Andrographolide sodium bisulfite (ASB), a water-soluble sulfonate of andrographolide has been shown to possess anti-inflammatory, antipyretic and analgesic activities. However, there is no report on the gastroprotective effect of ASB against indomethacin-induced gastric ulcer. Here we investigated the possible anti-ulcerogenic potential of ASB and the(More)
Pogostemonis Herba, known as "Guang-Huo-Xiang" in Chinese, has been widely used in the treatment of gastrointestinal dysfunction. Pogostone is one of the major constituents of Pogostemonis Herba. The aim was to scientifically evaluate the possible gastroprotective effect and the underlying mechanisms of pogostone against indomethacin-induced gastric ulcer(More)
Usnic acid is a dibenzofuran derivative found in several lichen species, which has been shown to possess several activities, including antiviral, antibiotic, antitumoral, antipyretic, analgesic, antioxidative and anti-inflammatory activities. However, there were few reports on the effects of usnic acid on LPS-induced acute lung injury (ALI). The aim of our(More)
Immunity and inflammation are well established factors in the pathogenesis of pulmonary arterial hypertension (PAH). We aimed to investigate whether dexamethasone (Dex), a potent immunosuppressant, could prevent the development of monocrotaline (MCT)-induced PAH in rats as compared with pyrrolidine dithiocarbamate (PDTC) and its effect on the immune(More)
Pogostemonis Herba is an important Chinese medicine widely used in the treatment of gastrointestinal dysfunction. Patchouli alcohol (PA), a tricyclic sesquiterpene, is the major active constituent of Pogostemonis Herba. This study aimed to investigate the possible anti-ulcerogenic potential of PA and the underlying mechanism against ethanol, indomethacin(More)
We isolated three new parvovirus variants in China. The isolate from a blue fox was related to feline parvovirus, but possessed a mutation of VP2 residue A300P. Isolates from a raccoon dog and a masked civet were antigenically similar to canine parvovirus-2a but had a substitution of VP2 residue G300S.
Interleukin-18(IL-18) plays a potential pathological role in rheumatoid arthritis (RA). The conclusions of the published reports on the relationship between single-nucleotide polymorphisms −607C/A (rs1946518) and −137G/C (rs187238) located in the IL-18 gene promoter and RA risk remain controversial. This meta-analysis was performed to evaluate the(More)
Pogostone, a major component of Pogostemon cablin, has been demonstrated to possess antibacterial, anti-fungal, immunosuppressive and anti-inflammatory properties. To investigate the potential therapeutic effect of pogostone on lipopolysaccharide (LPS)-induced acute lung injury (ALI), mice were pretreated with pogostone prior to LPS exposure. After LPS(More)
Streptococcal infection is believed to have an intimate relationship with psoriasis, although the pathogenic role of streptococcal DNA is not fully understood. To gain a clearer understanding of these dynamics, we investigated the effect of streptococcal DNA on lymphocyte proliferation and activation as well as cytokine secretion in psoriasis. Peripheral(More)
This study attempted to explore the effects of white pepper and its major component piperine on puerarin administered to rats. Pharmacokinetic parameters of puerarin in rats were determined by oral administration (400 mg/kg) or intravenous injection (40 mg/kg) of puerarin, pretreated with or without white pepper and piperine given orally. Compared to the(More)
