Definition: Given a passage with a context and an answer, construct a question on the basis of the information present in the passage. Construct the question in such a way that (i) it is unambiguous, (ii) it is answerable from the passage, (iii) its answer is unique (iv) it answer uses text phrases from the passage. Avoid creating questions that (i) can't be answered correctly without actually understanding the passage and (ii) uses the same words or phrases given in the passage.
Input: Context: Kochia scoparia (Chenopodiaceae) has been reported to have anti-nociceptive, anti-inflammatory, anti-allergic, and anti-pruritic actions. This study investigated the anti-inflammatory effects of externally applied Kochia scoparia water extract (KSW) in 2,4-dinitrochlorobenzene (DNCB)-induced contact dermatitis mouse model.', 'To develop atopic dermatitis-like skin lesions, 100L of 1% DNCB in acetone/olive oil (4:1) had been applied for three days on shaved dorsal skin. 1% KSW was topically applied to DNCB-induced mice. After KSW treatment, histological analysis was measured by hematoxylin eosin staining. The cytokine and pro-inflammatory expressions were examined using reverse transcription polymerase chain reaction and western blotting analysis.', 'Histological studies showed that hyperplasia of the epidermis and dermis in the KSW treated group was markedly decreased as compared with the DNCB group. The expression levels of pro-inflammatory cytokine such as IL-1, and TNF- mRNA were significantly reduced by topical application of KSW, whereas these cytokines were increased in DNCB-induced dorsal skin. In addition, NF-B expression was inhibited by KSW treatment in DNCB-induced mice. Similarly, KSW treatment significantly suppressed the expression of several MAP kinases, including ERK1/2, p38, and JNK compared to their expression in DNCB-induced mice.
Answer: These findings indicated that KSW ameliorates contact dermatitis via inhibition of the production of several inflammatory mediators. Therefore, external application of KSW may be used for the treatment of contact dermatitis as an alternative therapy.
Output:
Does topical application of Kochia scoparia inhibit the development of contact dermatitis in mice?
