Atopic dermatitis is a common chronic inflammatory skin disease, associated with marked inflammatory cells (of mast cells and eosinophils) and severe itching, which leads to clinical problems in the pediatric population. This study was designed to investigate the inhibitory effects of luteolin liposome solution, that is entrapped the hydrophobic luteolin (one of the flavonoids) into ethosome to improve its stability, by using hapten-induced atopic dermatitis animal model (NC/Nga mice).The luteolin liposome treated mice showed anti-inflammatory effect as evidenced by the lowering of erythema and edema in clinical observation, reduction of inflammatory cell infiltration and epidermal thickness in histopathological examination, when compared with TNCB induced controls. Luteolin liposome solution also reduced the serum IgE level which played important roles in the atopic dermatitis model. These results suggest that luteolin liposome solution has some merit in this formulation showing inhibitory effects for the atopic dermatitis.

PURPOSE: The use of abdominal computed tomography (ACT) utilization is increasing to a remarkable extent in the pediatric Emergency Department (ED), but the clinical benefit of increased use of ACT for pediatric surgical patients remains uncertain. METHODS: A retrospective review was conducted to investigate if, for patients who had visited pediatric ED during the last 5 years, increasing utilization of ACT would increase the detection rate of acute appendicitis, increase the detection rate of surgical conditions other than appendicitis, and decrease the hospital admission rate for surgical conditions. RESULTS: During the study period, there were 37,918 ED visits; of these, 3,274 (8.6%) were for abdominal pain, 844 (2.2%) had ACT performed. The annual proportional increase of the ACT was statistically significant (1.56% to 2.46%, P = 0.00), but the detection rate of acute appendicitis (3.3% to 5.1%) or other surgical conditions (1.7% to 2.8%) showed no statistically significant changes. Hospital admission rates (5.6% to 6.8%) also showed no significant changes during the study period. CONCLUSION: Increasing utilization of ACT does not lead to the improved outcomes in caring for pediatric surgical patients visiting the pediatric ED. Careful evaluation for the indication for ACT is needed in the pediatric ED.

PURPOSE: Anal condyloma is an epithelial proliferative lesion caused by human papillomavirus (HPV) infection. The present study analyzed the HPV types detected in HIV (+) Korean anal condyloma using PCR-based DNA microarray. METHODS: DNA was extracted from the condyloma tissue of 17 patients including 9 HIV (+) patients (M:F=15:2, mean age 35 years, 22~59 years). The 1st PCR was performed with a general primer on L1 region, and nested PCR on the products of the 1st PCR. PCR products were hybridized with a DNA chip. RESULTS: Fourteen patients (9 HIV (+), 5 HIV (-)) showed positive HPV DNA. Overall, type 6 was the most common (N=11), and type 11 (N=6), type 53 (N=3) in order. Among HIV (+) patients, type 6 was also the most common (N=7), then type 11 (N=5) and type 53 (N=3). In contrast to the HIV (-) patients, 5 patients (55.6%) proved to have multiple infections in HIV (+) patients (2 double, 2 triple, 1 quadruple infection). Four of 9 HIV (+) patients (44.5%) showed co-infection with high-risk HPV. CONCLUSION: Multiple infection and co-infection with high-risk types are more prevalent in HIV (+) condyloma patients compared to HIV (-) patients. HPV types on HIV (+) male anal condyloma are similar to those detected in the Korean female uterine cervix.

PURPOSE: This study was intended to investigate the migrating motor complex (MMC) changes after ileal bypass in ex-vivo mouse models. METHODS: Partial (side-to-side) and total bypass (occlusion of proximal part of bypassed loop) were performed on ileums of female Institute of Cancer Research mice. After 2 and 4 weeks, the bypassed segments were harvested and MMCs were recorded at 4 different sites ex-vivo. Amplitude, duration, interval, direction of propagation, and the area under the curve (AUC) of MMCs were measured and compared to those of the controls. RESULTS: In control mice (n = 7), most MMCs propagated aborally (91.1%). After 2 weeks of partial bypass (n = 4), there was a significant decrease in both amplitude and AUC, and orally-propagating MMCs increased significantly (45%, P = 0.002). Bidirectional MMCs (originating in the bypassed loop and propagating in both directions) were also observed (10%). The amplitude of the MMCs remained decreased at 4 weeks after partial bypass (n = 4), and neither the AUC nor the direction of propagation showed significant changes compared to 2 weeks. Similarly, in the total bypass model, both the amplitude and AUC of the MMCs decreased significantly compared to controls. In contrast to partial bypass, 95% of the MMCs within the bypassed loop propagated aborally after 2 weeks (n = 6), which was similar to the control state. After 4 weeks (n = 5), however, MMCs either lost their temporal relationship or completely disappeared. CONCLUSION: The changes in propagation direction of the MMCs in the partially bypassed loop may contribute to stagnation of bowel contents and the development of blind loop syndrome.

After surgical operation in patients with arteriovenous malformation (AVM), normal pressure perfusion breakthrough (NPPB) is one of the major complications. Brain perfusion SPECT with acetazolamide stress was known to be useful to evaluate the vascular reserve in several neurological and neurosurgical conditions. The authors performed acetazolamide brain perfusion SPECT in patients with AVM and compared the brain perfusion in the post-operative clinical courses. The acetazolamide brain perfusion SPECT was helpful in defining the prognosis of the patients with AVM. We describe 4 patients with AVM who had acetazolamide brain perfusion SPECT to examine the prognosis.

PURPOSE: Protein tyrosine kinase(PTK), protein kinase C(PKC), oxidase, as a mediator, have been known to take a role in signal transduction pathway of angiogenesis. The authors confirmed that PKC is the most noticeable mediator for abnormal proliferation of vascular endothelial cells through in vitro study model using the inhibitors, targeting the formation of three co-enzymes. In this study, we would investigate which isoform of PKC play an important role in abnormal angiogenesis of vascular endothelial cell. METHODS: In 96 well plates, 10(4) HUVECs(human umbilical vein endothelial cells) were evenly distributed. Two groups were established; the control group without administration of DMH(1,2-dimethylhydrazine) and the DMH group with administration of 7.5x10(-9)M DMH. RNA was extracted from vascular endothelial cell of each group and expression of the PKC isoform was analyzed by RT-PCR(reverse transcriptase-polymerase chain reaction) method. RESULTS: RT-PCR analysis showed that PKCalpha, -betaI, -betaII, -eta, -micron and -zeta were expressed in vascular endothelial cells of each group. DMH incresed the expression of PKCalpha and PKCmicron, and decreased PKCbetaI, PKCbetaII expression dominantly. CONCLUSION: Based on the result of this study, it was suggested that PKCalpha and PKCmicron may have significant role in abnormal proliferation of vascular endothelial cell.

The propose of this study was to evaluate the effect of cellular activity of PDL cells dependent on intermittent and continuous compressive force by determining the alkaline phosphatase activity. An intermittent and continuous compressive forces were applied on PDL cells at the confluent stage. The alkaline phosphatase activity was measured on control and experimental groups every 24, 48, 72hours. The experimental group were consist of continous and intermittent compressive group which were compressed by 300g/cm2 of diaphragm pump. The intermittent compressive group was connected by timer which was worked on 10 minutes and off 10minutes. The results were as follow; 1. The alkaline phosphatase activity of intermittent compressive group was lower than control group at 24 hours(P<0.05). 2. The alkaline phosphatase activity between each groups showed no significant difference at 48hours. 3. The alkaline phosphatase activity of continuous compressive group was significantly higher than control group at 72 hours(P<0.01).
