Cordyceps bassiana is a parasitic fungus and used as a Chinese traditional medicine. It has been called as DongChungHaCho(summer-plant, winter-worm) in China. Acute oral toxicity was examined in male and female ICR mice. Butanol fraction from Cordyceps bassiana(BuCb) was administered orally at a dose of 2,500 mg/kg, 5,000 mg/kg, 10,000 mg/kg. No death and abnormal clinical signs were observed throughout the administration period. The acute toxicity test on mouse did not show any oversign in net body weight gain, food and water consumptions, organ weights, gross pathological findings by different doses of BuCb. Also, biochemical examination revealed no evidence of specific toxicity. These findings show that BuCb has wide margin of safety on acute toxicity with single exposure.

A novel synthetic hexapeptide (SFKLRY-$NH_2$) that displays angiogenic activity has been identified by positional scanning of a synthetic peptide combinatorial library (PS-SPCL). This study was carried out to investigate the irritation of the SFKLRY-$NH_2$ on the skin. The tests were performed on the basis of Korea Food and Drug Administration (KFDA) guidelines. In results, cell toxicity is not appeared for SFKLRY-$NH_2$ in HaCaT cells and B16F10 cells. SFKLRY-$NH_2$ induced no skin irritation at low concentration ($10{\mu}m$), mild irritation at high concentration (10mM). We consider that this result is helpful for saying about the safety of SFKLRY-$NH_2$ in clinical use.

Phytochemical constituents were isolated from Pinus koraiensis needles by open column chromatography. The structures isolated from the ethyl acetate fraction of P. koraiensis needles were elucidated as afzelin (1) and quercitrin (2) on the basis of spectroscopic analyses including $^1H$-NMR and MS. The amounts of afzelin (1) and quercitrin (2) in genus Pinus were determined by HPLC/UV analysis. Afzelin (1) and quercitrin (2) contents were highest in P. thunbergii needles. Because P. thunbergii needles contain high amounts of afzelin (1) and quercitrin (2), they have promising potential as new additives to natural medicinal products, health supplements, and beverages.

Objectives : This research was performed to investigate the effects of Fructus Hordei Germiniatus-herbal acupuncture(HA; herbal acupuncture) at acupoint Jung-wan($CV_{12}$) on weight gain, food consumption, food efficiency, serum of lipid concentrations and liver function of rats fed high fat diet for 7weeks. Methods : Experimental groups were divided into high fat diet group(Control), high fat diet and saline injection at acupoint $CV_{12}$ treated group(Saline), high fat diet and Fructus Hordei Germiniatus-HA at acupoint $CV_{12}$ treated groups. According to HA concentration, HA groups were classified into 4 groups ; HA-1($0.108mg/g/m{\ell}$), HA-2($0.054mg/g/m{\ell}$), HA-3($0.022mg/g/m{\ell}$), HA-4($0.011mg/g/m{\ell}$). HA was treated at $20{\mu}{\ell}$ per 4days, total 12times in 49days. Results : 1. Body weight per week was significantly decreased in HA-1, HA-2, HA-3 and HA-4 And body weight per day was significantly decreased in HA-3. 2. Food consumption per week was significantly decreased in HA-1, HA-2, HA-3 and HA-4. 3. Food efficiency per week was significantly decreased in HA-2, HA-3 and HA-4 And food efficiency per day was significantly decreased in HA-3. 4. The level of serum total cholesterol was significantly decreased in HA-1 and HA-3 And the level of serum HDL-cholesterol was significantly decreased in HA-1. 5. The level of serum triglyceride was significantly decreased in HA-1, HA-2, HA-3 and HA-4. And the level of serum total bilirubin was significantly decreased in HA-1and HA-2. 6. The level of serum AST was significantly decreased in HA-2 and HA-3 And the level of serum ALT, r-GTP were significantly decreased in HA-2. Conclusions : According to the above results, Fructus Hordei Germiniatus-HA at acupoint $CV_{12}$ can control body weight, food consumption, food efficiency, serum lipid concentrations and liver function. Asthe same time this kind of Fructus Hordei Germiniatus-HA does not seem to be injurious on liver function. To use Fructus Hordei Germiniatus-HA for obesity, further studies about their underlying mechanism may be needed.

Cordyceps militaris, a member of Ascomycota, a mushroom referred to as caterpillar Dong-chung-ha-cho, is commercially valuable because of its high content of bioactive substances, including cordycepin, and its potential for artificial cultivation. Cordycepin (3'-deoxyadenosine) is highly associated with the pharmacological effects of C. militaris. C. militaris is heterothallic in that two mating-type loci, idiomorph MAT1-1 and MAT1-2, exist discretely in two different spores. In this study, nine C. militaris strains were mated with each other to prepare newly bred strains that produced a larger amount of cordycepin than the parent strains. Nine strains of C. militaris were identified by comparing the internal transcribed spacer sequence, and a total of 12 single spores were isolated from the nine strains of C. militaris. After the MAT idiomorph was confirmed by PCR, 36 mating combinations were performed with six single spores with MAT1-1 and the others with MAT1-2. Eight mating combinations were successfully mated, producing stroma with perithecia. Cordycepin content analysis of all strains by high-performance liquid chromatography revealed that the KASP4-bred strain produced the maximum cordycepin among all strains, regardless of the medium and stroma parts. Finally, universal rice primer-PCR was performed to demonstrate that the bred strains were genetically different from the parental strains and new C. militaris strains. These results may be related to the recombination of genes during mating. The newly produced strains can be used to meet the industrial demand for cordycepin. In addition, breeding through mating suggests the possibility of producing numerous cordycepin-producing C. militaris strains.

Three different dutasteride extraction methods were compared and a method based on liquid-liquid extraction (LLE) using methyl tert-butyl ether and methylene chloride was proved to be more effective than others for the extraction of dutasteride and finasteride, the internal standard (IS), from rat plasma. Additionally, a method composed of the LLE extraction, liquid chromatography, and multiple reaction monitoring (MRM) to target dutasteride and IS was validated by assessing specificity, linearity ($r^2$ = 0.9993, 5 - 400 ng/mL), sensitivity (the limit of detection: 4.03 ng/mL; the limit of quantitation: 12.10 ng/mL), accuracy (intra-day: 89.4 - 105.9%; inter-day: 84.9 - 100.9%), precision (intra-day: 0.8 - 6.9%; inter-day: 2.9 - 15.9%), and recovery (84.7 - 107.8%). Since the validated method was successfully applied to a pharmacokinetic study of dutasteride, it can be useful for the pharmacokinetic evaluation of newly developed dutasteride formulations.

Signet ring cell carcinoma is a rare type of mucinous adenocarcinoma of the uterine cervix. To the best of our knowledge, there is no report on cytologlc findings of primary signet ring cell carcinoma of the uterine cervix in the literature. Recently, we experienced two cases of signet ring cell carcinoma of the uterine cervix. The finding of characteristic signet ring cells on cervicovaginal smear led to the diagnosis of signet ring cell carcinoma. However, primary signet ring cell carcinoma could not be cytologically distinguished from more common metastatic tumor. Therefore, diagnosis rests upon the recognition of signet ring cells and the absence of signet ring cell carcinoma elsewhere.

Objectives : The aim of the present study was to observe the effect of Astragali Radix Herbal-Acupuncture Solution(AR-HAS) at $ST_{36}$(jok-samni, $Z\acute{u}s\bar{a}n$ Li) on collagen- II -induced arthritis(CIA) in mice. Methods : DBA/1J mice were immunized with bovine type II collagen(CII) on days 0 and 21 to induce arthritis. The mice were divided into 5 groups : normal group(no CIA), control group(CIA+no treatment), needle prick group(CIA+single prick with an injection needle), saline group(CIA+saline injection) and ARHA group(CIA+ R-HA treatment). The needle prick, saline injection, and AR-HA groups were injected on the right $ST_{36}$(jok-samni) of mice for 9 weeks, 3 times a week, beginning 4 weeks after the booster immunization. Results : 1. The incidence of arthritis, AI(arthritis index), and joint edema decreased in the AR-HA group. 2. Weight gain, hypertrophy of the spleen, adhesion of the tissues, and transformation of the joint were restrained in the AR-HA group. 3. The concentrations of $IL-1{\beta}$, IL-6, $TNF-{\alpha}$, $IFN-{\gamma}$ in CIA mouse serum and $IFN-{\gamma}$, IL-10 in the CIA mouse spleen cell culture decreased significantly at $ST_{36}$ in the AR-HA group. 4. Total cell counts increased significantly, and the ratio of $CD3e^+$ to $CD45R^+$, $CD4^+$ to $CD8^+$, and $CD4^+$ to $CD25^+$ cells decreased significantly at $ST_{36}$ in the CIA mouse spleen cell culture of the AR-HA group. 5. Total cell counts decreased significantly, and $CD4^+/CD25^+$ and $CD45R^+/CD69^+$ decreased significantly at $ST_{36}$ in the CIA mouse lymph nodes of the AR-HA group. 6. $CD3e^+/CD69^+$ and $CD11b^+/Gr-1^+$ cells decreased significantly at $ST_{36}$ in the CIA mouse joints of the AR-HA group. 7. The histological examination showed that cartilage destruction and synoviocyte proliferation decreased in the CIA mouse joints of the AR-HA group, and collagen fiber was expressed similar to that seen in the normal group. Conclusions : Our experiments show that at $ST_{36}$, an anti-inflammatory mechanism of AR-HA controls synovial cell proliferation and protects against cartilage destruction in rheumatoid arthritis.
