  • Pharmacological effects of water extracts of Lycii Fructus, Lycii Folium and Lycii Cortex Radicis from Lycium chinensis were investigated. Lycii Folium significantly protected the hepatic function from damages orally caused by $CCl_4 $administration in mice and had a strong hypoglycemic effect in hyperglycemic mice induced by streptozotocin. Lycii Fructus decreased the blood pressure rise associated with the growth of normal rats. Lycii Cortex Radicis had a strong hypoglycemic effect in hyrerglycemic mice induced by streptozotocin. Also, hypolipidemic effects in hyperlipidemic rats induced by 1% cholesterol fed-diet and 75% fructose were significantly observed by oral administration of water extracts of Lycii Fructus, Lycii Folium and Lycii Cortex Radicis.

  • Patients with severe gag reflex (SGR) have difficulty getting the treatment they require in local clinics, and many tend to postpone the start of their treatment. To address this problem, dentists have used behavioral techniques and/or pharmacological techniques for treatment. Among the pharmacological methods available, propofol IV sedation is preferred over general anesthesia because it is a simpler procedure. Propofol in combination with remifentanil is characterized by stable sedative effects and quick recovery, leading to a deep sedation. Remifentanil acts to reduce the pain caused by lipid-soluble propofol on injection. The synergistic effects of propofol-remifentanil include reduction in the total amount of drug required to achieve a desired sedation level and anti-emetic effects. In this case report, we outline how the use of propofol-remifentanil IV sedation enabled us to successfully complete a wide range of dental treatments in a patient with SGR.

  • In order to investigate pharmacological properties of ι -muscone, effects of ι-muscone and musk on cerebral ischemia and central nervous system were compared. Cerebral ischemia insult was performed using unilateral carotid artery occlusion in Mongolian gerbils. The histological observations showed a preventive effect of the ι-muscone treatment with ischemia-induced brain damage. The ATP in brain tissue was decreased in vehicle-treated ischemic gerbils. This decrease was prevented by the ι-muscone treatment. In contrast to what was seen with ATP, the lactate and lipid peroxide were both elevated in vehicle-treated ischemic gerbils.˙ This elevation was prevented by the ι-muscone treatment. While ι-muscone had no effects on the hexobarbital-induced sleeping time and the convulsions induced by electric shock, pentetrazol and strychnine, it had effect on rotarod test and spontaneous activity test. Respiration rate and depth were increased by the ι-muscone treatment. Furthermore, ι-muscone showed anti-stress effect. Our findings suggest that the pharmacological profile of ι-muscone on cerebral ischemia and central nervous system are similar to that of musk.

  • 'Kangsim-San' is an added and subtracted prescription of 'Cheongsim-Yeonza-Tang' recorded in 'Dongeuy-Soose-Boweon' from which it has become one of the favorate prescriptions at the Oriental Medical Hospital, Kyung-Hee University. It is described in the book that the 'Cheongsim-Yeonza-Tang' can be effective to symptoms relating to fatigue, nocturnal emission, abdominal pain, tongue deviation and palsy, etc. However the 'Kangsim-San' has been used for neurotic syndrome, pulpitation, insomnia, constipation, dry-mouth, auorexia and arrythmias and so on, added to the above-mentioned symptoms for the 'Cheongsim-Yeonza-Tang' at the hospital. Nevertheless, the pharmacological research of fundamental basis is not completed so far, and we have attempted experiment on various animals to study the pharmacological effects of the medicine. The result was proved as follows; The prescription had a considerable effects on the sedation of central nervous system, antipyretic and analgesic action, and vasodilative action.

  • ln order to investigate pharmacological properties of New Woohwangchungsimwon Liquid (NCL) and Woohwangchungsimwon Liquid (CL), effects of NCL and CL on cerebral ischemia and central nervous system were compared. Cerebral ischemia insult was performed using unilateral carotid artery occlusion in Mongolian gerbils. The histological observations showed a preventive effect of NCL and CL treatments with ischemia-induced brain damage. The ATP in brain tissue was decreased in vehicle-treated ischemic gerbils. This decrease was prevented by CL treatment. In contrast to what was seen with ATP, the lactate and lipid peroxide were both elevated in vehicle-treated ischemic gerbils. This elevation was inhibited by NCL and CL treatments. While NCL and CL had no effects on the hexobarbital-induced sleeping time, they prevented the seizures induced by electric shock and pentetrazol. NCL and CL showed sedative effect in rotarod and spontaneous activity test. Respiration rate and depth were increased at the high dose of NCL and CL. Furthermore, NCL and CL showed anti-stress effect. Our findings suggest that the pharmacological profile of NCL on cerebral ischemia and central nervous system are similar to that of CL.

  • Ginsenoside Rg3 (G-Rg3) contained only in red ginseng has been found to show various pharmacological effects such as an anticancer, antiangiogenetic, antimetastastic, liver protective, neuroprotective immunomodulating, vasorelaxative, antidiabetic, insulin secretion promoting and antioxidant activities. It is well known that G-Rg3 could be divided into 20(R)-Rg3 and 20(S)-Rg3 according to the hydroxyl group attached to C-20 of aglycone, whose structural characteristics show different pharmacological activities. It has been reported that G-Rg3 is metabolized to G-Rh2 and protopanaxadiol by the conditions of the gastric acid or intestinal bacteria, thereby these metabolites could be absorbed, suggesting its absolute bioavailability (2.63%) to be very low. Therefore, we reviewed the chemical, physical and biological transformation methods for the production on a large scale of G-Rg3 with various pharmacological effects. We also examined the influence of acid and heat treatment-induced potentials on for the preparation method of higher G-Rg3 content in ginseng and ginseng products. Futhermore, the microbial and enzymatic bio-conversion technologies could be more efficient in terms of high selectivity, efficiency and productivity. The present review discusses the available technologies for G-Rg3 production on a large scale using chemical and biological transformation.

  • General pharmacological properties of recombinant human parathyroid hormone (hPTH) were examined. The administration of hPTH (7, 35 and 175 lU/kg sc) in mice had no effects in general behavior and central nervous system, and no influences on normal body temperature, writhing syndromes induced by 0.7% acetic acid solution and chemoshock produced by strychnine and pentetrazol solution. hPTH (9 and 44 lU/kg, sc) given to anesthetized rabbits showed no effect on blood pressure of carotid artery and respiration, and it did not influence the responses produced by injection of acetylcholine or epinephrine. It showed no direct effect at 4.4$\times$10$_{-2}$IU/ml in isolated stomach fundus and uterus of rats and ileum of guinea-pig, and it also showed no inhibition of contraction produced by acetylcholine, oxytocin, serotonin and histamine in the above-mentioned preparations. It did not influence intestinal propulsion at the doses of 7,35 and 175 lU/kg sc in mice. This drug exhibited no effect on urinary excretion at the doses of 7 and 35 lU/kg sc in rats. However, at a dose of 175 lU/kg sc, it showed a decreased urination along with decreased excretion of potassium, sodium and chloride ion. These results indicate that hPTH does not exert any of serious pharmacological effects except the inhibition of urination at a highest dose used.

  • In order to investigate pharmacological properties of New Wonbang Woohwangchungsimwon Liquid(NSCL) and Wonbang Woohwangchungsimwon Liquid(SCL), the effects of NSCL and SCL on cerebral ischemia and central nervous system were compared. Cerebral ischemia insult was performed using unilateral carotid artery occlusion in mongolian gerbils. The histological observations showed a preventive effect of NSCL and SCL treatments with ischemia-induced brain damage. The ATP in brain tissue was decreased in vehicle-treated ischemic gerbils. This decrease was prevented by NSCL and SCL treatment. In contrast to what was seen with ATP, lipid peroxide were elevated in vehicle-treated ischemic gerbils. This elevation was inhibited by NSCL and SCL treatments. While NSCL and SCL had no effects on the hexobarbital-induced sleeping time, they showed sedative effect in rotarod and spontaneous activity test. NSCL and SCL prevented the seizures induced by electric shock and strychnine, but the effect of NSCL was less than that of SCL. Furthermore, NSCL and SCL showed anti-stress effect. Our findings suggest that the pharmacological profiles of NSCL on cerebral ischemia and central nervous system are similar to those of SCL.
