Screening for occult gastrointestinal bleeding in hospital patients.
Stools have been tested for occult gastrointestinal bleeding in 278 outpatients and 170 hospital inpatients using the Haemoccult and Haemastix methods. Seventeen outpatients (6.1%) and 42 inpatients (24%) were positive with the Haemoccult technique. Thirty-three outpatients (11.9%) and 93 inpatients (54.7%) were positive with the Haemastix test. Following investigation of the Haemoccult-positive patients, only 2 cases (3.4%) were considered false positive. However, the false positive rate with Haemastix was 22.9% which is unacceptable in a screening test. Haemoccult may be useful as a screening test for asymptomatic general practice patients, but a test of greater sensitivity is needed for hospital patients.

Induction of steroid 21-hydroxylase/beta-galactosidase transgene expression by unilateral adrenalectomy.
Unilateral adrenalectomy was used to induce compensatory growth in the contralateral adrenal gland of transgenic mice bearing a steroid 21-hydroxylase promoter/beta-galactosidase reporter (21-OHase/beta-gal) transgene, in which 6.4 kb of 5'-flanking sequence of the mouse steroid 21-OHase A gene are linked to a LacZ reporter gene. 48 hours following removal of the right adrenal gland, the left gland of transgene-positive mice showed a 4.5 fold increase in specific activity of the beta-gal reporter, compared to the right gland, while left glands from sham-operated transgene-positive and unilateral adrenalectomized transgene-negative mice showed no such increase. The increased specific transgene reporter activity, relative to total adrenal gland protein, must result from up-regulation of transgene expression, rather than from the compensatory increase in adrenocortical mass. This suggests that elements regulating trophic hormone-mediated 21-OHase gene expression in vivo are located within 6.4 kb of the 21-OHase gene transcription start site.
