Kidney and liver injury due to CsA or renal I/R can be significantly reduced by TQ, which resets the oxidant/antioxidant balance of the affected organs through scavenging free radicals and antilipoperoxidative effects.

Abstract. The present study was designed to investigate the therapeutic effects of bee venom (BV) on high-fat diet (HFD)-induced non-alcoholic fatty liver (NAFL) in rats at different levels. Histological manifestations, hepatic lipid content, liver function tests, glucose homeostasis, lipid abnormalities, adipocytokines, lipid peroxidation, disturbed glutathione and antioxidant enzymes systems and dysregulation of Nrf2 transcription factor were assessed. In the present study, the NAFL rats were subcutaneously treated with BV with different doses (0.01, 0.05, 0.1 mg/kg). The results indicated that BV treatment completely normalized the lipid profile values of NAFL rats. Fasting blood sugar, insulin level and homeostatic model assessment of insulin resistance significantly decreased. BV treated rats showed a significantly lower level of all liver enzymes and bilirubin. Moreover, BV treatment significantly increased the levels of active nuclear erythroid factor 2 like 2, glutathione (GSH) (total and reduced), GSH/glutathione disulphide ratio and activities of glutathione reductase, glutathione-S-transferase and glutathione peroxidase (total and Se-dependent). The level of tumor necrosis factor-α was reduced. Treatment showed correction of adiponectin level, and significant downregulation of hepatic triglycerides and cholesterol. At the histological level, BV improved the architecture of liver cells showing normal sinusoids. It may be concluded that BV may represent an interesting therapeutic alternative for the treatment of NAFL disease.

The present study investigated the anti-Toxoplasma effect of chitosan nanoparticles [CS NPs], spiramycin, spiramycin co-administered with metronidazole and spiramycin-CS NPs formulation on the parasite burden and histopathological changes in the liver, spleen and brain in experimentally infected mice. Seventy male Swiss albino mice were classi ed into seven equal groups: healthy control (I), infected untreated control (II), infected group receiving CS NPs (III), spiramycin administered infected group (IV), infected group receiving spiramycin-metronidazole (V), infected receiving 400 mg/kg spiramycin-CS NPs (VI) and infected treated with spiramycin-loaded CS NPs 100 mg/kg (VII). All groups were inoculated intraperitoneally with 2500 T. gondii tachyzoites RH strain except the healthy control group. All groups were sacri ced on the 8th day after infection. Density of the parasite and histopathological examination of the liver, spleen and brain of all treated mice revealed reduction in the mean tachyzoites count as well as decreased in ammation, congestion and necrosis within tissue sections. Spiramycin-loaded NPs displayed the highest signi cant reduction in the pathological insult tailed by spiramycin-metronidazole and CS NPs. In conclusion, spiramycin-loaded CS NPs showed a promising synergistic combination in the treatment of the histopathology caused by toxoplasmosis.
