  • Purpose : Growth-promoting attempts are widespread in Korea, but little is known about their prevalence or associated factors. This study was designed to assess the prevalence of growth-promoting attempts among children visiting a university growth clinic. Methods : A questionnaire-based survey was carried out with 823 children (416 boys, 407 girls) who visited the growth clinic at Paik Hospital. Results : The mean age of the subjects was $10.4{\pm}2.6$ yr, and the height z-score was $-1.58{\pm}0.91$. Approximately 33.4% of the children had tried growth promotion. Among the height-gain methods, herbal medicine was the most frequently used (37.8%), followed by health-promoting supplements (37.1%), exercise or machine (3.0%), and growth hormone treatment (2.9 %). The mean age at which the parents began to worry about their children's height was 7.7 yr. The mean age at which they started height-gain methods was 8.9 yr for herbal medicine, 9.1 yr for health-promoting supplements, 9.4 yr for exercise or machine, and 9.9 yr for growth hormone treatment. Motivating factors included advice from relatives or friends (36.0%), advertisements in the Internet or newspaper (28.4%), advice from pharmacist (16.8%), and advice from their medical doctor (5.5%). The degree of satisfaction from the height-gain methods was 29.1% with growth hormone treatment, 6.6% with exercise or machine, 6.4% with herbal medicine, and 2.8% with growth-promoting supplements. Conclusion : Approximately one third of the children reported use of growth-promoting methods, but the satisfaction rate was not high. The benefits of growth-promoting methods should be carefully weighed against their costs and side effects.

  • The in-vitro eliminative effects of against three types of herbal extract and formalin Ichthyophthirius multifiliis were examined. All parasites were killed within one hour after exposure to the 500 fold dilution of the complex herb extract whereas the 10 fold dilution of the fertilized solution of Salvia plebeia R. Br. killed all parasites within one hour after exposure. The 5,000 fold dilution of the extracts of Ginkgo biloba leaves killed all parasites within one hour after exposure. As a comparative agent, formalin killed all parasites within one hour at 100 ppm. As the results, the extracts of Ginkgo biloba leaves extracts have the most eliminative ability against the parasite. No differences were found among different parasite density in eliminative effects of the three types of herbal extracts and formalin. Also there were no changes in the fish gill tissues after exposure for two hours to the 5,000 fold dilution of the extract of Ginkgo biloba leaves.

  • Precipitation was formed during the preparation of decoction from a mixture of Scutellariae Radix and Coptidis Rhizoma. Baicalin and berberine were identified in this coprecipitated product (CPP) and these components were the active ingredients of two herbal medicine. We extracted respectively crude baicalin and berberine in Scutellariae Radix and Coptidis Rhizoma and prepared coprecipitate of crude baicalin-berberine. To increase the stability and bioavailability of coprecipitate of crude baicalin-berberine(CBB), which is slightly soluble drug, its inclusion complex was prepared and studied in this experiment. Inclusion complex of CBB with ${\beta}-cyclodextrin(CBB-{\beta}-CD)$ was prepared by freeze drying method and its characteristics were ascertained by means of solubility test, differential thermal analysis(DTA) and scanning electron microscope(SEM). The type of $CBB-{\beta}-CD$ is classified as $A_L-type$ on phase solubility diagram, and the stoichiometric ratio of CBB(baicalin in CBB) : ${\beta}-CD$ complex is 1:1 and formation constant is 151 $M^-1$. The solubility, dissolution, in situ absorption and serum concentration of $CBB-{\beta}-CD$ were significantly increased when compared to CBB. Therefore enhanced bioavailability of CBB by inclusion complexation with ${\beta}-cyclodextrin$ might be useful for dosage form design of active ingredients of two herbal medicine.

  • Precipitation was formed during the preparation of decoction from a mixure of Scutellariae Radix and Coptidis Rhizoma or Phellodendri Cortex according to the prescription of Hwang-ryean-hae-dog-tang. Baicalin and berberine, the active ingredients of the two herbal medicine were identified in coprecipitated product. Pills were prepared using the coprecipitated product and various binders. The dissolution rate of baicalin and berberine from pills was increased in at pH1.2 when acacia or tragacanth was used. The absorption rate of baicalin from the coprecipitated product was faster than that from Scutellaria extract, but the absorption of berberine from CPP was slower in stomach, duodenum and jejunum of rats compared with Coptis extract. The time required for the maximum serum concentration (Cmax) of baicalin and berberine from CPP in mice were 150 and 200 min after oral administration, respectively. The maximum serum concentration of baicalin from CPP in mice was higher than Scutellaria extract, but the concentration of berberine was lower compared with Coptis extract. The minimum inhibitory concentration of CPP was below $50\;{\mu}g/ml$ against gram positive bacteria, and was higher than that against gram negative bacteria. The antibacterial activity of CPP was lower than that of herberine, but was more potent than Scutellaria extract. It was found that the inhibition rates of growth by CPP against S. epidermidis, K. pneumoniae, B. cereus and S.aureus were 60.0, 51.1, 45.4 and 39.9%, respectively.

  • This study was performed to determine the subacute toxicities of SKI306X, an antiinflammatory herbal extract, in rats. SKI306X was administered orally to rats once a day for 4 weeks at doses of 0.3, 1.0, and 3.0 g/kg/ day. Each group consisted of 20 male and 20 female rats, including 5 male and 5 female rats per group for an interim study at the end of 2-week administration and for a 2-week recovery study, respectively. Throughout the study, all rats survived and no adverse clinical signs were observed. Although male rats treated with high dose (3.0 g/kg/day) of SKI306X showed slight loss of body weight (approximately 5%) in comparison with control animals during the administration period, their body weight loss was normally restored during the recovery period. No significant change was found in all hematological parameters of SKI306X-treated groups except for the decreased number of red blood cells in all female groups at the interim study. Statistically significant changes were observed in several blood enzyme levels of SKI306X-treated groups; however, most of these significant changes were within normal range and statistically significant values did not show dose-related responses. In SKI306X-treated groups, the absolute and relative weights of liver, heart, and stomach were statistically different from those of control group, but these differences disappeared at the end of recovery period and also drug-related gross and histopathological findings in these organs were not found. No other drug-related gross and histopathological findings were observed. It is concluded from the results of this study that non-toxic dose of SKI306X was estimated to be between 0.3 and 1.0 g/kg/day and the maximum tolerated dose of SKI306X was assumed to be higher than 3.0 g/kg/day.

  • The antimicrobial and GTase(Glucosyltransferase) inhibition activity were investigated for solvent fractions of Gall-nut, variety of fork drugs and Red-grape husk water extracts. Among them, Gall-nut and Red-grape husk water extracts were selected for the powerful antimicrobial and GTase inhibition activity. The methanol fractions of Gall-nut and Red-grape husk were showed very powerful antimicrobial activity on both B. subtilis and E. coli. The MIC(Minimum Inhibitory Concentration) of gall-nut methanol fraction were 1.0mg/ml for B. subtilis and 3.0mg/ml for E. coli. Red-grape husk were 2.0mg/ml for B. subtilis and 3.0mg/ml for E. coli. The methanol fractions of Gall-nut and Red-grape husk were showed very powerful Gtase inhibition activity. The concentrations of these fractions for 80% inhibition of GTase activity were 1.08$\times$10-3mg/ml and 1.08$\times$10-2mg/ml, respectively. The principal compound for the antimicrobial and GTase inhibition activity in tese extracts seems to be polyphenol derivatives.
