Infection of 60 to 90% of neutrophils with the protozoa, Hepatozoon canis, was detected in 2 dogs. Clinical signs included lethargy, anorexia, and weight loss. Both dogs had severe anemia, leukocytosis, and thrombocytopenia as well as hypoalbuminemia, hyperglobulinemia, and high activities of serum alkaline phosphatase and creatine kinase. Both dogs were treated with imidocarb dipropionate and doxycycline. One dog recovered clinically, with disappearance of parasites from WBC. The other dog died, despite treatment. Necropsy revealed widespread dispersion of schizonts in the parenchymal tissues, but no involvement of skeletal muscle tissues. The disease syndrome that has been identified in the Texas Gulf region is characterized by gait abnormalities associated with multifocal pyogranulomatous myositis, thus, it is distinct clinicopathologically from the syndrome observed in these 2 dogs.

The 1.3 S biotinylatable subunit of Proprionibacterium shermanii transcarboxylase complex was fused to the C-terminus of the human neurokinin 1 receptor gene and introduced into the Semliki Forest virus expression vector pSFV1. RNA transcribed from pSFV1-NK1-biot and pSFV-Helper2 was coelectroporated into BHK cells permitting in vivo packaging of recombinant virus. Infection of BHK and CHO cells with SFV-NK1-biot virus yielded high level of the fusion receptor as detected by metabolic labeling, immunoblotting with streptavidin alkaline phosphatase and binding to substance P. Like native receptor, the biotinylated receptor fusion was able to stimulate Ca2+ mobilization in infected CHO cells, indicating functional coupling to guanine-nucleotide-binding proteins.

Risk factors for primary cerebral hemorrhage remain uncertain. The population-based Stroke Registry of Dijon provides data on the risk factors. Among residents of Dijon (France), 130 cases of primary cerebral hemorrhage hospitalized from 1985 to 1992 were matched with 130 controls by age and sex. The following data were collected: history of hypertension, alcohol consumption, tobacco consumption, history of coagulation disorder, diabetes mellitus, dyslipidemia, and infectious disease in the 7 days before admission. The following parameters were measured on admission: blood pressure, blood glucose, cholesterol, triglycerides, hematocrit, fibrinogen, prothrombin levels, platelet counts, prothrombin time, bilirubin, transaminases, gamma-glutamyltransferase, and alkaline phosphatase. Electrocardiogram and Doppler ultrasound examination of cervical arteries were performed. Statistical analysis was performed by means of relative risk ratio for paired samples when dealing with proportions, and Student's t test for quantitative variables. A stepwise discriminant analysis was carried out to establish the relative weight of the different risk factors and their discriminant values. Among the qualitative data, the significant factors were history of hypertension, alcohol consumption, cardiac arrhythmia, atherosclerosis of carotid arteries and a previous infectious disease in the 7 days before admission. Among the quantitative data, the significant factors were early hypertension, high blood glucose levels, high hematocrit, and low cholesterol levels, in the acute stage of the stroke. After multifactorial analysis, only two factors were significant: hypertension and low cholesterol levels. Our population-based case-control study showed that hypertension and low cholesterol levels are the two discriminant risk factors for both lobar and basal ganglia primary cerebral hemorrhage. Therefore, treatment of hypercholesterolemia may increase risk of cerebral hemorrhage.

In situ hybridization (ISH) provides a means for identifying viral genomes in the context of tissue pathology. We have developed a specific and sensitive ISH probe for the detection of cytomegalovirus (CMV) DNA in formalin-fixed, paraffin-embedded tissue sections. Digoxigenin-11-dUTP was incorporated into a 435-base pair fragment of the CMV Major Immediate Early (MIE) gene with use of the polymerase chain reaction (PCR). Hybridized probe was detected by reaction with antidigoxigenin antibody coupled to alkaline phosphatase and chromogenic substrates. This method has detected CMV infection in routine clinical specimens from a variety of tissue types, including colon, kidney, liver, and stomach. Infection in cells with and without characteristic inclusions is revealed with this probe. The background is so low that single infected cells are detected unambiguously. No cross-hybridization was observed with cells infected with other viruses of Herpesviridae. This approach may be useful for producing probes for the detection of other viral genomes in tissue sections.

We report the utility of a possible lymphocyte fraction of alkaline phosphatase (ALP band-10) activity in serum to predict human immunodeficiency virus type 1 (HIV-1) infection in children born to HIV-1-seropositive mothers. The presence of ALP band 10 in serum consistently correlated with HIV-1 infection status as judged by positive HIV-1 culture, two consecutive HIV-1 p24 antigen results greater than 30 pg/mL in serum, and the subsequent confirmation of seroconversion to HIV-1 antibody after clearance of maternal IgG anti-HIV-1 antibody ascertained between 15 to 24 months post partum. Infection with HIV-1 was correctly identified in 31 samples from 18 patients ranging in age between 0.1 to 10 years; the absence of similar infection was noted in 14 samples from nine patients who served as controls and whose serum samples did not exhibit ALP band-10 activity. This ability of serum ALP band-10 activity to predict HIV-1 infection status in children as young as 2 months may be useful as a surrogate marker for early identification of HIV-1 infection in infants born to HIV-1-seropositive women long before the clearance of maternal anti-HIV-1 antibodies can be ascertained.

Infection due to the Mycobacterium avium complex (MAC) is the most common opportunistic disease of bacterial origin among patients with AIDS in the United States. The incidence of disseminated disease due to MAC (DMAC) has risen dramatically in recent years. The risk of developing DMAC increases as the CD4+ lymphocyte count declines to < 100/mm3. Preliminary analyses of several studies suggest that gender, racial or ethnic group, and individual risk factors for human immunodeficiency virus infection do not influence the incidence of DMAC but that prior Pneumocystis carinii pneumonia, the development of severe anemia, or the interruption of antiretroviral therapy may increase risk. Both the respiratory and the gastrointestinal tracts probably serve as portals of entry for MAC. Colonization may potentiate the risk of DMAC but does not always precede dissemination. Patients with AIDS and DMAC have a shorter duration of survival than do those with AIDS but without DMAC. While treatment for DMAC may extend survival, no well-controlled, prospective, randomized clinical trial has documented this point. Most patients with AIDS and DMAC have disseminated multiorgan disease; the most frequently described symptoms include fever, night sweats, weight loss or wasting, diarrhea, and abdominal pain. The most commonly identified laboratory abnormalities are anemia and elevated serum levels of alkaline phosphatase. Localized disease syndromes related to MAC infection occur less often.

Hypophosphatasia is a congenital disease characterized by defective bone mineralization, deficiency of alkaline phosphatase (ALP) activity, increased excretion of the phosphoethanolamine (PEA) in the urine, and premature loss of the deciduous teeth. A male hypophosphatasia patient (aged 15 years 6 months) with premature exfoliation of the deciduous teeth was referred to our hospital because of severe periodontal destruction in the permanent dentition. Blood and urine tests as well as oral and periodontal examinations were performed. Serum antibody titers against 7 periodontopathic bacteria by the enzyme-linked immunosorbent assay (ELISA), monocyte and neutrophil chemotaxis measurements, and cellular immunity tests were also performed. Low levels of ALP in serum and PEA in the urine were found. Monocyte and neutrophil chemotaxis exhibited normal values. Slightly depressed CD2+, CD3+, and CD4+ and slightly elevated activity of NK cells were found. An elevated level of serum antibody to Porphyromonas gingivalis was observed. Oral radiographic examination showed a mirror pattern of alveolar bone loss which is similar to that seen in localized juvenile periodontitis. Periodontal treatment of this patient was carried out for 4 years. The severely affected sites, the lower right and left first molars and the upper right first molar, had to be extracted. However, the other sites were well maintained. The serum IgG level against P. gingivalis was decreased after 4 years of periodontal treatment. Infection with P. gingivalis was suspected to be associated with the destruction of this patient's hypophosphatasia, but other dental abnormalities such as abnormal enamel, dentin, and cementum formation may also have contributed to the periodontal pathology.

Two nontransformed revertants of HeLa cells, designated HA and HF, were isolated using a selection procedure based on prolonged retention of the fluorescent dye rhodamine 123 within the mitochondria of HeLa (ATCC CCL2) cells versus normal epithelial cells. Unlike the parental HeLa cells, the revertants expressed markedly reduced levels of the bone-liver-kidney, placental, and intestinal isoforms of alkaline phosphatase, exhibited a flat nonrefractile morphology, and failed to grow in suspension culture. The revertant clones had > 100-fold reduced cloning efficiencies in semisolid medium relative to HeLa cells and failed to induce s.c. tumors when injected into nude mice. Both revertant clones have retained nontransformed phenotypes after 5 years of continuous culture. Southern blot analyses performed with human papillomavirus 18-specific DNA probes indicated that the integrated viral sequences present in HeLa cells remained intact in the revertants. Furthermore, the level of the polycistronic mRNAs encoding the viral E6 and E7 oncogenes were comparable in the parental HeLa cell line and the revertants. Western blot analyses of immunoprecipitated human papillomavirus 18 E6 and E7 proteins further demonstrated that the levels of these viral oncoproteins were comparable in HeLa cells and revertants. Infection with helper-free, defective retroviruses that express E6, E7 or E6 and E7 oncogenes failed to retransform the revertants, suggesting that their nontransformed phenotype did not result from mutations in these viral oncogenes. Cell fusion experiments indicated that the revertant phenotypes of HA and HF cells resulted from mutations in cellular genes that activate one or more tumor suppressor genes.

In the period of 1989-1995 seven patients with amebic liver abscess were observed in Clinic of Infectious Diseases of Pomeranian Medical School in Szczecin. The diagnosis has been made on the base of epidemiological data, presence of intrahepatic defect by a scanning procedure of liver (ultrasonography, CT, scintigraphy) and positive serologic test for amebiasis. All patients were male of Polish nationality, 29-57 years old, who became ill after travel to Africa or India. Intestinal amebiasis was present only in two cases. Five patients had acute onset of disease and two chronic. The most common complaints included fever, abdominal pain, anorexia. A cough, chest pain, diarrhea or weight lose were less common. At physical examination paleness of skin, subjaundice, abdominal tenderness, hepatomegaly and sometimes pleural effusion have been observed. Laboratory tests revealed high RBS, leucocytosis and mild anemia. Slightly higher serum level of bilirubin, alkaline phosphatase were transient. Trophozoits of Entamoeba histolytica have been found in stool specimens of one only patient. Amebic antibodies tested with indirect hemagglutination (IHA) were present in all cases. Visual technics have shown abscess of 3 to 9 cm in diameter located at right liver lobe. Six patients have been treated with both chemotherapy (metronidazole or/and dehydroemetine) and "skin needle" aspiration. In two cases recrudescence of abscess has been observed after one and three years respectively. These two patients have been undergone second course of treatment with using not only needle aspiration and metronidazole/dehydroemetine but luminal agents as well.

CEMx174- and C8166-45-based cell lines which contain a secreted alkaline phosphatase (SEAP) reporter gene under the control of a tat-responsive promoter derived from either SIVmac239 or HIV-1(NL4-3) were constructed. Basal levels of SEAP activity from these cell lines were low but were greatly stimulated upon transfection of tat expression plasmids. Infection of these cell lines with simian immunodeficiency virus (SIV) or human immunodeficiency virus type 1 (HIV-1) resulted in a dramatic increase in SEAP production within 48 to 72 h that directly correlated with the amount of infecting virus. When combined with chemiluminescent measurement of SEAP activity in the cell-free supernatant, these cells formed the basis of a rapid, sensitive, and quantitative assay for SIV and HIV infectivity and neutralization. Eight of eight primary isolates of HIV-1 that were tested induced readily measurable SEAP activity in this system. While serum neutralization of cloned SIVmac239 was difficult to detect with other assays, neutralization of SIVmac239 was readily detected at low titers with this new assay system. The neutralization sensitivities of two stocks of SIVmac251 with different cell culture passage histories were tested by using sera from SIV-infected monkeys. The primary stock of SIVmac251 had been passaged only twice through primary cultures of rhesus monkey peripheral blood mononuclear cells, while the laboratory-adapted stock had been extensively passaged through the MT4 immortalized T-cell line. The primary stock of SIVmac251 was much more resistant to neutralization by a battery of polyclonal sera from SIV-infected monkeys than was the laboratory-adapted virus. Thus, SIVmac appears to be similar to HIV-1 in that extensive laboratory passage through T-cell lines resulted in a virus that is much more sensitive to serum neutralization.
