Son E, Lee YM, Kim SH, Kim DS. Photoprotective Effects of Processed Ginseng Leaf Administration against UVB-Induced Skin Damage in Hairless Mice. Molecules 2023; 28:6734. [PMID: 37764511 PMCID: PMC10534821 DOI: 10.3390/molecules28186734] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/02/2023] [Revised: 09/20/2023] [Accepted: 09/20/2023] [Indexed: 09/29/2023] Open
Abstract
Although ginseng leaves contain a larger amount of ginsenosides than the roots, studies on the protective effect of oral administration of ginseng leaves against photoaging are lacking. Processed ginseng leaves (PGL) prepared by acid reaction to increase effective ginsenoside content showed higher levels of Rg3 (29.35 mg/g) and Rk1 (35.16 mg/g) than ginseng leaves (Rg3 (2.14 mg/g) and Rk1 (ND)), and ginsenosides Rg3 and Rk1 were evaluated as active ingredients that protected human keratinocytes against UVB-induced cell damage by increasing cell proliferation and decreasing matrix metalloproteinase (MMP)-2 and 9 secretion. Herein, the effect of oral PGL administration (50, 100, or 200 mg/kg, daily) against photoaging in HR-1 hairless mice was assessed by measuring wrinkle depth, epidermal thickness, and trans-epidermal water loss for 16 weeks. The PGL treatment group showed reduced skin wrinkles, inhibited MMP-2 and MMP-9 expression, and decreased IL-6 and cyclooxygenase-2 levels. These data suggest that oral PGL administration inhibits photoaging by inhibiting the expression of MMPs, which degrade collagen, and inhibiting cytokines, which induce inflammatory responses. These results reveal that ginseng leaves processed by acid reaction may serve as potential functional materials with anti-photoaging activities.

Oral Supplementation with Z-Isomer-Rich Astaxanthin Inhibits Ultraviolet Light-Induced Skin Damage in Guinea Pigs. Mar Drugs 2022; 20:md20070414. [PMID: 35877706 PMCID: PMC9315510 DOI: 10.3390/md20070414] [Citation(s) in RCA: 9] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/01/2022] [Revised: 06/18/2022] [Accepted: 06/23/2022] [Indexed: 02/05/2023] Open
Abstract
The effect of oral supplementation with astaxanthin of different Z-isomer ratios on ultraviolet (UV) light-induced skin damage in guinea pigs was investigated. Astaxanthin with a high Z-isomer content was prepared from the all-E-isomer via thermal isomerization. Intact (all-E)-astaxanthin and the prepared Z-isomer-rich astaxanthin were suspended in soybean oil and fed to guinea pigs for three weeks. The UV-light irradiation was applied to the dorsal skin on the seventh day after the start of the test diet supplementation, and skin parameters, such as elasticity, transepidermal water loss (TEWL), and pigmentation (melanin and erythema values), were evaluated. The accumulation of astaxanthin in the dorsal skin was almost the same after consumption of the all-E-isomer-rich astaxanthin diet (E-AST-D; total Z-isomer ratio = 3.2%) and the Z-isomer-rich astaxanthin diet (Z-AST-D; total Z-isomer ratio = 84.4%); however, the total Z-isomer ratio of astaxanthin in the skin was higher in the case of the Z-AST-D supplementation. Both diets inhibited UV light-induced skin-damaging effects, such as the reduction in elasticity and the increase in TEWL level. Between E-AST-D and Z-AST-D, Z-AST-D showed better skin-protective ability against UV-light exposure than E-AST-D, which might be because of the greater UV-light-shielding ability of astaxanthin Z-isomers than the all-E-isomer. Furthermore, supplementation with Z-AST-D resulted in a greater reduction in skin pigmentation caused by astaxanthin accumulation compared to that of E-AST-D. This study indicates that dietary astaxanthin accumulates in the skin and appears to prevent UV light-induced skin damage, and the Z-isomers are more potent oral sunscreen agents than the all-E-isomer.

Abstract
Essential oils possess antiaging properties due to their antioxidant activity. This study aims to determine the antiaging activities of four main Indonesian essential oils and their irritation potential on the skin. The spot yeast and in vivo rat skin with UVB exposure methods were used to analyze the antiaging activity of essential oils on aging triggered by endogenous and exogenous factors, respectively. Meanwhile, patch tests and clinical evaluations were used for the skin irritation potential analysis. The antiaging activity results from the endogenous factor showed that the use of clove, patchouli, nutmeg, and citronella oils increased yeast viability at concentrations of 20, 40, 60, and 100 µg/mL, respectively. Furthermore, nutmeg, cloves, citronella, and patchouli oils decreased the wrinkle score on rat skin after UVB exposure (exogenous factor). The skin irritation potential results of patchouli, nutmeg, citronella, and clove oils were none (0), slightly (0.02), moderately (0.09), and very irritating (0.39), respectively.

Abstract
BACKGROUND The content of collagen and elastin occupies a large proportion of skin evaluation, and collagen peptide (CP) and elastin peptide (EP) are widely used drugs, which have anti-inflammatory effects. In addition, CP and EP can also be used as therapeutic agents for skin repair. However, previous studies have never thoroughly verified the effects of oral administration of CP and EP on skin repair. AIM To study the effects and mechanism of oral administration of CP and EP on skin aging induced by combinatorial treatment with D-galactose and ultraviolet radiation. RESULTS In animal experiments, the combined oral administration of CP and EP increased the contents of collagen and elastin in animal skin, accompanying with significantly upregulated expression of hyaluronic acid and hydroxyproline, as well as significantly reduced expression of MMP-3 and IL-1α. In addition, the combined therapy also significantly increased the expression of seven collagen and elastin synthesis-related factors including IGF-1, LOX, SMAD2, JNK, SP1, TβRII and TGF-β. CONCLUSION Oral administration of CP and EP can repair skin aging induced by the combined treatment with D-galactose and ultraviolet radiation and the effects of CP and EP appeared synergistic.

Abstract
Sanguisorba officinalis L. is widely used in China to treat various wounds, particularly burns. The present study was carried to evaluate the healing efficacy of a purified polysaccharide (SOP) from the roots of S. officinalis L. on burn wound models in mice. The results indicated that oral administration of SOP (50 and 200mg/kg) significantly stimulated wound contraction and reduced epithelialization time as compared to control group, which might be mediated by promoting collagen synthesis as evidenced by an increase of hydroxyproline content. Elevation of IL-1β and VEGF content was also observed in mice following SOP treatment, which in turn facilitate epithelization and angiogenesis. Besides, histopathological examination of the wound tissues in the SOP-treated animals showed collagen deposition and epidermal formation. It may be concluded that the enhancement of burn wound healing by SOP might be due to promotional collagen synthesis and angiogenesis during skin wound repair as a result of the stimulation of hydroxyproline, IL-1β and VEGF production. The excellent wound-healing activities of SOP provide a scientific rationale for the development of plant-based product in the management of wounds.

Abstract
Sanquisorba officinalis has been used internally for the treatment of intestinal infections and duodenal ulcers, as well as hemorrhoids, phlebitis and varicose veins and female disorders, and topically to heal wounds, burns, and ulcers. In our study, the antioxidant and antimicrobial activities, as well as quantitative analysis of polyphenols (phenolic acids, flavonoids and total polyphenols) in methanol and aqueous extracts from S. officinalis herbs are presented. A correlation between the antioxidant activity and composition of tested extracts indicates that flavonoids are the major compounds causing scavenging of free radicals. Higher content of flavonoids was found in the methanol extract, while the content of total phenolics was higher in the aqueous extract. Both extracts from S. officinalis herbs showed antioxidant activity and high antimicrobial activity in a wide spectrum of test strains.

Abstract
Polyphenolic-polysaccharide macromolecular, water-soluble glycoconjugates, isolated from the selected medicinal plants of Rosaceae/Asteraceae family: from leaves of Fragaria vesca L., Rubus plicatus Whe. et N. E., and from flowering parts of Sanguisorba officinalis L., and Erigeron canadensis L., were investigated for their ability to protect proteins and lipids of human plasma against γ-radiation-induced oxidative damage. Treatment of plasma with plant conjugates (6, 30, 150 μg/ml) prior exposure to 100 Gy radiation resulted in a significant inhibition of lipid peroxidation, evaluated by TBARS levels; conjugates isolated from E. canadensis and R. plicatus and a reference flavonoid quercetin showed similar high potential (approx. 70% inhibition, at 6 μg/ml). The conjugates prevented radiation-induced oxidation of protein thiols and significantly improved plasma total antioxidant capacity, estimated with Ellman's reagent and ABTS(.+) assay, respectively. The results demonstrate by the first time a significant radioprotective capability of the polyphenolic-polysaccharide conjugates isolated from E. canadensis, R. plicatus, S. officinalis and to the less extent from F. vesca. The abilities of these substances to inhibit radiation-induced lipid peroxidation and thiol oxidation in plasma seems to be mediated, but not limited to ROS scavenging activity.

Abstract
ZYM-201 is a methyl ester of triterpenoid glycoside from Sanguisorba officinalis which has been used for treatment of inflammatory and metabolic diseases. In this study, immunomodulatory effects of ZYM-201 on B cells were examined in vitro and in vivo. When splenocytes were activated with lipopolysaccharide (LPS), the major population which had shown an increase in cell numbers was B cells. However, when the B cells were treated with ZYM-201 after LPS activation, their cell numbers and the expression of major costimulatory molecules, CD80 and CD86, were decreased. Furthermore, the effect of LPS, which induces activation of NF-κB, was abolished by ZYM-201: LPS-stimulated B cells showed decrease of phosphorylation after treatment of ZYM-201. The same results were shown in vivo experiments. These results suggest that ZYM-201 may play a role in the modulation of inflammatory responses through inhibiting NF-κB activation and downregulating the expression of costimulatory molecules on B cells.

Abstract
Ultraviolet (UV) rays cause skin damage. Chronic exposure to UV irradiation causes decreased collagen synthesis, degenerative changes in collagen bundles, accumulation of elastotic material and increased epidermal thickness. Origanum hypericifolium, an endemic Turkish plant, belongs to Lamiaceae family. The main constituents of its oil are monoterpenes including cymene, carvacrol, thymol and γ-terpinene. The effects of undiluted O. hypericifolium oil on UVB irradiated skin of mice were investigated histochemically. Four groups of female BALB/c mice, whose dorsal hair was shaved, were allocated as follows: non-UVB irradiated (Group 1), UVB-irradiated (Group 2), O. hypericifolium oil treated (Group 3), and O. hypericifolium oil treated and UVB irradiated (Group 4). Sections of dorsal skin samples were stained with Mallory's phosphotungstic acid hematoxylin for collagen fibers and Taenzer-Unna orcein for elastic fibers. Sections also were stained with hematoxylin and eosin to measure epidermal thickness. We observed intense staining of collagen and homogeneous, scattered thin elastic fibers in Group 1; scattered and weakly stained collagen and curled, amorphous, accumulate elastic fibers in Group 2; and intense staining of collagen in Groups 3 and 4. Accumulation of elastic fibers in the dermis was unremarkable in Groups 3 and 4. In Groups 3 and 4, O. hypericifolium oil treatment thickened the epidermis. Epidermal thickness was greatest in Group 4. We suggest that O. hypericifolium oil may block UVB induced alterations of collagen and elastic fibers, and increase epidermal thickness.

Abstract
Oxidative stress and oxidative photodamage induced by UV radiation can cause serious skin damage that is characterized by wrinkling, roughness, laxity and pigmentation. The effects of a sea buckthorn (Hippophae rhamnoides L.) fruit blend (SFB) containing sea buckthorn fruit extract, blueberry extract and collagen on UV-induced skin aging were examined by treating hairless mice for 6 weeks with UV irradiation and SFB administered orally. The effects of SFB were measured in the skin of these mice by phenotypical and histological analysis and western blotting. According to wrinkle formation analysis, the oral intake of SFB induced a decrease in wrinkle formation in the damaged skin of UV-irradiated mice. The thickness of the epidermis and dermis in the vitamin extracts (Vit)- and SFB-treated group was lower than that in the vehicle-treated group, but the group treated with SFB50 was the most effective group. The mice treated with the Vit- or SFB solution maintained a normal moisture content through the inhibition of transdermal water loss (TEWL) and an increase in skin moisture content. Furthermore, the levels of matrix metalloproteinase (MMP) and collagen protein expression were assessed in five groups to examine the mechanisms underlying the effects of SFB oral intake. The application of SFB induced a decrease in MMP-1 and -9 expression to the levels observed in the vehicle-treated group, but MMP-9 expression showed a much larger decrease than MMP-1. Furthermore, the expression of collagen-1 in the skin corresponded to MMP expression except for the SFB30-treated group, whereas the superoxide dismutase (SOD) activity was increased dramatically in the SFB50-treated group. These results suggest that SFB has potential as a protective and therapeutic drug candidate against skin aging that functions by regulating the moisture content, MMP expression levels and SOD activity.

Abstract
CONTEXT The galls of Terminalia chebula Retz. (Combretaceae) frequently appear in many Thai Lanna medicinal plant recipes for promotion of longevity. OBJECTIVE The objective of this study was to evaluate the skin anti-aging of gel containing niosomes loaded with a semi-purified fraction containing gallic acid from T. chebula galls. METHOD The semi-purified fraction containing phenolic compounds including gallic acid isolated from T. chebula galls loaded in non-elastic or elastic niosomes, and its developed gel, were evaluated for rabbit skin irritation by the closed patch test and skin anti-aging in human volunteers by measuring skin elasticity and roughness. RESULTS Gel containing the fraction unloaded (SS) or loaded in non-elastic (SN) or elastic (SE) niosomes and gallic acid loaded in non-elastic (GN) or elastic (GE) niosomes showed no skin irritation, whereas the unloaded gallic acid (GS) gave the irritation in rabbit's skin by the closed patch test. The % parameter changes of skin elastic recovery and skin elastic extension when applied with SN and SE gels were +28.73 and +32.57; -21.25 and -22.63%, respectively. SN and SE gel also showed a significant decrease of the maximum and average roughness values with the parameter changes of -29.43 and -32.38; -39.47 and -35.28%, respectively. CONCLUSION The semi-purified fraction loaded in niosomes indicated not only higher chemical stability of gallic acid containing in the fraction, but also more in vivo anti-aging activities than the unloaded fraction when incorporated in gel.

Abstract
Elastic fibres are essential extracellular matrix components of the skin, contributing to its resilience and elasticity. In the course of skin ageing, elastin synthesis is reduced, and elastase activity is accelerated, resulting in skin sagging and reduced skin elasticity. Our studies show that non-denatured Glycine max (soybean) extracts induced elastin promoter activity, inhibited elastase activity and protected elastic fibres from degradation by exogenous elastases in vitro. Mouse and swine skins topically treated with soybean extracts showed enhanced elastic fibre network and increased desmosine content. Elastin expression was also augmented in human skin transplanted onto SCID mice in response to soy treatment. These data suggest that non-denatured soybean extracts may be used as skin care agents to reduce the signs of skin ageing.

Abstract
BACKGROUND Plants are the source of important products with nutritional and therapeutic value. Topical or oral administration of some plant extracts has been shown to reduce photodamage. Cacao bean and cola nut are popular edible plants that contain polyphenols and xanthine derivatives. These plant extracts possess protective effects against UV-induced erythema when taken orally, and an H(2)O(2)-scavenging effect. METHODS Plant extracts containing xanthine derivatives and three xanthine derivatives were topically applied to the dorsal skin of hairless mice, and the mice were exposed to a resemblance of solar ultraviolet irradiation at a dose of 13.0 J/cm(2) (UVA) for 15 weeks, five times a week on weekdays. After the final irradiation, histological, and analytical studies were performed. RESULTS Topical application of plant extracts (cacao beans, cola nuts) and caffeine, theobromine, and theophylline markedly prevented photodamage including wrinkle formation and histological alterations. A significant increase in total hydroxyproline content caused by UV irradiation was observed. In contrast, topical application of plant extracts and xanthine derivatives reduced total hydroxyproline and pepsin-resistant hydroxyproline content in comparison with that of the control (vehicle, UV-irradiation group). Moreover, naphthol AS-D chloroacetate esterase staining and diaminobenzidine staining suggested that leukocytes including neutrophils increased in the UV-exposed skin. In contrast, weak staining was observed in skin treated with xanthine derivatives. CONCLUSION Topical application of plant extracts and xanthine derivatives suppressed wrinkle formation, dermal connective alteration, and collagen accumulation. It is suggested that xanthine derivatives prevented neutrophil infiltration caused by UV-irradiation.

Abstract
BACKGROUND Previously, we have demonstrated that fibroblast-derived elastase plays an essential role in the increased three-dimensional tortuosity of elastic fibers, contributing to the loss of skin elasticity in UV-B-exposed skin. This decrease in skin elasticity is closely associated with the formation of wrinkles induced by UV exposure. OBJECTIVE To further clarify the role of elastase in the formation of wrinkles induced by UV exposure, we assessed the effects of an extract of Zingiber officinale (L.) Rose (which inhibits fibroblast-derived elastase) on the wrinkle formation induced by chronic UV-B irradiation. RESULTS Topical application of an extract of Zingiber officinale (L.) Rose to rat or hairless mouse skin significantly inhibited the wrinkle formation induced by chronic UV-B irradiation at a suberythemal dose, which was accompanied by a significant prevention of the decrease in skin elasticity in both types of animal skin. In the rat hind limb skin, consistent with the inhibition of reduced skin elasticity, wrinkle prevention occurred concomitantly with a significant decrease in the curling and three-dimensional tortuosity of dermal elastic fibers. CONCLUSION Our results indicate that herbal extracts with an ability to inhibit fibroblast-derived elastase may prove to be effective as anti-wrinkling agents, confirming the important role of elastase in UV-B-induced wrinkle formation.

Abstract
It has been reported that application of sunscreens prevents the photoaging of skin in animal models and in humans. We irradiated the dorsal skin of hairless mice with ultraviolet-A (UVA), and investigated the effects of sunscreens on skin elastase activity and on skin properties. Six-week-old female HR/ICR hairless mice were used in these experiments. After being treated with either a UVA sunscreen (also containing ultraviolet-B (UVB) sunscreen to eliminate any slight UVB in the UVA lamps; Protection Factor of UVA (PFA)=6, Sun Protection Factor (SPF)=20) or a vehicle, the dorsal skins of mice were irradiated with the UVA lamps at 22.3 J/cm(2)/d, 5 times a week. At the end of 15 weeks skin properties were evaluated and elastase activities were measured. In the vehicle control group, UVA irradiation increased the brightness and yellowing of the skin, decreased the water content of the stratum corneum, increased skin thickness, decreased skin elasticity, increased skin elastase activity, and decreased the ability of the skin to recover in a pinch test, as compared to an unirradiated group. All these differences were statistically significant. In the UVA sunscreen group, both the UVA induced skin damage and the increase in skin elastase activity were significantly inhibited, as compared to the vehicle group. However, as compared to the unirradiated group, skin elastase activity was significantly increased and immediate extensibility of skin (Ue) was significantly decreased, thereby indicating that the UVA sunscreen did not prevent photoaging to the same level as the unirradiated group. These results suggest the partial efficacy of the topical photoprotection from UVA by the sunscreen in inhibiting elastase activation, and also suggest the possibility of reducing photoaging.
