The macroscopic and microscopic findings of a case of Zieve's syndrome are described (fatty liver, icterus, hyperlipemia and hemolytic anemia in chronic alcoholism). The outstanding macroscopic finding is milky turbidity of the blood in arterial and venous vascular channels as well as hepatomegaly and anaemia of internal organs. A prominent feature of the histological picture is the high-grade lipaemia of the large and small vessels (arteries and veins), capillary occlusions resembling fat embolism in all organs and severe diffuse fatty metamorphosis of the liver. Circulatory disorders and the cause of death are discussed.

CD-1 mice were given oral doses of 0-16 ml/kg/day for five days of Prudhoe Bay (PBCO), South Louisiana and Arabian Light crude oils, Bunker C oil (BCO), mineral oil (MO) and corn oil. Minor decreases in packed cell volume and increases in mean corpuscular hemoglobin concentration occurred after ingestion of crude oils and BCO. Dietary depletion of vitamin E and selenium failed to enhance hematological changes. Pronounced liver enlargement and atrophy of thymus and spleen accompanied ingestion of all petroleum oils except MO and were shown to be dependent on dose of PBCO. Concentration of RNA and total RNA were increased while total DNA, but not concentration of DNA, was increased in enlarged livers. Liver enlargement was attributed primarily to hyperplasia with an additional contribution due to hypertrophy. The severe hemolytic anemia reported in marine birds that ingested PBCO was not reproduced in mice. Liver enlargement and lymphoid tissue atrophy were similar to those reported in other species exposed to petroleum oils.

Spontaneous leukemia occurred in 36% of a group of 39 aged Slc: Wistar rats, which ranged in age at death from 99 to 123 (average age: 114) weeks old. The leukemic rats showed hemolytic anemia, jaundice and leukocytosis (21,000 to 360,000/mm3). Macroscopically, they were characterized by splenomegaly and hepatomegaly. The leukemia cells were rich in basophilic cytoplasm containing eosinophilic granules. Their nuclei were oval and occasionally revealed mitotic figures. These leukemia cells were consistently transplantable into both Slc: Wistar and F 344/NSlc rats. In the transplanted cases, the latency and survival periods were prolonged in proportion to decreases in the inoculated cell dose.

An 8-month-old boy and a 7-month-old girl presented with an acute, Coombs-positive auto-immune haemolytic anaemia and severe hepatitis. The clinical manifestations were pallor, jaundice and hepatomegaly. The liver histology revealed diffuse giant cell transformation and extensive necrosis with central-portal bridging. Combined immunosuppressive regimen with steroids and azathioprine led to prolonged clinical and biological remission with a respective 2 years and 7 months follow up. The girl, however, after 7 months developed a progressive encephalopathy of unknown aetiology, while liver and haematological disease were still under control. She died subsequently from severe recurrent seizures. We conclude that acute Coombs-positive giant cell hepatitis of infancy can be improved by sustained immunosuppressive therapy.

Chronic lymphocytic leukaemia was diagnosed in 1957 in a 29-year-old male patient who lived 31 years after that time. At the time of diagnosis he was in good general condition with the enlarged liver (4 cm) and spleen (5 cm). In peripheral blood the leukocyte count was 47 x 10(9)/1 with 80% lymphocytes (38 x 10(9)/1), Hb 106 g/1; the bone marrow showed hypercellularity with predominance of lymphocytes. Treatment with corticosteroids was during 1958-1966. In 1967 Chlorambucil was given for 3 months, in 1972 for one month, inducing normalization of leukocyte count, 5.7 x 10(9)/1 with 40-50% of lymphocytes (3 x 10(9)/1). In 1977 the bone marrow showed slight lymphocytosis (38%). Numerous infections were recorded. Splenomegaly disappeared in 1980. In 1982 macrocytic anaemia was observed. Diagnosis of pernicious anaemia was established based on megaloblastic bone marrow and positive Schilling test. Vitamin B12 treatment resulted in reticulocyte response (crisis) and normalization of haemoglobin level. In 1988 light anaemia and melena appeared. Gastroscopy revealed lesions in the fornix histologically identified as ventricular carcinoma. It can be presumed that the appearance of pernicious anaemia as an autoimmune disease is analogous to other autoimmune complications in chronic lymphocytic leukaemia (haemolytic anaemia, thrombocytopenia).

Cyclohexanone oxime (CHO) was given po to male and female Fischer 344 rats at dose levels of 10, 25, 75, 150, and 300 mg/kg, five times a week for a period of 2 weeks. Control animals received distilled water. All animals given intermediate dose levels (10, 25, 75, and 150 mg/kg) and one half of the animals which were dosed at the high dose (300 mg/kg) as well as one half of the controls were terminated 14 days after administration of the first dose. The remaining rats received no treatment for an additional 14 days and were sacrificed on Day 28 of the study (recovery phase). Dose-related decreases in erythrocyte number, hemoglobin, and hematocrit, with an accompanying increase in reticulocytes and circulating nucleated erythrocytes, were observed in both sexes at Day 14. Methemoglobin levels, determined only at the high dose, were elevated in both sexes at this time. Splenomegaly and hepatomegaly were observed in both sexes at 14 and 28 days. Histopathological examination of the spleen and bone marrow revealed dose-related erythroid hyperplasia at 14 days which subsided by Day 28. The above effects were more pronounced in males. Erythrocyte numbers were only slightly depressed and reticulocytes mildly elevated in males at Day 28. Hematological values were not statistically different from controls in females at this time. These results suggest that CHO induces oxidative damage to the erythrocyte, resulting in a hemolytic anemia accompanied by increased erythropoiesis. The toxic effects appear reversible upon cessation of exposure.

Twenty-seven patients were seen and followed at our Sickle Cell Center over a period of seven years. Their clinical, hematological, and biochemical features were determined and compared to those of patients with sickle cell anemia who were concurrently investigated. The data indicate that the mild anemia of hemoglobin (Hb) SC disease is slightly microcytic and hyperchromatic. Parameters of hemolysis and the complications of chronic hemolytic anemia (cholelithiasis, leg ulcers, hepatomegaly, and cardiomegaly) are milder in Hb SC disease than in sickle cell anemia. Asplenia and its sequelae (increased platelet count and reduced serum IgM levels) are less frequent in Hb SC disease. Cerebrovascular accidents and the decreased leukocyte alkaline phosphatase scores are similar in both diseases. Thromboembolic complications, retinopathy, and renal papillary necrosis are more frequent in Hb SC disease.

After intraperitoneal injections of 2.5% aqueous methylcellulose twice a week for 15 weeks gerbils showed a mild haemolytic anaemia, heterophilia, lymphopenia and monocytosis. Many monocytes and a few lymphocytes had a foamy vacuolated cytoplasm. There was a sequestration of methylcellulose in the phagocytic cells of the spleen, liver, bone marrow and in other scattered foci, and consistent storage in the glomerular endothelium. Myeloid metaplasia was noted in the spleen, and splenic weights were markedly increased (P Less than 0.05); hepatomegaly was also present. The survival at the end of 15 weeks was 60%. From this experiment, the gerbil is considered to be a potential model for a stimulated monocyte-macrophage system.

Two cases of red cell aldolase deficiency associated with congenital nonspherocytic hemolytic anemia are reported. The proband is a fourteen-month-old Japanese boy. Consanguineous marriage was not proven but probable in this family, as the parents were born in the same small island. The proband had moderate to mild anemia aggravated by upper respiratory infections, 1 cm hepatomegaly and 2.5 cm splenomegaly, but was unremarkable in other respects and has thus far not shown mental or growth retardation. He did not have dysmorphic features. The red cell aldolase activity was 6% of the normal mean. The enzyme was unstable with respect to heat, and Km for fructose 1,6-diphosphate (F-1,6-DP) was high. The parents and other heterozygotes showed intermediate activity between that of the proband and that of normal subjects. Red cell F-1,6-DP concentration in this case was remarkably increased. Red cell glucose consumption, and lactate formation, as well as hexose monophosphate shunt activity, were decreased as compared with a comparable reticulocyte-rich hereditary spherocytosis patient. Hexose monophosphate dehydrogenase by a high concentration of F-1,6-DP in his red cells. As a result of family study, another homozygous aldolase deficiency case associated with hemolytic anemia was found. He is 13 years old and a nephew of the proband's paternal grandmother. His hemolytic anemia also is moderate to mild and aggravated by upper respiratory infections. He does not seem to have mental or growth retardation, nor does he possess dysmorphic features.

A 34-year-old female patient was admitted to our hospital with a 1-year history of chronic congestive heart failure, massive proteinuria and tibial edema. On admission, she presented with hemolytic anemia, hepatomegaly, splenomegaly and renal impairment. Furthermore, the skin of her face, hand, forearm, lower extremities showed crust and bulla. Laboratory examination revealed a large amount of protoporphyrin in her blood and feces, but no increase in urine. Light microscopy of renal biopsy showed moderate chronic tubulointerstitinal disease and mild proliferation of mesangial cells. The prophyians are a group of compounds associated with involving the disturbance of various biosynthetic heme pathwas. Until now, the regulation of porphyrin and heme metabolism in the kidney have received relatively little attention as compared with those in liver and erythropoietic tissue. However, some recent reports have confirmed that proximal tubular cells may contribute to heme biosynthesis. It was strongly suggested that chronic tubulointerstitinal injury in this case might be directly induced by the disturbance of the biosynthetic heme pathway in the tubules.
