  • Chemical investigation of the fruiting bodies of Ganoderma tropicum led to the isolation of two new phenolic compounds, ganodermatropins A (1) and B (2). Their structures were elucidated by spectroscopic techniques (MS, 1D and 2D NMR). Ganodermatropin A exhibited antimicrobial activity against Staphylococcus aureus.

  • Objectives: This study was to assess the toxicity of Sipjeondaebo-tang by bacterial reverse mutation test. Methods: In this study, to evaluate the bacterial reverse mutation of Sipjeondaebo-tang water-extract, the in vitro Ames test using Salmonella typhimurium (TA98, TA100, TA1,535, TA1,537) and Escherichia coli(WP2uvrA) were performed with Sipjeondaebo-tang water extract at the concentrations 0, 312, 625, 1250, 2500 and 5000 ${\mu}g/plate$. Results: Sipjeondaebo-tang water extract was negative in Ames test with both Salmonella typhimurium or Escherichia coli with and without rat liver microsomal enzyme (S9- fraction and S+ fraction). Conclusions: According to these results, we concluded that a Sipjeondaebo-tang water extract did not cause bacterial reverse mutation.

  • 1. Objectives: The aim of this study is data analysis for acute toxicity and safety of Yangkyuksanhwa-tang. 2. Methods: We investigated the acute toxicity for water-extracted Yangkyuksanhwa-tang. 25 male and 25 female mice were observed for 14 days after one day oral administration of Yangkyuksanhwa-tang at the respective doses of 0(control group), 2560, 3200, 4000 and 5000 mg/kg. 3. Results: We observed survival rates, general toxicity, change of body weight and autopsy. 4. Conclusions: The data confirmed that Yangkyuksanhwa-tang is free from the toxicity and safety problems in oral route respectively. Compared with the control group, we could not find any toxic alteration in all treated groups(2560, 3200, 4000 and 5000 mg/kg). In conclusion, LD50 of Yangkyuksanhwa-tang was over 5000 mg/kg and it is very safe to mice.

  • Objective: To explore clinical experience and propose new ideas for treating children diagnosed with orbital rhabdomyosarcoma (RMS). Methods: We retrospectively analyzed the clinical data for30 patients (16 males and 14 females, with a median age of 6.2 years) with primary orbital RMS who were enrolled in the Department of Eye Oncology and Pediatrics of our hospital from November 2004 to December 2012. International Rhabdomyosarcoma Organization Staging Standards indicated that among the 30 patients, 4 cases were in phase II, 20 were in phase III, and 6 were in phase IV. All patients underwent a multidisciplinary collaborative model of comprehensive treatment (surgery, chemotherapy, external radiotherapy, $^{125}I$ radioactive particle implantation, and autologous peripheral blood stem-cell transplantation). Results: Follow-up was conducted until March 2013, with a median follow-up time of 47.2 months (5 to 95 months), and 7 deaths occurred. The 2-year estimated survival rate reached 86.1%, the ${\geq}3$-year estimated survival rate was 77%, and the 5-year estimated survival rate was 70.6%. Conclusions: The multidisciplinary collaborative model can be a safe and effective approach to the comprehensive treatment of children with orbital RMS. It has clinical significance in improving the tumor remission rate.

  • Sagunja-tang(Sijunzi-tang) has been traditionally prescribed as a restorative. The present study was undertaken to determine the possible toxic effects of Sagunja-tang on SD rats. In this study, we investigated the subacute toxicity of water-extracted Sagunja-tang(Sijunzi-tang) on SD rats. Twenty rats were orally adiministered Sagunja-tang for 28 days at a dose of 0 mg/kg(control group) or 1500mg/kg(treated group), respectively. All of subjects was survived. No significant difference in abnormal clinical signs, related to hematological values, serum biochemical values, water and feed intake, coagulation time, autopsy analysis, organ weight, tissue microscopically, funduscopy, urine intake and urinalysis, was detected. Compared with the control group, we could not find any subacute toxic alteration in treated group (1500mg/kg) for 28 days. This result suggests that Sagunja-tang(Sijunzi-tang). a herbal medicine prescription, is a safe prescription to body.

  • In wireless sensor networks, link scheduling is a fundamental problem related to throughput capacity and delay. For a given set of communication requests $L=\{l_1,l_2,{\cdots},l_n\}$, the MLS (maximum link scheduling) problem aims to find the largest possible subset S of Lsuch that the links in S can be scheduled simultaneously. Most of the existing results did not consider bidirectional transmission setting, which is more realistic in wireless sensor networks. In this paper, under physical interference model SINR (signal-to-noise-plus-interference-ratio) and bidirectional transmission model, we propose a constant factor approximation algorithm MLSA (Maximum Link Scheduling Algorithm) for MLS. It is proved that in the same topology setting the capacity under unidirectional transmission model is lager than that under bidirectional transmission model. However, compared with some work under unidirectional transmission model, the capacity of MLSA is improved about 28% to 45%.
