Objectives : The aim of this research was to determine the diverse effects of Lithospermi Radix Water Extract (LR) on human keratinocyte HaCaT cells, and to examine whether those effects could be applied to the human skin. Methods : We examined effect of LR on the cell viability of using the MTS assay in human keratinocyte HaCaT cells. The antioxidation effect of LR was analyzed relative to the well-known antioxidant resveratrol, using an ABTS assay. Quantitative RT-PCR analysis revealed that, in HaCaT cells, LR influenced the mRNA expression of tight-junction genes associated with skin moisturization. Furthermore, a wound-healing assay demonstrated altered cell migration in LR-treated HaCaT cells. Result : The cytotoxicity was confirmed to be higher in LR at a concentration of $800{\mu}g/m{\ell}$ using the MTS assay in HaCaT cells. In comparison to $100{\mu}M$ resveratrol, $1,600{\mu}g/m{\ell}$ LR showed either a similar or superior antioxidation effect. LR treatment in HaCaT cells reduced the mRNA expression levels of claudin 3, claudin 4, claudin 6, claudin 8, and ZO-2 to less than 0.80-fold, whereas JAM-A and Tricellulin mRNA expression level increased more than 1.33-fold. In addition, HaCaT cells migration was decreased to 83.9% by LR treatment. Conclusions : LR of antioxidation activity will have an anti-aging effect on the skin by reducing oxidative stress. Further studies are required to address the implications for human skin, given LR's effects of altering mRNA expression of tight junction-related gene and decreasing cell migration of HaCaT cells.

Objectives : This study was performed to investigate the effects of $LR_3$ and $SP_6$ acupuncture on renal damage in streptozotocin(STZ)-induced diabetic mice. Methods : ICR male mice were stabilized for a week and divided into four groups: a normal mice group(N), no-acupuncture diabetic mice group(Control), $LR_3$ acupuncture diabetic mice group($LR_3$), and $SP_6$ acupuncture diabetic mice group($SP_6$). Diabetes was experimentally induced by intraperitoneal injection of STZ(150 mg/kg) in citrate buffer(pH 4.5). For two weeks, $LR_3$ and $SP_6$ acupunctures were administered bilaterally at each point once a day. After two weeks, the animals' weight was measured and they underwent a laparotomy. Serum glucose and blood urea nitrogen(BUN) were measured from the blood taken from the heart. We measured glucose, reactive oxygen species(ROS), peroxynitrite($ONOO^-$) and thiobarbituric acid reactive substances(TBARS) in the kidney and compared expression levels of superoxide dismutases(SOD), glutathione peroxidase(GPx), nuclear factor-kappa B(NF-${\kappa}B$), cyclooxygenase-2 (COX-2), inducible nitric oxide synthase(iNOS) and Interleukin-1 beta(IL-$1{\beta}$). Results : BUN significantly decreased in $LR_3$, $SP_6$ compared to the control group. $LR_3$ showed significantly decreased glucose compared to the control group. $LR_3$, $SP_6$ significantly decreased in ROS and $ONOO^-$ compared to the control group. $LR_3$ significantly decreased in TBARS compared to the control group. $SP_6$ significantly increased in expressions of SOD-1, catalase, and GPx compared to the control group. $LR_3$, $SP_6$ significantly decreased in COX-2 compared to the control group. $SP_6$ significantly decreased in IL-$1{\beta}$ compared to the control group. Conclusions : This study suggests that $LR_3$ acupuncture may be effective in controlling glucose and lipid peroxidation and that $SP_6$ acupuncture may have anti-oxidative and anti-inflammatory effects on renal damage in STZ-induced diabetic mice.

Objective: Purpose of this study was to examine the effect of electroacupuncture(EA) at Xingjian(LR2) as 'Fire(火)' point of The Leg Absolute Um Liver Meridan(足厥陰肝經 : Chok-Kworum-Kan-Kyong) on the facial thermal change. Methods: Subjects of this study were 15 patients with upperpart(includes head and facial part) fever of human body and two examinations were carried out in each other day. We divided cases of two examinations into two groups. One is experimental group(N=15) that was carried out electroacupuncture stimulation at Xingjian(LR2), the other is control group(N=15) which was carried out electroacupuncture stimulation at optional point(in space between 1st and 2nd fingers) except acupuncture points of 12 meridians. We took the temperature of fixed areas on face by digital infrared thermal image(D.I.T.I.) before and after electroacupuncture stimulation. Those fixed areas on face that was taken temperature are Jingming(BL1), Sibai(ST2), Dicang(ST4), Indang, Shuigou(GV26), Chengjiang(CV24) areas. In cases of temperature of Jingming(BL1), Sibai(ST2), Dicang(ST4) areas, we applied each mean of left and right temperature to statical analysis. Results: In the group of electroacupuncture stimulation at Xingjian(LR2), temperature of every fixed areas on face fell: Jingming(BL1) area's ${\Delta}T=-0.7007{\pm}0.78642$, Sibai(ST2) area's ${\Delta}T=-0.6280{\pm}0.56439$, Dicang(ST4) area's ${\Delta}T=-0.5940{\pm}0.60179$, Indang area's ${\Delta}T=-0.7200{\pm}0.64515$, Shuigou(GV26) area's ${\Delta}T=-0.6160{\pm}0.80487$, Chengjiang(CV24) area's ${\Delta}T=-0.5627{\pm}0.72615$. In Xingjian(LR2) electroacupuncture group, each temperature of Jingming(BL1), Sibai(ST2), Indang areas showed a drop significantly in comparison with control group (p<0.05). But each temperature of Dicang(ST4), Shuigou(GV26), Chengjiang(CV24) areas did not showed a drop significantly in comparison with control group(p>0.05). Conclusions: The results mentioned above showed that electroacupuncture stimulation at Xingjian(LR2) significantly decreased the temperature on face of patients with upperpart fever of human body. In Xingjian(LR2) electroacupuncture group, especially temperature of upper part of face includes eye, cheekbone, forehead regions showed a drop significantly in comparison with control group.

Objectives : Recently, herbal acupuncture has been developed in the Korea since the earlier 1960' applied to various diseases including the cerebrovascular accident. The main characteristics of herbal acupuncture are a combination the merit of acupuncture and herbal medicine. It was not well known the therapeutic effect and the mechanism of herbal acupuncture on transient forebrain ischemic injury, although it has been used frequently in clinics. Ramulus Uncariae Cum Uncis (釣鉤藤) has been claimed to possess sedative, anti-spasmodic actions, and treat childhood epilepsy in oriental medical preparation. Also, it has been stated that Ramulus Uncariae Cum Uncis was antioxidatvie effect and neuroprotection against glutamateinduced neuronal death. Methods : In this study, effects of Ramulus Uncariae Cum Uncis' herbal acupuncture on the $GV_{20}{\;}or{\;}LR_3$, named Baek-hue or Tae-chung, on neuroprotection after the transient forebrain ischemia were investigated in Sprague-Dawely rats. Expressions of cFos, FosB and BDNF protein in the hippocampus and cortex were observed at 2 hrs and 48 hrs after transient forebrain ischemia by immunohistochemistry and ELISA technique. Results : Expression of cFos protein was increased slightly in the hippocampus and cortex at 2 hrs after transient forebrain ischemia, but FosB protein was increased highly comparing to cFos protein. However, pretreatment with Ramulus Uncariae Cum Uncis' herbal acupuncture on $GV_{20}{\;}or{\;}LR_3$ significantly increased expression of cFos protein and significantly decreased expression of FosB protein compared to control group, respectively. These features were observed in the motor cortex and retrosplenial granular cortex as well as the hippocampus. Especially, cFos expression was more increased at the herbal acupuncture on $GV_{20}{\;}than{\;}LR_3$, but FosB expression was more decreased in $LR_3$ group than $GV_{20}$ group. Also, pretreatment with Ramulus Uncariae Cum Uncis' herbal acupuncture on $GV_{20}{\;}or{\;}LR_3$ significantly increased the expression of BDNF protein in the hippocampus ($254.88{\pm}12{\;}pg/ml{\;}in{\;}GV_{20}$ group, $245.93{\pm}44.4{\;}pg/ml{\;}in{\;}LR_3$ group) and the cortex ($85.81{\pm}3.45{\;}pg/ml{\;}in{\;}GV_{20}$ group, $111.51{\pm}15.79{\;}pg/ml{\;}in{\;}LR_3$, group) compared to the hippocampus ($134.07{\pm}2.96{\;}pg/ml$) and the cortex ($61.16{\pm}4.11{\;}pg/ml$) in control group at 48 hrs after transient forebrain ischemia. Conclusion : These results suggest that pretreatment with Ramulus Uncariae Cum Uncis' herbal acupuncture on $GV_{20}{\;}or{\;}LR_3$ has neuroprotective effect on transient forebrain ischemia and the herbal acupunture on $GV_{20}{\;}or{\;}LR_3$ may be related to antioxidative effect and calcium channel block of Ramulus Uncariae Cum Uncis. Also, it could be mentioned there is specificity of acupoints treating ischemic injury through the difference between the herbal acupuncture of $GV_{20}{\;}and{\;}LR_3$.

In the recently, increased concern has been focused on the pharmacology and clinical utility of herbal extracts and derivatives as a drug or adjunct to chemotherapy and immunotherapy. Here we investigated the effect of the water extract of Loranthi Ramulus (LR) in production of inflammatory mediators and expression of toll-like receptor (TLR)-4, CD14 from peritoneal macrophage. We assayed the effect of LR water extract in cell proliferation in vitro and Th1/Th2 cytokine level in vivo. In peritoneal macrophages, water extract of LR water extract increased the production of Nitric oxide (NO) and $TNF-{\alpha}$. Also, LR water extract increased Con A-induced cell proliferation and IgG1, IgG2a level in serum. However, i.p. injection of water extract of LR water extract did not affect the level of $TNF-{\alpha}$, $IFN-{\gamma}$, IL-2, IL-4 and IL-5 in serum of mice. These studies indicate that LR water extract induces macrophage activation and suggest the possible use of LR water extract in macrophage-based immunotherapies.
