[Effects of Genistein on Whole Genome Expression Profiles of Mice Testes Tissue Cultured ].

Objective: To investigate the effects of Genistein (Gen) on the whole expression profiles of testes in mice by using the gene chip technology,and analyze the mechanism how Gen exerts testis on gene level.

Methods: The testicular tissues of suckling mice were cultured in vitro,and separated into control group and Gen group with the dose of 5 μmol/L. After 72 h of culture,we extracted the total RNA and purified it,then detected the gene expression by using Agilent gene array.

[The Effects of All-trans Retinoic Acid on the Expression of Inflammatory Cytokines and Cartilage Damage Related Protease in Rats with Collagen Induced Arthritis].

Objectives: To investigate the effects of all-trans retinoic acid (ATRA) on arthritis and the expressions of inflammatory cytokines and cartilage damage related proteases of the collagen-induced arthritis model (CIA) rats .

Methods: The CIA model of rheumatoid arthritis was induced with C2 and incomplete Freund's adjuvant. The rats were randomly divided into control group, CIA model group and two ATRA dose groups (ATRA 0.

[Prophylactic administration of all-trans retinoic acid alleviates inflammation in rats with collagen-induced arthritis].

Objective: To investigate the effects of prophylactic administration of all-trans retinoic acid (ATRA) in relieving inflammation in a rat model of collagen-induced arthritis (CIA).

Methods: Female Wistar rats (6 to 8 weeks old) were randomly divided into normal control group, solvent control group, and prophylactic ATRA treatment (0.05, 0.

The physiological responses of Vallisneria natans to epiphytic algae with the increase of N and P concentrations in water bodies.

To reveal the mechanism of submerged plants decline in progressively eutrophicated freshwaters, physiological responses of Vallisneria natans to epiphytic algae were studied in simulation lab by measuring plant physiological indexes of chlorophyll content, malondialdehyde (MDA) content, and superoxide dismutase (SOD) activity based on a 2 × 4 factorial design with two epiphytic conditions (with epiphytic algae and without) and four levels of N and P concentrations in water (N-P[mg.L(-1)]: 0.5, 0.
