In order to investigate the effects of Kyegyoksan on antitumor effects after Sarcoma 180 cells transplantation into the peritoneal cavity or left groin in mice, and immune depression in mice induced by methotrexate, the extracts of its herbal medicines were orally administered for 14 or 21 days. Experimental studies were performed for measureance of $IC_{50}$ in MTT assay, mean survival days, tumor and body weights for antitumor effects, delayed type hypersensitivity, hemagglutinine titer, hemolysin titer, rosette forming cells, interleukin-2 productivity, lymphocyte transformation, natural killer cell activity and phagocytic activity for immune responses in the immune depressed ICR mice, and SGOT, SGPT, BUN and creatinine for liver and kidney protective function in SO-rats. The results were obtained as follows: 1. From the results of MTT assay, the Kyegyoksan exstracts for SUN-1 and SUN-C4 were inhibited cell viability. 2. Mean survival time in Kyegyoksan-treated group was slightly increased with no effectiveness, as compared with the control group. 3. Tumor weight in Kyegyoksan-treated group was depressed with the statistical significance, as compared with the control group(p<0.01). 4. Body weight in Kyegyoksan-treated group was incresed with the statistical significance, as compared with the control group(p<0.05). 5. Delayed type hypersensitivity in Kyegyoksan-treated group was slightly incresed with no effctiveness, as compared with the control group. 6. Hemagglutinin titer in Kyegyoksan-treated group was incresed with the statistical significance(p<0.05), but hemolysin titer was slightly incresed with no effectiveness, as compared with the control group. 7. Rosette forming cells in Kyegyoksan-treated group was incresed with the statistical significance, as compared with the control group(p<0.001). 8. Interleukin-2 productivity in Kyegyoksan-treated group was incresed with the statistical significance, as compared with the control group(p<0.001). 9. Lymphocyte transfomation in Kyegyoksan-treated group was incresed with the statistical significance, as compared with the control group(p<0.01). 10. Natural killer cell activity in Kyegyoksan-treated group at E/T ratio 100 : 1 was incresed with the statistical significance(p<0.01), but at E/T ratio 50 : 1 and 10 : 1 was slightly incresed with no effectiveness, as compared with the control group. 11. Phagocytic activity in Kyegyoksan-treated group was slightly incresed with no effectiveness, as compared with the control group. 12. The levels of serum glutamic oxalacetic transaminase, serum glutamic pyruvic transaminase, blood urea nitrogen and serum creatinine in Kyegyoksan-treated group were not effective change, as compared with the control group. According to the above results, it could be suggested that Kyegyoksan have prominent antitumor effects, enhance both cellular and humoral immunity, and have no injury to liver and kidney functions.

The present study was performed in order to evaluate the effects of the gamihyangsayukgunjatang on radioprotection and apoptosis in small intestines of mice after whole body irradiation. Two hundred forty mice were divided into 40 groups according to the radiation dose and the gamihyangsayukgunjatang treatment. The extracts of the herbal medicines were orally administered to each group differently before and/or after irradiation. The gamihyangsayukgunjatang treated groups were divided into 3 groups. Sample Ⅰ was the group treated with the gamihyangsayukgunjatang for 3 days before the radiation, sample Ⅱ was the group treated with the gamihyangsayukgunjatang for 3 days after the radiation. Sample Ⅲ was the group treated with the gamihyangsayukgunjatang for both 3 days before and after the radiation. To analyze the crypt survival, the micradony survival assay was used according to the Withers and Elind's method. To analyze the apptosis, the TUNEL assay was done. The results obtained are a follows : 1. From the microcolony survival assay, the gamihyangsayukgunjatang treated groups showed the radioprotective effect with a statistical significance(p<0.05), as compared to the control group. Comparing the radioprotective effect among the 3 groups, sample III was statistically more significant than sample I and II (p<0.05). Sample I showed no effect. In accordance with the research mentioned above, it is suggested that the radioprotective effect of the gamihyangsayukgunjatang is more useful for the treatment of the radiation injury rather that the prevention. 2. The results of the TUNEL assay showed that the apoptotic index in the gamihyangsayukgunjatang treated group was slightly decreased with no effectiveness, as compared to the control group. According to the above results, it could be suggested that the gamihyangsayukgujatang has a prominent protective effect in mice intestines against the radiation damage. However, the radioprotective effect does not seem to be related to inhibition of the apoptosis.

Objectives: The object of this study was to evaluate the cognition and motor function recovery effects of Sungshim-san (SSS), a traditional Korean cardio-protective polyherbal formula in the severe rat stroke, permanent middle cerebral artery occlusion (pMCAO) model. Methods: The experimental animals were divided into 6 groups. SSS aqueous extracts (yield=16.82%; 400, 200 and 100 mg/kg) were administered orally by using Sonde, once daily, for 28 continuous days from 24 hrs post-pMCAO. Donepezil 10 mg/kg, a representative drug for dementia, was used as a reference drug. The body weight changes, infarct/defect sizes, sensorimotor function and cognitive motor behavior were serially monitored. Limb placing and body-swing test for sensorimotor functions were conducted at 1 day before operation (base line), and 1, 3, 7, 14, 21 and 28 days post-pMCAO; and water maze test for the cognitive motor behavior was conducted at 14 and 28 days post-pMCAO, respectively. Results: Focal cerebral cortex infarct and defects due to pMCAO resulted in marked decreases of body weight, disorders of sensorimotor functions and cognitive motor behaviors. However, the pMCAO-related ischemic damages were markedly and dose-dependently inhibited by treatment with SSS 400 and 200 mg/kg, respectively. Donepezil markedly decreased the body weight and gains, as compared with pMCAO control rats; however, SSS 400 and 200 mg/kg favorably ameliorated the pMCAO-induced decreases in body weight and gains. SSS 100 mg/kg treated rats did not show any favorable effects on the pMCAO-related ischemic damages, as compared with pMCAO control rats. Conclusions: The results of the study indicated that oral administration of SSS 400 and 200 mg/kg accelerated cognition and motor function recovery in the rat pMCAO model. The treatment effect was potentially mediated by neuroprotection via the known augmentation of cerebral antioxidant defense system of SSS itself or its individual herbal components. Especially, the overall effects of SSS 200 mg/kg were similar to those of donepezil 10 mg/kg, but less toxic.

The traditional herbal medicine, Jackyakgamcho-tang(JGT), was reported to decrease serum testosterone levels and make pregnancy possibel in anovulatory woman and rat. JGT contains Paeoniae Radix(PR) and Glycyrrhizae Radix(GR) in equal amount. This study was designed to investigate the effect of JGT and its components(PR, GR, paeoniflorin and glycyrrhizin) on uterine and ovarian responses, follicular development, and estrogen secretion in the immature rat. The samples(water extracts of JGT, PR, GR; pure compound of paeoniflorin and glycyrrhizin) were administered orally to rats from the 21th day of age to the 28th or 30th days of age for 7 or 9 days. JGT(400mg/kg) and PR(100mg/kg, 200mg/kg) treatments significantly increased serum estradiol above levels in control rats, but both GR and glycyrrhizin had no effect on this parameter. Gross observation and histological analysis revealed that an increased number of growing follicules was observed in the ovaries of JGT and PR treated rat. However the lutenized follicles and ova present in the oviducts were not observed in all rats except one treated with estrogen as a positive control. These results indicate that JGT stimulates the estrogen production and follicular maturation in the immature rat and PR is the main component to induce such reaction.

Objectives: Selaginella bryopteris L. (family: Selaginaceae), is often used in traditional Indian systems of medicine for the prevention and cure of several disorders and for the treatment of patient with spermatorrhoea, venereal disease, constipation, colitis, urinary tract infections, fever, epilepsy, leucorrhoea, beri-beri and cancer. It is also used as a strength tonic. This study aimed to evaluate the mechanisms underlying the anti-inflammatory effects of topically administered aqueous, polar and non-polar methanolic fractions ($10mg/20{\mu}L$) of Selaginella bryopteris. Methods: An acute oral toxicity study of Selaginella bryopteris at doses from 250 to 2,000 mg/kg body weight (bw) was performed. Aqueous, polar and non-polar methanolic extracts ($10mg/20{\mu}L$) applied topically for 5 days were evaluated for their anti-inflammatory effects against 12-tetra-O-decanoyl phorbol acetate (TPA)- induced inflammation by using the redness in the ear, the ear's weight (edema), oxidative stress parameters, such as lipid-peroxide (LPO) and nitric oxide (NO), and the pro-inflammatory cytokines involved in inflammation, such as tumour necrosis factor $(TNF)-{\alpha}$, interleukin $(IL)-1{\beta}$ and IL-6. Indomethacine ($0.5mg/20{\mu}L$) was used for the positive control. Results: Selaginella bryopteris produced no mortalities when administered orally at doses from 250 to 2,000 mg/kg bw. Topical treatment with the non-polar methanolic fraction ($10mg/20{\mu}L$) significantly suppressed redness ($2.4{\pm}0.5$) and edema ($30.4{\pm}1$) and effectively reduced the LPO level ($32.3{\pm}3.3$). The NO level was ($8.07{\pm}0.55$), and the $TNF-{\alpha}$, $IL-1{\beta}$, and IL-6 levels were decreased to $69.6{\pm}15.5$, $7.7{\pm}4.8$ and $82.6{\pm}5.9$, respectively. Conclusion: This study demonstrated for the first time the mechanisms underlying the anti-inflammatory effect of medicinal plants like Selaginella bryopteris and quantified the pharmacological interactions between them. The present study showed this herbal product to be a promising anti-inflammatory phytomedicine for the treatment of patients with inflammatory skin diseases.

진피(Citri Pericarpium)의 항암작용 기전 해석을 위하여 U937 백혈병 세포의 apoptosis 유발에 미치는 메탄올 추출물(EMCP)의 영향을 조사하였으며, apoptosis 조절에 중요한 몇 가지 유전자들의 발현 및 활성 변화, ROS의 생성 변화를 조사하였다. EMCP 처리에 의한 U937 세포의 증식 억제는 apoptosis 유도와 연관성이 있음을 DAPI 염색을 통한 apoptotic body 출현의 증가 및 Flow cytometry 분석에 의한 Sub-G1기 세포 빈도의 증가로 확인하였다. EMCP 처리에 의한 apoptosis 유도에서 Bax 발현 증가, caspases의 활성 및 PARP의 단편화 등이 동반되었으며, ROS 생성의 증가와 연관성이 있었다. 산화적 손상에 대해 세포나 조직을 보호하는 역할을 하는 것으로 알려진 세포 내 항산화 효소인 HO-1의 발현이 EMCP의 처리에 의해 증가되었으나 ROS 생성 억제제인 NAC의 전처리에 의해 감소된 HO-1의 발현은 전사인자인 Nrf2의 핵으로의 이동 억제와 관련되어 있었다. 이상의 결과에서 EMCP 처리에 의한 U937 세포의 apoptosis 유발에는 ROS 생성의 증가와 pNrf2에 의해 조절되는 HO-1의 발현 증가가 중요한 기전으로 작용한다는 것을 알 수 있었다. 이러한 자료는 진피의 항암기전 해석을 이해하는데 중요한 기초자료로서 활용될 수 있을 것으로 생각된다.
