Twelve pigs which averaged 13.7 kg were randomly allotted from litters to a corn-soybean meal grower diet containing 0, 20, or 200 ppm of polybrominated biphenyls (PPB). During a 16-week growth trial, average daily gain (kg), average daily feed (kg) and feed/gain for pigs on diets containing 0, 20, or 200 ppm of PBB, respectively, were 0.82, 2.45, 2.99; 0.67, 1.88, 2.79; 0.45, 1.23, 2.70. Mean daily gain differences between all lots were highly significant (p < 0.01). Blood from each pig was withdrawn biweekly through the first 8 weeks of the trial and at 4 week intervals thereafter. Hemoglobin and hematocrit differed significantly only at the 6 weeks bleeding, being reduced in pigs receiving 200 ppm of PBB. Erythrocyte reduced glutathione concentration and glutathione peroxidase activity were not significantly influenced by level of dietary PBB. Serum lactic dehydrogenase activity was significantly higher in control pigs than in either PBB supplemented lots at 16 weeks. There was no significant influence of PBB upon serum glutamic oxaloacetic transaminase, serum alkaline phosphatase or serum creatine phosphokinase. Based on these enzyme assays, PBB produced no evidence of significant necrosis of liver, myocardium, or skeletal muscle. There was no consistent effect of dietary PBB upon total serum protein concentration or electrophoretic profile. Pigs on either level of PBB did not have overt clinical signs of toxicity during the 16-week test period with the exception of a dermatosis on the ventral surface of two of the pigs receiving 200 ppm of PBB. There was a marked increase in liver weight of pigs receiving either level of dietary PBB. Heart, kidney, and adrenals of pigs receiving either level of dietary PBB were heavier as a percent of body weight than that of control pigs. Fat retention of PBB and urinary and fecal PBB excretion were significantly affected by dietary PBB level. Grossly, the glandular portion of the stomach appeared somewhat hyperplastic in pigs on 200 ppm of PBB. Two pigs which had received 200 ppm of PBB were placed on the control diet and over the next 14 weeks normal growth rate occurred. One of these pigs was killed and organ weights were normal. The other pig, a gilt, came into estrus. She was bred and conceived. At the end of gestation, four pigs were born. Three survived and grew normally; the one death at birth examined at gross necropsy did not reveal changes in organ size or other tissue alterations.

Clinical and epidemiologic examinations of 260 workers engaged in enzyme production revealed the structure of skin disease incidence: mycoses--31%, atopic dermatitis--19%, contact dermatitis--9%, allergic, dermatitis--5%. The majority of these skin diseases were associated with hyperphosphatemia and monoaminoxidase (MAO) depression. Changes of alkaline phosphatase and MAO activities, serum albumins and gamma-globulins may be considered as sensitive markers of disease.

Patients with chronic venous insufficiency show typical glomerulum like alterations of cutaneous capillaries. Objective of this study was to determine any changes of the alignment of pericytes around cutaneous capillaries in CVI patients. Skin biopsies from the area of the medial malleolus were taken from 42 patients with CVI, 5 healthy individuals and 11 cadavers without history of CVI. Sections were stained with HHF35, anti alpha and gamma muscle actin with the avidin-biotin-peroxidase method (ABC) and anti vimentin with the alkaline phosphatase anti-alkaline phosphatase technique (APAAP). The stage of stasis dermatosis was assessed and sections were examined for pericyte changes. Among the collective of 42 patients with CVI, 31 patients showed slight or severe pericyte changes, 11 patients were without changes. None of the sections from cadavers or healthy patients showed any pericyte changes. Pericytes are among other functions possibly involved in microvasculature regulation and wound healing. Thus destruction of the pericyte envelope might lead to microcirculatory dysfunction. This could be one of the causes that lead to leg ulcers in CVI.

To demonstrate an as yet merely postulated generalized osteopathy in psoriatics, the serum calcium level, the alkaline phosphatase in the serum and the urinary excretion of hydroxyproline were evaluated in 24 patients with Ps and 24 patients with PA. Moreover, the bone bioptates from 25 patients with PA and 10 patients with Ps were examined histologically and measured morphometrically. The investigations provide evidence for the existence of a generalized "latent" osteopathy in terms of an elevated bone turnover rate without loss of bone volume (high turnover remodelling) in both patients with PA as well as those with Ps without arthritis. As a pathogenetically essential factor shared by dermatosis and "osteopathy", latent vitamin D deficiency and/or D hormone resistance is discussed.

A newly recognized disease in dogs, ulcerative dermatosis associated with diabetes mellitus (diabetic dermatopathy), was diagnosed in 2 dogs with pancreatic endocrine tumors that had immunohistologic evidence of glucagon production. Dogs developed diabetes mellitus in the later stages of the illness, months after the skin disease was first observed. Liver disease was identified and characterized by high serum alkaline phosphatase and alanine transaminase activities. Clinically, erythema and crusting involved the footpads, the face, perioral and genital skin, and ventrum. Histologically, skin lesions were intercellular and intracellular edema and necrosis of the upper half of the epidermis and diffuse parakeratosis. Clinically and histologically, skin lesions closely resembled necrolytic migratory erythema of people, a skin disease that usually is associated with a glucagon-secreting pancreatic endocrine tumor and diabetes mellitus (glucagonoma syndrome): The morphologically descriptive term, superficial necrolytic dermatitis, was preferred over the previously proposed names hepatocutaneous syndrome and diabetic dermatopathy, which each connote only a single feature of the disease.

In order to make evident an up to now only postulated generalized osteopathy in psoriatics in 24 patients with psoriasis and 24 patients with psoriatic arthritis the serum-calcium levels, the alkaline phosphatase in the serum and the excretion of hydroxyprolin in the urine were determined. Moreover, the bone bioptates of 25 patients with psoriatic arthritis and 10 patients with psoriasis were histologically examined and morphometrically measured, respectively. The examinations give evidence for the presence of a generalized "latent" osteopathy in the sense of an increased bone turnover rate without loss of bone volume (high turnover remodeling) in patients with psoriatic arthritis as well as in those with psoriasis without arthritis. As a common pathogenetically significant factor for dermatosis and osteopathy a latent vitamin D deficiency and a D-hormone resistance is discussed.

The coexistence of a T-cell lymphoma with a myelodysplatic syndrome seems to be exceptional. In the case reported here the diagnostic problems raised by the appearance of cutaneous nodules in a patient with chronic myeloid leukaemia (CML) were solved by histo-immunological examinations. A 70-year old male patient had been presenting since 1976 with a psoriasis-like skin disease. He was first seen at the Argenteuil hospital in 1984. Physical examination showed psoriasiform finger-like erythemato-squamous lesions, infiltrated plaques and an ulcerated tumoral swelling of the right elbow. A diagnosis of mycosis fungoides was made on histological and immunological examination results. At histology, this epidermotropic lymphoma was peculiar in that the atypical infiltrate was clearly centred on vessels. Electron microscopy confirmed that the vascular walls were invaded by the mycosis cells. Additional examinations showed hyperleucocytosis and myelaemia which were rapidly attributed to a chronic myelocytic leukaemia since the Philadelphia chromosome was present and the leucocytes had a low alkaline phosphatase score. Bone marrow biopsy disclosed a myeloproliferative syndrome of the CML type. Biopsy of a right axillary lymph node showed myelocytic infiltration associated with dermopathic lymphadenitis. There were no circulating Sezary cells, and a search for extension proved negative. From May, 1984 to June, 1985 the patient's CML was treated with busulfan which produced blood and bone marrow remission. The skin lesions were treated first with mechlorethamine, then with topical corticosteroids. Superficial electron therapy was applied to the tumoral lesions.(ABSTRACT TRUNCATED AT 250 WORDS)

The origin of pulmonary multinucleate giant cells (MGC) in porcine dermatosis vegetans was studied in six Norwegian Landrace pigs ages 4 (male), 5 (female), 6 (female), 10 (female), and 12 (one male, one female) weeks, using an avidin biotin peroxidase and alkaline phosphatase complex immunohistochemical method on sections of formalin- and ethanol-fixed and frozen tissue specimens. Well-characterized, commercially available antisera/monoclonal antibodies to keratin, vimentin, lysozyme, a monocytic antigen, and a myelomonocytic antigen were used. The immunoreactivity to intermediate-sized filaments in MGC was negative for keratins and positive for vimentin. In addition, a positive reaction was found in alveolar macrophages, chondrocytes, fibrocytes, alveolar lymphocytes, and granulocytes in ethanol-fixed tissue. Marked masking was observed in formalin-fixed tissue. Antilysozyme antiserum gave a positive cytoplasmic reaction in alveolar macrophages and MGC, although the reaction was variable in ethanol-fixed tissue. In trypsinized formalin-fixed tissue, a moderate and more consistent cytoplasmic reaction was observed in alveolar macrophages and MGC. Two monoclonal antibodies that identify human cells of the MMS, EMB 11 and Mac 387, were negative for EMB 11 in ethanol-fixed and frozen sections, whereas Mac 387 showed a positive and specific cytoplasmic immunoreaction in alveolar macrophages and small MGC in ethanol- and formalin-fixed tissue. Pulmonary MGC in dermatosis vegetans are derived from mesenchymal cells, and substantial evidence is provided in support of a monocyte/macrophage origin based on a positive reaction for lysozyme and a myelomonocytic antigen. The importance of adequate fixatives for immunohistochemical demonstration of cell-specific markers is clearly shown.

In this study we investigate the expression of the low affinity immunoglobulin E (IgE) receptor (Fc epsilon RII) on plastic-adherent leucocytes from patients with atopic dermatitis (AD). Peripheral blood mononuclear cells were obtained from patients with AD, normal controls (and in one study from a group of atopic asthmatic patients). Monocytes were separated by 2-h adherence to plastic. These cells were then cultured for up to 7 days. Cells were harvested at time 0 (after adherence), and after 5 and 7 days culture, and cytospins were prepared. The proportion of cells expressing the phenotype of antigen presenting cells (monoclonal antibodies (mAb) RFD1+), and mature phagocytes (mAb RFD7+) together with CD23, were evaluated using combination staining with immunoperoxidase and alkaline phosphatase anti-alkaline phosphatase methods. It was found that a significantly larger proportion of circulating adherent cells in AD patients expressed the RFD1 antigen, and that increases in the proportion of these adherent cells expressing RFD1 or RFD7 occurred faster as cells matured in culture, when compared with cells obtained from normal controls. By day 7, however, equivalent proportions of RFD1+ and RFD7+ cells were present in AD and control cultures. None the less, expression of the CD23 molecule was consistently present on a larger proportion of both RFD1+ and RFD7+ cells from AD patients compared with controls. The raised proportion of circulating RFD1+ cells found in AD was not present in samples from atopic asthmatics, while the raised expression of CD23 on these cells occurred in samples from both these groups. These data support the suggestion that abnormalities in peripheral blood adherent cell phenotype, maturation, and CD23 expression, occur in AD patients. Some of these observations may be related to atopy in general rather than being specific for this skin disease.

We report a case of acute febrile neutrophilic dermatosis, Sweet's syndrome, associated with chronic myelogenous leukemia (CML) in which we found rearrangement of the bcr gene in DNA obtained from a skin lesion as well as in blood DNA by Southern blot analysis. This indicated the presence of CML cells within the skin lesion. To our knowledge, this is the first report in which the presence of CML cells is shown within skin lesions of Sweet's syndrome. In our patient, leukocyte alkaline phosphatase activities returned to normal levels when he was suffering from Sweet's syndrome and decreased again to below normal levels after it subsided. Whether the normalization of leukocyte alkaline phosphatase activity is common among CML patients with Sweet's syndrome remains to be determined.
