Quantifying the effect of changes in the hemodialysis prescription on effective solute removal with a mathematical model. (1/173)
One potential benefit of chronic hemodialysis (HD) regimens of longer duration or greater frequency than typical three-times-weekly schedules is enhanced solute removal over a relatively wide molecular weight spectrum of uremic toxins. This study assesses the effect of variations in HD frequency (F: per week), duration (T: min per treatment), and blood/dialysate flow rates (QB/QD: ml/min) on steady-state concentration profiles of five surrogates: urea (U), creatinine (Cr), vancomycin (V), inulin (I), and beta2-microglobulin (beta2M). The regimens assessed for an anephric 70-kg patient were: A (standard): F = 3, T = 240, QB = 350, QD = 600; B (daily/short-time): F = 7, T = 100, QB = 350, QD = 600; C/D/E (low-flow/long-time): F = 3/5/7, T = 480, QB = 300, QD = 100. HD was simulated with a variable-volume double-pool model, which was solved by numerical integration (Runge-Kutta method). Endogenous generation rates (G) for U, Cr, and beta2M were 6.25, 1.0, and 0.17 mg/min, respectively; constant infusion rates for V and I of 0.2 and 0.3 mg/min, respectively, were used to simulate middle molecule (MM) G values. Intercompartment clearances of 600, 275, 125, 90, and 40 ml/min were used for U, Cr, V, I, and beta2M, respectively, For each solute/regimen combination, the equivalent renal clearance (EKR: ml/min) was calculated as a dimensionless value normalized to the regimen A EKR, which was 13.4, 10.8, 6.6, 3.7, and 4.8 ml/min for U, Cr, V, I, and beta2M, respectively. For regimens B, C, D, and E, respectively, these normalized EKR values were U: 1.04, 0.96, 1.58, and 2.22; Cr: 1.03, 1.08, 1.80, and 2.55; V: 1.06, 1.32, 2.21, and 3.12; I: 1.05, 1.54, 2.57, and 3.62; beta2M: 1.00, 1.27, 1.73, and 2.19. The extent of post-HD rebound (%) was highest for regimens A and B, ranging from 16% (urea) to 50% (inulin), and lowest for regimen E, ranging from 6% (urea) to 28% (beta2M). The following conclusions can be made: (1) Relative to a standard three-times-weekly HD regimen of approximately the same total (weekly) treatment duration, a daily/short-time regimen results in modest (3 to 6%) increases in effective small solute and MM removal. (2) Relative to a standard three-times-weekly HD regimen, a three-times-weekly low-flow/long-time regimen results in comparable effective small solute removal and progressive increases in MM and beta2M removal. A daily low-flow/long-time regimen substantially increases the effective removal of all solutes. (+info)Pharmacokinetics of new calcium channel antagonist clevidipine in the rat, rabbit, and dog and pharmacokinetic/pharmacodynamic relationship in anesthetized dogs. (2/173)
Clevidipine is a new vascular selective calcium channel antagonist of the dihydropyridine type, structurally related to felodipine. Clinical trials have shown that the drug can be used to effectively control the blood pressure in connection with cardiac surgical procedures. The compound is tailored to be a short-acting drug and, due to incorporation of an ester linkage into the drug molecule, clevidipine is rapidly metabolized by ester hydrolysis. The pharmacokinetics of clevidipine and its primary metabolite, H 152/81, were studied in rats, rabbits, and dogs. In addition, the influence of the pharmacokinetics on the effect on mean arterial blood pressure was evaluated in anesthetized dogs. Compartmental nonlinear mixed effect regression analysis was used to calculate the population mean and individual pharmacokinetics of clevidipine, whereas nonlinear regression analysis of individual data was used to determine the pharmacokinetics of the primary metabolite. A linked Emax model was fitted to the individual pharmacodynamic/pharmacokinetic data in dogs. According to the results, clevidipine is a high-clearance drug with a relatively small volume of distribution, resulting in an extremely short half-life in all species studied. The median initial half-life of the individual value (Bayesian estimates) is 12, 20, and 22 s in the rabbit, rat, and dog, respectively. The primary metabolite is a high-clearance compound in the dog, whereas it is a low-clearance compound in the rat. A significant gender difference in the clearance of the metabolite was observed in the rat. The mean maximum reduction in arterial blood pressure is 38 +/- 12% (Emax) and is achieved at 85 +/- 46 nM (EC50). The half-life for reaching equilibrium between the central and the effect compartment (T1/2ke0) is 47 +/- 49 s. (+info)Which linear compartmental systems can be analyzed by spectral analysis of PET output data summed over all compartments? (3/173)
General linear time-invariant compartmental systems were examined to determine which systems meet the conditions necessary for application of the spectral analysis technique to the sum of the concentrations in all compartments. Spectral analysis can be used to characterize the reversible and irreversible components of the system and to estimate the minimum number of compartments, but it applies only to systems in which the measured data can be expressed as a positively weighted sum of convolution integrals of the input function with an exponential function that has real-valued nonpositive decay constants. The conditions are met by compartmental systems that are strongly connected, have exchange of material with the environment confined to a single compartment, and do not contain cycles, i.e., there is no possibility for material to pass from one compartment through two or more compartments back to the initial compartment. Certain noncyclic systems with traps, systems with cycles that obey a specified loop condition, and noninterconnected collections of such systems also meet the conditions. Dynamic positron emission tomographic data obtained after injection of a radiotracer, the kinetics of which can be described by any model in the class of models identified here, can be appropriately analyzed with the spectral analysis technique. (+info)Single- and multifrequency models for bioelectrical impedance analysis of body water compartments. (4/173)
The 1994 National Institutes of Health Technology Conference on bioelectrical impedance analysis (BIA) did not support the use of BIA under conditions that alter the normal relationship between the extracellular (ECW) and intracellular water (ICW) compartments. To extend applications of BIA to these populations, we investigated the accuracy and precision of seven previously published BIA models for the measurement of change in body water compartmentalization among individuals infused with lactated Ringer solution or administered a diuretic agent. Results were compared with dilution by using deuterium oxide and bromide combined with short-term changes of body weight. BIA, with use of proximal, tetrapolar electrodes, was measured from 5 to 500 kHz, including 50 kHz. Single-frequency, 50-kHz models did not accurately predict change in total body water, but the 50-kHz parallel model did accurately measure changes in ICW. The only model that accurately predicted change in ECW, ICW, and total body water was the 0/infinity-kHz parallel (Cole-Cole) multifrequency model. Use of the Hanai correction for mixing was less accurate. We conclude that the multifrequency Cole-Cole model is superior under conditions in which body water compartmentalization is altered from the normal state. (+info)Isotope dilution spaces of mice injected simultaneously with deuterium, tritium and oxygen-18. (5/173)
The isotope dilution technique for measuring total body water (TBW), and the doubly labelled water (DLW) method for measuring energy expenditure, are both sensitive to small variations in the ratio of the hydrogen to oxygen-18 dilution space. Since the dilution space ratio varies between individuals, there has been much recent debate over what causes this variability (i.e. physiological differences between individuals or analytical error in the isotope determinations), and thus which values (individual or a population mean dilution space ratio) should be employed for TBW and DLW calculations. To distinguish between physiological and analytical variability, we injected 15 non-reproductive and 12 lactating mice (Mus musculus, outbred MF1) simultaneously with deuterium, tritium and oxygen-18. The two hydrogen labels were administered and analysed independently, therefore we expected a strong correlation between dilution space ratios based on deuterium and tritium if most of the variation in dilution spaces was physiological, but only a weak correlation if most of the variation was analytical. Dilution spaces were significantly influenced by reproductive status. Dilution spaces expressed as a percentage of body mass averaged 15.7 % greater in lactating mice than in non-reproductive mice. In addition, the hydrogen tracer employed had a significant effect (deuterium spaces were 2.0 % larger than tritium spaces). Deuterium and tritium dilution spaces, expressed as a percentage of body mass, were highly correlated. Dilution space ratios ranged from 0.952 to 1. 146 when using deuterium, and from 0.930 to 1.103 when using tritium. Dilution space ratios based on deuterium and tritium were also highly correlated. Comparison of standard deviations of the dilution space ratio based on deuterium in vivo and in vitro indicated that only 4.5 % of the variation in the dilution space ratios observed in the mice could be accounted for by analytical variation in the deuterium and oxygen-18 analyses. Although our results include data which were outside the limits previously regarded as biologically possible, the correlations that we detected strongly suggest that variation in the observed dilution space ratio was mostly physiological rather than analytical. (+info)Effect of epinephrine on lidocaine clearance in vivo: a microdialysis study in humans. (6/173)
BACKGROUND: Local anesthetic nerve block prolonged by epinephrine is thought to result from local vasoconstriction and consequent decreased local anesthetic clearance from the injection site. However, no study has yet confirmed this directly in humans by measuring tissue concentrations of local anesthetic over time. In addition, recent studies have shown that the alpha2-adrenergic receptor agonist, clonidine, also prolongs nerve block without altering local anesthetic clearance. Because epinephrine is also an alpha2-adrenergic receptor agonist, it is possible that epinephrine prolongs local anesthetic block by a pharmacodynamic mechanism and not a pharmacokinetic one. This study was designed to address this issue. METHODS: Microdialysis probes were placed adjacent to the superficial peroneal nerve in both feet of eight volunteers. Plain lidocaine (1%) was injected along one peroneal nerve and lidocaine with epinephrine (2.5 microg/ml) was injected along the other nerve in a double-blinded, randomized manner. The concentration of lidocaine in tissue was measured at 5-min intervals, and sensory block and cutaneous blood flow were assessed by laser Doppler at 10-min intervals for 5 h. The resulting data for lidocaine concentration versus time were fit to a two-compartment model using modeling software. RESULTS: Epinephrine prolonged sensory block by decreasing local blood flow and slowing clearance. There was no evidence of a pharmacodynamic effect of epinephrine. CONCLUSION: Although epinephrine activates alpha2-adrenergic receptors, its mechanism for prolonging the duration of local anesthetic block rests on its ability to decrease local anesthetic clearance and not on a pharmacodynamically mediated potentiation of local anesthetic effect. (+info)Water diffusion, T(2), and compartmentation in frog sciatic nerve. (7/173)
A potential relationship between structural compartments in neural tissue and NMR parameters may increase the specificity of MRI in diagnosing diseases. Nevertheless, our understanding of MR of nerves and white matter is limited, particularly the influence of various water compartments on the MR signal is not known. In this study, components of the (1)H transverse relaxation decay curve in frog peripheral nerve were correlated with the diffusion characteristics of the water in the nerve. Three T(2) values were identified with nerve. Water mobility was found to be unrestricted on the timescale of 100 msec in the component of the signal with the intermediate T(2) time, suggesting some contribution from the interstitial space to this T(2) component. Restricted diffusion was observed in the component with the longest T(2) time, supporting the assignment of at least part of the spins contributing to this component to an intracellular compartment. The observed nonexponential behavior of the diffusion attenuation curves was investigated and shown to be potentially caused by the wide range of axon sizes in the nerve. Magn Reson Med 42:911-918, 1999. (+info)Physiologically based toxicokinetic modeling of inhaled ethyl tertiary-butyl ether in humans. (8/173)
A physiologically based toxicokinetic (PBTK) model was developed for evaluation of inhalation exposure in humans to the gasoline additive, ethyl tertiary-butyl ether (ETBE). PBTK models are useful tools to relate external exposure to internal doses and biological markers of exposure in humans. To describe the kinetics of ETBE, the following compartments were used: lungs (including arterial blood), liver, fat, rapidly perfused tissues, resting muscles, and working muscles. The same set of compartments and, in addition, a urinary excretion compartment were used for the metabolite tertiary-butyl alcohol (TBA). First order metabolism was assumed in the model, since linear kinetics has been shown experimentally in humans after inhalation exposure up to 50 ppm ETBE. Organ volumes and blood flows were calculated from individual body composition based on published equations, and tissue/blood partition coefficients were calculated from liquid/air partition coefficients and tissue composition. Estimates of individual metabolite parameters of 8 subjects were obtained by fitting the PBTK model to experimental data from humans (5, 25, 50 ppm ETBE, 2-h exposure; Nihlen et al., Toxicol. Sci., 1998; 46, 1-10). The PBTK model was then used to predict levels of the biomarkers ETBE and TBA in blood, urine, and exhaled air after various scenarios, such as prolonged exposure, fluctuating exposure, and exposure during physical activity. In addition, the interindividual variability in biomarker levels was predicted, in the eight experimentally exposed subjects after a working week. According to the model, raising the work load from rest to heavy exercise increases all biomarker levels by approximately 2-fold at the end of the work shift, and by 3-fold the next morning. A small accumulation of all biomarkers was seen during one week of simulated exposure. Further predictions suggested that the interindividual variability in biomarker levels would be higher the next morning than at the end of the work shift, and higher for TBA than for ETBE. Monte Carlo simulations were used to describe fluctuating exposure scenarios. These simulations suggest that ETBE levels in blood and exhaled air at the end of the working day are highly sensitive to exposure fluctuations, whereas ETBE levels the next morning and TBA in urine and blood are less sensitive. Considering these simulations, data from the previous toxicokinetic study and practical issues, we suggest that TBA in urine is a suitable biomarker for exposure to ETBE and gasoline vapor. (+info)Body fluid compartments refer to the distribution of body fluids in the human body, which are divided into two main compartments: the intracellular fluid compartment and the extracellular fluid compartment. The intracellular fluid compartment contains fluid that is inside the cells, while the extracellular fluid compartment contains fluid that is outside the cells.
The extracellular fluid compartment is further divided into two sub-compartments: the interstitial fluid compartment and the intravascular fluid compartment. The interstitial fluid compartment is the space between the cells, while the intravascular fluid compartment is the fluid inside the blood vessels.
These body fluid compartments are essential for maintaining homeostasis in the human body, as they help to regulate the balance of water and electrolytes, transport nutrients and waste products, and provide a medium for immune cells to travel through the body. Abnormalities in the distribution of body fluids can lead to various medical conditions, such as edema, dehydration, and heart failure.
An aortopulmonary septal defect, also known as a congenital heart defect, is a type of ventricular septal defect (VSD). It is a hole in the wall that separates the two lower chambers of the heart - the left and right ventricles. In an aortopulmonary septal defect, the hole is located in the part of the ventricular septum that is next to the pulmonary valve and the aortic valve. This defect allows oxygenated blood from the left ventricle to mix with deoxygenated blood from the right ventricle, resulting in inefficient oxygenation of the blood and increased workload on the heart.
The severity of an aortopulmonary septal defect can vary depending on the size of the hole and the presence of other cardiac abnormalities. Symptoms may include difficulty breathing, poor feeding, and failure to thrive in infants. If left untreated, this condition can lead to serious complications such as heart failure, pulmonary hypertension, and infective endocarditis. Treatment typically involves surgical closure of the defect, which is usually performed during the first year of life.
Body fluids refer to the various liquids that can be found within and circulating throughout the human body. These fluids include, but are not limited to:
1. Blood: A fluid that carries oxygen, nutrients, hormones, and waste products throughout the body via the cardiovascular system. It is composed of red and white blood cells suspended in plasma.
2. Lymph: A clear-to-white fluid that circulates through the lymphatic system, helping to remove waste products, bacteria, and damaged cells from tissues while also playing a crucial role in the immune system.
3. Interstitial fluid: Also known as tissue fluid or extracellular fluid, it is the fluid that surrounds the cells in the body's tissues, allowing for nutrient exchange and waste removal between cells and blood vessels.
4. Cerebrospinal fluid (CSF): A clear, colorless fluid that circulates around the brain and spinal cord, providing protection, cushioning, and nutrients to these delicate structures while also removing waste products.
5. Pleural fluid: A small amount of lubricating fluid found in the pleural space between the lungs and the chest wall, allowing for smooth movement during respiration.
6. Pericardial fluid: A small amount of lubricating fluid found within the pericardial sac surrounding the heart, reducing friction during heart contractions.
7. Synovial fluid: A viscous, lubricating fluid found in joint spaces, allowing for smooth movement and protecting the articular cartilage from wear and tear.
8. Urine: A waste product produced by the kidneys, consisting of water, urea, creatinine, and various ions, which is excreted through the urinary system.
9. Gastrointestinal secretions: Fluids produced by the digestive system, including saliva, gastric juice, bile, pancreatic juice, and intestinal secretions, which aid in digestion, absorption, and elimination of food particles.
10. Reproductive fluids: Secretions from the male (semen) and female (cervical mucus, vaginal lubrication) reproductive systems that facilitate fertilization and reproduction.
Body water refers to the total amount of water present in the human body. It is an essential component of life and makes up about 60-70% of an adult's body weight. Body water is distributed throughout various fluid compartments within the body, including intracellular fluid (water inside cells), extracellular fluid (water outside cells), and transcellular fluid (water found in specific bodily spaces such as the digestive tract, eyes, and joints). Maintaining proper hydration and balance of body water is crucial for various physiological processes, including temperature regulation, nutrient transportation, waste elimination, and overall health.
Extracellular fluid (ECF) is the fluid that exists outside of the cells in the body. It makes up about 20-25% of the total body weight in a healthy adult. ECF can be further divided into two main components: interstitial fluid and intravascular fluid.
Interstitial fluid is the fluid that surrounds the cells and fills the spaces between them. It provides nutrients to the cells, removes waste products, and helps maintain a balanced environment around the cells.
Intravascular fluid, also known as plasma, is the fluid component of blood that circulates in the blood vessels. It carries nutrients, hormones, and waste products throughout the body, and helps regulate temperature, pH, and osmotic pressure.
Maintaining the proper balance of ECF is essential for normal bodily functions. Disruptions in this balance can lead to various medical conditions, such as dehydration, edema, and heart failure.
The extracellular space is the region outside of cells within a tissue or organ, where various biological molecules and ions exist in a fluid medium. This space is filled with extracellular matrix (ECM), which includes proteins like collagen and elastin, glycoproteins, and proteoglycans that provide structural support and biochemical cues to surrounding cells. The ECM also contains various ions, nutrients, waste products, signaling molecules, and growth factors that play crucial roles in cell-cell communication, tissue homeostasis, and regulation of cell behavior. Additionally, the extracellular space includes the interstitial fluid, which is the fluid component of the ECM, and the lymphatic and vascular systems, through which cells exchange nutrients, waste products, and signaling molecules with the rest of the body. Overall, the extracellular space is a complex and dynamic microenvironment that plays essential roles in maintaining tissue structure, function, and homeostasis.
