Decrease of galectin-3 in keratinocytes: A potential diagnostic marker and a critical contributor to the pathogenesis of psoriasis.

Psoriasis-specific proteins dysregulated in keratinocytes and involved in the pathophysiological process of psoriasis remains elusive. We report here that epidermal galectin-3 expression is significantly downregulated in lesional skin, but not in non-lesional skin in psoriasis patients, nor in a group of diseases known as psoriasiform dermatitis clinically and histologically similar to psoriasis. The deficiency of epidermal galectin-3 is sufficient to promote development of psoriatic lesions, as evidenced by more severe skin inflammation in galectin-3 knockout (gal3) mice, compared to wild-type mice, after imiquimod treatment, and in skin from gal3 mice grafted onto wildtype mice.

[Influence of Cibotium barametz and its processed samples on haemorheology index in mice with adjuvant arthritis].

Objective: To discuss the influence of the rhizome of Cibotium barametz on the heamorheology index in mice with adjuvant arthritis and to compare the effect of raw medicinals with that of the processed ones.

Method: Mice was injected with Freund's complete adjuvant on the rihgt behind foot to make model of adjuvant arthritis (AA). Hydroxyacrbamide tablets were orally administrated by mice with AA to make model of AA due to deficiency in the kidney (DK-AA).
