Effects of the acute exposition to glyphosate-based herbicide on oxidative stress parameters and antioxidant responses in a hybrid Amazon fish surubim (Pseudoplatystoma sp)

The aim of this study was to investigate the effects of acute glyphosate (active ingredient) exposure on the oxidative stress biomarkers and antioxidant defenses of a hybrid surubim (Pseudoplatystoma sp). The fish were exposed to different herbicide concentrations for 96 h. The thiobarbituric acid-reactive substances (TBARS), protein carbonyls and antioxidant responses were verified. The 15 mg a.p L-1 of herbicide resulted in the death of 50% of the fish after 96 h. An increase in liver and muscle TBARS levels was observed when fish were exposed to the herbicide. The protein carbonyl content was also increased in the liver (4.5 mg a.p L-1 concentration) and brain (2.25 mg a.p L-1 concentration). The antioxidant activities decreased in the liver and brain after exposure to herbicide. Levels of ascorbic acid in the liver (2.25 mg a.p L-1 and 4.5 mg a.p L-1 concentrations) and brain (2.25 mg a.p L-1 concentration) were increased post-treatment. Levels of total thiols were increased in the liver and brain (2.25 mg L-1 and 7.5 mg a.p L-1, respectively). Glyphosate exposure, at the tested concentrations affects surubim health by promoting changes that can affect their survival in natural environment. Some parameters as TBARS and protein carbonyl could be early biomarkers for Roundup exposure in this fish species. (C) 2014 Elsevier Inc. All rights reserved.

Criptosporidiose em animais domésticos: aspectos epidemiológicos

Studies related cryptosporidiosis will be essential, due to its relevance in public health and pathogenicity in pets and production animals. Over the past 20 years, there has been a rapid expansion of research involving the Cryptosporidium genus, largely related to molecular studies, providing a description of various species, genotypes and subtypes of the parasite. The molecular characterization of isolates from different sources (human, animal and environmental) has been widely used in order to investigate the potential zoonotic of this protozoa. The documented transmission forms from animals to humans, from person to person, through water intake or water for the leisure that are directly or indirectly contaminated with sporulated oocysts. The high rate of animals naturally infected and the susceptibility by protozoan, justify the importance of attending to the occurrence of this disease. So are demonstrated epidemiological aspects of this zoonotic disease in domestic animals.

Electrocardiographic evaluation of the degree of sedation and the isolated use of methadone in healthy dogs

Objective: The present study aimed to investigate the influence of methadone on cardiorespiratory parameters, electrocardiogram and clinical sedation in dogs. Further possible side effects are reported.Study designProspective experimental cross-over study.DogsEight, 1-4-year-old, various breeds of dogs of both genders weighing 9-36kg.MethodsEach dog was treated three times: methadone 0.3mgkg(-1) (M0.3), 0.5mgkg(-1) (M0.5) and 1.0mgkg(-1) (M1.0) intramuscularly. Respiratory rate, heart rate and arterial blood pressure were recorded as well as electrocardiographic evaluation of lead II. Clinical sedation in each treatment received a score (0-3) after drug administration and at 30minute intervals until scores and measurements returned to baseline values.ResultsA significant decrease in heart rate was seen with each dose of methadone and bradycardia (HR<60bpm) was noted in a few dogs at each dose. A clinically significant arrhythmia occurred in one dog at 1mgkg(-1) that required reversal with butorphanol. There was no significant difference in SAP, MAP and DAP between treatments. Some side effects such as salivation, defecation, vocalization and panting, after administration of methadone were observed. There were no differences in mean values of heart rate, P-wave and QRS complex duration and QT interval between treatments.Conclusion and clinical relevanceMethadone administration was associated with panting and a decrease in heart rate at all doses tested in this study. The cardiac rhythm should be monitored carefully in dogs when methadone is administered on its own, especially at higher doses.
