O presente trabalho tem por objetivo relatar um caso de envenenamento botrópico em um equino, fêmea, seis anos de idade, da raça Quarto de Milha, pesando 460kg, que foi atendido no hospital veterinário da FCAV/Unesp, Campus de Jaboticabal, SP. No exame clínico, observou-se aumento bilateral de narina, com extrema sensibilidade ao toque, presença das marcas da presa da serpente na região rostral de focinho, mucosas róseas com petéquias. No exame de sangue, pôde-se detectar alteração no tempo de coagulação sanguínea (>30 minutos). O animal permaneceu internado, sendo instituída a seguinte terapia: soro antiofídico polivalente, transfusão de plasma sanguíneo equino, fluidoterapia intensa, flunixin meglumine e sulfa associado ao trimetoprim. A associação da transfusão de plasma sanguíneo equino ao tratamento convencional foi de extrema importância para correção da coagulopatia causada pelo acidente ofídico. A égua apresentou melhora clínica e resolução do quadro de envenenamento após cinco dias da internação.(AU)

This study aims to report a case of blood plasma association with the treatment of bothrops poisoning in an equine, female, six years of age, Quarter Horses, weighing 460 kg, which was served in the veterinary hospital of the FCAV/UNESP, Jaboticabal/SP. Clinical examination showed bilateral increase in nostrils, with great sensitivity to touch, presence of snake prey marks the rostral region of the snout, mucous rosy and with petechiae. Blood samples showed changes in blood clotting time (> 30 minutes). The animal remained in hospitalization with the following treatment: polyvalent antivenom, blood plasma transfusion, intensive fluid therapy, flunexim meglumine and sulfa associated with trimethoprim. The association of transfusion equine blood plasma to conventional treatment was extremely important for correction of coagulopathy caused by snakebite. The mare showed clinical improvement and resolution of poisoning symptoms after five days of hospitalization.(AU)

Accidents involving toad poisoning are frequent and dogs are the most common victims; they become poisoned by biting or ingesting a toad. When released in the organism, the venom is absorbed by both the oral mucosa and the digestive tract, initiating its toxic action. The aim of this work was to evaluate the clinical and electrocardiographic aspects of dogs subjected to experimental toad poisoning, as well as their response to treatment with propranolol. Twenty dogs were divided into two groups, a control group (n = 5) and a poisoned group (n = 15). After general anesthesia, the control group received a placebo, while the poisoned group received a venom aliquot through an orogastric tube. Results were tested through multivariate analysis (p < 0.05). The animals in the poisoned group had gastrointestinal symptoms including emesis, intense salivation, hyperemic or congested oral mucosa and pasty diarrhea. Non-responsive mydriasis, nystagmus, depression, stupor, tachypnea, opisthotonus and ataxia were also manifested by 100 percent of the poisoned animals. Affected dogs had an increase in blood pressure, statistically significant throughout study. Five poisoned animals developed ventricular tachycardia and were treated with propranolol (0.5 mg/kg IV). All propranolol-treated animals returned to normal sinus rhythm, which evidences the efficacy of this drug to treat ventricular arrhythmias caused by toad venom.

Toad poisoning is frequent in dogs, but has been infrequently addressed in published case reports and review articles. Dogs can be poisoned when they bite a toad or otherwise ingest the venom. The venom effects manifest soon after the accident, since the toxin is rapidly absorbed by the mucous membrane of the digestive system. Hospital records of three dogs, diagnosed with toad poisoning, were retrospectively reviewed from January 2005 to July 2007. Poisoned dogs may present only local irritation or systemic signs in the gastrointestinal, cardiac and neurological systems. All three cases presented herein had clinical signs of gastrointestinal alterations including vomiting, sialorrhea and diarrhea. Two dogs developed abnormal cardiac rhythm and two exhibited neurological signs. A poisoned animal requires emergency care and symptomatic therapy with intense monitoring of its clinical parameters. Although there have been reports on the low mortality of dogs poisoned by toads, one animal died even after appropriate therapy. The severity of clinical signs and the risk of death must be considered by the veterinarian.

Healing is a complex process with many interfering factors. The objective of this work was to evaluate regeneration strenght of non-pregnant adult dog uterus when snake venom derived fibrin adhesive is used to reinforce hysterorrhaphy. Maximum limit and rigidity were analyzed. Twenty uterine horns from 10 dogs were hysterotomized and distributed into 2 groups. Hysterorrhaphy was performed using the Shimieden-Cushing double layer suture. In one group, animals received snake venom derived fibirn adhesive as reinforcement. Although neither variable was significantly different, our results showed higher rigidity values in the adhesive group. This can be attributed to the adhesive's effect on organ elasticity or to more granulation tissue formed in the uterine scar

This study evaluated the use of fibrin glue derived from snake venom in the healing process after canine histerorrhaphy. Three groups of four animals were submitted to uterine hysterotomy followed by wound closure. In Group 1, double-layer suture was used, the first with Schimieden pattern, the second with Cushing pattern; in Group 2, only fibrin glue; and in Group 3, the same as for Group 1 but with fibrin glue as suture reinforcement. Results indicated that fibrin glue produced less inflammation in the exudative phase, and exacerbated deposition of connective tissue and angiogenesis in the proliferative and maturation phases of the healing process, favoring its evolution.
