Bio-Green(B.G.) functional water was manufactured by Kyungwon Enterprise Co. through a series of processes ; water longrightarrow ultra-purification longrightarrow adding catalysts longrightarrow energy imprinting fermenting with energized water + zeolite and others + photosynthetic bacteria in fermenter longrightarrow filtering. Control(0), 5 or 10 liters of B.G. functional water were supplied to the orchard soil under canopy of 10 year old 'Tsugaru'/M26 apple trees on March 20, May 20 and June 20, 1995, respectively. Some orchard soil characteristics, not only pH, but also Ca and Mg of exchangeable cations were increased by supply with B.G. functional water. However, P$_2$O$_{5}$, K, and B contents were not influenced by the treatment. At harvest time soluble solid content of flesh and anthocyanin of fruit skin were increased by the treatment. B.G. functional water treatment showed higher root activities, and photosynthesis of leaves than that of control. Also B.G. functional water treatment showed higher Ca content in fruit skin and flesh tissues, whereas not affected N, K, and Mg contents. During storage at 4$^{\circ}C$ cold room, the more volume of B.G. functional water supply showed lower bitter pit symptom. Respiration and ethylene evolution in fruit were decreased, while fruit firmness increased by the treatment during storage.e.

Itching is a common clinical symptom of skin disease that significantly affects a patient's quality of life. Transient receptor potential vanilloid 1 (TRPV1) receptors of keratinocytes and peripheral nerve fibers in skin are involved in the regulation of itching as well as pain. In this study, we investigated whether curcumin, which acts on TRPV1 receptors, affects histamine-induced itching in mice, using behavioral tests and electrophysiological approaches. We found that histamine-induced itching was blocked by topical application of curcumin in a concentration-dependent manner. In ex-vivo recordings, histamine-induced discharges of peripheral nerves were reduced by the application of curcumin, indicating that curcumin acts directly on peripheral nerves. Additionally, curcumin blocked the histamine-induced inward current via activation of TRPV1 (curcumin $IC_{50}=523nM$). However, it did not alter chloroquine-induced itching behavior in mice, which is associated with transient receptor potential ankyrin 1 (TRPA1). Taken together, our results suggest that histamine-induced itching can be blocked by topical application of curcumin through the inhibitory action of curcumin on TRPV1 receptors in peripheral nerves.

Although pruritus is the critical symptom of atopic dermatitis that profoundly affect the patients' quality of life, controlling and management of prurirtus still remains as unmet needs mainly due to the distinctive multifactorial pathogenesis of pruritus in atopic dermatitis. Based on the distinct feature of atopic dermatitis that psychological state of patients substantially influence on the intensity of pruritus, various psychotropic drugs have been used in clinic to relieve pruritus of atopic dermatitis patients. Only several psychotropic drugs were reported to show real antipruritic effects in atopic dermatitis patients including naltrexone, doxepin, trimipramine, bupropion, tandospirone, paroxetine and fluvoxamine. However, the precise mechanisms of antipruritic effect of these psychotropic drugs are still unclear. In human skin, serotonin receptors and serotonin transporter protein are expressed on skin cells such as keratinocytes, melanocytes, dermal fibroblasts, mast cells, T cells, natural killer cells, langerhans cells, and sensory nerve endings. It is noteworthy that serotonergic drugs, as well as serotonin itself, showed immune-modulating effect. Fenfluramine, fluoxetine and 2, 5-dimethoxy-4-iodoamphetamine significantly decreased lymphocyte proliferation. It is still questionable whether these serotonergic drugs exert the immunosuppressive effects via serotonin receptor or serotonin transporter. All these clinical and experimental reports suggest the possibility that antipruritic effects of selective serotonin reuptake inhibitors in atopic dermatitis patients might be at least partly due to their suppressive effect on T cells. Further studies should be conducted to elucidate the precise mechanism of neuroimmunological interaction in pruritus of atopic dermatitis.

This paper is a study to find the philological basis of Bihoon (鼻熏) therapy. There is no separate philological study of Bihoon therapy to date, and for this reason, there is no clear definition or specific treatment manual. In this study, a related database was created and analyzed by examining literature data related to Bihoon therapy, focusing on Korean traditional medical books. There were about 1,000 data points related to Bihoon therapy in 45 kinds of medical books. They were largely classified into 1. Acute diseases such as insensitivity, 2. Diseases that occur in the upper human body such as nose, head, eyes, and throat, 3. Women's diseases related to childbirth, 4. Treatment of skin diseases and prevention of infectious diseases. In the case of insensitivity treatment, the focus was on awakening the patient's mind, and the treatment of diseases such as the nose, head, eyes, etc. was focused on resolving each symptom. Symptoms related to childbirth were mainly treated for uterine escapism or fainting after childbirth, while skin diseases were mainly treated for diseases that did not heal well, such as amniotic fluid. If a multifaceted approach to non-discipline therapy is added in the future, it is expected that clinical utilization will also be increased.

Purpose : To investigate the effects of the lavender, lemon and eucalyptus oil mixture on the atopy dermatitis skin lesions induced on NC/Nga Mice by dinitrochlorobenzene (DNCB). Material and Method : For this purpose, we fabricated the oil mixture blending three essential oils (lavender, lemon, eucalyptus : ELL) with one carrier oil (jojoba) and apply it on the atopic dermatitis skin lesions of NC/Nga Mice. Atopic dermatitis in NC/Nga Mice was induced by DNCB treatment on the dorsal skin of mice for 8 weeks. The mixture of ratio of each essential oil drop was 1 (eucalyptus) : 2 (lemon) : 2 (lavender) and this mixture was blended with jojoba oil 50ml (0.025%). The ELL-ointment was supplied for 8 weeks. We evaluated the effects of ELL on cell viability of mouse lung fibroblast, clinical skin features and severity, the level of serum Immunoglobulin (Ig) E & Ig G1, Interleukin (IL)-4, IL-13 and Interferon (IFN)-$\gamma$. Results : ELL showed safety on the cell viability of mouse lung fibroblast compared with control group. The cell viability was measured by SRB method. The effects of ELL on clinical skin features and severity in DNCB-induced dermatitis model of NC/Nga mice was significant compared with control group. EEL also showed significant effects on clinical symptom score compared with control group. Serum IgE & IgG1 level and development of atopy dermatitis skin lesions were evaluated. Serum IgE & IgG1 production was significantly down-regulated in EEL group compared with control group. ELL also down-regulated the levels of IL-4 and IL-13, and up-regulated the level of IFN-$\gamma$ compared with control group significantly. Conclusion : ELL was effective on atopy dermatitis by modulating Th2 related factors.

Objectives : Adenophorae Radix(AR) is the dried root of Adenphora triphylla var. japonica HARA. AR has the efficacy of clarifying lung, emitting pus, expelling wind, stopping pruitus and so on. Recently, various studies are being done about anti-oxidative, immunomodulatory and anti-inflammatory effects of AR. So, we expected AR has an availability that can improve symptoms of atopic dermatitis(AD). Methods : In this study, we measured body weight, weight of ear, thickness of ear skin and dorsum skin, symptom score, reproduction rate of splenocytes in vivo and in vitro of mouse with AD induced by DNCB. We experimented with five groups of 9 mice, such as normal group, control group, AR spread(ARS) group, AR feeding(ARF) group, AR spread&feeding(ARSF) group. Results : Control group of body weight significantly reduced and APSF group significantly increased in the first and second week. In weight of ear and thickness of ear skin and dorsum skin, control group significantly increased and ARSF group significantly decreased. In macrophotography viewpoint of dorsal skin, ARS group, ARF group and ARSF group decreased severe pigmented skin lesion, erythema and desquamation as compared with control group. Especially ARSF group showed significant drop. ARS group, ARF group and ARSF group compared to control group were improved in histopathology observation. In vitro and in vivo, treatment group of AR increased proliferation rate of splenocytes, specially in vitro significantly. Conclusions : This experiment indicates Adenophorae Radix extracts is effective on AD induced by DNCB in mice.

Since facial skin pigmentation is one of the visual characteristics of skin aging, it is important to evaluate skin pigmentation in the cosmetics and aesthetic fields. Several groups have investigated and developed the image analysis methods for skin pigmentation and some of the groups reported the age-related changes of the number and size of facial pigmented spots. However, they didn't show the changes of the number and size of pigment spots by defined size, and there is no report for Korean female regarding pigmentation. A total of 194 Korean females aged 20 ~ 79 (48.97 ± 17.11 years) were analyzed for the number, size, and intensity of pigmented spots using various filters such as large high-pass filter and median filter in their digital facial images. There were significant correlations between age and total pigmented spot number (No.), size, and intensity (I) (pearson's correlation coefficient r = 0.688, r = 0.645, r = -0.563), and significant correlations were also observed between the number and intensity of pigmented spots of different sizes. According to the ANOVA results, there were significant differences in the percentage of spot size of 2 ~ 4 mm² and > 20 mm² between 20's and 70's. In other words, with aging, pigmentation increases in the facial skin, and the large increase in pigmentation is particularly noticeable in Korean women.

The purpose of this study was to examine the effects of Lespedeza Caneata (LC) extracts on atopic dermatitis. For the experiment, mice were divided into a normal group, an AD group, and AD-LC groups (100 mg/Kg, 300 mg/Kg, and 500 mg/Kg). For the AD and AD-LC groups, 1% DNCB $200{\mu}{\ell}$ was applied at a hair-removed site for 2 weeks, and then 0.1% DNCB $150{\mu}{\ell}$ was applied every 2 days for 4 weeks. Skin thickness is a symptom of atopic dermatitis, and in this experiment, the AD group had the thickest skins, and the AD-LC group (500 mg/Kg) had the same skin thickness as the normal group. Mast cells show inflammatory reaction, and in this experiment, the AD group had the largest number of mast cells. Collagen fibers are usually observed on normal skins, and in this experiment, the AD-LC group (500 mg/Kg) had a uniform level of those fibers. Based on the study results, it turned out that LC extracts have the anti-atopic efficacy improving keratinization, erosion, and uredo.

Objective : Low level laser therapy(LLLT) is conjugated many different diseases such as skin disease, nervous system disease, cardiovascular disease, etc. This study was tried to survey the conjugation of LLLT in field of ophthalmology, otolaryngology and dermatology of Korean Medicine. Methods : In this study, LLLT deal with the field of ophthalmology, otolaryngology and dermatology was searched at Pubmed and NDSL. We searched Pubmed and NDSL with the title "Laser Therapy and Low-Level" for the last 10 years and analyzed disease, laser type, sample size, effect, journal and year. Results : Using Pubmed and NDSL, 8 treatises were researched. About 8 treatises, 7 treatises were papers in field of dermatology, 1 treatise was ophthalmology. And about 8 treatises, 6 treatises were foreign papers and 2 treatises were domestic papers on clinical application of laser status. Mainly used type of laser was a He-Ne laser and Diode laser. The diseases were ocular hypertension, acne, ulcers in patients with leprosy sequelae, freckles, segmental-type vitiligo lesions, diabetes-linked skin lesion, facial skin melanin and elasticity, atopic dermatitis symptom. As a result, we found that treat group had more improvement than control group in 7 of the 8 treatises, that treat group had no difference control group on effect significantly only 1 treatise. Conclusions: As therapeutic tool, LLLT's application range is very wide in the field of ophthalmology, otorhinolaryngology, and dermatology. Keep up with the increasing interest of domestic and foreign about laser therapy, clinical tries on the use of laser will be studied steadily. It is necessary to have sustained attention and research on the point of view of the Korean Medicine.
