BackgroundMineral water from deep-sea bedrock, formed over thousands of years, is rich in minerals such as Ca, Mg, Na, K, Fe and others. Our present study was to investigate the preventive effects of natural deep-sea water on developing atopic dermatitis (AD).MethodsWe elicited AD by application of DNCB (2,4-dinitro-chlorobezene) in Nc/Nga mouse dorsal skin. Deep Sea water (DSW) was filtered and concentrated by a nanofiltration process and reverse osmosis. We applied concentrated DSW (CDSW) to lesions five times per week for six weeks, followed by evaluation. 1% pimecrolimus ointment was used as positive control. The severity of skin lesions was assessed macroscopically and histologically. Levels of inflammatory mediators and cytokines in the serum were detected by Enzyme-linked immunosorbent assay (ELISA) and the levels of CD4+ and CD8+ spleen lymphocytes were determined by flow cytometry analysis.ResultsDNCB-treated mice showed atopic dermatitis-like skin lesions. Treatment of mice with CDSW reduced the severity of symptoms in the skin lesions, including edema, erythema, dryness, itching, and transepidermal water loss (TEWL). Histological analyses demonstrated that epidermal thickness and infiltration of inflammatory cells were decreased after CDSW treatment. Given these interesting observations, we further evaluated the effect of CDSW on immune responses in this AD model. Treatment AD mice with CDSW inhibited up-regulation of IgE, histamine, and pro-inflammatory cytokines in the serum. Also, the CD4+/CD8+ ratio in spleen lymphocyte was down-regulated after treatment with CDSW. Finally, cytokines, especially IL-4 and IL-10 which are important for Th2 cell development, were reduced.ConclusionsOur data suggests that topical application of CDSW could be useful in preventing the development of atopic dermatitis.
Interleukin-12, a heterodimeric cytokine comprising p40 and p35 subunits, plays an essential role in the regulating the differentiation of Th cells, which establish and maximize the capabilities of the immune system. The aim of present study is to screen the effect of 21 ginsenosides from steamed ginseng-leaves and flowers on IL-12 production in bone marrow-derived dendritic cells induced by lipopolysaccharide. Noticeably, ginsenoside Rg(6) (12) and ginsenoside F(4) (13) exhibited particularly inhibitory effect on LPS-induced IL-12 production with the inhibition values of 80 and 82%; and ginsenoside ST(1) (4), ginsenoside SL(2) (8), ginsenoside SL(3) (9), ginsenoside Rh(3) (14), ginsenoside Rk(2) (15), and ginsenoside Rs(4) (18) showed moderate effects with inhibition rates of 63, 65, 67, 68, 71, 73, and 67%, respectively. These results warrant further studies concerning potential of saponin extracts of steamed ginseng-leaves and flowers for medicinal uses.
[Purpose] The present study aimed to determine the effect of an 8-week program of joint
mobilization on changes in pelvic obliquity and pain level in seventeen female university
students aged in their 20’s with sacroiliac joint dysfunction by dividing them into two
groups: a joint mobilization group (MWM) and a control group. [Subjects] Seventeen
subjects were selected from female university students aged in their 20’s attending N
University in Cheon-An City, Korea, The subjects had sacroiliac joint syndrome, but
experienced no problems with daily living and had no previous experience of joint
mobilization exercise. The subjects were randomly assigned to a joint mobilization group
of eight and a control group of nine who performed joint mobilization exercise. [Methods]
Body fat and lean body mass were measured using InBody 7.0 (Biospace, Korea). The Direct
Segmental Multi-frequency Bioelectrical Impedance Analysis Method (DSM-BIA) was used for
body composition measurement. A pressure footstool (Pedoscan, DIERS, Germany) and a trunk
measurement system (Formetric 4D, DIERS, Germany), a 3D image processing apparatus with
high resolution for vertebrae, were used to measure 3D trunk images of the vertebrae and
pelvis obliquity, as well as static balance ability. [Result] The MWM group showed a
significantly better Balance than the control group. In addition, the results of the
left/right and the front/rear balance abilities were significantly better than those of
the control group. [Conclusion] This study proved that a combination of mobilization with
movement and functional training was effective in reducing pelvis malposition and pain,
and improving static stability control.
