    Notes: Guinea keets, reared to 12 wk on a modified turkey starter and grower diet, were processed like broilers and thigh and breast meat samples analyzed. Proximate analysis for breast and thigh meat without skin was: dry matter 25.4 and 24.0%; protein 22.7 and 19.4%; hexane extractables 0.86 and 2.2%; and ash 1.06 and 1.05% respectively. Total cholesterol in breast meat was 40.6 mg/100g raw tissue, and 62.1 mg in the thigh. Also included were analyses for Na, K, Ca, Mg, P, thiamin, riboflavin, niacin, pantothenic acid and the fatty acid profiles of the meat and skin. Guinea meat was found to be lower in fat, sodium and cholesterol and higher in potassium, phosphorus, thiamin, riboflavin, niacin and vitamin B6 than broiler meat.

    The “air enema” in acute colitis (1983)
    Springer
    Abdominal imaging 8 (1983), S. 61-65

    Notes: Abstract The plain abdominal radiograph is an important investigation in acute colitis, but may fail to demonstrate the state of the colon owing to a lack of intracolonic gas. The extent of the colitis can be demonstrated by introducing air directly into the large bowel; the air also provides sufficient contrast to distinguish a granular from an ulcerated mucosa. The “air enema” may be used as an alternative to an unprepared barium enema. Its accuracy has been established by comparison with an unprepared barium enema in 10 patients with acute colitis.

    Calcium homeostasis and bone pathology in magnesium deficient rats (1980)
    Springer
    Calcified tissue international 31 (1980), S. 231-238 
    Details
    ISSN: 1432-0827
    Keywords: Magnesium ; Bone ; Calcium ; Parathyroid gland

    Notes: Summary Calcium homeostasis and bone pathology were studied in weanling rats fed a low (70 ppm) magnesium diet for 2–21 days. The rats developed significant, progressive hypercalcemia after 6 days on the diet. The increase in blood calcium was accompanied by progressive hypoactivity of the parathyroid gland (PTG), as determined by histologic and morphometric analyses. Thus hyperactivity of the PTG could not have been responsible for the hypercalcemia observed. Histologic examination of femora and humeri from magnesium-deficient rats showed progressive subperiosteal hyperplasia, consisting of undifferentiated osteoprogenitor cells and fibrous tissue, after 7 days of deficiency. The presence of unmineralized osteoid tissue in the metaphyses indicated that mineralization was not proceeding normally. The alterations in differentiation of osteoprogenitor cells, together with the failure of mineralization, resulted in significantly lower rates of bone formation (as measured by fluorochrome labeling) in the magnesium-deficient rats. Basophilic cementing lines and inactive osteocytes in the cortices of bones from magnesium-deficient rats indicated that bone resorption was also severely reduced in magnesium deficiency. We postulate that bone magnesium depletion (66% by day 21) has a direct negative effect on osteoblastic and osteocytic activity, and may explain, in part, the decreased responsiveness of bone to parathyroid hormone (PTH) that has been observed in magnesium-deficient animals.

    Correlations between defined sigmoidoscopic appearances and other measures of disease activity in ulcerative colitis (1982)
    Springer
    Digestive diseases and sciences 27 (1982), S. 533-537 
    Details

    Notes: Abstract It has been widely assumed that the activity of ulcerative colitis is related to differences in mucosal appearances seen at sigmoidoscopic examination. We have tested this assumption by making comparisons of the symptoms and clinical signs associated with three reproducible appearances of the rectal mucosa. By cross-tabulating 222 observations of each of 10 symptoms and signs with these sigmoidoscopic appearances it has been shown that the subdivision of hemorrhagic mucosae into those which bleed spontaneously and those which bleed only on light touching or scraping is meaningful clinically. Sigmoidoscopic appearances seemed to correlate better with clinical disease activity than histological assessment, even when quantitative, of mucosal biopsies. On the basis of this study, four variables have been suggested which, in addition to the sigmoidoscopic appearances, could form the basis of regular clinical assessment or scoring.

    Macroscopic lesions in dysplasia and carcinoma complicating ulcerative colitis (1983)
    Springer
    Digestive diseases and sciences 28 (1983), S. 18-26 
    Details
    ISSN: 1573-2568
    Source: Springer Online Journal Archives 1860-2000
    Topics: Medicine
    Notes: Abstract Visible changes associated with dysplasia or carcinoma have been assessed in 62 colectomy specimens from patients with ulcerative colitis. In 34 colectomy specimens with one or more carcinomas, there were 51 visible carcinomas and 65 macroscopic dysplastic lesions; only one carcinoma was found in flat mucosa. Among 28 specimens with microscopic dysplasia but no carcinoma, eight contained no visible dysplastic lesion, and the remaining 20 contained a total of 40 polypoid or elevated dysplastic areas. In 32 operative specimens removed for long-standing chronic colitis without dysplasia or carcinoma, nine contained visible inflammatory polypoid lesions. On radiological or endoscopic examination of the colon in long-standing colitis close attention should be given to the identification and biopsy of polyps, elevated nodular areas or plaques, strictures, and isolated ulcers. It is likely that colectomy specimens with visible polypoid or elevated dysplastic lesions will contain a carcinoma more often than those removed for dysplasia in flat mucosa.

    Polymorphonuclear leukocyte function in ulcerative colitis and Crohn's disease (1983)
    Springer
    Digestive diseases and sciences 28 (1983), S. 236-248 
    Details
    ISSN: 1573-2568

    Topics: Medicine
    Notes: Abstract The aim of this study was to determine whether polymorphonuclear leukocyte chemotaxis, adhesion, and electrophoretic mobility were altered in inflammatory bowel disease and whether such alterations could be related to prior ingestion of immune complexes. Polymorphonuclear leukocytes from patients with ulcerative colitis and Crohn's disease showed significantly impaired stimulated migration (P〈0.05), increased adhesiveness (P〈0.01 in ulcerative colitis,P〈0.001 in Crohn's disease), and reduced electrophoretic mobility (P〈0.02 in ulcerative colitis,P〈0.001 in Crohn's disease) compared with healthy controls. The disease control of patients with rheumatoid arthritis demonstrated reduced stimulated migration (P〈0.025) but normal adhesion. Preincubating normal cells in inflammatory bowel disease sera suggested that the altered migration and adhesion were due to circulating serum factors. Circulating immune complexes, detected by the C1q PEG binding assay, were present in 12.5% of patients with ulcerative colitis and 30% with Crohn's disease. Direct immunofluorescence of polymorphonuclear leukocytes suggested binding and/or ingestion of complexes in 57% of patients with ulcerative colitis, and 67% with Crohn's disease. There was a dorect correlation between positive immunofluorescence and impaired cell migration in ulcerative colitis (P〈0.05), but no such relationship was found in the other parameters of polymorph function.
