Objective : This research aims to investigates the effects of CMT and HCMT on Dementia. and we also want to know the different effect of CMT, HCMT by drug types. Methods : The research is progressed by two types of experiment. one experiment is BV2 microglial cell line treated by LPS in vitro and another experiment is memory deficit mice induced by scopolamine in vivo. Results : The CMT and HCMT is effective in BV2 microglial cell line treated by LPS in vitro and in the serum of the memory deficit mice induced by scopolamine in vivo. But, there is no significant difference between CMT and HCMT extract&nano powder in experimental conclusion. Conclusions : These results suggest that the two drug types of CMT and HCMT may be effective for the prevention and treatment of Dementia. Investigation into the further study two drug types of the CMT and HCMT for Dementia is suggested for future research.

Background: Chong-Myung-Tang (CMT) extract is widely used in Korea as a traditional herbal tonic for increasing memory capacity in high-school students and also for numerous body ailments since centuries. The use of CMT to improve the learning capacity has been attributed to various plant constituents, especially black ginseng, in it. Therefore, in this study, we have first investigated whether black ginseng-enriched CMT extracts affected spatial learning using the Morris water maze (MWM) test. Their molecular mechanism of action underlying improvement of learning and memory was examined in vitro. Methods: We used two types of black ginseng-enriched CMT extracts, designated as CM-1 and CM-2, and evaluated their efficacy in the MWM test for spatial learning behavior and their anti-inflammatory effects in BV2 microglial cells. Results: Our results show that both black ginseng-enriched CMT extracts improved the learning behavior in scopolamine-induced impairment in the water maze test. Moreover, these extracts also inhibited nitric oxide production in BV2 cells, with significant suppression of expression of proinflammatory cytokines, especially inducible nitric oxide synthase, cyclooxygenase-2, and $interleukin-1{\beta}$. The protein expression of mitogen-activated protein kinase and nuclear $factor-{\kappa}B$ pathway factors was also diminished by black ginseng-enriched CMT extracts, indicating that it not only improves the memory impairment, but also acts a potent anti-inflammatory agent for neuroinflammatory diseases. Conclusion: Our research for the first time provides the scientific evidence that consumption of black ginseng-enriched CMT extract as a brain tonic improves memory impairment. Thus, our study results can be taken as a reference for future neurobehavioral studies.

Objectives: This study examined the effects of 8 types of herbal prescriptions prescribed to alleviate dementia symptoms in a rat model of arterial thrombosis induced by ferric chloride ($FeCl_3$). Methods: Thirty minutes before 35% $FeCl_3$ treatment, SD rats were intraperitoneally injected with the 8 types of herbal prescriptions, respectively. We tested the effects of the herbal prescriptions on time to occlusion (TTO) in an arterial thrombosis model using a laser Doppler flow meter. In addition, thrombus weight (TW) and collagen fiber damages were evaluated in the same condition. Results: Herbal prescriptions showed the following rank-order based on their TTO: Chong-myung-tang (CMT) > modified Jangwonhan 02 (LMK02) > Toki-shakuyaku-san (TSS) ${\geq}$ Oren-gedoku-to (OGT) ${\geq}$ Yokukansan (YKS). In particular, CMT (100 mg/kg, i.p.) and LMK02 (100 mg/kg, i.p.) delayed the TTO the most ($14.83{\pm}0.98$ and $13.67{\pm}1.03$ min, respectively) compared with the vehicle group ($7.95{\pm}0.78$ min, P<0.001). In addition, CMT, LMK02, and OGT treatment ($0.63{\pm}0.01$, $0.66{\pm}0.02$ and $0.67{\pm}0.01$ mg/mm, respectively) significantly reduced thrombus weight compared with the vehicle treatment ($0.78{\pm}0.03$, P<0.001) and also alleviated collagen fiber damage (CMT; $28.40{\pm}2.22$%, LMK02; $30.79 {\pm} 4.07$%, OGT; $26.20{\pm}1.48$%) in the vessels injured by $FeCl_3$. Therefore, CMT and LMK02 showed the greatest preventive activity in rat model of arterial thrombosis induced by $FeCl_3$. Conclusions: These results provide experimental evidence for traditional use of herbal prescriptions, suggesting that CMT and LMK02 extracts could be used to prevent vascular injury and thrombosis in the early stages of dementia.
