Effects of the Syzygium aromaticum L. extract on antioxidation and inhibition of matrix metalloproteinase in human dermal fibroblast

引用

Asian Pacific Journal of Tropical Biomedicine 2019年第2期9卷 53-59页

作者： Da Eun Kim yeon sil Hwang Bo Yoon Chang Dae Sung Kim Hyoung Kwon Cho Sung yeon Kim Institute of Pharmaceutical Research and Development College of PharmacyWonkwang University Hanpoong Pharm.CO. Ltd

Objective: To investigate cosmetic potential of Syzygium aromaticum L.(S. aromaticum L.) and to determine its antioxidant and anti-wrinkling effects. Methods: Using highperformance liquid chromatography, eugenol component was quantitated. The antioxidant activity of S. aromaticum L. was analyzed by 2,2-diphenyl-1-picrylhydrazyl radical scavenging and superoxide dismutase like activities. To determine cell viability, elastase and matrix metalloproteinase-1(MMP-1) activity, human dermal fibroblasts(HS68) were treated with S. aromaticum L. The inhibitory effect of S. aromaticum L. on tumor necrosis factor alpha induced MMPs expression in HS68 was analyzed by realtime-PCR. Results: The eugenol content was confirmed in S. aromaticum L. S. aromaticum L. was observed to have high 2,2-diphenyl-1-picrylhydrazyl radical scavenging activity and superoxide dismutase like activity. S. aromaticum L. had no cytotoxicity against the HS68 and dose-dependently increased elastase inhibition. Moreover, S. aromaticum L. significantly decreased MMP-1 content and inhibited gene levels of MMP-1, MMP-2, MMP-3 and MMP-9. Conclusions: The findings suggest that S. aromaticum L. has great potential as a cosmeceutical ingredient with antioxidant and antiwrinkling effects.

Effect of composite yogurt enriched with acacia fiber and Bifidobacterium lactis

World Journal of Gastroenterology 2012年第33期18卷 4563-4569页

AIM: To investigate whether composite yogurt with acacia dietary fiber and Bifidobacterium lactis (B. lactis) has additive effects in irritable bowel syndrome (IBS). METHODS: A total of 130 patients were randomly allocated to consume, twice daily for 8 wk, either the composite yogurt or the control product. The composite yogurt contained acacia dietary fiber and high-dose B. lactis together with two classic yogurt starter cultures. Patients were evaluated using the visual analogscale via a structured questionnaire administered at baseline and after treatment. RESULTS: Improvements in bowel habit satisfaction and overall IBS symptoms from baseline were significantly higher in the test group than in the control group (27.16 vs 15.51, P = 0.010, 64.2 ± 17.0 vs 50.4 ± 20.5, P < 0.001; respectively). In constipation-predominant IBS, improvement in overall IBS symptoms was significantly higher in the test group than in the control group (72.4 ± 18.4 vs 50.0 ± 21.8, P < 0.001). In patients with diarrhea-predominant IBS, improvement in bowel habit satisfaction from baseline was significantly higher in the test group than in the control group (32.90 vs 7.81, P = 0.006). CONCLUSION: Our data suggest that composite yogurt enriched with acacia fiber and B. lactis has greater therapeutic effects in patients with IBS than standard yogurt.

Krill oil ameliorates benign prostatic hyperplasia by regulating G-phase cell cycle arrest and altering signaling pathways and benign prostatic hyperplasia-associated markers

引用

Food Science and Human Wellness 2023年

Krill oil (KO) exhibits various biological activities， such as anti-inflammatory and antitumor effects. However， the inhibitory effects of benign prostatic hyperplasia (BPH) in vitro and in vivo have not yet been studied. This study investigated the anti-BPH effects of KO extracted by an enzymatic hydrolysis method. KO treatment inhibited the proliferation of WMPY-1 and BPH-1 cells by induction of G0/G1phase arrest through the modulation of positive and negative regulators in both prostate cell types. KO treatment stimulated phosphorylation of JNK and p38 signaling. In addition， KO changed the expression of BPH-related markers (5α-reductase， androgen receptor， FGF， Bcl-2， and Bax) and the activity of the proliferation-mediated NF-κB binding motif. KO-induced levels of proliferation-mediated molecules of prostate cells were attenuated in the presence of siRNA-specific p-38 (si-p38) and JNK (si-JNK). Furthermore， the administration of KO alleviated prostate size and weight and the cell layer thickness of prostate glands in a testosterone enanthate-induced BPH rat model. KO treatment altered the level of dihydrotestosterone in serum and the expression levels of BPH-related markers in prostate tissues. Finally， KO-mediated inhibition of prostatic growth was validated by histological analysis. These results suggest that KO has an inhibitory effect on BPH in prostate cells in vitro and in vivo. Thus， KO might be a potential prophylactic or therapeutic agent for patients with BPH.
