    Notes: The wealing response of human skin to dimethyl sulphoxide (DMSO) has been quantified. Concentrations of 90%, 95%, and 100% were applied for 5 min to circular areas 8 mm in diameter. Wealing was scored on a five-point scale after 10 min.Marked individual variations were found. Wealing was strongly influenced by body region and was dose-dependent. The intensity of the reaction paralleled that to other irritants and was dependent mainly on thickness and integrity of the horny layer. The DMSO test is a simple, quick way to assess the barrier function of the stratum corneum.

    Notes: The occurrence of low molecular weight (〈 500 dalton) eosinophil chemotactic factor (ECF) was studied in the blister fluid of patients with various dermatological diseases by an in vitro chemotaxis method. After chromatographic separation of the test substance on a small Sephadex G 25 column, ECF was demonstrated in blisters of five patients with bullous pemphigoid, in three patients with systemic drug reactions and in one patient with blisters after contact with primula. ECF was not found in blisters of patients with epidermolysis bullosa and herpes gestationis or in DNCB-induced blisters. Fluid obtained from suction blisters was negative in normal controls and on unaffected skin of patients with atopic eczema, but contained ECF in eczematous areas. The demonstration of ECF in tissue fluid suggests that this factor plays a role in the local accumulation of eosinophils at sites of certain inflammatory reactions.

    Notes: Abstract Carotenoid accumulation in the cotyledons of the mustard seedling (Sinapis alba L.) is controlled by light. Besides the stimulatory function of phytochrome in carotenogenesis the experiments reveal the significance of chlorophyll accumulation for the accumulation of larger amounts of acrotenoids. A specific blue light effect was not found. The data suggest that light exerts its control over carotenoid biogenesis through two separate mechanisms: A phytochrome regulation of enzyme levels before a postulated pool of free carotenoids, and a regulation by chlorophyll draining the pool by complex-formation.
