چکیده

Chemoprotection by diet-derived antioxidants has emerged as a cost-effective approach in preventing genotoxicity and carcinogenicity. In this study, we investigated the protective effects of S-allylcysteine (SAC) and lycopene against N-methyl-N'-nitro-N-nitrosoguanidine (MNNG)-induced genotoxicity. Quantification of bone marrow micronuclei and chromosomal aberrations in male Wistar rats was used to monitor the protective effects of SAC and lycopene. Intragastric administration of MNNG (40 mg/kg) induced a significant increase in the frequency of micronuclei and chromosomal aberrations. Although pretreatment with SAC and lycopene significantly reduced the frequency of MNNG-induced bone marrow micronuclei and chromosomal aberrations, the combination of SAC and lycopene exerted a greater protective effect. These findings indicate that antioxidants such as SAC and lycopene, are effective chemoprotective agents against genotoxicity and carcinogenicity especially when used in combination.

Lycopene Enhances Antioxidant Enzyme Activities and Immunity Function in N-Methyl-N′-nitro-N-nitrosoguanidine–Induced Gastric Cancer Rats

To investigate anticancer effect of lycopene, we examined the effects of lycopene on the oxidative injury and immunity activities of N-methyl-N'-nitro-N-nitrosoguanidine (MNNG)-induced gastric cancer rats. The animals were divided into five groups. Group I served as the normal control and was given corn oil orally for 20 weeks. Group II were induced with MNNG 200 mg/kg body weight by oral gavag...

Effect of Lycopene on Cyclophosphamide-Induced Hemorrhagic Cystitis in Rats

Background: Cylophosphamide is used alone or in combination with other drugs for treatment of neoplastic diseases. Hemorrhagic cystitis is a major potential toxicity and dose limiting side effect of cyclophosphamide. The aim of this study was to evaluate the effects of lycopene compared with some antioxidants for the prevention of cyclophosphamide induced hemorrhagic cystitis in rats. Methods: ...

Protective Effects of Lycopene and Tomato Extract Against Doxorubicin-Induced Cardiotoxicity

       The protective effect of tomato extract and lycopene on acute doxorubicin-induced myocardial toxicity was evaluated in mice. Doxorubicin toxicity, induced by a single intraperitoneal injection (15 mg/kg), was revealed by elevated serum CPKMB and histopathological observations. Tomato extract (1.2 and 2.4 g/kg, i.p.) and lycopene (1.7 and 3.5 mg/kg, i.p.), prevented the rise in serum CPKM...

Effect of prolonged administration of gastrin on experimental carcinogenesis in rat colon induced by intrarectal instillation of N-methyl-N'-nitro-N-nitrosoguanidine.

The effect of tetragastrin on the incidence and histology of colonic tumors induced by intrarectal instillation of N-methyl-N'-nitro-N-nitrosoguanidine was investigated in Wistar rats. Prolonged administration of tetragastrin in depot form during and after treatment with N-methyl-N'-nitro-N-nitrosoguanidine resulted in a significant reduction in the incidence of colonic tumors in Experimental W...

Helicobacter pylori infection enhances glandular stomach carcinogenesis in Mongolian gerbils treated with chemical carcinogens.

Helicobacter pylori (Hp) is thought to be a stomach carcinogen from epidemiological findings. To determine the effects of infection with the bacteria on experimental carcinogenesis, a study of the glandular stomach of Mongolian gerbils (MGs) was performed. Male MGs were treated with N-methyl-N'-nitro-N-nitrosoguanidine followed by inoculation with Hp or infected with Hp followed by N-methyl-N'-...
