Curcumin and curcumin containing polyherbal preparations have demonstrated anti-microbial and antiviral properties in pre-clinical studies. Till date no therapeutic intervention has been proved to be effective and safe in clearing established cervical human papillomavirus (HPV) infection. The present study evaluated the efficacy of Basant polyherbal vaginal cream (containing extracts of curcumin, reetha, amla and aloe vera) and of curcumin vaginal capsules to eliminate HPV infection from cervix. Women were screened by Pap smear and HPV DNA test by PCR. HPV positive women without high grade cervical neoplasias (N=287) were randomized to four intervention arms to be treated with vaginal Basant cream, vaginal placebo cream, curcumin vaginal capsules and placebo vaginal capsules respectively. All subjects were instructed to use one application of the assigned formulation daily for 30 consecutive days except during menstruation and recalled within seven days of the last application for repeat HPV test, cytology and colposcopy. HPV clearance rate in Basant arm (87.7%) was significantly higher than the combined placebo arms (73.3%). Curcumin caused higher rate of clearance (81.3%) than placebo though the difference was not statistically significant. Vaginal irritation and itching, mostly mild to moderate, was significantly higher after Basant application. No serious adverse events were noted.

This study was carried out to investigate varietal differences on growth characteristics under the conditions of PE film-mulching and non-mulching in sesame. At maturing stage from 76 to 95 days after sowing, Yangbaeckkae, non-branching plant type, under non-mulching showed larger leaf area index (LAI) than that of film-mulching, while plant height and the number of capsules per plant were similar to those of film-mulching. LAI of Ahnsankkae, branching plant type, under non-mulching was similar to film-mulching, while plant height and the number of capsules per plant were smaller than those of film-mulching. Net assimilation rate (NAR) of two varieties under non-mulching was lower at seedling stage from 25 to 35 days after sowing but higher at flowering stage from 45 to 55 days after sowing. At maturing stage from 66 to 77 days after sowing, NAR and crop growth rate (CGR) of Yangbaeckkae under non-mulching were greater than those of film-mulching, whereas those of Ahnsankkae under non-mulching were lesser than those of film-mulching. Yield under non-mulching was decreased by 7 % in Yangbaeckkae and 33 % in Ahnsankkae compared with that of film-mulching, therefore Yangbaeckkae was more adaptable for non-mulching than Ahnsankkae. Main factors decreasing yield of Yangbaeckkae under non-mulching were small LAI, NAR, and CGR at the stage of young seedling, and small number of capsules at early maturing stage from first flowering to 20 days after first flowering.

Hepatocellular carcinoma (HCC) is the fi fth most common malignancy in the world and complicates liver cirrhosis related to hepatitis C virus (HCV) in many cases. We evaluated the therapeutic effect of Korean red ginseng extract (KGE) in patients with chronic liver diseases. Thirty male and female patients with HCC and another thirty with liver cirrhosis were included. Each category was divided into two groups; the first was used as control group, and received medical therapy only and the second group received the medical therapy supplemented with KGE capsules. The treated group with HCC received three KGE capsules/day (900 mg) while the treated group with HCV received two KGE capsules/day (600 mg) for 11 weeks along with their medical therapy. All patients were subjected to clinical examination and laboratory investigations, including liver function tests (at baseline, after 6 weeks of treatment and at the end of the study) and abdominal ultrasonography. Patients showing focal hepatic lesions were subjected to triphasic spiral abdominal computerized tomography and alpha-fetoprotein (AFP). HCV RNA was determined quantitatively by Roche for patients in the HCV group. Results showed that the medical therapy alone failed to normalize the liver enzymes or decrease the virus concentration. KGE administration induced a significant improvement in liver function tests, decreased the tumor marker (AFP) levels, and decreased the viral titers in HCV patients. Thus, KGE demonstrated powerful therapeutic effects against HCV and liver cancer.

Cephradine is an orally absorbed cephalosporin with a broad spectrum of activity against gram-positive and gram-negative bacteria and is highly resistant to beta-lactamase degradation. The purpose of the present study was to evaluate the bioequivalence of two cephradine capules, Cephradine capsule (Donggu Pharmaceutical Co., reference drug) and Cephradine capsule (Shinpoong Pharmaceutical Co., test drug), according to the guidelines of Korea Food and Drug Administration. Twenty-six normal volunteers, 24.6 $\pm$ 3.70 years in age and 62.4 $\pm$ 8.99 kg in body weight, were divided into two groups and a randomized 2 $\times$ 2 cross-over study was employed. After one capsule containing 250 mg of cephrdine was orally administered, blood was taken at predetermined time intervals and the concentrations of cephrdine in serum were determined using HPLC with UV detector. The pharmacokinetic parameters such as AU $C_{t}$ to $C_{max}$ and $T_{max}$ were calculated and ANOVA test was utilized for the statistical analysis of the parameters. The results showed that the differences in AUCt, $C_{max}$ and $T_{max}$ between two products were 2.89％, 1.05％ and 1.06％, respectively, when calculated against the reference drug. The 90％ confidence intervals were within log0.8 $\leq$ $\delta$ $\leq$ log1.25 (e.g., log0.9803 $\leq$ $\delta$ $\leq$ log1.0734 and log0.9674 $\leq$ $\delta$ $\leq$ log1.220 for AU $C_{t}$, and $C_{max}$, respectively). Two parameters met the criteria of KFDA for bioequivalence, indicating that Cephradine capsules (Shinpoong Pharmaceutical Co.) is bioequivalent to Cephradine capsules (Donggu Pharmaceutical Co.).o.).o.).).o.).

This study was performed to obtain the information on fruit set, propagation and flowering habits of the exotic ornamental bottle brush tree (Callistemon citrinus). Trees have fruit capsules for four years since the fruit set and they have enlarged for three years. While 2 and 3-year-old capsules have similar seeds in number and size, 1-year-old ones have fewer and smaller seeds. Most dried capsules open when they have 75％ relative water contents. Two year old seeds which they were dried at 30％ germinated better than others. Removal of capsule bearing twigs resulted in greatly increased subsequent flower numbers (an average of 14 flowers per tree) compared with twigs where seed capsule were allowed to remain. In cutting for propagation, semi-hard wood branches dipped in 100mgι$^{-1}$ IBA for 24 hours rooted at 86.4 ％ and had an average of 12.6 primary roots.

The aim of this work is the fabrication of polyelectrolyte microcapsules composed of biocompatible polymers such as chitosan, heparin and alginate, to encapsulate the fluorescein isothiocyanate(FITC)-albumin, and to investigate the protein release behavior therefrom. Polyelectrolyte capsules with 4-layer structures could be prepared with biocompatible materials by oppositely charged adsorption using melamin-foramide as a template. Transmission electron microscope(TEM), scanning electron microscope(SEM) and optical microscope confirmed hollow capsule structures. Protein release before and after encapsulation was monitored with a UV-Vis spectrometer. Microcapsules have different behaviors depending on the kind of polyelectrolyte polymers, chitosan-heparin capsules or chitosan-alginate capsules. In conclusion, the polyelectrolyte multilayer shells can be switched between an open and closed state by means of tuning the pH value.

The objective of this study is to determine the physical characteristics of the gel mass of vegetable soft capsules and to maintain their rheological stability for improving manufacturability. The effect of each capsule shell component on the viscosity of the gel mass was studied for 6 hours, and the effects of adding an alkalizer or electrolytes to neutralize the sulfate groups on the carrageenan molecule were also investigated. Carrageenan was identified as a major component that affects the viscosity of the gel mass, and it showed unstable properties with age. The viscosity and stability of the gel mass were remarkably improved when an alkalizer or electrolytes were added at 3.0% relative to the carrageenan. 3.6 M KCl showed the highest effect on increasing the viscosity. A stable gel mass composition for vegetable soft capsules was successfully developed, which can be considered to increase the application of the capsules in the pharmaceutical and food industries.

In this study, the self-healing hybrid capsules were prepared, were mixed with 3 %, 5 %, and 7 % based on cement mass. The healing performance were evaluated according to mixing ratio self-healing hybrid capsule. As a result of the experiment, it was found that the crack healing performance improved as the mixing rate of the self-healing hybrid capsule increased, but the quality performance tended to decrease. Therefore, it is judged that using the mixing ratio of the hybrid capsule within 5 % reduces the quality performance to within about 10 % and secures about 90 % or more of the healing performance.

The habit of anthesis and maturity of sesame were investigated as a basic research for the improvement of high-yielding varieties and cultural practices. Eight different plant types were identified using typical cultivars among gene pool grown in Korea. Non-branching, Monocapsule, Bicarpels quadriloculi (NMB) type showed higher ratio for capsule setting compared with Non-branching, Monocapsule, Quadricarpels octoloculi (NMQ) type. Non-branching, Tricapsules, Quadricarpels octoloculi(NTQ) type presented lower ratio for capsule setting than non-branching, tricapsules, bicarpels quadriloculi(NTB) type. The number of flowers by flower setting position was the highest on lower part, intermediate on middle part, and the lowest on higher part in NMB and NTB type. However, the number of flowers was the highest on middle part, intermediate on lower part, and lowest on higher part in NMQ and NTQ type. BMB type appeared to have the highest ratio for capsule setting when compared with the other plant types. BTB type with many flowers and capsules exhibited higher percentage for capsule setting than BTQ type with lowest capsule setting percentage. Capsule setting percentage of branch appeared to be lower than that of main stern in the branching type. The branching type had more flowers and capsules than non-branching type. Tricapsules type had more flowers and capsules per plant than monocapsule type, and bicarpels quadriloculi type had more than quadricarpels octoloculi type. However, capsule setting ratio in non-branching type was higher than in branching type. The ratio was higher in monocapsule type than in tricapsules type. Bicarpels quadriloculi type had higher ratio of capsule setting than quadricapels octoloculi type. Number of capsules per plant and capsule setting ratio are supposed to be dominated by shape of capsule (number of carpels and loculi), not by branching or number of capsules per axil. The order of number of capsules per plant was as follows; BTB, BMB, NTB, BTQ, BMQ, NTQ, NMQ, and NMB types. However, the order of capsule setting ratio was as follows: BMB, NMB, NTB, NTQ, NMQ, BMQ, BTB, BTQ types. Consequently, branching, tricapsules, bicarpels quadriloculi(BTB) type was considered as a sourse of breeding for high yielding varieties by introducing the genes govering BMB type with one capsule per axil which has high capsule setting ability.

Background: Ma-huang (Ephedra sinica) has been widely used to treat respiratory disease in oriental medicine for over a hundred years. Ma-huang preparations contain approximately 1.25% ephedrine alkaloids. Recently, the ephedra alkaloids have received much press lately due to adverse effects in those using whole extracts as 'dietary supplements' for weight loss or athletic performance enhancement, and these reports are troubling given the increasing use of Ma-huang by the general public. The purpose of this report is to determine the proper dosage to minimize adverse effects and maximize the potential curative value. Objectives : The object of this study was to find an effective yet low risk dosage of Ma-huang. Methods : The study was designed as a double-blind randomized placebo-controlled trial. The subjects of this study were 26 adults between 20 to 40 of age who agreed to participate in this study. They were allocated through randomization into three groups. Each group took three opaque capsules three times a day. A group (N=9) took one Ma-huang capsule and two placebo capsules, B group (N=8) took two Ma-huang capsules and one placebo capsule, C group (N=9) took three Ma-huang capsules. The total trial periods was two days. To compare the adverse effects of Ma-huang according to dosage, blood pressure and pulse were checked, and other adverse effects were assessed using a morning questionnaire, patient's global assessment scale and Wong-Baker faces pain rating. Results : The following result were obtained: 1. After taking 18 g of Ma-huang per day, pulse rate had a significant increase. 2. After taking more than 6 g of Ma-huang per day, palpitation would be increased significantly. 3. After taking more than 18 g of Ma-huang per day, tiredness would be increased significantly. Conclusion: According to the results, 12 g of Ma-huang per day will minimize adverse effects and maximize the potential curative value.
