This study evaluated whether anesthesia with essential oil (EO) of Lippia alba (300 mg L?1 for 4 min) prior to electronarcosis (128 V m?1 × 300 Hz for 5 s) or hypothermia (ice/water slurry) could delay fish spoilage during chilled storage of whole fish. Silver catfish (Rhamdia quelen) were subjected to two different pre-stunning treatments (water or anesthesia with EO of L. alba) followed by two different stunning procedures (hypothermia or electrical stunning), yielding four groups (n = 32/group): water (control) + hypothermia, water (control) + electrical stunning, EO of L. alba + hypothermia, and EO of L. alba + electrical stunning. After stunning, fish were slaughtered by percussion and stored in ice. Preslaughter anesthesia with the EO of L. alba extended fish shelf life by delaying the loss of freshness (nucleotide degradation), growth of Enterobacteriaceae, and fish deterioration (sensory evaluation). Such preservative effect was most remarkable for fish that were subsequently submitted to electrical stunning, as they had the lowest demerit scores and greatest shelf life in the sensory evaluation. Our results showed that preslaughter anesthesia with EO of L. alba followed by electrical stunning can delay the loss of freshness and extend fish shelf life during chilled storage. 相似文献

Six cases of mandibular fractures associated with severe periodontal disease that had been treated by mandibulectomy, due to intense bone loss, were evaluated retrospectively. The dogs were mainly older, small breed dogs that had suffered a traumatic event. Four dogs had a bilateral mandibulectomy and 2 a unilateral mandibulectomy. 相似文献

This study examined ammonia, urea, creatinine, protein, nitrite, nitrate, and phosphorus (P) excretion at different water hardness, humic acid, or pH levels in silver catfish (Rhamdia quelen) juveniles. The fish were exposed to different levels of water hardness (4, 24, 50, or 100 mg L?1 CaCO3), humic acid (0, 2.5, or 5.0 mg L?1), or pH (5.0, 6.0, 7.0, 8.0, or 9.0) for 10 days. The overall measured nitrogen excretions were 88.1 % (244–423 μmol kg?1 h?1) for ammonia, 10.9 % (30–52 μmol kg?1 h?1) for creatinine, 0.02 % (0.05–0.08 μmol kg?1 h?1) for protein, 0.001 % (0.002–0.004 μmol kg?1 h?1) for urea, 0.5 % (0.64–3.6 μmol kg?1 h?1) for nitrite, and 0.5 % (0.0–6.9 μmol kg?1 h?1) for nitrate, and these proportions were not affected by water hardness or humic acid levels. The overall P excretion in R. quelen was 0.14–2.97 μmol kg?1 h?1. Ammonia excretion in R. quelen usually was significantly higher in the first 12 h after feeding, and no clear effect of water hardness, humic acid levels, and pH on this daily pattern of ammonia excretion could be observed. Water hardness only affected the ammonia and P excretion of R. quelen juveniles in the initial and fifth days after transfer, respectively. The exposure of this species to humic acid increased ammonia excretion after 10 days of exposure but did not affect P excretion. An increase in pH decreased ammonia and increased creatinine excretion but did not change P excretion in R. quelen. Therefore, when there is any change on humic acid levels or pH in the culture of this species, nitrogenous compounds must be monitored because their excretion rates are variable. On the other hand, P excretion rates determined in the present study are applicable to a wide range of fish culture conditions. 相似文献

An early event correlated with the gene-for-gene hypersensitive response (HR) is the accumulation of active oxygen species (AOS), also known as the oxidative burst. We present data that genetically demonstrates that the oxidative burst is a downstream component of the RPS2- avrRpt2gene-for-gene signal cascade. An in planta AOS assay using the fluorescent probe 2′,7′-dichlorodihydrofluorescein diacetate (DCFH-DA) was modified for use with the Arabidopsis thaliana / Pseudomonas syringae pv.tomato (P. syringae pv. tomato) model system. An oxidative burst occurred between 8 and 15 hpi with avirulent P. syringae pv. tomato(avrRpt2), but not with virulent P. syringae pv. tomato. This burst preceded cell death and was not observed in the RPS2 Arabidopsis mutantsrps2-101C and rps2-201 inoculated with avirulent P. syringae pv. tomato. An HR-like response has been observed when plants undergoing a systemic acquired resistance (SAR) response are challenged with a normally virulent pathogen (manifestation stage of SAR), however an HR-like oxidative burst was not detected by the in planta AOS assay during this stage of SAR. 相似文献

Behavioral responses, blood markers, and fillet properties were investigated after silver catfish exposure to different electric field strengths, frequency, and duration of electric current in the preslaughter stunning. All combinations of electric fields and frequencies were able to stun fish. Longer apparent stun was obtained at the intermediate electrical frequencies. High electric field strength detracted the texture of fillets. At least 5 s was required to stun fish, and longer exposure to electrical current did not prolong the apparent stun or damage fillet properties. Results indicate that silver catfish are relatively resistant to electronarcosis. 相似文献

Cristiane Maria Fernandes de Melo Jaqueline Bianque de Oliveira Ana Célia Rodrigues Athayde Ant?nio Flávio Medeiros Dantas Thais Ferreira Feitosa Vinícius Longo Ribeiro Vilela Danilo José Ayres de Menezes Paulo Guilherme Carniel Wagner 《Veterinary research communications》2012,36(4):235-238
Studies on the parasitic fauna of migratory sea birds of the Puffinus genus are scarce. Therefore, the aim of this study was to identify parasites of 16 specimens of Puffinus puffinus (Procellariiformes, Procellariidae) that died during the period of June 2011 to December 2011 at the Wildlife Screening Center (CETAS) of the Brazilian Institute of Environment and Natural Resources (IBAMA) in Cabedelo, Paraíba. During necropsy, biting lice and/or gastrointestinal helminths were collected in seven (43.7?%) birds. Lice were collected in five (31.2?%) birds, and the species identified were Halipeurus diversus, Trabeculus aviator, Austromenopon paululum), Saemundssonia sp. and Naubates sp. The prevalence of helminths was also 31.2?%. The nematodes species were Seuratia shipleyi and Contracaecum sp., and cestodes were Tetrabothrius sp. This is the first record in Brazil of Naubates sp., Seuratia shipleyi, Contracaecum sp., and Tetrabothrius sp. in Puffinus puffinus. 相似文献
