    Notes: Summary Acute ingestion of pure ethanol has been reported to delay gastric emptying and to enhance the propulsive movements of the intestine. The aim of the present study was to investigate the comparative effect of beer (7.0% v/v), white wine (7.5% v/v), ethanol (7.5% v/v), and water on the gastric emptying of a liquid test meal and on the gastrocaecal transit time of lactulose added to the test meal. Gastric liquid emptying was assessed by means of a nasogastric intubation technique using polyethylene glycol 4000 as the non-absorbable marker. The gastrocaecal transit time was evaluated by a hydrogen breath test. Beer (P〈0.001) and white wine (P〈0.05) significantly accelerated gastric emptying in comparison with ethanol of the same concentration. The gastrocaecal transit time was significantly shorter when the liquid meal was administered with beer compared with ethanol (P〈0.005) and water (P〈0.01). The constituents in beer and white wine responsible for our observations remain to be found.

    Notes: Summary The epidermal growth factor (EGF) and alpha-tumor growth factor are mitogenic proteins which bind to the EGF-receptor and may play a role in carcinogenesis or tumor progression. Our study investigated whether colorectal carcinomas and adenomas express altered levels of EGF-receptors or overproduce EGF-like activity by comparing histologically normal mucosa to carcinomas resected from the same patients. EGF-receptors were characterized by radioligand binding studies. Carcinomas contained unchanged or decreased levels of EGF-receptors in 13/16 and moderately increased levels in 3/16 patients as compared to normal mucosa. Adenomas obtained from 2 patients with familial polyposis coli and from a third patient with a coincident carcinoma had similar numbers of EGF-receptors as normal mucosa. EGF-like growth factors, in contrast, were significantly elevated in carcinoma extracts as compared to extracts from normal mucosa of the same patients. Adenomas did not contain elevated levels of EGF-like activity. We conclude that increased expression of EGF-receptors is infrequent in colonic adenocarcinomas. Increased production of EGF-like growth factors may frequently occur but seems to be associated with tumor progression rather than with premalignant lesions as represented by adenomas.

    Perioperative myocardial perfusion scintigraphy at rest with technetium 99m methoxyisobutylisonitrile before and after coronary bypass operations (1991)
    Springer
    European journal of nuclear medicine 18 (1991), S. 99-105

    ISSN: 1619-7089

    Notes: Abstract Eighteen patients were examined at rest by technetium 99m methoxyisobutylisonitrile (99mTc-MIBI) myocardial scintigraphy 1 day before and 1 week after aorto-coronary bypass operation with planar and single photon emission tomography (SPET) imaging. One day postoperatively, a planar scintigraph in the intensive care unit (ICU) was done. Inter-observer variability was 3.8% for all examinations and for SPET alone, 3.9%. The quality of the planar images taken under emergency conditions in the ICU was quite comparable with those taken under routine conditions. The postoperative myocardial infarction in a patient who died 6 days later could clearly be demonstrated. In 16.2% of all segments which were hypoperfused at rest on preoperative scintigraphy, an amelioration of perfusion could be shown in the 1 st week after the bypass operation.99Tc-MIBI proved to be a useful agent to assess perioperative perfusion, in the ICU as well as under standard conditions.
