Hypertrophic scarring is a common proliferative disorder of dermal fibroblasts characterized by collagen overproduction and excessive deposition of extracellular matrix (ECM). There is no consensus about the best therapeutics to produce complete and permanent improvement of scars with few side effects. To investigate the therapeutic effects of oleanolic(More)
Polydatin is one of main compounds in Polygonum cuspidatum, a plant with both medicinal and nutritional value. The possible hepatoprotective effects of polydatin on acute liver injury mice induced by carbon tetrachloride (CCl(4)) and the mechanisms involved were investigated. Intraperitoneal injection of CCl(4) (50 µl/kg) resulted in a significant increase(More)
The brown planthopper (BPH), Nilaparvata lugens, sugar transporter gene 6 (Nlst6) is a facilitative glucose/fructose transporter (often called a passive carrier) expressed in midgut that mediates sugar transport from the midgut lumen to hemolymph. The influence of down regulating expression of sugar transporter genes on insect growth, development, and(More)
A major challenge in ecology lies in understanding the coexistence of intraguild species, well documented at the organismal level, but not at the molecular level. This study focused on the effects of the antibiotic, jinggangmycin (JGM), a fungicide widely used in Asian rice agroecosystems, on reproduction of insects within the planthopper guild, including(More)
ETHNOPHARMACOLOGICAL RELEVANCE In the recent years, the international community has attached increasing importance to possible toxicity associated with Traditional Chinese Medicine (TCM). And hepatotoxicity is one of the major concerns, a fundamental pathological process induced by toxicant. This paper is in an attempt to identify the hepatotoxic components(More)
To investigate anti-arthritic effects of matrine isolated from the roots of S. flavescens on type II collagen-induced arthritis (CIA) in rats and to explore its related potential mechanisms, CIA rats were established and administered with matrine (20, 40 or 80 mg/kg/days, for 30 days). Subsequently, blood was collected to determine serum levels of TNF-α,(More)
The antibiotic jinggangmycin (JGM) is an agrochemical product widely used in China for controlling rice sheath blight, Rhizoctonia solani. Unexpectedly, it stimulates reproduction in the brown planthopper (BPH), Nilaparvata lugens (Stål). However, the underlying molecular mechanisms of the stimulation are unclear. The present investigation demonstrates that(More)
OBJECTIVE To observe the cytotoxic effects in vitro and antitumor effects in vivo of total alkaloid of Macleaya cordata. METHODS MTT assay was used to assess the proliferation of Hep3B and H22 cells in vitro treated with the alkloid, and the inhibitory effects of the alkaloid on H22 and S180 tumors were observed in mice with subcutaneous inoculation of(More)
ETHNOPHARMACOLOGICAL SIGNIFICANCE Icariin (I), ferulic acid (F) and timosaponin B II (T) derived respectively from the leaf of Epimedium brevicornu Maxim (EBM, Berberidaceae), rhizome of Anemarrhena asphodeloides Bunge (AAB, Liliaceae) and root of Angelica sinensis (Oliv.) Diels (ASD, Umbelliferae) are included in several traditional Chinese medicine (TCM)(More)
The fruits of Xanthium strumarium L. (Asteraceae) have been used extensively in China for treatment of various diseases such as allergic rhinitis (AR), tympanitis, urticaria and arthritis or ozena. This study was designed to systemically investigate the effects of the caffeoylxanthiazonoside (CXT) isolated from fruits of X. strumarium on AR in rodent(More)
