This study was performed to investigate the effect of Perilla frutescens Herba extract on the treatment of chromaticity and colorfastness. Perilla frutescens Herba has been used as a Korean medicine. It is effective in removing dangerous for an unborn child and suppressing pain. It is also good as a detoxification and in treating cold. In the long history of Korea, dyeing has been applied for a means representing the grace of natural and inner esthetic consciousness of man. Vegetable dyes give us such great benefits, diversified color, but no pollution. And ramie fabric has distinctive features such as beautiful brilliance, elegance, and strong durability. So, it is regarded as a special product of Korea traditionally. These studies were carried out to treat with acetate iron, dichloride copper and alum with a mordant to ramie fabric. The ramie fabric was died with Perilla frutescens Herba extract. The results of experiment showed as follows: First, the chromophoric degree was the highest in acetate iron but not distinction in another mordants. Second, the light colorfastness was the highest in non treated and dichloride copper, but alum was the lowest. Third, the discoloration was alum and dichloride copper showed first grade in washing colorfastness. Abrasion colorfastness was not significant in this test. According the previous results, Perilla frutescens Herba has an efficiency in removing skin disorders and suppressing pain. So it considered that Perilla frutescens Herba can be applied effectively to theraphy of detoxification and in treating cold.

This paper proposed a framework for handover method in continuously tracking a person of interest across cooperative pan-tilt-zoom (PTZ) cameras. The algorithm here is based on a robust non-parametric technique for climbing density gradients to find the peak of probability distributions called the mean shift algorithm. Most tracking algorithms use only one cue (such as color). The color features are not always discriminative enough for target localization because illumination or viewpoints tend to change. Moreover the background may be of a color similar to that of the target. In our proposed system, the continuous person tracking across cooperative PTZ cameras by mean shift tracking that using color and shape histogram to be feature distributions. Color and shape distributions of interested person are used to register the target person across cameras. For the first camera, we select interested person for tracking using skin color, cloth color and boundary of body. To handover tracking process between two cameras, the second camera receives color and shape cues of a target person from the first camera and using linear color calibration to help with handover process. Our experimental results demonstrate color and shape feature in mean shift algorithm is capable for continuously and accurately track the target person across cameras.

Juvenile dermatomyositis is a common inflammatory muscle disease of childhood, characterized by weakness in proximal muscles and specific skin rash. In case of juvenile dermatomyositis without characteristic clinical features, non-invasive imaging tools such as $^{99m}Tc$-HDP three-phase bone scan are very helpful in diagnostic workup of myopathies. We report a case of 13-year old female with juvenile dermatomyositis, in which $^{99m}Tc$-HDP three-phase bone scan was useful in diagnosis and assessing therapy response.

A differential diagnosis between the true hermaphroditism (TH) and mixed gonadal dysgenesis (MGD) has important clinical implications for gender assignment and the decision for early gonadectomy; however, variable clinical and histological features frequently lead to the confusion of TH with MGD. A 17-month-old boy was presented with proximal hypospadias with chordee and right non-palpable testis in his scrotum. He also had right auricular anomaly including a separated tragus with skin tag. Left testis was well palpable in his left scrotum. Diagnostic right inguinal exploration showed Mullerian structures such as a gonad like an ovary and a fallopian tube with a uterus, which were removed. Repair of hypospadias and right auricular anomaly was also done. Following ultrasonography (USG) showed a normal looking testis in left scrotum. His chromosome was 45, XO/46, XY. We report a difficult case of mixed gonadal dysgenesis mimicking true hermaphroditism which combines ipsilateral congenital auricular anomaly.

Langerhans' cell histiocytosis is a rare disease showing proliferation of histiocytes in multiple organ system. Bone lesions are the most common radiolologic manifestation of Langerhans' cell hysticytosis. Extraskeletal sites of Langerhans' cell hystiocytosis involvement include the skin, lymph nodes, thymus, lungs, central nervous system, liver, pancrease, spleen, and bowel. The authors have experienced a case of Langerhans' cell histiocytosis which involved the skull. A 3-year-old female presented with soft tissue mass on right periorbital area. Plain skull X-ray showed punched out bone lesion. Computed tomography showed non-enhancing osteolytic lesion on right frontal skull. Histologic findings of an excised mass revealed pathologic features of Langerhans' cell histiocytosis.

Cutaneous leishmaniasis (CL) has been one of the most common parasitic diseases in Saudi Arabia. This study exhibits the clinical features, diagnosis, cytokine profile and treatment of CL patients in Al-Taif province. Ninety CL suspects at a tertiary care general hospital were enrolled in one-year study. Patients were interviewed, clinically-examined, and subjected to laboratory tests: skin scraping smear microscopy, OligoC-TesT commercial PCR (Coris BioConcept) and kinetoplast DNA (kDNA) PCR for Leishmania diagnosis. Interferon-gamma (RayBio; Human $IFN-{\gamma}$ ) and nitric oxide (NO) levels in patients' sera were evaluated before treatment with sodium stibogluconate (pentostam) with 20-day intramuscular drug regimen. Positive rates of microscopy, commercial PCR and kDNA PCR were 74.4%, 95.5% and 100%, respectively. Patients came to hospital mostly in winter (45.0%). CL was frequently exhibited in Saudi patients (78.8%), male gender (70.7%), age <20 years (50.0%), rural-dwellers (75.5%) and patients with travel history (86.6%). Lesion was mostly single ulcer (93.3%), occurred in the face (67.7%). Upon pentostam treatment, 85.1% of ulcers showed rapid healing signs. Levels of $IFN-{\gamma}$ and NO were significantly higher in the healing than the non-healing cases (P<0.001). The kDNA PCR proved more sensitive than microscopy and OligoC-TesT commercial PCR. Our results open perspectives for $IFN-{\gamma}$ use as a biomarker predicting treatment response.

Drug reaction with eosinophilia and systemic symptoms (DRESS) syndrome is a rare and severe drug-induced hypersensitivity syndrome characterized by hematological abnormalities and multiorgan involvement. Liver involvement is the most common visceral manifestation. However, renal failure has been rarely described. The common culprit drugs are anticonvulsants and allopurinol. We experienced a patient with DRESS syndrome with acute interstitial nephritis caused by concomitant administration of quinolone and non-steroidal anti-inflammatory drugs (NSAIDs). A 41-year-old man presented with a diffuse erythematous rash and fever which developed after administration of quinolone and NSAIDs for a month due to prostatitis. He was diagnosed with DRESS syndrome. Skin rash, fever, eosinophilia, and elevations of liver enzymes improved with conservative treatment and discontinuation of the causative drugs. However, deterioration of his renal function occurred on day 8 of admission. The levels of blood urea nitrogen and serum creatinine increased and oliguria, proteinuria and urinary eosinophils were observed. Ultrasonography showed diffuse renal enlargement. The clinical features were compatible with acute interstitial nephritis. Despite intravenous rehydration and diuretics, renal function did not improve. After hemodialysis, his renal function recovered completely within 2 weeks without administration of systemic corticosteroid.

본 연구는 최대하 부하 트래드밀 운동과 간헐적 부위별 인체 냉각 시 심부와 말초 부위의 동적 체온조절을 관찰하기 위해 고안되었다. 이를 위해 총 다섯명의 남자 피험자가 세 가지 실험 조건, 머리와 손 냉각 조건(HH cooling), 다리 냉각 조건(Leg Cooling), 냉각하지 않는 대조군(Control)에 참여하였고, 모든 실험은 기온 24±1℃와 습도 50±5%RH로 유지되는 인공기후실에서 수행되었다. 피험자들은80%HR_max의 트래드밀 운동과 이어지는 회복 스케쥴을 두 번 반복하였고, 인체 부위별 냉각은 15℃의 물이 순환하는 액체 냉각모자, 장갑, 다리를 덮는 형태의 담요를 이용하여 회복 시에만 적용되었다. 본 연구 결과, (1) 직장온도(T_re)는 세 조건 간에 유의한 차이를 보이지 않았다; (2) 피부온도는 부위별로 특징되어지는 다양한 체온조절 현상을 보였다. 특히, 운동의 시작 시점에서 보이는 피부온도의 초기 하강은 주로 가슴, 넓적다리, 종아리, 손가락 피부 온도에서 관찰되었으며, 이 중 손가락 온도(T_fing)에서의 초기 하강 현상은 매우 현저했다. (3) 피부 온도가 초기 하강을 보이는 동안 T_re는 점점 증가했다. (4) 두 번째 운동 시작 시 T_fing에서의 초기 하강 규모는 Control 조건에서 평균 4.8℃, HH cooling 조건에서는 5.1℃, Leg cooling 조건에서는 3.4℃로, 통계적으로 유의한 차이를 보였다(p<0.05). 초기 하강 현상을 보인 시간은 Control 조건에서 평균 8.1분으로 HH cooling 조건에서는 7.9분, Leg cooling 조건에서는 6.3분보다 길었으나 통계적 차이는 발견되지 않았다. 결론적으로, 트래드밀 운동의 개시기에 관찰된 피부온도 하강 현상은 인체 심부의 온열 상태의 진행과는 반대되므로, 비 온열적 요인을 반영한다. 특히, T_fing에서 초기 하강의 규모는 인체 부위별 냉각에 의해 영향을 받았다. 따라서, 말초 부위의 피부온도 하강 현상은 운동 중 피부면의 온열 상태 예측 시 주의깊게 고려되어져야 한다.

Primary nasal type natural killer (NK)/T cell (NKTC) lymphoma, a specific form of malignant lymphoma, has a higher geographic incidence in Oriental, Mexican, and South American populations than the Western population. In Koreans, it comprises 9-12% of all cases of non-Hodgkin's lymphoma. This type of lymphoma has also been named as angiocentic lymphoma and lethal midline granuloma because the most common site is the upper airway area and its clinical aggressiveness presents with a necrotic and destructive pattern. NKTC lymphoma can also be detected in different organs (testis, spleen, parotid gland, skin, gastroinstinal tract, central nervous system, lungs, bone marrow, etc.) other than the upper airway including the oral cavity. The lymphoma detected in the oral cavity shows various destructive and inflammatory changes, similar to the signs of inflammation and infection from periodontitis and pulpal disease, making a diagnosis difficult with just the clinical signs. For early detection, clinical, radiological, and pathological examinations are required. This report describes the clinical, radiological and histological characteristics with a case report for the early detection of NKTC lymphoma in the oral cavity.

The impulse of this paper is to examine the influence of unsteady flow comprising of Eyring-Powell nanofluid over a stretched surface. This work aims to explore efficient transfer of heat in Eyring-Powell nanofluid with bio-convection. Nanofluids possess significant features that have aroused various investigators because of their utilization in industrial and nanotechnology. The influence of including motile microorganism is to stabilize the nanoparticle suspensions develop by the mixed influence of magnetic field and buoyancy force. This research paper reveals the detailed information about the linearly compressed Magnetohydrodynamics boundary layer flux of two dimensional Eyring-Powell nanofluid through disposed surface area due to the existence of microorganism with inclusion the influence of non- linear thermal radiation, energy activation and bio-convection. The liquid is likely to allow conduction and thickness of the liquid is supposed to show variation exponentially. By using appropriate similarity type transforms, the nonlinear PDE's are converted into dimensionless ODE's. The results of ODE's are finally concluded by employing (HAM) Homotopy Analysis approach. The influence of relevant parameters on concentration, temperature, velocity and motile microorganism density are studied by the use of graphs and tables. We acquire skin friction, local Nusselt and motil microorganism number for various parameters.
