Effect of portal-systemic anastomosis on renal haemodynamics in cirrhosis. (1/455)

In 12 patients with portal hypertension and repeated bleedings from oesophageal varices the central haemodynamics, portal pressure, and mean renal blood flow (RBF) were investigated immediately before and two to seven months after portal-systemic shunt. Cardiac output increased significantly, whereas arterial pressure was unchanged after operation. RBF, which was initially less than in controls, did not change. As portal pressure decreased significantly, a direct portal-renal, neural, or humoral reflex mechanism does not explain the subnormal RBF in cirrhosis. As plasma volume was large and unchanged after operation a "diminished circulating plasma volume" is an unlikely explanation. Therefore, on the basis of the present observations, previously postulated causes of renal hypoperfusion in cirrhosis need revision.  (+info)

Changes in haematological parameters and iron metabolism associated with a 1600 kilometre ultramarathon. (2/455)

OBJECTIVE: To investigate haematological variations and iron related changes in the serum of participants in a 1600 kilometre ultramarathon run. PARTICIPANTS: Seven male and two female participants in a 1600 km foot race. METHODS: Blood samples were obtained from the participants before, after four and 11 days of running, and at the end of the event. Samples were analysed by standard methods for haemoglobin, packed cell volume, total red cell count, mean red cell volume, mean red cell haemoglobin, total white cell count and differential, platelets, reticulocytes, iron, ferritin, total iron binding capacity, percentage transferrin saturation, haptoglobin, and bilirubin and corrected for changes in plasma volume. RESULTS: The following variables decreased during the event (p < 0.05): haemoglobin, packed cell volume, mean red cell volume, percentage lymphocytes, percentage monocytes, serum iron, total iron binding capacity, and percentage transferrin saturation. Increases (p < 0.05) were found in plasma volume, total red cell count (day 4 only), total white cell count, percentage and absolute numbers of neutrophils and reticulocytes, absolute numbers of lymphocytes and monocytes (day 4 only), absolute numbers of eosinophils (day 11 and race end), absolute numbers of basophils (race end only), platelets, ferritin, haptoglobin, and bilirubin (day 4 only). CONCLUSION: Ultramarathon running is associated with a wide range of changes in haematological parameters, many of which are related to the normal acute phase response to injury. These should not be confused with indicators of disease.  (+info)

Evaluation of pulmonary volumetric morphometry at the light and electron microscopy level in several species of passerine birds. (3/455)

The lungs of 3 small passerine species, having similar body mass but different diurnal activity patterns, were analysed morphometrically to assess the relationship between diurnal activity and pulmonary volumetry at the light and electron microscope levels. The percentage volumes of the major lung and exchange tissue components of the 3 species--an aerial insectivore, a foliage gleaner/nectarivore and a ground forager--were strikingly similar, and consistent with literature values for other passerine species. The only significant difference found was exchange tissue plasma volume and pulmonary haematocrit, with the ground-foraging, low activity Malurus splendens having significantly lower values than the other 2 species. This may indicate that cardiovascular parameters are more important determinants of metabolic activity in small passerines than aspects of pulmonary anatomy.  (+info)

Long-term effects of growth hormone (GH) on body fluid distribution in GH deficient adults: a four months double blind placebo controlled trial. (4/455)

OBJECTIVE: Short-term growth hormone (GH) treatment normalises body fluid distribution in adult GH deficient patients, but the impact of long-term treatment on body fluid homeostasis has hitherto not been thoroughly examined in placebo controlled trials. To investigate if the water retaining effect of GH persists for a longer time we examined the impact of 4 months GH treatment on extracellular volume (ECV) and plasma volume (PV) in GH deficient adults. DESIGN: Twenty-four (18 male, 6 female) adult GH deficient patients aged 25-64 years were included and received either GH (n=11) or placebo (n=13) in a double blind parallel design. METHODS: Before and at the end of each 4 month period ECV and PV were assessed directly using 82Br- and 125I-albumin respectively, and blood samples were obtained. RESULTS: During GH treatment ECV increased significantly (before: 20.48+/-0.99 l, 4 months: 23.77+/-1.38 l (P<0.01)), but remained unchanged during placebo administration (before: 16.92+/-1.01 l, 4 months: 17.60+/-1.24 l (P=0.37)). The difference between the groups was significant (P<0.05). GH treatment also increased PV (before: 3.39+/-0.27 l. 4 months: 3.71+/-0.261 (P=0.01)), although an insignificant increase in the placebo treated patients (before: 2.81+/-0.18 l, 4 months: 2.89+/-0.20 l (P=0.37)) resulted in an insignificant treatment effect (P=0.07). Serum insulin-like growth factor-I increased significantly during GH treatment and was not affected by placebo treatment. Plasma renin (mIU/l) increased during GH administration (before: 14.73+/-2.16, 4 months: 26.00+/-6.22 (P=0.03)) and remained unchanged following placebo (before: 20.77+/-5.13, 4 months: 20.69+/-6.67 (P=0.99)) leaving no significant treatment effect (P=0.08). CONCLUSION: The long-term impact of GH treatment on body fluid distribution in adult GH deficient patients involves expansion of ECV and probably also PV. These data substantiate the role of GH as a regulator of fluid homeostasis in adult GH deficiency.  (+info)

Increased orthostatic tolerance following moderate exercise training in patients with unexplained syncope. (5/455)

OBJECTIVE: To determine whether a programme of simple, moderate exercise training increases blood volume and improves orthostatic tolerance in patients with attacks of syncope or near syncope related to orthostatic stress. DESIGN: An open study in 14 patients referred with unexplained attacks of syncope, who were shown to have a low tolerance to an orthostatic stress test. Measurements were made of plasma and blood volumes, orthostatic tolerance to a test of combined head up tilt and lower body suction, and baroreceptor sensitivity by applying subatmospheric pressures to a chamber over the neck. Cardiorespiratory fitness was assessed from the relation between heart rate and oxygen uptake during a graded treadmill exercise test. Assessments were made before and after undertaking an exercise training programme (Canadian Air Force 5BX/XBX). RESULTS: After the training period, 12 of the 14 patients showed evidence of improved cardiorespiratory fitness. All 12 patients were symptomatically improved; they showed increases in plasma and blood volumes and in orthostatic tolerance, and decreases in baroreceptor sensitivity. Despite the improved orthostatic tolerance, values of blood pressure both while supine and initially following tilting were lower than before training. CONCLUSIONS: Exercise training has a role in the management of patients with syncope and poor orthostatic tolerance. It improves symptoms and increases orthostatic tolerance without increasing resting blood pressure.  (+info)

Mechanism for the posture-specific plasma volume increase after a single intense exercise protocol. (6/455)

To test the hypothesis that exercise-induced hypervolemia is a posture-dependent process, we measured plasma volume, plasma albumin content, and renal function in seven healthy subjects for 22 h after single upright (Up) or supine (Sup) intense (85% peak oxygen consumption rate) exercise. This posture was maintained for 5 h after exercise. Plasma volume decreased during exercise but returned to control levels by 5 h of recovery in both postures. By 22 h of recovery, plasma volume increased 2.4 +/- 0.8 ml/kg in Up but decreased 2.1 +/- 0.8 ml/kg in Sup. The plasma volume expansion in Up was accompanied by an increase in plasma albumin content (0.11 +/- 0.04 g/kg; P < 0.05). Plasma albumin content was unchanged in Sup. Urine volume and sodium clearance were lower in Up than Sup (P < 0.05) by 5 h of recovery. These data suggest that increased plasma albumin content contributes to the acute phase of exercise-induced hypervolemia. More importantly, the mechanism by which exercise influences the distribution of albumin between extra- and intravascular stores after exercise is altered by posture and is unknown. We speculate that factors associated with postural changes (e.g., central venous pressure) modify the increase in plasma albumin content and the plasma volume expansion after exercise.  (+info)

Effects of moderate exercise training on plasma volume, baroreceptor sensitivity and orthostatic tolerance in healthy subjects. (7/455)

The effect of physical training on an individual's ability to withstand an orthostatic stress is unclear. This study was undertaken to determine the effects on orthostatic tolerance in healthy volunteers of training at a level appropriate for unfit subjects and cardiorespiratory patients. In 11 asymptomatic, untrained subjects the following assessments were made: plasma volume by Evans Blue dye dilution and blood volume derived from haematocrit; carotid baroreceptor sensitivity from the slope of the regression of change in cardiac interval against pressure applied to a neck chamber; orthostatic tolerance as time to presyncope in a test of head-up tilting combined with lower body suction; exercise test relating heart rate to oxygen consumption. Subjects were then given a training schedule (5BX/XBX, Royal Canadian Air Force) involving 11-12 min of mixed exercises per day until an age/sex related 'target' was reached. Following training all subjects showed evidence of improved fitness, seen as decreases in heart rate at an oxygen uptake (Vo2) of 1.5 1 min-1 and in the elevation of the regression line between heart rate and Vo2. All also had increases in plasma and blood volumes and decreases in baroreceptor sensitivity. Seven of the subjects showed increases in orthostatic tolerance. Improvement in orthostatic tolerance was related to a low initial tolerance, and was associated with increases in plasma volume and decreases in baroreceptor sensitivity. These results show that moderate exercise training increases orthostatic tolerance in subjects who do not already have a high initial tolerance and suggest that training may be of value in the management of untrained patients with attacks of syncope due to orthostatic intolerance.  (+info)

Physical performance and associated electrolyte changes after haemoglobin normalization: a comparative study in haemodialysis patients. (8/455)

BACKGROUND: To determine the effects of different haemoglobin (Hb) levels on exercise performance and associated electrolyte changes, a prospective, randomized, double-blinded crossover study was completed in 14 haemodialysis patients. METHODS: Performance and changes in arterial [K+] and lactate were compared at rest and during a maximal incremental cycling exercise at a Hb concentration ([Hb]) of 10 g/dl ([Hb]10) and 14 g/dl ([Hb]14) following an initial baseline test (Hb: 8.3 +/- 0.2 g/dl, mean +/- SEM). Ages ranged from 23 to 65 years and patients were divided into younger (age 23-45 years, n = 9) and older (aged 55-65 years, n = 5) groups. RESULTS: Peak work rate and VO2 peak were higher at [Hb]14 than at [Hb]10. 145 +/- 9 vs 134 +/- 9 W, mu +/- SEM, P < 0.01, and 1.90 +/- 0.11 vs 1.61 +/- 0.11 l/min, P < 0.01, respectively. Improvements were demonstrated in both younger and older groups at the higher target [Hb], with an improved aerobic performance evident particularly in younger patients. However, performance remained below that predicted for comparable sedentary controls. Resting plasma [K+] was raised at both [Hb]10 and [Hb]14 compared with baseline (P < 0.01) although the change in [K+] from rest to peak exercise (delta[K+]) was similar at each level. The delta[K+] per unit work performed (used as a marker of K+ regulation) was, however, inversely related to the [Hb] (baseline: 80 +/- 12 micromol/l/kJ vs [Hb]10, 61 +/- 8, P < 0.01, vs [Hb]14. 49 +/- 7, P < 0.05). Exercise induced a significant but similar rise in lactate concentration at both target [Hb] (P < 0.001), which remained markedly elevated for at least 10 min after exercise in both younger and older groups. CONCLUSIONS: These data demonstrate that a physiological [Hb] improves, but does not normalize, exercise performance in end-stage renal failure. Both younger and older patients appear to benefit similarly from the enhanced oxygen transport. Impaired K+ regulation is apparently related to [Hb] and could well contribute to the observed limitations in performance.  (+info)

We investigated the effect of post-exercise sauna bathing on plasma volume (PV) expansion and whether such responses can be tracked by changes in heart rat
OBJECTIVE: To determine the degree of plasma volume expansion by 0.9% NaCl in relation to the infused volume, in sepsis/SIRS (systemic inflammatory response syndrome), after a standardized hemorrhage, and in a normal condition. DESIGN: Prospective, randomized animal study. SETTING: University hospital laboratory. SUBJECTS: Thirty anesthetized adult male rats. INTERVENTIONS: The study was performed in 3 groups: a sepsis/SIRS group (the S group), in which sepsis/SIRS was induced by cecal ligation and incision, a hemorrhage group (the H group), in which the rats were left without intervention for 4 hrs, and bled 8 mL/kg thereafter. The study also included a group that was left without intervention (the N group). Then, 4 hrs after baseline, all 3 groups were given an infusion of 0.9% NaCl (32 mL/kg) for 15 mins. Baseline was defined as the time point when the surgical preparation was finished. MEASUREMENTS AND MAIN RESULTS: Plasma volumes were measured using I-albumin dilution technique at baseline, ...
Abstract Blood volume studies were performed in 18 healthy men and 564 male patients with a variety of clinical diagnoses. Although the plasma volume measurements obtained with iodinated I 125 serum albumin were accurate in patients with erythrocytosis and in healthy patients, this method overestimated the plasma volume in patients with traumatic injuries, carcinoma, cardiopulmonary disorders, and miscellaneous diagnoses. However, in 47 patients with traumatic injuries, carcinoma, and miscellaneous diagnoses, cold agglutinin labeled with radioactive iodine (125I) gave an accurate measurement of plasma volume. These data demonstrate the limitations of the iodinated albumin molecule in measuring plasma volume and in indirectly estimating red blood cell (RBC) volume from the total body hematocrit value and the plasma volume as determined with iodinated I 125 serum albumin. The best method was by determining red blood cell volume with radioactive chromium (51Cr)-labeled RBC, and estimating plasma volume.
1. Plasma volume, packed cell volume (PCV), blood volume, extracellular fluid volume (ECFV) and Evans blue disappearance rate were measured in conscious spontaneously hypertensive rats and in weight-matched Wistar normotensive rats.. 2. Over the weight range studied (250-350 g), plasma and blood volumes were significantly lower in the spontaneously hypertensive rat. Extracellular fluid volumes were similar in the two groups.

SUMMARY Normal pregnancy involves many changes in maternal physiology, including alterations in hematologic parameters. These changes include expansion in maternal plasma volume. The increase in plasma volume is relatively larger than the increase in red cell mass resulting in a decrease in hemoglobin concentration. An increase in the levels of some plasma proteins alters the balance of coagulation and fibrinolysis. Worldwide, the predominant cause of anemia in pregnancy is iron deficiency. Fetal requirements for iron are met despite maternal deficiency, but maternal iron deficiency has a number of adverse consequences including an increased frequency of preterm delivery and low-birth-weight infants. Bleeding disorders in pregnancy are a common reason for hematologic consultation and evoke concern for both the mother and child. Life-threatening bleeding caused by disseminated intravascular coagulation is seen with some complications unique to pregnancy, including placental abruption, retained ...

Hemodilution of the plasma by more than 20% associated with priming cardiopulmonary bypass pumps, plasma volume expansion or other fluid administration therapies using certain solutions may cause clinically significant error on ionized calcium results. These errors are associated with solutions that do not match the ionic characteristics of plasma. To avoid these errors when hemodiluting by more than 20%, use physiologically balanced multi-electrolyte solutions containing low-mobility anions (e.g. Gluconate) such as Normosol-R (Abbott Laboratories), Plasma-Lyte-A (Baxter Healthcare oCrporation), and Isolyte-S (B Braun Medical) rather than solutions such as normal saline or ringers lactate.. ...

The plasma volume constitutes one fourth of the total extracellular fluid volumeThe total extracellular fluid volume represents 20% of body weight. The plasma volume is approximately 5% of body weight. Sodium is the principal cation. The Gibbs-Donan equilibrium equation explains the higher total concentration of cations in plasma. Except for joint fluid and cerebrospinal fluid, the majority of the interstitial fluid exists as a rapidly equilibrating component. - ProProfs Discuss

Previous studies have suggested a range of therapies for POTS, including mineralocorticoids, combined with increased salt and water intake to enhance plasma volume and use of adrenoceptor agonists such as minodrine however these agents often have side effects and may be ineffective in a significant number of patients. Exercise regimens offer little in the way of harm, and if ,as this research suggests, exercise offers significant benefits then perhaps it should be tried initially and potentially as an adjunct for all POTS patients ...

ABSTRACT Hypervolemia is a hallmark of endurance training (ET) and manifests by similar elevations in plasma (PV) and red blood cell volume (RBCV) so that hematocrit largely remains unaltered following weeks/months of training

Introduction- Exercise-induced plasma volume (PV) expansion is typically associated with an increase in plasma albumin content. Increased hepatic albumin synthesis, a transcriptionally regulated process, is thought to contribute to the increase in albumin content. Objective- We tested the hypothesis that exercise training induces an increase in albumin gene expression in relationship to the increase in PV. Methods and Results- 40 adult male Sprague-Dawley rats weighing between 245-350 grams were randomly assigned to one of four groups: cage control (CC); sham exercise 10 min/day at 48% VO2max (NE); continuous exercise training, 60 min /day at 72% VO2max (LI); and high intensity, intermittent exercise training, 8 bouts of 4 min at 98% VO2max followed by 5 min at 48% VO2max (HI). The training period lasted for two weeks with 12 training sessions with equalized training volumes in the exercise groups. 24 hours after the last training session the rats were anesthetized and a jugular catheter was placed for
Heat acclimation is associated with plasma volume (PV) expansion that occurs within the first week of exposure. However, prolonged effects on hemoglobin mass (Hbmass) are unclear as intervention periods in previous studies have not allowed sufficient time for erythropoiesis to manifest. Therefore, Hbmass, intravascular volumes, and blood volume (BV)-regulating hormones were assessed with 5½ weeks of exercise-heat acclimation (HEAT) or matched training in cold conditions (CON) in 21 male cyclists [(mean ± SD) age: 38 ± 9 years, body weight: 80.4 ± 7.9 kg, VO2peak: 59.1 ± 5.2 ml/min/kg]. HEAT (n = 12) consisted of 1 h cycling at 60% VO2peak in 40°C for 5 days/week in addition to regular training, whereas CON (n = 9) trained exclusively in cold conditions (,15°C). Before and after the intervention, Hbmass and intravascular volumes were assessed by carbon monoxide rebreathing, while reticulocyte count and BV-regulating hormones were measured before, after 2 weeks and post intervention. Total ...
Despite significant technical improvements (bicarbonate dialysate, volumetric ultrafiltration control) high intradialytic ultrafiltration is troublesome in children, specially in the proportion of patients presenting a normal or low blood pressure even with overweight. We used, in this group of children (overhydratated without vascular repercution) a modelling of both sodium and ultrafiltration during dialysis, in order to achieve dry body weight without increasing session time despite hypotension risks. The usefulness and practicability of sodium and ultrafiltration modelling together during dialysis in children is analysed in a short time study (for plasma volume changes calculation) and in a long term follow up study over a year (for clinical tolerance ...
This study aimed to examine a wide profile of acute biochemical and neuromuscular responses to strength (STR) and hypertrophy (HYP) resistance exercise (RE). Seven trained men completed an STR workout (4 × 6 repetitions, 85% 1 repetition maximum [1RM], 5-minute rest periods), an HYP workout (4 × 10 repetitions, 70% 1RM, 90-second rest periods), and a control condition (CON) in a randomized crossover design. Peak force (PF), rate of force development (RFD), and muscle activity were quantified before and after exercise during an isometric squat protocol. Blood samples were taken 20, 10, and 0 minutes before and 0, 10, and 60 minutes after exercise to measure the concentration of blood lactate (BL), pH, and a number of electrolytes that were corrected for plasma volume changes. No differences were observed between the workouts for changes in PF, RFD, or muscle activity. Repeated contrasts revealed a greater (p ≤ 0.05) increase in BL concentration and reduction in pH after the HYP protocol than ...
Atrial natriuretic peptide (ANP) acts acutely to reduce plasma volume by at least 3 mechanisms: increased renal excretion of salt and water, vasodilation, and increased vascular permeability. Authors of a study in this issue of the JCI performed a knockout of the receptor for ANP in vascular endothelia in order to distinguish the effects of ANP-dependent increases in vascular permeability from those of other endocrine actions of ANP in the regulation of plasma volume. The knockout mice exhibited reduced vascular permeability to plasma protein, resulting in chronically increased plasma volume, arterial hypertension, and cardiac hypertrophy. Renal excretion and vasodilation did not account for these changes. Thus ANP-induced increases in endothelial permeability may be critical to the ability of ANP to lower arterial blood pressure.. ...
Venous stasis (prolonged tourniquet application) and forearm exercise may increase ionized calcium due to a decrease in pH caused by localized production of lactic acid. Exposing the sample to air will cause an increase in pH due to the loss of CO2, which will decrease ionized calcium.. Heparin binds calcium. Each unit of heparin added per ml of blood will decrease ionized calcium by 0.01 mmol/L. Therefore, the correct ratio of heparin anticoagulant to blood must be achieved during sample collection. Intravenous injection of 10,000 units of heparin has been shown in adults to cause a significant decrease of ionized calcium of about 0.03 mmol/L.. Hemodilution of the plasma by more than 20% associated with priming cardiopulmonary bypass pumps, plasma volume expansion or other fluid administration therapies using certain solutions may cause clinically significant error on ionized calcium results. These errors are associated with solutions that do not match the ionic characteristics of plasma. To ...
Early fluid replacement and plasma volume expansion in the adjunctive treatment of certain types of shock or impending shock (e.g., burns, surgery, hemorrhage,
These results demonstrate that splenectomy is able to blunt the decline in MAP, the increase in hematocrit, and the reduction in plasma volume that is observed in intact animals infused with a low dose of LPS. It is important to emphasize that the increase in hematocrit observed in the intact animals results from the reduction in plasma volume (Fig. 3) not from splenic contraction and discharge of high hematocrit blood into the circulation. The rat spleen neither is contractile nor does it have storage capacity (32). Moreover, we have previously demonstrated that within the intrasplenic circulation there appears to be a mechanism enabling the efflux of iso-oncotic fluid from the blood into the lymphatic system (24). We propose therefore that during endotoxemia this fluid efflux is exaggerated, resulting in hemoconcentration and hypotension. The second experiment (Study B) supports this suggestion. Despite the initial fall in blood pressure caused by LPS, splenic arterial flow was maintained due ...

The model: While Ill leave it to you to check out the full supplemental information for the details of their model, it is firmly rooted in the quantitative genetics framework of Lande land (Lande 1979; Lande and Arnold, 1983). As such, evolutionary change is measured by how selection changes the variance/covariance structure (G-matrix) of the underlying traits. The analytical model assumes a fixed G-matrix, however their simulations relax this assumption. The primary goal of the analysis is to calculate the ability of the victim/host to escape the exploiter/parasite measured as the maximum evolutionary escape rate. This evolutionary escape rate is the difference in the rates of change of the host defense traits compared to the parasite attacking trait. When the host is winning host it is said to be outrunning the parasite ...
The concept here is to regularly submit your body to training in the heat prior to an expected hot race. Research shows this can be an effective strategy. Training in heat increases blood plasma volume over time and promotes other positive physiological adaptations to exercising in the heat. It is not a quick fix. Training in the heat the week before a race wont help. Adaptation occur over a 3-4 week time period. Sessions need not be longer than 100 minutes. Acclimation must be maintained otherwise the positive effects begin to diminish ...

The Volume Merge operation flattens the scalar data in a collection of volumes into a single base volume. This is useful for converting many overlapping volumes into one large volume for more efficient rendering. For example, you can stamp hundreds of thousands of volumes into a single volume for faster rendering, and flatten hierarchies into a low-res base. You can also create a Frustum volume that ensures only voxels in your cameras field of view are created.. ...

Modifications are described which make T-1824 suitable for plasma volume determinations on small bats. An average plasma volume of 6.5 ml/100 gm body weight has been determined for the active little brown bat, Myotis lucifugus; average blood volume, based on plasma volume and hematocrit, is 13.0 ml/100 gm body weight. Seasonal changes have been observed which apparently result primarily from changes in lean body weight and from pregnancy. Young bats have a proportionately greater blood volume. No significant differences have been found between sexes, nor between determinations made during day and night hours. Plasma and blood levels are changing least at the beginning and end of the hibernating period. Comparisons of previous studies suggest that, while a plasma decrease and unchanged cell volume seem generally characteristic of mammals which have entered hibernation, a concurrent drop in heart blood hematocrit of the hibernating bat suggests a redistribution of erythrocytes as well.. ...
Large volume paracentesis is an effective treatment for refractory ascites. The need for plasma volume expansion after paracentesis is controversial. Some studies have failed to demonstrate any disturbances in systemic or renal haemodynamics 48 hours after a single 5 litre paracentesis.5 14 However, other studies have highlighted the potential harmful effects on circulatory homeostasis after massive paracentesis in patients with tense ascites when performed without simultaneous plasma volume expansion.1 2 The pathogenesis of PCD remains incompletely understood. Recently, Ruiz del Arbolet al showed that the degree of activation of the renin-angiotensin system and sympathetic nervous system six days after paracentesis correlated inversely with changes in SVR.13 This finding suggests that accentuation of the peripheral arterial vasodilatation of cirrhosis occurs sometime after massive paracentesis. Similar results were observed in a recently published study14 showing that the increase in PRA and ...

Self-reported URTS were also recorded for 14 days after the race. ECP was measured using radioimmunoassay and IgE using the Alastat Microplate Total IgE kit. The after-exercise values were corrected for plasma volume changes, which were calculated from haematocrit and haemoglobin values. Serum concentrations of ECP and IgE were analysed using an analysis of variance (ANOVA) comparing values with
The two main mechanisms of ascites formation in cirrhosis are universal: portal (sinusoidal) hypertension and renal retention of sodium. In cirrhosis, fluid extravasates from the hepatic sinusoids rather than from the splanchnic capillaries. Therefore, leakage of fluid into the peritoneal space occurs as a result of sinusoidal hypertension that in turn results from hepatic venous outflow block secondary to regenerative nodules and fibrosis. However, sinusoidal hypertension alone is not sufficient for the continuous formation of ascites. Plasma volume expansion, through sodium and water retention, allows for the replenishment of the intravascular volume and is the other essential factor in the pathogenesis of cirrhotic ascites. As mentioned above, as portal pressure increases (and collaterals form), there is concomitant arterial splanchnic and systemic vasodilatation that results in a reduction in the effective arterial blood volume.19 This underfilling leads to baroreceptor stimulation and ...
The endothelial glycocalyx has been particularly difficult to characterize and understand in terms of its three-dimensional structure because of its fragility and instability [1]. Indeed, in addition to trauma, surgery, hyperglycemia, and sepsis, even subtle stimuli such as a plasma volume expansion can disrupt the glycocalyx structure [20, 23-27]. Disruption of glycocalyx exposes the endothelial cells to oxidative damage, and vascular hyperpermeability is observed in sepsis and chronic conditions such as diabetes and hypertension [5, 28]. There has been much effort to visualize endothelial glycocalyx using TEM and substitution of the original ruthenium red staining with lanthanum or alcian blue [7, 29, 30]. In the present study, we adopted lanthanum nitrate staining with a careful perfusion method that entailed (1) incision in the right atrial appendage to relieve pressure during perfusion fixation; (2) neck ligation for better perfusion of the heart, kidney, and liver; and (3) use of a ...
Cardiovascular risk factors and markers of endothelial cell function were studied in nondiabetic patients with mild to moderate chronic renal failure. The transcapillary escape rate of albumin and the plasma concentrations of von Willebrand factor, fibrinogen, and plasma lipids were measured in 29 nondiabetic patients (GFR of 25 (11-44) mL/min x 1.73 m2 (median and range)) and 14 normal subjects. The proportion of smokers was similar between the groups. In the patients, the plasma concentration of von Willebrand factor was elevated by 61% (1.27 +/- 0.44 versus 0.79 +/- 0.28 U/mL; P , 0.01) (mean +/- SD) and that of fibrinogen was elevated by 72% (10.18 +/- 4.14 versus 5.92 +/- 2.01 mumol/L; P , 0.01). The plasma concentrations of lipoproteins showed an atherogenic pattern in the patients with increased levels of very low-density lipoprotein cholesterol (0.57 +/- 0.31 versus 0.33 +/- 0.13 mmol/L; P , 0.01) and triglycerides (1.26 +/- 0.25 versus 0.71 +/- 0.28 mmol/L; P , 0.01), but a decreased ...

There is no objective evidence of how long intravenous solutions remain inside venous blood vessels after they have been administered, therefore there is no definite guideline of how to administer them in the preoperative setting. Besides, obese patients represent a particular group of subjects as they theoretically with-hold a constant inflammatory response and that would modify the way solutions behave intravenously, that is how long they remain inside.. Having said this, we wish to describe the way colloid solutions behave in this group of patients by taking serial blood samples in 12 obese patients after a colloid infusion, to calculate plasma dilution curves based on hemoglobin dilution and therefore infer the time it remains intravascularly.. All this in the hope this information will help, in the near future, to establish a more objective way to use these solutions and avoid possible complications due to over-administration. ...

Injection of a high density plasma into a magnetic mirror was accomplished by generating plasma vortex rings under both mirror coils. Observations indicated that the rings move toward the center of the mirror and collide. Trapped magnetic fields in the rings produced a field reversal at the center of the mirror. The collision was followed by an oscillating motion of the ring currents flowing in the highly ionized plasma. Plasma was trapped inside the mirror for times of the order of milli-seconds. There was no recycling of the gas in the mirror system. The plasma thermalized and then left through the escape cones and by diffusion to the walls. The ion temperature was of the order of 200 eV. Plasma volume was approximately 1000cc. Confining field was 10kG. Author
Dear Barbara, This is a very interesting question! Here are some considerations I made in calculating the number of calories in a pint of blood. The strategy is to express the components of blood in terms of grams of protein, lipid and carbohydrate. Then convert the grams to calories. An alternative and more direct way of determining the number of calories in a donated pint of blood would be to dry it down (to remove the water), and then burn it in a calorimeter to calculate how much heat is generated from the blood. I can calculate a reasonable number for calories associated with the plasma (non-cellular portion) of the blood, but I can only make a rough approximation of the calories obtained from the red blood cells. 1. A blood donation usually is 400 to 495 ml (for calculations I will use 500 ml). 2. Assume an average hematocrit of 40% for a woman (40% red blood cells, 60% plasma by volume). 500 ml x 40% = 200 ml (plasma volume) *Plasma glucose: The average plasma glucose concentration is 90 ...
