  • Attempts were to investigate the effects of 'Bojungikgi-tang' on the digestive system, blood pressure and diuresis. The results showed that relaxing action was shown on the isolated ileum in mice and that strong antagonistic actions were seen on $BaCl_2$, acetylcholine and histamine-induced contraction of the ileum in mice and guinea-pigs that the relaxing effect of the intestinal smooth muscle was recognized. Inhibitory effects on transport rate in the small intestine of mice and castor oil-induced catharsis in mice were noted. Inhibitory action on the secretion of gastric juice, pH ascending effect and decreasing effect of the free acidity and total acidity were recognized. Continuous hypotensive action was seen, but when the vagus nerve was cut, hypotensive action was remarkably decreased. The diuretic effect was also recognized.

The results of this investigation were summarized as follows; Analgesic action by the acetic acid stimulating method in mice were recognized. Prolonging action against the hypnotic duration induced by thiopental-Na was noted in mice. Antipyretic effect in typhoid vaccine febrile rats was recognized. Spontaneous motility of the isolated ileum of mice was suppressed and contractions of the isolated ileum of mice and guinea-pig induced by accetylcholine chloride, barium chloride and histamine were remarkably inhibited. Vaso-diating and hypotensive actions were recognized in rabbits. GOT and GPT activities in the serum of rats damaged by $CCl_4$ and galactosamine were decreased remarkably.

  • The general pharmacological properties of EPO were investigated in various animals administering intravenously and in vitro system. The results were as follows. 1. Central nervous system: EPO at doses of 70, 700, 7000 U/kg showed no effect In mice on general behavior, on strychnine- and pentetrazol-induced convulsion and on acetic acid-induced writhing syndrome. The hexobarbital-induced sleeping time in mice was slightly reduced by EPO at a dose of 7000 U/kg but did not change at doses of 70, 700 U/kg. The body temperature in rats was slightly decreased by EPO at doses of 700, 7,000 U/kg but the change was in normal physiological range. 2. Respiratory and cardiovascular system: EPO showed no effect on respiratory rate, blood pressure, heart rate, femoral blood flow, and electrocardiogram in anesthetized dogs at doses of 70, 700, 7000 U/kg. 3. Smooth muscle: EPO at concentrations of 70, 700 U/ml had no effect on the contractile response of isolated guinea pig ileum to histamine and acetylcholine. 4. Water and electrolytes excretion: EPO at dose above 700 U/kg increased urine volume in rats but did not affect the concentrations of $Na^{+},\;K^{+},\;Cl^{-}$ in urine. 5. Gastrointestinal system: EPO(70, 700, 7000 U/kg) had no effect on the intestinal charcoal meal propulsion 6. Blood coagulation system: The administration of EPO(70, 700, 7000 U/kg) had no effect on the plasma prothrombin time(PT) and activated partial thromboplastin time(APTT) in mice. Platelet aggregation induced by ADP and collagen was not influenced by EPO(70 U/ml, 700 U/ml). The overall results obtained indicated that EPO exerts almost no serious pharmacological effect even at a 100-fold clinical dose(7000 U/kg).

  • General pharmacological properties of ι-muscone, the major component of musk, were investigatedin mice, rats and guinea pig. The administration of ι-muscone (1, 10, 100 mg/kg, p.o.) in mice had no effects in general behaviors, and no influences on analgesic actions and normal body temperature. Muscle relaxant action, intestinal propulsion and gastric secretion were not observed even at the high dose of 100 mg/kg. ι-Muscone (1, 10, 100 mg/kg, p.o.) given to conscious rats showed no effect on mean blood pressure and heart rate. It showed no direct effect at 2.4$\times$10.3 mg/ml and 2.4$\times$10-2 mg/ml in isolated uterus of rats and ileum of guinea pig, and also had no inhibition of contraction induced by oxytocin and histamine.

  • Aspalatone [3-(2-methyl-4proponyl)]-2-acetyloxybenzoate, CAS 147249-33-0) is a compound having an antithrombotic action. General pharmacological properties of aspalatone were studied. Aspalatone had no effect on central nervous system and no anticonvulsant effect up to 1200 mg/kg p.o. However, the compound has hypothermic and analgesic effect. When administered intravenously in rabbits, aspalatone did not affect blood pressure, heat rate and respiration rate and depth, and it did not inhibit transient hypotensive effect of acetylcholine. The compound did not affect isolated guinea-pig ileum and tracheal strip at a concentration of 1${\times}$$10^{-4}$, and did not inhibit histamine-induced contraction of guinea-pig ileum. It also did not affect isolated rat stomach fundus and estrogenated rat uterus at 1${\times}$$10^{-4}$, and did not inhibit contraction produced by acetylcholine or oxytocin. The pupil size and intestinal propulsion were not influenced at a large dose of was shown. The compound showed a slight increase in urine volume and led to decreased excretion of potassium in urine of rats. The results suggest that aspalatone may have no considerable adverse effects in general pharmacological aspect.

  • The effects of cimetidine or ranitidine pretreatment on the intestinal absorption, plasma and urine level of caffeine, gastric acidity of mouse, and sleeping time by hexobarbital sodium were investigated pharmacokinetically. Cimetidine and ranitidine pretreatments were found to increase both the rate and extent of absorption of caffeine in rats. Cimetidine pretreatment increased blood level of caffeine and decreased urine level, while ranitidine pretreatment had no effect on urine level of caffeine. Ranitidine pretreatment inhibited gastric secretion due to caffeine more than cimetidine pretreatment. Cimetidine pretreatment increased the action of caffeine and showed shorter sleeping time by hexobarbital sodium, comparing with ranitidine pretreatment.

  • Seungmagalgeuntang-gamibang has long been known to have anti-allergic effect. However, the mechanism of action of Seungmagalgeuntang-gamibang is not well investigated. The author analysed the effects of Seungmagalgeuntang-gamibang on the vascular permeability, delayed-type and contact hypersensitivities, and phagocytic function, the results obtained are as follows: 1. Administration of Seungmagalgeungtang-gamibang decreased the vascular permeability induced by serotonin in the mouse. 2. Administration of Seungmagalgeuntang-gamibang decreased the vascular permeability induced by histamine without statistical significant. 3. Administration of Seungmagalgeuntang-gamibang decreased the delayed-type hypersensitivity induced by sheep red blood cells. 4. Administration of Seungmagalgeungtang-gamibang decreased the contact hypersensitivity induced by dinitrochlorobenzene. 5. Seungmagalgeungtang-gamibang increased the phagocytic-activities of macrophages in vitro and in vivo. 6. Seungmagalgeungtang-gamibang enhanced the formation of reactive oxygen intermediates in vitro and in vivo. The above results demonstrate that Seungmagalgeuntang-gamibang suppresses the hypersensitivity reactions with increasing the phagocytic functions and formations of reactive oxygen intermediates from macrophages.

  • Economic animal husbandry workers exposed to organic dust can be suffered from immunologic disorders. Our study was to determine immunological parameters related with occurrence of respiratory allergic diseases to animal husbandry workers in Korea for the first time. Peripheral blood were obtained from twenty-five pig barn workers, forty-nine chicken farming workers and fifty-one non-agricultural control workers. Significantly upregulated plasma IgE level was observed with pig-barn workers than that of chicken farming workers or healthy community control subjects. Furthermore, level of histamine, a hallmark of allergy induction, was upregulated in the pig and chicken farming workers in comparison with that of the control subjects. Downregulation of $IFN_\gamma$ and $TNF_{\alpha}$ production from T cells was apparent in the animal husbandry workers compared with the control subjects. Meanwhile, T cells collected from the pig barn workers demonstrated significantly higher production of IL-4 and IL-10 than the other groups. There were also alterations in IgG subclass distribution. In conclusion, immunological modulation probably leading to occupational allergic diseases can be occurred in the economic animal husbandry workers and the pig barn workers could be the most risky group to the work-related allergic disease.
