生物活性 |
Prostaglandin E2 (PGE2) is a hormone-like substance that participate in a wide range of body functions such as the contraction and relaxation of smooth muscle, the dilation and constriction of blood vessels, control of blood pressure, and modulation of inflammation.[1-3] |
In Vitro |
PGE2 显示在受照射和未受照射的 T 淋巴细胞的混合物中抑制 IL 2 的产生。PGE2 (0.1-10 μM) 剂量依赖性地抑制 IL 2 的产生。PGE2 在抑制细胞激活的诱导期起作用。将 T 淋巴细胞与 PGE2 预孵育可诱导抑制 IL 2 生成和 PHA 增殖的细胞[1]。 |
In Vivo |
Prostaglandin E2 可用于动物建模,构建大鼠疼痛模型。PGE2 (0.3 μg/k,ip) 显著减少大鼠体内正在吞噬甲基丙烯酸酯微珠的腹膜巨噬细胞数量[2]。PGE2 (0.1 mg/min,ia) 增加肾血流量。PGE2 在肾血管阻力中产生双相变化,血管舒张从 0.01 mg/min 开始,在约 3 mg/min 时达到最大,而在使用的最高剂量 (20 mg/min) 时,PGE2 诱导肾血管收缩[3]。 |
细胞实验 |
Lymphocytes in CM (1×106 cells/mL) are ditributed in microculture plates (100 μL) in triplicate in the presence of PGE-treated T cells or medium-treated T cells and stimulated with PHA-P at various mitogenic doses. After 72 hr, cultures are pulsed with 1 μCi [3H]thymidine per well (specific activity 5 Ci/mM) for 16 to 18 hr, collected with amicroprecipltator, dried, and counted in a liquid scintillation counter. |
动物实验 |
Male Sprague Dawley rats (200-250 g) are used throughout the study. For 3 consecutive days rats in the experimental groups receive a daily intraperitoneal injection of either PGE2 (0.3 μg/kg body weight (BW)), the prostaglandin inhibitor mecbofenamate (10 mg/kg BW) or the prostaglandin precursor arachidonic acid (0.3 μg/ kg BW). To determine whether or not 0.3 μg/kg BW of a fatty acid produces nonspecific effects, the biologically inactive fatty acid 11, 14, 17-eicosatrienoic acid is also administered to a group of rats. Rats in the control group receive an equivalent volume (2.0 mL/kg BW) of the vehicle. On the third day, 3 mL of a suspension containing 1.2×106 fluorescent methacrylate microbeads/mL of PBS are injected intraperitoneally (ip) into each rat. Six hours later all animals are given ip a regular dose of their respective treatment. Peritoneal exudate cells are harvested 19-22 hr later. |
