Atopic dermatitis (AD) is a chronic and relapsing inflammatory disease that affects 1%-20% of people worldwide. Despite affecting many people, AD current treatments, such as corticosteroids and calcineurin inhibitors, have not only harmful secondary effects but are also often ineffective. Therefore, natural nontoxic compounds are on high demand for developing new effective AD treatments. Panax ginseng Meyer has been used traditionally for its promising healing and restorative properties to treat many diseases including skin disorders, reason why in this review we want to explore the research performed with AD and P. ginseng as well as determining its potential for new drug development. Previous researches have shown that P. ginseng has positive effects in AD patients such as lower eczema area and severity index, transepidermal water loss, and immunoglobulin E levels and better quality of sleep. In vivo animal models, as well, have shown positive results to P. ginseng and derived ginsenosides, such as the decrease of transepidermal water loss, immunoglobulin E levels in serum, allergy-related cytokines, and downregulation of NF-κB, MAPK, and Ikaros pathways. All of these previous data suggest that P. ginseng and its derived ginsenosides are undoubtedly a nontoxic effective option to treat AD.

Artemisia apiacea is a traditional herbal medicine using treatment of eczema and jaundice in Eastern Asia including China, Korea, and Japan. In this study, the three phytosterol constituents were isolated and identified from the hexane fraction of 80% aqueous methanol extract of A. apiacea. Compounds were isolated using open column chromatography (silica gel). Their chemical structures were also established using $^1H$-NMR and $^{13}C$-NMR. Moreover, neuroprotective activity of each compound against glutamate-induced neurotoxicity in hippocampal HT-22 cell line was evaluated by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. Furthermore, Inhibition of reactive oxygen species (ROS) and calcium ion ($Ca^{2+}$) accumulation were measured for elucidation of neuroprotective mechanism of isolated compounds. They showed that stigmasterol had neuroprotective activity against the glutamate-induced toxicity by inhibition of ROS and $Ca^{2+}$ production. In conclusion, isolated compound of A. apiacea might be useful for therapeutic agent against neurodegenerative diseases.

Lymphatic filariasis, transmitted by mosquitoes is the commonest cause of lymphedema in endemic countries. Among 120 million infected people in 83 countries, up to 16 million have lymphedema. Microfilariae ingested by mosquitoes grow into infective larvae. These larvae entering humans after infected mosquito bites grow in the lymphatics to adult worms that cause damage to lymphatics resulting in dilatation of lymph vessels. This earliest pathology is demonstrated in adults as well as in children, by ultrasonography, lymphoscintigraphy and histopathology studies. Once established, this damage was thought to be irreversible. This lymphatic damage predisposes to bacterial infection that causes recurrent acute attacks of dermato-lymphangio-adenitis in the affected limbs. Bacteria, mainly streptococci gain entry into the lymphatics through 'entry lesions' in skin, like interdigital fungal infections, injuries, eczema or similar causes that disrupt integrity of skin. Attacks of dermato-lymphangio-adenitis aggravates lymphatic damage causing lymphedema, which gets worse with repeated acute attacks. Elephantiasis is a late manifestation of lymphatic filariasis, which apart from limbs may involve genitalia or breasts. Lymphedema management includes use of antifilarial drugs in early stages, treatment and prevention of acute attacks through 'limb-hygiene', antibiotics and antifungals where indicated, and physical measures to reduce the swelling. In selected cases surgery is helpful.

Objectives : Mahaengeuigam-Tang (MHEGT) has been used as a traditional medicine for the treatment of rheumatic aerthritis, rheumatisim, eczema and asthma. The aim of this study was to investigate the molecular mechanisms of MHEGT for cartilage protection in monosodium iodoacetate(MIA)-induced osteoarthritis, particularly focusing on apoptosis. Method : Thirty young male Sprague-Dawley rats were used for the study. Rats were intra-articularly injected with 2 mg MIA in a total volume of 50 ㎕ saline. In MHEGT group, MHEGT extract was orally administered once daily to MIA-induced osteoarthritis rats, and rats of control group were given with saline only. At 4 weeks after MIA injection, all animals were sacrificed, and the histological changes and articular thickness were assessed by hematoxylin and eosin staining. Moreover, the immunohistochemical analyses of BAX and Bcl-2 were carried out. Results : The histomorphological examinations revealed that MHEGT reduced MIA-induced cartilage damage. And, MHEGT ameliorated the severity of cartilage surface damages after MIA injection. Furthermore, MHEGT suppressed the MIA-induced increases of pro-apoptotic BAX protein and increased the protein expression of anti-apoptotic Bcl-2 protein. Conclusion : These findings indicate that MHEGT protects against MIA-induced cartilage damage by inhibition of the apoptotic pathway, demonstrating significant protection of cartilage against osteoarthritis. These results suggest that MHEGT may potentially have clinical applications in the treatment of osteoarthritis.

Cudrania tricuspidata (C. tricuspidata) is a deciduous tree found in Japan, China and Korea. The root, stems, bark and fruit of C. tricuspidata has been used as traditional herbal remedies such as eczema, mumps, acute arthritis and tuberculosis. In this study, we investigated the potential efficacies of this natural compound by focusing on the inhibitory effect of cudraxanthone L (CXL) isolated from the roots of C. tricuspidata on human platelet aggregation. Our study focused on the action of CXL on collagen-stimulated human platelet aggregation, inhibition of platelet signaling molecules such as fibrinogen binding, intracellular calcium mobilization, fibronectin adhesion, dense granule secretion, and thromboxane A2 secretion. In addition, we investigated the inhibitory effect of CXL on thrombin-induced clot retraction. Our results showed that CXL inhibited collagen-induced human platelet aggregation, intracellular calcium mobilization, fibrinogen binding, fibronectin adhesion and clot retraction without cytotoxicity. Therefore, we confirmed that CXL has inhibitory effects on human platelet activities and has potential value as a natural substance for preventing thrombosis.
