Awareness effect of aquapuncture with dexamethasone on GV-26 was studied in tiletamine/zolazapam anesthetized six healthy crossbred dogs using a randomized cross-over experimental study design. After anesthesia by tiletamine/zolazapam, 0.1 mg dexamethasone was injected on GV-26 at 20 min in the experimental group. For the control group, 0.1 mg dexamethasone was injected on the quadriceps femoralis. A significant difference was evident in the sedation score between groups at 60 and 90 min (p < 0.05). A significant difference was also evident in the analgesia score at 50 and 60 min (p < 0.05). At 90 min, all dogs in the experimental group responded strongly to pain (p < 0.01). Head up time, sternal recumbent time, standing time, and walking time was shorter in the experimental group, but the difference from the control group was statistically significant only for head up time and walking time (p < 0.05). GV-26 acupuncture with dexamethasone is useful for awareness effects after anesthesia.

The prevalence of Toxoplasma (T.) gondii was surveyed using a latex agglutination test (LAT) in native Korean cattle. A blood sample was collected from female 105 cattle in the Daejeon area of Korea. All cattle were asymptomatic and had not received any prophylactic treatment for T. gondii. Blood samples were collected via the caudal vein. The cattle ranged in age from 2~6 years (mean 3.7 years). LAT detected antibody to T. gondii in four of 105 (3.8%) cattle. However, the hazard analysis and critical control point protocol has been applied to cattle farms and beef traceability has been strengthen.

Swine hepatitis E virus (HEV) has been reported as a new zoonotic agent due to its close genomic resemblance to the human HEV. Recently this virus is indicated as one of the important pathogens in xenotransplantation that uses pig as a donor animal. We carried out to investigate the prevalence of HEV infections among the pigs and human population in Chungnam region using a nested RT-PCR for detection of a part of HEV ORF2 gene. The sequences of the amplified DNA were analyzed and the genetical divergency were characterized. A total of 18 HEV strains, comprising 16 strains from pig and 2 strains from human, were genetically isolated from the fecal and serum samples. Among the isolates, 5 strains (2.5%) were detected from 200 swine sera and 2 strains (2.0%) from 100 human sera. All of the 16 swine strains were isolated from the pigs at 3 month of age, but none of age groups revealed the positive for swine HEV RNA. In comparison of the nucleotide sequence between 16 swine HEV and 2 human HEV isolates, the range of identities was 91.5% to 100%. Two human HEV isolates shared 99.7% homology. In phylogenetic analysis, all of the isolates were classified into genotype III, and the 18 isolates were also closely related to the prototype of swine HEV and human HEV strains isolated in the United States and others recently identified from swine in Japan and Netherland.

PURPOSE: Maspin is known as a tumor suppressor gene, but its significance has been questioned in various human cancers. The aim of this study was to investigate the expression pattern of Maspin in human gastric adenocarcinomas and its possible correlation with clinicopathological findings. MATERIALS AND METHODS: The expression of Maspin mRNA was measured by nested RT-PCR using 60 frozen adenocarcinomas of the stomach and 31 noncancerous tissues from the proximal resection margin. Immunohistochemical study for Maspin protein expression was carried out using 62 paraffin-embedded tissues, composed of both cancer and noncancerous tissues. RESULTS: Maspin mRNA expression was detected in 80.0% (48 of 60) of the gastric adenocarcinomas, but in only 22.6% (7 of 31) of the normal gastric mucosa (p<0.001). The positive rate of Maspin protein expression was higher in the adenocarcinomas than the normal tissues (62.9% vs. 27.4%, p<0.05). In addition, the intestinal type of tumors showed significantly higher expression levels compared to the diffuse type of tumors (81.5% vs. 48.6%, p<0.05). CONCLUSION: Our results suggest that Maspin is frequently expressed in human gastric cancers, and its expression might be associated with tumorigenesis of the intestinal type of gastric cancer.

Bone destruction is primarily mediated by osteoclastic bone resorption, and cancer cells stimulate the formation and activation of osteoclasts next to metastatic foci. Accumulating evidences indicate that receptor activator of NF-kB ligand (RANKL) is the ultimate extracellular mediator that stimulates osteoclast differentiation into mature osteoclasts. In contrast, osteoprotegerin (OPG) inhibits osteoclast development. In order to elucidate a mechanism for cancer-induced osteoclastogenesis, cells from a human breast cancer line, MDA-MB-231, were directly co-cultured with ST2, MC3T3-E1, or with primary mouse calvarial cells. Osteoclast-like cells and tartarate resistant acid phosphatase (TRAP) activities were then quantitated. We examined these cell lines and samples from breast cancer by RT-PCR for the expressions of OPG and RANKL mRNA. Compared to controls, co-culture of MDA-MB-231 cells with stromal or osteoblastic cells induced an increase in number of osteoclasts and TRAP activities. MDA-MB-231 cells alone or breast cancer samples did not express RANKL mRNA. However, co-culture of these cancer cells with stromal or osteoblastic cells induced RANKL mRNA expression and decreased OPG mRNA expression. These experiments demonstrate that direct interactions between breast cancer and stromal or osteoblastic cells induce osteoclastogenesis in vitro through modulating RANKL expression.

This study was performed to investigate whethere there is cross-reactivity between Dirofilaria immitis and three intestinal nematodes of dogs. In ELISA, D. immitis-infected dog sera obtained at the 4th molting stage (9-11 weeks) and microfilaremic stage (25-30 weeks) were shown to be highly reactive with crude extract of T. canis. In immunoblotting, some antigenic fractions, 44, 57, 88, 100 kDa of crude extract of T. canis, were found to be positive reaction with sera of dogs infected with D. immitis. However, little or no cross-reaction were observed between sera of D. immitis-infected dogs and crude extract antigen of T. vulpis or A. caninum. These result suggest that there are partial cross reaction between sera of D. immitis-infected dogs and the antigen of T. canis.

Squamous cell carcinomas (SCCs) of the head and neck are malignant tumors with their ability to invade and metastasis, which can affect the prognosis. The molecular pathogenesis of SCC of the head and neck is still not clear. Further understanding of the molecular alteration in SCC of the head and neck will be enable to provide more accurate and useful prognostic markers and more effective treatments. Maspin, a member of the serpin family of protease inhibitors, is known to have tumor-suppressor functions. However, association between its expression level and survival has not been demonstrated in Head and Neck cancer. Using the immunohistochemical technique to examine the expression levels of maspin in 30 cases of SCC in head and neck, the results showed that 73.3% of the cases expressed low to intermediate levels of maspin and 26.6% of the cases expressed high levels of maspin. The clinicopathological features of the SCC cases were also compared with the maspin expression level, and the results were that high maspin expression was significantly associated with the absence of lymph node metastasis. More importantly, higher maspin expression was significantly associated with better results of disease free survival time period, so it is suggested that high maspin expression may be a favorable prognostic marker for SCC of the head and neck.

BACKGROUND AND OBJECTIVES: Squamous cell carcinomas (SCCs) of the head and neck are known for their aggresive growth and propensity to metastasize, which often results in poor prognosis. Tumor cell interaction with the basement membrane has historically been viewed as the crucial step in tumor invasion and future metastasis. The invasive and metastatic process of malignant tumors requires the expression and activation of proteolytic enzymes which facilitate the progression of tumor cells in different ways. Among these proteolytic enzymes, collagenase-3 (matrix metalloproteinase-13) is a recently identified member of the MMP family, and is expressed in breast carcinomas and in articular cartilage from arthritic patients. The substrate specificity of MMP-13 is exceptionally wide as compared to other MMPs. MATERIALS AND METHODS: We performed immunohistochemical stains on 10 normal mucosas and 35 SCCs of the head and neck with anticollagenase-3 antibody and analysed the staining patterns. RESULTS: As a result, the expression of the MMP-13 were detected in 23 of the 35 SCCs (66%), but no expression was detected in any of the 10 normal mucosa. The expression of MMP-13 in most tumors was localized predominantly in neoplastic cells at the invading periphery of the tumor (74%;17/23). A significant correlation was found between MMP-13 expression and local tumor invasion but no correlation was observed between expression and the age, sex of the patients, histological grade, lymph node metastases, recurrence, or the stage of the tumors. CONCLUSION: These findings suggest that MMP-13 expression may contribute to the progression of a significant subset in SCCs of the head and neck. In the future, it is likely that elucidation of the regulatory mechanisms of the MMP-13 in SCCs may prove to be beneficial in developing novel therapeutic modalities for preventing invasion of these neoplastic cells.

A 26-year-old woman had an ovarian Sertoli-Leydig cell tumor (SLCT) associated with an elevated level of serum alpha-fetoprotein (AFP). The tumor had a heterologous element of intestinal-type mucinous epithelium, retiform and intermediately differentiated tubules of the Sertoli cells, and AFP-producing Leydig cells. AFP was demonstrated within the Leydig cells by an immunohistochemical technique. After surgery, the serum AFP level of the patient fell to the normal range. The present case is the first documented case of AFP producing a SLCT of the ovary reported in Korea.

Three dogs were experimentally infected with Dirofilaria immitis. All dogs were euthanised at 30, 36 and 37 weeks after inoculation of D. immitis for the recovery of adult worms. Three cases accounted to 42.91 % recovery of inoculated worms. Serum samples from dogs experimentally inoculated with D. immitis were analyzed by ELISA and immunoblotting methods. Antibody titers of dogs detected by ELISA peaked between 7 and 14 weeks then decreased between weeks 15 to 24 followed by another increase during weeks 25 to 30 and persisted throughout the remainde of the experiment period. Analysis of adult D. immitis protein stained with Coomassie brilliant blue R-250 indicated separately more than 10 bands, and the major bands were 22, 40, 46, 56, 70, 72 and 89 kDa. Antigenic identification of extracts antigens of adults D. immitis by immunoblotting analysis revealed several bands from pooled sera of patent infection (30 weeks after inoculation). The detected bands were 24, 70, 80 and 110 kDa, 22, 72 and 84 kDa, and 58 and 72 kDa in dogs 1, 2 and 3, respectively. Results of antibody titers reached high levels on the 4th molting stage after inoculation of infective larva (L3), and reinforced previous findings that high molecular weight regions are detected in young animals.

PURPOSE: There are increasing evidences that angiogenesis enhances tumor growth and biological aggressiveness in gastric carcinoma. Mast cells have been implicated in the angiogenic process, by secreting angiogenic factors including vascular endothelial growth factor (VEGF), or enzymes that degrade extracellular matrices. However, the exact nature of mast cells in relation to cancer is contradictory so we conducted retrospective studies, to find the significance of mast cell densities, and microvessel counts in each clinicopathologic factors, including VEGF expression, in proper muscle (PM) gastric carcinoma. MATERIALS AND METHODS: 52 specimens, obtained from patients with PM gastric carcinoma, were studied using the immunohistochemical methods, monoclonal antibodies for mast cell tryptase, factor VIII-related antigen and VEGF. RESULTS: Mast cell densities were significantly increased in diffuse histologic type (p=0.042), infiltrating margins (p3 cm (p=0.015), diffuse histologic type (p=0.038) and lymph node metastasis (p=0.001). Similarly there were significantly increased densities in VEGF positive tumors (p<0.0001). Pearson's correlation analysis revealed a significant relationship between mast cell densities and microvessel counts (r=0.614, p<0.01), indicating a high vascular grade with increased number of mast cells. CONCLUSION: We demonstrated a close relationship between mast cell densities, microvessel counts and VEGF expression. These results suggest that mast cells and VEGF are important regulators of tumor angiogenesis and cooperatively induce the formation of vascular stroma in PM gastric carcinomas.

We present a case of recurrent extraventricular neurocytoma with malignant glial differentiation in left temporoparietal area. A 37-year-old man with presentation of generalized seizure had undergone biopsy of brain tumor in left parietal area in 1987, which revealed extraventricular neurocytoma and radiotherapy was followed. Postoperative course was uneventful until eleven years after biopsy, when he became gradually aphasic and right hemiplegic. Brain CT and MRI revealed enlargement of tumor with peritumoral edema and calcifications. He underwent subtotal tumor removal in 1998. Microscopic examination of second biopsy specimen revealed presence of large areas composed of anaplastic glial cells with frequent mitosis, nuclear pleomorphism, large eosinophilic cytoplasm and eccentric nuclei, resembling gemistocytes, which were strongly immunoreactive to glial fibrillary acidic protein(GFAP) but not to synaptophysin(SNP). Also focal areas of neuronal cells were found, which were immunoreactive to SNP but not to GFAP. These histologic findings imply that this recurred tumor was a high grade, mixed tumor with divergent differentiation of neuronal and astrocyte lineage. We report a rare case of extraventricular cerebral neurocytoma with malignant glial differentiation with review of the literature.

PURPOSE: Breast cancer results from the progressive accumulation of a series of genetic alterations leading to neoplastic transformation. Recent studies have shown that a) HMGI proteins play an important role in the regulation of chromatin structure and function and b) the expression of aberrant HMGI [HMGI(Y) and HMGI-C] proteins is generally correlated with malignant tumors. We tried to define the function of HMGI in carcinogenesis and we compare the expression of HMGI with known clinicopathologic parameters. MATERIALS AND METHODS: Using Reverse transcriptase-polymerase chain reaction (RT-PCR), we determined the expression of HMGI mRNA in 60 primary malignant tumors, 20 normal tissue, 13 benign tumors, and four ductal carcinoma in situ. Immunohistochemical staining of p53, ER, PR, and clinicopathological parameters were evaluated. RESULTS: The expression of the HMGI(Y) mRNA increased more in malignant tissue (90%, 54 of 60) than in benign (76.9%) and normal (65%) tissues (p=0.031). The expression of HMGI-C mRNA was visible only in malignant (48.4%, 29 of 60) and benign (23.1%, 3 of 13) tumors. The expression of HMGI-C mRNA increased more in malignant tumors than in benign tumors (p<0.001). In invasive ductal tumors (n=50), the expression of HMGI-C mRNA was observed more in high grade tumors (grade 3~81.3%, grade 1, 2~32.4%) (p=0.005). Among the prognostic parameters, only the number of mitotic figures was related to the expression of HMGI-C mRNA (p=0.046). CONCLUSION: These results suggest that a) HMGI-C gene may be correlated with the formation of breast tumors and b) the expression of HMGI-C gene may be of pathogenetic and prognostic importance in human breast cancer.

Malignant mesothelioma occurs commonly in the peritonial cavity, pleural and pericardial cavity, also have been reconginzed in numerous other locations. However, it is rarely found in testis arised from tunica vaginalis. Aggressive surgery is necessary soon after diagnosis. Generally the prognosis is very poor and there is no consensus regarding treatment after surgery. We report a case of a 44 years old man with scrotal mass with recurrent pain for 2 years and pathologically diagnosed as a malignant mesothelioma in tunica vaginalis.

It suggested that localized fibrous tumor of the pleura originated from a primitive submesothelial mesenchymal cell. The criteria used for a judgment of malignancy were high cellularity and mitotic activity(more than four mitotic figures per 10 high-power fields), pleomorphism, hemorrhage, and necrosis. This 62 years female was admitted with dyspnea and cough. Chest X-ray and CT scan showed a huge mass in right thorax. A 23X18X12 cm, 2 Kg sized mass was excised, and it was collase the right lower lobe and right middle lobe and was adhered to the diaphragm. Pathologically, the tumor was composed high cellularity, fascicle of the spindle cells, and high mitotic numbers(27 mitosis/10HPF). Immunohistochemically, it was positive for vimentin and CD34. This tumor was diagnosised to the malignancy localized fibrous tumor. We experience a case of pleural malignant fibrous tumor and report this case with the review of literature.

PURPOSE: We performed this study to evaluate the value as early markers predicting the acute rejection and differential diagnosis with other causes of renal dysfunction. METHODS: Immunohistochemical stains for HLA-DR, ICAM-1, IL-2 and IL-4 were performed on 44 cases of implantation biopsies which were divided into cases with acute rejection (R group, 14 cases) and cases without rejection episode (N group, 30 cases), and 45 gun biopsies for renal dysfunction which divided into cases diagnosed as rejection (A group, 28 cases) and cases diagnosed as other causes rather than rejection (B group, 17 cases). We analysed immunohistochemical results, various clinical datas such as age and sex of donor, living or cadaveric status of donor, the mean number of HLA-DR mismatch, age and sex of patient, serum creatinine level at post op 2 day for implantation biopsy and at the day on biopsy for renal dysfunction between above groups. RESULTS: 1) In 44 cases of implantation biopsies, positive immunohistochemical stains for HLA-DR were more frequent in R goup (71.43%) than in N group (26.66%). There was no significant difference of clinical datas and immunohistochemical stains for ICAM-1, IL-2 and IL-4. 2) In 45 cases of gun biopsies for renal dysfunction, immunohistochemical stains for HLA-DR were all positive in A group (100%) with higher rate of 3 stains (39.28%) than B group (positive; 70.58%, 3 ; 5.88%). Immunohistochmical stains for ICAM-1 were more frequently expressed in A group (100%) than B group (76.47%). Both stains revealed no significant difference according to the grades of rejection, disease other than rejection. There was no significant diffrence of immunohistochemical stains for IL-2 and IL-4, and clinical datas between two groups. CONCLUSION: We can conclude that the immunohistochemical stains for HLA-DR on implantation biopsies may predict the devepoment of the acute rejection and the immunohistochemical stains for HLA-DR and ICAM-1 on gun biopsies at the time of renal dysfunction may differentiate the reje.

Amyloid goiter is a rare disease entity that is defined as a symptomatic mass or clinically detectable thyroid enlargement because of amyloid deposition. We present a case of amyloid goiter diagnosed in the fine needle aspiration cytology(FNAC) in a 73-year-old Korean woman presented with nephrotic syndrome and thyroid enlargement. The thyroid function was in normal range. Thyroid scan showed a nodule, 4x2 cm in the right lobe with underlying diffuse goiter. Aspirates revealed benign looking follicular cells and scattered eosinophilic material. The sections of the cell block showed nodular deposit of eosinophilic hyalinized material in the interfollicular area. It showed apple-green birefringence under polarization with Congo red stain. The renal biopsy also exhibited deposition of eosinophilic materials in the glomeruli and interstitial vascular wall, which were confirmed as amyloidosis. This material was morphologically distinct from the colloid.
