  • Objectives : The process through which mesenchymal cells condense and differentiate into chondrocytes to form new bone is known as endochondral bone formation. Chondrogenic differentiation and hypertrophy are essential steps in bone formation and are influenced by various factors. The stem bark and root bark of Eleutherococcus sessiliflorus (ES) have been widely used to treat growth retardation and arthritis in traditional Korean Medicine. In this study, we aimed to investigate the possible role of the stem bark of ES in the stimulation of chondrogenic differentiation in clonal murine chondrogenic ATDC5 cells. Methods : In ATDC5 cells treated with ES extract, cell viability and extracellular matrix production were determined using CCK-8 assay and Alcian blue staining, respectively, and alkaline phosphatase activity was measured. We also examined mRNA and protein expression levels of genes related to chondrogenic expression in ATDC5 cells using reverse transcription-polymerase chain reaction and western blot analyses. Results : ES extract increased the accumulation of Alcian blue-stained cartilage nodules and alkaline phosphatase activity in ATDC5 cells. It increased the mRNA expressions of chondrogenic markers including bone sialoprotein (BSP), cartilage collagens, Runt-related transcription factor-2 (RUNX-2), osteocalcin (OCN), β-catenin, and bone morphogenetic protein-2 (BMP-2), as well as the protein expressions of β-catenin, RUNX-2, BMP-2, and alkaline phosphatase (ALP). Conclusion : Taken together, these results suggest that ES extract exhibits a chondromodulating activity and therefore may be a possible agent for the treatment of bone growth disorders.

  • Physicochemical and antioxidant properties of the three different calorie types of HMR curry rice using fermented turmeric were analyzed in this study. The general tumeric added sample groups showed significantly higher carbohydrate content than the fermented turmeric sample group. In all sample groups, the ratio of protein, fat, and carbohydrate was found to be appropriate according to the nutritional composition ratio as one meal recommended by the Ministry of Health and Welfare. The brightness L value of the general turmeric-added sample group was measured to be significantly brighter than the fermented turmeric-added sample group. The fermented turmeric sample group showed a slightly lower pH value than the general sample group due to organic acids generated during fermentation. As a result of analyzing the radical scavenging activity of ABTS, LFTC, MFTC, and HFTC of the fermented turmeric group were 40.20, 40.46, and 36.16%, respectively, compared to those 32.41, 37.75, and 36.16% of LNTC, MNTC and FNTC of the general sample groups, respectively, consistently indicating that more free radicals were generated in the fermented sample group (p<0.01). Relatively unstable to heat and acid, DPPH scavenged radicals showed similar results to those of ABTS radical scavenging activity in terms of activity. Similar results were also shown in the measurement of total flavonoid and phenol content, which are known to have antioxidant antiviral and anticancer effects. Thus we could conclude that pilot products of the high quality varied calorie levels of HMR Bibimbap set with tumeric, which is helpful for antioxidant action have been developed to meet various customer needs.

  • Objectives : The purpose of this research was to examine the oriental medical term 'Yukjin(in chinese, liuchen)' i.e. 'good long-term storage of the six oriental medicinal herbs'. Yukjin has meant the six sorts of drugs which were well known for the older they stored, the better efficacious they were. This research was carried out to obtain more conclusive information about the time and the reason of the giving a naming Yukjin, and to arrange Yukjin's properties, toxicities and processes. Methods : We investigated the documents recorded in the medical classics of Yukjin and did the current issues and recent experimental researches of these medicines. Results : 1. The properties and flavors of Yukjin are pungent and bitter. When they were stored for a long time after gathering, their toxicities and stimuli were growing thinner, regarded as positive clinically with age and they should be used after processing. 2. The efficacies of Yukjin are not always in proportion to storage period. In case, they are stored too long, their efficacies and qualities may be deteriorated though volatility or pungent flavors are enfeebled. Conclusions : Consequently, toxicities and strong flavors of Yukjin can be reduced in various processes. So the traditional theory of long-term preservation is not necessarily retained. It may be desirable to store them for 1 to 3 years after harvest, to safen their toxicities and adverse reactions in the way of processing. If we use them properly according to oriental medicine method, it will be effective on treating and preventing the various diseases.

  • Objectives : The root bark of Morus alba L. (Mori Cortex Radidus; MCR) has been traditionally used to reduce heat from the lungs, soothe asthma, and edema and to promote urination. In this study, we investigated the effect of MCR ethanol extract on ovalbumin (OVA)-induced allergic asthma in mice. Methods : Mice were sensitized at day 0, 7 and 14 with 0.2% OVA and then airway challenged at day 21, 23, 25, 27 and 29 to induce allergic asthma. MCR extracts at doses of 50 and 100 mg/kg body weight (bw) were orally administered during OVA challenge once per a day. The levels of allergic mediators such as histamine, OVA-specific IgE, IFN-${\gamma}$ and IL-4 were measured in the sera of mice by ELISA. The histopathological change of lung tissues was observed with hematoxylin and eosin (H&E) staining. Results : MCR extract significantly decreased not only the serum levels of histamine, OVA-specific IgE, and IL-4 compared with those of OVA control group, but significantly increased the serum level of IFN-${\gamma}$. In H&E staining, MCR extract inhibited the infiltration of inflammatory cells and bronchiolar damage with epithelial thickening in lung tissues of OVA-induced asthma mice. Conclusions : These results indicate that MCR extract inhibits lung damage by asthma through regulating the allergic immune response, suggesting that MCR may be used as a useful agent for the treatment of allergic asthma.

  • Objectives : The root of Peucedanum japonicum Thunberg (Peucedani Japonici Radix; PJR) has been traditionally used as an herbal medicine for the treatment of anti-headache, anti-paralysis, anti-cancer, vascular protection, and blood pressure regulation. In this study, we investigated the anti-allergic effect of PJR water extract on ovalbumin (OVA)-induced allergic asthma in mice. Methods : Mice were sensitized at days 1, 8 and 15 with OVA and airway challenged at days 22, 24, 26, 28, and 30 to induced allergic asthma. PJR-W extract at doses of 100 and 300 mg/kg/body weight (bw) was orally administered during OVA challenge once per a day. The levels of allergic mediators such as immunoglobulin (Ig) E, and Th1/Th2 cytokines (IFN-${\gamma}$ and IL-4) were measured in the sera of mice by ELISA. The histological change of lung tissue was observed with hematoxylin and eosin (H&E) staining. Results : The administration of PJR-W extract significantly decreased the serum levels of IgE, IL-4, and IFN-${\gamma}$ compared with those of OVA control group. In H&E staining, PJR-E extract inhibited OVA-induced airway inflammation and the inflammatory cells infiltration in the peribronchial regions of the lung. Conclusions : These results indicate that PJR-W extract has an anti-inflammatory and anti-allergic effect on allergic response through the down-regulation of allergic mediators, suggesting that this herb may be used as a useful source for the treatment of allergic inflammatory diseases such as asthma.

  • Objectives : It has been known to be correlated between phlegm and dementia from the perspective of oriental medicine, but it is unexplored whether herbal medicines to treat phlegm have pharmacological actions on Alzheimer's disease (AD). The aim of this study was to evaluate and to compare effects of herbal medicines to treat phlegm against AD in vitro. Methods : We selected 11 herbal medicines which treat phlegm and obtained each extract by boiling in 10-fold distilled water for 2 h. And we performed the assay of acetylcholinesterase (AChE) inhibitory effects of 11 herbal extracts. Next, we evaluated neuroprotective effects of them against amyloid $beta_{25-35}$ ($A{\beta}_{25-35}$) plaque-induced toxicity in HT22 mouse hippocampal neuronal cells using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay. To investigate whether they show the anti-inflammatory effects against lipopolysaccharide (LPS), we also measured the levels of nitric oxide (NO) in BV2 microglia cells using griess reagent assay. Results : We found that Gamiyeongsin-hwan (GYH) and Cheonghunhwadam-tang (CHT) exhibited remarkable AChE inhibitory effects. In HT22 cells, Arisaematis Rhizoma, Trichosanthis Semen and Fritillariae Thunbergii Bulbus suppressed $A{\beta}_{25-35}$ plaque-induced neuronal cell death. In BV2 cells, Cheongung-hwan significantly inhibited the increase of NO contents induced by LPS and GYH and CHT showed a tendency to inhibit LPS-induced NO generation. Conclusions : These results suggest that several herbal medicines to treat phlegm showed the significant effects on AChE inhibition, neuroprotection against $A{\beta}_{25-35}$ plaque-induced toxicity, and inhibition of NO generation. Therefore, we demonstrate the possibility that herbal medicines with treating phlegm has effects against AD.

  • Background: Intravenous fluid therapy is one of the most common interventions in critically ill patients. Normal saline is frequently used, but there have been some concerns about hyperchloremia. Due to closer to plasma composition, crystalloids have been used as alternatives to normal saline. However, the optimal choice of resuscitative fluids remains controversial. Methods: MEDLINE, EMBASE, and CENTRAL were comprehensively searched until July 2021 to compare balanced crystalloids with normal saline in critically ill patients with the risk factors for multiple organ dysfunction syndromes (MODS).The primary endpoint was composite mortality. Secondary outcomes were acute kidney injury (AKI)/acute renal failure (ARF), and new receipt of renal replacement therapy (RRT). Results: A total of 1,240 studies were searched, and finally, 8 randomized controlled trials and 5 cohort studies were included. In the meta-analysis of composite mortality of 30,710 patients, balanced crystalloids compared to normal saline were significantly associated with reduced mortality (OR 0.80, 95% CI 0.68-0.95). In AKI/ARF, balanced crystalloids had a lower risk than normal saline (OR 0.91, 95% CI 0.84-0.99). There was no difference between balanced crystalloids and normal saline in risk of new receipt of RRT (OR 0.91, 95% CI 0.80-1.04). Conclusion: In fluid resuscitation for patients at high risk of MODS, the use of balanced crystalloids showed a significantly lower incidence of mortality compared to normal saline.

  • Background: Direct-acting antivirals are recommended for the treatment of chronic hepatitis C virus in Korea. However, evaluation of direct-acting antiviral regimens in a real-world setting is limited. The aims of this study were to investigate the effectiveness and safety of direct-acting antiviral treatment in Korean patients infected with chronic hepatitis C virus genotype 1b or 2 at a tertiary care hospital. Methods: This was a retrospective study conducted with patient data obtained between August 2015 and August 2019 at Jeonbuk National University Hospital. The primary effectiveness endpoint was sustained virological response 12 weeks post-treatment (SVR12) via intention-to-treat (ITT) and modified intention-to-treat (mITT) analyses. Results: Of the 270 patients, 47.0% were infected with genotype 1b and 53.0% with genotype 2. ITT analysis revealed that SVR12 was achieved in 78.9% of all patients, 77.2% in genotype 1b patients, and 80.4% in genotype 2 patients. Of the 21.1% of all patients who did not achieve SVR12, the majority of treatment failures were non-virologic failures (19.7%). mITT analysis revealed that SVR12 was achieved in 98.2% of all patients, 98.0% in genotype 1b patients, and 98.3% in genotype 2 patients. Almost half of all patients experienced one or more adverse events (43.3%), leading to 2.6% discontinuing scheduled treatment. The most common adverse event was anemia. Conclusions: Direct-acting antiviral-based treatment regimens showed high effectiveness and safety. Non-virological factors, such as premature treatment discontinuation due to adverse events or loss of follow-up, were the major disruptors in achieving SVR12.

  • Background: Topical corticosteroids (TCs) are available both as over-the-counter drugs and prescription medicines at pharmacies. Although they are generally safe drugs, inappropriate and excessive use could result in potential side effects. Thus, it is important to have appropriate knowledge regarding the use of TCs. We performed a cross-sectional survey to assess public knowledge and the potential misuse or overuse of TCs. Methods: A cross-sectional and nationwide online survey was conducted among participants who were aware of TCs. The survey items included sources of information, indications, potential side effects, and methods of application of TCs. A comparative analysis was conducted between those with (TC users) and without (TC non-users) an experience of using TCs. Results: Among 3,000 participants, 74.4% were TC users. The mass media was the most common information source of TCs, and only one-third of the surveyed people relied on pharmacists or doctors for information. Regarding indications and application methods, incorrect answer rate was high in some items, but respondents showed adequate knowledge. However, awareness of the safety of TCs was low. Overall, the TC users showed a higher knowledge of TCs than TC non-users. Conclusions: Public knowledge of the use of TCs appears to be appropriate. However, we found potential misuse or overuse of some items and a lack of awareness of the side effects concerning TCs. Thus, healthcare professionals' significant role is required.
