목 적: 이 생체 내 연구의 목적은 인도메타신과 비교했을 때 쥐의 원발성 월경통에 대한 계지 복령환 열수 추출물의 진통 및 개선 효과를 관찰하는 것이다. 방 법: 랫트 PD 모델을 만들기 위해, Estradiol benzoate를 10일간 투여한 다음 마지막 10회 estradiol benzoate 투여 1시간 후 1 U/kg의 oxytocin을 투여하였다. 계지복령환 열수 추출물을 500, 250 및 125 mg/kg 용량으로 매일 1회씩 10일간 투여하였다. 이후 체중 및 실험 기간 동안의 체중 증가량, 자궁 중량 및 육안부검 소견, 진통 활성을 나타내는 abdominal writhing test, 자궁 조직 내 지질 과산화(Malondialdehyde, MDA 함량) 및 항산화 방어 시스템 - glutathione (GSH) 함량, superoxide dismutase (SOD) 및 catalase (CAT) 활성, Nuclear factor-κB (NF-κB) 및 cyclooxygenase (COX)-2 mRNA의 발현, 자궁의 조직병리학적 변화, tumor necrosis factor (TNF)-α 및 inducible nitric oxide synthase (iNOS)로 나타나는 면역조직 화학적 변화를 관찰하였다. 계지복령환 열수 추출물의 결과는 인도메타신 투여 쥐의 결과와 비교하였다. 결 과: Estradiol benzoate 및 oxytocin 투여 결과, 현저한 체중 및 증체량, 자궁 GSH 함량, SOD와 CAT 활성의 감소와 abdominal writhing 반응, 자궁 지질 과산화(MDA 함량), 자궁 중량, NF-κB 및 COX-2 mRNA 발현의 증가가 TNF-α 및 iNOS 면역반응세포와 염증세포 침윤 증가, 자궁의 충혈 및 확대와 함께 관찰되었다. 이는 전형적인 염증 및 산화 스트레스성 원발성 월경통이 잘 유도되었음을 의미한다. 한편 이러한 소견은 계지복령환 열수 추출물의 투여에 의해 용량의존적으로 현저히 억제되었으며, 인도메타신의 억제 효과보다는 낮았다. 결 론: 이 연구에서 얻은 결과는 계지복령환 열수 추출물이 estradiol benzoate 및 oxytocin으로 유도된 원발성 월경통에 용량-의존적으로 유리한 진통 및 개선 활성을 가짐을 시사한다.

A number of 4-hydroxy-2H (or alkyl)-N-(3-aralkyl-2-thio-1-hydantoinyl)-1, 2-benzothiazine3-carboxamide 1, 1-dioxides were synthesized through the reaction of 4-hydroxy-2H (or alkyl)1, 2-benzothiazine-3-carboxylic methyl ester 1, 1-dioxide and 1-amino-2-thio-3-aralkyl-4-imidazolones in xylene. The compounds synthesized were screened for antinflammatory effect on carrageenin-induced edema in rat and for analgesic effect on acetic acid-induced Writhing syndrome in mice. Most compounds were inhibots of carrageenin-induced rat foot edema and some showed significant antinflammatory activity comparable to that of indomethacin and significant analgesic activity comparable to that of indomethacin and aspirin.

To elucidate the effects of Chokyungsan and Chunkeunchokyungtang, after oral administration of Chokyungsan and Chunkeunchokyungtang water extract in mice and rats, acute toxicity, analgesic, sedative, esoogenic actions, action on isolated uterine muscle were measured. The rlesults obtained were as follows: 1. The yield of water extract of Chokyungsan and Chunkeunchokyungtang was 24.5%, 32.2%, minimum lethal dose was 4,000mg/kg, which rarely had the acute toxicity in mice and rats. 2. The analgesic effects of Chokyungsan and Chunkeunchokyungtang by acetic acid induced writhing syndrome in mice were not remarkaely observed. 3. The relaxant action of Chokyungsan on on oxytocin induced contracted uterine muscle in estrogenized rats were not remarkably observed, but Chunkeunchokyungtang were remarked. 4. The sedative effects of Chokyungsan and Chunkeunchokyungtang by hexobabital sodium induced sleeping time in mice. 5. administration of Chokyungsan and Chunkeunchokyungtang caused remarkable increase in weight of rat's uterus.

Since 'teaching coding' or 'programming' classes for computational thinking (CT) education in K-12 are renowned around the world, a pre-service teachers' readiness for integrating CT into their teaching subjects is important due to the fact that CT is considered to be another 'R' from algoRitm for 21st century literacy, in addition to the traditional 3R (Reading, Writhing, and Arithmetic) [2] and CT roles to other disciplines. With this rationale, we designed a guided instruction based CT course for pre-service teachers. We show the effectiveness of the program with respect to the teachers' attitude toward combining CT into their teaching subjects, and mindset changes of learning computing connected with the career development of the teacher themselves. The research focused on the instructional methodology of teaching programing for non-Computer Science Education (CSE) majors who are not familiar with computer science for alleviating the cognitive load of first exposure to programming course under the CT concepts.

In this study we fed control diet and tryptophan supplemented diets containing 0.35% tryptophan to ICR mice for 2 weeks. The concentrations of serotonin and 5-HIAA were changed by injection of the serotonin synthesis inhibitor, p-CPA and the serotonin precursor, serotoninP and the change of brain serotonin concentration negatively correlated with that of pain sensitivity, and p-CPA and serotoninP also changed the analgesic effect of morphine. The injection of naloxone, the opiate antagonist, resulted in an increase in the writhing frequency, but its antagonistic effect was not significant. The concentration of 5-HIAA elevated in mice brain at least 3hr after administration of morphine hydroxide indicates that the changes in brain serotonin metabolism may be associated with the acute effects of morphine analgesia. In short, these results not only suggest that tryptophan supplemented diet suppress pain sensitivity in mice, but also indicate that at least in part analgesic mechanism of serotonin may be associated with morphine analgesia.

General pharmacological properties of (R)-JG-381 were examined in laboratory animals to investigate its safety profile. Administration of (R)-JG-381 (50 and 100 mg/kg) in mice and rats had no effects of general behaviors, central nervous system of the animals in test systems of pentobarbital-induced sleeping time, writhing syndromes induced by 0.7% acetic acid, chemo-shock produced by pentylenetetrazole, and, however, had mild effects on motor coordination. Heart rate and blood pressure were not changed by (R)-JG-381 treatment. (R)-JG-381 also showed mild effects on intestinal propulsion and gastric secretion. These results suggest that (R)-JG-381 dose not exert serious pharmacological effects.

Objective : The purpose of these research was to investigate effects of water extract of Bistortae Rhizoma(BRE) on the hemostasia, anti-inflammatory action and central nervous system. Methods : we used mice and rats administered with the extract of the above herbs. Results : BRE decreased the permeability of evans blue into peritoneal cavity and cotton pellet granuloma formation. BRE did not decrease the acetic acid induced writhing syndrome and the histamine induced mouse paw edema. BRE inhibited the pentylenetetrazole and the strychnine induced convulsion. BRE shortened the bleeding time and plasma prtrombin time. BRE did not affect on the proliferation of Balb/c 3T3 cells. Conclusions : these results suggest that the effects of BRE are the hemostasia, anti-inflammatory action, and mild depressant activity of central nervous system.

The ethanolic extract of Jasminum sambac leaves were tested for its cytotoxicity and possible antinociceptive activity in experimental animals. The extract showed potent cytotoxic activity in brine shrimp lethality assay and the LC50 was found only 25 mg/ml. The extract significantly and dose dependently inhibited the acetic acid induced writhing in mice (56.83%, P < 0.001 and 43.17%, P < 0.001 for 500 and 250 mg/kg body weight, respectively). The results supported its traditional uses.

Roots of Rumex crispus (Rc) (Polygonaceae) has been used as therapeutic agents of acute and chronic cutaneous diseases, cathartics, fever and jaundice in folk medicines. Recently, Seeds of Rc has known as a digestive, an anticancer agent and a remedy of acute hepatitis, among many traditional folk medicines. So far it isn't reported about pharmacological effects of Rumecis Semen. The present study describes the preliminary evaluations of biological activities, anti-inflammatory activity (AA, Carrageenan) analgesic activity (writhing test), and hepatoprotective activities ($CCl_4$), of its methanol extract, ethyl acetate fraction and butanol fraction. Among them butanol fraction showed the highest activity in analgesic acivity.

The synthesis of phenoxyalkanoic acid derivatives and their anti-inflammatory and analgesic activities are described. Analysis of structure-activity relationships shows that in trichlorophenoxy derivatives anti-edematous potency is associated with the presence of 1-thiopropyl moiety and 2 or 40aminopyridyl moiety at $R^{l}$ position contributes to the analgesic activity.
