  • The general and some pharmacological actions of DWP 302 were investigated in animals and the following results were obtained. In central nervous system, DWP 302 had no effects on the pentobarbital induced anaesthesia, locomotor activity, rotarod test, traction test, analgesic action in the mice and body temperature in the rat. DWP 302 showed no depressive action on the convulsion induced by strychnine and electronic shock. From these results, DWP 302 was considered to have no or little pharmacological effect on the central nervous system. Furthermore, DWP 302 had no influences on the normal blood pressure and heart rate. In the isolated ileum of guinea pig, DWP 302 showed neither contractive nor relaxing effects against the acetylcholine ($10^{-6}g/mι$), histamine ($10^{-6}g/mι$) and $BaCl_2$ ($10^{-4}g/mι$) at a concentration of $1.9{\times}10^{-4}g/mι$ in bath. But it caused a slight increase in basal tone at a concentration of $6.3{\times}10^{-4}g/mι$ and this effect was inhibited by atropine $10^{-7}g/mι.$ In the isolated trachea and vas deference, DWP 302 showed no effect on the contractions produced by histamine and norepinephrine, respectively. And DWP 302 showed no effect on the contractions produced by acetylcholine and oxytocin in the isolated nonpregnant rat uterus. DWP 302 had no effect on bile excretion, urine volume, pH and gastrointestinal motility, But, DWP 302 showed a significant inhibitory effect on gastric secretion in the rat.

  • Results of an experiment on the general behavior of rats in order to explore the possible pharmacological actions of Panax Ginseng upon the central nervous system can be summarized as follows: 1) The rats treated with Ginseng-saponin intraperitoneally with the doses of 50 or 100 mg/kg show the decreased sleeping component and increase in lying and grooming component and walking and rearing component of general behavior. 2) There are no difference between control group and saline treated group in pattern of general behavior components. 3) In the Ginseng-saponin treated groups, the amphetamine stimulated walking and rearing component of genenarl behavior are reduced but lying and grooming component are elevated. 4) Ginseng-saponin shows very low acute toxicity in mice. The $LD_{50}$ in mice of 24 hours after intraperitoneal injection was 795 mg/kg. From the above findings, it is to suggest that the Ginseng saponin might stimulate the central nervous system but its mode of action appears to be different from that of amphetamine. And the effects of Ginseng saponin may be varied depending on various experimental situation or condition of animals.

  • The general pharmacological properties of new platinum (II) coordination complexes, SA : [Pt(trans-ι-DACH)(DPPE)] . 2NO$_3$, SB : [Pt(cia-DACH)(DPPP)] 2NO$_3$ and SC : [Pt(cia-DACH)(DPPE)] 2NO$_3$on central nervous, respiratory, cardiovascular and digestive systems were studied in various experimental animals. These platinum (II) anticancer agents had no effects on analgesia, thiopental-induced sleeping time, body temperature, strychnine-induced convulsion, inflammation and local anesthetic action in mice and rats. Intestinal motility, stomach-ulcer induced by serotonin and bile-secretion of rats were not influenced by the dose of 30 mg/kg. However SB and SC induced a mild decrease in heart rate in anesthetized rats. Based on these results, these new platinum (II) complexes may be regarded as a valuable lead compound in the development of new anticancer chemotherapeutic agents with marked antitumor activity and low toxicity.
