Linguatula serrata is a worldwide zoonotic food-borne parasite. The parasite is responsible for linguatulosis and poses a concern to human and animal health in endemic regions. This study investigated the hematological changes, oxidant/antioxidant status and immunological responses in goats and sheep naturally infected with L. serrata. Hematological changes, antioxidant enzymes and malondialdehyde (MDA) levels were measured. The level of inter-leukin-2 (IL-2), IL-4, IL-5, IL-10, and tumor necrosis factor alpha (TNF-α) mRNA expression was investigated in lymph nodes. According to the hemogram results, eosinophils were significantly increased in the infected goats and sheep, and Horizontal Gene Transfer (HGT), hematocrit (HCT), and mean corpuscular hemoglobin concentration (MCHC) were significantly decreased. The levels of MDA and the activity of glutathione peroxidase (GPx) were significantly higher in infected animals than in non-infected animals. However, the activity of superoxide dismutase (SOD) and catalase (CAT) was significantly lower in infected animals than in non-infected animals. A comparison of the cytokine mRNA expression in lymph nodes from infected and non-infected animals showed higher cytokine expression in the infected animals. Infection with L. serrata caused microcytic hypochromic and normocytic hypochromic anemia in goats and sheep. The inconsistent results of immunological changes were found in infected goats and sheep. In both animals, oxidative stress occurred and led to an increase in lipid peroxidation. L. serrata created a cytokine microenvironment biased towards the type 2 immune responses.

Cisplatin (CP) as an important chemotherapeutic drug is used for the treatment of various malignancies; but it has some side effects on central nervous system, in particular hippocampus. The present study was aimed to determine the protective effects of Aloe vera (AV) gel on CP-induced oxidative stress, apoptosis and neurons structure changes in the hippocampus of rats. Forty-eight rats were divided into six groups including control, CP (5 mg kg-1 per week; intra-peritoneally), CP + AV (400 mg kg-1 per day; orally), CP + metformin (200 mg kg-1 per day; orally), AV (400 mg kg-1 per day; orally) and metformin (200 mg kg-1 per day; orally). At the end of treatment, brain samples were obtained for analysis of apoptotic genes expression and anti-oxidant markers as well as histological study. The results showed that CP caused an increase in malondialdehyde level and a decrease in glutathione peroxidase, superoxide dismutase and catalase levels in CP group compared to control. The AV gel could diminish oxidative stress in the hippocampus of CP group and it resulted in down-regulation of Bax, caspase-3 and caspase-8 and up-regulation of Bcl-2 in CP group. It could ameliorate degenerative changes in hippocampus after exposure to CP. Our results showed that AV gel ameliorated oxidative stress, apoptosis and neuronal loss in the hippocampus of rats under CP treatment.
