An enzymatic assay for creatine, depending on the creatine kinase reaction, has been modified for the determination of creatine in packed erythrocytes, using a centrifugal analyzer (COBAS BIO). The method is precise, sensitive and shows excellent accuracy in recovery experiments when compared to the diacetyl-alpha-naphthol method. The enzymatic red cell creatine correlates with the erythrocyte survival time determined with the radioactive chromium method. It can be used as a rapidly available parameter for the quantification of hemolytic processes. 相似文献

At the time of publication of this journal, the Center for Urinary Control in Memphis, Tennessee, has performed eight office-based
surgical procedures using anesthesia. Patients were aged between 56 and 80 years, and all were ASA I–III class. The procedures
involved either cystoscopy with collagen injection into the bladder neck or cystoscopy with indigo laser treatment of the
prostate. All patients were prepared by the anesthesiologist prior to the day of surgery, and appropriate laboratory tests
were ordered and evaluated. All patients did very well, the surgical field was quiet, and each procedure went very smoothly.
Each patient tolerated anesthesia without any adverse effect, was recovered in an adjacent examination room, and was extremely
satisfied upon discharge from the office. Anesthesia was induced with Propofol (Diprivan) and sublimaze, maintained with a
Propofol infusion and oxygen. The surgeon performed a periprostatic block on the patient having the Indigo laser treatment. 相似文献

Although viral respiratory tract infections may predispose to meningococcal disease, strong evidence that they do so exists only for influenza. Data on laboratory reported cases of respiratory syncytial virus (RSV) infections and meningococcal disease in England and Wales from mid-1989 to mid-1994 were analysed. Although the rise in RSV cases preceded the rise in meningococcal disease cases each winter, the interval between the rise and fall of the two diseases was inconsistent, no association was found between time series after removal of the seasonal component, and there was no evidence that more cases of meningococcal disease occurred in winters with more RSV disease. RSV may have less effect on the two most likely mechanisms whereby influenza predisposes to meningococcal disease, namely lowered immunity and impaired pharyngeal defences. 相似文献

We examined the internal jugular veins in three groups of patients who had undergone (1) a functional neck dissection and radiotherapy, (2) a functional neck dissection alone, or (3) radiotherapy alone, using a noninvasive color Doppler ultrasound scan. The internal jugular veins were ultrasonically bilaterally normal in 18% of patients who had undergone a functional neck dissection and radiotherapy, in 88% of patients who had undergone a functional neck dissection alone, and in 57% of patients who had undergone radiotherapy alone. The combination of a functional neck dissection and radiotherapy significantly affected the internal jugular vein when compared with a functional neck dissection alone. 相似文献

Summary The highly lipophilic cyanomorpholinyl adriamycin (CMA) is the most potent antineoplastic anthracycline yet described. CNS distribution and toxicity were examined after i.v. administration of CMA to mice. At doses 0.1 mg/kg, a neurotoxic syndrome including ataxia, hypokinesia, and tremors appeared. At doses of 0.05 mg/kg, which have been reported to be antineoplastic, no neurotoxicity was observed. On histopathologic examination, no changes were observed in the brain, spinal cord, or dorsal root ganglia. Unlike adriamycin (ADR), which rapidly appears in the nuclei of several tissues, CMA showed no fluorescence, suggesting a different cellular microcompartmentalization. The i.d. injection of CMA disclosed a 200-fold increase in toxicity compared with that of adriamycin. In comparisons of CMA and ADR, neurotoxicity and cardiotoxicity occurred equally only at higher doses; however, the dermatotoxicity and antineoplastic activity of CMA were increased several hundred-fold. 相似文献
