a,-Microglobulin levels in serum and urine were estimated by using single radial immunodiffusion, resulting in the following mean values: umbilical cord blood serum, 40*6 mg/I; normal adult serum, 44-2 mg/I; and normal urine, 5 7 mg/24 h urine volume. Slightly higher levels of serum a1-microglobulin were found in infants and the aged. Serum and urine a,-microglobulin levels in patients with ren...

Examination of the lumbar cerebrospinal fluid in the diagnosis of cerebral tumour is less often resorted to than formerly, partly because in some instances there may be a risk of coning after lumbar puncture, but more especially because arteriography and ventriculography are now more frequently used for locating the tumour and examination of the ventricular fluid is often found to be more conve...

In the course of experiments on the transmission of radioactive sodium across the human placenta it became necessary to examine the way in which sodium diffuses in the newly born infant. Studies of this problem have already been reported by Flexner, Wilde, Proctor, Cowie, Vosburgh and Hellman (1947) and by Perley, Forbes and Pennoyer (1951). It was thought that some additional information might...

A large array of studies have investigated peripheral oxytocin (OT) and vasopressin (ADH) as potential biomarkers of psychiatric disorders, with highly conflicting and heterogenous findings. We searched Web of KnowledgeSM and Scopus® for English original articles investigating OT and/or ADH levels in different biological fluids (plasma/serum, saliva, urine and cerebrospinal fluid) across severa...

conclusions: even, very low amount of csf-igg with good specificity (90%); could differentiate cases and controls (p = 0.000). the csf-igg test (sensitivity 70%, npv 28.8%) was weak for ruling out the m. pneumonia in cases. positive pcr was rare (2%) in csf of cases and controls but is more reliable for diagnosing the recent m. pneumonia infection. we prefer to assay the csf for both serology a...

Heroin (3,6-diacetylmorphine) is rapidly hydrolyzed to 6-monoacetylmorphine, which is further hydrolyzed to morphine (1). In this retrospective study, samples of biological fluids were analyzed for free morphine because it is the primary analyte found in biological samples obtained from victims of heroin fatalities (2). Of 1,175 cases reviewed, 29 heroin-induced fatalities were identified. Vict...

OBJECTIVE To determine amount of syringes used in the hospital and extent of contact with blood and body fluids of these syringes. MATERIAL AND METHODS Syringe use was surveyed at a tertiary care center for one week; syringes were classified into the following four categories according to use: a) contained blood; b) contained other body fluids (urine, gastric secretion, cerebrospinal fluid, w...
