Abstract
Metaplastic carcinoma is a rare histological malignancy, often triple-negative, and has a poor prognosis. Here, we report a case of breast cancer in which the primary lesion degenerated into squamous cell carcinoma(triple negative)after drug treatment for invasive ductal carcinoma(Luminal type). The patient was a 41-year-old woman who was diagnosed with Stage Ⅳ left breast cancer T2N2bM1(HEP)(ER 90%, PR 70%, HER2 2+, FISH-)at another hospital and participated in the PATHWAY study(tamoxifen plus goserelin plus palbociclib/placebo). Since the primary lesion and liver metastasis increased in size, the study was discontinued after 8 weeks. She was treated at our hospital thereafter, with capecitabine plus cyclophosphamide, palbociclib plus fulvestrant plus leuprorelin, paclitaxel plus bevacizumab, eribulin, EC therapy, and docetaxel. However, both the primary lesion and liver metastasis increased. In particular, the increase in primary lesion size was remarkable, and the QOL significantly reduced due to bleeding and exudation. Biopsy performed during docetaxel treatment revealed metaplastic/squamous cell carcinoma(ER-, PR-, HER2 0, Ki-67 90-100%)histopathological findings. BRCA and microsatellite instability tests were negative, and PDL1 expression was less than 1%. Although Mohs ointment was used, tumor bleeding, exudate, and stink were poorly controlled, and the patient experienced painful symptoms due to the weight of the tumor. Therefore, left mastectomy plus pectoralis major muscle resection was performed. The patient died one month after the operation.

Abstract
A 54‐year‐old man had previously undergone curative sigmoidectomy for poorly differentiated adenocarcinoma with a signet‐ring cell component of the sigmoid colon, which was characterized morphologically by stenosis and inelasticity of the colon (linitis plastica). Six weeks after surgery, the patient developed stenosis of the right ureter. Disseminated sigmoid cancer was suspected, and chemotherapy was started. Nine months after initiation of chemotherapy, obstructive jaundice was observed which was due to stenosis of the distal bile duct (BD). Although computed tomography showed no evident metastatic lesion that could cause the stenosis, swelling of the entire pancreas was evident compared to that of 11 months earlier. Endoscopic ultrasound (EUS) also did not detect any focal masses in the head of the pancreas, although there was a diffuse hypoechoic change in the entire pancreas. Histopathology of the stenotic BD and biopsy specimen from the head of the pancreas showed no malignant cells. Two months after the initial endoscopic bile duct drainage, the patient was admitted again for epigastric pain. A second EUS fine needle aspiration (EUS‐FNA) of the head of the pancreas was performed and showed poorly differentiated carcinoma with some signet‐ring cells. This finding provided histological confirmation of a disseminated pancreatic lesion of the previously resected linitis plastica of the sigmoid colon. This is a rare case of disseminated pancreatic lesion from primary linitis plastica of the colon diagnosed by EUS‐FNA.

Abstract
Melanogenesis is the biological and biochemical process of melanin and melanosome biosynthesis. Melanin is formed by enzymic reactions of tyrosinase family proteins that convert tyrosine to form brown-black eumelanin and yellow-red pheomelanin within melanosomal compartments in melanocytes, following the cascades of events interacting with a series of autocrine and paracrine signals. Fully melanized melanosomes are delivered to keratinocytes of the skin and hair. The symbiotic relation of a melanocyte and an associated pool of keratinocytes is called epidermal melanin unit (EMU). Microphthalmia-associated transcription factor (MITF) plays a vital role in melanocyte development and differentiation. MITF regulates expression of numerous pigmentation genes for promoting melanocyte differentiation, as well as fundamental genes for maintaining cell homeostasis. Diseases involving alterations of EMU show various forms of pigmentation phenotypes. This review introduces four major topics of melanogenesis cascade that include (1) melanocyte development and differentiation, (2) melanogenesis and intracellular trafficking for melanosome biosynthesis, (3) melanin pigmentation and pigment-type switching, and (4) development of a novel therapeutic approach for malignant melanoma by elucidation of melanogenesis cascade.

Abstract
A 13-yr-old boy who complained of persistent nausea, vomiting and weight loss had
hypercalcemia and an elevated intact PTH level. Computed tomography confirmed two tumors
in the thyroid gland. The tumors were surgically removed and pathologically confirmed as
parathyroid adenoma. Because his maternal aunt and grandmother both had histories of
parathyroid tumors, genetic investigation was undertaken for him, and a germline
frameshift mutation of the CDC73 gene was identified.
CDC73 gene analysis should be done on individuals who are at risk of
familial hyperparathyroidism, including those who are asymptomatic, and they should be
followed for potential primary hyperparathyroidism and associated disorders including
resultant parathyroid carcinoma.

Abstract
Biliary tract cancers have an extremely poor outcome, and specific diagnostic markers and effective treatments are needed urgently. In this study, we assessed the capacity of panel of immunohistochemical markers including claudin-18, maspin, and p53 to distinguish biliary tract carcinoma and biliary intraepithelial neoplasia (BilIN) from non-neoplastic epithelium. We performed a retrospective study of 66 biliary tract cancer specimens and 63 specimens with non-neoplastic lesions. Of the surgical specimens, 96.7 % with adenocarcinoma/BilIN were detected as neoplastic, and all 63 specimens histologically diagnosed as non-neoplastic lesion were detected as non-neoplastic with high sensitivity (91.1 %) and specificity (100 %). Of presurgical endobiliary forceps biopsy specimens, all with adenocarcinoma/BilIN and only 1 of the 19 with a non-neoplastic lesion were distinguished as neoplastic with high sensitivity (100 %) and specificity (94.7 %). Moreover, this panel provided good separation of neoplasm from malignancy-undetermined atypical epithelium (18/21, 85.7 %). This panel achieves a more reliable distinction of biliary tract cancers and BilINs from non-neoplastic epithelia in both surgical and biopsy specimens than immunohistochemical analysis with single antibodies and is useful in supporting a diagnosis of adenocarcinoma and BilIN.

Abstract
Neuroblastoma is a malignant tumor predominantly occurring in children and usually arising from the adrenal gland or sympathetic ganglia. We describe a neuroblastoma in a 1-month-old boy arising from his left orbital cavity. This tumor was refractory to chemotherapy or radiotherapy, requiring enucleation of the left eye for complete removal of the intraorbital tumor. Thereafter, he received high-dose chemotherapy followed by autologous peripheral blood stem cell transplantation, and has been in complete remission for 3 years. Unlike neuroblastomas arising from the adrenal gland or sympathetic ganglia, primary orbital neuroblastoma may be refractory even in early infancy.

Abstract
Mesenchymal chondrosarcoma (MC) is an extremely rare subtype of chondrosarcoma. A tumor specific fusion gene, HEY1-NCOA2 fusion, was recently identified in this tumor. The finding raises the possibility that the diagnosis of MC can be improved by examining the fusion gene. In the present study, we aimed to evaluate the efficacy of fluorescence in situ hybridization (FISH) in detecting HEY1-NCOA2 fusion for the diagnosis of MC. Specimens from 10 patients diagnosed with MC were used for the study. Dual-color FISH was performed using two different probes that specifically hybridize to HEY1 and NCOA2, respectively. Fusion signals were identified in all but two specimens, in which no signal was detected, presumably because of inadequate sample preparation. In accordance with results of a previous study, FISH analysis was highly sensitive in detecting HEY1-NCOA2 fusion in adequately prepared MC samples. The current study adds further support for the use of HEY1-NCOA2 fusion as a valid diagnostic marker for MC.

Abstract
BACKGROUND AND AIM Endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) is an established diagnostic method for patients with suspected pancreatic ductal carcinoma. Rapid on-site evaluation (ROSE) has been reported to improve the accuracy. However, an on-site cytopathologist is not routinely available in many institutions. One of the solutions may be ROSE by endosonographer. The aim was to examine whether diagnostic accuracy increases through ROSE by endosonographer using our cytological criteria. METHODS Patients who underwent EUS-FNA of solid pancreatic masses from January 2006 to August 2009 (n = 53, period 1) and September 2009 to April 2011 (n = 85, period 2) were retrospectively identified. Before initiating ROSE at the start of period 2, two endosonographers underwent training for cytological interpretation, which was focused on four cytological features of pancreatic ductal carcinoma: anisonucleosis, nuclear membrane irregularity, overlapping, and enlargement. During EUS-FNA in period 2, endosonographers classified the Diff-Quik smears under three atypical grades and evaluated the adequacy. All diagnoses were made by one pathologist without knowledge of clinical information. RESULTS The rate of "inconclusive" diagnoses, interpreted as "suspicious," "atypical," and "inadequate for diagnosis" was reduced from 26.4% in period 1 to 8.2% in period 2 (P = 0.004). Moreover, diagnostic accuracy was increased from 69.2% in period 1 to 91.8% in period 2 (P < 0.001). CONCLUSIONS This cytological grading system used in ROSE by endosonographers is invaluable for the diagnosis of pancreatic solid masses.

Abstract
With the aim of standardizing Ki-67 immunohistochemistry, we assessed interobserver and interlaboratory variability of the Ki-67 labeling index and Ki-67 score among eight general pathologists for 24 gastrointestinal stromal tumors (GISTs) and 12 leiomyosarcomas, which were predominantly of the gastrointestinal (GI) tract, mesentery and retroperitoneum, based on a review of a tissue microarrays subjected to immunohistochemistry with antibodies for Ki-67. For Ki-67 immunostaining of mesenchymal tumors of the GI tract, including GISTs, differences were seen in the scores given by regional hospitals. Conversely, for two categories of the Ki-67 labeling index, namely <10% and ≥10%, concordance of the Ki-67 score between microscopic observation and image analysis, and between the observers, was good, but it was not good for the other four categories of the index for <5%, 5-9%, 10-29%, and ≥30%. The concordance of the Ki-67 scores between the observers in two categories was higher using the Ki-67 pre-stained tissue microarrays (TMAs) within each participating institute than that using the Ki-67 stained TMAs between the participating institutes. The reproducibility of a 10% cut-off value for the Ki-67 labeling index to predict the prognosis of GISTs was relatively high, but there is an urgent need to standardize the staining technique.

Abstract
Previously, we showed that the expression of potassium channel tetramerization domain-containing 12 (KCTD12), which was discovered by a proteomics approach, is associated with high-risk behavior of gastrointestinal stromal tumors (GISTs). Here, we examined the distribution and expression of this protein by immunostaining with a commercially available polyclonal KCTD12 antibody in GISTs (n = 64) and other types of malignancy (n = 168) to clarify its diagnostic and clinical significance. Diffuse KCTD12 immunoreactivity was found in most GISTs (52 cases; 81%). KCTD12 expression was observed primarily in vascular endothelial cells, Purkinje cells of the cerebellum, and some neurons scattered throughout the cerebral cortex. KCTD12 was absent from not only the interstitial cells of Cajal but also interstitial cells of Cajal hyperplasia that was encountered incidentally in colon diverticulitis. KCTD12 immunostaining was also seen in malignant peripheral nerve sheath tumors (2/10 cases; 20%), synovial sarcomas (2/10; 20%), solitary fibrous tumor (1/8; 13%), angiosarcoma (1/7; 14%), and colon adenocarcinoma (1/24; 4%). In survival analyses, the 5-year recurrence-free survival rate of patients without KCTD12 expression was only 16.7% compared with 95.6% in those with KCTD12 expression (P < .0001). Ki-67 and KCTD12 were significant predictors of recurrence-free survival, and KCTD12 expression provided additional information about recurrence-free survival after accounting for Ki-67 status. Overall, KCTD12 expression was specific for GISTs from neoplastic and nonneoplastic adult tissues other than brain and served as a predictor of GIST recurrence. These findings suggest that KCTD12 is a useful and reliable biomarker for both the diagnosis and prognosis of GIST.

Abstract
Interferon (IFN) is believed to be one of the most effective anti-melanoma agents. Specifically, IFN-beta has the ability to induce apoptosis of melanoma cells. Induction of tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) has also been suggested to have a critical role in IFN-beta-induced apoptosis. To characterize the signaling pathway involved in IFN-beta-induced apoptosis, we analyzed the biological effects of IFN-beta on the cell death and caspase activation of melanoma cells. IFN-sensitive cell lines, MM418, SK-mel-23, and SK-mel-118, showed increased apoptotic populations correlated with the activation of caspase-2 and caspase-3 by IFN-beta. IFN-beta-induced apoptosis was significantly suppressed by inhibitors for caspase-2 or caspase-3, but not by inhibitors for caspase-8 or caspase-9 in these cell lines. TRAIL expression was observed in IFN-beta-treated cells of SK-mel-23 and SK-mel-118, but not in those cells of MM418, which showed massive IFN-beta-induced apoptosis and resistance to exogenous TRAIL-mediated apoptosis. G361 was resistant to IFN-beta-induced apoptosis but sensitive to exogenous TRAIL-mediated apoptosis. Furthermore, IFN-beta pretreatment significantly increased the sensitivity against exogenous TRAIL-mediated apoptosis and activation of caspase-2 in G361. These results suggested that caspase-2 activation is commonly associated with induction of IFN-beta-induced apoptosis in IFN-beta-sensitive melanoma cells.

Abstract
Psoralen plus ultraviolet A (PUVA) photochemotherapy is widely used for the therapy of mycosis fungoides (MF). Clinical progression of MF is often associated with an increase in the size of tumour cells known as transformation. We report two patients with CD30+ large cell transformation that appeared after low-dose PUVA therapy for MF. Clinical data, histopathology, immunohistopathology and T-cell receptor gene rearrangement were studied. Nodules consisted of atypical large cells that expressed CD30. Monoclonal rearrangement of T-cell receptors was observed in one case. Low-dose PUVA therapy may be associated with CD30+ large cell transformation in patients with MF.

Abstract
Several mutations of the tyrosine kinase domain of insulin receptor (IR) have been clinically reported to lead insulin resistance and insulin hypersecretion in humans. However, it has not been completely clarified how insulin resistance and pancreatic beta-cell function affect each other under the expression of mutant IR. We investigated the response of pancreatic beta-cells in mice carrying a mutation (P1195L) in the tyrosine kinase domain of IR beta-subunit. Homozygous (Ir(P1195L/P1195L)) mice showed severe ketoacidosis and died within 2 days after birth, and heterozygous (Ir(P1195L/wt)) mice showed normal levels of plasma glucose, but high levels of plasma insulin in the fasted state and after glucose loading, and a reduced response of plasma glucose lowering effect to exogenously administered insulin compared with wild type (Ir(wt/wt)) mice. There were no differences in the insulin receptor substrate (IRS)-2 expression and its phosphorylation levels in the liver between Ir(P1195L/wt) and Ir(wt/wt) mice, both before and after insulin injection. This result may indicate that IRS-2 signaling is not changed in Ir(P1195L/wt) mice. The beta-cell mass increased due to the increased numbers of beta-cells in Ir(P1195L/wt) mice. More proliferative beta-cells were observed in Ir(P1195L/wt) mice, but the number of apoptotic beta-cells was almost the same as that in Ir(wt/wt) mice, even after streptozotocin treatment. These data suggest that, in Ir(P1195L/wt) mice, normal levels of plasma glucose were maintained due to high levels of plasma insulin resulting from increased numbers of beta-cells, which in turn was due to increased beta-cell proliferation rather than decreased beta-cell apoptosis.

Abstract
BACKGROUND In obtain images of skin tumors non-invasively with real-time, confocal laser scanning microscope (CLSM) is introduced. OBJECTIVE Reconstructed images of given horizontal sections were converted into three-dimensions using the data set of a large number of tomograms in the horizontal directions. METHODS To develop the multiplaner reconstruction images of skin tumors in vertical directions and three-dimensionally reconstructed images of tumors will be obtained from the continuously collected horizontal image data sets. RESULTS Three-dimensional analyses of the skin tumors from reconstructed images of the CLSM scanning have provided the information as to their physiological characteristics as well as the extent of deep invasion in real-time with non-invasive manner. High performance three-dimensional conversion software was effective in displaying three-dimensional construction of skin tumors. CONCLUSION The CLSM scanning images followed by three-dimensional reconstruction using them can provide the real-time and non-invasive diagnoses of skin tumors and analyze the radial growth phase of tumors and the three-dimensional growth characteristics.

Abstract
Idiopathic acquired generalized anhidrosis is a very rare disease of unknown pathogenesis. We report a 25-year-old man with acquired generalized anhidrosis due to occlusion of the coiled ducts. He did not have sweat secretion over the entire surface of the body, including the palms and soles. Sweat-inducing stimuli provoked tingling pain on the skin. Pilocarpine iontophoresis on the forearm did not induce sweat secretion. Neurological examination did not reveal any abnormality in the central or peripheral nervous system. Skin biopsy showed that the coiled ducts were occluded by an amorphous eosinophilic substance. This amorphous eosinophilic substance was positive with periodic acid-Schiff (PAS) staining and was resistant to digestion by diastase. Electron microscopy demonstrated that the coiled ducts were completely occluded by an amorphous substance. The substance occluding the coiled ducts contained fibrous structures. These findings suggested that the acquired generalized anhidrosis in this patient was caused by occlusion of the coiled ducts by a PAS-positive substance probably derived from dark cell granules.

Abstract
OBJECTIVE effects of Fosfomycin (FOM) nebulizer therapy were studied in patients with chronic sinusitis. METHODS about 28 patients with chronic sinusitis were administered 2 ml of FOM sodium (3% w/v) by nebulizer three times per week for 4 weeks. Levels of IL-1 beta, IL-6, IL-8, and TNF-alpha in nasal lavage were also measured before and at the end of treatment. RESULTS the overall efficacy of this treatment on the basis of both subjective and objective symptoms, was 'excellent' for 28.6%, 'good' for 10.7%, 'fair' for 39.4%, and yield 'no change' for 21.4% of the patients. Both IL-1 beta and IL-6 concentrations were significantly decreased after treatment. Although the IL-8 level did not significantly decrease, it seems to be related to the overall efficacy. TNF-alpha was not detected in all of the samples. CONCLUSION FOM nebulization therapy is highly effective in treatment for chronic sinusitis, and efficacy may be due to an immunomodulatory mechanism, as well as its bactericidal effect.

Abstract
Historically, many new anticancer agents were first detected in a prescreen; usually consisting of a molecular/biochemical target or a cellular cytotoxicity assay. The agent then progressed to in vivo evaluation against transplanted human or mouse tumors. If the investigator had a large drug supply and ample resources, multiple tests were possible, with variations in tumor models, tumor and drug routes, dose-decrements, dose-schedules, number of groups, etc. However, in most large programs involving several hundred in vivo tests yearly, resource limitations and drug supply limitations have usually dictated a single trial. Under such restrictive conditions, we have implemented a flexible in vivo testing protocol. With this strategy, the tumor model is dictated by in vitro cellular sensitivity; drug route by water solubility (with water soluble agents injected intravenously); dosage decrement by drug supply, dose-schedule by toxicities encountered, etc. In this flexible design, many treatment parameters can be changed during the course of treatment (e.g., dose and schedule). The discovery of two active agents are presented (Cryptophycin-1, and Thioxanthone BCN 183577). Both were discovered by the intravenous route of administration. Both would have been missed if they were tested intraperitoneally, the usual drug route used in discovery protocols. It is also likely that they would have been missed with an easy to execute fixed protocol design, even if injected i.v.

Dendroamide A (1), one of three new bistratamide-type cyclic hexapeptides from the terrestrial blue-green alga (cyanobacterium) Stigonema dendroideum Fremy, exhibits multidrug-resistance reversing activity. The gross structures of the three compounds, dendroamides A-C, were determined by NMR and mass spectral analyses. Their absolute stereochemistries were determined by Marfey and chiral GC/MS analyses of derivatives formed from acid hydrolysis of the intact and ozonized peptides.

Abstract
Cryptophycin-8 was prepared by the conversion of the epoxide group on cryptophycin-1 to a chlorohydrin. In the studies reported here, cryptophycin-8 was evaluated for preclinical activity against subcutaneous tumors of both mouse and human origin. At the highest non-toxic single course treatment, the following results were obtained (Table A). Cryptophycin-8 was less potent than cryptophycin-1 by approximately 4-fold; however, it was both more water soluble and had greater therapeutic efficacy, as demonstrated by % T/C, tumor cell log kill values, range of dose effectiveness and host cures.

Abstract
Tooth preparation dust, an indispensable part of dental treatment, contains bacteria and viruses. In order to examine environmental pollution in the dental clinic during tooth preparation, we monitored microorganism spread by counting colony forming units (CFU) with the "Andersen Microbe Sampler." This test was conducted in a "Clean Booth." Mitis-salivarius medium was used to count the oral-streptococcus species. The ability of the "Extra-Oral Vacuum Aspirator (EOVA)" to effectively eliminate contamination was also tested, and the EOVA was found to reduce the spread of oral-streptococci, significantly. The EOVA was therefore viewed as an effective method for reducing air pollution in the dental clinic, and should be used when treating patients with certain infectious diseases.

Abstract
The role of normal pharyngeal flora in the defense mechanism against infections in the upper respiratory tract was studied in 50 children with otitis media with effusion (O.M.E.). In the bacteriological study of the nasopharynx, the incidence of H. influenzae, S. pneumoniae, S. aureus, M. catarrhalis and group A Streptococcus was about 46%, 24%, 20%, 12% and 8%, respectively. The incidence of these species in the cases with O.M.E. was higher than that in the cases with chronic tonsilitis or control cases. In 41 O.M.E. cases with alpha-streptococci (82%), the incidence of alpha-streptococci with inhibitory activity against 5 pathogens (H. influenzae, S. pneumoniae, S. aureus, M. catarrhalis, group A Streptococcus) was examined. The detection rate of alpha-streptococcal strains with inhibitory activity against 5 pathogens derived from the nasopharynx in the cases with O.M.E. was significantly lower than that of the strain in the chronic tonsilitis cases and the control cases. Moreover, the detection rate of inhibitory alpha-streptococci from the nasopharynx was lower than that of from the tonsil. These findings suggest that the decline of inhibitory activity against pathogens by normal flora in nasopharynx is one of the factors causing O.M.E.

Abstract
We investigated the distribution of oral alpha-streptococci with inhibitory activity against pathogens, which compose an oral defense mechanism. Detection rate of alpha-streptococci with inhibitory activity against S. pyogenes and S. aureus derived from the tonsil was higher than in other portions, the tongue, cheek, gingiva, or saliva. It has suggested that tonsillar bacterial flora are mainly a defense mechanism. The oral flora in healthy smokers was compared with healthy non-smokers to investigate the influence of tobacco on oral bacterial flora. The results showed that the detection rate of S. aureus in smokers was higher while that of alpha-streptococci with inhibitory activity against S. aureus was lower. However, the detection rate of alpha-streptococci with inhibitory activity against S. pyogenes in smokers was as high as in non-smokers. It is suggested that it was easy for S. aureus to adhere to the oral mucosa in smokers, and was considered to influence the strain which produces beta-lactamase for medical treatment. We investigated the influence of gargling on oral bacterial flora by comparing the amount of bacteria before and after gargling with popidine-iodine gargle and saline solution. It was shown that alpha-streptococci, a main component of normal oral flora were decreased after gargling in both smokers and non-smokers. Furthermore, it was shown that group A Streptococcus was not decreased after gargling, and it was concluded that use of gargle medicinal mouth wash in bacillus carriers should be studied further.

Abstract
The purpose of this report is to examine the effect of Macrolides (Erythromycin and Roxythromycin) on swarming ability and antistaphylococcal activity of Pseudomonas aeruginosa. The standard strain (ATCC27854) and clinically isolated P. aeruginosa were used as test strains. The influence of Macrolides on antistaphylococcal activity and swarming ability were determined by the agar plate dilution method. The antistaphylococcal activity of P. aeruginosa was not affected at the concentration of 1.56 micrograms/ml of both Erythromycin and Roxythromycin. But the antistaphylococcal activity was not observed at the concentration over 100 micrograms/ml. The swarming ability was not affected at the concentration up to 12.5 micrograms/ml. It has been proved that Macrolides reveal inhibition of virulent factors of P. aeruginosa such as protease, elastase, piocianin and so on. Furthermore our data revealed that Macrolides inhibited swarming ability of P. aeruginosa, and did not affect the antistaphylococcal activity of P. aeruginosa under 1.56 micrograms/ml concentration. Consequently, these results suggest that Macrolides have exhibited a previously unknown pharmacological effect, and may be of interest in that there may be bacterial interaction between MRSA and P. aeruginosa.

Abstract
In this open randomized study, we evaluated the efficacy of Tranilast, one of the anti-inflammatory drugs, on otitis media with effusion in children. Sixty-two patients (103 ears) were divided into two groups: Group A was given Tranilast and local treatment (nasal and tubal); Group B only received local treatment (control for Group A). The overall improvement rating assessed as "moderately improved or above" for Group A was 63.6%, Group B 47.9%. There was a significant improvement in Group A as compared to Group B (p < 0.05). In subjects who suffered from otitis media with effusion for over 2 months. Group A exhibited 50.0% of efficacy while Group B only 15.4% (p < 0.05).

Abstract
Anti staphylococcal activity by Pseudomonas aeruginosa was investigated through the use of the reversed agar plate and the filter paper stamp methods. Investigation was also conducted on the dye production of different clinical isolates of Pseudomonas aeruginosa, the relationship between drug susceptibility and anti staphylococcal activity, and the influence of erythromycin on anti staphylococcal activity. Seventy four strains of Pseudomonas aeruginosa were prepared which included 20 strains from pus, 34 strains from sputum and 20 strains from urine. These were then inoculated with methicillin resistant Staphylococcus aureus (MRSA). They were then cultured for 48 hours by using the reversed agar plate and the filter paper stamp methods. Anti staphylococcal activity was observed in 16 strains from pus (80%), 19 strains from sputum (55.9%) and 8 strains from urine (40%). The Pseudomonas aeruginosa strains which have no pigment tended to show poor anti staphylococcal activity. Drug susceptibility was tested using PIPC, AMK, IPM, CFS and OFLX. The strains which showed resistance to OFLX tended to show poor anti staphylococcal activity. Erythromycin inhibited the dye production of Pseudomonas aeruginosa but exhibited no effect on anti staphylococcal activity. Consequently, these results suggest erythromycin has exhibited a previously unknown pharmacological effect, furthermore, anti staphylococcal activity was not caused by pigmentation only.

Abstract
The alpha-streptococci, consisted of normal oral flora mainly, with inhibitory activity against pathogenic microbes in healthy individuals was investigated by group A Streptococcus (indicator strain 6-22 nonmucoid T-12). Rate of alpha-streptococci with inhibitory activity against group A Streptococcus was increased as aging, and the rate in pre-school children was higher than that in school children. These results suggested that more than 90% of the tested alpha-streptococci with strong inhibitory activities (S. salivarius) against indicator strain had inhibitory activities against group A Streptococcus (mucoid T-6), H. influenzae, S. pneumoniae, group C Streptococcus, and from 40% to 70% of the tested strains had also inhibitory activities against other pathogens. As there were many strains of alpha-streptococci with inhibitory activities against pathogens, that usually detected in the upper respiratory infection, the problem on the strains in the future will explain significance of the defense mechanism against upper respiratory infection and this can be applied clinically.

Abstract
Anti staphylococcal activity by clinical isolates of Pseudomonas aeruginosa was tested by the reversed agar plate and the filter paper stamp methods. Almost 40% of Pseudomonas aeruginosa inhibited the growth of both Methicillin resistant Staphylococcus aureus (MRSA) and Methicillin sensitive Staphylococcus aureus (MSSA). Green pigment (Pyocyanin) produced strains showed a strong inhibitory effect against MRSA and MSSA respectively. But some other pigment (Yellow, Red) strains also showed anti staphylococcal activity. These data suggest the colonization of Pseudomonas aeruginosa with anti staphylococcal activity may not be eradicated by the anti pseudomonic antibiotics.

Abstract
Since the end of 1987, we have noticed an increasing incidence of Methicillin resistant Staphylococcus aureus (MRSA) among the inpatients of Yamanashi Medical College Hospital. MRSA strains were identified in 70-80 percent of the specimens obtained from patients with Staphylococcus aureus. From 1988 we performed yearly bacteriological examinations of the nares of medical personnel at Yamanashi Medical College Hospital. We treated nasal carriers with OFLX drop lotion or Povidone-iodine applied to the nares. In 1991 we treated eight nasal carriers, who had been unsuccessfully treated with Povidone-iodine, with 0.01% Methylrosanilinium Chloride ointment which was applied to the nares once a day for two weeks. A post-bacteriological examination again revealed that MRSA vanished from the nares of six nasal carriers. The minimum inhibitory concentration (MIC) of Methylrosanilinium Chloride was determined by the agar plate dilution method. The 100% MICs of MSSA were 1.0 microgram/ml and of MRSA were 1.0 microgram/ml by Methylrosanilinium Chloride. Moreover we examined the MICs of Methylrosanilinium Chloride against MRSA under the existing 5% Albumin, and consequently the 100% MICs were 4.0 micrograms/ml. Therefore a 0.01% Methylrosanilinium Chloride has sufficient efficacy against MRSA. The reaction of the skin and nasal mucosa to Methylrosanilinium Chloride was examined by using three groups of guinea pigs. 0.1% and 0.01% Methylrosanilinium Chloride ointment and hydrophylic poloid were applied to the nares and skin once a day for two weeks. Post-observation with an opticmicroscope revealed no significant findings. Methylrosanilinium Chloride shows good anti-Staphylococcus aureus ability. Further investigation is needed to determine if Methylrosanilinium Chloride has additional clinical application.
