Seletividade e eficácia de herbicidas inibidores da enzima accase na cultura da mamona

This experiment aimed to evaluate the selectivity and efficacy of ACCase-inhibiting herbicides in castor bean crop, at Paraguacu Paulista, São Paulo, during the 2002/03 agricultural season. The experimental design used was randomized complete blocks, with eleven treatments and four replicates, constituted by the following herbicides and adjuvants: fluazifop-p-butyl 313 g ha(-1)) + Agral (TM) 0.2% v/v); sethoxydim 322 g ha(-1)) + Assist (TM) 0.5% v/v); haloxyfop-methyl 120 g ha(-1)) + Assist (TM) 0.5% v/v); clethodim+ fenoxaprop-p-ethyl 75 g ha(-1)) + Assist (TM) 0.5% v/v); quizalofop-pethyl 125 g ha(-1)) + Assist (TM) 0.5% v/v); clethodim 156 g ha(-1)) + Assist (TM) 0.5% v/v); propaquizafop 175 g ha(-1)) + Assist (TM) 0.5% v/v); tepraloxydim 400 g ha(-1)) + Dash (TM) 0.5% v/v); butroxydim 100 g ha(-1)) + Dash (TM) 0.5% v/v); isoxaflutole 60 g ha(-1)) and weed-free check. At the moment of application, castor bean plants presented 4 to 6 leaves and Cenchrus echinatus, 1 to 5 tillers. AL Guarany 2002 cultivar presented high selectivity to ACCase-inhibiting herbicides, without visible symptoms of phytotoxicity in 14 DAA days after application), except for tepraloxydim, whose symptoms persisted until 21 DAA, and isoxaflutole HPPD inhibiting), which showed injuries in older leaves and significant yield reduction. C. echinatus infestation was efficiently controlled by ACCase-inhibiting herbicides between 14 and 21 DAA (>= 95.0%).

Efeitos de diferentes doses de tenoxicam sobre a medula espinhal e as meninges. Estudo experimental em caes

Background and Objectives. The analgesic actions of nonsteroidal anti-inflammatory drugs (NSAID) result from the inhibition of the peripheral synthesis of prostaglandins. In spite of the emphasis on the peripheral action, several studies have shown the potential central action of such drugs. In rats, NSAID doses insufficient to block pain when systemically administered were effective when intrathecally injected. This effect could be mediated by interaction with descending serotoninergic ways together with neurotransmission modulation of glycine or N-methyl-D-aspartate receptors. Our goal was to study the effect of different tenoxican doses in the histology of dogs spinal cord and meninges. Methods. Thirty two dogs (7 to 17 kg) were randomly distributed in four groups: G1 - Control with distilled water (DW); G2 - 2 mg tenoxican diluted in DW; G3 - 4 mg tenoxican diluted in DW; G4 - 10 mg tenoxican diluted in DW in a constant volume of 1 ml. Anesthesia was induced with etomidate and fentanyl and dural puncture was performed with a 25G spinal needle in interspace L6-7. Animals were observed for 72 hours and subsequently euthanized by electrocution. Lumbar and sacral spinal cord segments were removed for further histologic examination. Results. All animals were clinically normal during the observation period and there has been no histologic alteration of the nervous system and meninges. Conclusions. In our experimental model intrathecal tenoxican doses up to 10 mg have not triggered nervous tissue or meningeal injuries in dogs.

Mortalidade por causas externas no Município de São José do Rio Preto, no período de 1996-1998

Introduction: An epidemiological study of the mortality rates by injuries in São José do Rio Preto, State of São Paulo, Brazil, has been carried out. The period considered is 1996-1998. Objectives: To show injuries mortality rates in São José do Rio Preto-SP in 1996-98. Methods: The study was based on official data from the Mortality Information Service of the Brazilian Ministry of Health, and in a survey based on data from medical forensic examiners (IML). Software Epinfo6.0 and Tabwin was utilized for data analises. Results: The results were compared to values obtained in the literature for the other cities of São Paulo and Brazil. In the case of São José do Rio Preto, was observed a decrease in the number of deaths associated with external causes in the period, but particularly in deaths due to traffic accidents with motor vehicles an increase in cases of pedestrians killed by hit-and-run drivers, that is much larger than the corresponding values for Brazil and for the State of São Paulo. The study showed increase in rates of homicides, mainly in the 15 to 39 years age group. Conclusion: This result suggests that is important to start programs to reduce the number of deaths by injuries, as well as the necessity of monitoring locally all these data.

Orbitoethmoidal impacted injury by kitchen knife causing abducens nerve palsy

Introduction: Impacted knife injuries in the maxillofacial region are rare and infrequently reported. In cases of injury involving orbit or eye, these reports are even rarer. Discussion: Damage to the orbital contents may result in a rupture of the globe, extraocular muscle injury, lacrimal gland damage, and others. Orbital foreign bodies are not only difficult to detect, and clinical features vary according to its size, characteristics, shape, penetrating method, and site. In this report, a case of abducens nerve palsy after orbitoethmoidal knife injury is presented. © 2010 Springer-Verlag.

Caracterização de agravos causados por cães e gatos a seres humanos no município de jaboticabal, são paulo, durante o período de 2000 A 2009

The lack of proper control of dogs and cats population and irresponsible pet ownership are factors that favor animal attack and pose serious public health concern. The aim of the present study was to characterize the injuries caused by dogs and cats to humans in the municipality of Jaboticabal, between the years 2000 and 2009, with a view to demonstrate the importance of aggression control in reducing both the risk for rabies transmission and the number of post exposure prophylaxis administration. A retrospective and descriptive study was conducted. 3,972 out of 4,149 records of patients who sought the public health service after being attacked by an animal were analyzed. Dogs were the species that most caused injuries. In the moment of the attack, the doǵs clinical status was declared as healthy in 81.8% of records; and in 81.1% of cases this status were maintained throughout the entire observation period of the aggressor. Most of injuries were characterized by bites in hands or feet, with multiple and superficial wounds. The number of injuries was high, therefore it is crucial to implement strategies to reduce injuries caused by animal attack through health promotion, educational activities and strengthening of integration of public health and veterinary services so that the decision to institute post-exposure prophylaxis is taken with criteria and safety.

Qualidade de mangas cv. palmer após armazenamento sob baixas temperaturas

This study aimed to evaluate the quality of 'Palmer' mangoes previously stored at low temperatures, after their transference to the environmental condition. Fruits harvested at physiological maturity were carefully transported to the Laboratory where they were selected, standardized as the color, size and absence of injuries and treated with fungicide before they were stored at 2°C (75.7% RH), 5°C (73.8% RH) e 12°C (82% RH) for 7, 14 and 21 days. At the end of each period, the fruits were transferred to environmental condition (22.9°C; 62.3% RH), where they were kept for 1, 3, 5 and 7 days, simulating the trading period, and evaluated for the occurrence of injuries and rottenness; peel and pulp color; firmness; contents of soluble solids, titratable acidity and ascorbic acid, as well as, the activities of the enzymes peroxidase, polyphenoloxidase and phenylalanine ammonia-lyase. The results indicated that 'Palmer' mangoes can be stored at 12°C for 21 days without damage to ripening, but with limitations due to the occurrence of decay. The storage at 2°C and 5°C was limited by the occurrence of injuries in the peel, but at the temperature of 2°C these symptoms were more severe and compromised the development of the characteristic color of the peel. However, the ripening of the pulp was not harmed, but this process occurred with less intensity than in mangoes maintained at 12°C.

Encalhes de tubarões anequins e de raias-pretas no litoral do estado de São Paulo, sudeste do Brasil: Relato de casos

Stranding of oceanic-pelagic elasmo branchs in the southeastern Brazil are reported. Data comes from animals observed in the coast of São Paulo state, between 1999 and 2012. Nine individuals of two species were recorded: Pteroplatytrygon violacea (n = 5; mostly during the winter) and Isurus oxyrinchus (n = 4; two in the winter and two in the summer). For P. violacea the strandings restricted to the austral winter suggest that the species follows the intrusion of high temperatures water masses recorded in southeastern Brazil during this season, bringing some individuals to shallow waters. For I. oxyrinchus is possible that individuals escaped from hooks of the commercial pelagic long line fishery and suffered injuries in the esophagus and in the gastric wall, stranding due to difficulties in locomotion and feeding. As these stranded sharks were not necropsied and only two animals were observed during the austral summer, we cannot exclude other causes of beaching such diseases or the intrusion of cold water masses in the continental shelf during this season.
