Vitamin C and E supplementation hampers cellular adaptation to endurance training in humans: a double-blind, randomised, controlled trial.

In this double-blind, randomised, controlled trial, we investigated the effects of vitamin C and E supplementation on endurance training adaptations in humans. Fifty-four young men and women were randomly allocated to receive either 1000 mg of vitamin C and 235 mg of vitamin E or a placebo daily for 11 weeks. During supplementation, the participants completed an endurance training programme consisting of three to four sessions per week (primarily of running), divided into high-intensity interval sessions [4-6 × 4-6 min; >90% of maximal heart rate (HRmax)] and steady state continuous sessions (30-60 min; 70-90% of HRmax).

[Regional anesthesia in emergency cesarean section. Quality of epidural and spinal anesthesia].

From 1987 to 1989, 97.8% of non-elective caesarean sections at Innherred general hospital were performed under regional anaesthesia (N = 271). A retrospective analysis showed that the mean time from giving the anaesthetic until start of surgery was 28.

[Endoscopic biopsy of the small intestine in children].

As from 1983, endoscopy with biopsy in general anesthesia was used instead of the capsule suction method in children with suspected coeliac disease in a county hospital. A study was carried out to evaluate mean endoscopy time, duration of general anesthesia, complications and quality of biopsies. An ordinary Olympus GIF-Q endoscope (diameter 11 mm) was used in 17 patients, eight boys and nine girls.
