Introduction: Myxopapillary ependymoma (MPE) is a benign and slow growing tumor that originates exclusively from the conus medullaris and cauda equina nervous tissue. It occurs more commonly in young patients. In addition, clinical presentations are non-specific and may mimic benign conditions. Magnetic resonance imaging (MRI) is the imaging modality of choice for evaluating this tumor. We here...

Ram spermatozoa from the distal caput, corpus, and cauda epididymis and ejaculated spermatozoa were artificially inseminated in 170 ewes which had been treated with an ovulatory dose of PMSG 61 ! 4 hrs previously. Results were expressed as the percent of ewes pregnant 18 days after insemination (F = with positive progesterone assay/ Q inseminated) and embryonic survival (ES = ewes lambing/ preg...

In the present work, histochemical and biochemical studies were conducted to analyze changes in the pattern of autonomic innervation during sexual maturation, using the rat epididymis as a model. Glyoxylic acid histochemistry and immunohistochemical studies against dopamine beta-hydroxylase (DbetaH) and acetylcholinesterase (AChE) indicated a reduction in the amount of catecholaminergic and ACh...

BACKGROUND Afferents from the urinary tract transmit bladder sensations to the central nervous system. Spinal cord injury (SCI) may affect both efferent motor and afferent sensory pathways. Presence/absence of bladder sensations in patients with complete spinal cord, conus or cauda equina lesions was compared with neurologically unimpaired patients. METHODS During urodynamics, bladder sensati...

Intradural lumbar disc herniation (ILDH) is uncommon pathology. In present report, authors present a case of ILDH associated with dorsal herniation of the cauda equina rootlets in a 30-year-old male laborer who had chronic backache since last two years. To the best of our knowledge we are reporting this for first time. Report demonstrates the natural course of ILDH.

OBJECTIVE Cauda equina syndrome is a relatively rare condition with a disproportionately high medico legal profile. Definitive management involves prompt surgical decompression with outcome dependent on timing of surgery. Documentation of a comprehensive clinical and neurological assessment including examination of anal tone and perianal sensation is essential in reducing litigation and identif...

A variety of mammalian species have been used in studies of epididymal function. The knowledge gained from these laboratory and domestic species has been applied to the human as well, but the anatomy and biology of the human epididymis is not commonly investigated directly. Nonpathological specimens from men within their reproductive years are understandably difficult to obtain, and even when s...

BACKGROUND Acute cauda equina syndrome is an uncommon but significant neurologic presentation due to a variety of underlying diseases. Anatomical compression of nerve roots, usually by a lumbar disk hernia is a common cause in the general population, while inflammatory, neoplastic, and ischemic causes have also been recognized. Among human immunodeficiency virus (HIV) infected patients with acq...

Caput epididymal wild-type spermatozoa and cauda epididymal spermatozoa from mice null for the adenylyl cyclase Adcy10 gene are immotile unless stimulated by a membrane-permeant cyclic AMP analogue. Both types of spermatozoa exhibit flagellar angulation where the head folds back under these conditions. As sperm proteins undergo oxidation of sulfhydryl groups and the flagellum becomes more stabl...
