- Six non-compromised patients with cytomegalovirus (CMV) associated meningoencephalitis are described. CMV was isolated from the cerebrospinal fluid (CSF) in 2/4 cases, while the diagnosis was based on an 8-fold rise in CMV-specific serum IgG antibodies and intrathecal antibody production against CMV in one case. By the polymerase chain reaction (PCR) CMV DNA was detected in the CSF in 5/5 cases and in serum in 3/4 cases. In one patient who had an Influenza A infection, both CMV and Epstein-Barr virus DNA were detected by PCR in the CSF. In 4 patients possible triggering events could be identified. Symptoms and signs indicating a multifocal brain involvement were present in 4 patients. The outcome was generally favourable except for sequelae in form of slight dysphasia in one case.

- The degradation of phytate (inositol hexaphosphate) in rapeseed meal diet not containing phytase activity was studied in 15 growing ileum-fistulated pigs. Stomach and small intestinal degradation and total gastrointestinal degradation were compared. The effect of addition of calcium carbonate to the rapeseed meal diet at two levels (9.2 and 18.5 g/kg diet) was investigated. A commercial barley-wheat-soybean diet with intrinsic phytase activity was used as reference. Phytate and its hydrolysis products in diets, ileal digesta and feces were determined by HPLC ion-pair chromatography. Hydrolysis of phytate in the stomach and small intestine was 35-45% in pigs fed the rapeseed meal diet independent of calcium addition, and 65% in pigs fed the reference diet. Total gastrointestinal degradation of phytate in pigs fed the rapeseed diet was 97, 77 and 42% (P < 0.001) when calcium intakes were 4.5, 9.9 and 15 g/d, respectively; total gastrointestinal degradation was 72% in pigs fed the reference diet. The intestinal phytate degradation pattern, when rapeseed diet was fed, indicated the activity of an unspecific phosphatase, whereas that of the reference diet indicated intrinsic dietary phytase activity. We conclude that dietary supplementation of calcium carbonate decreases the phytate degradation in the colon of pigs, but not in the stomach and small intestine.
