T. verrucosum Infection has been reported for the first time in 1986 in Korea and has been increasing progressively. To evaluate the progress of clinical and histopathological change of dermatophytosis caused by T. verrucosum, inoculation study, using T. verrucosum isolated from infected human (human strain) and from infected cattle (cattle strain), was done in 24 male albino Hartley guinea pig. Their clinical and histopathological changes were evaluated. In addition, comparison for the growth rate between human strain and cattle strain on Sabouraud's glucose agar was made. The results were as follows: 1. Growth rate on Sabouraud's glucose agar: Cattle strain showed significantly more rapid growth rate than human strain on Sabouraud's glucose rate at 25℃ and 37℃. And cattle strain showed more rapid growth rate at 37℃ than 25℃. But human strain showed no significant difference of growth rate at both temperature. 2. Clinical findings: Initial erythema, scale and crust were developed about 8th after inoculation. All three findings reached maximum severity about 12th to 16th day and disappeared about 30th to 34th day after inoculation. There was no significant difference in progress of erythema, scale and crust between cattle strain and human strain. 3. Histopathological findings: Although mild acanthosis was noticed on the 3rd day after inoculation, the other findings including parakeratosis, intraepidermal abscess, spongiosis and vascular change, cellular infiltration were found on 9th day after inoculation. They reached maximum severity on the 12th day and lasted to the 25th day after inoculation. After that, all three findings were decreased gradually between 29th day and 33th day. On the PAS staining, hyphae and spores were found on the 6th day and disappeared on the 21th day after inoculation. 4. In trichophyton skin test, all of the 24 guinea pigs became positive within average 9.83±1.17 days These findings suggested that dermatophytosis caused by T.verrucosum induced rapid cell mediated immunity and contributed to rapid resolution of the lesion.

Notch stenosis had been thought to be related with anterior cruciate ligament (ACL) injury. The purpose of this study is to evaluate the possible relationship between notch stenosis and ACL injury. We measured the notch seen on the axial section in MRI at popliteal groove. We have retrospectively analyzed 116 cases of knee MRI. All cases were divided into three groups ; Group I were fifty six normal knee. Group II were thirty knee with contact ACL injuries. Group III were thirty knee with non contact ACL injuries. The result were as follows; 1. Statistically significant difference was found in the notch width index (NWI) between group I and group III but no significant differences was found in the NWI between group I and group II. 2. Statistically significant correlation to non-contact ACL injuries was found in the NWI at both anterior and posterior outlet of the notch. 3. An unique shape of the notch was found in the majority of group III.There seemed to be an obvious relationship between notch stenosis and non-contact ACL injuries.

OBJECTIVE: The purposes of this article are to present 5 cases of intracranial meningioma with leptomeningeal dissemination (LD) and investigate the characteristics of this disease. METHODS: We present a retrospective case series of 5 females at our institutions (age ranged 21-72 years, mean 54.6 years) diagnosed with LD of an intracranial meningioma after surgery between 1998 and 2013. A database search revealed 45 cases with LD of meningioma in the English literature. Characteristic features were analyzed and compared. RESULTS: The incidence rate at our institutions of LD of meningioma was 0.9% (5/534). World Health Organization (WHO) grade was distributed as follows: I : 2, II : 2, and III : 1. Time to LD ranged from 2.5 months to 6.9 years; the patient with WHO grade III had the shortest interval to LD. The patient with an intraventricular meningioma (WHO grade II) had the second shortest interval to LD (1.7 years), and simultaneously revealed both LD and extraneuronal metastases. Four of 5 patients showed a disease progression, with the survival ranging from 1 month to 3.8 years after LD. Based on the literature, the initial tumor was an intraventricular meningioma in 9 patients, and their time to LD was shorter on average (mean 1.9 years). Histologically, 26 of 45 (58%) were initially diagnosed with a WHO grade II or III meningioma, and 6 of 19 patients (32%) with WHO grade I revealed malignant transformation. CONCLUSION: This study shows that intraventricular location and histologically aggressive features seem to increase the chance of LD of meningioma.

BACKGROUND: Vascular endothelial dysfunction (VED) plays a pivotal role in the pathogenesis of atherosclerosis and is associated with insulin resistance and with visceral obesity. Therefore, in this study the predicting factor of vascular endothelial dysfunction was investigated in healthy premenopausal obese women by pulse-wave analysis (PWA) combined with provocative pharmacological testing. METHODS: Thirty three obese women (BMI> or =25), aged 20~45 y and 25 age-matched control subjects (BMI; 18.5~22.9) were examined. All women were sedentary (<1 hr/wk of physical activity), non-smoker and were excluded if they had type 2 diabetes melitus, hypertension, hyperlipidemia, cardiovascular disease, or acute inflammatory disease and were studied in folicullar phase of the cycle, within the first week after cessation of menstrual bleeding. They underwent determination of anthropometric measurements, metabolic variables, adipose tissue regional distribution, and endothelial function by performing pulse-wave analysis (PWA) combined with provocative pharmacological testing. RESULTS: Augmentation Index (AIx) fell significantly after the administration of salbutamol, which causes endothelium-dependent vasodilatation, but response was significantly reduced in obese women compared with controls (10.28 6.72% vs 17.2 6.84%, P=0.0003). The change in after Nitroglycerin, which causes endothelium-independent vasodilatation, did not differ significantly (30.86 9.67% vs 30.6 10.11%, P=0.9172). In our obese subjects, visceral adipose tissue area was independently a significant predictor of vascular endothelial dysfunction (beta= 0.1381, P=0.0038, Adj-R2=0.348). CONCLUSION: Increased abdominal adiposity is a powerful independent predictor of VED in obese healthy women. Future studies of vascular endothelial function should account for the independent effects of abdominal fat.
