    Notes: Abstract During an 8-year period, 238 barium double-contrast studies performed in 162 patients with continent ileostomy reservoirs who had signs and symptoms of late complications (malfunction of the valve, non-specific inflammation of the mucosa, stenoses, hernias, and fistulas) showed radiologic abnormalities. The aim of the present study is to depict the radiologic findings in patients with late complications of continent ileostomy reservoirs. With radiologic examination, the correct diagnosis of valve malfunction was made in 96% of patients with surgically proven valve defects. We were able to differentiate between various types of valve dysfunction and complications related to the fixation of the reservoir to the abdominal wall. Inflammatory mucosal changes and fistulas of the reservoir and the afferent ileal segment were depicted with a high degree of accuracy. Barium double-contrast radiologic examination proved to be very valuable in the work-up of patients with dysfunction of continent ileostomy reservoirs. The method was of particular value in assessing the cause of valve dysfunction and in the appraisal of the afferent ileal segment.

    Notes: Abstract The aim of the present study is to describe the radiologic methods used to study continent ileostomy reservoirs and to depict the normal radiologic features and variations identified by these procedures. During an 8-year period, 408 double-contrast studies were performed in 261 patients. The present study comprises 170 examinations in 99 patients with normal findings. A high-density barium contrast medium and air were used. Modest variation in the size and shape of the reservoirs was observed. The mucosal pattern of the reservoirs resembled that of the ileum but the folds were slightly wider. The continence-providing valves were 3–5 cm long and had a diameter of 2.5–4.0 cm. The diameter of the afferent ileal segments was usually slightly larger than that of more proximal ileal segments, with an upper limit of approximately 4 cm. The efferent ileal segments generally had a straight course without widening or outpouches. Retrograde barium double-contrast examination is a satisfactory method for the evaluation of continent ileostomy reservoirs. Here we define the range of normal variations of such reservoirs as seen on retrograde double-contrast radiologic examinations.

    Inheritance of oilseed rape (Brassica napus) RAPD markers in a backcross progeny with Brassica campestris (1996)

    Notes: Abstract   Different cultivars/transgenic lines of oilseed rape (Brassica napus) were crossed (as females) with different cultivars/populations of Brassica campestris. All cross combinations produced seed, with an average seed set per pollination of 9.8. Backcrossing of selected interspecific hybrids (as females) to B. campestris resulted in a much lower seed set, average 0.7 seed per pollination. In the single backcross progeny where a large enough population (92 plants) was obtained for analysis, 33 B. napus-specific RAPD markers were investigated to determine the extent of transfer of oilseed rape genetic material into this population. Markers were transferred to the backcross generation with frequencies ranging from 26% to 91%. Almost all of the markers (30/33) were transferred in a frequency not significantly different from 50%. Analysis of the pairwise segregation of markers revealed that 23 markers could be assigned to six linkage groups, most probably reflecting six B. napus C-chromosomes. The presence of backcross plants with recombinant genotypes suggests that complex genetic processes can take place during interspecific hybridisation and backcrossing in these Brassica species. The implications of our results for the possible choice of integration sites of transgenes in oilseed rape are discussed.

    Inheritance of rapeseed (Brassica napus)-specific RAPD markers and a transgene in the cross B. juncea x (B. juncea x B. napus) (1995)

    Notes: Abstract We have examined the inheritance of 20 rapeseed (Brassica napus)-specific RAPD (randomly amplified polymorphic DNA) markers from transgenic, herbicide-tolerant rapeseed in 54 plants of the BC1 generation from the cross B. junceax(B. junceaxB. napus). Hybridization between B. juncea and B. napus, with B. juncea as the female parent, was successful both in controlled crosses and spontaneously in the field. The controlled backcrossing of selected hybrids to B. juncea, again with B. juncea as the female parent, also resulted in many seeds. The BC1 plants contained from 0 to 20 of the rapeseed RAPD markers, and the frequency of inheritance of individual RAPD markers ranged from 19% to 93%. The transgene was found in 52% of the plants analyzed. Five synteny groups of RAPD markers were identified. In the hybrids pollen fertility was 0–28%. The hybrids with the highest pollen fertility were selected as male parents for backcrossing, and pollen fertility in the BC1 plants was improved (24–90%) compared to that of the hybrids.
