Twenty mongrel dogs, weighing between 7.5 and 13.0 kg were used to investigate the percentage limits permissible for hemodilution using a double-helical reservoir heart-lung machine which has a 1,100 ml of priming volume. In both 40 and 50 per cent groups of intentional hemodilution by 30 minute extracorporeal circulation, remarkable anemia was inevitable and recovery was extremely slow, especially in the 50 per cent dilution group. In both 40 and 50 per cent groups of intentional hemodilutions by 30 minute extracorporeal circulation, metabolic acidosis was observed. In 50 per cent group of intentional hemodilution, no improvement of metabolic acidosis was observed even after perfusion. When sodium bicarbonate was administered to 40 per cent hemodilution group, minimum alterations of acid-base balance and of serum electrolytes were observed during and after extracorporeal perfusion. When sodium bicarbonate was administered to 50 per cent hemodilution group, metabolic acidosis was more evident than in 40 per cent hemodilution group accompanied with an increase in serum sodium concentration and a decrease in serum chloride concentration. These data qualify the use of 40 per cent intentional hemodilution using Lactate Ringer's solution or low molecular weight dextran for 30 minute extracorporeal circulation when sodium bicarbonate is administered in adequate amounts.

A new retravirus (SMRV) isolated from a squirrel monkey, Saimiri sciureus, has an Mg2+-dependen reverse transcriptase and a buoyant density of 1.17 g/cm3 in sucrose and 1.21 g/cm3 in cesium chloride, similar to the mouse mammary tumor virus and the Mason-Pfizer monkey virus. The polypeptide patter of SMRV as determined by sodium dodecyl sulfate-polyacrylamide gel electrophoresis was distinct from the reported polypeptide patterns of known retraviruses. Four major polypeptides of molecular weights 40,000, 20,000, 14,000 and 8,000 were resolved in virus propagated in human, mink, and canine cells. In A204 human rhabdomyosarcoma cells, a protein of 73,000 daltons (gp73) represented the major viral glycoprotein as determined by [3H]glucosamine labeling. Additional proteins were also observed, but their presence depended on the cell type in which the virus was propagated. In both species-and interspecies-specific assays, no antigenic relatedness was observed between SMRV and Mason-Pfizer monkey virus, mouse mammary tumor virus, baboon endogenous virus (BaLV), woolly monkey virus (SSV-1), murine leukemia virus, endogenous feline type C virus (RD-114), bovine leukemia virus, and equine infectious anemia virus. These findings indicate that SMRV represents a new retravirus and the first isolate from a New World monkey.

Two patients had diffuse, reversible pulmonary injury possibly owing to gold sodium thiomalate treatment: a 32-year-old woman with chronic inflammatory arthritis compatible with seronegative rheumatoid arthritis and a 32-year-old man with shoulder arthralgia. The patients had received 420 mg and 325 mg of gold sodium thiomalate, respectively. Cough and dyspnea began in the seventh and fifth weeks of therapy, respectively. In both patients x-ray study showed bilateral pulmonary infiltrates, with no evidence of pleural disease. The woman had no other manifestations of hypersensitivity to gold. The man had exfoliative dermatitis fever and anemia. Lung biopsies from both patients revealed lymphocytes and plasma cells infiltrating the alveolar septa and interstitial fibrosis. The woman improved slowly during four months after discontinuation of therapy. Pulmonary symptoms recurred after additional gold therapy, and again resolved when gold was discontinued. The man, treated with prednisone, showed prompt remission and remains will without medication.

Red blood cell plasma membranes contain a number of enzymes: ATPases, anion transport protein, glyceraldehyde 3-phosphate dehydrogenase, protein kinases, adenylate cyclase, acetylcholinesterase. Most of them are tightly bound to the membrane and are present in small amounts. As a result, structural characterization of erythrocyte membrane enzymes has not yet been successful. Functional studies have, however, yielded a great deal of information. ATPases allow active transport of cations (calcium, sodium, potassium). Anion transport protein controls movements of chloride and phosphate ions, and of glucose and water. Among glycolytic enzymes: glyceraldehyde 3-phosphate dehydrogenase is partially bound to the membrane. Protein kinases catalyze the phosphorylation of several membrane proteins, one of which (spectrin) is involved in red blood cell mechanical properties. The physiological role of adenylate cyclase is unknown. Acetylcholinesterase is an ectoenzyme. Calcium-dependent ATPase, adenylate cyclase and phosphorylation of erythrocyte membrane proteins have been found abnormal in various conditions: hereditary spherocytosis, sickle-cell anemia, progressive muscular dystrophies, all of these disorders being associated with a decreased deformability of the erythrocyte.

A case of 21 year old male with neuropathy caused by renal insufficiency was present. He had taken bromate (mixed powder of potassium bromate and sodium bromate) for the purpose of suicide and suffered from acute renal insufficiency and hard of hearing. Renal dysfunction improved gradually by peritoneal dialysis and hemodialysis. However, on the 32th day after the onset, burning pain appeared in the bilateral feets. Following this, he began to complain of the disturbances of superficial and deep sensory below the ankle jerks and the weakness of his toes. Considering the clinical features, we supposed that the disturbance of the peripheral nerve was caused by uremia due to taking bromate. N. suralis was biopsied on the 80th day after the onset and examined electron microscopically. Electroscopical findings was as follows. Degeneration of the Schwann cells and irregularity or destruction of the myelin sheaths were observed. The axoplasm of the myelinated nerve fiber were relatively preserved as compared with the changes of the myelin sheaths. In the unmyelinated nerve fibers, cavity formations were observed. The findings of regeneration were not observed. From the electron microscopical findings, we speculate that the changes of the Schwann cells and the myelin sheaths are primary resulting from the disturbance of the metabolism of the Schwann cells. We speculate that anemia and hypoproteinemia caused by bromate disturbed regeneration.

Twelve chemicals and commercial disinfectants were tested for inactivation of equine infectious anemia virus. In the presence of 10% bovine serum, all chemicals inactivated 4 log10 (based on 0.1 ml) of the virus within 5 minutes at 23 C. A reduction of at least 4 log10 was observed when the virus was exposed for 1 minute to substituted phenolic disinfectants (3 commercial preparations and sodium orthophenylphenate), halogen derivatives (iodophor and sodium hypochlorite), chlorhexidine, and 70% ethanol. Sodium hydroxide (5%), 2% formalin, and 2% glutaraldehyde were slower to inactivate the virus, but achieved 4 log10 reduction in titer by 5 minutes' contact time. The susceptibility of the equine infectious anemia virus to chemical disinfectants is similar to that of other enveloped viruses.

A simple method for preparation of highly specific antisera against equine infectious anemia virus proteins p26 and p16 is described. Viral proteins were separated by sodium dodecyl sulfate-polyacrylamide gel electrophoresis. The motility of the viral proteins in the gel was compared with standards. Unstained portions of the slab gel were sliced into 5-mm bands, emulsified with Freund's complete adjuvant, and injected into rabbits to produce specific antisera.

The clinical and laboratory features, and the response to treatment of visceral leishmaniasis were studied in 18 hospitalized patients. Clinical and laboratory findings were similar to those in patients with kala-azar in the Sudan and East Africa. Fever, heptosplenomegaly, relative lymphocytosis, leukopenia, low platelet counts, and severe anemia were common findings. Pentostam (sodium stibogluconate) was used to treat 17 patients and Neostibosam (ethylstibamine) for one. Three patients died. Four out of the 18 patients had not visited any known endemic area but the significance of this finding has not been fully evaluated.

Cytochemically, nonspecific esterase activity was detected in megaloblasts from three patients with severe untreated pernicious anemia, in megaloblastoid erythroblasts from five patients with chronic erythremic myelosis (DiGuglielmo syndrome), and in normoblasts from a patient with severe untreated iron-deficiency anemia. Nonspecific esterase activity in all of these erythroblasts was inhibited by sodium fluoride. Enzymatic activity could not be detected in normoblasts from normal marrows. Electrophoretically, three bands of nonspecific esterase activity could be visualized in marrow sonicates from the anemic patients and normal persons. All of these bands were inhibited by sodium fluoride. The results demonstrate that electrophoretically and in terms of fluoride inhibition, nonspecific esterases obtained primarily from erythroid precursors in various types of anemias are similar to nonspecific esterases found in normal marrows presumably containing a more heterogeneous population of cells.

The effects of dipyridamole on potassium and sodium content of human red blood cells from normals or from patients with hypochromic anaemia, and of normal red cells pretreated with menadione, have been studied. Dipyridamole added to the incubation medium decreases the loss of potassium and the accumulation of sodium in all three types of red cells incubated at 37 degrees C for 24 h, either with or without calcium. The possible mechanism underlying these effects of dipyridamole is discussed.
