OBJECTIVE： This study aimed to evaluate whether Hwangryunhaedoktang （HHT）, a herbal compound, has an inhibitory effect on lipopolysaccharide （LPS）-induced inflammation in RAW264.7 macrophages. METHODS： The effects of HHT were evaluated by confirming nitric oxide （NO） production and expression of inducible NO synthase （iNOS） and mitogen-activated protein kinases （MAPKs） in LPS-stimulated RAW264.7 macrophages via the Griess assay, Western blotting, and real-time reverse transcription quantitative polymerase chain reaction. Western blot analyses and luciferase assays were used to evaluate whether HHT has an effect on the phosphorylation and translocation of nuclear factor-κB （NF-κB）. The secretion and expression of tumor necrosis factor-α （TNF-α） and interleukin-6 （IL-6） were determined via enzyme-linked immunosorbent assay and Western blot analyses. RESULTS： HHT suppressed LPS-induced NO production and expression of iNOS in a dose-dependent manner. Additionally, MAPKs activation was also attenuated via inhibition of phosphorylation of extracellular signal-regulated kinases 1/2, c-Jun N-terminal kinase and p38 which were related to inflammatory pathway. Furthermore, HHT also effectively attenuated NF-κB activation and its translocation to the nucleus, a process that is closely linked to inflammation. LPS normally induced the expression of inflammatory cytokines such as TNF-α and IL-6, but the secretion and expression of TNF-α and IL-6 were significantly attenuated by pretreating the cells with HHT. CONCLUSION： HHT suppressed LPS-induced NO production by blocking the activation of NF-κB and MAPK signaling pathways in RAW264.7 macrophages. Furthermore, HHT may have an anti-inflammatory effect by suppressing the LPS-induced secretion of TNF-α and IL-6. Therefore, the traditional herbal formula HHT might be a useful potential therapeutic agent for inflammation.

OBJECTIVE: To define the effects of Xanthoceras sorbifolia(EXS) on vascular inflammation and the mechanisms in endothelial ***: Vascular protective effects of an ethanol extract of seeds from EXS(1-50 μg/mL) against tumor necrosis factor-α(TNF-α)-induced vascularinflammation were examined in human umbilical vein endothelial cells(HUVECs).RESULTS: EXS significantly decreased TNF-α-induced expression of cell adhesion molecules, such as intracellular adhesion molecule-1, vascular cell adhesion molecule-1, and endothelial cell selectin,in a dose-dependent manner. Pre-treatment with EXS significantly inhibited translocation and transcriptional activity of nuclear factor-κB(NF-κB) increased by TNF-α. EXS also significantly inhibited formation of intracellular reactive oxygen species(ROS). Moreover, the vascular protective effects of EXS were linked to up-regulation of heme oxygenase-1(HO-1) and nuclear factor E2-related factor-2(Nrf-2) expression. EXS-induced HO-1 expression was significantly decreased in SnPP(HO-1 inhibitor)-and HO-1 siRNA-treated cells, whereas an increase was found in cobalt protoporphyrin IX(CoPP)(HO-1 inducer)-treated cells. In addition, pretreatment with EXS increased HO-1 and Nrf-2 expression under TNF-α stimulation with or without N-acetyl-L-cysteine. Furthermore, the inhibitory effects of EXS on TNF-α-induced vascular inflammation were partially reversed in SnPP-and of HO-1siRNA-treated cells but increased by ***: These results suggest that EXS may have important implications for prevention of vascular complications associated with vascular inflammation by inhibition of the NF-κB/ROS pathway and activation of the Nrf-2/HO-1 pathway.

Combination of Korean Red Ginseng Extract and Hydrogen-Rich Water Improves Spermatogenesis and Sperm Motility in Male Mice

引用

Chinese Journal of Integrative Medicine 2020年第5期26卷 361-369页

作者： Ja yoon Ku Min jung Park Hyun Jun Park Nam Cheol Park Bo Sun joo Department of Urology Pusan National University HospitalPusan National University School of MedicineBusan(49241)Republic of Korea Biomedical Research Institute Pusan National University HospitalBusan(49241)Republic of Korea The Korea Institute for Public Sperm Bank Busan(49241)Republic of Korea

Objective: To investigate the effect of hydrogen-rich Korean Red Ginseng(KRG) water(HRGW) mixture on the spermatogenesis and sperm motility of mice of different ages. Methods: Eighty young(3 month-old) and aged(12 month-old) male mice were randomly assigned to 4 groups(n=10 per group) including control group, hydrogen-rich water(HRW) group(10 m L/kg daily), KRG group(50 mg/kg daily) and HRGW group(10 m L/kg HRW and 50 mg/kg KRG daily) by an oral zoned needle for 4 weeks. Sperm count and motility were measured using sperm suspension released from cauda epididymis. Serum follicle stimulating hormone(FSH), luteinizing hormone(LH), testosterone, and reactive oxygen species(ROS) in serum have also been estimated. Tubular changes were examined through histological hematoxylin and eosin staining. Expression of antioxidation(PPx3, PPx4, GSTm5 and GPx4), spermatogenesis(inhibin-α, neptin-2 and CREM), antiaging(SIRT1 and SIRT2), and angiogenesis [visfatin and vascular endothelial growth factor(VEGF)] related genes were examined through realtime polymerase chain reaction. Results: HRW and KRG treatment stimulated spermatogenesis followed by increasing sperm production and sperm motility(P<0.05). These effects were strengthened synergistically by a HRGW mixture(P<0.05 or P<0.01). HRGW greatly increased the expressions of antioxidation, antiaging, spermatogenesis related genes and VEGF especially in aged mice(P<0.05). Serum testosterone and FSH levels also increased, while serum ROS level decreased(all P<0.05). Conclusion: HRGW increases sperm production and motility by enhancing antioxidation and stimulating spermatogenesis and sex hormone production, particularly in aged mice.

BACKGROUND A recent retrospective study confirmed that hepatic stiffness and splenic stiffness measured with magnetic resonance elastography(MRE) are strongly associated with the presence of esophageal varices. In addition, strong correlations have been reported between splenic stiffness values measured with MRE and hepatic venous pressure gradients in animal models. However, most studies have been conducted on adult populations, and previous pediatric MRE studies have only demonstrated the feasibility of MRE in pediatric populations, while the actual clinical application of spleen MRE has been *** To assess the utility of splenic stiffness measurements by MRE to predict gastroesophageal varices in *** We retrospectively reviewed abdominal MRE images taken on a 3 T system in pediatric patients. Patients who had undergone Kasai operations for biliary atresia were selected for the Kasai group, and patients with normal livers and spleens were selected for the control group. Two-dimensional spin-echo echoplanar MRE acquisition centered on the liver, with a pneumatic driver at 60 Hz and a low amplitude, was performed to obtain hepatic and splenic stiffness values. Laboratory results for aspartate aminotransferase to platelet ratio index(APRI) were evaluated within six months of MRE, and the normalized spleen size ratio was determined with the upper normal size limit. All Kasai group patients underwent gastroesophageal endoscopy during routine follow-up. The MannWhitney U test, Kendall's tau b correlation and diagnostic performance analysis using the area under the curve(AUC) were performed for statistical *** The median spleen MRE value was 5.5 kPa in the control group(n = 9, age 9-18 years, range 4.7-6.4 kPa) and 8.6 kPa in the Kasai group(n = 22, age 4-18 years,range 5.0-17.8 kPa).
