In the previous report it was demonstrated that aqueous extracts of two Korean indigenous crude drugs, Radix Jingyu and Fructus ponciri, have an excellent tick repellent effect, and also the need for further analytical study of these crude drugs was suggested. In the experiments to be reported herein, attempts were made to find out the active ingredients from Radix Jingyu, since the aqueons extract of Radix Jingyu proved to be mone effective than that of Fructus ponciri. It will be shown that the active ingredient is indicative of Lycaconitine, a known alkaloid. An aqueons solution containing 1.5 Gms of Lycaconitine in tartrate when sprayed on a cow exerted tick repellent effect against Boophilus microplus which lasted approximately 25 days without any harmful influences on cattle. It will also be shown that the oil-fat components of Radix Jingyu act synergistically with Lycaconitine in accelerating and lengthening the effect, although the components alone have no effect under the conditions tested. It was of interest to note that the oil-fat components of Radix Jingyu showed definite repellent effect against the larvae of Boophilus microplus in laboratory experiments by the method newly devised. On the basis of these observations, it was concluded that Lycaconitine can be used as cattle tick repellent, and the evidence seems to warrant a large scale production of Lycaconitine for its widespread use. Further studies on the possible effect of the alkaloid on other genera or species of ticks and related vermins were also indicated.

Objectives : To identify the active ingredient of Poncirus Trifoliata Immaturus and to explore the mechanism expected to potentially act on dermatitis accompanied by pruritus. Methods : We conducted the network pharmacological analysis. We selected effective ingredients among the active compounds of Poinciri Fructus Immaturus. We found the target protein of the selected active ingredient, disease(dermatitis accompanied by pruritus) and fexofenadine. Then we established the network between the proteins which Poinciri Fructus Immaturus and fexofenadine intersected with disease respectively, and the coregene was also extracted. After that, the active pathways in the human body involving the groups and coregenes were searched. Results : Total of 7 active ingredients were selected, and 202 target proteins were collected. There were 756 proteins related to inflammatory skin disease accompanied by pruritus, and 75 proteins were related to fexofenadine. 42 proteins crossed by Poinciri Fructus Immaturus with a disease, and 31 proteins crossed by fexofenadine with a disease. 12 proteins were found as a coregene from the proteins that cross Poinciri Fructus Immaturus and disease. Coregenes are involved in 'Nitric-oxide synthase regulator activity', 'Epidermal growth factor receptor signaling pathway'. 2 groups that extracted are invloved in 'Fc receptor signaling pathway', 'Central carbon metabolism in cancer', 'Phosphatidylinositol 3-kinase complex, class IB', and 'omega-hydroxylase P450 pathway'. Conclusion : It is expected that Poinciri Fructus Immaturus will be able to show direct or indirect anti-pruritus and anti-inflammatory effects on skin inflammation accompanied by pruritus in the future. And it is also expected to have a synergy effect with fexofenadine on skin disease.

To certify the protective effect of herbal medicine against oxygen free radical-induced myocardiotoxicity, cytotoxicity was measured using LDH activity and TBARS assay in the presence of Jisilhaebaekgyejitang(JHGT) extracts or single constituents of this prescription, In the present study, xanthine oxidase/hypoxanthine (XO/HX) resulted in a cell damage such as increases in LDH activity in culture medium and lipid peroxidation in cultured myocardial cells. In the effect of JHGT extract and its single constituents, which are Fructus Ponciri Seu Aurantii Immaturus (FPSAI), Cortex Magnoliae Officinalis (CMO), Bulbus Allii Macrostemi (BAM), Ramulus Cinnamomi (RC) and Fructus Trichosanthis (FT), they showed the prevention from the XO/HX-induced cardiotoxicity by the decrease of LDH activity and lipid peroxidation. From these results, they show that XO/HX is cardiotoxic in cultured myocardial cells derived from neonatal rat, and it suggests that JHGT, FPSAI, PT, CMO, BAM, RC and FT extracts are positively effective in the blocking in XO/HX-induced cardiotoxicity.

During the screening for inhibitors on nitric oxide (NO) production in LPS-activated murine macrophage, RAW 264.7 cells, two coumarins were isolated from chloroform extract of Ponciri Fructus. They were identified as imperatorin (10), phellopterin (11) on the basis of spectroscopic methods. The $IC_{50}$ values for NO formatiom were about $5.4\;{\um}M$ and $35.0\;{\um}M$, respectively, and then eleven coumarins were tested for the inhibitory effects on NO production in activated macrophages. All the test coumarins inhibited NO production in concentration-dependent manner and furanocoumarins (6-11) showed much more potent inhibitory effect than simple coumarins. Among the compounds examined xanthotoxin (8) was the most potent inhibitors of NO production $(IC_{50}=1.4\;{\mu}M)$. Analysis of the structure-activity relationship among these coumarins led to the conclusion that the substitution of C-5 position in furanocoumarins reduces greatly their inhibitory potency although the substitution of C-8 does not almost affect it.

Natural Killer cells are considerd to play an important role in antitumor immune surveilance mechanism. In this study, 21 putative anticancer drugs selected from reference were assessed by evaluating the effect on rat Natural Killer cell activity (NKCA). All 21 herb drugs were extracted in boiling water, lyophilized, autoclaved, and then used for experiment. Culture supernatant of concanavalin-A (Con-A)-stimulated rat spleen cells as a source of lymphokine was also used as a control of comparison. Rat spleen cells were used as effector and NKCA was measured in 4hr $^{51}Cr-release$ assay against Yac-1 mouse lymphoma cell line. In order to determine the optimal conditions for NKCA augmentation, effector cells were treated with 3 different concentrations of each drug for 24, or 48 hrs before testing of NKCA, In optimal conditions determined from previous results, the effect of herb drugs on NKCA were assessed in 3 to 5experiments. NKCA was significantly enhanced by treatment with 4 herb drugs(Ponciri Fructus, Houttuyniae Herba, Aurantii Pericarpium, Nepetae Herba). Culture supernatant of Con-A-stimulated spleen cells also augmented the rat NKCA more significantly. The results show that 4 of the herb medicines supposed to display anticancer effect may have activity as a biological response modifier through augmentation of NKCA.

Poncirus Fructus (PF) is obtained by drying the trifoliate orange fruit belonging to the Rutaceae family. In our country of medicine, PF has been used as a treatment of indigestion, allergy and inflammation. But Mechanism and medical data for PF is insignificant. Recently, the effect of the study PF of biological activity was reported, such as anti- thrombosis, anti-bacteria, anti-virus, anti- allergic. We investigated that the effect of PF on anti-inflammatory in murine macrophage-like cell line Raw264.7 cells. Our results show that the expression level of Nitric Oxide (NO) and Matrix-metallopeptidase-9 (MMP-9) significantly decreased. Moreover, to determine the expression level of pro-inflammatory cytokines such as Tumor Necrosis Factor ($TNF-{\alpha}$) and Interleukin-6 (IL-6) and the phosphorylation pattern of signaling molecules of mitogen-activated protein kinase (MAPK) family, we performed ELISA and westren blot in Raw264.7 cells. In addition, nuclear factor-kappa B ($NF-{\kappa}B$) pathway was confirmed. PF extract inhibited the production of $TNF-{\alpha}$ and IL-6. The extract suppressed the phosphorylation of ERK1/2, JNK, and p38 MAPK, and the nuclear translocation of $NF-{\kappa}B$ p65 in activated cells. Our results suggest that PF can be used as a potential therapeutic agent or functional food to relieve inflammation.

Objectives: This study aims to review the herbal medicines containing substances banned by World Anti-Doping Agency(WADA), and to consider criteria for the using of herbal medicines. Methods: Using foreign(Pubmed, Cochrane, Embase, Google Scholar, WANFANG, CiNii) and domestic databases (NDSL, OASIS, RISS), we analyzed the content and pharmacokinetics of the prohibited substances in herbal medicines. Results: Herbal medicines containing the prohibited substances proposed in Korea, China, and Japan are Ephedrae Herba, Cannabis Semen, Strychni Semen, Strychni Ignatii Semen, Pinelliae Tuber, Rhizoma Pinelliae, Chelidonii Herba, Papaveris Fructus Deseminatus, Liriopis Tuber, Rehmanniae Radix Recens, Cistanchis Herba, Ponciri Fructus Immaturus, Aurantii Fructus Immaturus, Moschus, Testudinis Plastrum, Otariae Testis et Penis, and Hominis Placenta. Of these, when using Ephedrae Herba, Cannabis Semen, Strychni Semen, Moschus, Strychni Ignatii Semen, and Otariae Testis et Penis, caution is needed in relation to the doping test. Other herbal medicines are considered safe for the doping test. In addition, by analyzing data related to higenamine added to the WADA's prohibited list of doping since 2017, we don't recommend using Nelumbinis Plumula. And in the case of the other herbal medicines containing higenamine, it is considered that care should be taken in doping test depending on the amount of usage. Conclusions: As a result of analyzing the herbal medicines which are in prohibited list about doping, we were able to know the criteria and precautions to use when prescribing the herbal medicines. Further research will be needed about common used herbal medicines and the amount of detection depending on extraction and boiling method.

In vitro sensitivity testing was performed for 21 kinds putative anticancer drugs selected from references and information. Cellular damage of P815 mastocytoma cells following exposure to water extracts of drugs was evaluated by colony formation assay. Highly effective drugs with more than 50% inhibition of colony formation were seven (Houttuyniae Herba, Sanguisorbae Radix, Nepetae Herba, Manitis Squama, Lonicerae Flos, Amomi Semen, Polyporus), though not more effective than BCNU. According to the results of $^3H-thymidine$ incorporation assay for determination of selective cytotoxicity, 3 of these drugs (Houttuyniae Herba, Polyporus, Manitis Squama) were found to be low cytotoxic to normal mouse lymphoid cells. These findings suggest that the above 3 drugs may be used for effective anticancer drugs in vivo.
