Case Study of a Patient with Trigger Finger after Conducting Pharmacopuncture according to the Progress.

Our study purpose was to report the clinical application of five different pharmacopunctures (Sweet BV, Scolopendrae Corpus, Chukyu, Cervi Parvum Cornu, and Hominis Placenta) for trigger finger. A patient was admitted to Ba-reun-mom S Korean Medicine Clinic and diagnosed with trigger finger. Because the effects of each pharmacopuncture have been confirmed in various acute to chronic cases, we treated a patient diagnosed with trigger finger using pharmacopunctures Sweet BV and Scolopendrae Corpus at the acute phase, Chukyu pharmacopuncture at the acute to chronic phase, and pharmacopunctures Cervi Parvum Cornu and Hominis Placenta at the chronic phase. This case was measured and assessed by Quinnell's classification of triggering and visual analogue scale (VAS) scores. After treatment, the patient's fifth finger pain and function were improved. The VAS score decreased from 5 to 0. The Quinnell's classification of triggering score decreased from 2 to 0. This case indicated that a patient with trigger finger could be treated by five pharmacopuncture treatments according to the treatment regimen and disease progress.

Salicornia herbacea Aqueous Extracts Regulate NLRP3 Inflammasome Activation in Macrophages and Trophoblasts.

Salicornia herbacea L. (Chenopodiaceae), an edible salt marsh plant with anti-inflammatory effects, was examined in macrophages and trophoblasts whether it modulates NLRP3 inflammasome activity. Pretreatment and delayed treatment of S. herbacea extract (SHE) in bone marrow-derived macrophages (BMDMs) reduced the activity of NLRP3 inflammasome induced by lipopolysaccharide (LPS) and adenosine triphosphate stimulation and downregulated interleukin (IL)-1ß production. SHE also inhibited pyroptotic cell death, the adaptor molecule apoptosis-associated speck-like protein containing a CARD (ASC), oligomerization, and speck by NLRP3 inflammasome activity in BMDM. Similarly, SHE decreased the mRNA expression of NLRP3, ASC, IL-1ß, and IL-6 in the LPS-stimulated human trophoblast cell line, Swan 71 cells. In addition, SHE inhibited the production of IL-6 and IL-1ß and decreased the expression of cyclooxygenase-2 and prostaglandin E2 in stimulated Swan 71 cells. Finally, 3,5-dicaffeoylquinic acid (3,5-DCQA), one of the components of S. herbacea, inhibited IL-1ß produced by NLRP3 inflammasome activity. In conclusion, SHE downregulated the activity of the NLRP3 inflammasome in macrophages and trophoblasts.

A Complex of Cirsium japonicum var. maackii (Maxim.) Matisum. and Thymus vulgaris L. Improves Menopausal Symptoms and Supports Healthy Aging in Women.

We evaluated the efficacy and safety of MS-10® for the treatment of menopausal symptoms. A double-blind randomized placebo-controlled clinical trial was performed in 71 premenopausal women for 4 and 12 weeks. A total of 12 individual menopausal symptom scores were assessed using the Kupperman index. MS-10 treatment effectively improved the symptoms by ∼48%. In addition, the quality of life of the women improved by 36% from four perspectives: vasomotor, psychosocial, physical, and sexual symptoms as evaluated using the menopause-specific quality of life (MenQoL) questionnaire. Our results show that MS-10 improves insulin-like growth factor-1 (IGF-1) and estrogen utilization through receptor activation, which are thought to have causative therapeutic effects on menopause and aging inhibition in women. Improvement of Enthotheline-1 (ET-1) in the blood after MS-10 intake led to an improvement in menopausal vascular symptoms. Improvements in bone formation and absorption markers such as osteocalcin, bone-specific alkaline phosphatase (BSALP), C-telopeptides of type I collagen (CTx), deoxypyridinoline (deoxyPYD), and N-telopeptides of type I collagen (NTx) in blood or urine indicate that MS-10 fundamentally improves bone health in women. By confirming the improvement of the psychological well-being index based on the improvement of stress hormone cortisol, MS-10 can solve causative psychological and physical stress-related symptoms. Moreover, various safety tests, such as those for female hormones, were confirmed. Therefore, it can be confirmed that MS-10 is a natural pharmaconutraceutical that causatively and safely improves health of women and aids in antiaging processes.

Optimizing Active Tumor Targeting Biocompatible Polymers for Efficient Systemic Delivery of Adenovirus.

Adenovirus (Ad) has risen to be a promising alternative to conventional cancer therapy. However, systemic delivery of Ad, which is necessary for the treatment of metastatic cancer, remains a major challenge within the field, owing to poor tumor tropism and nonspecific hepatic tropism of the virus. To address this limitation of Ad, we have synthesized two variants of folic acid (FA)-conjugated methoxy poly(ethylene glycol)-b-poly{N-[N-(2-aminoethyl)-2-aminoethyl]-L-glutamate (P5N2LG-FA and P5N5LG-FA) using 5 kDa poly(ethylene glycol) (PEG) with a different level of protonation (N2 < N5 in terms of charge), along with a P5N5LG control polymer without FA. Our findings demonstrate that P5N5LG, P5N2LG-FA, and P5N5LG-FA exert a lower level of cytotoxicity compared to 25 kDa polyethyleneimine. Furthermore, green fluorescent protein (GFP)-expressing Ad complexed with P5N2LG-FA and P5N5LG-FA (Ad/P5N2LG-FA and Ad/P5N5LG-FA, respectively) exerted superior transduction efficiency compared to naked Ad or Ad complexed with P5N5LG (Ad/P5N5LG) in folate receptor (FR)-overexpressing cancer cells (KB and MCF7). All three nanocomplexes (Ad/P5N5LG, Ad/P5N2LG-FA, and Ad/P5N5LG-FA) internalized into cancer cells through coxsackie adenovirus receptor-independent endocytic mechanism and the cell uptake was more efficient than naked Ad. Importantly, the cell uptake of the two FA functionalized nanocomplexes (Ad/P5N2LG-FA and Ad/P5N5LG-FA) was dependent on the complementary interaction of FA-FR. Systemically administered Ad/P5N5LG, Ad/P5N2LG-FA, and Ad/P5N5LG-FA showed exponentially higher retainment of the virus in blood circulation up to 24 h post-administration compared with naked Ad. Both tumor-targeted nanocomplexes (Ad/P5N2LG-FA and Ad/P5N5LG-FA) showed significantly higher intratumoral accumulation than naked Ad or Ad/P5N5LG via systemic administration. Both tumor-targeted nanocomplexes accumulated at a lower level in liver tissues compared to naked Ad. Notably, the nonspecific accumulation of Ad/P5N2LG-FA was significantly lower than Ad/P5N5LG-FA in several normal organs, while exhibiting a significantly higher intratumoral accumulation level, showing that careful optimization of polyplex surface charge is critical to successful tumor-targeted systemic delivery of Ad nanocomplexes.

High waist circumference rather than high body mass index may be a predictive risk factor for the longer disease duration of chronic spontaneous urticaria.

In a previous study, we found that higher waist circumference (WC) and higher body mass index (BMI) both increase the risk of chronic spontaneous urticaria (CSU). The aim of this study was to determine whether WC and BMI also increase the duration of CSU. We used multivariable Cox proportional hazards models to determine the hazard ratio (HR) for longer disease duration (longer than 3 years) according to WC and BMI. A total of 52,667 subjects were enrolled and their mean age was 54.5. After adjustments for other confounding variables the high WC/high BMI group had 1.062 times higher HR (95% CI, 1.028-1.098) than the normal WC/normal BMI group. Interestingly, the high WC/normal BMI group showed a significantly higher HR (1.053; 95% CI, 1.008-1.101) than the normal WC/normal BMI group, but not the normal WC/high BMI group (0.998; 95% CI, 0.951-1.046). Taken together, our results suggest that high WC rather than high BMI is a predictive risk factor for the longer disease duration of CSU.

Treatment of severe acute respiratory syndrome (SARS), Middle East respiratory syndrome (MERS), and coronavirus disease 2019 (COVID-19): a systematic review of in vitro, in vivo, and clinical trials.

Rationale: Coronavirus disease 2019 (COVID-19) has spread worldwide and poses a threat to humanity. However, no specific therapy has been established for this disease yet. We conducted a systematic review to highlight therapeutic agents that might be effective in treating COVID-19. Methods: We searched Medline, Medrxiv.org, and reference lists of relevant publications to identify articles of in vitro, in vivo, and clinical studies on treatments for severe acute respiratory syndrome (SARS), Middle East respiratory syndrome (MERS), and COVID-19 published in English until the last update on October 11, 2020. Results: We included 36 studies on SARS, 30 studies on MERS, and 10 meta-analyses on SARS and MERS in this study. Through 12,200 title and 830 full-text screenings for COVID-19, eight in vitro studies, 46 randomized controlled trials (RCTs) on 6,886 patients, and 29 meta-analyses were obtained and investigated. There was no therapeutic agent that consistently resulted in positive outcomes across SARS, MERS, and COVID-19. Remdesivir showed a therapeutic effect for COVID-19 in two RCTs involving the largest number of total participants (n = 1,461). Other therapies that showed an effect in at least two RCTs for COVID-19 were sofosbuvir/daclatasvir (n = 114), colchicine (n = 140), IFN-ß1b (n = 193), and convalescent plasma therapy (n = 126). Conclusions: This review provides information to help establish treatment and research directions for COVID-19 based on currently available evidence. Further RCTs are required.

Natural Bis-Benzylisoquinoline Alkaloids-Tetrandrine, Fangchinoline, and Cepharanthine, Inhibit Human Coronavirus OC43 Infection of MRC-5 Human Lung Cells.

Stephaniatetrandra and other related species of Menispermaceae are the major sources of the bis-benzylisoquinoline alkaloids tetrandrine (TET), fangchinoline (FAN), and cepharanthine (CEP). Although the pharmacological properties of these compounds include anticancer and anti-inflammatory activities, the antiviral effects of these compounds against human coronavirus (HCoV) remain unclear. Hence, the aims of the current study were to assess the antiviral activities of TET, FAN, and CEP and to elucidate the underlying mechanisms in HCoV-OC43-infected MRC-5 human lung cells. These compounds significantly inhibited virus-induced cell death at the early stage of virus infection. TET, FAN, and CEP treatment dramatically suppressed the replication of HCoV-OC43 as well as inhibited viral S and N protein expression. The virus-induced host response was reduced by compound treatment as compared with the vehicle control. Taken together, these findings demonstrate that TET, FAN, and CEP are potential natural antiviral agents for the prevention and treatment of HCoV-OC43 infection.

Coffee intake and decreased amyloid pathology in human brain.

Several epidemiological and preclinical studies supported the protective effect of coffee on Alzheimer's disease (AD). However, it is still unknown whether coffee is specifically related with reduced brain AD pathologies in human. Hence, this study aims to investigate relationships between coffee intake and in vivo AD pathologies, including cerebral beta-amyloid (Aß) deposition, the neurodegeneration of AD-signature regions, and cerebral white matter hyperintensities (WMH). A total of 411 non-demented older adults were included. Participants underwent comprehensive clinical assessment and multimodal neuroimaging including [11C] Pittsburgh compound B-positron emission tomography (PET), [18F] fluorodeoxyglucose PET, and magnetic resonance imaging scans. Lifetime and current coffee intake were categorized as follows: no coffee or <2 cups/day (reference category) and ≥2 cups/day (higher coffee intake). Lifetime coffee intake of ≥2 cups/day was significantly associated with a lower Aß positivity compared to coffee intake of <2 cups/day, even after controlling for potential confounders. In contrast, neither lifetime nor current coffee intake was not related to hypometabolism, atrophy of AD-signature region, and WMH volume. The findings suggest that higher lifetime coffee intake may contribute to lowering the risk of AD or related cognitive decline by reducing pathological cerebral amyloid deposition.

Effectiveness of group cognitive behavioral therapy with mindfulness in end-stage renal disease hemodialysis patients.

BACKGROUND: Many patients with end-stage renal disease (ESRD) undergoing hemodialysis (HD) experience depression. Depression influences patient quality of life (QOL), dialysis compliance, and medical comorbidity. We developed and applied a group cognitive behavioral therapy (CBT) program including mindfulness meditation for ESRD patients undergoing HD, and measured changes in QOL, mood, anxiety, perceived stress, and biochemical markers. METHODS: We conducted group CBT over a 12-week period with seven ESRD patients undergoing HD and suffering from depression. QOL, mood, anxiety, and perceived stress were measured at baseline and at weeks 8 and 12 using the World Health Organization Quality of Life scale, abbreviated version (WHOQOL-BREF), the Beck Depression Inventory II (BDI-II), the Hamilton Rating Scale for Depression (HAM-D), the Beck Anxiety Inventory (BAI), and the Perceived Stress Scale (PSS). Biochemical markers were measured at baseline and after 12 weeks. The Temperament and Character Inventory was performed to assess patient characteristics before starting group CBT. RESULTS: The seven patients showed significant improvement in QOL, mood, anxiety, and perceived stress after 12 weeks of group CBT. WHOQOL-BREF and the self-rating scales, BDI-II and BAI, showed continuous improvement across the 12-week period. HAM-D scores showed significant improvement by week 8; PSS showed significant improvement after week 8. Serum creatinine levels also improved significantly following the 12 week period. CONCLUSION: In this pilot study, a CBT program which included mindfulness meditation enhanced overall mental health and biochemical marker levels in ESRD patients undergoing HD.

Development of 68Ga-SCN-DOTA-Capsaicin as an Imaging Agent Targeting Apoptosis and Cell Cycle Arrest in Breast Cancer.

68Ga-labeled capsaicin using a DOTA (1,4,7,10-tetraazocyclododecane-N,N',N″,N'″-tetraacetic acid) derivative [68Ga-SCN-Benzyl(Bn)-DOTA-capsaicin] was studied for the diagnosis of breast cancers, such as MCF-7 and SK-BR-3. The standard compound, 69Ga-SCN-Bn-DOTA-capsaicin, was also prepared and characterized by spectroscopic analysis. The binding affinity of 68Ga-SCN-Bn-DOTA-capsaicin was evaluated by using breast cancer cell lines (MCF-7, SK-BR-3) and colon cancer cell (CT-26); the biodistribution was carried out by using MCF-7-bearing nude mice, after which the positron emission tomography (PET) images were obtained at different time intervals (15-120 minutes). 68Ga-SCN-Bn-DOTA-capsaicin showed a cellular uptake of 0.93% Injected Dose (ID) after 30 minutes of incubation, whereas 68Ga-SCN-Bn-DOTA showed a lower uptake of 0.25% ID. The tumor-to-blood ID/g% ratios increased and were found to be 0.49, 0.22, and 0.77 for 15, 30, and 60 minutes, respectively. The small-animal PET study showed that the uptake of 68Ga-SCN-Bn-DOTA-capsaicin was higher in the tumor regions even at 30 minutes after injection. These results suggest that 68Ga-SCN-Bn-DOTA-capsaicin is a potential targeting agent for PET imaging of MCF-7.

Intelligent pH indicator film composed of agar/potato starch and anthocyanin extracts from purple sweet potato.

A new colorimetric pH indicator film was developed using agar, potato starch, and natural dyes extracted from purple sweet potato, Ipomoea batatas. Both agar and potato starch are solid matrices used to immobilize natural dyes, anthocyanins. The ultraviolet-visible (UV-vis) spectrum of anthocyanin extract solutions and agar/potato starch films with anthocyanins showed color variations to different pH values (pH 2.0-10.0). Fourier transform infrared (FT-IR) and UV-vis region spectra showed compatibility between agar, starch, and anthocyanin extracts. Color variations of pH indicator films were measured by a colorimeter after immersion in different pH buffers. An application test was conducted for potential use as a meat spoilage sensor. The pH indicator films showed pH changes and spoilage point of pork samples, changing from red to green. Therefore, the developed pH indicator films could be used as a diagnostic tool for the detection of food spoilage.

Mental-Physical Comorbidity in Korean Adults: Results from a Nationwide General Population Survey in Korea.

OBJECTIVE: The aims of this study were to estimate the prevalence of mental-physical comorbidity and health-threatening risk factors in subjects with mental disorders, and the risks of mental disorders in those with physical diseases for the last 12 months in the general Korean population. METHODS: Korean Epidemiologic Catchment Area study replication (KECA-R) was conducted for 6,510 adults between August 2006 and April 2007. The Korean version of Composite International Diagnostic Interview 2.1 (K-CIDI) was used in the survey. Prevalence of mental and physical disorders, and risk factors for physical health were calculated, and their associations were evaluated with adjustment for age and sex. RESULTS: Subjects with any mental disorder showed significantly higher prevalence of chronic physical conditions (adjusted odds ratio, AOR=1.5 to 2.8, p<0.001) and medical risk factors including smoking, heavy drinking, overweight, and hypertension (AOR=1.5 to 4.0, p<0.001). Of those with chronic physical conditions, 21.6% had one or more comorbid mental disorder compared with 10.5% of the subjects without chronic physical disorders (AOR=2.6, p<0.001). Contrary to expectations, depressive disorders did not show significant association with hypertension and prevalence of obesity was not influenced by presence of mental disorders. Further studies should assess these findings. CONCLUSION: This is the first identification of significant mental-physical comorbidity in the general Korean population. Clinicians and health care officials should keep in mind of its potential adverse effects on treatment outcome and aggravated disease-related socioeconomic burden.

Disease awareness and management behavior of patients with atopic dermatitis: a questionnaire survey of 313 patients.

BACKGROUND: Patients with atopic dermatitis (AD) should be relatively well informed about the disorder to control their condition and prevent flare-ups. Thus far, there is no accurate information about the disease awareness levels and therapeutic behavior of AD patients. OBJECTIVE: To collect data on patients' knowledge about AD and their behavior in relation to seeking information about the disease and its treatment. METHODS: We performed a questionnaire survey on the disease awareness and self-management behavior of AD patients. A total of 313 patients and parents of patients with AD who had visited the The Catholic University of Korea, Catholic Medical Center between November 2011 and October 2012 were recruited. We compared the percentage of correct answers from all collected questionnaires according to the demographic and disease characteristics of the patients. RESULTS: Although dermatologists were the most frequent disease information sources and treatment providers for the AD patients, a significant proportion of participants obtained information from the Internet, which carries a huge amount of false medical information. A considerable number of participants perceived false online information as genuine, especially concerning complementary and alternative medicine treatments of AD, and the adverse effects of steroids. Some questions on AD knowledge had significantly different answers according to sex, marriage status, educational level, type of residence and living area, disease duration, disease severity, and treatment history with dermatologists. CONCLUSION: Dermatologists should pay more attention to correcting the common misunderstandings about AD to reduce unnecessary social/economic losses and improve treatment compliance.

Immunomodulatory effects of balneotherapy with hae-un-dae thermal water on imiquimod-induced psoriasis-like murine model.

BACKGROUND: Balneotherapy, although not a well-established dermatological treatment, is thought to have therapeutic properties for psoriasis and is used as an alternative treatment modality throughout the world. OBJECTIVE: To evaluate the mechanism underlying the therapeutic immunologic effects of thermomineral water. METHODS: A murine model of imiquimod-induced psoriasis-like skin inflammation was used for evaluating the therapeutic effects of balneotherapy with Hae-Un-Dae hot spring mineral water. The clinical improvements were evaluated by a dermatologist. Lesional cytokines, including interleukin (IL)-17A, IL-23, and IL-22, were quantitatively measured by real-time reverse transcriptase polymerase chain reaction. Serum levels of interferon-γ, IL-4, IL-5, and IL-17A were measured by enzyme-linked immunosorbent assay. T cell proportions in the spleen were evaluated by flow cytometry, and histopathological evaluation of the skin was also performed. RESULTS: The mineral water balneotherapy group showed faster improvement in skin erythema and scales than the distilled water bathing group. A substantial reduction was observed in the lesional mRNA levels of IL-17A and IL-23 in the mineral water group. Serum levels of IL-4 and IL-5 were significantly decreased in the mineral water group but not in the distilled water group. Normalized T cell proportions were observed after bathing. CONCLUSION: Balneotherapy showed immunomodulatory effects in a psoriasis-like murine model. Balneotherapy suppressed lesional IL-23 and IL-17A, which are important cytokines in the pathogenesis of psoriasis. These results suggest that balneotherapy can be used as an effective and safe treatment for psoriasis.

A split-face comparison of low-fluence Q-switched Nd: YAG laser plus 1550 nm fractional photothermolysis vs. Q-switched Nd: YAG monotherapy for facial melasma in Asian skin.

BACKGROUND: Melasma is a common pigmentary disorder which poses substantial therapeutic challenge. Combined therapy may be beneficial in Asians, where mixed type melasma is dominant. OBJECTIVE: We sought to assess the efficacy and safety of a 1064 nm Q-switched Nd: YAG (1064 QSNY) and a nonablative 1550 nm erbium-doped fractional photothermolysis (NFP) treatment in Asian melasma. METHODS: This was a split face study, in which 26 patients were treated with the 1064 QSNY (6 mm spot size, 1.2-1.4 J/cm(2) fluence) for 10 sessions at 2-week intervals to the entire face, and with the NFP (dynamic mode, pulse energy 6-8 mJ/microthermal zone (MTZ); total density 300 MTZs/cm(2)) for five sessions at 4-week intervals to the experimental side of the face. Efficacy variables were modified Melasma Area and Severity Index (mMASI), the physician's global assessment (PhGA), and patient's subjective global assessment (PGA). Safety was evaluated through the reporting of adverse events. RESULTS: The percentage of subjective improvement was virtually identical on both sides. The mMASI corroborated the patients' subjective estimate, both in terms of the degree of improvement and the lack of difference between the 1064 QSNY + NFP and the 1064 QSNY treated sides. No serious side effects were reported in either side. CONCLUSIONS: Our findings do not support the hypothesis of NFP providing a substantial benefit in treating the melasma when compared with the lone treatment of the 1064 QSNY.

A split-face comparison of ablative fractional lasers (CO(2) and Er:YAG) in Asian patients; postprocedure erythema, pain and patient's satisfaction.

Fractional photothermolysis has become popular in the recent years and is currently widely used for the treatment of scars and for photo-rejuvenation purposes. The fractional photothermolysis is to thermally alter a 'fraction' of the skin, leaving intervening areas of normal skin untouched, which rapidly repopulate the altered columns of tissue. Fractional photothermolysis is subdivided into non-ablative and ablative fractional resurfacing. Ablative fractional resurfacing uses fractional CO(2) or Er:YAG lasers to create deeper columns of thermal damage.Few studies have compared fractional CO(2) and Er:YAG lasers on scars and cutaneous photodamages by a split trial. In this pilot study, we have compared the effects, down time, postprocedure erythema, pain of CO(2) and Er:YAG fractional lasers using analysis of clinical photographs, dermoscopic findings and patient's rate of satisfaction.

Visible-to-near IR quantum dot-based hypermulticolor high-content screening of herbal medicines for the efficacy monitoring of hair growth promotion and hair loss inhibition.

There is a growing interest in alopecia prevention strategies, as the number of alopecia patients is increasing. We examine the efficacy of herbal medicine for hair growth promotion/hair loss inhibition in two cell lines via Western blot and high-content screening (HCS). Nine herbal extracts were obtained from three different herbal medicine mixtures using 3 different extraction methods. Five target proteins-IGF-1 (insulin-like growth factor-1), TGF-ß2 (transforming growth factor-ß2), VEGF (vascular endothelial growth factor), DKK-1 (Dickkopf-1), and Wnt5α-were observed for the assessment of hair growth promotion/hair loss inhibition efficacy. The efficacies of nine extracts were compared with minoxidil as control. Efficacy was defined as a rise in the expression levels of IGF-1, VEGF, and Wnt5α but a decrease in DKK-1 and TGF-ß2. Intracellular concurrent imaging of these proteins was successfully achieved using HCS, employing visible-to-near infrared probing based on quantum-antibody conjugates and hypermulticolor imaging.

Comparison of the effectiveness of nonablative fractional laser versus ablative fractional laser in thyroidectomy scar prevention: A pilot study.

A scar is a mark that remains after the healing of a wound or other morbid processes. In the past, treatment was mainly focused on severe scarring, such as the hypertrophic and burn scars. However, scars from relatively minor wounds can also be stressful. The site of an open thyroidectomy is the anterior neck, a prominently exposed part of the body, where postoperative scarring can cause patients distress. The cosmetic outcome of the scar after thyroidectomy is of particular importance to women, who constitute the majority of patients with thyroid disease. Active prevention is more likely to yield better cosmetic results and would require fewer treatment sessions and less expense than scar revision procedures. Many interventions have been proposed, but there is yet no universal consensus on optimal treatment. Recently, focus has been made on 'laser scar prevention', where various types of lasers have been used to improve the appearance of scars. The purpose of this study was to improve the appearance of scars, by laser intervention of the wound healing process. In this pilot study, we comparatively examined the effect of non-ablative 1550-nm fractional Er: glass laser and ablative 2940-nm fractional Er: YAG laser on fresh surgical scars of patients with Fitzpatrick skin type III-IV.

Effects of topically applied Korean red ginseng and its genuine constituents on atopic dermatitis-like skin lesions in NC/Nga mice.

Ginseng (the root of Panax ginseng C.A. Meyer, family Araliaceae) possesses various biological activities, including anti-inflammatory and anti-tumor actions. However, their topical effect on atopic dermatitis (AD) has not been studied yet. The aim of this study was to examine the therapeutic effects of topical Korean red ginseng saponin fraction (KRGS) and its genuine constituents on AD-like skin lesions in an AD mouse model. The therapeutic effect of topical KRGS and ginsenosides in 2-chloro-1,3,5-trinitrobenzene (TNCB)-treated NC/Nga mice was assessed by measuring the skin severity scores, ear thickness, histological changes of lesional skin including mast cell count, tissue tumor necrosis factor (TNF)-α, interleukin (IL)-4, and interferon (IFN)-γ mRNA expression, and total serum IgE. Topical administration of 0.1% KRGS, 0.1% Rh2 and 0.1% Rh2+0.1% Rg3 significantly reduced the clinical skin severity scores, ear thickness and mast cell infiltration in the TNCB-induced AD-like skin lesions. Topical application of KRGS and its constituents significantly reduced TNCB-induced increase in ear TNF-α and IL-4 mRNA expression, but not IFN-γ mRNA expression. There was little change of serum total IgE level by topical KRGS and its constituents. In this study, topical KRGS and ginsenosides Rh2 and Rg3 were found to exert an anti-inflammatory effect in vivo and proved to be beneficial in an animal model of AD. Our results suggest that KRGS and its ginsenosides Rh2 and Rg3 have potential as a topical agent for the treatment of AD.

BT-11 is effective for enhancing cognitive functions in the elderly humans.

Roots of Polygala tenuifolia Willdenow have been used in humans for centuries because of its sedative effects. We previously reported that BT-11, extracted from the roots of the plant, improved memory impairments in rats, enhanced memory in normal humans, and inhibited acetylcholinesterase activities in vitro. The present study was a randomized, double-blind, placebo-controlled comparison study to investigate whether BT-11 could enhance memory in the elderly humans. We used the Consortium to Establish a Registry for Alzheimer's Disease Assessment Packet (CERAD) and the Mini-Mental State Examination (MMSE). In the elderly, the total CERAD scores were much more significantly increased in the BT-11-treated group (n=28) than in the placebo-treated group (n=25). Especially, the mean scores of word list recognition, constructional recall and praxis, and modified Boston naming test were markedly improved in BT-11-treated group than in placebo-treated group. In conclusion, BT-11 could enhance some cognitive functions including memory in the elderly humans and therefore may be used as nutraceuticals that provide health benefits, including disease prevention and/or treatment.
