Regular and prophylactic use of topical corticosteroids is a well tolerated and effective treatment for allergic rhinitis. The symptomatology of allergic rhinitis is considered to be the result of the accumulation and activation of infiltrating inflammatory cells, releasing mediators, and cytokines. Corticosteroids can suppress many stages of the allergic inflammatory process. This may explain their potent effect on allergic symptomatology. The reduction in cell numbers and probably also cytokines by local corticosteroid therapy differs from cell to cell. Some cells, such as antigen presenting (Langerhans) cells and eosinophils, are highly sensitive to corticosteroid treatment. Others, like T cells, are only significantly reduced in exaggerated situations, for instance after provocation with a high allergen dose or after treatment with a high dose of corticosteroids. Some cells, like macrophages, are not influenced at all.

This article deals with fast pyrolysis of brown algae, such as Bifurcaria Bifurcata at the range of temperature 300–800 °C in a stainless steel tubular reactor. After a literature review on algae and its importance in renewable sector, a case study was done on pyrolysis of brown algae especially, Bifurcaria Bifurcata. The aim was to experimentally investigate how the temperature, the particle size, the nitrogen flow rate (N2) and the heating rate affect bio-oil, bio-char and gaseous products. These parameters were varied in the ranges of 5–50 °C/min, below 0.2–1 mm and 20–200 mL. min–1, respectively. The maximum bio-oil yield of 41.3wt% was obtained at a pyrolysis temperature of 600 °C, particle size between 0.2–0.5 mm, nitrogen flow rate (N2) of 100 mL. min–1 and heating rate of 5 °C/min. Liquid product obtained under the most suitable and optimal condition was characterized by elemental analysis, 1H-NMR, FT-IR and GC-MS. The analysis of bio-oil showed that bio-oil from Bifurcaria Bifurcata could be a potential source of renewable fuel production and value added chemicals.
