A 65-year-old man visited our department for further leukocytosis examination. Hematological examinations disclosed elevation of the leukocyte count with left deviation. The neutrophilic alkaline phosphatase score was reduced. Bone marrow was hypercellular and consisted almost entirely of granulocytic cells in all stages of maturation. However, cytogenetic analysis revealed no Philadelphia chromosome, and genotypic analysis disclosed no bcr rearrangement. He was ultimately diagnosed as having unclassified chronic myeloproliferative disorder. He had been followed without chemotherapy, and he developed blastic crises (CD10+, CD13+, CD24+). Chemotherapy was effective, and then he was followed with carboquone. However, myeloid crisis (CD13+, CD33+) developed again. Standard chemotherapies had no effect, he developed pneumonia, and he was in poor general condition. Therefore, low-dose combination with cytarabine and etoposide was performed. The result was that the blasts disappeared, his general condition improved and infection was reduced. Major side effects were absent; however, the blasts proliferated again after the treatment was discontinued. In conclusion, this combination may be useful treatment for myeloid blastic crises even if the patient is in poor condition. But the modification of the administration schedule requires some consideration.

A mature, female cockatiel (Nymphicus hollandicus) was examined because of respiratory difficulties. Clinical and laboratory findings included ascites and evidence of hepatic disease (i.e., increased plasma bile acid concentrations, aspartate aminotransferase, and alkaline phosphatase activities). Plasma protein electrophoresis results were consistent with chronic-active inflammation. The albumin-to-globulin (A:G) ratio, calculated from plasma electrophoresis, was 0.3. Postmortem examination revealed severe hepatic fibrosis and a diffuse, interstitial, granulomatous lipid pneumonia.

We report a novel strategy, called end-product (EP) amplification, capable of enhancing the sensitivity of immunohistochemical procedures by about an order of magnitude or more. The strategy employs an antibody (anti-EP) to the product generated by the action of horseradish peroxidase on 3,3'-diaminobenzidine (DAB), and can be extended to the products of other enzymes as well, e.g., alkaline phosphatase. Amplification is the consequence of the ability of anti-EP to detect the multiplicity of product moelcules resulting from the turnover of substrate by a single enzyme molecule. The subsequent detection of anti-EP was by biotinylated goat anti-rabbit antibody, followed by avidin-peroxidase and DAB or by avidin-alkaline phosphatase and Vector Red. Further amplification can be accomplished by repeated cycles of the protocol. Anti-EP was produced by immunization with a bovine serum albumin (BSA) conjugate of a soluble polymer of DAB, prepared by a carefully controlled reaction of DAB with horseradish peroxidase and hydrogen peroxide. Coupling to BSA (and to RSA) was accomplished with glutaraldehyde. The titer of anti-EP was established by ELISA. Formalin-fixed, paraffin-embedded sections of five cases of Hodgkin's disease and five tonsils with follicular hyperplasia were immunolabeled for the following lymphoid markers: CD3, CD20, CD30, CD45RA, and CD68. EP amplification with anti-EP was also applied to cases of CMV pneumonia and cerebral toxoplasmosis to determine whether this procedure could improve detection of the infectious agents. Immunolabeling of the primary antibody was performed by the avidin-biotin-peroxidase technique with DAB as the reaction substrate. The specificity of EP amplification was tested by demonstrating binding of anti-EP with Vector Red with the generation of a fluorescence end-point. There was complete congruence in the distribution of the DAB signal and the red immunofluorescence representing EP amplification. The intensity of the DAB signal was increased as much as 16-fold by EP amplification, making possible a reduction in the amount of the primary antibody by as much as 85-90%. Sensitivity also increased with respect to weakly expressed antigens and low concentrations of infectious agents.

A 30 year old man developed lipoid pneumonia after an injection of lamp oil. In addition to "foamy" alveolar macrophages, bronchoalveolar lavage (BAL) fluid analysis showed an increased number of neutrophils. Moreover, lactate dehydrogenase (LDH) and alkaline phosphatase activities were elevated. The increase seen in LDH activity both in serum and BAL fluid was accompanied by shifts in the isoenzyme pattern in similar directions for both fluids. These findings suggest a pulmonary source for the temporary serum as well as BAL fluid LDH increase. This case indicates the usefulness of bronchoalveolar lavage fluid analysis as a probe to detect pulmonary injury caused by a pneumotoxicant and, probably, to monitor recovery or deterioration.

Signalment, clinical signs, and physical examination and clinicopathologic findings in dogs diagnosed with Hepatozoon canis parasitemia (n = 100) were compared with those in Hepatozoon-negative dogs (n = 180). A subset (n = 15) of Hepatozoon-positive dogs with unusually high (> 800 H canis gametocytes/microL of whole blood) parasitemia was compared with dogs that had low parasitemia (n = 85) and with Hepatozoon-negative dogs (n = 180). Hepatozoon-positive dogs significantly differed from Hepatozoon-negative dogs in body temperature, total red blood cell count, hemoglobin concentration, hematocrit, and platelet count. Dogs with high H canis parasitemia significantly differed from those with low parasitemia in hemoglobin concentration, hematocrit, and total neutrophil count. Clinical findings from dogs with high H canis parasitemia included emaciation, lethargy, hyperglobulinemia, hypoalbuminemia, and increased serum alkaline phosphatase and creatine kinase activities. Findings at necropsy included hepatitis, pneumonia, and glomerulonephritis associated with H canis schizonts and extensive parasitism of bone marrow, spleen, and lymph nodes. Low hemoglobin concentration, low platelet count, and concurrent parvovirus infection together represented the best predictor variables for Hepatozoon positivity in dogs presenting to the hospital.

Triethylenetetramine dihydrochloride (trientine-2HCl, TJA-250), a copper chelating agent used to treat Wilson's disease, was administered orally to male and female F-344 rats for 4 or 8 weeks at dosages of 0, 100, 350 or 1200 mg/kg/day or for 26 weeks at dosages of 50, 175 or 600 mg/kg/day. 4 or 8-week study. Two males receiving 1200 mg/kg/day died during week 8 of treatment. In males receiving 1200 mg/kg/day during weeks 5 to 8 of treatment, body weight gain and food consumption were decreased and hunched posture and thin build were observed. During week 4 or 8 of treatment urinalysis revealed, for males receiving 100 mg/kg/day or animals receiving 350 mg/kg/day or more, increased electrolyte outputs possibly due to the hydrochloride nature of trientine-2HCl, with low plasma alkaline phosphatase activities evident in animals receiving 350 or 1200 mg/kg/day. After 4 and 8 weeks, and during 8 weeks of treatment, high lung weights and bronchiolar epithelium hypertrophy and broncho-alveolar pneumonia were recorded for animals receiving 1200 mg/kg/day, and submucosal acute inflammation within the glandular region of the stomach was recorded for males receiving 350 or 1200 mg/kg/day and in all treated female groups. 26-week study. One male receiving 175 mg/kg/day and three males receiving 600 mg/kg/day died, showing lung changes. The body weight gain of animals receiving 600 mg/kg/day was slightly decreased. Blood chemistry and urinalysis examinations showed changes similar to those indicated in the 4- or 8-week study. The low plasma copper concentrations seen in males receiving 600 mg/kg/day, the slightly low liver copper concentrations found in animals receiving 600 or 175 mg/kg/day and the high urinary copper concentrations found in all treated groups, are attributed to the pharmacological action of trientine-2HCl. Histopathology revealed a dosage-related incidence and severity of focal chronic interstitial pneumonitis accompanied by fibrosis of the alveolar walls in females receiving 175 mg/kg/day or more and all treated male groups, but no significant pathological changes in the stomach. Apart from the histological changes found in the lung, all the above changes were reversible. In conclusion, the NOAEL of trientine-2HCl in this 26-week study was considered to be 50 mg/kg/day for females and less than 50 mg/kg/day for males.

This study sought to identify any benefit of routine liver function tests (LFTs) in chronically ill, geriatric patients and to assess which patients require evaluation for abnormal LFT levels. A retrospective chart review was carried out on 268 consecutive patients (M:F = 1.2, mean age 77 years, range 61-98 years) presenting for acute care from a long-term care facility. All were without jaundice, right upper quadrant pain, pruritus, bruising, or signs of chronic liver disease. The degree of LFT abnormality (aspartate aminotransferase, alanine aminotransferase, total bilirubin, or alkaline phosphatase) during admission was compared to the clinical diagnosis at the time of discharge. The most common diagnoses were pneumonia, urinary tract infection, and peripheral or coronary disease in 186 (60%). Thirty-seven patients (14%) had elevated LFT levels on admission. The levels normalized within 2 days in 26 of these patients, 25 of whom had a history of vascular disease (96%). Of the 11 remaining patients, 4 had coexistent vascular disease (36%), and 5 had LFT levels twice normal (none with vascular disease) and underwent abdominal ultrasound. One patient had a common bile duct stone successfully extracted. Enzyme abnormalities were due to hepatitis B or medication use in 10 of 11 patients. No patient had liver biopsy. All but one of the 268 patients were discharged without further evaluation. Over one year of follow up, no patient returned for a liver-related problem. Based on these findings, only those patients with LFT levels that are twice normal and which do not normalize within 2 days warrant further evaluation. Transient LFT abnormalities may be due to decreased liver perfusion.

A 78-year-old man was diagnosed as leukocytosis in February 1994. Physical examination revealed marked hepatosplenomegaly. A peripheral blood examination disclosed 95,090/microliter leukocytes without hiatus leukemicus, 6.5 g/dl Hb, and 15.0 x 10(4)/microliter platelets. The neutrophil alkaline phosphatase score was 27, and serum VB12 was above 1,600pg/ml. IgG was identified as monoclonal immunoglobulin of type lambda. Bone marrow specimens demonstrated marked granulocytic hyperplasia. Neither the Philadelphia chromosome (Ph1) nor BCR gene rearrangement was detected; hence, the diagnosis of Ph1 (-) chronic myeloid leukemia (CML) was made. The patient was treated with hydroxyurea and low-dose VP-16 with no improvement, and died of pneumonia and sepsis in June 1995. This case was considered to be consistent with atypical CML (aCML) according to the FAB classification because monocytosis was not observed. It seems likely and interesting that the coexistent monoclonal gammopathy and aCML might have arisen from common abnormal hematopoietic stem cells.

We examined the effect of a single intravenous dose of flumetasone (SAID) and meloxicam (NSAID) treatment of calves with experimentally-induced localized lung inflammation on immunological and hematological variables such as total protein, gamma globulin, hemoglobin (Hb) concentrations, alkaline phosphatase activity, packed red cell volume (PCV), red blood cell (RBC) and white blood cell (WBC) counts. The influence of drug treatment on the phagocytic activity of WBC and bronchoalveolar lavage (BAL) cells and their ex vivo ability to produce interferon (IFN) and tumor necrosis factor (TNF) after induction with Newcastle disease virus (NDV), as well as on the development of PHA-induced skin delayed hypersensitivity reaction was also determined. Two days after the treatment of calves with experimentally-induced local lung inflammation with flumetasone (5 mg per calf), we observed a significant increase in WBC count, especially neutrophils, and a decrease in gamma globulin concentration, in the percent of blood phagocytic cells and their random migration. Flumetasone treatment also inhibited the development of skin delayed hypersensitivity reaction. In contrast, the treatment of calves with meloxicam (50 mg per calf) did not influence any hematological parameters or skin reactivity. Both drugs, flumetasone and meloxicam, influenced TNF production in ex vivo cultures of blood and BAL cells, inhibiting excessive TNF production induced by local lung inflammation. Contrary to TNF, the treatment of calves with meloxicam and flumetasone enhanced ex vivo IFN production in blood and BAL cells. Histological examination of lung tissue revealed that in control calves (those not treated with anti-inflammatory drugs) and in calves treated with flumetasone, symptoms of stromo-purulent inflammation of pulmonary tissue developed. However, in calves treated with meloxicam, only interstitial inflammation with a slight thickening of interalveolar septa and infiltration of lymphoid cells was observed. These results suggest that in this model of pneumonia, it is more appropriate to use a single dose of meloxicam, rather than flumetasone, to modulate lung inflammation.

Determination of the cellular profile of bronchoalveolar lavage fluid (BALF), lactate dehydrogenase (LDH) and alkaline phosphatase (ALP) appeared to be useful in monitoring pulmonary damage. The aim of this study was to investigate whether the cellular profile, LDH, its isoenzyme pattern and/or ALP in BALF are useful in the diagnostic work-up of patients with suspected pneumonia. The BALF specimens of 80 patients were studied. Group I consisted of patients with a pulmonary infection (n=33) and group II of patients without signs of a pulmonary infection (n=47). Differentiation between these two groups was based upon the results of microscopy and quantitative cultures. The absolute as well as relative numbers of polymorphonuclear neutrophils (PMNs) was significantly higher in group I compared to group II (p<0.0001). The absolute number of PMNs showed a sensitivity of predicting the correct group of 95.7% and a specificity of 84.8%. The LDH activity in BALF was significantly higher in group I than in group II (p<0.0001). The LDH4/LDH5 ratio in BALF was lower in group I compared to group II (p<0.0001) and appeared to be the best discriminator between the two groups with a sensitivity of 93.6% and a specificity of 93.9%. In conclusion, the number of polymorphonuclear neutrophils as well as the lactate dehydrogenase activity, particularly its isoenzymes, in bronchoalveolar lavage fluid appeared to be of potential practical value to distinguish between infectious and noninfectious pulmonary disorders.
