The Effect of Improving Skin by Radiofrequency Microporation and Electroporation At-home Beauty Device with Glutathione Ampoule

This study aimed to evaluate the effects of improving facial skin, in healthy Korean women to objectively prove the efficacy of at-home beauty device equipped with RM (Radiofrequency Microporation) and EP (Electroporation) functions and cosmetics containing glutathione. RM and EP are methods that increase the permeation of cosmetics and active components into the skin by using microscopic channel formed when the skin barrier is damaged by electric stimulation. And glutathione is antioxidant component. For a study, a total of 42 study subjects (RM group 21 subjects and EP group 21 subjects) used a combination of at-home beauty device and a cosmetic containing glutathione on the face. Effectiveness assessments were conducted at 2 and 4 weeks, including the first visit. They all improved skin pores, pigmentation, and skin tone. The effectiveness assessment results showed that total pore area, feret's diameter were significantly (p<.05) improved after 2 weeks use in the test area compared to the control area, and pigmentation, skin tone was significantly (p<.05) improved after 4 weeks use in the test area compared to the control area. This result shows that the efficacy of glutathione as a cosmetic ingredient and the use of at-home beauty device combined with RM and EP functions are effective in improving skin. It is hoped that this study will help to develop skin beauty device models of various principles and expand the horizon of the skin beauty field.

Anti-Browning of Mushroom (<em>Agaricus bisporus</em>) Slices by Glutathione during Hot Air Drying

Browning of mushroom tends to occur during hot air drying due to Poly Phenol Oxidase (PPO), while glutathione is known for its ability to inhibit the activity of PPO and browning. In this study, the efficacy of glutathione in inhibiting browning on mushroom slices was estimated. Browning of mushroom slices treated with glutathione was monitored during hot air drying. PPO activity in mushroom was inhibited by 98.2 with 0.08% glutathione. Compared with the control, mushroom slices treated with glutathione showed no browning during hot air drying. These results indicate that application of glutathione is a promising method of Anti-browning of mushroom by glutathione during hot air drying.

Clinical observation of glutathione to reduce hepatic involvement of statin therapy patients with hepatitis B markers positive

Objective To observe the clinical efficacy of glutathione(GSH)to reduce hepatic involvement of statin therapy patients with hepatitis B markers positive.Methods 164 cases with hepatitis B markers positive were selected and divided into the treatment group(82 cases)and control group(82 cases).In a statin therapy with primary disease,at the same time,the control group using based protect liver therapy(both inosine,vitamin C),the treatment group using reduced glutathione intravenous drip(1.2g,one/d).After 12 weeks,the liver function was examined.Results Patients taking statins ALT,TB and DB levels obviously higher than before,had a statistically significant difference(t=2.66,1.98,2.13,P＜0.05),the differences of observation index level in treatment group before and after treatment had no statistical difference(P＞0.05),12 patients(14.6％)ALT level in treatment group were more than normal,0 case more than normal limit 3 times,control group respectively for 23 cases(28.1％),3 cases(3.7％),two groups had statistically significant difference(x2=4.672,5.304,all P＜0.05).Conclusion GSH can obviously reduce hepatic involvement of statin therapy patients with hepatitis B markers positive. Key words: Hepatic involvement; Hepatitis B,chronic; Glutathione; Statin

Efficacy of Glutathione in Ameliorating Sulfur Mustard Analog-Induced Toxicity in Cultured Skin Epidermal Cells and in SKH-1 Mouse Skin In Vivo

Exposure to chemical warfare agent sulfur mustard (HD) is reported to cause GSH depletion, which plays an important role in HD-linked oxidative stress and skin injury. Using the HD analog 2-chloroethyl ethyl sulfide (CEES), we evaluated the role of GSH and its efficacy in ameliorating CEES-caused skin injury. Using mouse JB6 and human HaCaT epidermal keratinocytes, we observed both protective and therapeutic effects of exogenous GSH (1 or 10 mM) in attenuating a CEES-caused decrease in cell viability and DNA synthesis, as well as S and G(2)M phase arrest in cell cycle progression. However, the protective effect of GSH was stronger than its ability to reverse CEES-induced cytotoxic effect. The observed effect of GSH could be associated with an increase in intracellular GSH levels after its treatment before or after CEES exposure, which strongly depleted cellular GSH levels. N-Acetyl cysteine, a GSH precursor, also showed both protective and therapeutic effects against CEES-caused cytotoxicity. Buthionine sulfoximine, which reduces cellular GSH levels, caused an increased CEES cytotoxicity in both JB6 and HaCaT cells. In further studies translating GSH effects in cell culture, pretreatment of mice with 300 mg/kg GSH via oral gavage 1 h before topical application of CEES resulted in significant protection against CEES-caused increase in skin bifold and epidermal thickness, apoptotic cell death, and myeloperoxidase activity, which could be associated with increased skin GSH levels. Together, these results highlight GSH efficacy in ameliorating CEES-caused skin injury and further support the need for effective antioxidant countermeasures against skin injury by HD exposure.

Glutathione deficiency intensifies ischaemia-reperfusion induced cardiac dysfunction and oxidative stress.

The efficacy of glutathione (GSH) in protecting ischaemia-reperfusion (I-R) induced cardiac dysfunction and myocardial oxidative stress was studied in open-chest, stunned rat heart model. Female Sprague-Dawley rats were randomly divided into three experimental groups: (1) GSH-depletion, by injection of buthionine sulphoxamine (BSO, 4 mmol kg(-1), i.p.) 24 h prior to I-R, (2) BSO injection (4 mmol kg(-1), i.p.) in conjunction with acivicin (AT125, 0.05 mmol kg(-1), i.v.) infusion 1 h prior to I-R, and (3) control (C), receiving saline treatment. Each group was further divided into I-R, with surgical occlusion of the main left coronary artery (LCA) for 30 min followed by 20 min reperfusion, and sham. Myocardial GSH content and GSH : glutathione disulphide (GSSG) ratio were decreased by approximately 50% (P < 0.01) in both BSO and BSO + AT125 vs. C. Ischaemia-reperfusion suppressed GSH in both left and right ventricles of C (P < 0.01) and left ventricles of BSO and BSO + AT125 (P < 0.05). Contractility (+dP/dt and -dP/dt) in C heart decreased 55% (P < 0.01) after I and recovered 90% after I-R, whereas +/-dP/dt in BSO decreased 57% (P < 0.01) with ischaemia and recovered 76 and 84% (P < 0.05), respectively, after I-R. For BSO + AT125, +/-dP/dt were 64 and 76% (P < 0.01) lower after ischaemia, and recovered only 67 and 61% (P < 0.01) after I-R. Left ventricular systolic pressure in C, BSO and BSO + AT125 reached 95 (P > 0.05) 87 and 82% (P < 0.05) of their respective sham values after I-R. Rate-pressure double product was 11% (P > 0.05) and 25% (P < 0.05) lower in BSO and BSO + AT125, compared with Saline, respectively. BSO and BSO + AT125 rats demonstrated significantly lower liver GSH and heart Mn superoxide dismutase activity than C rats after I-R. These data indicate that GSH depletion by inhibition of its synthesis and transport can exacerbate cardiac dysfunction inflicted by in vivo I-R. Part of the aetiology may involve impaired myocardial antioxidant defenses and whole-body GSH homeostasis.
