Propose: To compare the postoperative analgesic effects of electroacupuncture, morphine or sham acupuncture in dogs undergoing mastectomy. Methods: Thirty client-owed dogs undergoing to mastectomy were randomly assigned to three groups of 10 animals each and received either morphine (T-M), the electroacupuncture (T-EA) or sham procedure (T-Sham). Pre-anesthetic medication was acepromazine (0.05 mg kg-1, IM). Anesthesia was induced with propofol (4 to 5 mg kg-1, IV) and maintained with isoflurane. Postoperatively pain degree was assessed using a numerical rating scale. Dogs were scored at 1, 3, 6 and 12 hours post-extubation. If the pain score was ≥6, supplemental morphine was administered. Serum cortisol concentration was measured before pre-anesthetic medication, at 45 minutes after the anesthetic induction, and at 1, 3 and 6 hours post-extubation. Result s: The pain score did not differ among the treatments, but rescue analgesia was lower in the T-EA group (2 of 10 dogs), when compared with T-Sham (6 of 10 dogs) and T-M (6 of 10 dogs) groups. Serum cortisol concentration did not differ among the treatments. Conclusion: Electroacupuncture reduces the postoperative analgesic requirement and promotes satisfactory analgesia in dogs undergoing mastectomy.


Purpose: To compare the postoperative analgesic effects of the extradural tramadol or morphine in female dogs undergoing ovariohysterectomy. Methods: Sixteen female dogs were randomly assigned to two groups of eight animals each and received morphine (0.1mg kg-1 M group) or tramadol (2mg kg-1 T group). The pre-anesthetic medication was intravenously (iv) acepromazine (0.05mg kg-1). Anesthesia was induced with propofol (4mg kg-1iv) and maintained with isofurane. The degree of analgesia was evaluated using a numerical rating scale that included physiologic and behavior variables. Dogs were scored at one, three, six and 12 hours after surgery by one blinded observer. Dogs were treated with morphine (0.5mg kg-1) if their scores were >6. Serum cortisol was measured before the pre-anesthetic medication was administered (basal), at the time of the ovarian pedicle clamping (T0), and at 1 (T1), 6 (T6) and 12 (T12) hours postoperative. Results: The pain score did not differ between morphine and tramadol treatments. Rescue analgesia was administered to one dog in the T treatment group. Serum cortisol did not differ between treatments. Conclusion: The extradural administration of morphine or tramadol is a safe and effective method of inducing analgesia in female dogs undergoing ovariohyterectomy.

To evaluate the potential of heterologous platelet-rich plasma (PRP) gel for surgical skin wound healing in rabbits.Blood from a single healthy dog was used for PRP production, with calcium gluconate added to the PRP to form the gel. Two surgical excisions, one to the right and the other to the left of the dorsal midline, were made in six rabbits. One side was randomly allocated to topical application of a physiological solution, and the other was allocated to treatment with heterologous PRP gel. Clinical assessments (weight, pain sensitivity, coloring, edema, hyperemia, exudation, crust, and granulation) and morphometric evaluations were performed 0, 3, 7, 10, 14, and 17 days postoperatively. Histological analysis was performed on the 17th day.With the exception of the presence of a crust at day 10, clinical variables did not differ significantly between the experimental groups. In both the control and PRP-treated groups, differences were identified when comparing time-points in terms of wound area reduction. Histological results indicated no significant differences between the control group and the PRP-treated group.Heterologous platelet-rich plasma gel promoted dermal wound healing in rabbits with no adverse effects.

Effective seed storage methods for orchid species provide a unique opportunity to preserve large amounts of germplasm. Early evaluation of the physiological status of seeds is useful for selecting seed lots for conservation. To score seed quality, seeds from nine Cattleya species (Cattleya granulosa, Cattleya hegeriana, Cattleya intermedia, Cattleya mossiae, Cattleya purpurata, Cattleya sanguiloba, Cattleya tenuis, Cattleya tigrina and Cattleya walkeriana) were germinated on Knudson C medium and viability was measured using a tetrazolium (TZ) test following pre-conditioning in a 10% sucrose solution, both before and after storage at -18°C for 3 mo. Tetrazolium test results were quantified using digital imaging of germinating seeds on a flatbed scanner. Seed viability (with or without pre-conditioning in sucrose), germination, Germination Velocity Index (GVI) and the correlation between viability measurements and germination were also evaluated. Both the tetrazolium test and the germination results showed that there was no loss of viability after storage, although in five seed lots, the GVI decreased. Pre-conditioning improved the correlation between viability exhibited in the tetrazolium test and seed germination. Image analysis proved to be a powerful tool for analysing these small seeds. © 2011 The Society for In Vitro Biology.

Macadamia is one of the most valuable commercial nuts and its culture is a good alternative for small farmers or for large properties with a low capacity for the mechanization of its areas. Macadamia clones, due to their morphological proximity exhibited some difficulties in field identification that could difficult the right plant distribution. The objective of this work was to genetically characterize, by RAPD markers, different macadamia clones under cultivation. Leaves from 'HAES-741', 'HAES-660', 'IAC-920BX', 'IAC-920', 'HAES-344', 'IAC-420', 'HAES-816', 'IAC-1.21', 'Shimada', 'IAC - Campinas B', 'IAC - Campinas A' and 'HAES-Aloha' were donated by Queen Nut Macadâmia. DNA was extracted and amplified with 15 primers and the binary data (presence/absence of bands) collected was used and dendrograms constructed. Clone identification, via RAPD was possible using primers Op G18, C19 and C7. Most of the genetic variation is inside the Brazilian or Hawaiian groups rather than between the groups and could allow inbreeding or crossing between distant clones.


Disruptions in sperm production include decreased sperm motility and increased of abnormal sperm. Seminal plasma appears to exert important effects on sperm function. The objective was to evaluate the dry and rainy season influence on the seminal characteristics and semen plasma proteins. Eleven bulls with ages ranging from 34 to 38 months were submitted each one to 12 semen collect with eletroejaculation 6 on dry season and 6 on rainy season with 14 days interval, totalizing 144 samples. Qualitative and quantitative semen characteristics were evaluated. Samples of semen were centrifuged (1.500 g / 15 minutes) and conditioned and stored (-20°C) until further processing. The proteins were extracted and quantified to electrophoresis performed. Variance analysis and Tukey test 5% was used. The semen vigor (P < 0.01), minor defects and total defects (P < 0.05) showed statistical difference between seasons, while the volume, motility and minor defects did not (P > 0.05). The number of bands occurred between 6 and 125 kDa. The molecular band of 26 kDa was present in 100% of bulls in rainy season. The molecular bands of 6, 9 and 125 kDa showed a high frequency in dry and rainy season. In conclusion, these results showed a band distribution variation throughout the season and the year seasons changed the semen quality with increase sperm vigor and reduction of abnormal sperm on dry season.

Heart failure (HF) is characterized by a reduced tolerance to exercise due to early fatigue and dyspnea; this may be due in part to skeletal muscle myopathy with a shift from slow to fast fibers and loss of muscle mass. Muscle wasting does not occur similarly in all types of muscle fiber, thus we tested the hypothesis that HF induces skeletal muscle atrophy in a fiber type-specific manner altering the expression of atrogin-1 and MuRF1 in a fast muscle of rats with monocrotaline-induced heart failure. We studied extensor digitorum longus (EDL) muscle from both HF and control Wistar rats. Atrogin-1 and MuRF1 mRNA content were determined using Real-Time RT-qPCR while muscle fiber cross-sectional area (CSA) from sections stained histochemically for myofibrillar ATPase were used as an index of type-specific fiber atrophy. The measurement of gene expression by RT-qPCR revealed that EDL muscle mRNA expression of MuRF1 and atrogin-1 was significantly increased in the HF group. Muscle fiber type IIB CSA decreased in the HF group compared to the CT group; there was no significant difference in muscle fiber types I and IIA/D CSA between the HF and CT groups. In conclusion, we showed that HF induces fiber type IIB specific atrophy, up-regulating atrogin-1 and MuRF1 mRNA expression in EDL muscle of monocrotaline treated rats. © 2010 Springer Science+Business Media B.V.

The study had the objective to evaluate the effect of the fertilization with filter cake enriched with soluble phosphate on the sugar yield. The experiment carried at Presidente Prudente-SP, used a randomized complete block design, in the factorial scheme 5 × 4, where the first factor consisted of doses of filter cake (0; 0.5; 1.0; 2.0 and 4.0 t ha-1) and the second, doses of phosphorus fertilizer (0, 50, 100, 200 kg ha-1 of P2O5), with 4 replicates, totaling 80 plots. The results indicated that phosphorus applied in planting furrows improves the quality of sugarcane raw matter by increasing the levels of soluble solids, total reducing sugars and sucrose in the stalks. The phosphorus also increases the productivity of sugar. The filter cake applied in planting furrow has the potential to partially replace the chemical fertilization with phosphate aiming to improve the quality and the productivity of sugar. The best combination was filter cake at dose between 2.6 and 2.7 t ha-1 combined with dose between 160 and 190 kg P2O5 ha-1 for obtaining best response of soluble solids and productivity of sugar.


A study was conducted to investigate whether the rhizosphere of pastures promotes root colonization by rhizobacteria of the Bacillus genus, as also the fertility of this soil interferes with bacterial colonization. For this we collected samples of the root system of B. decumbens, B. brizantha and Panicum maximum in 18 farms with cattle ranching in western Sao Paulo, Brazil. While driving to work were effective analysis of soil fertility in the sampled areas. Quantification of Bacillus spp. In the rhizosphere of plants was performed by employing the technique of thermal shock and dilution ending with plating on culture media. Colonization of Bacillus in the rhizosphere of pasture were considered low and there was no correlation between rhizosphere colonization with most of the parameters of soil fertility. Just organic matter in the soil correlated negatively with bacterial colonization in the rhizosphere. No significant difference was found in the colonization of Bacillus in the rhizosphere of three grassland species assessed.

The fuzzy logic admits infinite intermediate logical values between false and true. With this principle, it developed in this study a system based on fuzzy rules, which indicates the body mass index of ruminant animals in order to obtain the best time to slaughter. The controller developed has as input the variables weight and height, and as output a new body mass index, called Fuzzy Body Mass Index (Fuzzy BMI), which may serve as a detection system at the time of livestock slaughtering, comparing one another by the linguistic variables "Very Low", "Low", "Average ", "High" and "Very High". For demonstrating the use application of this fuzzy system, an analysis was made with 147 Nellore beeves to determine Fuzzy BMI values for each animal and indicate the location of body mass of any herd. The performance validation of the system was based on a statistical analysis using the Pearson correlation coefficient of 0.923, representing a high positive correlation, indicating that the proposed method is appropriate. Thus, this method allows the evaluation of the herd comparing each animal within the group, thus providing a quantitative method of farmer decision. It was concluded that this study established a computational method based on fuzzy logic that mimics part of human reasoning and interprets the body mass index of any bovine species and in any region of the country.
