For the most part, 1983 was a quiet year in the otherwise occasionallytumultuous relationship between higher education and the governorsof the American states. To be sure, there were growing indicationsof serious budget problems on the horizon, exacerbated by droppingenrollments and shifting needs among students, faculty, andsociety. There was also an increasing awareness throughout thecountry of the future significant role that high technologymight play in institutions of higher education; but these prospectsstill need to be worked on and sorted out. The year provides,therefore, a good opportunity to look back at the fundamentalrelationship between governors and higher education and to examinea few specific areas of longstanding concern so that we maybe better prepared for what lies ahead. 相似文献

Gas chromatographic/mass spectrometric analysis of morphine and codeine in human urine of poppy seed eaters 总被引:1,自引:0,他引:1

In this study, poppy seeds were examined for a natural constituent that might serve as a maker for the seeds' ingestion as opposed to opiate abuse. Thebaine was selected as possible marker, since it was found to be a component of all poppy seeds examined and was not a natural component of different heroin samples. During the course of this investigation, a new extraction and cleanup procedure was developed for the gas chromatographic/nitrogen phosphorus detection (GC/NPD) and gas chromatographic/mass spectrometric (GC/MS) analysis of morphine and codeine in urine. A linear response, over a concentration range of 25 to 600 ng/mL, was obtained for codeine and morphine (r = 0.9982 and 0.9947, respectively). The minimum detectable level (LOD) and limit of quantitation (LOQ) for morphine were 10 and 30 ng/mL, respectively; whereas LOD and LOQ for codeine were 2 and 8 ng/mL, respectively. The coefficients of variance (CV, n = 6) for morphine and codeine analyses at the 100-ng/mL level were 13.3 and 4.6%, respectively. This procedure was used for the analysis of urine samples from five poppy seed eaters who each ingested 200 g of poppy seed cake. Results indicated that significant amounts of morphine and codeine are excreted in urine and that in all subjects, at least at one point in time, the apparent morphine concentration as determined by radioimmunoassay (RIA) analysis exceeded the cutoff value (300 ng/mL) established for screening. Thebaine was not detected in urine specimens collected following poppy seeds ingestion and thus could not be used as a marker. 相似文献

Yellow oleander poisoning--a study of 170 cases 总被引:1,自引:0,他引:1
Yellow oleander or Thevetia peruviana is a very common plant in the North of Sri Lanka. Ever since the fact that the fruits and kernel are poisonous was published in the Newspapers, many cases of poisoning due to Thevetia occurred. 170 cases of Thevetia poisoning admitted to the Teaching Hospital, Jaffna in the North of Sri Lanka are studied by the authors. The mortality, morbidity, age distribution, presenting symptoms and clinical findings are analysed. The action of the cardiac glycoside in Thevetia is clearly demonstrated in this study. 相似文献

Two cases of acute intoxication of buflomedil hydrochloride are reported. The analysis of this compound was performed by an Extrelut extraction followed by a gas chromatographic-mass spectrometric determination. Analytical parameters of linearity, reproducibility and specificity were satisfactory. 相似文献
