Ceratonia siliqua pods (Carob) methanol extract alleviates doxorubicin-induced nephrotoxicity via antioxidant, anti-inflammatory and anti-apoptotic pathways in rats.

Doxorubicin (DOX) is an anti-neoplastic therapy, but its use is limited by its deleterious toxic effects including nephrotoxicity and cardiotoxicity. This work aimed at assessing the potential protective effect of Ceratonia siliqua methanol extract (CME) on DOX-induced nephrotoxicity in 5 groups of Wistar rats. Nephrotoxicity was induced experimentally by intraperitoneal (IP) injection of DOX (15 mg/kg).

The effect of exposure to MoO-NP and common bean fertilized by MoO-NPs on biochemical, hematological, and histopathological parameters in rats.

Nanotechnologies has been used to introduce several beneficial tools in the agricultural field. Herein, the effect of molybdenum oxide nanoparticles (MoO-NPs) was investigated by evaluating the hematological, biochemical, and histopathological parameters in rats orally exposed to MoO-NPs or fed common beans (CB) fertilized by MoO-NPs. In the first study, 18 rats were randomly divided into 3 groups: G1 (control group) was given water orally, while G2 and G3 were administered 10 and 40 ppm MoO-NPs by oral gavage tube, respectively.

Current perspective on veterinary drug and chemical residues in food of animal origin.

The marked increase in the demand for animal protein of high quality necessitates protecting animals from infectious diseases. This requires increasing the use of veterinary therapeutics.

Infective third larval stage (L3) of () were obtained by culturing feces of goat harboring monospecific infection of the parasite.

Beneficial effects of antioxidants in improving health conditions of sheep infected with foot-and-mouth disease.

The effect of multinutrient antioxidant treatment on sheep naturally infected with FMD virus was investigated in terms of general health conditions, serum proteins profile, and antioxidant/oxidant parameters. Twenty diseased sheep were divided into 4 equal groups (n = 5) and underwent certain therapeutic protocols for 8 weeks as follows: GI, infected not treated group; GII, infected and treated with the ideal and usual line of treatment against FMD virus infection; GIII, infected animals supplemented orally zinc methionine at a dose of 5 g/head/day and vitamin E with selenium-enriched yeast at the same dose level; GIV, infected animals received both the ideal treatment and antioxidants. The animals under experiment were clinically evaluated.

Effect of Egyptian propolis on cryptosporidiosis in immunosuppressed rats with special emphasis on oocysts shedding, leukogram, protein profile and ileum histopathology.

Effect of methanolic extract of Balanites aegyptiaca fruits on enteral and parenteral stages of Trichinella spiralis in rats.

There is a considerable interest in developing new anthelmintic drugs including those from medicinal plants due to increasing evidence of parasitic resistance against present anthelmintic drugs and decreasing activity against encapsulated larval stages of parasites. This study was carried out to assess, for the first time, the effectiveness of methanolic extract of Balanites aegyptiaca (BAE) fruits against different stages (pre-adult, migrating larvae, and encysted larvae) of Trichinella spiralis in rats compared with commonly used anthelmintic albendazole. Oral administration of BAE at a dose of 1,000 mg/kg b.
