Objectives: Maekmoondong-tang and Jeongcheonhwadamgangki-tang are herbal decoctions which have been used as traditional therapeutic agents for asthma. This study was performed to investigate the effects of Maekmoondong-tang and Jeongcheonhwadamgangki-tang on immune Cell & serum OA-specific 19B in broncho-alveolar lavage fluid (BALF) in rat asthma model. Methods: Rats were sensitized with ovalbumin (OA); at day I the sensitized group and Maekmoondong-tang and Jeongcheonhwadamgangki-tang groups were systemically immunized by subcutaneous injection of 1mg OA and 300mg of $Al(OH)_3$ in a total volume of 2ml. At the same time, 1ml of 0.9% saline containing $6{\times}10^9$ B. pertussis bacilli was injected by i.p. for 14 days. After systemic immunization, the rats received local immunization by inhaling 0.9% saline aerosol containing 2% (wt/vol) OA. A day after local immunization, BAL fluid was collected from the rats. A day after local immunization, rats were orally administered with each of Maekmoondong-tang and Jeongcheonhwadamgangki-tang extract for 14 days. Lymphocyte, CD4+T-cell CD8+ T-cell counts, CD4+/CD8+ ratio in BALF, change of serum OA-specific IgE level, and CD4+T-cell CD8+T-cell percentage in the peripheral blood were measured and evaluated. Results: Maekmoondong-tang and Jeongcheonhwadamgangki-tang showed a suppressive effect on the rat asthma model. Maekmoondong-tang decreased total cell, lymphocyte, CD4+T-cell, CD8+T-cell in BALF, and serum OA specific 19B level as compared with the control group, whereas Maekmoondong-tang decreased CD4+/CD8+ ratio in BALF with statistical nonsignificance as compared with the control group. 1 decreased total cell, CD4+T-cell, CD4+/CD8+ ratio in BALF, and serum OA specific IgE level, whereas Jeongcheonhwadamgangki-tang decreased ymphocyte, and CD8+T-cell in BALF with statistical nonsignificance as compared with the control group. CD4+T-cell and CD8+ T-cell percentage in peripheral blood were not changed significantly in all the experimental groups. Conclusions: This study shows that Maekmoondong-tang and Jeongcheonhwadamgangki-tang have a suppressive effect on asthma. Maekmooruiong-tang and Jeongcheonhwadamgangki-tang would be useful asthma treatment agents.

This study was conducted to develop a healthy and functional drink using red ginseng, maekmoondong and omija using Saengmaeksan. Since the red ginseng extract was used as a raw material, it was diluted from 1,000 to 1,500 times using distilled water and the highest sensory score was obtained when the red ginseng extract was diluted to 1,500 times. When the red ginseng extract was mired with omija and maekmoondong, there was no difference between the ratio of 1: 20 : 1, 1 : 21 : 1 and 1: 22: 1 (red ginseng : omija : maekmoondong). In case of sweetener, honey showed the highest sensory store compared to sucrose, pear extract apple extract, sucralose and aspartame. Additionally, the sweetness was evaluated using all sweeteners and 10 brix or 11 brix showed the highest sensory score. Therefore, red ginseng extract was first mixed with omija and maekmoondong in the ratio of 1 : 20 : 1, and distilled water was added to 1,500 times of the amount of red ginseng extract. Honey was finally added to the mixture to obtain 10 brix concentration and this was highly acceptable.

The purpose of this research was to investigate the effect of Maekmoondong-tang(MMDT) on the activity of immune cell. The addition of MMDT(10 ㎍/㎖) enhanced the proliferation of cultured-splenocytes and thymocytes. And administration of MMDT(250, 500 ㎎/㎏) accelerated subpopulation of splenic T lymphocytes in BALB/c mice. In contrast, the treatment of the high concentration (500 ㎎/㎏)of MMDT were decreased thymic T lymphocytes. Administration of MMDT(250, 500 ㎎/㎏) eminently enhanced the production of IFN-γ. And MMDT did not affect the cell viability of Jurkat leukemia cells. These results suggest that MMDT have a immunoregulatory effect via enhanced cell mediated immunity

In this study, we verified the 1-1-diphenyl-2-picryl-hydrazyl radical scavenge, 2,2'-azinobis(3-ethylbenzothiazoline-6-sulfonic acid) radical scavenge, elastase, tyrosinase inhibitory effect by using the solvent fractions of Maekmoondong-tang hot water extract. As a result, the ethyl acetate fraction (MW-EA) showed the highest inhibitory activity. In cell-based assays, MW-EA treatment confirmed a 34% ($100{\mu}g/mL$) efficacy in reactive oxygen species inhibitory activity, and at the same concentration, MMPs showed more than 50% inhibition and tyrosinase inhibited 25% ($50{\mu}g/mL$). Therefore Maekmoondong-tang is considered high development potential as a material to improve the skin.

Objectives : Maekmoondong-tang (MMDT), a Korean herbal medicine, has been used to treat severe dry cough in patients with bronchitis and pharyngitis. MMDT has been reported to have anti-inflammatory, anti-allergic, immunomodulatory, secretory-modulating, and metabolic regulatory actions. However, there are no evidence in regard to the effects of MMDT on carcinogenesis and metastasis. Here, we investigated the effects of 70% ethanol extract of MMDT on cell viability, apoptosis, and motility in human hepatocarcinoma HepG2 cells. Methods : Cell viability was measured using the CCK-8 assay, and the apoptosis induction was evaluated by caspase-3 activity. To detect apoptotic features, the cells treated with MMDT were stained with 4'-6-diamidino-2-phenylindole (DAPI). Cell motility was examined by Boyden chamber assay and Real-time Cell Index of Migration assay. Gelatin zymography also performed to measure matrix metalloproteinase (MMP)-2/9 activity. Results : We found that MMDT significantly inhibited cell proliferation and increased caspase-3 activity in a dose-dependent manner in HepG2 cells. Apoptotic features such as chromatin condensation and apoptotic bodies were observed in MMDT-treated cells by DAPI staining. MMDT also suppressed PMA-induced cell motility and activities of MMP-2/9. Conclusions : Our results exhibited that MMDT possess the anti-carcinogenetic and anti-metastatic activities via caspase-3 activation and down-regulation of cell motility and invasion in HepG2 cells. Therefore, these findings suggest that MMDT could be potentially applied to the prevention and treatment of cancer.

Objective: This study investigated the effect of Yin deficiency medicine on halitosis patients and the relationship between subjective recognition and objective symptoms of oral malodor. Methods: We administered Yin deficiency medicine, such as Jaeumganghwa-tang, and conducted the Halitosis Associated Life-quality Test (HALT) and $OralChroma^{TM}$. Subjective recognition of halitosis was evaluated using HALT. Objective symptoms of halitosis were evaluated using $OralChroma^{TM}$. In addition, before and after administering medicine, we determined the halitosis according to percentages at the patient's word. Results: The total gas and HALT were not related to each other after Maekmoondong-tang or Saengmaek-san were administered to 10 halitosis patients. Conclusion: Yin deficiency medicine is effective in treating halitosis. Moreover, the subjective recognition and objective symptoms of halitosis are not related to each other.

Experiment for analysing changes of growth, tuber yield and total sugar content during wintering was performed with Maekmoondong 1(L. platyphylla WANG et TANG). The growth of over ground characteristics including leaf length, tiller number and fresh leaf weight lasted to the middle of April. The growth and filling of tuber were progressed and got to the top of tuber yield (387kg/l0a) in the middle of March, showing the optimum harvesting time in Big Blue Lilyturf cultivation. Total sugar content showed the highest value(79%) in the late of January and was decreased gradually to the middle of March during wintering. There was highly significant negative correlation between total sugar content and tuber yield.
