Intracranial nerve sheath tumors unrelated to the cranial nerve roots are extremely rare, and the origin of the tumors are debatable. We report a case of pathologically-proven neurofibroma inside the lateral ventricle. A 49-year-old man presented with headache of 6 months duration, urinary incontinence, visual disturbance and right hemiplegia. Brain CT scan showed a well defined isodense mass with homogenous contrast enhancement and marginal calcification. At surgery the tumor was found to be a 4cm-sized lobulated mass attached only to the choroid plexus. Histologically, the tumor masses consisted of fasciculating bundles of wavy spindle cells, with a considerable collagen laydown.

Fingerprints have been used for personal identification, for revealing physical anthropological characteristics, and for diagnosing genetic disorders. Morphology of fingerprints has been analyzed in various tribes. However, in Korean, the analytical methods of fingerprints and the numbers of subjects were not sufficient to find standard values for Korean fingerprints. In this study, fingerprints of 3216 Koreans (2095 males and 1121 females) were analyzed using the various methods and compared with those of other tribes to contribute in revealing physical anthropological characteristics of Korean and also in diagnosing genetic disorders of Korean. The results were as follows. 1. The incidence of ulnar loop type, whorl type, radial loop type, and arch type was 50.4%, 42.9%, 3.8%, and 2.9%, respectively. Data from the comparison of the incidences of fingerprint types in Korean with those in various tribes lead us to conclude that Korean belongs to the Asians and becomes closer to the Whites and Blacks in which loop type is frequent and whorl type is not frequent. 2. Fingerprint type seems to be related to the strength of finger since whorl type was frequent in male and in right hand, and arch type was frequent in female and in left hand. In addition, loop of fingerprint appears to have the tendency to open to the side bearing more physical contact since radial loop type was frequent in second finger, and ulnar loop type was frequent in fifth finger. 3. Among the subtypes of fingerprint, morphologically simple types were common. Among the subtypes of arch types, simple arch type with the same number of radial dermal ridges as ulnar ones was the most common. Among the subtypes of loop types, ulnar loop type without concentric circles or spirals was the most common. Among the subtypes of whorl types, concentric whorl type without loops was the most common. 4. Finger ridge counts were 16.9, 13.9, 11.9, 11.3, and 11.2 in first, fourth, third, second, and fifth finger, respectively; and were greater in male than in female. Finger ridge counts are greater in fingers which shows whorl type. However, there would be other factors to determine finger ridge counts; for examples, the size and behavioral habit of finger.

1. The intracranial pressure (ICP) was raised by the extradural balloon method in urethane-anesthetized rabbits, and change of the arterial blood pressure (BP) with change of ICP was studied. 2. In the control rabbit group raising ICP resulted in marked increase in BP. 3. In the reserpine-treated group raising ICP did not induce the increase in BP but the decrease in BP. 4. In the tetrabenazine-treated group raising ICP did not cause change in BP. 5. After the administration of norepinephrine through the lateral ventricle to the reserpine-treated and tetrabenazine-treated rabbits, raising ICP resulted in marked increase in BP. 6. These results indicate that the existence of norepinephrine in the brain is essential for the BP increase by raising ICP.

Castleman's disease is a benign disorder characterized by hypervascular lymphoid hyperplasia. The etiology of the disease is still unknown. Although it may occur at the various sites such as peritoneum, retroperitoneum, pelvic lymph node, muscle and lung, it occurs most commonly at the mediastinum. Even though specific pathophysiologic relations are still not clearly determined between two different histologic types -hyaline vascular type and plasma cell type-, there were several previous reports dealing with the plasma cell type transformed or progressed into different types of malignancies such as malignant lymphoma, Kaposi's sarcoma and Hodgkin's disease. We experienced a case of plasma cell type Castleman's disease that transformed into a malignant lymphoma and report this case with review of literatures.

BACKGROUND: This study is aimed to elucidate the developmental pattern of human fetal lip by histological and immunohistochemical examinations. METHODS: Totally 231 normal human lip tissues obtained from autopsied fetuses were fixed with 10% buffered formalin, sectioned in cross and longitudinal directions, routinely stained for H&E and performed for immunohistochemistry with antibodies of S-100 protein, proliferating cell nuclear antigen (PCNA), transglutaminase C (TGase-C), metalloproteinase (MMP)-3, MMP-10, tenascin, KL1, K8.12, E-cadherin, tissue inhibitors of matrix metalloproteinase (TIMP)-1, TIMP-2 and total keratin (TK). RESULTS: The lip structure first appeared as an orifice of stomodeum around the 7-8th week of gestation, and a major structure of the midface was observed by the 11-12th week. As the squamous epithelium of the lip became thick and was keratinized, the vermilion border became distinguished in the 15-16th week, and the lip structure was almost completed with the presence of orbicularis oris muscle in the lingual side of vermilion border by the 17-18th week. Immunohistochemically, the vermilion border showed strong reactions for tenascin, E-cadherin and MMP-3 and increased positivity for PCNA, cytokeratins (TK, KL1, K8.12), and TGase-C. CONCLUSIONS: With the above findings we suppose that the cytodifferentiation of vermilion border epithelium plays an important role for the development of human fetal lip.

The motile marine bacterium, Vibrio vulnificus has a total of six flagellins. Flagellin is a structural component of flagellar filament in various locomotive bacteria and is the ligand of Toll-like receptor 5 (TLR5). TLRs, highly expressed on various types of cells including dendritic cells (DCs), recognize invading microorganisms and finally trigger host immune responses. In this study, we prepared all of six recombinant flagellin proteins and assessed the effect of six flagellins on IL-8 activation through TLR5 recognition. Although showed different activities, five out of the six flagellins stimulated significant IL-8 activation. We also investigated the immunomodulatory roles of Vv-FlaB, the crucial building block of V. vulnificus flagellar filament, on human dendritic cells. Treatment of immature DCs with Vv-FlaB resulted in an increased expression of co-stimulatory molecules and induced strong allo-T cell proliferative activities of the DCs. These results show that the Vv-FlaB may serve an epochal immune adjuvant possessing effective immunomodulatory activities.

OBJECTIVE: To correlate existing evaluation tools with clinical information on Duchenne muscular dystrophy (DMD) patients following age and to investigate genetic mutation and its relationship with clinical function. METHOD: The medical records of 121 children with DMD who had visited the pediatric rehabilitation clinic from 2006 to 2009 were reviewed. The mean patient age was 9.9+/-3.4 years and all subjects were male. Collected data included Brooke scale, Vignos scale, bilateral shoulder abductor and knee extensor muscles power, passive range of motion (PROM) of ankle dorsi-flexion, angle of scoliosis, peak cough flow (PCF), fractional shortening (FS), genetic abnormalities, and use of steroid. RESULTS: The Brooke and Vignos scales were linearly increased with age (Brooke (y1), Vignos (y2), age (x), y1=0.345x-1.221, RBrooke2=0.435, y2=0.813x-3.079, RVignos2=0.558, p<0.001). In relation to the PROM of ankle dorsi-flexion, there was a linear decrease in both ankles (right and left R2=0.364, 0.372, p<0.001). Muscle power, Cobb angle, PCF, and FS showed diversity in their degrees, irrespective of age. The genetic test for dystrophin identified exon deletions in 58.0% (69/119), duplications in 9.2% (11/119), and no deletions or duplications in 32.8% (39/119). Statistically, the genetic abnormalities and use of steroid were not definitely associated with functional scale. CONCLUSION: The Brooke scale, Vignos scale and PROM of ankle dorsi-flexion were partially available to assess DMD patients. However, this study demonstrates the limitations of preexisting scales and clinical parameters incomprehensively reflecting functional changes of DMD patients.

BACKGROUND/AIMS: Radiofrequency ablation (RFA) is an established curative therapeutic modality for unresectable hepatocellular carcinoma (HCC), and transarterial chemoembolization (TACE) has been used as a palliative treatment for inoperable HCC. It is still unknown whether RFA and TACE are equally effective for improving the survival of patients with unresectable HCC that is amenable to either treatment. The aim of this retrospective study was to compare the clinical impacts of two treatments, and analyze the prognostic factors for recurrence and survival. METHODS: Ninety-three patients with a single HCC smaller than 4 cm who showed complete responses (complete ablation or complete lipiodol tagging) after treatment with RFA (n=43) or TACE (n=50) between January 2002 and February 2009 were investigated. Univariate and multivariate analyses were performed for 13 potential prognostic factors using the Cox proportional-hazards model. RESULTS: The time-to-recurrence rates at 1, 2, and 3 years after treatment were 32.9%, 44.3%, and 55.4%, respectively, for the RFA group, and 42%, 68.3%, 71.7% for the TACE group. The probability of survival at 1, 2, and 3 years was 97.7%, 77.4%, and 63.1%, respectively, for the RFA group, and 95.9%, 76.1%, and 60.2% for the TACE group. The time-to-recurrence and overall survival rates did not differ significantly between the two treatment groups. A multivariate Cox proportional-hazards model revealed that a tumor size larger than 3 cm and lower serum albumin levels were independent risk factors for recurrence, and that being male, being seropositive for hepatitis B surface antigen, and having a higher serum albumin level were independent favorable prognostic factors for survival. CONCLUSIONS: TACE and RFA exhibited similar therapeutic effects in terms of recurrence and survival for patients with a single HCC smaller than 4 cm, if they could exhibited complete responses.

The upstream stimulatory factor 1 (USF1) gene has been shown to play an essential role as the cause of familial combined hyperlipidemia, and there are several association studies on the relationship between USF1 and metabolic disorders. In this study, we analyzed two single nucleotide polymorphisms in USF1 rs2073653 (306A>G) and rs2516840 (1748C>T) between the case (dyslipidemia or obesity) group and the control group in premenopausal females, postmenopausal females, and males among 275 Korean subjects. We observed a statistically significant difference in the GC haplotype between body mass index (BMI) > or =25 kg/m(2) and BMI <25 kg/m(2) groups in premenopausal females ( chi-square=4.23, p=0.04). It seems that the USF1 GC haplotype is associated with BMI in premenopausal Korean females.

The nephrotic syndrome in association with extrarenal malignancy is not an uncommon event. The membranous nephropathy is most frequently associated with various carcinomas of the lung, breast, stomach and colon. Though the exact causal relationship has not been determined completely, deposition of the immune complexes composed of antitumor antibody and tumor antigens in the subepithelium is most favorably accepted. We experienced a patient with previously diagnosed membranous nephropathy and subsequently demonstrated early gastric cancer during patient follow-up. After surgical resection proteinuria improved significantly. All physicians are strongly recommended to examine thoroughly and search carefully for possibility of concomitant occult malignancy when an aged patient, especially over 40 years old, is diagnosed as a nephrotic syndrome.
