Objective : The purpose of this study is to report the hair regrowth effect of Gagamyeonryunggobon-dan on ICR mice from measuring the change of diverse factors.Methods : Gagamyeonryunggobon-dan was treated by oral administration with 2.5㎎/㎏/day amount for 3 weeks per mouse everyday. Hair regrowth was estimated by change of morphology, angiogenesis, hair follicle activation. The change of morphology was observed with external, internal change and sebaceous gland. Angiogenesis was estimated by image analysis, capillary distribution and angiogenic chemokine(MIP-2). Hair follicle activation was estimated by PCNA, IGF-2 and serotonin.Results : 1. Gagamyeonryunggobon-dan treated group had more and thicker hairs than the group not treated. Especially well developed sebaceous glands were seen in dermis of treated group. 2. Gagamyeonryunggobon-dan treated group had more capillaries near hair follicles of subcutaneous layer and more 2019% MIP-2 positive activity than the group not treated. 3. Gagamyeonryunggobon-dan treated group increased positive activity up to 596% in PCNA, 187% in IGF-2 and 547% in serotonin more than the group not treated.Conclusion : These results shows that Gagamyeonryunggobon-dan have the hair regrowth effect through verifying change of morphology, angiogenesis, chemokines. Consequently Gagamyeonryunggobon-dan is expected to apply to take care of extensive hair loss symptoms.

Tests of stability and toxicity, and clinical evaluation of anti-acne activity suggest that cryptotanshinone, a constituent of the roots of Salvia miltiorrhiza Bunge, is an effective active ingredient for acne vulgaris treatments. Acne vulgaris, called acne or pimples, is the most common disease of the pilosebaceous follicle unit of the skin. It affects nearly 80% of people between the ages of 11 and 30. Approximately 30% of teenagers have acne of sufficient severity to require medical treatment. Acne is a follicular disorder of the skin. It occurs in specialized pilosebaceous units on the face and body. Acne develops when these specialized follicles undergo pathologic alterations that result in the formation of non-inflammatory lesions (comedones) and inflammatory lesions (papules, pustules and nodules). An abnormality of keratinizing epithelium of these follicles, thought to be due to the action of sebum synthesized and secreted by the androgen-sensitive sebaceous glands, leads to inflammation induced by the follicular bacterium Propionibacterium acnes. Therapy involves treatments that modify these pathogenic factors and includes drugs with antikeratinizing, antibacterial and antiseborrheic actions. Acne vulgaris is a very frequent disease, seen primarily in adolescents, involving the sebaceous follicles. Acne vulgaris is characterized by a great variety of clinical inflammatory and non-inflammatory lesions: comedones, papules, pustules, nodules, cysts and scars. Acne vulgaris is a multi-factorial disease. Although its pathogenicity is unclear, extensive studies have shown that hyperseborrhea, superinfection by P. acnes and endocrinologic androgenic changes play a role in the development of acne vulgaris.

The fuzzy rat that expresses hypersecretion of sebum and hyperplastic sebaceous glands is a genetic mutant for the study of many pharmacological aspects especially human acne. Through this model, we examined the effects of several phospholipids on the secretion of sebum after topical application. The phospholipid derivatives were phosphatidylcholine (PC), hydrogenated phosphatidylcholine (HPC), phosphati dylserine (PS) and hydrogenated phosphatidylserine(HPS). All agents were dissolved into the vehicle (1, 3-Butanediol, ethanol and water) at 0.5％ weight volume and applied on the dorsal area of the fuzzy rat. To observe histological changes, the skin biopsies were stained with Oil Red O and the size and morphology of sebaceous gland was observed under microscope. Topical treatment with PC and/or HPC showed a marked decrease in sebum excretion. Especially hydrogenated PC (HPC) appeared to have more predominant sebosuppressive function than any other treatment. The other agents such as PS and HPS showed a marginal effect on sebum secretion. With the sebosuppressive activity, HPC and PC seem to have a good potential application on acne treatment. In order to obtain more insights into possible mechanisms behind the above observations, effects of each phospholipid on the expression of peroxisome proliferator-activated receptor (PPAR) genes were investigated. Recently, it has been demonstrated that expression and activation of PPAR subtypes appear to modulate the accumulation of cytoplasmic fat droplets that characterizes the sebocyte differentiation(1). It was also previously suggested that PPAR${\gamma}$ antagonist would seem possible to interfere sebum production without side effects (2). In this study we examined the diverse effects of the tested phospholipids on the expression of several PPAR genes based on reverse transcription-polymerase chain reaction (RT-PCR) from the topically treated skin of fuzzy rats. The results and possible implications are discussed.

성호르몬은 lacrimal system, corneal anatomy and disease, aqueous humor dynamics and glaucoma, crystalline lens and cataract, retinal disease를 포함한 안과영역의 다양한 부위에 영향을 끼칠 수 있다. Androgen은 전신에 걸친 sebaceous glands의 발달, 분화, 지질생성 등에 관여하므로 androgen deficiency는 meibomian gland의 기능장애와 건성안에서 증발을 더욱더 심화시킬 수 있는 것으로 알려져 있다. 반면에 estrogens은 sebaceous glands의 크기, activity, 지질생성을 감소시켜 meibomian gland에서는 androgen과 반대되는 작용을 할 가능성이 있다. 성호르몬은 또한 각막의 구조와 질병경과에도 영향을 줄 수 있는데, 각막이 월경주기 제2일째 및 배란주위기에 두꺼워지며, 폐경 여성에서 여성호르몬 치료 시 각막두께가 증가한다는 사실은 estrogen levels과 각막 두께와의 연관을 시사하는 소견이라고 하겠다. Fuch's dystrophy 역시 폐경 후 여성에서 더 흔히 관찰되어, 나이에 따른 호르몬 변화가 그 원인 중 하나로 지목되고 있으며, vernal keratoconjunctivitis 환자의 각막조직에서는 estrogen과 progesterone 수용체의 overexpresson이 발견되어 역시 이들 질환에서의 성호르몬의 역할을 시사한다고 할 수 있겠다. 성호르몬은 안압에도 영향을 미칠 수 있는데, intraocular pressure와 혈중 luteinizing hormone, follicular stimulating hormone (FSH), estrone, estradiol, progesterone, testosterone과는 연관이 없는 것으로 보고한 결과도 있으나, 혈중 progesterone의 경우 특히 임신중인 여성에서 안압과의 연관관계가 보고되었으며, 또한 폐경 여성에서 혈중 남성호르몬 농도가 높을수록 안압이 상승하는 경향이 있음이 보고되었다. 한편 'Female sex'는 모든 종류의 백내장의 위험요소인 것으로 알려져 있다. 백내장으로 진단받은 여성의 경우 호르몬 측정 시 연령등을 보정하고도 폐경기에 가까운 호르몬 수치를 보였으며, 이들 백내장 환자군내에서는 estradiol과 FSH 농도 사이에 유의한 음의 상관관계가 보고되었다. 또한 DHEAS의 경우 백내장 위험도를 감소시키는 것으로 보고되었고, 그 기전으로 전구호르몬인 DHEA의 역할을 제시되고 있는데. 즉 백내장의 주요 기전 중 하나인 oxidative stress를 감소시키는 antioxidant activity를 DHEA가 보이기 때문일 것으로 추정되고 있다. 성호르몬은 망막 내 혈관의 흐름에도 영향을 줄 수 있는 것으로 알려져 있는데, 안구 내 혈류에서 여성호르몬의 긍정적인 효과와 남성호르몬의 부정적인 효과가 보고되었고, age-related macular degeneration (AMD)의 경우, estradiol이 ER-$\beta$ 수용체를 통해 보호효과가 있음이 보고되어, ER-$\beta$ 수용체가 향후 AMD 치료에서 치료적 target이 될 수도 있을 것으로 알려지고 있다. 또한 DHEAS의 경우 AMD 위험도를 증가시킬 가능성이 있으며, 당뇨로 진단받은 환자에서는 혈중 testosterone 농도는 당뇨병성 망막병증의 진행과 연관이 있는 것으로 보고되었다. 성호르몬은 안과영역의 다양한 질환과의 연관관계는 아직 추가연구가 필요한 실정이나 다양한 성호르몬이 안질환의 발생 및 경과에 영향을 줄 가능성이 있으며, 이와 같은 연관관계가 규명된다면 추후 호르몬을 통해 질환의 경과 및 예방의 가능성이 제시될 수도 있을 것으로 사료된다. 특히 폐경이후 다양한 안질환이 증가한다는 기존의 연구결과들을 고려 시, 안과영역에 있어 폐경기 여성호르몬 치료의 긍정적인 역할에 관해서는 지속적인 관심이 요구된다고 하겠다.

Purpose: Dermoid cysts are almost always caused by congenital events. The most widely accepted pathogenesis is that the cysts are dysembryogenetic lesions that arise from ectodermic elements entrapped during the midline fusion. We report a rare case of dermoid cyst, which occurred not congenitally but newly in the subcutaneous scar tissue secondary to trauma. Methods: A 26-year-old man had a deep submental laceration caused by a car accident and got a primary wound closure 16 months ago. There were 18 cm-long submental hypertrophic scar and newly developed palpable masses inside the subcutaneous layer at the center of the scar. Initial impression was an epidermal cyst or a thyroglossal duct cyst. Ultrasonographic finding showed two cystic masses inside the scars at the submental area, but impressed dermoid cysts. The cystic masses were completely removed with W-plasty and histological examination were followed. Results: The histological diagnosis was dermoid cysts which were mainly composed of keratotic squamous epithelium in their inner surface linings and numerous skin appendages such as sebaceous glands, sweat glands, and hair follicles in their cystic lumens histopathologically. During the follow-up period of 25 months, there was no recurrence of any subcutaneous mass in the site of scar. Conclusion: We report a very unusual case of dermoid cysts developed by an acquired cause, considering that the accidental inclusion of deep skin elements caused by a trauma can be a critical origin of dermoid cysts.

Objectives : The pores are the openings of sebaceous glands or apocrine glands. They are enlarged by various factors such as sex, age, genetic influence, sebum secretion, acne and so on. When the pores are visually recognizable, they become aesthetically problematic. There are various methods of treating pores, but we have tried to develop a method to reduce pore size by using daily cleanser. Methods : Facial skin examination was performed on 104 students of A university. Among them, 10 persons with large pore size were selected. We surveyed 72 students to determine their subjective skin condition, lifestyle, and washing habits etc. We made herbal fermented soaps using Seosiokyongsan and distributed them to experiment participants. We let them wash their face in the morning and evening for 6 weeks using herbal fermented soap. Prior to the experiment, their skin condition was checked and assessed using A-ONE Smart One-Click Automatic Facial Diagnosis System three times at 3-week intervals. After the experiment, the changes of skin were measured and analyzed through facial analysis test. Results : In our experiment, the early 20s, 9.6% of the students had slightly larger pores. For students with large pores, there was a high likelihood of side effects from using facial products. Using the fermented soap made of Seosiokyongsan, the average size of the pores and the number of large-sized pores were significantly reduced. Conclusion : Seosiokyongsan fermented soap can effectively reduce especially the large size of pores.

"Chimumchang" seems to be a kind eczema. The cause and symptom of eczema is similar to that of chimumchang. so, I investigated the literatures of oriental medicin and recent medicine. The results are summarized as follows. 1. Chimumchang seems to be a kind of eczema. Allergic contact dermatitis, atopic dermatitis, seborrheic dermatits, neurodermatitis, nummular dermatitis, xerotic eczema and so on are similar to chimumchang on cause & symptom. 2. The cause of chimumchang are summer vital energy excess(夏脈太過), sehwa excess(歲火太過), herat meridian wind-heat(心經風熱), heart fire(心火), wind taken spleen dampnees(脾濕受風), and so on. The cause of eczema are contact of external agent, immunological problem, heridity, infection, abnormalities of sebaceous glands, neurologic dysfuction, and so on. 3. The symptoms of chimumchang have been described to the three pattern on literature of oriental medicine until now. 1) scratching slightly, It has exudation, and combination. 2) Vital energy on skin is irritable by psychological problem. At the acute stage the patient is complain of itching & pain, and gradually the exudation expands in whole body. 3) early peorid it's size is very small, and at first the patient is complain of itching, later complain of pain. The exudation change to ulcer and expands in the whole body. 4. In the investigation of prescription(Total: 34, Oral medicine: 4, Ointment: 30), the most frequently used oral medicine is sungmatang(4 times), and the most frequently used ointment are kohosan, korvunsan and kegwanhyuldobang.
