The roots of Rumecis Radix have been used for the treatment of heat phlegm, jaundice, constipation, scabies and uterine hemorrhage. The aim of this study was to confirm whether Rumecis Radix water extract (RJWE) has a preventive effect on the development of atopic dermatitis (AD) in 2,4-dinitrochlorobenzene (DNCB)-applied BALB/c mice. Oral administration (12.5 mg/kg, 25 mg/kg) and topical application (0.5 mg/mouse, 1.0 mg/mouse) of RJWE decreased the development of AD-like skin lesions, ear swelling, spleen weight and total serum IgE. RJWE significantly also inhibited the infiltration of mast cells in the dorsal skin. Furthermore, the release of histamine from rat peritoneal mast cells (RPMCs) was suppressed significantly. These results suggest that the inhibitory effect of RJWE on AD might be associated with mast cells.

Objective : Cortex of Ulmi pumilae(CUP) has been used to treat several diseases including boil, swelling, and scabies etc. Recently, CUP was known to have wrinkle care and whitening actions. But, It's exact mechanisms are unclear. Methods : The present study was designed to investigate effects of CUP on Human HaCaT keratinocyte and malignant melanoma cells such as SK-MEL-2 and B16F10 in terms of cell viabilities, proliferations, DPPH free radical scavenging activities, oxygen free radical productions and inhibitory action on elastase activities. Results : CUP accelerated proliferation of HaCaT keratinocytes in the lower concentration. CUP also prevented cell death of HaCaT induced by Hydrogen peroxide, which products oxygen free radicals. On the contrary, CUP did not affect proliferations of SK-MEL-2 or B16F10. Futhermore, CUP showed inhibitory action against SK-MEL-2 proliferation at the concentration of $500{\mu}g/m{\ell}$ In addition, CUP was shown to have DPPH free radical scavenging activities and also have inhibitory effects on elastase activities too. On the fluorescent examinations, the present author knows that CUP elevated production levels of oxygen free radicals in malignant melanoma cell, SK-MEL-2. Conclusions : These results suggest that CUP has possibilities of usage for functional cosmetics which have wrinkle care and whitening activities and related mechanisms are involved in inhibition of elastase action and acceleration of oxidative stress in melanoma cell.

Synthetic pyrethroids are analysis of a natural chemical moiety, pyrethrin derived from the pyrethrum plant Chrysanthemum. The natural pyrethrin structure has been modified to be highly lipophilic and photostable, creating an effective pesticide and resulting in an increased presence in the environment. Worldwide, they are commonly used insecticides against ticks, mites, mosquitoes, and as treatment for human head lice and scabies. Therefore, human exposure to their compounds in extensive. Several studies on the effects of pyrethroids on thyroid hormone regulation, estrogen and androgen function have been reported and yet little has been done try assess their potential hormonal activities. Among humans, a pyrethroid compound was suggested to be the causal agent for gynecomastia in a group of Haitian men. The reports suggest that some pyrethroid compounds are capable of disrupting endocrine function. Therefore, we examined estrogenic/antiestrogenic potential of three pyrethroid insecticides, that is permethrin, allethrin and fenvalerate in human breast cancer cell and action mechanism mediated by the estrogen receptor. Fenvalerate showed weak estrogenic activity but aallethrin and permethrin showed no effect. In combination with high levels (10$^{-10}$ M, 10$^{-11}$ M) of 17$\beta$-estradiol and three synthetic pyrethroids inhibited cert proliferations in MCF7-BUS cell by 17$\beta$-estradiol. Whereas, fenvalerate increased cell proliferative activity at lower level of estradiol (10$^{-12}$ M, 10$^{-13}$ M). The relative affinities to the estrogen receptor were observed by allethrin and permethrin treatment, but not by fenvalerate. These results indicated that some of pyrethroid insecticides may modulate estrogen functions in human breast cancer cell. The action mechanisms of estrogen receptor mediated antiestrogenicity by allethrin and permethrin were postulated.

Rumex japonicus Houtt (RJH) is a valuable plant used in traditional medicine to treat several diseases, such as scabies and jaundice. In this study, Jurkat cell growth inhibitory extracts of R. japonicus roots were subjected to bioassay-guided fractionation, resulting in the isolation of three naphthalene derivatives (3-5) along with one anthraquinone (6) and two phenolic compounds (1 and 2). Among these compounds, 2-methoxystypandrone (5) exhibited potent anti-proliferative effects on Jurkat cells. Analysis by flow cytometry confirmed that 2-methoxystypandrone (5) could significantly reduce mitochondrial membrane potential and promote increased levels of mitochondrial reactive oxygen species (ROS), suggesting a strong mitochondrial depolarization effect. Real-time quantitative polymerase chain reaction (qPCR) analysis was also performed, and the results revealed that the accumulation of ROS was caused by reduced mRNA expression levels of heme oxygenase (HO-1), catalase (CAT), glutathione peroxidase (GPx), and superoxide dismutase (SOD). In addition, 2-methoxystypandrone (5) triggered strong apoptosis that was mediated by the arrest of the G0/G1 phase of the cell cycle. Furthermore, 2-methoxystypandrone (5) downregulated p-IκB-α, p-NF-κB p65, Bcl2, and Bcl-xl and upregulated BAX proteins. Taken together, these findings revealed that 2-methoxystypandrone (5) isolated from RJH could potentially serve as an early lead compound for leukemia treatment involving intracellular signaling by increasing mitochondrial ROS and exerting anti-proliferative effects.

After studing of viewpoint of surgical disease in seven medical books related with Ju Dan Gye(朱丹溪) among four eminent physicians in the Jin and Yuan dynasties(金元四大家) I get conclsion as following. 1. Studied surgical diseases are total 40 kinds. 2. In 40 kinds surgical diseaes, case of having theory are 20 kinds, cases of having no theory and having only treatement by medicine are 20 kinds. 3. In therapy, cases that mainly use a method to eliminate pathogenic factors are 27 kinds; Acute mastitis(乳癰), Deep-seated mammary abscess(내巖), Acute appendicitis(陽癰), Bone cellulitis(附骨疽), Carbuncle of the lower abdomen near external genitalia(便毒), Leprosy(癩風), Macule(斑), Rash(疹), Urticaria(은疹), Scrofula(나역), Stagnant plegm(結核), Goiter andtumer(영유), Erysipelas(丹), Furuncle(정瘡), Scabies(疥瘡), Chancre(下疳瘡), Syphilitic skin disease(樣梅瘡), Incised wound (金瘡), Dermatopathy of lower limb and heel(脚足部瘡), Pemphigus(天疱瘡), Itching eruption due to blood-heat or wind heat(血風瘡), Dermatopathy of head(頭面瘡), Scald and burn(湯火瘡), Tetanus(破傷風) , Ecthyma(염瘡), Fistula(久漏瘡), Tinea(癬瘡), Cases that mainly use external therapy are 5 kinds; Rhagades of hand and foot(手足군裂), Vulvar ulceration(婦人陰瘡), Chilblain(凍瘡), Rabies(풍狗咬), Tinea capitis(白禿瘡), Cases that mainly use a reinforcing method are 4 kinds; Internal deep-rooted carbuncle(內疽), Pruritus and dryness of skin(皮膚乾燥), Anul fistula(漏瘡), Macule Caused by disorder of internal organ(內傷發斑), Cases that mainly use eliminating first and then reinforcing are 2 kinds; Pyogenic infection and ulcerous disease of slin( 疽瘡상癰疽瘡瘍), Lung abscess(肺癰), Case that mainly uses reinforcement and elimination in combination is only Haemorroid(痔瘡). Case divided into two groups that are reinforcing method and a method to eliminate pathogenic factor is only Trauma(打撲). Case that have no treatment by medicine is only Abscess of the scrotum(囊癰). 4. In 40 kinds surgical diseases, we can know that except a few important surgical diseases, Ju Dan Gye haven't distinguished viewpoint in many surgical diseases, because there are many cases that have no theory and have only simple treatment of medicine, and that mainly use a method to eliminate pathogenic factors and external therapy. 5. Representative theory of Ju Dan Gye, nourishing Yin and extinguishing fire(滋陰降火), has little effect on therapy of surgical disease. We need to try statistical division of internal and external remedy in the future, and by studing of surgical disase in medical books related with four eminent physicians in the Jin and Yuan dynasties, I think we can see their viewpoint of surgical disease.
