Abstract
Normal human RBCs have a very low basal permeability (leak) to cations, which is continuously corrected by the Na,K-ATPase. The leak is temperature-dependent, and this temperature dependence has been evaluated in the presence of inhibitors to exclude the activity of the Na,K-ATPase and NaK2Cl transporter. The severity of the RBC cation leak is altered in various conditions, most notably the hereditary stomatocytosis group of conditions. Pedigrees within this group have been classified into distinct phenotypes according to various factors, including the severity and temperature-dependence of the cation leak. As recent breakthroughs have provided more information regarding the molecular basis of hereditary stomatocytosis, it has become clear that these phenotypes elegantly segregate with distinct genetic backgrounds. The cryohydrocytosis phenotype, including South-east Asian Ovalocytosis, results from mutations in SLC4A1, and the very rare condition, stomatin-deficient cryohydrocytosis, is caused by mutations in SLC2A1. Mutations in RHAG cause the very leaky condition over-hydrated stomatocytosis, and mutations in ABCB6 result in familial pseudohyperkalemia. All of the above are large multi-spanning membrane proteins and the mutations may either modify the structure of these proteins, resulting in formation of a cation pore, or otherwise disrupt the membrane to allow unregulated cation movement across the membrane. More recently mutations have been found in two RBC cation channels, PIEZO1 and KCNN4, which result in dehydrated stomatocytosis. These mutations alter the activation and deactivation kinetics of these channels, leading to increased opening and allowing greater cation fluxes than in wild type.

Abstract
Hereditary xerocytosis (HX) is a rare haemolytic disease due to dehydrated red blood cells (RBCs). A unique feature of this syndrome is that affected members often show normal or near normal haemoglobin levels despite clinical and laboratory evidence of mild to moderate haemolysis. The diagnostic clue is the association of markedly increased RBC Na+ + K+ fluxes with low total cation (Na+ + K+) content. 11 patients of six unrelated families of Spanish origin with HX have been studied from clinical, genetical and biological points of view. In addition, we have investigated the sensitivity of RBC membrane to heat at three different incubation times (15, 30 and 60 min) and two different temperature values (46 degrees C and 49 degrees C). Under these conditions control RBCs (50 normal subjects) exhibited at 49 degrees C and 30 min a maximum of 30% fragmented RBCs. This value increased to 80% after 60 min of incubation. In contrast, patients with HX showed significantly lower percentages of fragmented RBCs at both 30 and 60 min of incubation (maximum 10% and 30%, respectively). In an attempt to determine if increased heat stability was unique to HX RBCs, several other congenital membranopathies with haemolytic anaemia were also studied. The degree of fragmentation, except in one case of HPP (which was strongly increased), did not differ from the control group. Electrophoretic studies of membrane proteins performed in RBCs of all the patients with HX did not explain any qualitative nor quantitative abnormality. In addition to its physiopathological interest, study of RBC heat stability, together with other haematological parameters (increased MCHC and decreased RBC osmotic fragility), may be useful for HX diagnosis, especially in laboratories which are not equipped to evaluate RBC membrane permeability.

Abstract
This study has examined the effect of MDA, an end product of lipid peroxidation, on the viscosity of AA and SS RBC suspensions. MDA accumulation in RBC was accomplished in vitro in human RBC by treating them with exogenous standard MDA. MDA accumulation assessed by the thiobarbituric acid reactivity of in vitro MDA-treated RBC was comparable to that of the RBC in vivo in hemolytic anemias. There was a significant increase in the viscosity of both AA and SS RBC suspensions after in vitro treatment with MDA. The increase in viscosity or RBC was significantly positively correlated with the extent of MDA accumulation.

This study has examined the effect of malonyldialdehyde (MDA), an end product of lipid peroxidation, on the K+ leak in normal (AA) and sickle (SS) red blood cells (RBCs). In vitro MDA accumulation in human RBCs was accomplished by treating them with exogenous standard MDA. MDA accumulation assessed by the thiobarbituric acid reactivity of in vitro MDA-treated RBCs was comparable to the RBCs in hemolytic anemias. There was a significant K+ leak in AA RBCs after in vitro treatment with MDA. The effect of MDA on the K+ leak was greater in SS RBCs. The increase in cellular K+ leak was significantly positively correlated with the extent of MDA accumulation as assessed by thiobarbituric acid reactivity.

Abstract
Normal and chronically dehydrated (hereditary xerocytosis) human red cells were subjected to mild peroxidative treatment (315 microM hydrogen peroxide (H2O2), 15 min) in the presence of azide. The subsequent expression of passive (ouabain-resistant) K+ transport activities was analyzed by measurement of 86Rb+ influx. Peroxidation of normal red cells did not affect basal K+ transport activity, but the increment in K+ influx elicited by 0.5 mM N-ethylmaleimide (NEM) was increased 3-fold. The enhanced K+ influx was chloride-dependent, but only partially inhibited by 0.1 mM furosemide. Stimulated activity declined progressively after NEM activation, but could be restored by a second NEM treatment. Prior conversion of hemoglobin to the carbonmonoxy form abolished the response to peroxide, while 200 microM butylated hydroxytoluene (BHT) exerted only partial inhibition, suggesting that the effect of H2O2 requires interaction of activated, unstable hemoglobin species with the membrane, but that lipid peroxidation is not sufficient. Peroxidation following NEM treatment also enhanced NEM activation, indicating that enhancement does not require altered NEM reactions with stimulatory or inhibitory sites. Passive K+ transport in hereditary xerocytosis red cells was not activated by NEM, with or without H2O2 pretreatment. The results demonstrate that modest peroxidative damage to red cells can heighten the activation of a transport system that is thought to be capable of mediating net K+ efflux and volume reduction in cells that express it. Models are proposed in which the effects of NEM, H2O2, cell swelling and other factors are mediated by conformational changes in a postulated subpopulation of anion channel (Band 3) molecules that bind the K+ transporter.

Abstract
The aim of this study was to establish the conditions for malonic dialdehyde liberation from smoked fish and curing smoke condensates, as well as to determine its content in smoked fish. The specific absorption peaks of coloured solutions of malonic dialdehyde, from curing smoke condensates, with 2-thiobarbituric acid were determined. The conditions for malonic dialdehyde liberation were established, i.e. time and degree of alkaline hydrolysis of condensate, degree of distillation of acidified condensate solution, the conditions of coloured solution development, determination of extinction and method of calculation of malonic dialdehyde content in smoked fish, in individual layers of smoked mackerel fillets. The mechanism of formation of polycyclic aromatic hydrocarbone and hydrogen peroxide or hydroxyl free radicals, formed during pyrolysis of organic compounds in the presence of liberated malonic dialdehyde, was proposed.

Abstract
Phospholipid distribution across erythrocyte membrane bilayer is asymmetrical. In normal erythrocytes, entire phosphatidylserine (PS) and most of the phosphatidylethanolamine (PE) is present on the cytoplasmic side of membrane bilayer, whereas phosphatidylcholine (PC) and sphingomyelin (SM) are predominantly present at the outer side of membrane bilayer. The present study was undertaken to determine whether membrane lipid peroxidation has any effect on the distribution of PS, PE, and PC across erythrocyte membrane bilayer in vivo in an animal model. Erythrocyte membrane lipid peroxidation was induced in rats by administering phenylhydrazine, an oxidant drug. Membrane phospholipid organization was determined by using bee venom phospholipase-A2 and indirectly by measuring clotting time on recalcification of normal human platelet-poor plasma in the presence of Russell's viper venom. Phenylhydrazine administration to rats caused significant membrane lipid peroxidation as measured by the accumulation of malonyldialdehyde (MDA), an end product of fatty acid peroxidation, as well as externalization of a significant portion of PS and PE from the inner to the outer side of membrane bilayer in erythrocytes. There was a significant positive correlation (r) between the amount of MDA accumulated in the erythrocytes and the movement of PS (r = 0.92) and PE (r = 0.96) from inner to the outer membrane bilayer and PC (r = 0.81) from outer to the inner membrane bilayer. Erythrocytes of phenylhydrazine-treated rats also showed significantly reduced clotting time. This reduction in clotting time had a significant positive correlation with MDA accumulation (r = 0.92) and PS externalization (r = 0.90). Both the effect of phenylhydrazine on erythrocyte membrane lipid peroxidation and alterations in phospholipid organization and coagulability were blocked when rats were simultaneously administered with vitamin E or C antioxidants.

Abstract
Protein crosslinkages are apparent at 215 000-250 000 daltons in electrophoregrams of membranes from hydrogen peroxide treated erythrocytes (British Journal of Haematology, 48, 435, 1981). Hydrogen peroxide is also capable of inducing crosslinkages of identical molecular weights in stage I and II (red) ghosts and in a mixture of purified spectrin and haemoglobin, but not in white ghosts or in either spectrin or haemoglobin alone. Autoradiographic studies using 14C-methaemoglobin and 32P-spectrin confirm the involvement of spectrin and haemoglobin in this reaction. The alpha chains of both proteins are more reactive than the corresponding beta chains: 3 times more reactive in the case of spectrin and 10 times more reactive in haemoglobin. The reaction is almost totally inhibited by NaCN and partially inhibited by N-ethylmaleimide. Direct addition of malondialdehyde to a spectrin-haemoglobin mixture does not result in protein crosslinkage. Metabolic depletion (40 h), in vivo ageing and sucrose dehydration of fresh, normal cells enhance the reaction considerably, whereas in vitro rehydration of xerocytes normalizes their H2O2 sensitivity.

Abstract
Erythrocyte membrane lipid peroxidation has been reported to occur in various haemolytic anaemias. In the present study, treatment of human erythrocytes with malonyldialdehyde (MDA), a product of fatty acid peroxidation, induced membrane rigidity, cellular dehydration and reduced whole cell deformability. These effects of MDA were blocked by histamine and fluorescamine, which can act as alternate substrates for MDA. Additionally, reduced deformability of MDA-treated rabbit cells was associated with shortened 51Cr survival in vivo. These findings suggest a biochemical basis for decreased survival of erythrocytes undergoing peroxidative damage of the membrane.

Abstract
A survey of the capacity of erythrocyte suspensions to handle a standard hydrogen peroxide oxidative load was made in a population of white male hospitalized alcoholics and non-hospitalized, non-alcoholic subjects. As measured by malondialdehyde (MDA) production, the capacity to handle this oxidation load was decreased in a significant percentage of individuals with a positive family history of alcoholism and who have experienced problems with alcohol sufficient to produce cytopathological changes and to require hospitalization.

Abstract
The red cells from 5 related patients with hereditary stomatocytosis were investigated. Maximal rate constant of Na+ passive permeability was increased while that of K+ passive permeability was nearly normal. Ouabain-sensitive Na+ efflux was elevated. The Na+ component of furosemide-sensitive Na+, K+ cotransport was also increased. However, its K+ component, determined in 2 patients, remained within normal limits, thus departing from the strict 1:1 stoichiometry of the Na+, K+ cotransport system. Yet, intracellular Na+ and K+ concentrations displayed limited and inconstant changes. A variety of abnormally-shaped cells, including stomatocytes, were observed in scanning electron micrographs. Upon differential centrifugation, reticulocytes usually concentrated in the most dense region of the gradient. Red cell deformability, as studied by ektacytometry, was reduced. Membrane phosphatidylcholines and sphingomyelins were increased and decreased, respectively, where-as fatty acid distribution was unchanged. Membrane microviscosity was normal.

Abstract
Hereditary xerocytes appear larger than normal red cells in scanning electron micrographs and exhibit a higher ghost packing volume. The major chemical components--protein, phosphorus, cholesterol and sialic acid--are increased uniformly, as are all polypeptides visible on gel electrophoresis patterns of xerocyte membranes. These data are consistent with a xerocyte surface area 15 to 25% above normal. Certain clinical anomalies common to this disorder, including unexpectedly low reticulocyte count and 2,3-diphosphoglycerate level, are discussed in the light of the present findings.

Abstract
Osmotically resistant red cells associated with some haemolytic anaemias, including hereditary xerocytosis, sickle-cell disease and beta thalassaemia minor, are more sensitive than normal red cells to exogenous in vitro hydrogen peroxide (H2O2). This sensitivity is manifested by a rapid loss of intracellular potassium, shape change, protein aggregation, and methaemoglobin formation at lower concentrations of H2O2 (225 microM) than are required to induce similar effects in normal red cells (450 microM). Malonyldialdehyde (MDA) formation occurs later than the other effects and can be inhibited by the antioxidant, butylated hydroxytoluene (BHT), without affecting protein aggregation or potassium leak. Incubation of normal red cells directly with MDA induces protein aggregation, but only after 1 h of incubation. Although nystatin-sucrose treated normal cells which are dehydrated with altered cation content, and therefore osmotically resistant, do not display abnormal H2O2 hypersensitivity as manifested by excessive potassium permeability, they do show an increase in methaemoglobin formation and protein aggregation similar to xerocytes. These data indicate that membrane protein cross-linking occurring immediately following H2O2 exposure seems independent of either the sulfhydryl or MDA mechanisms, and that the membrane permeability of the abnormal red cells predisposes them to oxidative damage.
