Data on the potent fibrinolytic effects of the earthworm and the lugworm.

There is technology available for anti-thrombus with earthworms, but the procedure is complex and extracts protein with inferior purity. In order to develop a simplified process with a stronger purity of protease, we investigated the earthworm and lugworm. We purified water extracts cut off at 10 kDa of molecular weight using ultrafiltration because proteins are large biomolecules, or macromolecules, consisting of one or more long chains of amino acid residues.

Anti-inflammatory effects of the combined extracts of and and .

This study investigated the anti-inflammatory effects of mixed extracts of (AJ) and (AC) (ratios of 1:2, 1:3, 1:5, 2:1, 3:1 and 5:1) on RAW264.7 macrophages and evaluated the anti-inflammatory effects of the mixed extracts of AJ and AC by measuring IL-1, IL-6, and TNF using the ELISA kit assay. In particular, the formation of nitric oxide (NO) was found to decrease in the group treated with the combined extracts of AJ and AC at all ratios.

Angiotensin I-converting enzyme inhibitor derived from cross-linked oyster protein.

Following cross-linking by microbial transglutaminase, modified oyster proteins were hydrolyzed to improve inhibitory activity against angiotensin-converting enzyme (ACE) inhibitory activity with the use of a single protease, or a combination of six proteases. The oyster hydrolysate with the lowest 50% ACE inhibitory concentration (IC50) of 0.40 mg/mL was obtained by two-step hydrolysis of the cross-linked oyster protein using Protamex and Neutrase.

Effects of acupuncture on the tissue distribution of Paclitaxel in lung carcinoma mice.

Objective: To study whether acupuncture affects the tissue distribution of Paclitaxel in mouse lung carcinoma.

Methods: Totally 90 mice were divided into Paclitaxel group, Paclitaxel + Feishu (BL13) group, and Paclitaxel + Lingtai (DU10) group. Each group was consisted of 30 mice.

Different Surface Electromyography of Propagated Sensation along Meridians Produced by Acupuncturing Quchi Acupoint (LI11) or Control Points.

This study investigated the propagated sensation along meridians (PSM) produced respectively by acupuncture at a specific acupoint of right-side Quchi (LI11), a nonacupoint on meridian (control meridian point), and neither meridian nor acupoint (control point). All the stimulated points were on the right brachioradialis along the large intestine meridian of hand Yangming. Surface electromyography (sEMG) was used to reflect the activity of the brachioradialis along the large intestine meridian of hand Yangming.

Expression and clinical significance of extracellular matrix metalloproteinase inducer, EMMPRIN/CD147, in human osteosarcoma.

Osteosarcoma is the most common primary malignant bone tumor in children and adolescents. Recent studies have shown that extracellular matrix metalloproteinase inducer (EMMPRIN/CD147) promotes adhesion, invasion and metastasis of malignant tumor cells. The aim of this study was to investigate the impact of EMMPRIN/CD147 expression on prognosis and its correlation with clinicopathological characteristics in patients with osteosarcoma.

Effects of acupuncture at Taixi acupoint (KI3) on kidney proteome.

This research explored and identified the protein composition of rat kidneys after acupuncture at the Taixi acupoint (KI3). Twelve adult male Wistar rats were randomly divided into a control group (n = 6) and an acupuncture group (n = 6). Rats in the acupuncture group received electroacupuncture on the bilateral KI3 for seven days.

Effective purification of ginsenosides from cultured wild ginseng roots,red ginseng, and white ginseng with macroporous resins.

This study was aimed (i) to develop an effective method for the purification of ginsenosides for industrial use and (ii) to compare the distribution of ginsenosides in cultured wild ginseng roots (adventitious root culture of Panax ginseng) with those of red ginseng (steamed ginseng) and white ginseng (air-dried ginseng). The crude extracts of cultured wild ginseng roots, red ginseng, and white ginseng were obtained by using a 75% ethanol extraction combined with ultrasonication. This was followed sequentially by AB-8 macroporous adsorption chromatography, Amberlite IRA 900 Cl anion-exchange chromatography, and Amberlite XAD16 adsorption chromatography for further purification.

Effect of high-dose aspirin on CYP2E1 activity in healthy subjects measured using chlorzoxazone as a probe.

The authors evaluated the effect of high-dose aspirin at a therapeutic dose, using chlorzoxazone as a probe for CYP2E1 enzyme activity. In a randomized, open-label, 2-way crossover study, 10 healthy men were treated 3 times daily for 6 days with 1 g aspirin or placebo. On day 7, 1 dose of 400 mg chlorzoxazone was administered orally.

Genetic polymorphisms and linkage disequilibrium of sulfotransferase SULT1A1 and SULT1A2 in a Korean population: comparison of other ethnic groups.

Aims: To determine the allele frequencies of sulfotransferases (SULTs) 1A1 and 1A2 and their linkage disequilibrium in a Korean population and compare them with those of other ethnic groups.

Methods: Genotypes of the SULT1A1*1, *2, and *3 and SULT1A2*1, *2, and *3 allelic variants were determined in 234 Korean subjects using polymerase chain reaction (PCR)-restriction fragment length polymorphism (RFLP) methods.

Results: Allele frequencies for SULT1A1*1 and *2 were 0.

Effect of quercetin on the pharmacokinetics of rosiglitazone, a CYP2C8 substrate, in healthy subjects.

Previous in vitro studies have demonstrated that quercetin inhibits CYP2C8, but there are no available data to indicate that quercetin inhibits CYP2C8 in vivo. The effect of long-term use of quercetin on the pharmacokinetics of rosiglitazone was evaluated. After administration of quercetin or matched placebo for 3 weeks in a crossover manner, rosiglitazone 4 mg was administered, and the pharmacokinetics of rosiglitazone and N-desmethylrosiglitazone were determined.

Establishment of in vitro test system for the evaluation of the estrogenic activities of natural products.

In order to evaluate estrogenic compounds in natural products, an in vitro detection system was established. For this system, the human breast cancer cell line MCF7 was stably transfected using an estrogen responsive chloramphenicol acetyltransferase (CAT) reporter plasmid yielding MCF7/pDsCAT-ERE119-Ad2MLP cells. To test the estrogenic responsiveness of this in vitro assay system, MCF7/pDsCAT-ERE119-Ad2MLP cells were treated with various concentrations of 17beta-estradiol.

The preventive inhibition of chondroitin sulfate against the CCl4-induced oxidative stress of subcellular level.

Our work in this study was made in the microsomal fraction to evaluate the lipid peroxidation by measuring superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx), and malondialdehyde (MDA) and to elucidate the preventive role of CS in the CCl4-induced oxidative stress. The excessive lipid peroxidation by free radicals derived from CCl4 leads to the condition of oxidative stress which results in the accumulation of MDA. MDA is one of the end-products in the lipid peroxidation process and oxidative stress.

Genomic organization and promoter characterization of the murine dopamine receptor regulating factor (DRRF) gene.

To study the transcriptional mechanisms by which expression of the dopamine receptor regulating factor (DRRF) gene is regulated, a murine genomic clone was isolated using a DRRF cDNA as probe. A 24 kb genomic fragment which comprises 13 kb upstream of the transcription initiation site was sequenced. The promoter region lacks a TATA box and CAAT box, is rich in G+C content, and has multiple putative binding sites for the transcription factor Sp1.
