Blood has a number of rheological properties which partially determine flow, especially at capillary level, and its capacity to deliver oxygen. It is non-Newtonian, pseudoplastic, thixotropic and viscoelastic. Viscosity can be studied with different types of viscosimeters (coaxial cylinder or capillary viscosimeters). It can be defined by the ratio of stress of deformation to rate of deformation. Viscosity depends on macrorheological parameters: hematocrit, serum proteins, especially fibrinogen and globulins, and also on microrheological parameters: degree of aggregation and red blood cell deformability. Viscosity rises when the temperature falls and decreases with the radius of the tube through which the blood flows (Fahraeus-Linqvist effects). Blood viscosity is studied clinically at different temperatures, and, above all, at different rates of deformation by carefully recording the hematocrit. Plasma viscosity, fibrinogen, albumia and immunoglobulin levels, the viscosity of blood cell suspensions in normal saline must also be taken into consideration. Special investigations (rheoscopy, filtrability) provide information about red cell aggregation and deformability. Hyperviscosity syndromes are observed with: --raised hematocrit (polycythemia and pseudopolycythemia), --conditions with raised serum proteins or changes in their composition (especially hyperfibrinogenemia, raised immunoglobulins, low albumin levels); inflammatory syndromes, dysglobulinemias (Fahey's syndrome of plasma hyperviscosity), --low temperature (hypothermia), --increased red cell aggregability (shock, fat embolism), --reduced red cell deformability due to various congenital and acquired conditions (sickle cell anemia, renal failure, hyperlipoproteinemia, thrombosis, diabetes). Conversely, hypoviscosity may occur with a low hematocrit, hypoproteinemia, hypofibrinogenemia, and hyperthermia. Increased viscosity results in a slowing of blood flow, stagnation of its constituents and in ischemia. Therapeutic interventions may be considered on the different components of the hyperviscosity syndrome: hemodilation, plasmapheresis, dispersion of aggregants, agents acting on red cell deformability.

A 10-year-old Tennessee Walker gelding, with a history of progressive weight loss, intermittent colic and lethargy, had a slight fever, tachycardia, tachypnea, pallor, ascites and marked ventral edema. Blood analyses revealed anemia, leukocytosis, neutrophilia with a left shift, lymphopenia, monocytosis, hypoproteinemia and a slightly increased SDH level. Abdominocentesis produced red-orange fluid with many RBC and an increased fibrinogen content. Rectal palpation revealed a large mass in the left caudal abdominal quadrant. The animal died shortly after resection of the mass. The histopathologic diagnosis was lymphosarcoma, involving the spleen, liver and lung.

In domestic pigs, intermitted application of Escherichia coli-endotoxin was used to create an animal model for a prolonged hypo- and hyperdynamic septic shock-like state and to investigate mechanisms of multiple organ failure. Here, we describe the changes in skeletal muscle after 18 h (2 animals) and 48 h (6 animals) of septic shock. Two pigs for each observation period that received physiologic saline solutions instead of endotoxin served as controls. The earliest lesions were endothelial cell damage with endomysial oedema and swelling of mitochondria in muscle fibres. With increasing degree of endothelial cell damage, pericytes showed degenerative changes with cytoplasmic fragmentation and karyolysis. After 48 h of shock, endomysial oedema was increased with fibrinogen present. Muscle fibre diameters were increased and swollen mitochondria and segmental necrosis of muscle fibres were frequently observed. However, phagocytic reaction or regenerative changes were not detected. In this respect, skeletal muscle lesions in septic shock differ from ischemic damage, which is characterized by early phagocytosis. Tumour necrosis factor alpha (TNF alpha) was increased greatly and significantly in the serum of the pigs that received endotoxin. The lesions described may be the result of both direct damage to muscle fibres by the endotoxin and/or the increased levels of TNF alpha and indirect damage because of the increased diffusion distance, due to the endomysial oedema. The loss of blood proteins into the endomysium may also play a role in generating hypoproteinemia in patients with septic shock.

A prospective longitudinal study was conducted to determine whether single-donor fresh frozen plasma (FFP) substitution was able to influence L-asparaginase-associated hypoproteinemia. Within a 36-month period, 20 of 42 children with ALL received a total of 42 prophylactic FFP doses at a median of 10 (5-20) mliter/kg when fibrinogen levels decreased to < 60 mg/dL and thrombin time was lengthened. Laboratory monitoring before, during and after FFP substitution showed no short-term improvements and demonstrated only a minimal increase in fibrinogen and alpha 2-antiplasmin. Plasma levels of antithrombin and plasminogen remained unchanged. Furthermore, administration of FFP had no influence on thrombin generation, the plasmin/alpha 2-antiplasmin complex or enhanced D-dimer formation.

The acute phase response to tissue injury is art of the wound healing process after surgery. The aim of study was to determine levels of acute phase proteins and levels of thrombocytes in patients with laparoscopic surgery (intraabdominal preperitoneal repair) and in patients with open surgery (tension free repair). Exclusion criteria in both groups of patients: malignity, diabetes mellitus, obesity (BMI > 30), infection, hypoproteinemia, hepatic or renal insufficiency and hypertension. Type of anaesthesia: general. Perioperative preventive antithrombotic medication: LMWH 5 days after surgery. The observed parameters were estimated before, one hour, 2nd and 7th days after surgery. Statistical test: ANOVA, statistical by significant difference p < 0.05. The results of the study demonstrate an increase of acute phase proteins CRP, OROSO and Fb in both groups of patients in comparison to their levels before surgery. In this respect we did not find a difference between the two types of operation. In patients with laparoscopic surgery the observed peak of FBG increase (+69%) was on the 2nd day after surgery followed by a slight drop of values in comparison to the results of open surgery patients with a FBG increase on the 2nd day (+42%) and with continuation on the 7th (%) postoperative day. The peak of CRP values was on the 2nd day in both groups. OROSO values increased even on the 7th day. The same situation occurred with Plt levels (p < 0.05). We suggested, that laparoscopic and open surgery of inguinal hernia repair are both followed by an acute phase response related to the tissue injury and this response perists even 1 week after surgery. But the recovery time of some parameters of the acute phase response (e.g. orosomucoid and fibrinogen levels) to the basical preoperative state is longer in patients with open type of surgery. We do not confirm differences in the degree of risk of postoperative thrombophilia in both types of surgery and suggest, that the prevention of thromboembolic complications is indicated in both types of surgery.

Dogs with sustained anemia plus hypoproteinemia due to bleeding and a continuing low protein or protein-free diet containing abundant iron have been used in the present work to test food proteins and supplements as to their See PDF for Structure capacity to produce new hemoglobin and plasma proteins. The reserve stores of blood protein-producing materials are thus largely depleted in such animals and sustained levels of 6 to 8 gm. per cent hemoglobin and 4 to 5 gm. per cent plasma protein can be maintained for considerable periods of time. The stimulus of double depletion drives the body to use all protein building materials with the utmost conservation. This represents a severe biological test for food and body proteins and its assay value must have significance. Measured by this biological test in these experiments, casein stands well up among the best food proteins. The ratio of plasma protein to hemoglobin is about 40 to 50 per cent, which emphasizes the fact that these dogs produce on most diets about 2 gm. hemoglobin to 1 gm. plasma protein. The reason for this preference for hemoglobin production is obscure. The mass of circulating hemoglobin is greater even in this degree of anemia and the life cycle of hemoglobin is much longer than that of the plasma protein. Egg protein, egg albumin, and lactalbumin all favor the production of more plasma protein and less hemoglobin as compared with casein. The plasma protein to hemoglobin ratio is increased, sometimes above 100 per cent. Supplements to the above proteins of casein digests or several amino acids may return the response toward that which is standard for casein. Histidine as a supplement to egg protein increases the total blood protein output and brings the ratio of plasma protein to hemoglobin toward that of casein. Beef muscle goes to the other extreme and favors new hemoglobin production up to 4 gm. hemoglobin to 1 gm. plasma protein-a ratio of 25 per cent. The total amounts of new blood proteins are high. Lactalbumin as compared with casein shows a lower total blood protein output and a plasma protein to hemoglobin ratio of 70 to 90 per cent. Amino acid supplements are less effective. See PDF for Structure Fibrin is a good food protein in these experiments-much like casein. When fed over these 5 week periods it causes a sustained increase in blood fibrinogen. Folic acid in the doses given has no effect on the expected response to various diets. Peanut flour is a very poor diet for the production of new hemoglobin and plasma proteins. Small supplements of casein and beef show a significant response with improved output of blood proteins. Soy bean flour gives a poor response and wheat gluten a good response with adequate output of blood proteins. Visceral products show some variety. Beef heart is not as effective as beef muscle. Beef spleen, kidney, and pancreas give good responses but not up to casein. Pig stomach, beef brain, and calf thymus are below average. The plasma protein to hemoglobin ratio shows a narrow range (40 to 60 per cent) in experiments with visceral products.

Neonatal intrahepatic cholestasis caused by citrin deficiency (NICCD) is a kind of inborn errors of metabolism, with the main clinic manifestations of jaundice, hepatomegaly, and abnormal liver function indices. As a mitochondrial solute carrier protein, citrin plays important roles in aerobic glycolysis, gluconeogenesis, urea cycle, and protein and nucleotide syntheses. Therefore citrin deficiency causes various and complicated metabolic disturbances, such as hypoglycemia, hyperlactic acidemia, hyperammonemia, hypoproteinemia, hyperlipidemia, and galactosemia. This paper reported a case of NICCD confirmed by mutation analysis of SLC25A13, the gene encoding citrin. The baby (male, 6 months old) was referred to the First Affiliated Hospital with the complaint of jaundice of the skin and sclera, which it had suffered from for nearly 6 months. Physical examination showed obvious jaundice and a palpable liver 5 cm below the right subcostal margin. Liver function tests revealed elevated enzymatic activities, like GGT, ALP, AST, and ALT, together with increased levels of TBA, bilirubin (especially conjugated bilirubin), and decreased levels of total protein/albumin and fibrinogen. Blood levels of ammonia, lactate, cholesterol, and triglyceride were also increased, and in particular, the serum AFP level reached 319,225.70 microg/L, a extremely elevated value that has rarely been found in practice before. Tandem mass analysis of a dried blood sample revealed increased levels of free fatty acids and tyrosine, methionine, citrulline, and threonine as well. UP-GC-MS analysis of the urine sample showed elevated galactose and galactitol. The baby was thus diagnosed with suspected NICCD based on the findings. It was then treated with oral arginine and multiple vitamins (including fat-soluble vitamins A, D, E, and K), and was fed with lactose-free and medium-chain fatty acids enriched formula instead of breast feeding. After half a month of treatment, the jaundice disappeared, and the laboratory findings, including liver function indices, blood levels of ammonia, lactate and AFP, were returned to normal level. The baby was followed up for 6 months. It developed well, and the abnormal laboratory findings, including MS-MS and UP-GC-MS analysis results, have been corrected, except a slightly elevated lactate level sometimes. SLC25A13 gene mutation analysis for the patient revealed a compound heterozygote of mutation 851del4 and 1638ins23 and therefore NICCD was definitely diagnosed.

The Eck fistula shunts the portal blood around the liver which receives its blood only by way of the hepatic artery. There are slight gross and histological changes in the Eck fistula liver of the dog. There is evidence at times of some functional abnormalities of the liver due to the Eck fistula but the dog can tolerate this fistula for 1 to 8 years and appear normal. Chloroform is tolerated by the Eck fistula dog, which may take twice a lethal dose for the control dog without evidence of significant liver injury. Acacia given by vein is deposited in the Eck fistula liver and impairs further its functional capacity to contribute to hemoglobin production. The stress of anemia brings out the fact that the anemic Eck fistula animal cannot utilize standard diet factors and iron as efficiently as the anemic non-Eck control dog. The output of new hemoglobin in some instances may drop to one-fourth of normal. When hypoproteinemia alone or combined with anemia is produced in the Eck fistula dog, we observe at times very low production of plasma protein-seven a drop to one-tenth of normal. This interrelation of liver abnormality, liver dysfunction, and lessened plasma protein and hemoglobin production is significant. It is generally accepted that the liver is concerned with the production of several plasma proteins-fibrinogen, prothrombin, and albumin. The experiments above indicate that the liver is concerned directly or indirectly with the production of new hemoglobin. Our belief is that the liver contributes to the fabrication of hemoglobin by means of the mobile plasma proteins which to a large extent derive from the liver.

The aims of this study were to evaluate the characteristics of hypercoagulable states in patients with membranous nephropathy (MN) via thromboelastography (TEG) and to identify risk factors. 235 MN patients who had undergone TEG examinations from 2011 to 2014 were included. An abnormality in at least two TEG parameters is considered a hypercoagulable state. Patient data was compared between the hypercoagulable and non-hypercoagulable groups. Potential risk factors for hypercoagulability were analyzed by logistic regression models. Subgroup analysis was performed in hypercoagulable patients. Compared to the non-hypercoagulable MN patients, the hypercoagulable patients showed a significantly higher proportion of female patients, urinary protein, platelet count, triglyceride and fibrinogen level, along with more severe hypoproteinemia and a reduction of serum antithrombin III. Correlation analysis showed that hypoproteinemia was the primary risk factor for hypercoagulability in MN patients. Among the hypercoagulable MN patients, a subgroup TEG parameter analysis showed that glucocorticoids-used subgroup and smoker subgroup had shortened time to initial fibrin formation (R value) and increased coagulation index respectively (P < 0.05), indicating a more serious hypercoagulable state. Meanwhile, the time to initial fibrin formation (R value) and time to clot formation (K value) of the statin-used patients were remarkably higher than those of the non-statin patients. TEG examinations facilitated the detection of hypercoagulable states in MN patients, and hypoproteinemia was the most important risk factor for hypercoagulability in these patients. The use of glucocorticoids and smoking may help to aggravate hypercoagulable states, while statin drugs may alleviate hypercoagulability.
