In normal mongrel dogs, outflow occlusion of 15 or 30 minutes duration was produced by clamping both the suprahepatic and suprarenal portions of the vena cava. One dog died immediately after release of occlusion; two dogs died from recurrent hypotension between six and 24 hours postoperatively. The other five dogs survived for three days, at which time an autopsy was done. During outflow occlusion, the blood pressure fell in all dogs, as did the central venous pressure. The pulse rate decreased during, and after, occlusion but toward a tendency of gradual recovery. A significant drop in pH and base excess of arterial blood was seen after occlusion. Although a steady, but not substantial, increase in hemoglobin and hematocrit values was noted, there were no remarkable changes in the blood coagulation system. Significant increases in serum glutamic-oxalacetic transaminase, glutamic-pyruvic-transaminase, lactic dehydrogenase, acid phosphatase and beta-glucuronidase activities were observed from immediately after release of occlusion, but alkaline phosphatase values increased much later than did these. Thus, hepatic outflow occlusion, even if it is short, seems to be dangerous in the dog, since it produces hypotension, metabolic acidosis and diffuse damage as well as disruption of the parenchyma of the liver.

A newborn infant presented with hepatosplenomegaly, rash, anemia, and leukocytosis at one day of age and manifested characteristic myeloid metaplasia by one mouth of life. Vitamin B12 and leukocyte alkaline phosphatase were elevated and platelet aggregation was impaired. Myelofibrosis was not present and neutrophil function was preserved. An unidentified high isoelectric point hemoglobin with unusual chromatographic and electrophoretic behaviors was found to comprise 12% of the total hemoglobin. The myeloid metaplasia and mutant hemoglobin disappeared over the subsequent months without biochemical or clinical residual. The available evidence was consistent with the mutant hemoglobin representing either a gamma chain or clonal embryonic chain variant. The inability to clarify prognostic factors in these unusual myeloproliferative syndromes suggests caution in the initiation of cytotoxic therapy.

Myeloproliferative disease of childhood is frequently associated with chromosomal anomalies, usually of the C group. Clinical features are similar to those of the juvenile type of chronic myeloid leukemia. A child with this disease is described. Marked myeloid proliferation, anemia, thrombocytopenia and hepatosplenomegaly were present; leukocyte alkaline phosphatase and fetal hemoglobin were moderately elevated. Chromosome analysis of bone marrow cells revealed a mosaicism 47,XX,+21/46,XX. Down's syndrome was ruled out by the child's normal phenotype and dermatoglyphic analysis. The cytogenetic finding is probably evidence for the clonal origin of the trisomy 21 cell line.

We evaluated gastrointestinal absorption in six consecutive patients with metastatic serotonin-secreting carcinoid tumors. One patient had a consistent defect in fat absorption and two other patients malabsorbed fat during spontaneous or dopamine-induced exacerbation of the carcinoid syndrome. The steatorrhea of the patient with the persistent defect in fat absorption was reduced when tumor serotonin production was reduced by the tryptophan hydroxylase inhibitor parachlorophenylalanine. The six patients had normal hemoglobin levels and the serum concentration of the following urinary constituents was normal in most of the patients: albumin, carotene, 25-hydroxycalciferol, parathyroid hormone, calcitonin, calcium, phosphorous, osteogenous alkaline phosphatase, cholesterol, triglycerides, and serum lipoproteins. The excretion of the following urinary constituents was also normal in most of the patients: creatinine clearance, tubular reabsorption of phosphorous, calcium, D-xylose, cyclic 3'5' monophosphate and hydroxyproline. We conclude that patients with the carcinoid syndrome may have steatorrhea, and that their hyperserotoninemia plays a role in this process.

Humans are exposed to a number of toxic elements in the environment; however, most experiments with laboratory animals investigate only one toxic element. To determine if concomitant exposure to lead (Pb), cadmium (Cd), and/or arsenic (As) modified the changes produced by any one metal in various parameters of toxicity, 168 male, Sprague-Dawley, young adult rats were fed nutritionally adequate diets to which had been added 0 or 200 ppm Pb as Pb acetate, or 50 ppm Cd as Cd chloride, or 50 ppm As as sodium arsenate or arsanilic acid in a factorial design for a period of 10 weeks. At these concentrations, Cd and As reduced weight gain even when differences in food intake were taken into account; administration of both Cd and As depressed weight gain more than did either metal alone. Pb did not adversely affect food consumption or weight gain. Increased numbers of red blood cells (RBCs) were observed following administration of Pb, Cd, or As; usually more cells were observed when two or three metals were administered, compared to individual metals. Despite increasing numbers of circulating RBCs, hemoglobin and hematocrit were reduced, especially with the Pb-Cd combination and the Cd-arsanilic acid combination. Specific effects of Pb on heme synthesis were observed, including increased urinary excretion of delta-aminolevulinic acid; this increase was reduced by the presence of dietary cadmium. Analyses of blood showed values for the laboratory rat within normal ranges for blood urea nitrogen, creatinine, cholesterol, calcium, albumin, total protein, and bilirubin. Uric acid was increased by Pb, with little modification by dietary Cd or As content. Serum glutamate-oxalate transaminase activity was reduced by As. Serum alkaline phosphatase was greatly reduced by either As or Cd but not Pb. Combinations of As and Cd did not further reduce the activity of this enzyme. Kidney weight and kidney weight/body weight ratios were increased by Pb alone, with no effects of Cd or As alone or as interactions. Liver weight/body weight ratios were reduced in animals fed 50 ppm dietary Cd. Kidney histology shows predominantly Pb effects, namely, intranuclear inclusion bodies and cloudy swelling. Ultrastructural evaluation of kidneys from Pb-treated animals disclosed nuclear inclusion bodies of the usual morphology and mitochondrial swelling. Concurrent administration of Cd greatly minimized Pb effects on the kidney under conditions of this experiment. Liver histology suggests an increased rate of cell turnover with either As compound, but few specific changes.

The efficacy of a new estrogen-progestin contraceptive agent Ovidon was evaluated in 65 women. The women were taking the contraceptive for 47 cycles (each Ovidon pill contained 0.25 mg of D-norgestrel and 0.05 mg of ethinyl estradiol). Prior to the Ovidon treatment, 15 women did not use any contraceptive agents or devices, 5 used hormonal contraceptives, 2 used IUDs, 4 used mechanical devices, 20 practiced coitus interraptus, and 9 used a biological method. Ovidon administration provided a 100% contraceptive effect. Side effects of Ovidon included fatigue (15 women), headache (4), irritability (3), fullness of the breast (27), hemorrhage (12), vaginal discharge (6), and changes in libido (22). Ovidon administration did not induce amenorrhea. A 1-3 kg weight gain was observed in 5 women. Laboratory studies showed no changes in hemoglobin levels, leukocyte count, cholesterol, and alkaline phosphatase levels. These findings indicated the safety and contraceptive efficacy of Ovidon.

Leukocyte alkaline phosphatase levels (LAPL's) were determined in 62 patients with multiple myeloma over a 13-year period. Sixty of the 62 myeloma patients had consistently elevated LAPL's, one patient had normal LAPL, and one patient had an initially normal LAPL which later increased. Elevated LAPL's could not be correlated with age, hemoglobin levels, white blood counts, or elevation of the blood urea nitrogen. LAPL's did not change during objective or subjective responses to chemotherapy or with progression of disease. We suggest that some feature of myeloma may "turn on" an abnormal clone of cells which may be responsible for the elevated LAPL's in patients with multiple myeloma.

In order to verify the influence of sampling time on blood constituents, populations of supposedly healthy subjects were grouped according to age, sex, deviation from their ideal weight, state of fasting or nonfasting, and time of sampling. Each fasting subject in one group underwent two samplings during the course of a morning: the first at 08.00 and the second between 09.00 and 12.00. In the second group, the first was taken at 13.00, and the second between 14.00 and 16.00. Subjects in the second group had eaten a standard meal of 700 calories at 12.00. Differences between the paired samples from a given individual are discussed with respect to the time of sampling for plasma urea, creatinine, proteins, albumin, calcium, sodium, potassium, cholesterol, uric acid, chloride ions, phosphate, bilirubin, aspartate aminotransferase, alanine aminotransferase, lactate dehydrogenase, creatine phosphokinase, alkaline phosphatase, hemoglobin and erythrocyte and leukocyte counts. Variations due to the time of sampling were large for phosphorus, bilirubin, and leukocyte count.

Hematological and biochemical parameters in five Thoroughbred foals during the first six months of life are reported. The samples were analyzed for red blood cell, packed cell volume, hemoglobin, platelet, white blood cell, absolute number for leukocytes, and erythrocyte fragility and serum calcium, inorganic phosphorus, sodium, potassium, chloride, magnesium, alkaline phosphatase, icterus index unit, bilirubin, blood urea nitrogen, nonprotein nitrogen, blood glucose, lacticdehydrogenase, glutamic pyruvic transaminase, glutamic oxalacetic transaminase, total protein, albumin, globulin, and A/G. The changes of these parameters are presented in relation to age after birth.

A 22-year-old black male presented with erythrocytosis and proteinuria. The erythrocytosis was characterized by increased red cell mass, normal arterial oxygen saturation, and normal hemoglobin electrophoresis and oxygen affinity. There was no splenomegaly, and the white blood cell count, platelet count, serum uric acid concentration, serum B12 levels and leukocyte alkaline phosphatase activity were normal. Tumors of the liver, lung, kidney and cerebellum, which have been associated with erythrocytosis, were not found. The only associated disease was biopsy proven focal glomerulosclerosis. Renal vein thrombosis was excluded by renal venography and arteriography. This case illustrates the rarely reported association of the nephrotic syndrome and erythrocytosis. Other nephrogenic causes of erythrocytosis are mentioned, including renal cysts, tumors, renal artery stenosis and transplantation. The role of the kidney in erythropoietin production and possible mechanisms of nephrogenic erythrocytosis are discussed.
