查询词典 dose

Methods Animals were randomly and equally divided into five groups: saline control group, positive drug control group, low-dose, medium-dose and high-dose crocetin group. Animals were anesthetized with urethane (1.2 g/kg), then followed by the perfusion of aconitine (10 μg/mL) through caudal vein in rats, or of ouabain (9 μg/mL) through external jugular vain in guinea pigs in a constant velocity of 0.1 mL/min, and the emergence time of ventricular fibrillation, ventricular extrasystole, ventricular tachycanlia and cardiac arrest were then detected and recorded. The recorded time was then translated to the cumulated amount of aconitine and ouabain. Experimental arrhythmia was induced by rapid injection of 4% CaCl2 (140 mg/kg), and the emergence time, persistence time, incidence and death of arrhythmia after the administration were observed.

RESULTS The proliferation of fibroblasts was inhibited by K102 in vitro. A dose-dependent antagonistic effect was found between K102 and bFGF. The serum levels of ALT, AST and the liver hydroxyproline level in the treated groups were lower than that in the CCl4 model group. Pathological examination showed a slight fatty degeneration and hydropic degeneration was observed in the group treated with the high dose K102, the low dose K102, and the control group.

结果体外生物活性检测：K102明显抑制成纤维细胞的生长，bFGF对K102有一定拮抗作用，且具有剂量依赖性；体内生物活性检测：治疗给药组血清ALT，AST和肝组织羟脯氨酸含量较CCl4模型组明显改善。

Methods: Gastric cancer model of nude mice were established by transplanting human gastric cancer cell line (BGC-823) into hypoderm at right armpit, and then the cancer-beating mice were divided randomly into 5 groups: model group, cyclophosphamide group, and 3 Ad treated groups (high-dose, middle-dose, and low-dose groups).
