In two dialysis centres in the same city, with a total of 56 patients on regular dialysis treatment, it has been shown that the tap water used for the production of the dialysate contains chloramines. Total chlorine concentration and percentage of chloramines varies from 0.5 to 1.1 ppm and from 40 to 95 per cent. There in a high percentage of Heinz bodies in the patients' erythrocytes, and incubation of red cells in vitro with the dialysate raises the methaemoglobin concentration and alters the hexose-monophosphate shunt. The patients' mean haematocrit improved from 23.13 +/- 4.41 SD to 25.93 +/- 5.17 SD (p less than 0.0025) with the administration of ascorbic acid, 500 mg given intravenously once a week, but an unexpected transitory increase of the total chlorine to 3.5 ppm resulted in a serious decline of the mean haematocrit to 20.80 +/- 5.22 SD (p less than 0.0001). Ascorbic acid added to the dialysate at a concentration of 1.7 mg/dl produced a great improvement in the anaemia and the almost total disappearance of Heinz bodies from the patients' red cells.

Careless handling of industrial wastes often creates problems for human health and the environment. Chronic arsenic toxicity, resulting from household use of arsenic-contaminated water occurred in 53 out of 79 members (67%) of 17 families residing in South Calcutta close to a factory that manufactured Paris-green (copper acetoarsenite). Clinical investigation of 20 of these affected persons showed typical skin pigmentation as well as palmar and plantar keratosis in all of them, while gastrointestinal symptoms, anaemia and signs of liver disease and peripheral neuropathy were seen in many. The water used by the affected families for drinking and cooking had been taken from shallow tubewells and had arsenic levels from 5.0 to 58 mg/l (WHO permissible limit, 0.05 mg/l). Other residents in the same area whose drinking-water came from deep tubewells or from tap water supplied by the Calcutta Municipal Corporation (arsenic levels, less than 0.05 mg/l) were not affected. The study confirms that arsenic in the shallow tubewells was due to the waste discharged by the factory producing Paris-green.

A 57-year-old male who had suffered from polycythemia vera (PV) and had been treated with pipobroman, carbazilquinon and busulfan for ten years presented with fever. CBC revealed anemia and thrombocytopenia without an increase of leukemic blasts (WBC, 7,700/microliters, RBC 294 x 10(4)/microliters, Hb 9.1 g/dl, Plt 1.5 x 10(4)/microliters). Bone marrow aspiration resulted in dry tap. Bone marrow biopsy showed hyperplastic marrow with fibrosis and no increase in leukemic blasts. Eleven days later the patient became leukemic and he died of DIC. Blast cells showed a high nucleo-cytoplasmic ratio, basophilic cytoplasm and cytoplasmic blebs. Cytochemical and immunophenotype analysis of the blast cells showed the following results; myeloperoxidase (-), chloroacetate esterase (-), Sudan black (-), acid phosphatase (+), acetate esterase (+), PAS (+), HLA-DR (+) and GPIIb/IIIa (+). Platelet peroxidase reaction on electron microscopy was positive in perinuclear spaces and endoplasmic reticulum. A diagnosis of megakaryoblastic transformation of PV was made. Although acute myelogenous leukemia has been shown to develop occasionally in the course of PV, acute megakaryoblastic leukemia with DIC following PV is a very rare condition.

A few cases of multiple myeloma associated with myelofibrosis has been reported. In Japan, such cases have been less reported. We report a case of IgD-myeloma with remarkable marrow fibrosis. A 44-year-old female was admitted to our hospital because of back pain. On admission her peripheral blood revealed anemia and leukopenia. Serum immunoelectrophoresis revealed M-protein of IgD and serum IgD level remarkably increased to 5420 mg/dl. Bone marrow aspiration resulted in dry tap every three times and its biopsy at iliac bone showed remarkable infiltration of myeloma cell and remarkable increase of reticulin fiber with marked decrease of normal hematopoietic cells. Her liver and spleen were not palpable and tear drop cells of erythrocytes were not shown in peripheral blood. We could not find view of myelofibrosis with chronic myeloproliferative disorders. Multiple myeloma associated with myelofibrosis is a interesting syndrome as clinical signs and course. So further investigation must be needed.

There are differences between young and adult organisms regarding toxokinetic aspects and clinical manifestations of heavy metal intoxications. Chronically, toxic Cd intake causes a microcytotic hypochromic anemia in young rats at lower exposure levels and after shorter exposure periods than in adult animals. Cd absorption is increased by co-administration of milk and in conjunction with iron deficiency. After long exposure periods toxic Cd concentrations accumulate in the kidney cortex; this process starts very early in life. In 3-year-old children Cd concentrations in the kidney can reach up to one-third of those found in adults. Hg++ and methyl-Hg can cause Hg encephalopathia, and frequently cause mental retardation in adults. Correspondingly, Hg++ accumulation in the brains of suckling rats is approx. 10 times higher than in grown animals. Milk increases the bioavailability of Hg++. In suckling rats Hg is bound to a greater extent to ligands in the erythrocytes. Methyl-Hg concentrations in breast milk reach 5% of those in maternal plasma and that is a severe hazard for breastfed children of exposed mothers. Toxic Pb concentrations can lead to Pb encephalopathia. A high percentage of surviving children have seizures and show signs of mental retardation. Anemia and reduced intelligence scores were recently observed in children after exposure to very low levels of Pb. Pb absorption is increased in children and after co-administration of milk. There are no definite proofs for carcinogenesis or mutagenesis after oral exposure to Cd, Hg, and Pb in man. Heavy metal concentrations were found in the same order of magnitude in commercial infant formulas and in breast milk. When infant formulas are reconstituted with contaminated tap water, however, Pb and Cd concentrations can be much higher. The average heavy metal uptake from such diets exceeds the provisional tolerable weekly intake levels set by the WHO for adults, calculated on the basis of an average food intake and a downscaled body weight. These considerations do not even provide for differences in absorption and distribution or for the increased sensitivity of children to heavy metal exposure. However, dilution effects for essential heavy metals were observed in fast-growing young children; this effect might be extrapolated to toxic metals. These theoretical considerations are compared with epidemiological evidence. A health statistic from Baltimore shows a decline of Pb intoxications in infants. This observation correlates with a simultaneous decline in exposure to Pb which was due, for example, to decreased use of lead dyes in house paints and the abolition of tin cans for infant food.(ABSTRACT TRUNCATED AT 400 WORDS)

A 70-year-old man, who had been diagnosed as primary myelofibrosis in 1987 at Tokyo Women's Medical School, was admitted to our hospital because of left hip-joint pain in May 1988. Physical examinations revealed marked hepatosplenomegaly and multiple reddish papules on the skin. The peripheral blood showed marked leukoerythroblastosis and severe anemia with poikilocytosis. Bone marrow aspirations were dry tap. Needle biopsy of iliac crest showed a diffuse fibrosis. Biopsy of the papules showed an extramedullary haematopoiesis. He was treated with low dose Ara-C for seven days. Although hepatosplenomegaly and skin papules were reduced, he died of pneumonia a month later. At autopsy, leukemic cells massively infiltrated into the multiple organs, including bone marrow. The cells were identified with megakaryoblast, as those were positive for factor VIII related antigen. As far as we know, this is the third case of primary myelofibrosis transformed into acute megakaryoblastic leukemia.

A 63-year-old man was admitted to our hospital with tremor and somnolence, followed soon by coma. Anemia and retinal bleeding were observed. The blood smear exhibited rouleaux formation and leukoerythroblastosis. A bone marrow aspiration resulted in dry tap. The biopsy specimens revealed remarkable infiltration of myeloma cells with fibrosis. The M-component of IgG-lambda type and hyper-ammonemia were detected in the serum. Liver and renal functions, however, were within normal range. His consciousness recovered after plasmapheresis. Two courses of VMCP (vincristine, melphalan, carboquone and prednisolone) did not affect the paraproteinemia. Five courses of VAD (vincristine, adriamycin and dexamethasone) could lower the level of IgG. He died of pneumonia. The plasma of some patients with multiple myeloma may contain unidentified factors which increase the plasma ammonia.

A young man of 27 years was admitted to the medical ward because of increasing ascites over 3 months. There were no signs of portal hypertension and a diagnostic tap produced hemorrhagic liquid. Ultrasound confirmed ascites associated with an abdomino-pelvic mass. Anemia progressed and right aorto-iliac axis arteriography was carried out and demonstrated a poorly vascularised mass. Emergency surgery was carried out and demonstrated an encapsulated firm and cystic abdomino-pelvic mass of 23/18 cm with a rich vascular supply from the greater omentum and a hemoperitoneum of 7 litres secondary to rupture of this pseudo-lymphangiomatous mass. Besides large vessels from the and some loose fibrous adhesions in the pouch of Douglas there was no true implantation site attaching this mass to retroperitoneal structures, gastrointestinal tract or bladder. After ligation of the vessels the entire mass was easily resected. The post-operative course was uncomplicated. Pathological examination confirmed a paraganglioma. A full clinical pathogenic, therapeutic and evolutive study is described.

A case of primary myelofibrosis complicated with pericardial effusion and proteinuria is described. A 66-year-old female was admitted to our hospital because of abdominal fullness and shortness of breath. On admission, hepatosplenomegaly and pericardial effusion were observed. Blood examination revealed leukoerythroblastic anemia and thrombocytosis with tear drop cells and giant platelets. Bone marrow aspiration was dry tap and its biopsy showed remarkable myelofibrosis. Urinalysis indicated severe proteinuria. Although neutrophilic alkaline phosphatase score was low, no signs of acute blastic crisis of chronic myelogenous leukemia was found. The diagnosis of an atypical type of primary myelofibrosis was obtained. Administration of MCNU was started in August 1987. Hepatosplenomegaly, pericardial effusion and proteinuria were gradually improved after the administration. The etiology of the pericardial effusion and proteinuria were not obvious, however, these facts suggest that these abnormal findings might be related to PMF itself and MCNU was effective to PNF.

Mice ingesting 30 to 50% D2O (heavy water, deuterium oxide) developed a dose-dependent depression of formed peripheral blood elements in 4 to 9 days. The principal mechanism of anemia and thrombocytopenia is impaired hematopoiesis. Despite pancytopenia in the peripheral blood, bone marrow cellularity and morphology remained normal. Upon replacement of D2O with tap water, platelet and neutrophil concentrations returned to normal within 48 to 72 hr. In contrast, blood lymphocyte concentrations remained low for several weeks. B-lymphocytes may be more affected by deuteration than other lymphocyte subsets. In vivo reticuloendothelial cell function, as assessed by 51Cr-labeled sheep erythrocyte clearance, was unaffected by D2O. Although a dose-dependent decrease in fluid intake occurred during deuteration, hematocytopenia was not a consequence of dehydration. In view of the known kinetics of D2O in biological systems, the rapid response of myeloid elements to deuteration must be due primarily to the solvent (nonmetabolic) isotope effect. Prolonged deuteration has proven toxic when included in regimens for treatment of neoplasia, including leukemia, in animal models. The present study shows that modulation of hematopoiesis by D2O is possible without invoking the toxicities associated with prolonged deuteration.
