배경: 악성종양에서 신생혈관 생성 및 당분해의 증가는 저산소 상태의 미세환경을 나타내며, 이는 종양의 침습성, 전이 등으로 환자의 예후와 관련이 있는 것으로 알려져 있다. Hypoxia-inducible factor 1(HIF-1)는 당원 수송체, 당분해 효소, 혈관내피세포 성장인자 등의 유전자의 전사를 활성화한다고 알려져 있다. 그리고 HIF-1의 전사 활성도는 HIF-1 a subunit의 표현이 조절되는 정도에 의존한다. 그러나 식도암에서 HIF-1의 발현과 혈관 생성능 및 종양세포 증식능과의 관계 및 예후에 관한 연구는 전무하다. 대상 및 방법: 고신대학교 의과대학 흉부외과학교실에서 1995년부터 2000년까지 수술치험한 77예의 식도 편평세포암 환자의 조직에서 채취한 정상 편평상피와 암조직에서 면역조직화학검사를 이용하여 HIF-1 a의 발현을 조사하고 혈관생성인자, 증식지수, p53 단백과의 상관관계, 임상-병리학적인 인자 및 생존율과의 상관관계를 분석하였다. 결과: HIF-1 a의 고발현율은 42.9% (33예/77예)였다. HIF-1 a의 고발현은 조직학적 등급(p=0.032), 병리학적 병기(p=0.002), 종양 침윤의 깊이(p=0.022), 주위 림프절 전이(p=0.002), 원격전이(p=0.049), 림프관 침윤(p=0.004)과 관련이 있었다. HIF-1 a의 고발현은 혈관내피세포 성장인자의 발현, Ki-67 증식지수와 관련이 있었으나, 미세혈관수와는 관련이 없었고, p53의 발현과는 관련이 있는 경향을 보였다. 단변량분석과 다변량분석에서 HIF-1 a의 고발현은 불량한 예후를 나타내는 인자로 보였다. 결론: 식도 편평세포암 조직에서 HIF-1 a의 발현은 종양조직내 신생혈관의 생성과 관련이 있는 것으로 나타났고, 고발현 된 경우는 림프절 전이와 수술 후 불량한 예후를 나타내었으므로 보다 강화된 치료전략이 필요할 것으로 사료된다.

유용 미생물로 선발한 Pseudomonas cepacia, Bacillus cereus 및 균근균을 인삼(Panax ginseng)근권에 처리한 후 이들 미생물들의 근권내 정착 및 근부병의 발생억제에 미치는 영향을 폿트 배양으로 실험하였다. P. cepacia의 단독 처리에서 처리 10일후에 근권에서 조사된 세균수는 6.26 (log cfu/g.soil)이나 B. cereus 등과 혼합 처리한 경우 $5.25{\sim}6.19(log\;cfu/g.soil)$으로 분포수가 적었고 처리기간이 270일 후에는 3.01 (log cfu/g. soil)으로 크게 감소하였다. Fusarium spp.의 근권내 분포수는 처리 $10{\sim}60$일 후에는 $3.33{\sim}3.67(log\;cfu/g.soil)$이었으나 처리 270일 경과 후에는 $3.33{\sim}1.02(log\;cfu/g.soil)$으로 크게 감소되었다. 근부병발생율에 있어서 대조가 4.3의 이병지수를 나타내나 P. cepacia 처리는 1.2로 발생이 크게 억제되었다. P. cepacia와 B. cereus의 혼합처리는 $1.8{\sim}2.3$의 이병지수로 대조 4.3보다는 병발생율이 낮아졌다. 균근균으로 Glomus albidum과 Acaulospora longular 처리는 병발생율 $1.2{\sim}1.6$으로 대조 4.3보다 감소하였다. 세균으로 P.cepacia와 균근균으로 G. albidum 처리는 근부율을 각각 1.2로 낮추는 발병억제 효과가 있다.

To describe the details of the foraminoplastic superior vertebral notch approach (FSVNA) with reamers in percutaneous endoscopic lumbar discectomy (PELD) and to demonstrate the clinical outcomes in limited indications of PELD. Retrospective data were collected from 64 patients who underwent PELD with FSVNA from August 2012 to April 2014. Inclusion criteria were high grade migrated disc, high canal compromised disc, and disc protrusion combined with foraminal stenosis. The clinical outcomes were assessed using by the visual analogue scale (VAS), Oswestry Disability Index (ODI) and modified MacNab criteria. Complications related to the surgery were reviewed. The procedure used a unique approach, using the superior vertebral notch as the target and performing foraminoplasty with only reamers under C-arm control. The mean age of the 55 female and 32 male patients was 52.73 years. The mean F/U period was $12.2{\pm}4.2$ months. Preoperative VAS ($8.24{\pm}1.25$) and ODI ($67.8{\pm}15.4$) score improved significantly at the last follow-up (VAS, $1.93{\pm}1.78$; ODI, $17.14{\pm}15.7$). Based on the modified MacNab criteria, excellent or good results were obtained in 95.3% of the patients. Postoperative transient dysthesia (n=2) and reoperation (n=1) due to recurred disc were reported. PELD with FSVNA could be a good method for treating lumbar disc herniation. This procedure may offer safe and efficacious results, especially in the relatively limited indications for PELD.

Objectives : Although surgical resection is used to treat meningeal hemangiopericytoma (MHPC), there is a high risk of subsequent recurrence. This study investigated factors associated with treatment outcomes and recurrence in patients who had undergone surgical resection of intracranial MHPC. Methods : Fifteen patients underwent surgical treatments performed by one senior neurosurgeon between 1997 and 2013. Clinical data, radiologic images, surgical outcomes, recurrence, and other relevant characteristics were reviewed and analyzed. Results : Fifteen patients were included in the analysis, 12 (80%) of whom had tumors in the supratentorial region, and 3 (20%) of whom had tumors in the infratentorial region. Complete resection was achieved in all 15 patients, and 3 (20%) patients were administered radiosurgery and conventional radiotherapy after surgery as adjuvant radiotherapy. Three patients developed recurrence, 2 of whom had not received adjuvant radiotherapy. In 1 of the patients who had not received adjuvant radiotherapy, recurrence developed at the original tumor site, 81 months after surgery. The other 2 recurrences occurred at other sites, 78 and 41 months after surgery. The 5- and 10-year overall survival rates were 88.3%, while the 5- and 10-year recurrence-free survival rates were 83% and 52%, respectively. Additionally the mean Ki-67 index differed significantly between patients who did and did not develop recurrence (43% vs. 14%; p=0.001). Conclusion : Because of the high risk of MHPC recurrence, MHPC tumors should be completely resected, whenever feasible. However, even when complete resection is achieved, adjuvant radiotherapy might be necessary to prevent recurrence.

Plasmablastic lymphoma (PBL) is a recently described aggressive B-cell neoplasm, which usually manifests as a localized disease of the oral mucosa in individuals infected with human immunodeficiency virus (HIV). Recently we encountered a case of plasmablastic lymphoma manifesting in the left maxillary sinus and cervical lymph node of a previously healthy HIV-negative man, 48 years of age. we conducted a fine-needle aspiration smear of the cervical lymph node, and this was found to be highly cellular with numerous large cells exhibiting eccentrically positioned nuclei, prominent nucleoli, and moderate quantities of basophilic cytoplasm. A biopsy of the mass in the maxillary sinus evidenced diffuse growth of similar plasmablastic cells. These tumor cells were negative for the leukocyte common antigens, CD20, CD3, CD30, and EMA. However, the cells tested positive for CD79a and CD138/syndecan-1. The tumor cells also exhibited L-light-chain restriction. The Ki-67 proliferation index was measured at almost 100%. The patient was diagnosed with plasmablastic lymphoma. After three cycles of combination chemotherapy and radiotherapy, the patient went into complete remission, and currently remains in this state.

Obesity markedly increases the risk of colorectal cancer. Recently, the preventive effects of edible mushrooms on triglyceride elevation and visceral fat accumulation have been reported. Here, the effects of Pleurotus eryngii (Eringi) and Hypsizygus marmoreus (Bunashimeji) on azoxymethane (AOM)-induced aberrant crypt foci (ACF; precancerous lesions) in the colorectums of mice fed a high-fat diet were examined. Eringi (ER) and Bunashimeji (BU) mushroom powder samples were used. Six-week-old male C57BL/6J mice received an intraperitoneal injection of AOM (10 mg/kg) once a week for two weeks, and were sacrificed and dissected at 6 weeks after the start of the experiment. After the initiation of the experiment, they received a normal diet (ND), high-fat diet (HFD), HFD + ER (1 or 5% of diet), or HFD + BU (1 or 5% of diet). As a result, body and fat weights were significantly lower in the 5% ER and BU groups than in the HFD group. Liver triglyceride levels were also significantly lower in the 5% ER and BU groups. Total liver cholesterol levels were significantly lower in the 5% ER group. The numbers of ACF (especially large ACF) showed strong inhibitory effects in both ER and BU groups. Measurement of the cell proliferation marker Ki-67 labeling index in the colonic mucosa demonstrated more significant suppression in both ER and BU groups than in the HFD group. These results suggest that the simultaneous intake of ER and BU may inhibit colorectal tumorigenesis in HFD-fed mice.

Background: Canine mammary gland tumors (CMGTs) are the most common tumor found in bitches. Changes in HER-2/neu genes in human breast cancer (HBC) lead to decrease in disease-free survival (DFS) and overall survival rate (OSR). Previous studies have demonstrated that the biological behavior of malignant mammary gland tumors (MMGTs) is similar to that of HBC. The present study aimed at evaluating the relationship between overexpression of HER-2/neu and clinicopathological features in MMGTs to represent a model of prognostic factors for HBC. Materials and Method: The clinicopathological data of 35 MMGTs were obtained. Immunohistochemical staining with HER-2, Ki-67 and CD34 markers was conducted with sections from paraffin-embedded blocks. According to standard protocols, histological type, grade, margin status, lymphovascular invasion (LVI), HER-2/neu score, proliferation rate and microvessel density (MVD) of tumors were determined and the association of HER-2/neu overexpression with these parameters was assessed statistically. Results: The IHC results showed that 12 (34.3%) cases were HER-2/neu positive. Statistical analyses indicated a significant relationship between HER-2 positivity and tumor grade (p=0.043), which also was demonstrated with cancer stage (p=0.035), tumor margin involvement (p=0.016), proliferation index (p=0.001) and MVD (p=0.001); however, there was no statistical relationship between LVI and tumor size. Overexpression of the HER-2/neu gene in MMGTs results in similar biological behavior as that of HBC; as a result, these tumors have can be considered to have important similarities in clinicopathological characteristics. Conclusions: MMGTs can be regarded as an HBC animal model. Further studies in this field would result in new treatments that could be beneficial for both dogs and humans.

Objective : Pleomorphic xanthoastrocytoma (PXA) is a rare primary low-grade astrocytic tumor classified as WHO II. It is generally benign, but disease progression and malignant transformation have been reported. Prognostic factors for PXA and optimal therapies are not well known. Methods : The study period was January 2000 to March 2012. Data on MR findings, histology, surgical extents and adjuvant therapies were reviewed in twenty-two patients diagnosed with PXA. Results : The frequent symptoms of PXA included seizures, headaches and neurologic deficits. Tumors were most common in the temporal lobe followed by frontal, parietal and occipital lobes. One patient who died from immediate post-operative complications was excluded from the statistical analysis. Of the remaining 21 patients, 3 (14%) died and 7 (33%) showed disease progression. Atypical tumor location (p<0.001), peritumoral edema (p=0.022) and large tumor size (p=0.048) were correlated with disease progression, however, Ki-67 index and necrosis were not statistically significant. Disease progression occurred in three (21%) of 14 patients who underwent GTR, compared with 4 (57%) of 7 patients who did not undergo GTR, however, it was not statistically significant. Ten patients received adjuvant radiotherapy and the tumors were controlled in 5 of these patients. Conclusion : The prognosis for PXA is good; in our patients overall survival was 84%, and event-free survival was 59% at 3 years. Atypical tumor location, peritumoral edema and large tumor size are significantly correlated with disease progression. GTR may provide prolonged disease control, and adjuvant radiotherapy may be beneficial, but further study is needed.
