一般描述
2,3,5-三苯基氯化四氮唑（TTC）是一种广泛用于固体培养基中微生物菌落计数的染料。这种染料在氧化形式下是无色的，当被微生物还原时，由于形成了甲臜，因此变为红色。活的微生物，例如大肠杆菌和其他大肠菌群，通过酶促作用减少TTC，形成红色的甲臜，保留在细胞的颗粒内部。强烈建议在检测巴氏杀菌奶时使用TTC，因为在巴氏杀菌奶中有很大比例的微生物无法减少 TTC，而这些微生物无法通过实验室程序检测到。较高浓度的 TTC 可对革兰氏阳性菌的生长起抑制作用。
应用
2,3,5-三苯基氯化四氮唑（TTC）溶液是一种氧化还原指示剂，可以帮助指示细胞呼吸、识别活细胞和非活细胞，以及识别能够在固体培养基上还原 TTC 的微生物

Ischemia-reperfusion (I/R) injury, often encountered clinically, results in myocardial apoptosis and necrosis. Hydrogen sulfide (H(2)S) is produced endogenously in response to ischemia and thought to be cardioprotective, although its mechanism of action is not fully known. This study investigates cardioprotection

Increased expression of several subtypes of prostaglandin E(2) receptors (EP1-4) has recently been described in clinical and experimental myocardial ischaemia/reperfusion (I/R) injury. However, their pathophysiological significance in I/R remains obscure. Thus, we determined whether the activation of the prostanoid receptor
