  • Objectives: Genital herpes is common disease in gynecological field. Although various treatment options such as herbal medicine, acupuncture, moxibustion are used in genital herpes, there is not enough evidence about the treatment options. This study is to prove the efficacy of oriental medicine on genital herpes by investigating papers and suggest direction of future research. Method: We searched for papers which had both genital herpes and oriental medicine from Cochrane, Pubmed, Scopus, CNKI, Oasis, Korean traditional knowledge portal, Journal of Korean Obstetrics & Gynecology up to November 2017. After searching papers, we classified according to the study design and analyzed selected studies. Results: Sixteen papers were finally selected. Four papers are laboratory studies with Hartley guinea pig with recurrent genital herpes. Twelve papers are clinical trials which includes one single group trial, one controlled trial, ten randomized controlled trials. All of the studies have shown that herbal medicine is effective in improving the symptom of genital herpes and decreasing the recurrent rate of genital herpes and also has immunoregulatory effect. Conclusions: This study shows that herbal medicine could be a good treatment option for genital herpes. However, more well-designed clinical studies and laboratory studies will be needed.

  • LB20304 is a novel fluoroquinolone that exhibits a potent broad spectrum antibacterial activity against both gram-positve and gram-negative bacteria. The MICs (Minimal Inhibitory Concentration) of LB20304 were determined against both gram-positve and gram-negative bacteria under various conditions including several media, pHs, and inoculum concentrations. The in vitro activity of LB20304 was not significantly affected by the changes in testing conditions such as components of media and inoculum concentrations, but it was slightly reduced by acid condition. The MICs and MBCs (Minimal Bactericidal Concentration) of LB20304 against Staphylococcus aureus, Escherichia coli and Pseudomonas aeruginosa were hardly affected by the presence of 50 % human serum, mouse serum, guinea pig serum or horse serum, and the MBCs were equal to or at most four-times higher than the MiCs. The activities of LB20304 were decreased by the presence of high concentraion of $Mg^{++}$ or human urine (pH, 5.5) in the test media. The frequencies of mutants resistant to LB20304 were similar to or lower than those found in ciprofloxacin and sparfloxacin.

  • Biflavonoid is one of unique classes of naturally-occurring bioflavonoids. Certain biflavonoids including amentoflavone were previously reported to have inhibitory effect on the group 11 phospholipase $A_2$ activity. Amentoflavone was also found to inhibit cyclooxygenase from guinea-pig epidermis without affecting lipoxygenase. In this study, anti-inflammatory and analgesic activities of amentoflavone were evaluated. When amentoflavone was administered intraperitoneally, it showed a potent anti-inflammatory activity as determined by amelioration of croton-oil induced mouse ear edema. It also showed a potent anti-inflammatory activity in the rat carrageenan paw edema model ($ED_{50}$=42 mg/kg) compared to the activity of prednisolone (35 mg/kg) and indomethacin (10 mg/kg). However, amentoflavone did not show a significant inhibitory activity against rat adjuvant-induced arthritis, a chronic inflammatory model. In addition, amentoflavone was found to possess a potent analgesic activity in the acetic acid writhing test ($ED_{50}$=9.6 mg/kg) compared to the activity of indomethacin (3.8 mg/kg). These results suggest that amentoflavone may be a potential lead for a new type of anti-inflammatory agents having dual inhibitory activity of group 11 phospholipase $A_2$ and cyclooxygenase.

  • Anemarrhenae Rhizoma has been clinically used as a sedative drug in oriental medicine. We observed the sedative action and effect on the movement of isolated-ileum with each water extract of Anemarrhenae Rhizoma (F-I), saline solution treated preparation (F-II) and 25% ethanol treated preparation (F-III). The results obtained were summerized as follows; 1) Sedative actions were recognized with F-I, F-II and F-III. 2) Prolonged effect of sleeping time was recognized significantly with F-I, F-II and F-III. 3) Each fraction of Anemarrhenae Rhizoma showed the released action on the isolated-ileum of the mouse, rat, rabbit and guinea pig, and antagonic action against contraction induced by acetylcholine, barium chloride and histamine. Thus the mechanism in the released action of the smooth muscle was partly considered as the direct dependence of the smooth muscle.

  • Hyangsayangwee-Tang, a combined preparation of crude drugs, which has been used for stomach and intestinal disorder, was examined for anti-spasmodic, anti-ulcerative and anti-emetive effects. Spontaneous motility of isolated ileum was strongly suppressed and inhibitory effects against contraction of isolated ileum induced by acetylcholine and barium chloride were shown in mice. And, contraction of isolated guinea-pig ileum by histamine was inhibited. In rats fundus preparations, Hyangsayangwee-Tang elicited strong relaxation and had antagonist effects against the spasm induced by acetylcholine and barium chloride. A significant inhibitory effect on the intestinal propulsion of barium sulfate in mice was shown. In pylorus-ligated rats, Hyangsangwee-Tang inhibited gastric secretion and showed a strong anti-peptic activity. Protective effects against gastric ulceration induced by pyloric ligation, water-immersion stress, histamine and aspirin were significantly recognized in mice and rats. Hyangsayangwee-Tang decreased cupric sulfate-induced vomitting in frogs.

  • In traditional medicines, Dansam-samul-tang and Samwhang-sasim-tang extracts were known to effects of antioxidant and antimicrobial activity. To investigate the safety evaluation of skin, these extracts were measured to skin safety testing such as primary skin irritation test, eye irritation test and skin sensitization test. The results of the primary skin irritation test and eye irritation test in vitro showed that these extracts included in the nonirritating area. Skin sensitization test results by Guinea Pig Maximization (GPMA) indicated that there was no allergy reaction. Therefore, Dansam-samul-tang and Samwhang-sasim-tang extracts were very safe in every safety test of skin. These results suggests that Dansam-samul-tang and Samwhang- sasim-tang extracts in 1 % concentration can be useful cosmetic ingredients.

  • This paper reviews the toxicological role of median lethal dose ($LD_50$) based on animal and human data. Animal oral $LD_50$ values of eighty seven chemicals were collected and comparatively evaluated with human minimum toxic dose ($TD_50$). In general, animal $LD_50$ values were much higher than human $TD_50$. The ratios between $LD_50$ and TDlo were ranged from 0.01 and over 1000, suggesting safety factor of up to 1000 between humans and animals in the case of acute toxicity data. However, about 40% of chemicals investigated were within the ratio of 10. Although the cases (N=20) were small, $LD_50$ values of guinea pig were closer to human TDlo than those of other animal species. In interanimal species (rat, mouse, rabbit, dog), the ratios of $LD_50$ values were between 0.1 and 5 (up to 50-fold difference). When the data are analyzed by chemical strut-ares, human $TD_50$ values were very close to rat oral $LD_50$ values. These data suggest that rat oral $LD_50$ value might be a useful parameter predicting human TDlo and one animal species could be sufficient for acute toxicity test.

  • General pharmacological properties of recombinant human parathyroid hormone (hPTH) were examined. The administration of hPTH (7, 35 and 175 lU/kg sc) in mice had no effects in general behavior and central nervous system, and no influences on normal body temperature, writhing syndromes induced by 0.7% acetic acid solution and chemoshock produced by strychnine and pentetrazol solution. hPTH (9 and 44 lU/kg, sc) given to anesthetized rabbits showed no effect on blood pressure of carotid artery and respiration, and it did not influence the responses produced by injection of acetylcholine or epinephrine. It showed no direct effect at 4.4$\times$10$_{-2}$IU/ml in isolated stomach fundus and uterus of rats and ileum of guinea-pig, and it also showed no inhibition of contraction produced by acetylcholine, oxytocin, serotonin and histamine in the above-mentioned preparations. It did not influence intestinal propulsion at the doses of 7,35 and 175 lU/kg sc in mice. This drug exhibited no effect on urinary excretion at the doses of 7 and 35 lU/kg sc in rats. However, at a dose of 175 lU/kg sc, it showed a decreased urination along with decreased excretion of potassium, sodium and chloride ion. These results indicate that hPTH does not exert any of serious pharmacological effects except the inhibition of urination at a highest dose used.

  • In order to investigate the pharmacological properties of New Wonbang Woohwangchungsimwon Liquid (NSCL), effects of Wonbang Woohwangchungsimwon Liquid (SCL) and NSCL were compared. In isolated rat aorta, NSCL and SCL showed the relaxation of blood vessels in maximum contractile response to phenylephrine (10$^{-6}$ M) regardless to intact endothelium or denuded rings of the rat aorta. Furthermore, the presences of the inhibitor of NO synthase and guanylate cyclase did not affect the relaxing effect of NSCL and SCL. NSCL and SCL inhibited the vascular contractions induced by acetylcholine, prostaglandin endoperoxide or peroxide in a dose-dependent manner. In conscious spontaneously hypertensive rats (SHRs), NSCL and SCL significantly decreased heart rate. NSCL and SCL, at high doses, had a negative inotropic effect 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 excised guinea-pig papillary muscle, NSCL and SCL had no effects on parameters of action potential such as resting membrane potential, action potential amplitude, APD$_{90}$ and V$_{max}$ at low doses, whereas inhibited the cardiac contractility at high doses. These results suggested that NSCL and SCL have weak cardiovascular effects with relaxation of blood vessels and decrease of heart rate, and that this effect is no significant differences between cardiovascular effects of two preparations.s.
