产品描述 Ceftiofur hydrochloride (U-67279A) is the hydrochloride salt form of ceftiofur, a semisynthetic, beta-lactamase-stable, broad-spectrum, third-generation cephalosporin with antibacterial activity.
体外活性 Ceftiofur can downregulate tumor necrosis factor-alpha (TNF-alpha), interleukin-1beta (IL-1beta), and interleukin-6 (IL-6), but did not affect interleukin-10 (IL-10) production. Ceftiofur significantly inhibits extracellular signal-regulated kinase (ERK), p38, and c-jun NH(2)-terminal kinase (JNK) phosphorylation protein expression in RAW 264.7 cells. Ceftiofur also inhibits p65-NF-kappaB translocation into the nucleus in RAW 264.7 cells. [1]
体内活性 Ceftiofur treatment is associated with a significant decrease in rectal temperature and diarrhea in neonatal calves. Ceftiofur results in a significant decrease in fecal shedding of Salmonella organisms in neonatal calves. [2] Ceftiofur hydrochloride (intrauterine (i.u.)) reduces the prevalence of positive uterineculture in cows with clinical endometritis (29.0 vs. 51.4%) and reduces the overall prevalence of Arcanobacterium pyogenes (1.0 vs. 7.6%) at 51 d in milk (DIM) . Ceftiofur hydrochloride reduces the prevalence of uterine infection in cows with clinical endometritis, and the prevalence of A. pyogenes, but does not affect the prevalence of subclinical endometritis or fertility of dairy cows already receiving PGF(2alpha). [3] Ceftiofur hydrochloride (i.m. injection) results in C(max) of 11.8 mg/mL at 1-4 hours after injection, the mean area under the curve (AUC) of 216 m g x h/mL in pigs. [4] Ceftiofur hydrochloride (2.2 mg of CE/kg, SC or IM, once daily for 5 days) is efficacious for treatment of acute postpartum metritis (APM) in dairy cows. [5]

TargetMol Calculator 体内实验配液计算器

请在以下方框中输入您的动物实验信息后点击计算,可以得到母液配置方法和体内配方的制备方法: 比如您的给药剂量是10 mg/kg,每只动物体重20 g,给药体积100 μL,一共给药动物10 只,您使用的配方为5% DMSO+30% PEG300+5% Tween 80+60% ddH2O。那么您的工作液浓度为2 mg/mL。

母液配置方法:2 mg 药物溶于 50 μL DMSO (母液浓度为 40 mg/mL), 如您需要配置的浓度超过该产品的溶解度,请先与我们联系。

体内配方的制备方法:取 50 μL DMSO 主液,加入 300 μL PEG300, 混匀澄清,再加 50 μL Tween 80,混匀澄清,再加 600 μL ddH2O, 混匀澄清。

第一步:请输入动物实验的基本信息
