Benorylate and ethoxybenzamide have been used alone or in combination as an analgesic, antipyretic and antiinflammatory agent. We investigated the significance of the differences of analgesic activities between single and concurrent administration of benorylate and ethoxybenzamide and lorazepam in mice and also antipyretic activity between single and concurrent administration of benorylate and ethoxybenzamide in rats. 1). Concurrent administration of each half dose of benorylate and ethoxybenamide showed much inhibiting effect on the acetic acid-induced writhing syndrome of mice than the above drug alone, and the some increased analgesic response by hot plate method. 2). The synergistic and analgesic effect of combined administration of benorylate and lorazepam was found to be significant. 3). Antipyretic effect of half-dose combined administration of benorylate and ethoxybenzamide on the rat pyrexia induced by yeast(s.c.) and T.T.G. (i.v.) was shown to be similar to the effect of each drug.

The ethanol extracts of Opuntia ficus-indica fructus (EEOF) and Opuntia ficus-indica stem (EEOS) were prepared and used to evaluate the pharmacological effects of cactus. Both the extracts inhibited the writhing syndrome induced by acetic acid, indicating that they contains analgesic effect. The oral administrations of EEOF and EEOS suppressed carrageenan-induced rat paw edema and also showed potent inhibition in the leukocyte migration of CMC-pouch model in rats. Moreover, the extracts suppressed the release of $\beta$-glucuronidase, a lysosomal enzyme in rat neutrophils. It was also noted that the extracts showed the protective effect on gastric mucosal layers. From the results it is suggested that the cactus extracts contain anti-inflammatory action having protective effect against gastric lesions.

The Woo-Whang-po-Lyong-Whan has been used as one of the traditional medicines in the field of pediatrics so far since Song dynasty, and still it is widely being used nowadays. It might be considered to be a contribution to do further basic experimental studies on antipyretic, anticonvulsive and analgetic action of the Woo-Whang-po-Lyong-Whan. So it's pharmacological studies were carried out comparing to control drugs. ?Following conclusions were obtained. 1. It's antipyretic action was compared to that of aspirin by Writhing response using acetic acid-method. Mice were given one twentith, one tenth and one fifth tablets of the Woo-Whang-po-Lyong-Whan per Kg of body weight, respecitively. Writhing syndrome frequencies were noted as 38.4 in control group. and $18.0{\pm}12$, $13.17{\pm}2.28$, $7.33{\pm}12$ in above esperimental groups, respectively. In aspirin group it was $18.5{\pm}1.0$ when 2mg aspirin per body weight of mice was given. So it was recognized that antipyretic action of the Woo-Whang-Po-Lyong-Whan become remarkable by increasing amounts of the Woo-Whang-Po-Lyong-Whan. ?2. Antipyretic action in normal temperature mice group was not significant by increasing concentration of the Woo-Whang-Po-Lyong-Whan, but body temperature dropping in normal mice group was slightly noted than control. group, but less temperature dropping was noted than aminopyrin group. ?3. In fever provocated rats groups using Salmonella typhimurium, antipyretic action of the Woo-Whang-Po-Lyong-Whan was not observed significantly than control group. And slight antipyretic action was noted in aminopyrin group. So that antipyretic action of the Woo-Whang-Po-Lyong-Whan was not significant than those of general antipyretic used nowadays, but slower action was recognized. ?4. Anticonvulsive action of the Woo-Whang-Po-Lyong-Whan was studies comparing to that of phenobarbital. Action was not remarkable than phenobarbital, but was significant than control group. No significant intesifying action was noted by increasing amounts of the Woo-Whang-Po- Lyong-Whang.

CJ-50005 is a hepatitis A vaccine which is prepared by formalin inactivation of the HM175 virus cultured in human diploid MRC-5 cells. The general pharmacological properties of CJ-50005 were evaluated in various animals and in vitor system. CJ-50005 at the doses of 0.025, 0.25 and 0.75 $\mu\textrm{g}$/kg, i.m. had no effect on general behavior in mice, chemo- and electro-convulsions in mice, writhing syndrome induced by acetic acid in mice, the barbital sleeping time in mice, body temperature in rats, charcoal meal propulsion in mice and urine and electrolytes excretion in rats. In anesthetized dogs, CJ-50005(0.25 and 0.75 $\mu\textrm{g}$/kg, i.v) did not alter the respiratory rate, blood pressure, heart rate, femoral blood flow and ECG. In in vitro experiment, CJ-50005 at the concentration up to 0.02 $\mu\textrm{g}$/ml did not produce any changes in the contractions of the isolated ileum of guinea pigs caused by acetylcholine, histamine or $BaCl_2$. Since these pharmacological effects of CJ-50005 were observed at dose much greater than those in clinical use (approximately 0.025 $\mu\textrm{g}$/kg, i.m.), it is likely that this vaccine may be relatively free of undesirable effects in clinical practice.
