The present studies were undertaken to examine the expression of the high density lipoprotein (HDL) receptor, SR-B1 messenger RNA (mRNA) in ovarian cell types during folliculogenesis and luteinization using in situ hybridization histochemistry and to examine its hormonal regulation using Northern blots. For the in situ study for HDL receptor mRNA localization, 21-day-old rats were treated with ...

Normal saline or air is used to identify loss of resistance during identification of the epidural space for combined spinal-epidural analgesia. Following epidural needle placement using air for loss of resistance, up to 80% of parturients move, grimace, vocalise or experience paraesthesia or dysaesthesia during subsequent dural puncture by a spinal needle. We compared the effects of saline vers...

Through the past decades, many attempts have been made to standardize lumbar disk herniation–related terminology (1, 2). Two different, and not necessarily parallel, sets of characteristics of a herniated disk (HD) are taken into account in the reporting of cross-sectional images of the lumbar spine. First, is the absolute attributes of the HD (ie, morphology, location, volume, etc), and second...

STUDY DESIGN Multicenter, prospective, consecutive clinical series. OBJECTIVE To report on neural complications in a prospective cohort study of 1301 children undergoing spinal fusion and instrumentation for adolescent idiopathic scoliosis (AIS). SUMMARY OF BACKGROUND DATA The incidence of neural complications for spinal deformity surgery has been reported to be 0.26% to 17%. However, most ...

Vascular endothelial growth factor (VEGF) expression in granulosa cells is associated with the thecal vasculature growth during ovarian follicular development. We hypothesized that injection of VEGF gene fragments directly into the rat ovary would induce production of a large number of ovulatory follicles and that these follicles would ovulate. To test this hypothesis, we treated immature femal...

BACKGROUND AND OBJECTIVES Anesthesiologists are reluctant to consider higher levels for spinal anesthesia, largely due to direct threats to the spinal cord. The goal of this study is to investigate, with magnetic resonance imaging (MRI), the distances between the relevant structures of the spinal canal (spinal cord, thecal tissue, etc.) to determine modal anatomical positions for neuraxial anes...

To examine timed changes in the morphology of theca interna and granulosa cells of rabbit preovulatory follicles, mature female rabbits were injected with100 IU per kg of human chorionic gonadotropin (hCG) and follicles larger than1mn in diameter were excised for light and electron microscopic studies before and3, 6, 9and 12hr after hCG injection. Spindle-shaped theca interna cells had been tra...

BACKGROUND Spinal tuberculosis presents in various pathological patterns. The clinical presentation and often the management depend on exact pathological findings. Objective of study was to evaluate the Pathology of spinal tuberculosis as depicted by MRI findings in 119 consecutive cases of spinal TB. METHODOLOGY It was a cross sectional and observational study conducted at Civil Hospital, Ka...

knee surgery. the purpose of this study was to assess the analgesic effects of intra-articular injection of a dexmedetomidine following knee arthroscopy. methods:   forty six patients schadualed for arthroscopic knee surgery under general anaesthesia, were randomly devided into two groups. intervention group received 1μg/kg dexmedetomidine (d) and isotonic saline. control group received 25ml is...

conclusions although postoperative intra-articular meperidine is a better alternative for bupivacaine, their combination could improve their analgesic effects compared with each other alone. results the bupivacaine-meperidine group had better duration of postoperative analgesia (p = 0.001), latter first analgesic request (p ≤ 0.001), lower total fentanyl consumption in first 24 hours after the ...
