In order to investigate the pharmacological activities of the combined preparation of crude drugs, Chunghyulgangki-Tang was studied. Chunghyulgangki-Tang has been widely used to cerebral apoploxy, hypertension and arteriosclerosis, etc. In this study, water extract of Chunghyulgangki-Tang was conducted in attempt to investigate for analgesic, sedative, antipyretic, isolated ileum and heart, blood vessels and blood pressure action in mice, frogs, rats, guinea-pigs and rabbits. The following results were obtained; Analgesic action by the acetic acid stimulating method in mice was recognized. Sedative activities by the wheel cage method and rotor rod method in mice were shown. Prolonged action against the hypnotic duration induced by thiopental-Na was significantly noted in mice. The effect of antipyretic in endotoxin febrile rats was significantly recognized. Spontaneous motility of the isolated ilem of mice was suppressed and contractions of the isolated ileum of mice and guinea-pigs induced by acetylcholine chloride, barium chloride and histamine were remarkably inhibited. Acceleration of isolated heart motility was shown in frogs. Vaso-dilating and hypotensive actions were recognized in rabbits. According to the above results, effects based on the oriental medicinal references were approximate to the actural experimental results.

It has long teen known in herbal medicine that the mugwort not only exerts a strong hemostatic and parasiticidal actions but also has therapeutic effects for stomachache and diarrhea. In recent pharmaceutical botany the mugwort is known to have antipyretic and astringent actions also. Among the major principles which have been found in the leaves and stems of mugwort are inulin, alkaloids, vitamines, and esestial oil. It is well known that santonin, one of the well known parasiticides, is one of the glucosides extracted from the limited species of mugwort. The present study was undertaken to investigate effects of mugwort(Artemisia asiatica Nakai) on the motility of isolated rabbit duodenum. The results obtained are as follows: At does of 0.2%, 0.5% and 1. 0% AAJ(Artemisia asiatica juice) markedly enhanced contractility of isolated duodenum and tonus of the intestine was also augmented with doses of 0.5% and 1.0%. The augmentative effect of AAJ on intestinal motility was not affected by pretreatment with epinephrine and avil while it was completely abolished by atropine. Therefore it is strongly suggested that augmentative action of AAJ on duodenal motility was exerted solely through muscarinic cholinergic receptors.

From the perspective of the definition of pain, pain can be divided into emotional and sensory components, which originate from potential and actual tissue damage, respectively. The pharmacologic treatment of the emotional pain component includes antianxiety drugs, antidepressants, and antipsychotics. The anti-anxiety drugs have anti-anxious, sedative, and somnolent effects. The antipsychotics are effective in patients with positive symptoms of psychosis. On the other hand, the sensory pain component can be divided into nociceptive and neuropathic pain. Non-steroidal anti-inflammatory drugs (NSAIDs) and opioids are usually applied for somatic and visceral nociceptive pain, respectively; anticonvulsants and antidepressants are administered for the treatment of neuropathic pain with positive and negative symptoms, respectively. The NSAIDs, which inhibit the cyclo-oxygenase pathway, exhibit anti-inflammatory, antipyretic, and analgesic effects; however, they have a therapeutic ceiling. The adverse reactions (ADRs) of the NSAIDs include gastrointestinal problems, generalized edema, and increased bleeding tendency. The opioids, which bind to the opioid receptors, present an analgesic effect only, without anti-inflammatory, antipyretic, or ceiling effects. The ADRs of the opioids start from itching and nausea/vomiting to cardiovascular and respiratory depression, as well as constipation. The anticonvulsants include carbamazepine, related to sodium channel blockade, and gabapentin and pregabalin, related to calcium blockade. The antidepressants show their analgesic actions mainly through inhibiting the reuptake of serotonin or norepinephrine. Most drugs, except NSAIDs, need an updose titration period. The principle of polypharmacy for analgesia in case of mixed components of pain is increasing therapeutic effects while reducing ADRs, based on the origin of the pain.

Mefenamic acid has been widely used as clinical drug for anti-inflammatory and analgesic. This drug was known to non-steroidal anti-inflammatory drugs (NSAIDs) such as aspirin, ibuprofen and indomethacin. Although the drugs which comprise this group are of diverse chemical structures, they all share the antipyretic, analgesic and anti-inflammatory actions which are characteristic of aspirin. Action of this drugs is caused by inhibitory effect of biosynthesis of prostaglandin that are synthesized from arachidonic acid via the endoperoxide biosynthesis pathway, the initial step of which is catalysed by cyclooxygenase. Mefenamic acid has more potent inhibitory action of prostaglandin biosynthesis than aspirin. Therefore, mefenamic acid is expected to have anticoagulant activity as aspirin-like drugs. This study was carried out to investigate the sinthesis of mefenamic acid derivatives from mefenamic acid and aromatic compound of antioxidant and its antioxidative and anticoagulant activities. Synthesis of mefenamic acid derivatives was conformed by conjugation as using esterification method. Biological activities was examined using effect of anticoagulant on bleeding time and effect of antioxidant by TBA method. As a result, SJ-202 showed strong antioxidative activity and anticoagulant activity among tested 4 compounds and exhibited similar activity to aspirin at anticoagulant activity.

Panax ginseng C.A. Meyer(Araliaceae) has been traditionally used as an expensive and precious medicine in oriental countries for more than 5, 000 years. Ginseng saponin isolated from the root of Panax ginseng have been regarded as the main effective components responsible for the pharmacological and biological activities. Such as antiaging effects. antidiabetic effects anticancer effects. Protection against physical and chemical stress. Analgesic and antipyretic effects. Effects on the central nervous system, tranquilizing action and others. Thirty kinds of ginsenosides have been so far isolated from ginseng saponin and their chemical structures have been elucidated since 1960's. Among which protopanaxadiol type is 19 kinds. protopanaxatriol type. 10 kinds and oleanane type, one. Since ginsenosides are generally labile under acidic conditions ordinary acid hydrolysis is always accompanied by many side reactions, such as epimerization. hydroxylation and cyclization of side chain of the sapogenins Especially. it is well known that C-20 glycosyl linkage of ginsenoside was hydrolysed on heating with acetic acid to give an equilibrated mixture of 20(S) and 20(R) epimers. And also, the chemical transformations of the secondary metabolites have appeared during the steaming process to prepare red ginseng. Indicating demalonylation of malonyl ginsenosides, elimination of glycosyl residue at C-20 and isomerization of hydroxyl configuration at C-20. But these studies have not provided a comprehensive picture in explaning how these ginsenosides showed val'iotas pharmacological activities of ginseng. Though some of them have been involved in the mechanism of pharmacological actions. Recently, non-saponin components have received a great deal of attention for their antioxidant, anticancer antidiabetic, immunomodulating. anticomplementary activities and so on. To meet the demand for such wide applications, studies on the non-saponin components play an important role in providing a good evidence of pharmacological and biol ogical activities. Among the non-saponin constituents of Korean ginseng, polyacetylenes, phenols. Sesquiterpenes, alkaloids. polysaccharides oligosaccharides, oligopeptides and aminoglycosides together with ginsenosides of terrestrial part are mainly described.

The wormwood is one of the plants which occur widely throughout the world. Though the precise data on the entire chemical composition of mugwort leaves are not available, the major principles which have been found so far include inulin, alkaloid, thujon, sesquiterpene and several vitamins. Santonin, a parasiticide, is one of the glucosides extracted from the limited species of wormwood. It has long been known in herb medicine that the plants of this family has not only strong hemostatic, analgesic and parasiticidal actions but also therapeutic effects for diarrhea, stomachache and asthma. In recent pharmaceutical botany the wormwood is introduced to have antipyretic and astringent actions also. The mugwort(Artemisia asiatica Nakai) is the most common species of wormwood that occurs in Korea. The usage of this edible leaves of mugwort is rather various. It is used not only for wormwood bath but also as forage, moxa and medicinal agents. Recently Kim et al reported from their study on the effect of mugwort on the motility of isolated intestine of rabbits that tonus and motility were markedly enhanced by mugwort but this effect of mugwort on intestinal motility was almost completely blocked by atropine suggesting that activity of mugwort was exerted through its cholinergic effect. It was the findings of Kim et al that prompted the authors to do the present experiment. The present study was undertaken to investigate effects of mugwort(Artemisia asiatica Nakai) juice on the respiration and blood pressure in cats. And also studied was the mechanism of depressor action of Artemisia asiatica Nakai Juice (AAJ). The results obtained are as follows; 1) It was observed that mean arterial blood pressure and heart rate were decreased markedly by AAJ. Following administration of 0.15 ml/kg and 0.3 ml/kg AAJ into cats the maximum depressor responses observed were $77.5{\pm}2.2\;mmHg$ and $94.0{\pm}3.7\;mmHg$ respectively. 2) Depressor responses to AAJ were blocked markedly by atropine whereas the responses were not affected by propranolol and dibenamine. Therefore it is strongly inferred that depressor action of AAJ results mainly from its cholinergic effect. This inference was further substantiated by the fact that heart rate change which invariably accompanies depressor responses to AAJ was almost completely abolished by atropinization. 3) After administration of AAJ into cats frequency of respiration was markedly increased while depth of respiration decreased during first 2-3 seconds.

본 연구는 중앙대서전에 인삼의 주 효과중 건망증 방지작용이라고 수록되어 있는 것을 확인하기 위하여 행하여졌다. Step through 시험에서 $GRb_1$과 $GRg_1$은 기억력 획득을 용이하게 하였으며 전기충격 쇼크에 의해 야기되는 기억상실 효과를 억제하였다. 게대가 $Rg_1$은 에타놀 야기 기억재생 저해작용을 방지하였다. Stepdown test에 있어서 $Rb_1,\;Rb_2,\;Rg_1$은 전기충격쇼크에 의해 야기되는 기억보지 저해효과를 방지하였다. 또한 $Rg_1$은 에타놀에 의해 야기되는 기억재생 저해효과를 방지하였으며 단기적 기억력 획득을 용이케 하였다. Shuttle box와 lever press 시험에서도 $Rb_1$을 제외하고 나머지는 기억획득과 재생에 효과를 미치지 못했다. $Rb_1$은 shuttle box 시험에서 조건회피반응의 재생 (retrieval)을 억제하였다. 이와 같은 4가지 시험이 끝난후에 인삼의 구강투여가 진정, 진통, 해열, 진경효과와 자발 및 탐색활동에 미치는 영향을 500 mg/kg 투여 범위내에서 조사하였으나 아무런 반응도 관찰되지 않았다. 현재까지 연구결과는 $Rg_1$이 기억의 재생 및 학습반응의 획득과정에 대하여 효과가 있다는 것을 의미한다. 최근의 신경성장인자(NGF)가 성숙동물에 있어 뇌신경세포의 생존, 재생 및 조절에 미치는 작용에 관한 연구결과는 지능장해와 건망증에 대한 신경성장인자의 중요성을 시사했다. NGF에 의해 야기된 신경세포돌기 성장의 특이성에 관한 연구결과를 병아리 배배근 신경절에 있어서 NGF의 영향은 $Rh_1$에 의해 증가되었다. 다음으로 $Rb_1$은 병아리 배의 감각 및 교감신경단위에 있어서 NGF-관련 신경섬유 증가를 강화시켰다. NGF와 $Rb_1$을 함께 했을 때도 역시 쥐 대뇌피질의 신경세포 생존수를 증가시키는 경향을 보였다. NGF는 쥐의 배격부 부근의 신경세포를 배양했을 때 cholineacetyl transferase 활성을 증가시키지 않았다. 이러한 결과로 $Rb_1$은 뇌에 있어서 신경세포의 생존이나 재생에 중요한 역활을 한다는 것은 알 수 있었다.
