The Subject

In persons with anorexia nervosa (AN), compulsive exercise and osteopenia are common symptoms. Although treatment of osteopenia besides weight regain is lacking, maximal strength training (MST) has been found to be effective in other populations. Such training has not been prescribed to those with AN due to uncertainty of tolerance. We therefore examined use of MST in a woman with long-standing AN, osteopenia, menstrual dysfunction, and compulsive exercise. The MST intervention consisted of four exercises: three sets of five repetitions maximum (RM), 3 times per week for 16 weeks. We examined muscle strength, bone mineral density (BMD), AN psychopathology, and compulsive exercise at baseline, posttest, and 6-month follow-up. Attendance rate was 100%. The subject improved muscle strength by 20% to 40%. BMD in lumbar spine improved by 4% to posttest, and by 8% from baseline to 6-month follow-up. The BMD T-scores shifted from values classified as osteopenic to normal values throughout the course of the intervention, despite continuance of menstrual dysfunction and lack of weight gain. No changes in AN psychopathology or levels of compulsive exercise were detected. Perceived psychological benefits including new bodily experiences were self-reported by the subject, emphasizing the importance of close follow-up by competent instructors.

Many patients with eating disorders have menstrual dysfunction. In patients with anorexia nervosa, amenorrhea has been linked to weight loss. However, many patients with bulimia nervosa, even those of average or greater than average weight, also experience menstrual abnormalities, including amenorrhea. It was hypothesized that low weight per se is not responsible for menstrual dysfunction in patients with eating disorders. First, 16 patients with bulimia nervosa of average weight and 29 patients with cystic fibrosis of below average weight of similar menstrual age were compared. Of the patients with bulimia nervosa, 11 (73%) had had secondary amenorrhea at some time compared with 8 (28%) of the patients with cystic fibrosis (P < .01). At the time of study, 6 (40%) of the patients with bulimia nervosa and 21 (78%) of the patients with cystic fibrosis were having regular cycles (P < .01). Next 18 patients with anorexia nervosa were compared with 18 patients with cystic fibrosis matched for weight and menstrual age. Although 18 (100%) of the patients with anorexia nervosa had had secondary amenorrhea, only 6 (33%) of the patients with cystic fibrosis had amenorrhea. Although only 1 (6%) of the anorexia nervosa group was currently having regular cycles, 14 (78%) of the patients with cystic fibrosis were (P < .0001). Closer approximation to ideal body weight was associated with regular menses only in the cystic fibrosis group. Exercise did not appear related to regularity of menstruation in any group. Body weight is not the major factor responsible for menstrual abnormalities in patients with eating disorders.

Vacuolated Cytoplasm

Vacuolated cells in the liver of young rats were studied by light and electron microscopy following the administration of vitamin A (200 units per gram of body weight). Their characteristics were compared with similar cells found in untreated animals.In rats given vitamin A, cells with vacuolated cytoplasm were a prominent feature. These cells were found mostly in a perisinusoidal location, although some appeared to be in between liver cells (Fig. 1). Electron microscopy confirmed their location in Disse's space adjacent to the sinusoid and in recesses between liver cells. Some appeared to be bordering the lumen of the sinusoid, but careful observation usually revealed a tenuous endothelial process separating the vacuolated cell from the vascular space. In appropriate sections, fenestrations in the thin endothelial processes were noted (Fig. 2, arrow).

Gas Exposure

Chronic exposure to nitrogen dioxide in rodents has shown that injury reaches a maximum after 24 hours, and a reparative adaptive phase follows (1). Damage occurring in the terminal bronchioles and proximal portions of the alveolar ducts in rats has been extensively studied by both light and electron microscopy (1).The present study was undertaken to compare the response of lung tissue to intermittent exposure to 10 ppm of nitrogen dioxide gas for 4 hours per week, while the hamsters were on a vitamin A deficient diet. Ultrastructural observations made from lung tissues obtained from non-gas exposed, hypovitaminosis A animals and gas exposed animals fed a regular commercially prepared diet have been compared to elucidate the specific effect of vitamin A on nitrogen dioxide gas exposure. The interaction occurring between vitamin A and nitrogen dioxide gas has not previously been investigated.
