  • The purpose of present study is to observe the hepato-protective effect of ginger aqueous extracts on carbon tetrachloride($CCl_4$)-induced mouse. Ginger groups received ginger aqueous extracts (500 mg/kg) orally for 3 days and given a single dose of $CCl_4$ (4 mL/kg). Silymarin group was treated with silymarin (50 mg/kg) orally for 3 days and then aministration of $CCl_4$ (4 mL/kg). Control group was only administered $CCl_4$ (4 mL/kg). In the ginger groups, the AST, ALT levels were significantly (p < 0.05) decreased compared to the control groups. Histopathological evaluation, hepatic parenchyma and kidney parenchyma of ginger groups were significantly (p < 0.05) decreased compared to control group. The results obtained in this study suggest that ginger aqueous extracts are able to protect the liver $CCl_4$-induced injury.

  • We investigated the systemic effects of leaf folder (Cnaphalocrocis medinalis) resistant rice (transgenic rice, Nakdongbyeb) in Sprague-Dawley rats for 13 weeks. Leaf folder resistant rice was added to the diet at percentage levels of 0, 5 and 20 percentage/feeder and was administered for 13 weeks. The results did not show any changes in food and water intake. There were also no biologically significant changes in both body and organ weights, hematological and blood biochemical parameters, autopsy and histopathology between the treatment and control groups. Based on these results, no observed adverse effect level (NOAEL) of transgenic rice was considered to be more than 10,000 mg/kg b.w. under the conditions of the present study.

  • We present a case of a 47-year-old woman with benign solitary fibrous tumor of the pleura originated in the diaphragm which was discovered incidentally on a chest radiograph. Chest radiograph, sonograph, computed tomographic scan and magnetic resonance image studies proved a well circumscribed and lobulated fibrous tumor of the pleura. During the subsequent right thoracotomy, the tumor was found to be encapsulated and consisted of firm mass. It was connected to the diaphragm with $5{\times}4$cm area by pedicle. Most of the tumor was free of adhesion. It was excised completely together with attached diaphragm. The tumor measured $23.5{\times}13.5{\times}8.0$cm and the pathologic diagnosis was benign solitary fibrous tumor and the attached diaphragm was free of disease.

  • The expression of sex steroid hormone receptors by neoplastic cells is an important predictor of response to hormone therapy. Thus, the selection of treatment modality is often based on the identification of receptors in tumor tissue. Various monoclonal antibodies of high specificity are now available for analyzing the estrogen receptor (ER). With these antibodies, biochemical enzyme immunoassay and immunohistochemistry using histologic sections have been used for ER analysis. We used fine needle aspirates from 15 human primary breast carinomas for the analysis of ERs. The semiquantitative receptor values obtained in cytologic specimens were correlated well with those from histologic specimens. The results of ER in fine needle aspirates were concordant with ER in histologic specimens(r=0.94). Only three cases showed a little difference in staining intensity and proportion of positive cells. Our results showed a good correlation between the receptor values determined in cytologic smears and those determined in tissue sections. It is suggested that measurement of the ER in cytologic smears may be a reliable technique which can be performed on aspiration cytologic samples.

  • A 5-year-old, female Poodle and her daughter, 2-year-old, were referred to Konkuk University Veterinary Teaching Hospital (KVTH) due to discoloration of hair on dorsum, and generalized alopecia following clipping. Some papules and pustules are found on patch area. Complete blood counts and serum chemistry profiles were not remarkable. Trichogram revealed that melanin-granule was pigmented on hair bulb and shaft in affected area and no melanin pigmentation was noted in non-patch area. And skin biopsy showed mild epidermal hyperplasia and mild inflammation in dermis of the patch area. This case report indicates that melanotrichia can be occurred by postclipping inflammation. However, the mechanism of melanocyte proliferation and rates of melanogenesis in response to postclipping remains to be unclear in these cases.

  • The antiobese effects of Allium victorialis (AV) leaf methanol extract were evaluated in a high fat diet (HFD) supplied mice. The changes on the body weight, food consumption, leptin and adiponectin levels as well as the periovarian fat weights and histopathology of adipocytes were examined. The effects were compared with those of a group given 250 mg/kg of metformin. After 91 days of a continuous HFD supply, the mice were significantly showed obesity. However, the obesity induced by the HFD was inhibited by the AV extract treatment at the three different doses (62.5, 125 and 250 mg/kg) respectively. The results suggest that the AV methanol extract is beneficial for improving the diet-induced obesity in humans.

  • In 2014, high mortality was observed in olive flounder (Paralichthys olivaceus) during experimental infection. Diseased fish did not show any outward clinical signs, but numerous fungal hyphae were detected in the gills. No parasites or bacteria were isolated from the diseased fish. A high mortality rate (100%) resulted when cohabitation with fungi-infected fish were applied to healthy fish. The affected fish exhibited sever fungi infection in the gills. Histopathological examination revealed numerous fungal hyphae and mycelium around gill filament, lamellar and racker. These results suggest that the fungi may be related with the mortality of olive flounder.

  • The authors present the fine needle aspiration cytology (FNAC) cytologic findings of a case of extranodal marginal zone B cell lymphoma (MZBCL), which featured abundant plasma cells and eosinophilic histiocytes arising in both parotid glands. A 49-year-old female presented with palpable masses in both parotid glands. She had been suffering from systemic lupus erythematosus and rheumatoid arthritis. The lesions were evaluated by FNAC and smears showed a small number of clusters of oncocytic cells with abundant eosinophilic granular cytoplasm and small nuclei, intermixed with small to medium-sized lymphoid cells containing round to lobulated nuclei, which suggested Warthin's tumor. Some of lymphoid cells had a plasmacytoid appearance, and some scattered large cells contained a large amount of eosinophilic cytoplasm. Bilateral superficial parotidectomy was performed and a histopathologic study indicated MZBCL with abundant plasma cells, intermixed with eosinophilic histiocytes. The presence of oncocytic cells and a mixture of lymphoid and plasma cells indicates Warthin's tumor, but the cytologic features of a relatively monotonous small to medium-sized lymphoid infiltrate suggest the possibility of MZBCL in the clinical setting of an FNAC study performed on a patient suffering from a connective tissue disease.

  • A 32 year-old man was transferred to our hospital due to blood-tinged sputum for 15 days. He had been treated at a private hospital for recurrent pneumonia. The chest X-ray showed an atelectasis on the right middle lobe. Computed tomography of the chest demonstrated a broncholith on right middle lobar bronchus with lobar atelectasis of the right middle lobe. We tried to remove the broncholith through fiberoptic bronchoscopy, but could not remove it. Therefore, we performed surgical removal of broncholith and the right middle lobectomy. The cause of broncholith was identified as actinomycosis by pathologic examination. The broncholith caused by actinomycosis is rare. We report a rare case of broncholithiasis with recurrent obstructive pneumonia caused by actinomycosis, which was treated by surgical operation.

  • Hemangiomas of mediastinum are rare lesions comprising less than 0.5% of all mediastinal masses. Posterior mediastinal hemangiomas are less common than anterior mediastinal. A 21 year old female was refered to our hospital because of abnormal mediastinal shadow in simple chest X-ray. Chest CT scan and T-spine MRI revealed a posterior mediastinal dumbbell-shaped mass with extradural extension. Surgical excision was performed and pathologic diagnosis was confirmed as 3${\times}$4${\times}$2 cm sized capillary hemangioma.
