Two 17 alpha-[125I]iodovinyl estradiol derivatives 4b,d possessing high specific activity have been prepared and tested as potential radiopharmaceuticals. The use of the 3-acetyl derivatives 2c,e and the replacement of iodine monochloride with sodium iodide and Chloramine-T in THF/phosphate buffer (pH 7.0) permitted us to synthesize no-carrier-added (17(More)
We evaluated a disposable nasogastric tube with a pH sensor in comparison with an external glass pH electrode with aspiration of gastric contents, continuously. The mean pH value determined by pH sensor was 3.01, and 2.99 by glass pH electrode. There was a good correlation between the two methods (r = 0.91). The agreement between the two methods was(More)
Blood gas changes after laparoscopy under general anesthesia were examined. Thirty-six ASA I or II women were allocated to one of the two groups: carbon dioxide was used for pneumoperitoneum in group C and nitrous oxide in group N. Anesthesia was maintained with enflurane, buprenorphine, and supplemental midazolam. Arterial blood gases were measured in(More)
