Abstract: Due to the negative environmental effects of herbicides, restrictions are imposed in many developed countries and the transition to alternative methods is encouraged. Upon these restrictions and prohibitions, non-chemical weed control methods have been started to be developed. One of these alternative weed control methods is the electric current method. Background: Using multiple electrodes, the mortality rates were measured by exposing the plants germinated in laboratory conditions to AC and DC currents for different periods. Objective: In this study, the effects of direct current (DC) and alternating current (AC) on the mortality rates of plants were investigated. Methods: By comparing the NDVI (normalized difference vegetation index) values measured before and 1 week after the plants were exposed to electrical current, the effect of AC/DC on the mortality rate was determined. Results: While mortality was between 11% and 17% for AC, mortality occurred at a rate of 31% in plants that had 300 volts DC applied for 350 s. Conclusions: The degrees (r) of these relationships were 79.7% and 95.7%, respectively. According to these results, mortality rates increased as the voltage increased.

Abstract Purpose: The effect of a prophylactic oleuropein-rich diet before anesthesia accompanied by the widely-used steroid-based neuromuscular drug rocuronium on mast cell activation was investigated in the study. Methods: 14 rabbits used in the study. The rabbits in the oleuropein group were given oleuropein-rich extract added to the animals’ water at doses of 20 mg/kg oleuropein for 15 days orally. After 15 days, all rabbits in the two groups were given general anesthesia with rocuronium of 1 mg/kg. After 1 day, animals were sacrificed and the liver tissue sections stained with H&E, toluidine blue and tryptase for immunohistochemical study. Results: There was no statistically significant difference between ALT, AST and albumin averages of the oleuropein and control groups (p> 0.05). The tryptase average of the control group was higher than the tryptase average of the oleuropein group and this difference was statistically significant (p=0.003). The T. blue average in the oleuropein group was higher than the control group. However, there was no statistically significant difference between groups (p=0.482). Conclusions: Rocuronium adverse effects, like hypersensitivity and anaphylaxis, may limit routine use of this substance. The use of oleuropein reduced the number of inflammatory cells and prevented degranulation.

ABSTRACT The objective of this study was to determine the effects of raw bee propolis and water or ethanol extract of propolis on growth performance, some blood parameters, and immunoglobulins in 15-20-week-old Ross-308 broiler breeders. The birds in the control were fed a diet without propolis, whereas the birds in the treatment groups were fed diets with raw propolis (RP), water (WEP), and ethanol (EEP) extract of propolis at the level of 1200, 400, and 400 ppm, respectively. Raw propolis and propolis extracts did not affect body weight gain, feed intake, feed conversion ratio, and some blood parameters, such as aspartate aminotransferase, alanine aminotransferase, total antioxidant status, triglyceride, and phosphorus. Birds fed EEP and those in control group had a lower IgA value compared with birds fed RP. Birds fed RP had higher IgM level than those of the other groups, and birds fed EEP had lower IgM level than those of control and RP-fed group. The IgY value of breeders fed EEP was higher than those of the other treatment birds, whereas that of WEP-fed birds was higher than those of control and RP treatment. The antibody levels of Anti-Newcastle disease virus and anti-infectious bursal disease virus were higher in EEP and RP-fed groups than those in the control and WEP-fed groups. The WEP decreased total oxidant status value compared with the control and RP treatments, whereas EEP and WEP increased plasma total protein and calcium contents compared with the control. The EEP increased plasma albumin content compared with RP. The addition of propolis extracts, especially WEP and EEP, to diet improves immunity and antioxidant activity, as well as enhances Ca absorption of broiler breeders.

ABSTRACT PURPOSE: To investigate the effects of preoperative rectal ozone insufflation on surgical wound healing over the proinflammatory cytokines and histopathological changes. METHODS: Twenty one rabbits were divided into 3 groups. Sham, surgical wound, and ozone applied (6 sessions, every other day 70 µg/mL in 12 mL O2-O3 mixture rectally) surgical wound groups were created. TNF-alpha and IL-6 levels from all rabbits were studied at the basal, 24th hour, and 72nd hour. The histopathological examination was done by removing the surgical scar tissue at the end of 72nd hour. RESULTS: TNF-alfa and IL-6 levels were significantly lower compared to the control group, in the rabbits treated with ozone. The increase in angiogenesis, the decrease in the number of inflammatory cells, epidermal and dermal regeneration, better collagen deposition, and increased keratinisation in stratum corneum were observed in the histopathological examination. It was determined that the wound healing noticeably accelerated in the ozone group. CONCLUSION: Preoperative rectal ozone insufflation had a positive effect on surgical wound healing in acute period.

RESUMOJUSTIFICATIVA E OBJETIVOS: Tenoxicam é amplamente usado no tratamento da osteoartrite (OA)e o nosso objetivo foi comparar a eficácia de tenoxicam administrado por via oral (VO) e intra-articular (IA) no tratamento da OA.MÉTODOS: Este estudo foi conduzido entre 2011 e 2012 por meio de análise retrospectiva ecomparação dos resultados de 60 pacientes que foram clínica e radiologicamente diagnosticadoscom OA degenerativa de joelhos na Policlínica de Tratamento da Dor do Hospital Estadual deBünyan. Os 60 pacientes incluídos no estudo foram alocados em dois grupos. O primeiro grupo(tenoxicam IA, n = 30) incluiu resultados de pacientes submetidos à injeção nos joelhos porvia IA de 20 mg de tenoxicam uma vez por semana durante três semanas e o segundo grupo(tenoxicam VO, n = 30) incluiu pacientes que receberam 20 mg de tenoxicam por VO uma vezpor dia durante três semanas. Todos os pacientes foram avaliados clinicamente na fase basalpré-tratamento e em uma semana, um mês e três meses pós-tratamento, de acordo com oscritérios especificados.RESULTADOS E CONCLUSÕES: Dos 60 pacientes, 22 eram do sexo masculino e 38 do sexo feminino.Em ambos os grupos, melhorias significativas foram detectadas em todos os parâmetros da escalavisual analógica, do índice Western Ontario and MacMaster (Womac --- dor, atividade física erigidez dos joelhos) e do índice de Lequesne nas avaliações feitas em uma semana, um mês etrês meses e comparadas aos valores basais. Além disso, uma melhor adesão ao tratamento etolerabilidade ao sistema gastrointestinal no grupo tenoxicam IA também foram observadas. Aadministração de tenoxicam IA pode ser considerada como um método opcional de tratamentoem pacientes com OA de joelhos que não podem usar tenoxicam por VO, especialmente porcausa dos efeitos colaterais sobre o sistema gastrintestinal, e naqueles com dificuldades de adaptação ao tratamento.

ABSTRACTBACKGROUND AND OBJECTIVES:Tenoxicam is widely used in osteoarthritis treatment and we aimedto compare the effectivity of oral and intra-articular administration of tenoxicam in osteoarthri-tis treatment.METHODS: This study was performed between 2011 and 2012 by retrospectively analyzing andcomparing the findings of 60 patients who were clinically and radiologically diagnosed with kneedegenerative osteoarthritis in Bünyan state hospital pain policlinic. 60 patients included in thestudy were divided into two groups. The first group (tenoxicam IA, n = 30) included patientfindings of those subjected to intra-articular injection of 20 mg tenoxicam to the knee oncea week for three weeks and the second group (oral tenoxicam, n = 30) included patients whowere administered 20 mg oral tenoxicam once a day for three weeks. All patients were clini-cally evaluated pre-treatment and in the 1st week, 1st month and 3rd month post-treatmentaccording to specified criteria.RESULTS AND CONCLUSIONS: Twenty two of 60 patients included in the study were male and 38were female. In both groups significant improvements were detected in all of the observedparameters: visual analog scale, Western Ontario McMaster Osteoarthritis Index (pain, physicalactivity, knee stiffness) and Lequesne index scores and in the evaluations performed in 1st week,1st month and 3rd month with respect to pre-treatment values. Besides, a better complianceto treatment and gastrointestinal system tolerability in tenoxicam IA group was also observed.Intra-articular tenoxicam administration could be thought as an alternative treatment methodin patients with knee osteoarthritis who cannot use oral tenoxicam especially due to systemicgastrointestinal system side effects and those who have difficulties in adapting to treatment.

PURPOSE:To evaluate the applicability and airway management capacity of v-gel(r) and Cobra PLA in rabbit anaesthesia during assisted (AV) or controlled ventilation (CV).METHODS:This study was carried out in 44 adult New Zealand white rabbit. Baseline arterial pH, PaCO2 and PaO2 values were recorded. Anaesthesia was induced with 5 mg/kg xylasine and 35 mg/kg ketamine HCI combination. AV rabbits were assigned as; control (CG-AV; n=5), LMA (LMA-AV; n=5), cobra PLA (PLA-AV; n=5) and v-gel (v-gelAV; n=5). Rabbits have CV were also assigned as; ET (ET-CV; n=6), LMA (LMA-CV; n=6), cobraPLA (PLA-CV; n=6) and v-gel (v-gelCV; n=6). All measurements were repeated 1st, 5th, 15th and 30th mins during anaesthesia.RESULTS: The less insertion time, number of attempt and complications are recorded in v-gel applied rabbits compared to other apparatus. For arterial pH values significant differences are recorded in especially at 15th and 30th min between groups of CV (p<0.005 or p<0.001). All groups had similar results with each other during anaesthesia for PaCO2 except for LMA-CV group.CONCLUSION:The v-gel may be used as airway device in rabbit anaesthesia undergoing AV or CV and also can be a suitable alternative to endotracheal tubes and laryngeal mask airway.
