The purpose of this study was to examine the radiolabeling and biodistribution of 188Re(V)-DMSA as a therapeutic cancer radiopharmaceutical. We made a DMSA kit(NaHC03 1.5 mg, meso-2,3-dimercaptosuccinic acid 1.0 mg L(+)-ascorbic acid 0.7mg, SnCl2 2H2O 0.34 mg, pH 2.9) for labeling with 188Re. In this kit, 188ReO4- 5 mCi/2 ml added and boiled at 100 degree C for 3 hr in water bath. The final pH adjusted to 7.5 with 7% NaHCO3 solution. We checked the labelling efficacy with TLC-SG(n-butanol : acetic acid:H2O = 3 : 2 : 3) and examined the stability both in room temperature and in serum at 37 degree C. Biodistribution(l, 3, 13, 24, 48 hr) of 188Re(V)-DMSA compound was evaluated in Sarcoma 180 tumor-bearing mice. Each labeling efficiency and stability at room temperature for 48 hours was over 98% and 95%, respectely. The stability in serum were 82%(6 hr) and 85%(48 hr). Tumor uptake of 188Re(V)-DMSA in Sarcoma 180- bearing mice were 0.66+/-0.15%(1 hr), 0.51+/-0.10%(3 hr), 0.19+/-0..05%(24 hr) and 0.13+/-0.02%(48 hr). These result are consistent with those of 99mTc(V)-DMSA which were reported previously In conclusion, 188Re(V)-DMSA may be a useful therapeutic radiopharmaceutical for treating some cancers and metastatic bone lesion.

This is our first time report of S-180 cell handled with various voltages, capacity and pulse number. Many pores on the S-180 cell membrane can be observed under scanning electron microscope. By the stains of trypan blue, we have known the influence of electric parameters on the ratio of poration. The results show that the ratio of electroporation has positive correlation with the voltages and the pulse number while negative correlation with the capacity.

OBJECTIVE: To explore the antitumor effects of ethanol extract from Ventilago leiocarpa Benth (EEVLB) on sarcoma 180 (S180) tumor-bearing mice and the potential mechanism. METHODS: Sixty mice were randomly assigned to 6 groups according to a random number table: normal group, model group, 5-fluorouracil (5-FU) group (0.02 g·kg RESULTS: EEVLB with different concentrations achieved inhibition of tumor growth in vivo, wherein the high-dose group showed the most significant reduction in tumor weight and increased apoptosis of tumor cells (P<0.05). In addition, both net weight gain and spleen index of mice showed uptrend in EEVLB treatment groups (P<0.05). Besides, serum levels of IL-2 and IL-6, percentages of CD3 CONCLUSIONS EEVLB exhibits promising antitumor activity in vivo. This effect might be due to activation of apoptotic signaling pathway, increase of cytokine levels and enhancement of immune function in tumor-bearing mice.

Oudemansiella radicata, one of edible mushrooms belonging to Tricholomataceae of Basidiomycota, has been known to exhibit outstanding therapeutic effects on the hypertension caused by high blood pressure and inhibitory effects on the sarcoma 180 and Erhrlich carcinoma of mice. As one of preliminary experiments for producing fruiting-body of O. radicata, this study was carried out to obtain the basic information for culture conditions of mycelial growth of the fungus. The optimal temperature and pH for the mycelial growth were 25degrees C and pH 6, respectively. The medium for favorable mycelial growth of O. radicata was shown in the Lilly medium, whereas compact mycelial density was found in Hamada medium. The carbon and nitrogen sources promoting for mycelial growth of O. radicata were xylose and alanine, respectively. The optimum C/N ratio was about 20 : 1 in case that 3% glucose was supplimented to the basal medium as a carbon source.

The anti-tumor effects of exo- (EX) and endo-biopolymers (EN) produced from submerged mycelial cultures of Ganoderma applanatum (GA), Collybia confluens (CC), and Pleurotus eryngii (PE) were studied using Sarcoma 180 bearing mice. Solid tumor growth was inhibited most effectively when 40 mg/kg body weight (BW) of GA-EX or PE-EN was administered to the intraperitoneal (i.p.) cavity of BALB/c mice. The spleen and liver indexes were increased in mice following i.p. administration of GA-EX and PE-EN fractions. GA-EX and PE-EN reduced the tumor formation by 30.7% and 29.4%, respectively. GA-EX and PE-EN increased the natural killer (NK) cell activity of splenocytes by 41.3% and 28.9%, respectively.

Korl:ICR mice, established by the Korean National Institute of Food and Drug Safety Evaluation (NIFDS), are characterized based on their genetic variation, response to gastric injury, and response to constipation inducers. To compare the inhibitory responses of ICR stocks obtained from three different sources to the anticancer drug cisplatin (Cis), alterations in tumor volume, histopathological structure, and toxicity were examined in Sarcoma 180 tumor-bearing Korl:ICR, A:ICR (USA source), and B:ICR (Japan source) mice treated with low and high concentrations of Cis (L-Cis and H-Cis, respectively). Tumor size and volume were lower in H-Cis-treated mice than in L-Cis-treated mice in all three ICR stocks with no significant differences among stocks. There was a significant enhancement of the necrotizing areas in the histological structures in the L-Cis- and H-Cis-treated groups relative to that in the untreated group. The necrotizing area changes were similar in the Sarcoma 180 tumor-bearing Korl:ICR, A:ICR, and B:ICR mice. However, there were stock-bases differences in the serum biomarkers for liver and kidney toxic effects. In particular, the levels of AST, ALT and BUN increased differently in the three H-Cis-treated ICR stocks, whereas the levels of ALP and CRE were constant. Taken together, the results of the present study indicate that Korl:ICR, A:ICR, and B:ICR mice have similar overall inhibitory responses following Cis treatment of Sarcoma 180-derived solid tumors, although there were some differences in the magnitude of the toxic effects in the three ICR stocks.
