- Eating problems and nutritional status were studied in a consecutive series of patients who had had strokes. From this cohort, 32 subjects (mean age 73 years) with a hospital stay of 21 days or more are described. Eating problems were identified by direct participant observations of the patients' eating behavior, interviews on admission, inspections of the mouth, and discussions with the patients. Nutritional status was assessed by weight, triceps skinfold thickness (TSF), arm muscular circumference (AMC), plasma albumin, serum transferrin, and plasma prealbumin on admission and then weekly. Eating problems were identified in 27 patients. In a general linear hypothesis program, poor nutritional status 3 weeks after admission was found to be associated with (in decreasing order) low self-care performance, poor nutritional status on admission, male sex, intravenous energy-containing fluids, advanced age, paresis of the right arm, and eating problems. Factors other than eating problems seem to be important for undernutrition in patients with strokes during hospital stay. AD - Department

The development of somatic embryos in tissue-cultures initiated from immature embryos of Picea abies (Norway spruce)
- 1985

Journal article (peer-reviewed)abstract
- Embryos of Picea abies at various developmental stages were cultured on defined media supplemented with 2,4-dichlorophenoxyacetic acid (2,4-D) (10−5 M) and N6-benzyladenine (BA) (5×10−6 M). The immature embryos gave rise to a highly friable and embryogenic callus which could be maintained by subculture and contained polarized and organized structures (somatic embryos) consisting of long highly vacuolated cells at one end (suspensor) and a group of small meristematic cells at the other (embryonal end). These structures closely resembled the early stages of normal zygotic embryogeny. Upon further culture these structures formed a bipolar shoot-root axis with an independent and closed vascular system. In many instances either the shoot or the root meristems failed to differentiate. Embryogenic tissues obtained on agar media could be transferred to liquid media and maintained by subculture for at least 6 months. The development of somatic embryos was observed in the liquid cultures also.
