Earthworm extract has shown anticancer characteristics. In the present study, we examined the effect of chronic treatment with a high dose of earthworm (Eisenia andrei) extract (EE) on cell proliferation and neuroblast differentiation in the hippocampal dentate gyrus (DG) of 3-week-old mice using 5-bromo-2'-deoxyuridine (BrdU) and Ki-67 immunohistochemistry for cell proliferation and doublecortin (DCX) immunohistochemistry for neuroblast differentiation, respectively. BrdU-, Ki-67-, and DCX-immunoreactive cells were easily detected in the subgranular zone of the DG in vehicle (saline)-treated mice. However, BrdU-, Ki-67-, and DCX-immunoreactive cells in the 500 mg/kg EE-treated mice decreased distinctively compared to those in the vehicle-treated mice. In addition, brain-derived neurotrophic factor (BDNF) immunoreactivity and its protein level decreased markedly in the DG of the EE-treated group compared to those in the vehicle-treated group. These results indicate that chronic treatment with high dose EE decreased cell proliferation and neuroblast differentiation, and that BDNF immunoreactivity decreased in the DG of EE-treated mice.

OBJECTIVETo study the factors influencing the activity of fibrinolytic enzymes from earthworm and to obtain the better way to extract fibrinolytic enzymes as well as keep its optimum activity.

METHOD75% alcohol, 0.9% NaCl and 10% saccharose was used to extract the crude fibrinolytic enzymes from earthworm, the method of urokinase gelose-fibrin plate was used to measure the activity of fibrinolytic enzymes from earthworm. and the method of 3,3'-diaminobezidine tetrahydrochloride colorimetry to was used measure the content of selenium. The method use ts of measuring the content of arsenic was silver diethyldithiocarbamate colorimetry.

RESULTThe fibrinolytin of earthworms reared with cattle soils had higher activity than that reared with garbage. The arsenic in the earthworm's body could improve the activity of earthworm's fibrinolytin. However, the selenium had litter influence on it. Among the three methods of extraction, the 75% alcohol one was the most efficient, the 0.9% NaCl was next, and the 10% saccharose was the lowest. The influence of dialysis on the activity of fibrinolytin was less than that of ultrafiltration, when the earthworm's fibrinolytin enzyme was further sublimated.

CONCLUSIONThe activity of the earthworm's fibrinolytin will be increased earthworm is reared with the fitting baits and when appropriate methods, of extraction and purification are used.

In the present study,fresh Guangdilong( GD),originating from Pheretima aspergillum,was taken as the object. The total proteins from GD were firstly separated by SDS-PAGE according to their molecular weights and in-gel digestion was then performed.After that,the peptides were analyzed by nano LC/orbitrap fusion lumos high resolution mass spectrometry( nano LC/orbitrap fusion lumos HR-MS). Protein identification was implemented by comparison with Annelida. fasta database using Proteome Discoverer software.As a result,386 proteins were tentatively identified,including chain F,globin B chain,glyceraldehyde-3-phosphate dehydrogenase,fibrinolytic protein,and so on. Most of the proteins took part in cell structure and energy metabolism,and fibrinolytic protein and lombricine kinase might be related to fibrinolytic activity. Protein classification based on gene ontology was carried out using PANTHER and KEGG for metabolic pathway enrichment. The results indicated that these proteins were related to diverse signal transduction pathways,including metabolic pathways,central carbon metabolism,biosynthesis of amino acids,ribosome,glycolysis,citrate cycle( TCA cycle),and so on. This study would lay the foundation for the further research on the proteins in GD and also their functions.

To investigate the intestinal absorption of a fibrinolytic and proteolytic lumbrokinase extracted from Eisenia andrei, we used rat everted gut sacs and an in situ closed-loop recirculation method. We extracted lumbrokinase from Eisenia andrei, and then raised polyclonal antibody against lumbrokinase. Fibrinolytic activity and proteolytic activity in the serosal side of rat everted gut sacs incubated with lumbrokinase showed dose- and time-dependent patterns. Immunological results obtained by western blotting serosal side solution using rat everted gut sacs method showed that lumbrokinase proteins between 33.6 and 54.7 kDa are absorbed mostly by the intestinal epithelium. Furthermore, MALDI-TOF mass spectrometric analysis of plasma fractions obtained by in situ recirculation method confirmed that lumbrokinase F1 is absorbed into blood. These results support the notion that lumbrokinase can be absorbed from mucosal lumen into blood by oral administration.

Two isolates of Tricholoma matsutake T-008 and T-034, preserved in Entomopathogenic Fungal Culture Collection (EFCC) of Korea, were used in the present study. The isolates had 100% Bootstrap homology with Tricholoma matsutake U62964 and T. matsutake AB188557 and AF309538 preserved in Gene Bank of NCBI. Mycelial growth of T. matsutake was highest in TMM and MYA at 25degrees C. The highest dry wt. of mycelium was obtained after 65 days of culture, when 6 mycelial discs were inoculated in 100 ml of broth in 250 ml shaking flask. Mycelial mats were observed in clumped condition at the inoculation sites of pine forest after two weeks of inoculation. After 5 months of inoculation, mycelia mats were observed growing inside soil and walls of a few inoculation sites, while mycelial mats growth up to 5~8 cm were observed in the roots of pine tree after 6 months. The survival rate of the inoculum was about 40% of the total inoculation sites. The survival rate was found below 20% when the mycelium was inoculated in the summer. The reasons for low survival rates of the mycelium were mainly due to dry season and the soil-borne small animals such as earthworm and mole. After one year of inoculation, no external difference was observed between the artificially inoculated mycelia and the naturally existing mycelia of T. matsutake. The present study showed that fruiting bodies of T. matsutake could be produced by artificial inoculation under the appropriate environmental conditions.

Through literature analysis of Pheretima and its origin-related earthworm,this study summarized the progress on Pheretima in textual criticism of origin,origin identification,effective components,detection of harmful components,and pharmacological effects,which can lay a basis for further research on Pheretima. Through literature research,the authors found that Pheretima was first recorded in Secret Formulary for Traumatology and Fracture Taught by Immortal written by LIN Daoren in Tang Dynasty rather than the Taiping Holy Prescriptions for Universal Relief in Song Dynasty. The latest techniques for origin identification include microscopic trait identification,DNA barcoding,and HPLC. The main effective components of Pheretima are proteins,polypeptides,enzymes,nucleotides,amino acids,and trace elements. According to recent studies,Pheretima has anti-pulmonary and anti-renal interstitial fibrosis,respiratory syncytial virus-inhibiting,human hypertrophic scar fibroblast proliferation-suppressing,and mouse embryonic fibroblast proliferation-promoting effects. Moreover,Pheretima can prevent colitis-induced colon cancer by inhibiting the activation of COX-2/PGE2/β-catenin signaling pathway. METHODS:: for detecting the harmful components and their residues( organic pollutant polychlorinated biphenyl,heavy metals) and bacteria in Pheretima,have been established. Pheretima,mainly derived from wild earthworms,has remarkable clinical efficacy. However,the wild resource is in short supply and artificial culture is expected to be a promising solution.
