  • The acute and subacute toxicities and pharmacological actions of two preparations of Ssanghwa Tang prescriptions have been evaluated in mice, rats and rabbits. The two prescriptions were found to be safe drugs because those preparations exhibited almost no acute and subacute toxicities even at a high dosage level. The two prescriptions elicited CNS depressant activities characterized by potentiation of hexobarbital-induced narcosis, antipyretic activity in typhoid-vaccinated rabbits and a significant antifatigue effect against cold immobilized stress, the activities of prescription B being more potent.

  • The pet ether extract of Caesalpinia pulcherrima, leaves was studied for its antinociceptive, anti-inflammatory and antipyretic property. The extract at doses of 50 and 200 mg/kg, p.o., significantly (p<0.05) reduced the number of writhing induced by acetic acid and inhibited the late phase (20-30 min) in formalin test in mice. The extract failed to increase the pain threshold level in tail immersion test in mice. In carrageenan induced paw edema in rats and in acetic acid induced increase in vascular permeability test in mice, the extract (50-600 mg/kg, p.o.) failed to produce any significant activity. While in cotton pellet granuloma test, the extract at doses of 200 and 600 mg/kg (p.o.) significantly (p<0.05) reduced the granuloma formation and was comparable to reference drug, dexamethasone. In ethylpheylpropiolate ear edema test 0.5 mg and 1 mg/ear application of extract significantly (p<0.05) inhibited ear edema. In yeast induced hyperthermia in rats, the extract did not produce any reduction in temperature. The results suggest that the extract acts peripherally to produce analgesic action and anti-inflammatory activity through steroidal mechanism.

  • Effective BuOH fraction was extracted from Puerariae radix (Pueraria thunbergiana), and several pharmacological activities were examined. From several pharmacological examinations, it was found that BuOH fraction has an antipyretic activity against typhoid vaccine pyrexia in rabbit, a papaverine-like antispasmodic activity on isolated ileum and jejunum of rat, an analgesic effects on mice treated by 0.7% HAc, and an anti-inflammatory activity of carrageenin edema in rat. It was found that BuOH fraction has detoxication effects on acute and subacute toxic rat induced by alcohol in consequence of biochemical tests of serum. Therefore it was considered that BuOH fraction has preventive and therapeutic effects in alcohol intoxication.

  • Antibiotic activity and antipyretic effect of three synthetic prodrugs, chloramphenicol acetylsalicylate (CAF-ASP), chloramphenicol naproxenate(CAF-NAX) and chloramphenicol acetaminophen succinate (CAF-SUC-ACET), were studied in vitro and in vivo. In the experimental results, the CAF-NAX showed the moat rapid absorption and the highest blood levels, and the CAF-SUC-ACET and CAF-ASP also were more rapid absorption and higher blood levels than controls, chloramphenicol and chloramphenicol palmitate. The synthetic prodrugs also showed the antipyretic effect by modified Roszkowski method using endotoxin.

  • Chloramphenicol (CAF) was esterified with aspirin, naproxen and acetaminophen in order to develop new prodrugs which have double effect-antibiotic activity and antipyretic effect. Chloramphenicol acetylsalicylate (CAF-ASP), chloramphenicol naproxenate (CAF-NAX), and chloramphenicol acetaminophen succinate (CAF-SUC-ACET) were synthesized by using dicyclohoxylcarbodiimidc (D.C.C.) because of two hydroxyl group of chloramphenicol. Three synthetic prodrugs did not show bitterness and antibiotic activity in vitro, and were hydrolyzed in liver homogenate, but weren't in acid.

  • In order to obtain acetaminophen, a popular analgesic-antipyretic, though microbial p-hydroxylation and N-acetylation of aniline, various Streptomyces strains were screened. Aniline N-acetylation activity was rather ubiquitous but-hydroxylation activity was selective. Microbial conversion pathway of aniline to acetaminophen was considered to be through N-acetylation and p-hydroxylation or vice versa. However, depending on species used, o-hydroxylation and its degradation activity (S. fradiae) and acetaminophen degradation activity (S. coelicolar) were also detected. Among the screened Streptomyces strains, S fradiae NRRL 2702 showed the highest acetanilide p-hydroxylation activity (203% conversion rate). Furthermore, in S. fradiae carbon source and its concentration, phosphate ion concentration and pH of growth medium were found to play the crucial roles in p-hydroxylation activity. Through the proper combination of factors mentioned above, the ten times more activity (26-30% conversion rate) was attained.

  • Objectives : Modified Gamgil-tang is a prescription commonly used for respiratory diseases. This thesis was carried out to check the treatment effects and diversity of drug formulation by comparing extraction method of ethanol and water of modified Gamgil-tang. Methods : All experiments were carried out with water and 50% ethanol extraction for comparison. In vivo experiment, hyaluronidase inhibitory effects and trypsin inhibitory effects were tested to measure the anti-inflammatory effects activity. Scavenging effects of DPPH free radical, xanthine oxidase inhibitory effects and inhibition on TBA-RS formation were experimented to measure anti-oxidative effects. With the in vivo experiment, ICR group mice and SD group rats were used as experimental animals. An anti-inflammatory effects experiment were carried out to measure the action on carrageenin-induced hind paw edema: analgesic effects were measured using writhing syndrome induced by 0.7% acetic acid in mice: antipyretic effect was measured using endotoxin, and inhibitory effects of increase vascular permeability induced by 0.5% histamine were measured. Results : For extraction of glycyrrhizin contents, ethanol extract was extracted 2 times of that of water extract. Anti-inflammatory effects showed high in ethanol extract. Anti-oxidative effects measured high in ethanol extract. No significant result was found in inhibition on TBA-RS formation. Analgesic effects were found to be similar in water and ethanol extract. Antipyretic effects were found to be stronger in water extract. Inhibitory effects of increase vascular permeability induced by 0.5% histamine showed stronger in ethanol extract. Conclusion : By measuring anti-inflammatory effects, analgesic effects, antipyretic effects, anti-oxidative effects, and histamine permeation inhibition effects both in water extract and ethanol extract after adding agents such as Mentha Herba, Gardenias Fructus, and propolis to existing Gamgil-Tang, ethanol extract was found to be more effective in anti-inflammatory effects, analgesic effects, anti-oxidative effects, and histamine permeation inhibition effects. The converse was found for antipyretic effect.
