13. NERVE ENDINGS AND VASCULAR SUPPLY IN SEMITENDINOSUS TENDON OF CEREBRAL PALSY CHILDREN
Objective:To evaluate the distribution of SP (substance P) and S-100 peptide immunoreactivity, as well as the vascular supply of tissues commonly used as grafts for anterior cruciate ligament (ACL) reconstruction. A second aim was to compare the above mentioned distribution in the semitendinosus muscle tendons of cerebral palsy (CP) patients with the semiten

14. Effects of estrogen on functional and neurological recovery after spinal cord injury: An experimental study with rats
OBJECTIVES:To evaluate the functional and histological effects of estrogen as a neuroprotective agent after a standard experimentally induced spinal cord lesion.METHODS:In this experimental study, 20 male Wistar rats were divided into two groups: one group with rats undergoing spinal cord injury (SCI) at T10 and receiving estrogen therapy with 17-beta estrad

15. Can transcutaneous electrical nerve stimulation improve achilles tendon healing in rats?
BACKGROUND: Tendon injury is one of the most frequent injuries in sports activities. TENS is a physical agent used in the treatment of pain but its influence on the tendon's healing process is unclear. OBJECTIVE: To evaluate the influence of TENS on the healing of partial rupture of the Achilles tendon in rats. METHOD: Sixty Wistar rats were submitted

16. Understanding the ligamentum teres of the hip: a histological study
Objective: To perform a histological study describing the microstructure of the ligamentum teres of the hip, with special emphasis on the presence of nerve bundles. Our study aims to correlate the microstructure of the ligamentum teres with its postulated functions, allowing greater understanding of its role within the hip joint.Methods: Fresh specimens exci

17. Stretch-induced nerve injury: a proposed technique for the study of nerve regeneration and evaluation of the influence of gabapentin on this model
The rat models currently employed for studies of nerve regeneration present distinct disadvantages. We propose a new technique of stretch-induced nerve injury, used here to evaluate the influence of gabapentin (GBP) on nerve regeneration. Male Wistar rats (300 g; n=36) underwent surgery and exposure of the median nerve in the right forelimbs, either with or

18. Current perception threshold and reaction time in the assessment of sensory peripheral nerve fibers through sinusoidal electrical stimulation at different frequencies
INTRODUCTION: The Perception Sensory Threshold (ST) for sinusoidal current stimuli at 5, 250, and 2,000 Hz is commonly used in the assessment of peripheral nerve fibers (C, Aδ, and Aβ, respectively). However, the neuroselectivity of these frequencies is far from consensus. In addition, Reaction Time (RT) measurements suggest that 2,000 Hz stimuli excite A�

19. Mapeamento anatômico e funcional das aferências nociceptivas ao núcleo paratrigeminal dos nervos facial, mediano e ciático. / Sciatic, Median and Orofacial Nociceptives Inputs to the Paratrigeminal Nucleus: a funcional and anatomical investigations.
Investigations show the paratrigeminal nucleus (Pa5) as an input site for sensory information from the facial, median and sciatic nerves fields. This study aimed at determining the facial, median and sciatic nerve projections to the dorsal lateral medulla and compared the topographical distribution of the input sites of these nerves to that of nuclear c-Fos

20. Comparative studies on the histology and ultrastructure of the siphons of two species of Tellinidae (Mollusca: Bivalvia) from Brazil
Despite the great importance of the siphons for infaunal bivalves, only a few studies have examined their tissues using histology techniques or scanning electron microscopy. In the present study, the siphons of Tellina lineata Turton, 1819 and Macoma biota Arruda & Domaneschi, 2005 were investigated. The siphon walls are composed by a series of muscle sheets

21. Alterações hemodinâmicas do tratamento da intoxicação da bupivacaína com lipídeo : estudo experimental em suínos / Hemodynamic changes in lipid emulsion therapy for bupivacaine toxicity : experimental study in swines
Introduction: local anesthetics are drugs that reversibly block the conduction of impulses along the nerve fibers. They are widely used in loco-regional anesthesia and in pain treatment, however its uses is not without risks. Cardiotoxicity is the most worrisome complication in cases of inadvertent intravascular injection of large doses and until recently wi

22. Valor preditivo da topografia de disco óptico para o desenvolvimento de glaucoma / Predictive value of optic disc topography for the development of glaucoma
Purpose: To evaluate the ability of baseline confocal scanning laser ophthalmoscopy, using the Heidelberg Retina Tomograph (HRT), in predicting the development of progression in patients suspected of having glaucoma. In addition, the study also aimed to compare the predictive abilities of the glaucoma probability score (GPS) with those of the Moorfields regr

23. Enxerto sintético e biológico, com e sem preenchimento de veia jugular externa, no reparo de nervo periférico em ratos / Syntetic and biological graft, filled with the external jugular vein in the repair of peripheral nerve in rats
Despite the development of technology involved in peripheral nerve regeneration, there is no technique that presents a recovery of the nervous tissue with completely satisfactory results. This fact arouses interest of several researchers around the word. Although the autologous nerve grafting is the current gold standard for the repair of large nerve gaps, o

24. MORFOLOGIA DO NERVO ISQUIÁTICO DE RATOS SUBMETIDOS À IMOBILIZAÇÃO DE PATA / Morphology of the sciatic nerve of rats submitted to Detention of Pata
The human body tissues change constantly, so the majority of them adapt to the new demand. The study objective is the morphological analysis of immobilized rats sciatic nerve. This is an experimental and longitudinal research which took 6 animals dividing them in GI and GC groups. Each group containing 3 animals. The immobilization kept the animals paw in ex
