ABSTRACT

Skin ageing is influenced by both intrinsic and extrinsic factors, with excessive ultraviolet (UV) exposure being a significant contributor. Such exposure can lead to moisture loss, sagging, increased wrinkling, and decreased skin elasticity. Prolonged UV exposure negatively impacts the extracellular matrix by reducing collagen, hyaluronic acid, and aquaporin 3 (AQP-3) levels. Fermentation, which involves microorganisms, can produce and transform beneficial substances for human health. Natural product fermentation using lactic acid bacteria have demonstrated antioxidant, anti-inflammatory, antibacterial, whitening, and anti-wrinkle properties. Snowberry, traditionally used as an antiemetic, purgative, and anti-inflammatory agent, is now also used as an immune stimulant and for treating digestive disorders and colds. However, research on the skin benefits of Fermented Snowberry Extracts remains limited. Thus, we aimed to evaluate the skin benefits of snowberry by investigating its moisturising and anti-wrinkle effects, comparing extracts from different parts of the snowberry plant with those subjected to fermentation using Lactobacillus plantarum. Chlorophyll-free extracts were prepared from various parts of the snowberry plant, and ferments were created using Lactobacillus plantarum. The extracts and ferments were analysed using high-performance liquid chromatography (HPLC) to determine and compare their chemical compositions. Moisturising and anti-ageing tests were conducted to assess the efficacy of the extracts and ferments on the skin. The gallic acid content remained unchanged across all parts of the snowberry before and after fermentation. However, Fermented Snowberry Leaf Extracts exhibited a slight decrease in chlorogenic acid content but a significant increase in ferulic acid content. The Fermented Snowberry Fruit Extract demonstrated increased chlorogenic acid and a notable rise in ferulic acid compared to its non-fermented counterpart. Skin efficacy tests revealed that Fermented Snowberry Leaf and Fruit Extracts enhanced the expression of AQP-3, HAS-3, and COL1A1. These extracts exhibited distinct phenolic component profiles, indicating potential skin benefits such as improved moisture retention and protection against ageing. These findings suggest that Fermented Snowberry Extracts could be developed into effective skincare products, providing a natural alternative for enhancing skin hydration and reducing signs of ageing.

ABSTRACT

Herbal combinations of Rhei Radix et Rhizoma, Gardeniae Fructus, Cimicifugae Rhizoma, and Ginseng Radix have been used in traditional formulas to treat the symptoms of heat and dryness. This study investigated the therapeutic effects of a natural compound mixture (PSM) of these herbal combinations, containing emodin, genipin, chlorogenic acid, cimigenoside, and ginsenoside Rb1, for the treatment of psoriasis and its underlying molecular mechanisms. PSM was applied topically to the dorsal skin lesions of imiquimod- (IMQ-) induced C57BL/6 mice, and the expression of the proinflammatory mediators was investigated. The topical application of 1% PSM reduced psoriasis-like symptoms in IMQ-induced C57BL/6 mice significantly. PSM also attenuated the production of IFN-γ, IL-1ß, and IL-6 in skin lesions. Histological analysis showed that PSM had antipsoriatic effects by reducing the lesional epidermal thickness. Either M5 (IL-1α, IL-17A, IL-22, oncostatin M, and TNF-α, 10 ng/ml each) or IL-22- (100 ng/ml) stimulated HaCaT cells were used to examine the efficacy and underlying mechanism of PSM. In M5-stimulated HaCaT cells, PSM inhibited the production of C-X-C motif chemokine ligand (CXCL) 10 and C-C motif chemokine ligand (CCL) 20 effectively. Moreover, compared to the use of a single compound, it had synergistic inhibitory effects in CXCL8 production. PSM suppressed the phosphorylation of ERK1/2, p38, and STAT3 signaling pathways in M5-stimulated HaCaT cells. Furthermore, PSM reduced the proliferation rate and K16 and K17 expressions in IL-22-stimulated HaCaT cells by inhibiting the Akt/mTOR signaling pathway. These results suggest that PSM may have a therapeutic potential in the treatment of psoriasis lesions.

ABSTRACT

OBJECTIVES: The purpose of this study was to estimate the incidence of injuries and to identify their causes by classifying injuries according to various categories including age, sex, mechanism of injury, body parts injured, and place of injury. METHODS: This study used data from the Korea National Hospital Discharge In-depth Injury Survey (KNHDIS) from 2004 to 2016. The KNHDIS is conducted annually by the Korea Centers for Disease Control and Prevention, and its survey population includes all hospitalized patients discharged from medical institutions that have 100 or more beds, such as hospitals, general hospitals, and secondary community health centers. The number of injured cases is weighted and estimated using the mid-year estimated population of each year. RESULTS: The injury discharge rate steadily increased since 2004 (1,505 per 100,000 population in 2004, 2,007 per 100,000 population in 2016) and most injuries were unintentional (annual average of 94.7%). On average, during the 13-year study period, the injury rate for males was 1.5 times as high as for females. The 2 main causes of injury were consistently traffic accidents and falls. Notably, the rate of injuries resulting from falls rose by 1.7-fold from 463 to 792 per 100,000 people, and exceeded the rate of traffic accidents in 2016. CONCLUSIONS: The incidence of injuries steadily increased after the survey was first conducted, whereas mortality resulting from injuries mostly remained unchanged. This suggests that effective strategies and interventions should be reinforced to reduce unintentional injuries.

ABSTRACT

Acute exposure to ultraviolet (UV) radiation causes pro-inflammatory responses via diverse mechanisms including oxidative stress. Codium fragile is a green alga of Codiales family and has been reported to exhibit anti-edema, anti-allergic, anti-protozoal and anti-mycobacterial activities. In this study, we have investigated a novel anti-inflammatory potential of C. fragile using in vitro cell culture as well as in vivo animal models. In HaCaT cells, buthanol and ethylacetate fractions of 80% methanol C. fragile extract (CFB or CFE) and a single compound, clerosterol (CLS) isolated from CFE attenuated UVB (60 mJ/cm(2))-induced cytotoxicity and reduced expression of pro-inflammatory proteins including cyclooxygenase-2 (COX-2), inducible nitric oxide synthase (iNOS), and tumor necrosis factor-α (TNF- α). Moreover, CFB, CFE and CLS effectively suppressed UVB-induced production of pro-inflammatory mediators such as prostaglandin E2 (PGE2) and nitric oxide (NO). In another experiment, topical application of CFB, CFE or CLS prior to UVB irradiation (200 mJ/cm(2)) on BALB/c mice, inhibited the UVB-elevated protein levels of COX-2, iNOS, and TNF-α. Furthermore, CFB, CFE and CLS suppressed oxidative damages caused by UVB irradiation for example lipid peroxidation and/or protein carbonylation, which seemed to be mediated by up-regulation of antioxidant defense enzymes. These results suggest that C. fragile could be an effective therapeutic agent providing protection against UVB-induced inflammatory and oxidative skin damages.
