Análise de sobrevivência aplicada ao desenvolvimento do pulgão Aphis gossypii Glover, 1877 (Hemiptera: Aphididae) em plantas de pepino (Cucumis sativus L.) contaminadas com fungicidas

It was aimed to evaluate the influence of fungicides utilized in cucumber on the development of the aphid Aphis gossypii Glover under greenhouse conditions. The experimental design was completely randomized with four treatments and 45 replicates, being each plot consisting of a first instar nymph coming from an apterous female in early reproductive period. The fungicides utilized and their respective dosages at g i.a.L(-1) were 800 PM sulphur (1.6), 800 PM mancozeb (1.6) and 840 PM copper oxichloride (1.5). The control was made up of water only. The products did not influence the median time of life in each instar and the nymphal stage, being respectively 1 and 4 days. Copper oxychloride and mancozeb increased the median time of life in days and the total life cycle of the adult stage of this species.

Study on functional cardiorespiratory changes after laparoscopic Nissen fundoplication

PURPOSE: To analyze the behavior of cardiopulmonary function in postoperative of laparoscopic Nissen fundoplication.METHODS: Thirty-two patients, 13 males (41%) and 19 females (59%), were evaluated. Their age ranged from 25 to 67 years, with a mean of 44.4 +/- 10.9. Pulmonary volumes, respiratory pressures and exercise tests were performed in the preoperative period (PRE) and in the first (PO1), second (PO2), fifth (PO5) and thirtieth (PO30) postoperative periods.RESULTS: Thirty-two patients were evaluated, of whom 59% were females. Mean age was 44.4 +/- 10.9 years. Lung volumes had significant decrease at PO1 and PO2 and were similar to PRE values at PO5. Respiratory pressures were altered only at PO1. The distance covered in the 6-minute walk test had significant reduction until PO2, and climbing time in the stair-climbing test significantly increased at PO2.CONCLUSION: Patients submitted to LNF surgery have decreased cardiorespiratory function in the early postoperative period; however, they soon return to preoperative conditions.

Situação do aleitamento materno em população assistida pelo programa de saúde da família-PSF

Este estudo objetivou identificar a prevalência dos diferentes tipos de aleitamento e sua relação com variáveis maternas no município de Conchas-SP, totalmente coberto pelo PSF. Foram obtidas informações sobre a alimentação atual das crianças menores de um ano que compareceram à primeira etapa da Campanha de Multivacinação de 2003. As associações foram submetidas ao teste do qui-quadrado, adotando-se 5% como nível de significância estatística. As prevalências do Aleitamento Materno Exclusivo (AME) e do Aleitamento Materno Predominante (AMP), em menores de 4 meses de vida, foram 25,4 e 44,4%, respectivamente, e 66,7% do total de crianças menores de um ano ainda eram amamentadas. A prevalência do AME em menores de 6 meses foi heterogênea, variando de 7,4 a 41,2%, conforme a equipe do PSF de procedência das crianças. Ter passado por dificuldades no início do aleitamento associou-se a menores prevalências de AME e Aleitamento Materno (AM). Esses resultados evidenciam situação distante da recomendada pela Organização Mundial de Saúde e aquela para a qual há evidências de máximo efeito protetor à saúde infantil, reafirmam a necessidade de apoio às mães no período puerperal precoce e demonstram a importância de diagnósticos desagregados por regiões para o planejamento de ações de promoção ao AM.

Attack on Chestnut-bellied Euphonia nestlings by army ants

I report some observations of a Chestnut-bellied Euphonia (Euphonia pectoralis) nest in a lowland Atlantic Forest of southeastern Brazil during the early nestling period. During 7.5 hours of observations, the nest was attended 46.3% of the time, 45.6% by the female and 0.7% by the male. Unattended periods lasted 16-38 min. Parents visited the nest most of the time together at 36-59 min intervals. There were 1.06 feeding visits per nestling per hour. The two nestlings in the nest ended up preyed upon by army ants (Labidus praedator, Ecitoninae). The low height of the nest (0.8 m) may have facilitated its detection by the ants.

Laparoscopic adhesiolysis in a mini pony

Background: Intraperitoneal adhesions are common in equines, especially following exploratory celiotomy. Adhesiolysis is the treatment of choice for patients presenting postsurgical adhesions. Laparoscopic approach for adhesiolysis presents several advantageous aspects in human patients. The aim of the current study was to report a case of successful laparoscopic adhesiolysis in a mini pony horse. Case: A male Shetland Pony, weighing 140 kg, was admitted under complaint of right hind limb trauma and treated surgically for metatarsal fracture reduction. The patient has also had intermittent episodes of colic and was always treated clinically without major complications. The pony had no history of previous abdominal surgery and no episodes of acute abdomen were seen during hospital stay. Three months following ostheosynthesis, an exploratory laparoscopic approach was carried out to assess the possible cause or consequences of the episodes of acute abdomen. The patient was submitted to general anesthesia, positioned in dorsal recumbency and the abdomen was clipped and aseptically prepared for surgery. During the laparoscopic inspection, there were adhesions involving the ventral abdominal wall and a ventral mesogastric segment of duodenum. Laparoscopic adhesiolysis was performed using a two-port approach, by gently breaking the adhesion bands using meticulous traction with a 10-mm laparoscopic atraumatic Babcock forceps. Afterwards, the intestinal loop was rinsed with heparin sodium solution diluted in normal saline. The pneumoperitoneum was completely drained and the trocars sequentially withdrawn from the abdominal wall. The synthesis of the muscular layer was carried out using an interrupted cross mattress pattern, followed by synthesis of the skin with an interrupted cushion pattern. Total surgical time was 58 min. the patient was able to recover without complications. In the early postoperative period, the surgical recovery was considered excellent. No apparent adhesion involving the previously affected intestinal loop was found during the ultrasound exam following 15 days of surgery. Furthermore, the surgical wounds had healed completely, with no complications. Discussion: In the current case report, the primary cause of the acute abdomen episodes was not determined since the patient had never undergone abdominal surgery. It was hypothesized that an acute inflammation of the duodenal loop that was involved by the adhesion bands may have triggered the adhesiogenesis. Laparoscopy was efficient and presented a short operative time, due to magnification of image and adequate observation of structures surrounded by adhesion bands. Although the use of Babcock forceps is not usually recommended for adhesiolysis in the current literature, it was both effective in manipulating the bowel and performing the adhesiolysis. The heparin solution diluted in normal saline was effective in preventing the recurrence of new adhesions, which was evidenced by ultrasonography following 15 days. The laparoscopic approach usually minimizes the new formation of adhesions as trauma to the peritoneal surfaces is minimized by the use of delicate instruments, as observed in the current study. In addition, laparoscopy reduces the possibility of contact among the peritoneal surfaces and foreign bodies, such as gauze, glove powder and room air particles. Moreover, it maintains the abdominal surfaces in adequate humidity environment.

Hematologic changes in propofol-anesthetized dogs with or without tramadol administration

Drugs commonly used in anesthesia practice may significantly alter the oxidative state of blood cells. This mechanism could contribute to the immune suppression that occurs transiently in the early postoperative period. Thus, we assessed the effects of continuous rate infusion (CRI) of propofol associated or not with tramadol on hematologic parameters in dogs. Eight adult mongrel dogs were anesthetized on 2 occasions, 15 d apart. Two groups were formed: control group (CG) and tramadol group (GT). Propofol was used for induction (10mg kg-1) followed by a CRI (0.7mg kg-1minute-1). The animals were positioned in lateral recumbency and mechanically ventilated with inspired oxygen fraction of 0.6. In TG, tramadol (2mg kg-1) followed by a CRI (0.5mg kg-1minute-1) was administered in dogs. In the CG the sodium chloride (NaCl) solution at 0.9% was administered followed by its CRI, in the same volume that was used in TG. The measurement was taken before anesthesia induction (Tbasal), 30 minutes after induction (T0) and then at 30-minute intervals (T30 to T60). Red blood cells, hematocrit, hemoblogin concentration and total leukocytes count decreased from T0 in both groups. In TG, lymphocytes count at Tbasal [1.86 (0.82) x103µl-1] was greater than at T0, T30 and T60 [0.96(0.50), 0.92(0.48) and 0.95(0.48) x103µl-1, respectively]. No significant differences were observed for platelets neutrophil, eosinophil, basophil and monocyte count. In dogs, propofol-anesthesia associated or not with tramadol promoted decrease in blood cell count and should be used with caution in immunossupressed patients.

Effect of intermittent feeding on growth in early juveniles of the crayfish Cherax quadricarinatus

Three experiments were conducted with juveniles of the crayfish Cherax quadricarinatus to investigate the effect of intermittent feeding regimes on growth and the ability to tolerate the shortage of food. In experiment 1, stage III juveniles were assigned to one of seven intermittent feeding groups (from FS1: 1 day fed/1 day non-fed to FS7: 7 days fed/7 days non-fed) and two control groups, continuously fed (CF) and continuously starved (CS) animals; this experiment comprised a short-term intermittent feeding period until the first molt, followed by a continuous feeding period. In the experiment 2, stage III juveniles were assigned to one of three intermittent feeding groups (FS2 to FS4) and one control group (CF); it consisted of a prolonged intermittent feeding period, until the end of the experiment In the experiment 3, stage VI and VII juveniles were assigned to one of three intermittent feeding groups (FS2 to FS4) and one control (CF); it also consisted of a prolonged intermittent feeding period. The red claw crayfish juveniles were able to tolerate periods of intermittent feeding and underwent compensatory growth after continuous feed was re-established. The ability of crayfish to tolerate intermittent feeding was influenced by developmental stage and duration of the intermittent feeding period. Stage III juveniles survived, but decreased growth, when subjected to prolonged intermittent feeding. However, they showed full compensatory growth when the intermittent feeding period was short and followed by continuous feeding. on the other hand, stage VI-VII tolerated 60 days of prolonged intermittent feeding without any change in growth and survival. The hepatosomatic index (based on wet weight) values of the treatments and the control were similar, suggesting that intermittent feeding may not be considered a nutritional stress condition. The relative pleon weight (based on wet weight) values of the treatments and control were similar suggesting low use of nutrients from the muscle to increase the chance for survival. The juveniles of C quadricarinatus can tolerate relatively long periods of low food availability and this is an important adaptation for their survival in changing/unpredictable environments and an attribute favorable for the production of the species.
