  • A simple and selective isocratic HPLC method for the analysis of tissue polyamine contents is described and applied on the study of the changes of the hepatic polyamine contents after partial hepatectomy in male rats. The hepatic polyamines are extracted with 0.4 M perchloric acid containing 2 mM disodium EDTA, and then the extract is redissolved in 100 ul of 1 M sodium carbonate and incubated with 300 ul of FNBT-dimethylsulfoxide (1: 100) mixture. The N-2'-nitro-4'-trifluoromethylphenyl drivatives of polyamines are separated through a ERC-ODS column in an isocratic mode with an acetonitrile-water (80:20) mobile phase within 20 min. per a sample, while monitoring the effluent at 242 nm. This improved method which could detect subnanogram of each polyamines is highly specific and reproducible as evidenced by the application of it on the study of the changes of polyamine contents in the regenerating rat liver after partial hepatectomy.

  • Background: The natural history of bacillary tuberculosis was studied in India and results showed that at the end of the 5-year period, 49% of the patients were dead, 33% were cured and 18% remained sputum-positive. The aim of this survey is to observe the natural course of the patients with intractable tuberculosis disease who were incurable with all drug regimens of the national tuberculosis programme(NTP). Method: Of the patients who have been found as intractable cases in Kang-Weon Province by the supervisory medical officer during the period from January 1,1987 to December 31,1992, 179 were eligible for this study. Sputum examination was done for those who were survived until October in 1993 at the Kang-Weon provincial laboratory of KNTA. 49 out of 179 patients were transferred to the private sectors and retreated with the combination of prothionamide, cycloserine, ofloxacin, enviomycin, etc. They seemed to have been bacteriologically cured, and so they were excluded from the study. Finally 130 patients were analyzed by modified life table method to calculate the fatality rate and the survival rate during the period of 7 years. Results: 1) 80.8% of intractable cases were male and 19.2%, female. 2) More than 94% of intractable cases showed moderately or far advanced Tb findings on their X-rays at the time of registration at health centres. 3) The cumulative case-fatality rate was 19.74% at the end of 1-year period and has risen to 34.55% by the end of 4-year period(increasing by 4.9% a year on an average). The case-fatality rate has shown no appreciable rise since then until the end of 7-year period. 4) The case-survival rate was 80.26% at the end of 1-year period and has decreased to 65.45% by the end of 4-year period. And then there was no appreciable change in the survival rate until the end of 7-year observation. Conclusion: The case-survival rate of intractable cases was higher than that of untreated pulmonary tuberculosis patients and they may have risk of spreading multidrug resistant organisms. It is time we made an effort to improve case-management qualitatively.
