We investigated the protective role of ceftriaxone plus sulbactam with VRP1034 (Elores) on hematological, lipid peroxidation, antioxidant enzymatic activities and Cd levels in the blood and tissues of cadmium exposed rats. Twenty-four male rats were divided into three groups of eight rats each. The control group received distilled water whereas group II received CdCl2 (1.5 mg/4 ml/body weight) through gastric gavage for 21 days. Group III received CdCl2 and was treated with ceftriaxone plus sulbactam with VRP1034 for 21 days. The hematological, biochemical, lipid peroxidation levels and enzymatic parameters were measured in plasma and tissues (brain, liver and kidney) of all groups. The Cd, Zn and Fe levels were measured in blood and tissues of all groups. Our findings showed significantly decreased cadmium (p<0.001), malonaldialdehyde (p<0.001) and myloperoxidase (MPO) levels along with significantly increased hemoglobin (p<0.01), RBC (p<0.05), hematocrit (p<0.05) levels and all antioxidant enzymatic activities (SOD, CAT, GR, GPx) in plasma and tissues of ceftriaxone plus sulbactam with VRP1034 treated group as compared to cadmium exposed group. Delta aminolevulinate dehydratase (δ-ALAD) activity was significantly (p<0.001) increased in the blood of ceftriaxone plus sulbactam with VRP1034 treated group as compared with cadmium exposed group. The levels of hepatic and renal parameters were significantly (p<0.001) decreased in ceftriaxone plus sulbactam with VRP1034 treated group as compared to cadmium exposed group. These findings indicate that ceftriaxone plus sulbactam with VRP1034 acts as a potent free radical scavenger and exhibits metal chelating properties that reduce free radical mediated tissue injury and prevent dysfunction of hepatic and renal organs during metal intoxication.
我们研究了头孢曲松加舒巴坦与VRP1034(Elores)对镉暴露大鼠血液及组织中的血液学指标、脂质过氧化、抗氧化酶活性和镉水平的保护作用。将24只雄性大鼠分为三组,每组8只。对照组给予蒸馏水,而第二组通过胃管给予CdCl2(1.5毫克/4毫升/体重),持续21天。第三组给予CdCl2,并同时用头孢曲松加舒巴坦与VRP1034治疗21天。测定了所有组血浆及组织(脑、肝和肾)中的血液学、生化、脂质过氧化水平和酶学参数。测定了所有组血液及组织中的镉、锌和铁水平。我们的研究结果显示,与镉暴露组相比,头孢曲松加舒巴坦与VRP1034治疗组的血浆及组织中镉(p<0.001)、丙二醛(p<0.001)和髓过氧化物酶(MPO)水平显著降低,同时血红蛋白(p<0.01)、红细胞(p<0.05)、血细胞比容(p<0.05)水平以及所有抗氧化酶活性(超氧化物歧化酶、过氧化氢酶、谷胱甘肽还原酶、谷胱甘肽过氧化物酶)显著升高。与镉暴露组相比,头孢曲松加舒巴坦与VRP1034治疗组血液中的δ-氨基乙酰丙酸脱水酶(δ-ALAD)活性显著升高(p<0.001)。与镉暴露组相比,头孢曲松加舒巴坦与VRP1034治疗组的肝肾功能参数水平显著降低(p<0.001)。这些研究结果表明,头孢曲松加舒巴坦与VRP1034可作为一种有效的自由基清除剂,并具有金属螯合特性,可减少自由基介导的组织损伤,预防金属中毒期间肝肾功能障碍。
