Propolis addition to mupirocin regimen was found to result in more profound reduction in bacterial cell count and inflammatory response compared with the rest of the treatment modalities.

The aim of the current study was to evaluate the effects of five different treatment combinations to find out whether propolis could be an alternative or an adjunctive treatment, in experimental Pseudomonas aeruginosa keratitis. Intrastromal P. aeruginosa strains were given to both eyes of 20 young New Zealand white rabbits. The rabbits were randomly divided equally into five treatment groups; ciprofloxacin and dexamethasone drops (C+D), ciprofloxacin drop (C), ciprofloxacin and propolis drops (C+P), propolis drop (P), 3% ethanol drop (control), respectively. Directly before the first treatment and 108 h after inoculation, the eyes were examined by slit lamp to assess the corneal opacity and rabbits were sacrificed for bacterial count. The mean corneal opacity scores and the mean bacterial counts log cfu/ml were significantly different in the treatment groups (P=0.001; ANOVA). According to post hoc tests for both the mean bacterial counts and corneal opacity scores, C+D, C, C+P groups were found to be statistically the same (P>0.05), and although the P group had significantly better scores than the control group it did not reach the scores of the rest of the treatment groups (P<0.01). We conclude that propolis may be a useful adjunctive agent but should not be regarded as a replacement for traditional antibiotic therapy for P. aeruginosa keratitis in rabbits.

Background: In veterinary surgical operations for cats and dogs, inhalation anaesthesia is known to be a good option for general anaesthesia in long operations or emergency cases. Studies have revealed that during inhalation anaesthesia, the heart and respiratory functions of the animals are more stable compared to injectable anaesthesia. However, there are few studies performed with the use of inhalation anaesthesia in ruminants. In this research, the goal is to evaluate the effects of isoflurane and sevoflurane after induction with propofol in calves based on clinical and physiological parameters and to find a more reliable strategy for general anaesthesia in ruminants.Materials, Methods & Results: The research was carried out on 30 calves, from new-born up to 3-months-old, undergoing surgery operation. Each group consisted of 15 animals that were divided as isoflurane and sevoflurane. For premedication, atropine was administered at a dose of 0.04 mg/kgvia subcutaneous injection in calves. For induction, 15 min after atropine application, propofol was given at 5-6 mg/kgvia intravenous infusion. Then, endotracheal intubation was performed and inhalation anaesthesia began at 5 min after induction. In the isoflurane group, the onset of anaesthesia concentration was set to 3-5% and the maintenance was set to a concentration of 1.5-3%. In the sevoflurane group, the onset of anaesthesia concentration was set to 5-7% and the maintenance was set to a concentration of 2.5-4%. To monitor the calves, the heart rate (HR), the pulse rate (PR), the systolic blood pressure (SBP), diastolic blood pressure (DBP), the respiratory rate (RR), the rectal temperature (RT) and the electrocardiogram (ECG) measurements were recorded before anaesthesia, the premedication, the induction periods, at 5, 15, 30, 45, 60, and 75 min after the onset of inhalation anaesthesia during the operation period. Blood samples were taken before anaesthesia, premedication, induction periods, at 30 and 75 min during the operation and the red blood cell (RBC) count, white blood cell (WBC) count, the amount of haemoglobin (HGB), the haematocrit concentration (HCT), and the platelet (PLT) count were evaluated. Based on the findings, isoflurane and sevoflurane suppressed the cardiovascular system minimally. Both anaesthetic agents caused decreases that did not exceed the physiological limits compared to the measurements taken before the initiation of anaesthesia. Although no significant differences were detected between the groups (P > 0.05) at clinical parameters, the RT differences were regarded as statistically significant according to the measurements that were taken before anaesthesia at all measurement times (P < 0.05). In both groups, the changes that occurred in the P wave, the PR interval, and in the QRS, R and T waves remained within the reference values given in the literature. Both anaesthetic agents have similar effects on the ECG. The dramatic no changes throughout anaesthesia in terms of the amount of HGB and HCT, the RBC, the WBC, and the PLT were not statistically significant, which may be associated with good tissue perfusion.Discussion: Since no serious complications occurred with either anaesthetic option, we have concluded that isoflurane and sevoflurane have similar effects on the cardiopulmonary systems of calves. In addition, the effects of propofol, which is used for induction, have been evaluated and observed and this drug is an effective and reliable option to initiate inhalation anaesthesia. The research on the use of this anaesthetic in calves is limited and most of the existing studies investigated its combination with injectable anaesthetics. As a result, in this research, we concluded that isoflurane and sevoflurane induce similar physiological measurement results, blood parameters, and ECG results and that both anaesthetics cause minimal complications.

Background: Disbudding is often practiced in modern farm because of the reasons for the safekeeping of the animal, other animals lessen the risk of injury and less aggressive behavior. Without regard to the method of disbudding leads to disruption behavioral changes, cardiac and endocrine responses related pain of animals. Sedation, local anesthesia and analgesia are performed studies in order to eliminate of cardiac, endocrine, behavioral response which is caused by pain associated with disbudding. In this study, it was aimed to determine the effect on the oxidant and antioxidant system in the calves of disbudding by using the caustic paste with and without painkiller.Materials, Methods & Results: The animal material of the study was created 24 Simmentals calves in different sexes on average 2 weeks (± 2 days) and 50 kg (± 15 kg) live weight. The cases were randomly divided into 2 groups of 12 calves in each group. In the group I (analgesia group); caustic paste+painkiller (2.2 mg-1 flunixin meglumine intravenous, IV) and group II (non-analgesia group); as disbudding applied with caustic pasta application only were divided into 2 groups. In the I group, 15th min before the application, flunixin meglumine at a dose of 2.2 mg-1 was administered IV and the horn blunting was performed by caustic paste method. Blood samples were taken at 15, 30 and 60th min after completion of horn blunting and physiological findings were recorded. In group II, the horns of the calves were disbudding with the same technique (but no analgesia aplication). Blood samples were taken at 15, 30 and 60th min after completion of horn blunting and physiological findings were record. Cortisol, glucose, total oxidant capacity (TOC) and total antioxidant capacity (TAC), 8-hydroxy-2’-deoxyguanosine (8-OHdG), glutathione (GSH), superoxide dismutase (SOD) enzymes measurements (ELISA) were performed in both groups. TOC and TAC tests were used to determine the oxidative stress index in the obtained serum, 8-OHdG measurement which is the most sensitive and most frequent oxidative DNA damage indicator for determination of oxidative damage; GSH, SOD enzymes were analyzed by ELISA using commercial kit for the evaluation of antioxidant potential. For evaluation of pain in animals, cortisol (ELISA) and glucose level in serum were measured with ELISA by using commercial kit. In the group without flunixin meglumine, cortisol was increased significantly from the 15th min (P < 0.05), but there was no increase in the 30 and 60th min in painkiller administered group. Glucose levels were higher in the group not using painkillers than those used at 15th (P < 0.001) and 30, 60th min (P < 0.05). TOC (P < 0.001) and 8-OHdG (P < 0.05) values were significantly higher in the group without painkiller while TAC, GSH and SOD levels (P < 0.05) were significantly decreased.Discussion: It has been observed that sedation (such as xylazine) and local anesthesia (such as lidocaine) use removed pain-induced stress in the disbudding with caustic paste in calves. However, in order to remove the endocrine response, it is necessary to combine the anesthesia protocol with the analgesic (such as flunixin meglumine) combination. According to our results concluded that the painkiller given before the disbudding process was supporting the antioxidant system, reducing the level of cortisol and oxidative stress.

In this study, we investigated whether jervine (J) could prevent gastrointestinal (GI) side effects of abdominopelvic radiotherapy (RT) in Wistar-Albino female rats. Rats were divided into five groups: control (C), J only (J), J administered at 5 mg/kg/days for 7 days, RT only (RT), J before RT (J þ RT), J administered for seven days before RT, J both before and after RT (J þ RT þ J), and J administered for 7 days before RT and after RT for 3 days. The weights of rats were measured on the 1st, 7th, and 10th days of the study. Rats were sacrificed to obtain tissues from the liver and intestine, which was followed by taking blood samples intracardially. In addition, the tissues were stained with pyruvate dehydrogenase (PDH) immunohistochemically. In our study, J supplementation markedly reduced weight loss, and histopathological, immunohistochemical, biochemical results suggest that J had a protective effect on GI toxicity following RT.
