HIV/AIDS drug development and treatment

The patients were admitted to the Metabolism Ward where they were under continuous observation.The urine was analyzed daily for sodium, potassium, phos- phorus, chloride, and nitrogen; aliquots of the 24-hour collections of urine were saved and pooled in periods of five days, and the analyses repeated on the pooled sam- ples.This served as an added check on the accuracy of the daily work.Stools were separated at intervals of five days with the use of carmine markers and analyzed for the same constituents as in the case of urine.Sample diets, duplicating the menus of the patients, were prepared at intervals of ten days, homogenized, sampled, and analyzed to determine intake.Emeses and dietary re- jects were treated in the same manner as sample diets, analyzed separately, and appropriate corrections of in- take were made.Blood was collected in the postabsorptive state from an arm vein with the least possible stasis, and after prompt separation of the serum, determinations were made of total serum protein, albumin, globulin, so- dium, chloride, potassium, calcium, and phosphorus.The analytical methods used were as follows: Aliquots of diet, urine, and emesis were ashed in a muffle furnace at a temperature not exceeding 4500 C. Sodium and po- tassium determinations were performed directly on di- luted specimens of urine and (blood) serum, with the use of the Beckman flame photometer.With the excep- tion of nitrogen and chloride, the other substances were determined from the ashed filtrates.Urinary, fecal, and dietary calcium were determined by the gravimetric method of Washburn and Shear (12), serum calcium by the method of Van Slyke and Sendroy (13), phosphorus by the gravimetric method of Washburn and Shear (12), and a modification of the colorimetric method of Fiske and Subbarow (14), nitrogen by the Hiller, Plazin, and Van Slyke modifications of the Kjeldahl procedure (15), chlorides by modification of the Volhard method (16-18), plasma proteins by a modification of the Howe sodium sulfate method (19) as described by Majoor (20), and urinary protein by the method of Hiller, Greif, and Beck- man (21), serum and urine uric acid by modification of the methods of Kalckar ( 22) and Praetorius (23).103 * Grams protein per five-day period.metabolic unit for studies which were continued for 75 Patient 3 (S.M.)
