  • The psycho-pharmacological effect of BRHAT VATACHINTAMANI RASA (BVC) an Ayurvedic preparation was investigated, both in animal and clinical models. It was observed that BVC possess a sedative or quitening effect in that it significantly decreased the spontaneous motor activity, and also lowered the exploratory behavior of the amphetamine treated animals. This was further evident by increase in climbing out time and taming effect on animal in isolation induced aggression test. Apart from very high dose it seems have little effect on pentobarbital sleeping time and narcotic analgesic test. The drug BVC increases performance of the animal in forced locomotor test. The effect of VATACHINTAMANI RASA on clinical study was not significant.

  • We compared impulsive behaviors in Wistar rats and in Wistar-Kyoto rats. There was no significant difference in locomotor activity between them. However, Wistar rats showed high activity in 5-choice serial reaction time track. When Wistar rats were treated with atomoxetin (3 mg/kg), methylphenidate (2 mg/kg) or amphetamine (2 mg/kg), they showed less impulsive behavior. Serotonin contents in prefrontal cortex and brain stem also increased. In conclusion, we suggest that Wistar rats could be used as animal model for impulsive behavior analysis. In addition, serotonin might be related with this impulsivity.

  • Aphasia is frequent in stroke patients and most patients with aphasia exhibit spontaneous progressive improvement in language abilities over time, but few recover completely. Neurological variables, especially initial severity of aphasia and time post-onset, appear to have influence on improvement. Effect of speech therapy and pharmacotherapy has been studied and some drugs, like amphetamine are proved to be benefit for recovery of aphasia following stroke. But there has been few evidence to facilitate recovery from aphasia by acupuncture or herbal medication therapy. So we report two cases of aphasic stroke patients who treated by combination therapy of acupuncture, herbal medication(Cheongsinhaeo-tang) and speech therapy over 6 months and improved in language abilities. Further clinical studies will be needed to explore the effects of acupuncture and herbal medication therapy for aphasia. Researchers should examine the long term effect of these treatment, and whether it is more effective than speech therapy and western pharmacotherapy or not..

  • 동물의 일반활동은 중추신경계에 작용하는 약물에 관한 많은 정보를 제공한다. 따라서 약물의 중추신경계에 대한 독성평가는 물론이고 중추신경계 작용약물의 검색에도 널리 이용된다. 본 연구에서는 여러 가지 기전으로 중추신경계에 작용하는 약물들의 일반활동을 분석하여 중추신경계 작용 약물들의 작용기전에 따르는 일반활동의 특성을 비교 분석하고자 하였다. 실험장치는 UGO BASILE제 활동측정 장치를 이용하였으며, 실험동물은 서울대학교 의과대학 실험동물 사육장에서 사육한 ICR mouse를 사용하였다. 동물의 활동측정은 환경요인을 최소한으로 배제하기 위하여 매일 9:00-11:00 까지 2시간 동안의 행동을 10분 간격으로 측정 기록토록 하였다. 중추신경 흥분제 amphetamine, 진정수면제 phenobarbital, 항불안제 diazepam, 항정신병약 chlorpromazine, 항우울제 haloperidol는 모두 용량 의존적으로 동물의 자발운동에 영향을 미쳤다. 특기할 것은 항불안제 diazepam 은 용량의존적으로 운동 억제를 나타내었으나 진정수면제 phenobarbital의 경우는 용량 의존전 운동억제를 나타내기 이전에 초기약물 유발성 aggressive behavior를 나타내었다. 본 실험결과는 동물의 자발행동의 분석으로 중추신경계 작용약물의 작용기전 규명 및 이에 따르는 약물의 분류 방법으로 유용하게 이용될 수 있을 것으로 생각된다.

  • The objective of the present study was to assess the antipsychotic and antidiarrhoeal activities of ethanolic extract of roots of Rubia cordifolia in mice and rats. The antipsychotic activity of ethanolic extract of roots of Rubia cordifolia (ERC) was evaluated by observing its effect on amphetamineinduced stereotyped behavior in mice. Effect of ERC was also studied on motor coordination and locomotion in mice. The antidiarrhoeal activity was evaluated using castor oil-induced diarrhoea and excretion of sodium and potassium ions in the intestinal secretion in rats and gastrointestinal transit in mice. The ERC inhibited amphetamine-induced stereotyped behaviour, diminished locomotion and impaired motor coordination. ERC inhibited castor oil-induced diarrhoea, decreased both sodium and potassium excretion in the intestine and decreased gastrointestinal transit. Thus the present study confirms the anti-diarrhoeal activity of Rubia cordifolia. Further studies are necessary to evaluate the potential of Rubia cordifolia as an antipsychotic.

  • Saponin, essential oil and fat oil fractions were fractionated from Panax Ginseng and their potentiating or inhibiting actions during the combined use of several central nervous system stimulants or depressants were observed to elucidate the possible role of Ginseng fractions on the central nervous system. Saponin, essential oil and fat oil fractions shortened nembutal sleeping time at low dosage (10 mg/kg) but contrarily they produced potentiation of nembutal hypnosis at high dosage (50mg/kg). In the toxicity study of amphetamine, saponin and essential oil fractions reduced the toxicity in aggregated mice at high dosage (100 mg/kg) but such decreased lethality was not observed in isolated mice. Ginseng fractions, especially high dose of saponin fraction (100mg/kg) prolonged the survival time after injection of convulsive dose of metrazol or cocaine and saponin fraction also prolonged the onset of cocaine convulsion at high dosage (100 mg/kg).

  • 주의력결핍 과잉행동장애는 미국에서 약 200만 명의 어린이에게 나타나는 심각한 만성 신경행동학적 장애이다. 주의력결핍 과잉행동장애 치료의 중심은 약물요법이다. 그러나 현재 환자의 약 30%는 주의력결핍 과잉행동장애를 적응증으로 갖도록 허가된 의약품들을 사용해도 적절한 치료효과를 얻지 못하고 있는 상황이다. Modafinil은 methylphenidate나 amphetamines와 같은 각성제와는 다른 약리학적 기전으로 중추신경계를 항진시킨다. 본 연구는 modafinil의 주의력결핍 과잉행동장애 치료효과에 대한 최신 지견을 얻고자, 1990년부터 2010년 3월까지 MEDLINE에 등재된 논문을 ADHD와 Modafinil이라는 MeSH terms로 검색하여 추출한 자료 중에서 대조군이 사용된 무작위 배정 및 이중맹검 임상연구 사례만을 선별하여 임상적 유용성을 평가하였다. 현재 modafinil은 주의력결핍 과잉행동 장애 치료제로 허가된 의약품은 아니지만 최근 여러 국가에서 시행된 연구들은 modafinil이 안전하고 효과적인 주의력결핍 과잉행동장애 치료제일 수 있다는 결과를 보여주고 있다.

  • Fatigue has been a common symptom of warfighters who were participated in the early morning hours, late night hours, and sustained operations. Continuous operations may disrupt circadian rhythm, resulting in impaired combat capability. It is important to enhance alertness and sleep quality of warfighters for maintaining combat capability. A number of anti-fatigue strategies are available including medications. Here in, the pharmacological countermeasures of combat fatigue have reviewed, and the direction of research in the pharmacological countermeasures against combat fatigue are proposed.

  • Dopamine transporter (DAT) plays the most important role in terminating the actions of dopamines released into the synaptic cleft. DAT is also the target of various psychotropic drugs such as cocaine and amphetamine. In this study were prepared DAT-specific antibodies using the 2nd extracellular loop of rat DAT as an antigen. The 2nd extracellular loop of the rat DAT was expressed in bacterial as a fusion protein with glutathione-S-transferase, and injected ito rabbits to raise antibodies. Produced antibodies clearly recognized the rat DAT in ELISA, immunoblotting, and immumoprecipitation. As expected from the high sequence homology between the rat and human DAT, the antibodies raised for the rat DAT cross-reacted with the human DAT in the immunoblotting. Considering the specificity for DAT with wide range of applications such as ELISA, immunoblotting, and immunoprecipitation, these antibodies would be valuable tool for understanding the pharmacological actions of dopamine transporter and drug addition.
