OBJECTIVE:To investigate the safety of hair essence containing 0.05%purified bee venom(HE-PBV)on the skin and eyes of New Zealand White ***:HE-PBV which contained 0.05%PBV,purified water,and glycerin,was used as the test *** skin-irritation test(SIT)and eye-irritation test(EIT)were conducted according to the Draize *** the SIT,HE-PBV(0.5 m L)dropped gauze was attached both intact and abraded skin for 24 *** other side of the skin was used as *** 24 and 72 h,the treatment site was observed and scored according to evaluation criteria for skin *** the EIT,the rabbits were divided into two groups:eye-washed(three rabbits)and non-eye-washed(six rabbits).HE-PBV(0.1 m L)was squirted into the right eye of *** left eye was untreated and used as a ***,20-30-s later,the eyes of rabbits in the eye-washed group were washed with^50 m L of physiologic(0.9%)salt ***,1,2,3,4 and 7 d after the start of the EIT,the eyes and behavior of the rabbits were *** degree of eye irritation elicited by HE-PBV was determined in three steps and then the criteria of the classification of eye-irritation ***:The SIT revealed erythema and edema at the site of HE-PBV *** 72 h,the body weight of rabbits was reduced slightly,but other symptoms(except erythema and edema)were not *** Primary Irritation Index score was0.6,and HE-PBV was deemed to be a slight *** EIT did not show mortality or body-weight fluctuation,but hyperemic conjunctiva and eyelid closure were noted after HE-PBV *** for these results,the score for the ophthalmic response on days 1,2,3,4 and 7 was 0,and HE-PBV was deemed to be a ***:These data suggest that HE-PBV did not elicit eye irritation,but was a slight irritant to the skin of rabbits;the latter slight would have been due to the excipients used in manufacture of the hair essence because PBV has been shown to be safe.

World Journal of Gastroenterology 2017年第32期23卷 5936-5944页

AIM To evaluate a novel grading system to predict lymph node metastasis(LNM) in patients with submucosal invasive colorectal carcinoma(SICRC).METHODS We analyzed the associations between LNM and various clinicopathological features in 252 patients with SICRC who had undergone radical surgery at the Seoul Saint Mary's hospital between 2000 and *** LNM was observed in 31 patients(12.3%). The depth and width of the submucosal invasion, lymphatic invasion, tumor budding, and the presence of poorly differentiated clusters(PDCs) were significantly associated with the incidence of LNM. Using multivariate analysis, the receiver operating characteristic curvewas calculated and the area under curve(AUC) was used to compare the ability of the different parameters to identify the risk of LNM. The most powerful clinicopathological parameter for predicting LNM was lymphatic invasion(difference AUC = 0.204), followed by the presence or absence of tumor budding(difference AUC = 0.190), presence of PDCs(difference AUC = 0.172) and tumor budding graded by the Ueno method(difference AUC = 0.128). CONCLUSION Our results indicate that the tumor budding and the depth multiplied by the width measurements of submucosal invasion can provide important information for patients with SICRC.

作者： So Jung Kim So Yun Park Sun-Mee Hong eun-Hye Kwon taek-Kyun Lee Gyeongbuk Institute for Marine Bio-Industry South Sea Environment Research Department Korea Institute of Ocean Science and Technology

Objective: To determine skin whitening and wrinkle improvement efficacy, glycoprotein fractions were extracted from liquid extracts of boiled sea cucumber and their effects on tyrosine and elastase inhibitory activities were assayed. Methods: Fractions above and below 50 k Da(>50 kD a and 50 kDa enhanced tyrosinase and elastase inhibitory activities by 50.84% and 28.78%, respectively. Correlations of the >50 kD a concentration with tyrosinase inhibitory(R^2=0.968) and elastase inhibitory(R2=0.983) efficacy were significant. Conclusions: >50 kD a glycoprotein fraction isolated from liquid extracts of boiled sea cucumber, which can serve as a functional cosmetic ingredient for whitening and wrinkle improvement of skin.

作者： eun Kyoung han Hae Kyoung Son Department of Nursing Eulji UniversitySeongnam13135South Korea

Dementia prevalence has soared due to population aging. In Mild Cognitive Impairment (MCI) as a pre-dementia stage, sleepdisturbances have raised much interest as a factor in a bidirectional relationship with cognitive decline. Thus, this studydeveloped the Sleep and Cognition Enhancement Multimodal Intervention (SCEMI) based on Lazarus’ multimodal approachand conducted a randomized controlled experiment to investigate the effects of the novel program on sleep and cognition inMCI elderly. The participants were 55 MCI elderly with sleep disturbances at two dementia care centers located in S-city,Gyeonggi-do, South Korea (n = 25 in the experimental group and n = 30 in the control group). The study period was fromNovember 01 to December 27, 2022. The experimental group received 8 sessions of SCEMI, 60 min per session once a *** control group received general education and guidance using a simplified booklet on the sleep and cognitive *** data collection, a self-reported questionnaire was used to investigate sleep quality, presleep arousal, cognitive function,stress, and depression. The results showed that, compared to the control group, the experimental group had significantlyimproved across all variables: sleep quality (U = 109.50, p hancesleep and cognition in community-dwelling MCI elderly with sleep disturbances.
