Abstract: sciatica is caused by the sciatic nerve compression in some point of its course, and its treatment consists of solving the nervous compression cause, either by surgical or conservative treatment. some physiotherapeutic resources act basically in the reduction of the symptoms caused by this disturbance. the aim of this study was to verify the effectiveness of the laser 670 nm, in two different energy densities, in the pain reduction, in rats submitted to a sciatica experimental model. eighteen rats, divided in 3 groups were used: g1 (n=6) submitted to sciatica and simulated treatment (placebo group), g2 (n=6) submitted to sciatica and treated with laser 2 j/cm2, g3 (n=6) submitted to sciatica and irradiated with laser 4 j/cm2. the hamstring nerve of the animals' right hind limb was exposed and compression with catgut thread in 4 points of the nerve was performed. on the 3rd post-operation day, the treatment was begun with laser in the surgical procedure area of the right hind limb for 10 days. the time during which the limb remained on the air was verified through gait in the following periods: previous to the sciatica, before and after treatment. the results have demonstrated that the laser was not effective in the pain reduction; however, with 4 j/cm2 there was positive effect, without complete functionality reestablishment.

Abstract: therapeutic ultrasound is a physical therapy resource for relieving sciatic pain. the aim of this study was to assess the effectiveness of continuous therapeutic ultrasound in two different power densities (0,5 w/cm2 and 1 w/cm2), on reducing pain in rats submitted to a sciatica experimental model. twenty rats were used, divided into 3 groups: g1 (n=6) submitted to sciatica and placebo treatment; g2 (n=7) submitted to sciatica and treated with 0.5 w/cm2 ultrasound; and g3 (n=7), submitted to sciatica and treated with 1 w/cm2 ultrasound. sciatica was provoked by surgical nerve compression on the right posterior limb of all animals. treatment on the surgical procedure region consisted in ten daily 5-minute sessions, starting on the 3rd postoperative day. pain was inferred by the time of paw elevation (tpe) during gait, measured before the surgery and on five further moments. results showed tpe increase in all groups after surgery; but in both groups actually treated with ultrasound a significant tep decrease was noticed, practically reaching initial values, the decrease being more precocious and intense in g2. continuous ultrasound such as was delivered was hence effective in reducing sciatic pain.

Abstract: during the inflammatory process some kinds of cells are predominant and are involved with pain production. low power laser seems to be useful in the control of inflammatory mediators, but wide divergence in the dosemetric parameters leads to variations in its positive results. the aim of this study was to assess the use of the 808nm laser in the chronic joint pain and edema of wistar rats submitted to synovitis. sample was composed of 10 wistar rats divided in two groups: cg - synovitis induction on right knee and placebo treatment; tg - synovitis induction and irradiated with 10j/cm2 laser. 100μl of 5% phormaline were injected in the right tibiofemoral joint space. pain assessment occurred by the time of paw elevation (tpe). on the 10th day after synovitis induction, laser treatment began on the knee medial joint surface and this procedure was kept for 10 days. the outcomes showed that laser presented analgesic effects, since significant reduction of the tpe values was observed for the treated group, hence indicating pain reduction when compared with the pre-treatment values; the same situation did not occur to the group which received the placebo treatment. concerning edema, laser has also shown significant reduction. it can be concluded that laser 808nm with 10j/cm2 is efficient in reduction of chronic joint pain and edema in animals submitted to experimental synovitis.

Abstract: this article proposes a discussion of the factors that contributed to the settling within the portuguese possessions along the shores of the indian ocean, namely the construction of fortresses along this coastline. these settlements represented an official strategy of establishment within the territory and of control of the commercial routes. simultaneously, however, private individuals sought other forms of becoming wealthy which were very often contrary to the portuguese crown's interests. the analysis of these two lines of action is based on the definition of strategies and tactics proposed by michel de certeau.

Abstract: this work evaluated the weed control in glyphosate tolerant soybean crop without additional management practices. two experiments were carried out under field conditions in the agricultural years 2006/2007 and 2007/2008 in jaboticabal, s?o paulo state, brazil. it was tested two glyphosate-tolerant varieties (cd 214 rr and m-soy 8008 rr), eight herbicide treatments (roundup ready, single spraying at rates of 0.48; 0.72; 0.96 and 1.20 kg ha-1 of glyphosate acid equivalent, associates or not to sequential spraying at 0.48 kg ha-1), and two controls (one under mechanical control and one untreated control). soybean varieties influenced the infestation of weed species. xanthium strumarium was predominant in control treatments, reducing the occurrence of other weeds species. independently of the dose, glyphosate sprayings resulted in low infestations 35 and 40 days after the first spraying, in the first and second year, respectively. the weed control in transgenic soybean is directly influenced for the glyphosate rate, having satisfactory control with the single application at 0.96 kg ha-1 or sequential at 0.48 plus 0.48 kg ha-1 of glyphosate. under lesser infestation conditions (2006/2007), the single application at 0.48 kg ha-1 of glyphosate is enough for weed control. the varieties of transgenic soybean cd 214 rr and m-soy 8008 rr distinguishing influence the dynamics of the weed species. the chemical control is more effective in the m-soy 8008 rr, where it had minor diversity and development of the weed.
