Dystocia is a critical obstetrical problem in farm animals and is classified into maternal or fetal dystocia. The maternal causes of dystocia include different causes such as uterine torsion (UT), failure of cervical dilation (FCD), and uterine inertia (UI). Maternal dystocia induces massive oxidative stress due to increased production of free radi...

Deltamethrin (DM) is one of the most environmental and industrial pollutants that are toxic to humans, animals, fishes, and birds. The most common sources of human and animal exposure to deltamethrin (DM) are polluted water and food. This study was done to evaluate the nephrohepatic toxicity of deltamethrin. Twenty-four male rats were used. The fir...

Parabens are group of preservatives chemical compounds used in cosmetics, personal hygiene product, food products and pharmaceuticals. In this study the hepatorenal toxicity due to exposure to paraben was evaluated. In this study design Twenty four of albino rats experimentally used. Butyle paraben (BP) orally was given to animals 180 days in dose...

Background and Aim: The reproductive performance of dairy cows is of a high economic value to maintain efficient and sustainable productivity. Postpartum anestrus is one of the major infertility problems that cause limitation of dairy cow reproductive performance and productivity. The previous studies have reported using a polyherbal formulation...

AB S T RA C T: Fascioliasis is caused by two species of trematodes that mainly affect the liver. It belongs to the group of foodbornedisease infections. It is a zoonotic disease, while Anaplasmosis is a tick-borne disease. Both diseases occur worldwideparticularly in regions with intensive animal production. Therefore, the current study aimed to in...

This study we investigated the effects of insulin spray treatment on skin wounds in diabetic rats. Thirty rats were used forexperiment. Rats were divided into 3 groups. group 1 serve as control group. Group 2 was diabetic without treatment.Group 3 was diabetic and treated with insulin spray daily for eight days. Diabetus was inducted by injection o...

Objective: The purpose of this study was to measure the mean concentrations of heavy metals including aluminum (Al), arsenic, nickel (Ni), mercury, lead (Pb), and cadmium (Cd) and to assess the health hazards due to the exposure of cattle/human population to a distinct or the mixture of heavy metals through various sources. Materials and methods: A...

Mekkawy HI, Elmansi AA (2020): Co-administration of vitamin E and selenium in vivo and in vitro ameliorates the toxic effects caused by ivermection and doramectin. Vet Med-Czech 65, 71-83. Abstract: Avermectins are used in animals and humans for their broad-spectrum effects against parasites causing cytotoxicity and damage to the cellular DNA. In t...

Background: Cyclophosphamide (CP) is a selective antibiotic used clinically as an anticancer drug. Treatment with CP exhibits a number of side effects. Here in this study, we explored the toxic effects of CP and the ameliorating effects of Sargassum cinereum in albino rats. Material and methods: Eighteen rats divided into 3 groups (6 rats each) con...

Avermectins are used in animals and humans for their broad-spectrum effects against parasites causing cytotoxicity and damage to the cellular DNA. In this study, we examined the toxicological changes of ivermectin (IVM) and doramectin (DME) with or without the co-administration of vitamin E (Vit. E) and selenium (Se). The drugs used were for animal...

This study was carried out to compare the analgesic effects and haematobiochemical changes produced by the administration of lidocaine, detomidine and lidocaine–detomidine combination in the epidural space of goats. All goats were assigned to all of the three different epidural treatments using a balanced crossover design with two-weeks washout per...

Background: garlic has been used for food and medicine purposes and this recorded in many cultures for thousands of years. Coccidiosis is serious health problem causing destruction of intestinal mucosa. Objective: In this study, we investigated the immunomodulatory and parasiticidal effects of garlic on the coccidiosis caused by Eimeria vermiformis...

ARTICLE INFO In the last decades, the light had been shed on the importance of male reproduction and how to protect it from disease conditions and inflammation which may cause infertility. Accordingly, the mechanism underlying inflammation-mediated infertility must be well clarified. In the present study, an experimental model of acute inflammation...

Here we investigate hematological and biochemical alterations in the burn animals. The values of these parameters are very important in allowing the veterinarians to know how the animal body is responding to the different therapies that being provided? And this will help the veterinary medical staff for proper management with less morbidity and mor...
