[Total protein and immunoglobulin levels in the body fluids of healthy and Rh-incompatible pregnant women].

The content of total protein and immunoglobulins in blood serum, saliva and breast-milk of healthy pregnant women and of pregnant women with anti-D-antibodies has been determined by the biuret-method and radial immunodiffusion. The values of immunoglobulins in every body fluid are typical and they respond to pregnancy. The investigations vindicate theory of local antibody synthesis. The differences of immunoglobulins from healthy pregnant women and from patients with antibodies were discussed.

Human serum mannose binding protein (MBP): development of an enzyme-linked immunosorbent assay (ELISA) and determination of levels in serum from 1085 normal Japanese and in some body fluids.

We developed an enzyme-linked immunosorbent assay (ELISA) for human serum mannose binding protein (MBP), an animal lectin known to function as opsonin and complement activator. A total of 1085 normal Japanese sera from individuals ranging in age from 3 to 100 years old and additional body fluids were measured for the MBP level. Individual serum MBP levels ranged from 0.07 to 6.40 micrograms/ml with a frequency distribution profile of the log-normal type. Arithmetic mean +/- standard deviation (M +/- SD) of serum MBP as a whole was 1.72 +/- 1.15 micrograms/ml, whereas those of cerebrospinal fluid and urine were 1/100 and 1/1000 of serum levels, respectively. When the M +/- SD of serum MBP was calculated for each age group (10-year intervals) and compared, the value declined from age group of 3-9 years old (2.42 +/- 1.31 micrograms/ml) to that of 20-29 years old (1.72 +/- 1.03 micrograms/ml), and thereafter it remained almost constant. Comparing the frequency distribution profile among each group, that of young group revealed a distinct bimodal pattern, one peak at around 1 micrograms/ml and the other at 3 micrograms/ml. The latter peak was gradually depressed with advance of age and finally a typical log-normal type appeared after the age of 30. There was a high age dependency in serum MBP level as well as in distribution profile. It should be stressed that care should be taken with age in the evaluation of MBP level.

Relaxin: a pregnancy hormone as central player of body fluid and circulation homeostasis.

The peptide relaxin has long been regarded as an important hormone of pregnancy, contributing to changes in connective tissue composition as well as to regulation of implantation, myometrial activity and labor. On the other hand, the astonishing pleiotropy of this hormone escaped scientific awareness. This review focuses on new facets of relaxin, including its antifibrotic effects, its role in the control of pituitary hormone release, its vasodilator and pro-angiogenic properties and its versatile myocardial actions. Recent progress in understanding relaxin's receptor and signaling mechanisms is also highlighted. The peptide will be characterized as potential regulator of body fluid and circulation homeostasis.

The use of the PREP system for handling of body fluids.

The Du Pont PREP automated sample processor is a centrifugally based, microprocessor controlled instrument that was designed for extraction of samples from biological fluids. Extraction takes place in cartridges containing either organic resins or bonded silica packings as extraction sorbants. This paper will discuss the application of several lipophilic and ion exchange sorbants to the extraction of biological samples from body fluids. The advantages of these different types of sorbants will be compared and their performance with automated sample preparation will be shown. A variety of applications including the extraction of benzodiazepine, barbiturate, aminoglycoside and anticonvulsant drugs and their metabolites from serum, urine, and tissue homogenates will be discussed.

Immunoassays for the determination of human tissue kallikrein (TK) in different body fluids based on monoclonal antibodies.

A monoclonal antibody produced against human tissue kallikrein was used to develop solid phase immunoassays for the determination of total immunoreactive tissue kallikrein, of the complex of tissue kallikrein with alpha 1-proteinase inhibitor, and of enzymatically active tissue kallikrein. The assays permit the specific determination of various forms of tissue kallikrein in body fluids and should be very useful in studies on the biological function of tissue kallikrein-kinin systems.

Comparison of BACTEC plus Aerobic/F, Anaerobic/F, Peds Plus/F, and Lytic/F media with and without fastidious organism supplement to conventional methods for culture of sterile body fluids.

We compared the BACTEC 9240 continuous-read instrument using Peds Plus/F, Lytic/F, Aerobic/F, and Anaerobic/F media (Becton Dickinson Diagnostic Instrument Systems, Sparks, MD) with and without fastidious organism supplement to conventional centrifugation preparation and plating for the recovery and speed of detection of microorganisms. A total of 908 sterile body fluid specimens were collected and processed, yielding 116 (13%) positive cultures. Of the 80 isolates considered clinically significant, 48 (60%) were recovered by both the BACTEC system and conventional culture, whereas 32 (40%) were recovered by BACTEC only. No clinically significant isolates were recovered only by conventional culture methods. The time to detection for isolates recovered from both sets was faster for BACTEC. It was found that BACTEC, with or without the addition of fastidious organisms supplement, exhibited improved sensitivity for the recovery of microorganisms.

[A system for testing alternating frequency properties of body fluid and tissues].

The electric properties of biotic tissues are of importance to our understanding biotic substances even life. But the measurement taken in this aspect is different from the measurement of ordinary materials, we need a special testing instrument for living substances. In order to understand the alternating frequency properties of body fluid and tissues in detail, we have developed an electricity characteristic testing system, which is more proper for testing living substances. This system adopts advanced measuring method and expert circuit. As the measure and the control core, the single chip processor is used. This system has wide frequency range and wide impedance testing range, much more adapted objects, and it is dependable, more precise and intelligent. The application of this system in practical testing has obtained optimal results.

Surface structural change of bioactive inorganic filler-resin composite cement in simulated body fluid: effect of resin.

Recently much attention has been paid to bioactive filler-resin composite cements because they can solidify in a few minutes to give high mechanical strengths and they can bond to living bone. In this study the dependence on resin of apatite-forming ability in simulated body fluid (SBF) was investigated for the composite cements of bioactive CaO-SiO2-P2O5-CaF2 glass with polymethyl methacrylate (PMMA) or bisphenol-a-glycidyl methacrylate/triethyleneglycol (Bis-GMA/TEGDMA) resin. The PMMA-containing composite cement did not show the apatite-forming ability in SBF because the reaction of the glass grains with SBF was inhibited due to the complete covering of the grains with PMMA. To the contrary, the Bis-GMA/TEGDMA-containing cement exhibited high apatite-forming ability in SBF; these monomers significantly dissolved from the composite surface into SBF, causing a direct exposure of the glass grains to SBF to convert into silica gel. It is assumed that thus formed silica gels, and the silicate ions that were dissolved and adsorbed onto the composite surface, induced the apatite nucleation between the spaces of the glass grains and on the composite surface, respectively. A continuous bone-like apatite layer was formed on the top surface of the glass-Bis-GMA/TEGDMA composite cement in a short period.

Trace elements in body fluids: external quality assessment scheme in The Netherlands.

External quality assessment schemes (EQAS) for trace elements in body fluids are organized in The Netherlands by the SKZL (Foundation for Quality Assessment in Clinical Laboratories). Medical laboratories participate on a voluntary base. The EQAS is designed to evaluate laboratory performance in terms of accuracy, precision and linearity. Laboratory-made frozen samples of whole blood, serum and urine, enriched with the elements of interest, i.e. Tl, Cd, Co, Hg, Se, Pb, Mg, Li, Al, Cu, Zn and As, are used. The present state of art shows an acceptable mean recovery, intra-laboratory variation and linearity. Interlaboratory variation, comparability of reference ranges and criteria of interpretation used in different laboratories are less satisfying and require improvement.

Minimally invasive sampling of transdermal body fluid for the purpose of measuring insulin-like growth factor-I during exercise training.

Insulin-like growth factor-I (IGF-I) is a ubiquitous hormone that is secreted in both an endocrine and an autocrine/paracrine manner. IGF-I has conventionally been measured in serum; however, transdermal body fluid (TDF) remains as an unexplored biocompartment in which IGF-I also resides and may be more biologically relevant because of its proximity to tissues and cells. The purpose of this study was to compare IGF-I in serum versus IGF-I in TDF before and after 8 weeks of physical training. Twenty-eight healthy men (28 +/- 5 years old, 176 +/- 8 cm tall, weighing 83 +/- 11 kg) had TDF obtained by a novel, minimally invasive method that included the application of continuous vacuum pressure on forearm skin perforated with tiny micropores created by a focused beam from a laser system and also had blood obtained by venipuncture. An enzyme-linked immunosorbent assay measured total IGF-I concentrations. A repeated-measures analysis of variance (biocompartment x time) and Pearson Product Moment Correlation coefficients (P < or = 0.05) were used for statistical analyses. Data are presented as mean +/- SE. Total TDF IGF-I was significantly lower than serum IGF-I both before (TDF, 91 +/- 6 ng/mL; serum, 375 +/- 17 ng/mL) and after (TDF, 83 +/- 5 ng/mL; serum, 363 +/- 19 ng/mL) the exercise training. Serum and TDF IGF-I values were not significantly different pre- to post-training. Serum and TDF IGF-I levels were significantly correlated pre-training (r = 0.41), but not post-training (r = 0.34). The percent change between serum and TDF was not correlated (r = 0.09). This study has demonstrated that total IGF-I can be sampled and measured in TDF via a minimally invasive manner and is appreciably (approximately 76%) less than total IGF-I measured in serum. Additionally, the IGF-I measurements in these two biocompartments were not closely associated, possibly indicating an uncoupled, rather than a linked, regulation of IGF-I among the body's biocompartments.

Body fluid homeostasis in the newborn infant with congestive heart failure: effects of diuretics.

Congestive heart failure is characterized by extracellular fluid volume expansion, increased venous filling pressure, and paradoxal renal sodium retention. Although diuretics remain invaluable agents to lower venous pressure in congestive heart failure, they also carry the risk of further compromising cardiac output and inducing severe adverse effects. This article reviews the pathophysiology of body fluid homeostasis in neonates with congestive heart failure, and discusses the adverse effects associated with the use and abuse of diuretics.
