Dermatophytes infect the human hair, skin, nail and cause the dermatophytosis. The extracellular and intracellular proteinases of the dermatophytes commonly occur in the genus Trichophyton like T. rubrum, T. mentagrophytes, and T. granulosum. These enzymes play a prominent role in growth, multiplication and infection of the host tissue. Extracellular proteinases have been purified from the species of Trichophyton and Microsporum. We purified the proteinase partially from the culture filtrate of the Trichophyton tonsurans through Mono-Q and Superose 12 column and investigated its biochemical and enzymatic characters. The molecular size of the proteinase was estimated to be 41 kDa by SDS-PAGE. And pI was 3.2. The optimal temperature and pH for an enzymatic activity were 27C and 7.5, respectively. The purified porteinase degraded the keratin, bovine serum albumin, hemoglobin. The serine proteinase inhibitor like PMSF and DFP inhibited the proteolytic activity of the purified enzyme whereas the cysteinase inhibitor did not. These results demonstrated that the purified proteinase is a serine proteinase and can contribute the tissue invasion.

Duchenne muscular dystrophy (DMD) is the most common and lethal dystrophy in childhood, caused by mutations in the dystrophin (DMD) gene. Multiplex ligation dependent probe amplification (MLPA) or array comparative genome hybridization (aCGH) is widely used as an initial molecular diagnostic tool. If no deletions or duplications are found in MLPA or aCGH, the samples must be subjected to a second test of direct sequencing. Direct sequencing of the DMD gene, however, is time-consuming, high-cost, and can be inconclusive. Here, we performed whole exome sequencing on a patient with progressive muscle weakness whose MLPA result was negative; the result revealed a rare frame shift mutation. Direct sequencing on the patient's mother showed the same mutation. Whole exome sequencing can be a new diagnostic routine for DMD patients with negative MLPA3.

This study was undertaken to investigate the characterization and distribution patterns of MHC class II positive dendritic cells[DCs] and ED2 positive tissue macrophages throughout the estrous cycle and during pregnancy in the rat ovary. The immunohistochemical characterization of the cells was carried out using the monoclonal antibodies OX6 and ED2 in cryostat-cut sections. DCs were distributed in the theca cell layer of the growing and mature follicles,stroma and corpus luteum. Tissue macrophages were distributed in the theca externa of the growing and mature follicles, stroma and corpus luteum but they were smaller in number than DCs. None of DC and tissue macrophage was found in the ovum, granulosa layer and follicular cavity of the ovarian follicle. However, DCs and tissue macrophages were present in the granulosa layer and follicular cavity in the atretic follicles. Degenerating corpus luteum contained a vast number of OX6 positive cells. On the contrary, fewer tissue macrophages were founcl in the degenerating corpus luteum. More macrophages tended to be observed in the former follicular cavity and theca lutein cell layer than in the granulosa lutein cell layer of the corpus luteum. In stroma,DCs and tissue macrophages were more frequently found around the blood vessels than in the other region, however, DCs were relatively greater in number than tissue macrophages. There was no estrous cycle and pregnancy dependent variation in the numbers and distribution patterns of DCs and tissue macrophages. In conclusion, the rat ovary contains rich networks of MHC class II positive dendritic cells and ED2 positive tissue macrophages. These findings suggest the existence of a well-developed system of immunological surveillance in the rat ovary. The results of this study have potentially important implications for the understanding not only of the ovarian immune system and the pathogenesis of various ovarian diseases but also of various physiologic functions of the ovary.

PURPOSE: To investigate the results of Advanced Surface Ablation (ASA) coupled with "smoothing" to smooth the ablation surface after covering masking fluid. METHODS: ASA was performed in 61 eyes with ablation depth of more than 75 microm. The mean refractive error was -5.88 +/- 1.27 D and mean ablation depth was 102.93 +/- 12.06 microm. Smoothing was performed in all patients (mean depth 16.79 +/- 2.43 microm, mean diameter 8.77 +/- 0.16 mm). Customized Aspheric Transition zone (CATz) was used in the laser algorithm. RESULTS: The mean refractive error was -0.29 +/- 0.41 D at postoperative 6 months and 97% of patients had an UCVA of 1.0 or better at postoperative 6 months. There was no statistically significant difference in magnitude of high-order aberrations at postoperative 6 months. The magnitude of total spherical aberrations increase was 0.084 microm at postoperative 6 months (p<0.05, paired t-test). The cornea was maintained clear in the majority of eyes. CONCLUSIONS: Excellent results were obtained by ASA coupled with "smoothing" in high myopia patients with an ablation depth greater than 75 microm.

Objectives: The diagnosis of hypersomnia may be changed by the repeated multiple sleep latency test (MSLT). We investigated the long-term reliability of MSLT in the diagnosis of narcolepsy type 1(NT1) and 2 (NT2). Methods: We reviewed the data of patients with NT1 and NT2 who underwent MSLT at least twice between 2008 and 2020. The clinical information and polysomnography/MSLT data were thoroughly assessed, and two sleep experts evaluated the consistency and reliability of diagnosis independently. Results: Eighty patients (38 with NT1 and 42 with NT2 as a final diagnosis) were included in this study. Of the 80 patients, 20 (nine with NT1 and 11 with NT2) underwent the 3rd MSLT. No significant differences were found in the sleep data and Epworth Sleepiness Scale at baseline. During the 2nd MSLT, 18.4% (n=7) patients with NT1 and 47.6% (n=20) patients with NT2 did not satisfy the diagnosis of narcolepsy. At the 3rd MSLT, six out of nine patients with NT1 and seven of 11 patients with NT2 were not suitable for narcolepsy. Two of the initial NT1 (5.2%) and 10 of the initial NT2 (23.8%) patients were found to be normal. Three patients who were confirmed to have NT1 through consecutive MSLTs had significantly shorter sleep latency and more number of sleep-onset rapid eye movements than the other patients. Conclusions The reliability of MSLT were not robust in the diagnosis of NT1 and NT2 in this long-term follow-up study. The MSLT results should be interpreted with careful consideration based on elaborate preparations.

Objective: The purpose of this study was to evaluate the effects of adding music therapy (MT) to cognitive-behavioral therapy (CBT) on symptoms of smartphone/internet addiction and psychiatric comorbidities. Methods: Overall, 155 patients diagnosed with addiction were assigned to either the CBT-MT group or CBT group. Both groups received CBT for 8 weeks, while the CBT-MT group received additional MT. The intervention was completed by 67 and 71 participants in the CBT-MT and CBT groups, respectively. Results: The total scores of Young Internet Addiction Scale (YIAT) and Smartphone Addiction Proneness Scale (SAPS) decreased significantly (p<0.001 for both) in both groups, while the total scores of State Anxiety Inventory for Children (SAIC) (p<0.001), Trait Anxiety Inventory for Children (TAIC) (p<0.001), Conners-Wells’ Adolescent Self-Report Scale-Short form (CASS(S)) (p=0.048), and Barratt Impulsiveness Scale-11 (BIS-11) (p<0.001) decreased only in the CBT-MT group. The decrements in YIAT (p=0.025), SAIC (p=0.043), TAIC (p=0.011), and BIS-11 (p=0.012) in the CBT-MT group were significantly greater than those in the CBT group. Conclusion Combined MT and CBT improved the symptoms of smartphone/internet addiction, anxiety, and impulsivity in adolescents. This combination could therefore be an effective treatment of smartphone or internet addiction along with behavioral disorders such as anxiety and impulsivity.

The authors analyzed ultrasonographic findings of 112 cases of trophoblastic disases which were confirmed byD&E or hysterectomy at Wallace Memorial Baptist Hospital from September 1980 to December 1984. The results were asfollows; 1. Of all 112 cases, hydatidiform moles were 99 cases, invasive moles were 3 cases and choriocarcinomas were 10 cases. 2. 81 cases (72%) occurred in 3rd decades. 3. The sized of uterus was large for gestational weeksin 65 cases(56%) and smaller in 13 cases(13%). 4. The contour of uterus was globular in 59 cases(53%), diffuse in49 cases(44%) and nodular in 4 cases(3%). 5. The internal echopatterns of uterus revealed numerous small vesicular snowstorm patterns in all cases, and revealed internal degeneration in 67 cases(60%). 6. Uterine walls in 89 cases(79%) were well delineated but uterine walls in 23 cases(21%) were poor delineated. 7. Multiseptated ovarian thecalutein cysts were seen in 36 cases (32%). 8. Invasive trophoblastic disease(invasive moles 3 cases andchoriocarcinomas 10 cases) revealed similiar ultrasonographic findings with H-mole, but more irregular internalechoes and irregular echoes in uterine wall. 9. Diagnostic accuracy was diagnostic in 98 cases (88%) , nonspecificin 11 cases (10%) and error in 3 cases(2%).
