ABSTRACT
To study the distribution and localization of oil-soluble arteether in experimental mice, we injected C14-labelled arteether (20 microCi/kg body weight) intramuscularly and measured radioactivity in the blood, kidney, and liver. The labelled arteether distributed and localized more to the kidney (819,180.4 +/- 34,134 dpm/cm3) than the liver (288,628.9 +/- 54,954 dpm/cm3) 4 hours post-injection. The main localization of labelled arteether was in the kidney cortex rather than the medulla (p < 0.05). However, the distribution of radioactivity was homogeneous in the liver. The terminal half-life of labelled arteether in the blood was 1.8 hours. The blood:kidney:liver ratio was 1:5:2. These findings show that labelled arteether was distributed quickly and localized in the cytoplasmic cortex of the kidney and homogeneously in the liver.

Typing of dengue viruses was done for clinical specimens from a total of 136 patients (children under 15-years-old) suspected of having dengue virus infections and who had been admitted to Pathum Thani Provincial Hospital during the period May 1999 to April 2000. Altogether, 44 strains were isolated (isolation rate: 32.4%), consisting of 18 DEN-1, 18 DEN-2, 7 DEN-3 and 1 DEN-4. The isolation rate decreased according to the number of days after the onset of disease, from day 4 to day 8.

Leishmania tropica (cutaneous leishmaniasis) can be detected easily, rapidly, and conveniently by the examination of a skin ulcer smear that is stained with a modified method of Wright staining of blood (ie that used for routine hematological examinations).
