Objective : Recent studies indicate that the deposition of beta-amyloid (Aβ) is related in the pathogenesis of Alzheimer`s disease (AD), but the underlying mechanism is still not clear. Method : To investigate the potential cellular functions of APP and LMK02, we use transgenic drosophila as a model was treated with either LMK02, and the effect in APP expression was determined by climbing assay. LMK02 have been shown to be neuroprotective in fly model systems. We asked whether dietary supplementation with LMK02 would influence behavior and AD-like pathology in a transgenic fly model. Result : LMK02 water extract have attenuated fly death in vivo. LMK02-treated fly increased percentage of flight ability more longly and survival ratio more than controls. APP-GRIM drosophila treated with LMK02 had significantly less accumulation of APP deposition in the eye and brain as compared to control drosophila. Conclusion : These results suggest that LMK02 prevent APP-induced neurotoxicity through attenuating flies death induced by APP, and may be useful as potential therapeutic agents for AD.

For standardization of LMK02 quality, Ginsenoside Rg3 of Red Ginseng and Decursin of Angelica gigas Nakai in the constituents of LMK02 were estimated as indicative components. From LMK02 water extract, has been used in vitro test for its beneficial effects on neuronal survival and neuroprotective functions, particularly in connection with APP-related dementias and Alzheimer's disease (AD). $A{\beta}$ oligomer derived from proteolytic processing of the ${\beta}$-amyloid precursor protein (APP), including the amyloid-${\beta}$ peptide ($A{\beta}$), play a critical role in the pathogenesis of Alzheimer's dementia. We determined that oligomer amyloid-${\beta}$ ($A{\beta}$) have a profound attenuation in the increase in rat hippocampus H19-7 cells from. Experimental evidence indicates that LMK02 protects against neuronal damage from cells, but its cellular and molecular mechanisms remain unknown. Using a hippocampus cell line on $A{\beta}$ oligomer-induced neuronal cytotoxicity, we demonstrated that LMK02 inhibits formation of $A{\beta}$ oligomer, which are the behavior, and possibly causative, feature of AD. In the Red Ginseng, the average amounts of Ginsenoside Rg3 were $47.04{\mu}g/g$ and $42.3{\mu}g/g$, 90 % of its weight were set as a standard value. And, in the Angelica gigas Nakai, the average amounts of Decursin were 2.71 mg/g and 2.44mg/g, 90 % of its weight were also set as a standard value. The attenuated $A{\beta}$ oligomer in the presence of LMK02 was observed in the conditioned medium of this $A{\beta}$ oligomer-induced cells under in vitro. In the cells, LMK02 significantly activated antiapoptosis and decreased the production of ROS. These results suggest that neuronal damage in AD might be due to two factors: a direct $A{\beta}$ oligomer toxicity and multiple cellular and molecular neuroprotective mechanisms, including attenuation of apoptosis and direct inhibition of $A{\beta}$ oligomer, underlie the neuroprotective effects of LMK02 treatment.

Objectives: This study was designed to investigate the effects of herbal composition and fermented Cervi Pantotrichum Cornu on the growth of longitudinal bone in the adolescent male rats. Methods: Longitudinal bone growth was measured by fluorescence microscopy. To examine the effects on the growth plate metabolism, the total height of growth plate and the induction of local insulin-like growth factor-1 (IGF-1) and bone morphogenetic protein-2 (BMP-2) were measured. Results: The herbal composition treatment enhanced longitudinal bone growth and total heght of growth plate and promoted the induction of local IGF-1 and BMP-2 of growth plate. Conclusions: This study showed that the herbal composition have the effect of bone growth in adolescent rats and might be used for the growth delayed adolescent and inherent growth failure patient.

Objective : Recent studies indicate that the deposition of β-amyloid (Aβ) is related in the pathogenesis of Alzheimer`s disease (AD), but the underlying mechanism is still not clear.Method : To investigate the potential cellular functions of APP and water extract of the JangwonHwangagambang (JWHG), we use as in vitro model, neuro 2A cells were treated with either JWHG or its oriental medicines, and the effect in APP expression was determined by MTT and LDH assay. JWHG have been shown to be neuroprotective in different model systems. We asked whether JWHG treatment would influence cell survival and AD-like pathology in APP-induced neuronal cells.Result : JWHG and water extracts of some oriental medicine has attenuated high cell death in vitro. JWHG-treated cells increased percentage of cell survival more longly than controls. JWHG had significantly increas neurite outgrowth in the as compared to control cells. Conclusion : These results suggest that JWHG prevent APP-induced neurotoxicity through attenuating oxidative stress, and may be useful as potential therapeutic agents for AD.
