چکیده
Results LSJ, a 13-years old Brazilian girl has complained of urticaria and asthma about 40 minutes after ingesting salty boiled beetroot on a meal. She had a previous history of wheezing until she was five years old. Seric-specific IgE to beetroot and other foods were negative, as well as to latex, bee, wasp and ant. She was sensitized only to house dust mite. Boiled and raw beetroot prick to prick were also negative (histamine resulted 4mm) but a food challenge with boiled beetroot resulted positive after 30 minutes with generalized hives, throat tightness and bronchospasm. Symptoms were controlled with intramuscular epinephrine, inhaled beta-2-agonists and intravenous corticosteroids. She was advised for a diet free of beetroot and she has had no symptoms for the last 8 months.

متن کاملThe location of acid invertase activity and sucrose in the vacuoles of storage roots of beetroot (Beta vulgaris).
Vacuoles were isolated from freshly cut slices of the storage roots of beetroot (Beta vulgaris), and from slices that had been washed in aerated water for 1-3 days. The unique vacuolar location of betanin permitted the use of a correlative method to determine whether sucrose and acid invertase were located in the vacuoles. The specific content (the activity of the enzyme or amount of substrate ...
