Protective effect of Zataria multiflora on hepatotoxicity induced by cisplatin in mice

Background and objectives: Cisplatin (CP), the chemotherapy drug, is used for the treatment of many types of cancer but causes hepatotoxicity. Zataria multiflora Boiss. (ZM), is a widely used herbal medicine with potent antioxidant properties. This study aimed to assess the protective effect of Zataria multiflora against cisplatin-induced hepatotoxicity. Methods: In this experimental study, thirty-two male mice were randomly divided into four groups. The control group; ZM group which received ZM (200 mg/kg) during 7 days by gavage; CP group which received CP (10 mg/kg) intraperitoneally in 5th day of the study and ZM+CP group. Serum parameters such as alanine transaminase (ALT), aspartate transaminase (AST) and alkaline phosphatase (ALP) and also malondialdehyde (MDA), glutathione (GSH) and protein carbonyl (PC) levels in liver tissue of mice, histopathological and immunohistochemical assays were examined to determine hepatotoxicity. Results: CP caused significant (

Ameliorative effect of Zingiber officinale on diazinon -induced testicular toxicity: A biochemical, histopathological, and immunohistochemical study

Background and objectives: Diazinon (O,O-diethyl O-2-isopropyl-6- methyl pyrimidinyl-4-g-1- phosphorothioate) is one of  the organophosphate insecticides for different agricultural and gardening uses, which can be highly toxic. Zingiber officinale(ginger), a spice and herbal medicine, has antioxidant and anti-inflammatory properties. This study has investigated the effects of ginger against DZN-induced testicular toxicity. Methods: Thirty two adult male mice were randomly divided into four groups. The control group; ginger group (200 mg/kg); DZN group (10 mg/kg) and ginger + DZN group. Ginger and DZN were received for 30 consecutive days by gavage and DZN treat one hour after receiving ginger. Sperm parameters, testosterone levels, biochemical, histopathological and immunohistochemical assays of testis were evaluated. Results: The results revealed that treatment with DZN caused significant damage of sperm parameters (sperm motility, count, viability rate and abnormalities), increased oxidative stress (increased MDA and decreased GSH level), significant histopathological changes and decreased Johnsen’s Score, testosterone level and increased caspase-3 immunoreactivity. Ginger preserved sperm parameters and mitigated the toxic effects of DZN. Also, pretreatment with ginger significantly reduced caspase-3 immunoreactivity. Conclusion: Our results concluded that ginger probably with its antioxidant activity and scavenging free radicals protect against DZN-induced testicular toxicity

The Protective Effect of Zinc against Hepatotoxicity Induced by Arsenic During Gestation and Lactation in Rat Neonate

BACKGROUND AND OBJECTIVE: Arsenic (Ar) by induced oxidative stress in gestation and lactation period can cause teratogenicity properties in the neonate. On the other hand, the evidence suggests the antioxidant effect of zinc (Zn). So, the aim of present study was to evaluate protective effect of Zn against Ar-induced hepatotoxicity during gestation and lactation in rat neonate. METHODS: In this experimental study, 24 adult wistar rats of the 35 mice that their pregnancy was confirmed, randomly divided into four groups including:I) Control group; II) Ar group, (20 mg/kg/day); III) Zn group; (5 mg/kg/day) and IV) Ar+Zn group. Ar and Zn administration was daily with intragasticaly method. At the end of the experimental period (42 days: 21 of gestation and 21 of lactation) after anesthesia hepatic samples were taken for biochemical assessment of malondialdehyde (MDA), glutathione (GSH) and histopathological assessment. FINDINGS: The MDA and GSH mean±SD in Ar group was 41.56±7.2 and 7.05±1.36, respectively. Also, in Ar+Zn group assessed 26.26±1.84 and 13.79±1.34, respectively. This difference was significant between groups (P<0.05). Also, the histopathological finding by using scoring system in Ar+Zn in compare to Ar group was significant (P<0.01). CONCLUSION: Our findings showed that administration of Zn as antioxidant can decreased the toxically and teratogenic effect of Ar during gestation and lactation
