ABSTRACT
Aegle marmelos (Rutaceae) is a deciduous shrub or tree and typically known as bael throughout Southeast Asia and has been used as a medicinal plant and a food ingredient. In this study eight compounds were determined to be O-(3,3-dimethylallyl) halfordinol (1), (R)-aegeline (2), (R)-marmeline (3), imperatorin (4), xanthotoxol (5), valencic acid (6), vanillic acid (7) and rutin (8). The chemical structures of the isolates were elucidated through spectroscopic evidence including 1D, 2D NMR, ESI-Q-TOF-MS and optical rotation.
ABSTRACT
Purpose@#This study aimed to identify and compare the risk factors of depression among middle-class Korean workers. @*Methods@#A cross sectional study was designed for secondary data analysis. From the 8th Korean Medical Panel Survey (2008~2013), a total of 3,056 data was drawn and analyzed. With SPSS version 24, a developmental stage comparison, with the stage being young adults (20~39), middle-aged adults (40~64), and older adults (65+) were conducted. Frequency, percentage, x 2 test and logistic regression analysis were statistical tools used to analyze the data. @*Results@#In all developmental groups, experience of frustration was found to be a common risk factor of depression. Stress from excessive task, peer-compared subjective health status, and self-perceived social class were risk factors of depression in the young adults and the middle-aged adults. Anxiety for the future significantly influenced depression in the middle-aged adults and older adults. @*Conclusion@#Experience of frustration was a major risk factor of depression among Korean middle-class workers. Interventions to reduce depression need to be developed focusing on the specific risk factors by developmental stages such as experience of frustration, stress from task burden, poor peer-compared subjective health status and anxiety for the future.
ABSTRACT
Salvia plebeia R. Br. is a plant which has been used as an edible crop and traditional medicine in Asian countries. In this study, HPLC-PDA analysis and countercurrent chromatography (CCC) coupled with reversed-phase (RP) HPLC method were applied to isolate ten isolates from 3.3 g of n-butanol soluble extract from hot-water extract of S. plebeia. The use of CCC enabled us to efficiently fractionate the starting material with less sample loss and facilitate the isolation of compounds from S. plebeia extract using RP-HPLC. The isolates were determined to be caffeic acid (1), 6-hydroxyluteolin 7-O-β-D-glucoside (2), eudebeiolide B (3), (R)-rosmarinic acid (4), homoplantaginin (5), eudebeiolide D (6), plebeiolide C (7), salpleflavone (8), eupafolin (9) and hispidulin (10) based on the spectroscopic evidence.

ABSTRACT
Pilar sheath acanthoma is a rare, benign follicular hamartoma commonly affecting middle-aged and elderly individuals. It is characterized by a small, solitary, skin-colored papule situated on the head and neck, particularly around the upper lip. The lesion shares some features with trichofolliculoma and dilated pore of Winer, so it should be differentiated from these. Cytokeratin (CK) is a useful marker for studying the origin of epithelial tumors. We report a case of pilar sheath acanthoma which originated from outer root sheath using CK.

BACKGROUND: A venous lake lesion is a venous ectasia that occurs on the exposed skin of elderly people. Although a number of therapies such as surgical excision, laser therapy, infrared coagulation, cryotherapy and sclerotherapy have been used to treat venous lakes, there is no guideline for treating this lesion. OBJECTIVE: The purpose of this study was to determine whether 0.5% sodium tetradecyl sulfate (STS) is effective for the treatment of venous lake lesions. METHODS: Twelve patients with venous lake lesions were enrolled In this study. After proper antiseptic preparation, 0.5% STS was slowly injected into each subject's lesion, and this was followed by immediate compression for 10 minutes. RESULTS: After treatment, all of the patients' lesions cleared completely. The average number of treatments was 2.15+/-1.28. Two patients experienced mild side effects such as light pain and paresthesia, and these soon disappeared. There were no serious side effects reported during treatment. The mean follow up period was 29.58+/-13.48 months. CONCLUSION: We have demonstrated that sclerotherapy with 0.5% STS was quite effective for treating venous lake lesions, and this treatment caused no serious adverse effects.

Nevus lipomatosus cutaneous superficialis (NLCS) is a rare skin disease that is characterized by the ectopic presence of mature adipose tissue in the dermis. There are two clinical variants. The first type is multiple lesions with a zonal distribution, and this is usually seen on the buttocks or lower back area. The lesions are seen at birth or they develop within the first three decades of life. The second type is the solitary papule or nodule with a less restricted distribution and this occurs during the third to sixth decades of life. We report here on a case of a 13-year-old female who presented with an asymptomatic solitary 3x4 cm sized slightly erythematous elevated winkled mass on the right heel since birth, and the lesion gradually increased in size. The lesion showed the histopathological features of NLCS.

Angiomatoid fibrous histiocytoma is a rare soft tissue tumor, occurring predominately in children and young adults, with a low grade malignant potency. This tumor should not be confused with, and is not identical to, the aneurysmal fibrous histiocytoma of skin. We reported a case of a 6-year-old female who presented with an asymptomatic 1.5 cm x 1.5 cm sized erythematous nodule on the left knee of 3 years duration. The lesion showed a cystic tumor surrounded by fibrous pseudocapule in the dermis and subcutis and lymphoplasmacytic infiltrations in the pericapsular area. The tumor consisted of fibroblast-like and histiocyte-like cells and pseudovascular cysts. Clinical and histological findings led to the final diagnosis of angiomatoid fibrous histiocytoma.

Spiny keratoderma is a rare disorder and consists of multiple tiny keratotic plugs on the fingers and palms, which resemble the spines on a music box. Histopathologically, the lesions show compact columns of parakeratosis, with no granular layer beneath the column and no remarkable changes in the underlying epidermis and dermis. However, it is important to recognize that the disease is associated with internal malignancies. We report a case of spiny keratoderma in a 3-year-old girl, who had no associated underlying disorder.

Lichen planus is a lichenoid disorder characterized by shiny, flat topped papules. In addition to the classical appearance, there are several variants. Zosteriform lichen planus is a rare variant of lichen planus, which can be differentiated from linear lichen planus by not linear, but zosteriform distriburion. We herein present a case of zosteriform lichen planus in a 28-year-old man with pruritic, grouped, erythematous to brownish papules in zosteriform arrangement on the right flank for 4 months. He had no history of any previous skin disease.

BACKGROUND: Basal cell carcinoma (BCC) is the most prevalent cancer in the western world, showing a rapid increase in incidence. Activation of the Sonic hedgehog/Patched (PTCH) and is sisnalling pathway, due to PTCH inactivation, is a key event in sporadic and familial BCC development in humans and is associated with transcriptional activation of specific target genes, including GLI-1. Recently, PTCH inactivation by UV-specific mutation has been reported to develop BCC. OBJECTIVE: To evaluate the expression pattern of GLI-1 oncogene in BCC of sun-exposed and non-exposed areas of skin. METHOD: We examined 20 cases of BCC, and 4 cases of BCC occurring in sun-exposed and non-exposed areas, using an immunohistochemical method with paraffin-embedded sections. RESULTS: The results were as follows. 1. All cases of BCC showed a positive staining for GLI-1 protein. 2. In the staining pattern of GLI-1 protein, BCC in both sun-exposed and non-exposed areas showed diffuse staining throughout the tumor lobules. Moreover, the degree of staining was not found to be different between the BCC of sun-exposed and non-exposed areas. CONCLUSION: These results suggest that increased GLI-1 expression is important for BCC development. And multiple factors, including PTCH mutation due to UV irradiation, may affect GLI-1 expression.

We report a case of vitiligo developed on the sites of DNCB application for the treatment of alopecia areata in a 53-year-old woman. Histopathologic studies of the depigmented patches showed absence of melanin pigmentation at the basal layer of the epidermis and a negative reaction for the Fontana-Masson stain. The current theories explaining vitiligo development after topical sensitizer application are that topical sensitizers induce the vitiligo by a direct cytotoxic effect on the melanocytes, or by unmasking latent vitiligo as a result of the Koebner phenomenon due to contact dermatitis, but the exact mechanism is still unclear.

Annular pustular psoriasis is a rare form of psoriasis characterized by gyrate, annular lesions with an erythematous, scaly, pustular margin. Although usually generalized, in some instances it appears as a localized form. We herein report a case of annular pustular psoriasis localized to the penis of a 55-year-old man. He had a 5-year history of similar lesions on the same area, but there was no evidence of other cutaneous involvement.
ABSTRACT
Nevus sebaceus is a hamartoma that combines epidermal, follicular, sebaceous, and apocrine gland abnormalities. It mostly occurs on the scalp or face and shows characteristically well demarcated yellowish patches or plaque. Clinically several types of cutaneous neoplasms including syringocystadenoma papilliferum, basal cell carcinoma, nodular hidradenoma, syringoma, sebaceous epithelioma, trichilemmoma and apocrine neoplasms have been associated. We herein report a case of nevus sebaceus associated with tubular apocrine adenoma and apocrine poroma of a 11-year-old girl.

In the present study, the postnatal developmental changes in the expressional levels of cardiac sarcoplasmic reticulum (SR) Ca2+ regulatory proteins, i.e. Ca2+-ATPase, phospholamban, and Ca2+ release channel, were investigated. Both SR Ca2+-ATPase and phospholamban mRNA levels were about 35% of adult levels at birth and gradually increased to adult levels. Protein levels of both SR Ca2+-ATPase and phospholamban, which were measured by quantitative immunoblotting, were closely correlated with the mRNA levels. The initial rates of Ca2+ uptake at birth were about 40% of adult rates and also increased gradually during the myocardial development. Consequently, the relative phospholamban/Ca2+-ATPase ratio was 1 in developmental hearts. Ca2+ release channel (ryanodine receptor) mRNA was about 50-60% at birth and increased gradually to adult level throughout the postnatal rat heart development. 3[H]ryanodine binding increased gradually during postnatal myocardial development, which was closely correlated with ryanodine mRNA expression levels during the development except the ryanodine mRNA level at birth. These findings indicate that cardiac SR Ca2+- ATPase, phospholamban, and Ca2+ release channel are expressed coordinately, which may be necessary for intracellular Ca2+ regulation during the rat heart development.
