  • Health state of the Japanese scallop, Mizuhopecten yessoensis, cultured in the Experimental Marine Farm in Minonosok Bay (Peter the Great Bay, Sea of Japan) was investigated. The wide spectrum of histopathological changes has been identified in the internal organs and tissues of scallops: prokaryotic infection with prevalence 100%, destruction of digestive epithelium and other changes in digestive system, infiltration of organs by hemocytes and granulocytome formation. The most affected by prokaryotic infection organs are labial palps, lips, esophagus, intestine and gills. Several of the observed alterations seem to be related to prokaryotic infection.

  • 현재 종합병원에서는 21세기 최첨단 의료 IT시대에 맞지 않는 단순한 검체관리의 부주의 및 비효율적인 관리로 인해서 병리조직의 인식을 수기로 기록하여 정보의 불일치와 업무적인 미스매칭으로 인하여 의료사고가 증가하고 있다. 본 논문에서는 병리조직 검사 시스템 정보화를 위한 카세트, 슬라이드 출력기 및 정보관리 소프트웨어를 설계하였고, 카세트 프린터에 RFID를 장착하여 정보를 슬라이드 프린터와 연동하여 관리할 수 있는 시스템을 설계하여 의료사고를 방지 및 u-Hospital 분야에서 효율적으로 활용될 수 있다.

  • Background: Nasopharyngeal carcinoma (NPC) is an aggressive disease and tends to involve surrounding tissues, and biomarkers for better management are yet to be identified. Materials and Methods: One hundred and fifty tissue samples with NPC diagnosis were were investigated using pan cytokeratin (CK) and epithelial membrane protein 2 (EMP2) antibodies. Results: Immunohistochemical expression of CK was identified in 144/150 (96%) and of EMP2 in 120/150 (80%). Conclusions: There is a high loss of EMP2 in NPC, especially high grade examples. Loss of CK expression is also linked to high grade NPC types.

  • Periductal stromal sarcoma (PSS) is a type of rare malignant fibroepithelial tumor. PSS is a recently introduced diagnostic entity and there are few reports about radiological features of this tumor. Pre-operative diagnosis is difficult because it reveals similar symptoms with other benign and malignant tumors with absence of specific radiologic findings. We present a woman age 30 that underwent mammotome biopsy for a BI-RADS 4 lesion on her left breast and received histopathology diagnosis of a phyllodes tumor. Additionally, she underwent a wide excision depending on her histopathology diagnosis. Her final diagnosis was PSS. Six months later, no recurrence was detected. However, frequent follow-up is needed because PSS can develop into phyllodes tumor or entity of breast cancer.

  • This study was conducted to obtain acute information of the oral dose toxicity of DHU001, a polyherbal formula in male and female mice. In order to calculated 50% lethal dose ($LD_{50}$) and approximate lethal dose (LD), test material was once orally administered to male and female ICR mice at dose levels of 2000, 1000, 500, 250 and 0 (vehicle control) ml/kg (body weight). The mortality and changes on body weight, clinical signs, gross observation, organ weight and histopathology of principle organs were monitored 14 days after treatment with DHU001. We could not find any mortalities, DHU001 treatment-related clinical signs, changes on the body and organ weights, gross and histopathological findings. The results obtained in this study suggest that $LD_{50}$ and approximate LD in mice after single oral dose of DHU001 were considered over 2000 mg/kg in both female and male mice.

  • The management of rectal cancer is a major undertaking. There are currently multiple treatment modalities with variable degrees of complications. Radiotherapy (RT) is one of the more frequently used modalities either on its own or more frequently with chemotherapy mostly before the definitive surgery. The outcome of RT is unpredictable. RT has its serious side effects and there are no guarantees of its usefulness in all patients. This article outlines the effect of RT on the tumor, reviews the various staging systems of responses to RT and present recent evidence of which case is less responsive to such treatments to avoid unnecessary complications.

  • We evaluated the wholesomeness of fish feeds treated with high-dose radiation. This study examined the safety of fish fed treated with high-dose irradiation (5 kGy) and butylated hydroxyanisole (BHA, 200 ppm). 100 flounder (Paralichthys olivaceus) were grouped into 4 and then the fishes fed the following feeds for 28 days: (1)standard feed; (2)standard feed, treated with BHA; (3)standard feed, irradiated to 5 kGy; (4)standard feed, treated with BHA and irradiated to 5 kGy. Four groups each 10 mice were fed the fish feeds same as (1)-(4) for 14 days. There were no observable differences between fishs fed the irradiated feed and those fed the standard feed with respect to growth, feed consumption, haematology and organ histopathology Parameters. There were no deviations in feed consumtion, haematology and organ histopathology parameters in the experiment of mice. We concluded that there were no irradiation-related effects.

  • There are a number of reports on the pathologies of vestibular disorders. However, these studies included only a few examples, which were not quantitative but merely anecdotal or descriptive. However, a single tissue section may be relevant to a specific disease in multiple ways. The histopathological characteristics of common peripheral vestibulopathies, including benign paroxysmal positional vertigo, $M{\acute{e}}ni{\grave{e}}re^{\prime}s$ syndrome, labyrinthitis, vestibular neuritis, and ototoxicity, have been described. A recent study validated a new quantitative method for determining vestibular otopathology. Detailed quantitative analyses of vestibular pathology are required to obtain a deeper understanding of the vestibular system. Such studies will likely reveal the pathophysiological causes of specific diseases by elucidating the correlations between structural and functional features. Therefore, histopathological studies of vestibular disorders should be performed.

  • A 1-year-old castrated mixed-breed dog presented with diffuse, purple lesions arranged in an irregular patchy pattern, with a slight elevation on the right hindlimb extending from the tarsus joint to the upper region of the thigh. Dermatological examinations and fungal and bacterial cultures revealed no infectious agents. The therapeutic response to antibiotics and antifungal agents was negative. A histopathology examination of the lesion revealed vascular proliferation with vasodilation and numerous varying-sized vessels. Mast-cell-dominated perivascular cuffing was also noted. The dog was diagnosed with cutaneous angiomatosis due to diffuse lesions and the histopathology findings of hemangioma.

  • Histomonas meleagridis is a facultative anaerobic parasite, which can cause a common poultry disease known as histomoniasis. The species and age of the birds impacts on the susceptibility, with turkey being the most susceptible species. Chickens are less susceptible to H. meleagridis than turkeys and usually serve as reservoir hosts. Here, the diagnosis of an outbreak of histomoniasis in backyard Sanhuang chickens is described. The primary diagnosis was made based on clinical symptoms, general changes at necropsy, histopathology, and the isolation and cultivation of parasites. The pathogen was further confirmed by cloning, PCR identification, and animal inoculation tests. A strain of H. meleagridis, named HM-JSYZ-C, with a higher pathogenicity level in chickens was obtained. The study lays a foundation for further investigations into H. meleagridis and histomoniasis in chickens.
