AIM： To observe the effects of traditional antiinflammatory medicine Lonicerae FIos （LF） on rat reflux esophagitis （RE） induced by pylorus and forestomach ligation compared with the well-known proton antioxidant, α-tocopherol. METHODS： Rats were pretreated with three different dosages of LF （500, 250 and 125 mg/kg） orally, once a day for 14 d before pylorus and forestomach ligation. Nine hours after pylorus and forestomach ligation, changes to the stomach and esophagus lesion areas, gastric volumes, acid and pepsin outputs, antioxidant effects, esophageal lipid peroxidation, superoxide dismutase （SOD）, catalase （CAT）, malondialdehyde （MDA）, myeloperoxidase and glutathione （GSH） levels, and collagen contents （marker of flexibility） were observed on the esophageal and fundic histopathology. The results were compared with an α-tocopherol （once orally, 1 h before operation, 30 mg/kg） treated group in which the effects on RE were already ***： Pylorus and forestomach ligations caused marked increases of gross esophageal and gastric mucosa lesion areas, which corresponded with histopathological changes. In addition, increases of esophageal lipid peroxidation, decreases of SOD, CAT, and GSH-free radical scavengers, increases of collagen were observed. However, these pylorus and forestomach ligation induced RE were dose-dependently inhibited by treatment of 500, 250 and 125 mg/kg of LF extract, mediated by antioxidant effects. RE at 250 mg/kg showed similar effects α-tocopherol. CONCLUSION： The results suggest that antioxidant effects of LF could attenuate the severity of RE and prevent the esophageal mucosal damage, and validate its therapeutic use in esophageal reflux disease.

Chinese Journal of Integrative Medicine 2018年第11期24卷 844-852页

作者： Ji Hye Hwang Vinoth Kumar R Seok Yong Kang Hyo Won Jung Yong-Ki Park department of Acupuncture and Moxibustion Medicine College of Korean Medicine Gachon University department of herbology College of Korean Medicine Dongguk University

Objective： To investigate the effects of the flower buds extract of Tussilago farfara Linné（Farfarae Flos; FF） on focal cerebral ischemia through regulation of inflammatory responses in activated microglia. Methods： Brain ischemia was induced in Sprague-Dawley rats by a transient middle cerebral artery occlusion（t MCAO） for 90 min and reperfusion for 24 h. Twenty rats were randomly divided into 4 groups（n=5 per group）： normal, t MCAO-induced ischemic control, t MCAO plus FF extract 300 mg/kg-treated, and t MCAO plus MK-801 1 mg/kg-treated as reference drug. FF extract（300 mg/kg, p.o.） or MK-801（1 mg/kg, i.p.） was administered after reperfusion. Brain infarction was measured by 2,3,5,-triphenyltetrazolium chloride staining. Neuronal damage was observed by haematoxylin eosin, Nissl staining and immunohistochemistry using anti-neuronal nuclei（Neu N）, anti-glial fibril ary acidic protein（GFAP）, and antiCD11 b/c（OX42） antibodies in ischemic brain. The expressions of inducible nitric oxide synthase（i NOS）, tumor necrosis factor（TNF-α）, and hypoxia-inducible factor-1 a（HIF-1α） were determined by Western blot. BV2 microglial cel s were treated with FF extract or its main bioactive compound, tussilagone with or without lipopolysaccharide（LPS）. Nitric oxide（NO） production was measured in culture medium by Griess assay. The expressions of i NOS, COX-2 and pro-inflammatory cytokines mRNA were analyzed by reverse transcription-polymerase chain reaction. The expression of i NOS, and COX-2 proteins, the phosphorylation of ERK1/2, JNK, and p38 MAPK and the nuclear expression of NF-κB p65 in BV2 cells were determined by Western blot. Results： FF extract significantly decreased brain infarctions in ischemic rats（P〈0.01）. The neuronal death and the microglia/astrocytes activation in ischemic brains were inhibited by FF extract. FF extract also suppressed i NOS, TNF-α, and HIF-1α expression in ischemic brains. FF extract（0.2 and 0.5 mg/m L, P〈0.01） and tussilagone 20 and 50 μmol/L, P〈0

引用

World Journal of Gastroenterology 2017年第25期23卷 4644-4653页

作者： Mi-Rae Shin Hyo-Jin An Bu-Il Seo Seong-Soo Roh department of Pharmacology College of Korean Medicine Sangji University department of herbology College of Korean Medicine Daegu Haany University

To evaluate the anti-apoptotic effect of banhasasim-tang (BHSST) on chronic acid reflux esophagitis (CARE) using a rat model. METHODSA surgically-induced CARE model was established in Sprague-Dawley rats. The modeled rats were divided into a treatment group or untreated group, and given BHSST (1 g/kg body weight per day) or water, respectively, for 15 consecutive days (n = 7 each group). Changes in expression of proteins related to nicotinamide adenine dinucleotide phosphate (NADPH) oxidase and apoptosis were assessed by western blotting. Changes in esophageal pathology were analyzed by gross and histological examinations. RESULTSThe CARE exposure modeled rats showed increased levels of the NADPH oxidase subunit, NOX4 and p47phox in the esophagus. The BHSST treatment completely resolved these CARE-related increases. The CARE rats also showed markers of cytokine stress, including elevated levels of TNF-α and reactive oxygen species as well as of the consequent increase in JNK activation, and subsequent decrease in pro-survival gene expression, such as of Bcl-2. BHSST treatment resolved the CARE-related changes. BHSST also exerted an anti-apoptotic effect, as evidenced by altered expression of the apoptosis-related genes for bax, cytochrome c, and caspase 3. Finally, the BHSST treatment markedly ameliorated the CARE-related esophageal mucosal ulcerations. CONCLUSIONIn the rat model of CARE, BHSST can suppress development of esophageal mucosal ulceration via regulation of reactive oxygen species-dependent apoptosis.

A thorough analysis of the effect of surfactant/s on the solubility and pharmacokinetics of (S)-zaltoprofen

引用

Asian Journal of Pharmaceutical Sciences 2019年第4期14卷 435-444页

作者： Cuong Viet Pham Jong-Suep Baek Jong-Hun Park Sang-Hun Jung Jong-Seong Kang Cheong-Weon Cho College of Pharmacy and Institute of Drug Research and Development Chungnam National UniversityDaejeon 34134Republic of Korea department of herbology College of Korean MedicineDongguk UniversityGyeongju 38066Republic of Korea

Until now, there are no publications about the preformulation studies on(S)-zaltoprofen((S)-ZPF). Hence, we first investigated the solubility of(S)-ZPF, screened solubilizers and performed the pharmacokinetic study of(S)-ZPF in the presence of the solubilizers. The measurement of the solubility of(S)-ZPF in 26 different solvents was carried out, including d-alpha tocopheryl polyethylene glycol 1000 succinate(TPGS), 2-hydroxypropyl-β-cyclodextrin(HPCD), and mixtures of individual solvent. The plasma concentration of(S)-ZPF and the amount of(S)-ZPF retained in stomach were determined after oral(35.0 mg/kg) and intravenous(5.0 mg/kg) administration. The solubility of(S)-ZPF showed an increase of 484-fold in TPGS compared to its aqueous solubility. There was a significant increase of AUC 0-24 h for pure(S)-ZPF in the TPGS group(813.59 ± 64.17 μg h/ml) in comparison with AUC 0-24 h in the HPCD group(595.57 ± 71.76 μg h/ml) and water group(465.57 ± 90.89 μg h/ml). In addition, the T max of(S)-ZPF in the TPGS group was 2 h, much faster than that in the HPCD or water groups(5.50 or 5.67 h, respectively). This suggested that TPGS played a significant role in the increase of solubility and bioavailability of(S)-ZPF.

作者： Sang-Wan Seo Won-Seok Jung Tai-Guang Piao Seung-Heon Hong Ki-Jung Yun Rae-Kil Park Min-Kyo Shin Ho-Joon Song Sung-Joo Park department of herbology School of Oriental Medicine Wonkwang University Iksan Jeonbuk 570-749 South Korea Department of oriental Pharmacy College of Oriental Pharmacy Wonkwang University Iksan Jeonbuk 570-749 South Korea department of herbology School of Oriental Medicine Wonkwang University Iksan Jeonbuk 570-749 South Korea department of oriental Pharmacy College of Oriental Pharmacy Wonkwang University Iksan Jeonbuk 570-749 South Korea department of Pathology College of Medicine Wonkwng University Iksna Jeonbuk South Korea Vestibulocochlear Research Center & department of Microbiology College of Medicine Wonkwng University Iksna Jeonbuk South Korea

AIM： To investigate the effect of selective Cyclooxygenase-2 （COX-2） inhibitor 4-[5-（4-Chloro-phenyl）-3- （trifluoromethyl）- 1H-pyrazol- 1-yl] benzenesulfonamide （SC-236）, on the cholecystokinin （CCK）-octapeptideinduced acute pancreatitis （AP） in rats. METHODS： Wistar rat weighing 240 g to 260 g were divided into three groups. （1） Normal DMSO treated group, （2） SC-236 at 4 mg/kg treated group; SC-236 systemically administered via the intravenous （i.v.） catheter, followed by 75 μg/kg CCK octapeptide subcutaneously three times, after 1, 3 and 5 h. This whole procedure was repeated for 5 d. （3） Dimethyl sulfoxide （DMSO） treated group： an identical protocol was used in this group as in the SC-236 cohort （see 2. above）. Repeated CCK octapeptide treatment resulted in a typical experimentally induced pancreatitis in the Wistar rats. RESULTS： SC-236 improved the severity of CCK- octapeptide-induced AP as measured by laboratory criteria [the pancreatic weight/body weight （p.w/ b.w） ratio, the level of serum amylase and lipase]. The SC-236 treated group showed minimal histologic evidence of pancreatitis and a significant reduction in myeloperoxidase activity. SC-236 also increased heat shock protein （HSP）-60 and HSP72 compared with the DMSO-treated group in the CCK-octapeptide-induced AP and also reduced the pancreatic levels of COX-2. Furthermore, SC-236 reduced proinflammatory cytokine synthesis and inhibited NF-KB activation compared with the DMSO-treated group in the CCK-octapeptide-induced AP. CONCLUSION： Our results suggested that COX-2 plays pivotal role in the development of AP and COX-2 inhibitors may play a beneficial role in preventing AP.

引用

Chinese Journal of Integrative Medicine 2017年第10期23卷 755-762页

作者： Hyo Won Jung Kyung-Ho Kim Yong-Ki Park department of herbology College of Korean Medicine Dongguk University Gyeongju (740-814) Republic of Korea Korean Medicine Research and Development Center Dongguk University Gyeongju (740-814) Republic of Korea department of Acupuncture College of Korean Medicine Dongguk University Gyeongju (740-814) Republic of Korea

Objective： To investigate whether the dried root of Phellodendron amurense Ruprecht（Phellodendri cortex; PC） extract improves arthritic symptoms through anti-inflammatory and immune-modulatory effects in collagen-induced arthritis in mice. Methods： Rheumatoid arthritis（RA） was induced in male DBA/1 mice by immunization with type Ⅱ collagen（ColⅡ）. CIA mice were divided into 5 groups（n=10 per a group） with normal, CIA control, PC extract（50 mg/kg and 100 mg/kg）-treated, and meloxicam（50 mg/kg）-treated as the reference drug. The PC extract or meloxicam were administered orally in CIA mice once a day for 14 days after arthritis induction. Arthritic score, levels of anti-ColⅡ IgG2a antibody, prostaglandin E2（PGE2）, tumor necrosis factor（TNF）-α, and interleukin（IL）-17 in the sera of CIA mice were measured. Histopathological changes in the ankle joints of CIA mice were also analyzed by staining with hematoxylin and eosin（H and E）, safranin-O and immunohistochemistry using anti-TNF-α and anti-IL-17 antibodies. Results： The arthritic score was increased in CIA mice in a time-dependent manner, as were the serum levels of anti-ColⅡ IgG2a antibody, PGE2, TNF-α, and IL-17. However, the oral administration of PC extract at 50 and 100 mg/kg in CIA mice significantly decreased the arthritic scores, and the serum levels of anti-ColⅡ IgG2a, PGE2, TNF-α, and IL-17 compared with those in the CIA group（P〈0.05 or P〈0.01）. Furthermore, histopathological improvement of the joint architecture in CIA mice was observed after administration of PC extract. PC extract also significantly inhibited the expression of TNF-α and IL-17 in the joints of CIA mice by suppressing the expression of their m RNA and proteins. Conclusion： PC extract may improve the pathological progression of RA through the inhibition of joint destruction by synovial inflammation and immune-stimulation, therefore, it would be a potential anti-arthritic agent in RA.

AIM： To investigate the effect of Garden/a fasm/noides （GJ） on cerulein-induced acute pancreatitis （AP） in mice. METHODS： C57BL/6 mice weighing 18-20 g were divided into three groups. （1） Normal salinetreated group, （2） treatment with GJ at a dose of 0.1 g/kg, （3） treatment with GJ at a dose of 1 g/kg. GJ was administered orally （n = 6 per group） for 1 wk. Three hours later, the mice were given anintraperitoneal injection of cerulein （50 μg/kg）, a stable cholecystokinin （CCK） analogue, every hour for a total of 6h as described previously. The mice were sacrificed at 6 h after completion of cerulein injections. Blood samples were obtained to determine serum amylase, lipase and cytokine levels. The pancreas was rapidly removed for morphologic examination and scoring. A portion of pancreas was stored at -70℃ and prepared for the measurement of tissue myeloperoxidase （MPO） activity, an indicator of neutrophil sequestration, and for reverse-transcriptase PCR （RT-PCR） and real-time PCR measurements. RESULTS： Treatment with G.1 decreased significantly the severity of pancreatitis and pancreatitis-associated lung injury. Treatment with G.1 attenuated the severity of AP compared with saline-treated mice, as shown by reduction in pancreatic edema, neutrophil infiltration, serum amylase and lipase levels, serum cytokine levels, and mRNA expression of multiple inflammatory mediators. CONCLUSION： These results suggest that GJ attenuated the severity of AP as well as pancreatitisassociated lung injury.
