Alnus sibirica Fisch. ex Turcz.(AS) geographically distributes in Korea, Japan, Northeast China and Russia. The bark of Alnus species have been used as traditional medicine for the treatment of allergic skin diseases. The content evaluation of compounds which were isolated from the barks of A. sibirica processed enzymatic hydrolysis(EAS); hirsutanonol(1), 5-O-methylhirsutanonol(2), rubranol(3), hirsutenone(4) and muricarpone B(5) was conducted using HPLC. Consequently, in EAS, the content of glycoside was decreased considerably. But the aglycones(1, 3 and 4) were increased highly and 2, 5 were formed newly.

Eucommiae Cortex (EC), bark of Eucommia ulmoides, has been known as a traditional medicine to regulate hypertension and immune system. Because silk of gum in the EC blocks the release of active ingredients, EC generally has been utilized after processing with carbonization or salt-water to breakdown it. This study aimed to investigate the differences of non-processed EC and processed EC on antioxidant and anticancer properties. Antioxidant capacity was assessed by measuring the content of total polyphenols, reducing power, and ABTS radical scavenging effect. And anticancer effects were examined by evaluating the viability of pancreatic cancer cells and wound healing ability. The results demonstrated that processed EC contained more content of polyphenols and exhibited more potent reducing power and radical scavenging effect than non-processed EC. In addition, processed EC more efficiently inhibited proliferation and migration of pancreatic cancer cells. These results suggest that processing of medicinal plants can improve the biological properties such as antioxidant or anticancer activity, which may lead to the development of herbal medicine treatment technology.

The human genome has evolved as a consequence of evolutionary forces, such as natural selection. In this study, we investigated natural selection on the human genes by comparing the numbers of nonsynonymous (NS) and synonymous (S) mutations in individual genes. We initially collected all coding SNP data of all human genes from the public dbSNP. Among the human genes, we selected 3 different selection groups of genes: positively selected genes (NS/S${\geq}$3), negatively selected genes (NS/S${\leq}$1/3) and neutral selection genes (0.9

Shuangdan oral liquid (SDO) containing radix Salviae miltiorrhizae (Chinese name Danshen) and cortex moutan (Chinese name Mudanpi) is a traditional Chinese medicine using for treating vascular diseases. Danshensu (DSS) is a main effective monomer composition derived from radix Salviae miltiorrhizae and paeonol (Pae) from cortex moutan. Although the two herbs are widely used in traditional Chinese medicine, the pharmacological functions of their active compositions were not reported. Therefore, the research of DSS and Pae in mechanisms and pharmacodynamics interaction can provide scientific evidence to support clinical application. The diabetic nephropathy (DN) rats which were induced by streptozotocin (STZ) were treated with SDO, DSS, Pae, and DSS+Pae for eight weeks. The positive effects on DN animal models were investigated by detection of physiological and biochemical indexes and oxidative stress markers, within five treatments: SDO, DSS, Pae, DSS+Pae and insulin group. Compared with the model group, the DSS+Pae group improved the renal function, blood lipid metabolism and blood viscosity, increased the vitality of T-SOD or T-AOC and decreased the level of MDA or NO after the treatment. The study was successfully showed that the DSS+Pae group could delay the process of DN, especially in the renal injury part of histopathology changes. Our results suggest that the co-administration of DSS and Pae significantly may play a protective role in DN rats through decreasing the oxidative stress and improving the blood lipid metabolism mechanisms.

Objectives: The purpose of this study was to analyze the trend of natural product-based products for sleep improvement in Korean patents, to enhance the development and application of natural-products for sleep disorder in terms of Korean medicine. Methods: We collected patent data using the KIPRIS database and ScienceON database. Two authors independently screened patents that potentially met the criteria, and assessed full texts of screened patents for eligibility. Included patents were analyzed, quantitatively as well as qualitatively. Results: A total of 60 patents were selected 2008-July 2022. The number of patents have been on the rise since 2017, and reached 12 in 2018. Companies have registered the most patents, followed by the Industry-University Cooperation Foundation. Zizyphi semen (n=6), Lactuca sativa L. (n=5), Valeriana fauriei/officinalis (n=4), Poria cocos (n=4) were frequently used herbs among 60 patents. Twenty-one patents (35%) included medicinal herbs with sleep improving effects. Among 60 patents, alcohol extraction (70%) was mostly used, followed by water immersion (50%), and hot water extraction (48.3%). Conclusions: Analysis results showed that various Korean medicine herbs, are being used for natural-products for sleep disorder. The results will be helpful towards inventing new patents using Korean medicine, developing natural product extracts for sleep improvement, and extending the range of these products in clinical use.

Recent interest in the possible protective effects of dietary antioxidant compounds against human degenerative disease has prompted investigation of foods such as blueberries, which have a high antioxidant capacity. This study was performed to determine the antioxidative activity of methanol extract and solvent fractions from blueberry. Blueberry was extracted with methanol and then fractionated with n-hexane, EtOAc, BuOH and water to get active fractions. And their antioxidant capacities in each fraction were determined by using the DPPH and FRAP assay, and tyrosinase inhibitor. Ethyl acetate fraction of blueberry exhibited antioxidant capacity.

In the present study, the antinociceptive profiles of $Agrimonia$ $pilosa$ $Ledeb$ extract were examined in ICR mice. $Agrimonia$ $pilosa$ $Ledeb$ extract administered orally (200 mg/kg) showed an antinociceptive effect as measured by the tail-flick and hot-plate tests. In addition, $Agrimonia$ $pilosa$ $Ledeb$ extract attenuated the writhing numbers in the acetic acid-induced writhing test. Furthermore, the cumulative nociceptive response time for intrathecal (i.t.) injection of substance P (0.7 ${\mu}g$) was diminished by $Agrimonia$ $pilosa$ $Ledeb$ extract. Intraperitoneal (i.p.) pretreatment with yohimbine (${\alpha}_2$-adrenergic receptor antagonist) attenuated antinociceptive effect induced by $Agrimonia$ $pilosa$ $Ledeb$ extract in the writhing test. However, naloxone (opioid receptor antagonist) or methysergide (5-HT serotonergic receptor antagonist) did not affect antinociception induced by $Agrimonia$ $pilosa$ $Ledeb$ extract in the writhing test. Our results suggest that $Agrimonia$ $pilosa$ $Ledeb$ extract shows an antinociceptive property in various pain models. Furthermore, this antinociceptive effect of $Agrimonia$ $pilosa$ $Ledeb$ extract may be mediated by ${\alpha}_2$-adrenergic receptor, but not opioidergic and serotonergic receptors.

Here we have investigated how lactosylceramide (LacCer) modulates gene expression of adhesion molecules in TNF-${\alpha}$ and IFN ${\gamma}$ (CM)-stimulated astrocytes. We have observed that stimulation of astrocytes with CM increased the gene expression of ICAM-1 and VCAM-1. D-Threo-1-phenyl-2-decanoylamino-3-morpholino-1-propanol (PDMP) and N-butyldeoxynojirimycin (NBDNJ), inhibitors of glucosylceramide synthase (GLS) and LacCer synthase (galactosyltransferase, GalT-2), inhibited the gene expression of ICAM-1 and VCAM-1 and activation of their gene promoter induced by CM, which were reversed by exogenously supplied LacCer. Silencing of GalT-2 gene using its antisense oligonucleotides also attenuated CM-induced ICAM-1 and VCAM-1 expression, which were reversed by LacCer. PDMP treatment and silencing of GalT-2 gene significantly reduced CM-induced luciferase activities in NF-${\kappa}B$, AP-1, GAS, and STAT-3 luciferase vectors-transfected cells. In addition, LacCer reversed the inhibition of NF-${\kappa}B$ and STAT-1 luciferase activities by PDMP. Taken together, our results suggest that LacCer may play a crucial role in the expression of ICAM-1 and VCAM-1 via modulating transcription factors, such as NF-${\kappa}B$, AP-1, STAT-1, and STAT-3 in CM-stimulated astrocytes.
