This study was aimed at investigating the effect of a pre-treatment on hair by using the end paper to which mask pack active ingredients were adsorbed as the pre-treatment before the permanent wave treatment. Among the mask packs with the highest preference in the ‘Hwahae’ application, the mask packs containing active ingredients such as collagen, Houttuynia cordata, and black soybean, which are good for hair protection, were purchased from the market and the active ingredients adsorbed onto the paper for treatment. For the experimental methods, hair thickness, tensile strength, hair cuticle observation using SEM and hair constituent elemental analysis using EDS were conducted. The results of hair thickness, tensile strength, hair cuticle observation and hair constituent elemental analysis showed that the experimental group treated with the active ingredient of black soybean had a hair protection effect. When the active ingredients used as a pre-treatment are developed as hair cosmetics, it is expected to be applied usefully in the field of industry, and thus it is hoped that studies on this will be actively conducted.
In mung beau (V/gna radiata), 1-aminocyclopropane-l-carboxylate synthase (ACS) is encoded by a multigene family that comprises at least seven members. Their expression is induced by hormones, developmental signals, inhibition of protein synthesis, or stress. We performed an RT.PCR assay to understand the differential accumulation of transcripts for ACC synthase homologs as a response to Li + in etiolated mung beau hypocotyls.Treating the seedlings with LiCI caused inductions of the ACS1, ACS4, ACS$, ACS6, and ACS7 genes. The induction level of ACS7 was particularly high. This effect on ACS7 expression was specific, lasting more than 8 h after the treatment. To understand the relationship of this Li + action with the phosphoinositide (PI) second messenger system, we examined the effect of Ca 2+ treatment on Li+-induction of the ACS7 gene. Because Ca z+ did not reverse the Li + effect, we suggest that regulation of the ACS7 gene by Li + in the mung beau may not involve the P! system.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
