MUC 1, 2 and 4. MUC 1, 2 and 4 mRNA expressions were significantly higher in eyes with significant epithelial disease compared with eyes with insignificant epithelial disease and eyes of control subjects.

Abstract
Rothmann-Makai syndrome (lipogranulomatosis subcutanea) is a rare variant of Weber-Christian disease, but lacks visceral involvements and systemic manifestations. We herein report the case of a 56-year-old Chinese woman with this disorder who complained of subcutaneous tender nodules over her extremities, trunk, and face of 2 years' duration. She was firstly treated with 300 mg of oral roxythromycin for 8 weeks and subsequently treated with 400 mg of oral clarithromycin for the next 8 weeks. However, no significant effect was observed. She was then administered 200 mg of oral minocycline hydrochloride. After 1 week, her skin symptoms rapidly improved and no relapse has been observed in a follow-up period of 3 months. Considering that tetracycline antibiotics, but not macrolide antibiotics, inhibit the activity of pancreatic lipase in vitro, the efficiency of tetracycline antibiotics may be a clue to clarifying the pathogenesis of this disorder.

Abstract
MCG (Magnetocardiography) measurement by a SQUID gradiometer was attempted with only active magnetic shielding (active shielding). A three-axis-canceling-coil active shielding system, where three 16-10-16 turns-coil sets were put in the orthogonal directions, produces a homogeneous magnetic field in a considerable volume surrounding the center. Fluxgate sensors were used as the reference sensors of the system. The system can reduce environmental magnetic noise at low frequencies of less than a few Hz, at 50 Hz and at 150 Hz. Reducing such disturbances stabilizes biomagnetic measurement conditions for SQUIDs in the absence of magnetically shielded rooms (MSR). After filtering and averaging the measured MCG data by a first-order SQUID gradiometer with only the active shielding during the daytime, the QRS complex and T wave was clearly presented.

Abstract
Generalized pustular psoriasis (GPP) is a rare but notoriously recalcitrant cutaneous diseases. Therefore, there have been few reports of more than ten patients with GPP who were treated at the same institution. The severity of this disease and its response to each therapeutic modality vary among patients. In some GPP is life-threatening, but in others it may show a benign, chronic course for a long period of time. Before starting treatment, a knowledge of the therapeutic efficacy and side effects of each drug used in the treatment of GPP is necessary. In our multicenter study, we compared the effectiveness of and adverse reactions to several systemically administered drugs. Following the development of a unique classification of the disease severity based on scoring the clinical symptoms and the laboratory findings, we propose here therapeutic guidelines for the treatment of GPP.

Abstract
Serum samples from 54 monkeys were collected from healthy individuals in a monkey farm in Luzon island, Philippines, in 1999, and examined by IgM-capture ELISA and indirect IgG ELISA for the presence of dengue (DEN), Japanese encephalitis (JE) and chikungunya (CHIK) viruses. The positive rates for IgM ELISA were 3.7, 35.2 and 14.8% against DEN, JE and CHIK, respectively. Higher positive rates were obtained when indirect IgG ELISA was used: 100% against flaviviruses (JE or DEN) and 59.3% against CHIK virus. The results indicate a high prevalence of flavivirus infections such as JE and DEN, and a lesser prevalence of CHIK virus infections, among monkeys in the Philippines. These findings suggest possible sylvatic transmission cycles of these viruses.

Abstract
We report herein the case of a 33-year-old woman who presented with palpable abdominal swelling found to be caused by a huge lymphangioma of the pancreas. An abdominal computed tomographic (CT) scan showed a large multilocular cystic mass with water-dense contents, which was derived from the pancreatic head. A pancreaticoduodenectomy (PD) was performed because the tumor had invaded the duodenum. The resected tumor, which was 23 x 12 x 23 cm in size with 21 of serous fluid, was pathologically diagnosed as a cystic lymphangioma. The endothelial cells lining the internal surface of the cystic spaces were immunohistochemically positive for factor VIII-R antigen and CD31. Our review of the literature revealed 45 reports of lymphangioma of the pancreas, including this one, but to the best of our knowledge this is only the fifth case that required a PD. Nevertheless, we recommend that a complete resection be performed to reduce the risk of recurrence.
