  • In order to investigate the pharmacologic properties of New Wonbang Woohwangchungsimwon Pill(NSCH), effects of Wonbang Woohwangchungsimwon Pill (SCH) and NSCH were compared using various experimental models. In rat aorta, NSCH and SCH made the relaxation of blood vessels in maximum contractile response to phenylephrine (10-6 M) regardless to endothelium containing or denuded rings of the rat aorta. Furthermore, the presence of the inhibitors of NO synthase and guanylate cyclase did not affect significantly the relaxing effects of NSCH and SCH. NSCH and SCH inhibited the vascular contractions induced by acetylcholine, prostaglandin endoperoxide or peroxide in a dose-dependent manner. In conscious spontaneously hypertensive rats (SHRs), NSCH and SCH decreased significantly heart rate. These, at high doses, had a negative inotropic effects that was a decrease of left ventricular developed pressure and (-dp/dt)/(+dp/dt) in the isolated perfused rat hearts, and also decreased the contractile force and heart rate in the isolated rat right atria. In guinea-pig papillary muscle, these had no effects on parameters of action potential such as action potential amplitude (APA), $V_{max}$ and resting membrane potential (RMP) at low doses, whereas inhibitory the cardiac contractility at high doses. Furthermore, these had a significant inhibitory effects on palpitation of the heart in normotensive rats and SHRs. These had a significant inhibitory effects on palpitation of the heart in normotensive rats and SHRs. These results suggest that NSCH and SCH have weak cardiovascular effects, and that there is no significant differences between cardiovascular effects of two preparations.

  • The purpose of this study was to prepare the granule using protein-bound polysaccharide isolated from Agaricus blazei Murill. Moisture content was the highest in granule formed with dextrin(DE=9). Sugar content of granule in relation to the forming agent was the highest in granule formed with ${\beta}$-cyclodextrin. pH and protein content were not affected by the forming agent. L and b values were high in granules formed with dextrin(DE=9) and ${\beta}$-cyclodextrin, respectively. Solubility of granule formed with dextrin(DE=23) and ${\beta}$-cyclodextrin was higher than that of formed with dextrin(DE=9), while there was no significant difference between dextrin(DE=23) and ${\beta}$-cyclodextrin. Rate of water absorption was the highest in granule formed with ${\beta}$-cyclodextrin, while the lowest in granule formed with dextrin(DE=9). Overall acceptance of three granules were acceptable in granule formed with ${\beta}$-cyclodextrin.

  • The value of Korean ginseng has been known in the world since the 4th century B. C. Red ginseng is hot-steamed, and then dried for the purpose of long-term storing. Through the steaming and drying process, its moisture rate is reduced to 14% and its color becomes citrine or light yellowish brown. Its hardened structure enables long-term storage without any deformation. Especially, Korean red ginseng contains substances that promote micro-physiological activities which are not found in American or Sanchi ginseng. Ginseng is produced in diverse forms for the customer's convenience. In this study, these are classified as sliced, dried, and honeyed ginseng, granulated tea, extract, powder, capsules, tablets, drinks and candy. Package design is one of the most effective method in the marketing fields. However, in this research, we found that red ginseng packages are not variously and properly developed in materials and designs. The research pointed out the problems and discuss ways and means of the package design.

  • The seasonal occurrence of aphids was investigated in the soybean Held to increase the control efficiency of aphid vectors of Soybean Mosaic Virus. The patterns of aphids occurrence were different according to planting time. There were two peaks in late June and mid-August in aphid population in optimum seeding (May 20), whereas the peak was around mid-June in early seeding(Apr, 20). Acyrthosiphon solani was dominant Species in early seeding, while Aphis glycines was dominant in optimum seeding. In early seeding, SMV incidence increased rapidly between 20 June and 30 June, suggesting that virus spread was strongly correlated with increased colonization of aphids. Imidacloprid WP, benfuracarb EC and acephate WP showed a good effect for the control of aphids without phytotoxicity. In the plot with infurrow treatment of imidachloprid G until 52 days after shooting, aphids were controled effectively. Acephate WP was applied as a foliar spray at V4, V6, or V4/V6 stage and all the treatments were effective on reducing: SMV incidence.

  • Hot water extracts of 5 herbs were tested in-vitro for anti-bacterial, anti-fungal, anti-parasitical effects for possible use against fish diseases. Skullcap, Scutellaria baicalensis, was the most effective herb in these 5. The effects of skullcap in cultured flounder were examined for various physiological responses and bacterial disease-prevention follow as feeding skullcap absorbed diet for 4, 8, 12weeks. There were not any significant effects in physiological responses, except beneficial action of growth promotion. No definitive preventive activity was observed with experimental feeding of the extract against infected flounder. As we could not confirm in-vivo antibacterial effects of skullcap in flounder despite its in-vitro efficacy, further studies are needed to define the in-vivo efficacy.

  • To investigate viral pathogenesis and in vivo efficacy of acyclovir (ACV) in mouse HSV-1 encephalitis models, female BALB/c mice aged 5 weeks were inoculated with strain F either intranasally (IN) or intracerebrally (IC). ACV-treatment by intraperitomeal injection with 0, 5, 10 and 25 mg/kg b.i.d. for 6 days was commenced 1 h after infection. Body weight and signs of clinical disease were noted daily up to 2 weeks. $ED_{50}$ of ACV in IN infection was <5 mg/kg and 14.1 mg/kg in IC infection. Tissues of central nervous system were collected from 2 mice per group everyday up to 5 day p.i. and the virus titers were measured. In IN infection model, high titers in eyes and trigeminal nerves were observed. ACV-treatment showed significant reduction of the titers in all the isolated. In IC infection model, cerebrum, cerebellum and brain stem showed high virus titers. ACV-treatment showed less significant reduction of virus titers than that in IN infection model. Reactivation of explanted trigeminal nerves from mice 30 day p.i. was monitored. In all of ACV treated mice reactivation was observed, i.e. even the highest dose of ACV did not inhibit the establishment of viral latency.

  • To investigate the effect of 'Saengkankunbi-Tang' on the liver tissue recovery in about 70% cutted rat liver, the observation on the photographing by the Gamma-camera and the electromicroscopic section against the rabbit liver induced by $CCl_4$, these studies were conducted. The results were summarized as follows; Observed on the liver tissue recovery, function regeneration and body weight increase in about 70% cutted rat liver, the recovery of liver tissue and body weight were increased with the passage of the time and also they were showed to the high increase rate in proportion to administration amount. The glucose content in the serum was found in increasing tide as compared with the control group. The alkaline phosphate activity in the serum showed the significant difference in the 10th day and 13th day as compared with the control group. The ammonia content in the blood showed the significant difference only in the 10th day. Observed on the photographing by the Gamma-camera against the rabbit liver induced by $CCl_4$, sample groups were shown to be significant recovery as compared with the control group. Observed on the electromicroscopic section, sample groups showed the control action of the nuclear destruction against the rabbit liver induced by $CCl_4$ and also they showed the control action of the expansion of glycogen and granular endothelial reticulum in cytoplasm. According to the above finding, it is presume that 'Saengkankunbi-Tang' can be applicable to the extensive treatment of liver disease.

  • The combined preparations of the traditional Korean prescriptions, Sahyangsohap-won (A1) and Woohwangporyong-hwan (B1) were evaluated on pharmacological actions in rats and mice, in parallel with the preparations of their modified prescriptions (A2 and B2). The acute toxicities of the four preparations were very low of which $LD_{50}$ values were more than 4g/kg, p.o. and no systematic symptoms were found at the doses. All the preparations showed sedative action by prolongation of sleeping time induced with hexobarbital sodium. The action was more potent in the modified preparations than in the original ones. All the preparations had no anticonvulsant action both in chemoshock seizures induced by pentetrazole and strychnine and in electroshock seizure. In rat fundus preparation, A1 and A2 elicited strong contraction at the concentration of $1{\times}10^{-3}\;g/ml$ in bath, whereas B1 and B2 did neither contraction nor relaxation at the same concentration. The four preparations had no inhibitory effect against acetylcholine induced spasm. In rat intestinal preparation, the four preparations exhibited neither contraction nor relaxation. However, A1 and A2 had antagonistic effect against spasm at the concentration of $1{\times}10^{-3}\;g/ml$. Single administration of each preparation at the dose of 0.24g/kg, p.o. stimulated the secretion of pepsin in rat stomach without inciting the secretion of gastric juice. Their stimulating actions were more marked in B1 and B2 than in A1 and A2, and were more promptly exhibited in the modified preparations (A2 and B2). Accelerating action of bile secretion by single administration of each preparation was found at the dose of 0.24g/kg, p.o. in rats. All the preparations except A2 also stimulated the secretion of bile acid.

  • The water dispersible granule flupoxam showed over 95% of weeding effect on the annual weeds of Poaceae such as Poa annua L., Digitaria ciliaris (Rets.) Koel and broad-leaf weeds. Efficacy of treatment had been lasted over 120 days in the $2kg\;ha^{-1}$ when it was treated from March to April while lasted over 180 days when it was treated from September to October. Because the flupoxam has a high soil absorptivity, a perfected herbicide layer is formed. This results in perfect weeding effect regardless of the presence or absence of thatch. Because the flupoxam has a different mechanism of action from the conventional herbicides such as dinitroanilines, pyridines, and carbamates, it is very effective with the alternative spray. Phytotoxicity symptoms was not observed and/or produced antocyan in new leaves in the landscape trees around the lawngrass by flupoxam treatment.
