  • From 1988 to 1991, nineteen patients with unresectable localized pancreatic carcinoma were treated with radiotherapy and/or hyperthermia or in combination with chemotherapy. Radiation dose of 4500-5000 cGy with or without additional 500-1000 cGy was administered over 5 to 6 weeks to the pancreatic tumor area using 10 MV linear accelerator. Five of 19 patients were given chemotherapy, either neoadjuvant or maintenance setting with FAM regimen (5-FU, adriamycin and mitomycin C), which was repeated every 4 weeks for one year or until progression. Symptomatic palliation was achieved in 17 among 19 patients ($89{\%}$) and objective response (complete or partial response in CT finding) was achieved in 5 among 11 patients ($45{\%}$). The median survival time was 9 months and one-year survival rate, $32{\%}$. Local-regional failure was documented in 10 among 13 patients ($77{\%}$) and distant failures were found in the liver (3 patients) and carcinomatosis (2 patients). Prognostic significance of various factors such as age, sex, performance status, tumor location, stage, etc. were assessed. Any factors did not have the prognostic significance in univariate analysis. Treatment was well tolerated in most of the patients with only mild to moderate toxicity.

  • This study was demonstrate a repeated oral dose toxicity of detoxication sulphur in 8-weeks-old female Sprague-Dawley (SD) rats. The rats were treated with dose of 0.2%, 1%, 5% detoxication sulphur and 1% sulphur of feed consumption administered for 13 weeks. To evaluate the safety of detoxication sulfur, we examined the body weight, the feed intake, the clinical signs, the ophthalmological test, the hematological and the serum biochemical analysis. We also observed the histopathological changes of liver and kidney in rats. As a result, no significant differences in body weight, feed intake, hematological examination and histopathological between control and detoxication sulphur treatment group were found. Serum biochemical results were not shown significant differences in 0.2% and 1% the treated groups compared with control group. But glucose level were decrease, also ALT and ALP level were increase in 5% treated group. All of these results indicate that 1% detoxication sulphur of feed consumption may be safety in SD rat.
