چکیده
Yang et al, (1999) conducted a placebo-controlled, double-blind study to investigate the effects of seed and pulp oils of sea buckthorn on atopic dermatitis. Forty-nine atopic dermatitis patients took 5 g (10 capsules) of seed oil, pulp oil, or paraffin oil (control group) by mouth daily for 4 months. Patients treated with sea buckthorn seed oil had increased levels of linoleic, alpha-linoleic, and eicosapentaenoic acids in plasma lipids. In the seed oil group, after 1 month of supplementation, positive correlations were found between improvement of atopic dermatitis symptoms and an increase in proportions of alpha-linolenic acid in plasma lipids and neutral lipids. Patients treated with the pulp oil had increased levels of palmitoleic acid in plasma phospholipids and neutral lipids. No changes in the levels of triacylglycerols, serum total, or specific immunoglobulin E were detected. Yang et al (2000) conducted a second placebo-controlled study to investigate the effects of seed and pulp oil supplementation on the fatty acid composition of skin glycerophospholipids of patients with atopic dermatitis. Sixteen patients ate 5 g of sea buckthorn seed oil, pulp oil, or paraffin oil daily for 4 months. Skin fatty acids were analyzed before and after treatment. The seed oil slightly increased the proportion of docosapentaenoic acid and decreased the proportion of palmitic acid in ski glycerophospholipids. Pulp oil treatment slightly increased the proportion of stearic acid. The levels of the other fatty acids remained stable. Their results indicate that the fatty acid composition of the skin phospholipids is well buffered against a short-term dietary change. The results, however, do require conformation because of the small number of patients.
