Atopic dermatitis (AD) typically develops in patients with a history of allergic ailments, and is characterised by an itchy, inflammatory skin condition with scaling, lichenification, papules, excoriations and pruritus. In AD patients a chronic relapsing inflammatory condition is seen, associated with IgE hyper production. AD flares are largely triggered by environmental factors. However, the exact etiology of AD is unclear and there is a pressing need for new treatment regimens as AD is a chronic condition and requires long term treatment. Historically Aloe has been used to treat skin conditions as well as a variety of other diseases. To further explore the pathogenesis and treatment of AD, Balb/c mice were sensitized and challenged with 2,4-dinitrochlorobenzene (DNCB) for atopic dermatitis induction. Thereafter, mice were treated with either Aloe ferox or Aloe vera applied daily on the dorsal skin for 10 consecutive days. A placebo gel was used for the control mice. Blood was collected at the end of the treatment period and serum IgE levels measured. Serum IgE levels were significantly lowered in the Aloe ferox group than in the Aloe vera group. This study demonstrated Aloe’s immunoregulatory potential for alleviating atopic dermatitis through influencing of Th2 cell activation. / Dissertation (MSc)--University of Pretoria, 2013. / gm2014 / Pharmacology / unrestricted
