Chloroquine concentrations in blood and tissues were examined in overdose and non-overdose cases to determine appropriate ranges for interpretation. Twenty-nine literature overdose cases and 8 non-overdose literature cases were compared with this laboratory's findings. The results indicate significant postmortem redistribution of chloroquine. Combining this laboratory's results and the literature results indicates that using a liver concentration of 150 mg/kg as a cutoff between overdose and non-overdose concentrations properly identified 30 of the 34 published cases containing liver chloroquine and 19 of the 20 presented cases. 相似文献

The river twisted and shrank above the beaver ponds. It neared a mountain. It was small and quiet here, full of snake-bends, oxbows and small cutthroat trout. It entered a grove of virgin Sitka spruce, and the hoof cut-trail entered in beside it. … The grove was like a vast lodge, barked pillars rising to a high mosaic of green and black and sky. A watery light filtered down, as if through stained glass. In the center of the lodge was a hollow, bordered by sword ferns and fallen logs. In the bottom of the hollow was a broad, rocky bowl eerily paved with mosshaired, head-sized stones. Among the stones was a quiet spring. And from the spring brimmed the water, old and clean and untiring. I had reached the source of the Tamanawis. 相似文献

Mild hypothermia, induced by experimental immersion of ten subjects in cold water, distorted the decay curve of breath ethanol of intoxicated subjects by as much as 22% while not altering overall ethanol clearance rate. The results provide in vivo verification of the in vitro temperature correction factor of 6.8% X degrees C-1, and support previous recommendations that temperature monitoring be included in procedures for breath-ethanol testing. We recommend that mouth temperature be obtained before breath sampling to screen for abnormal body temperature and to allow for potential use of a temperature correction factor. This modification to existing analytical procedures would help to optimize the reliability of breath-ethanol analysis in predicting blood-ethanol concentration. 相似文献

This article examines the role of federal agency budget officers and their responsibilities from the author's own perspective and experience. The article suggests that it is inadequate to standardize the role of an agency budget oficer other than that used by the agency head to determine if he or she is satisfied with the budget processes in the agency. 相似文献
