Background: This article reviews experimental and clinical studies in which neural injuries repaired with bone marrow stromal cells. History: Bone marrow contains two kinds of stem cells: hematopoietic and nonhematopoietic (stromal) stem cell. In vitro studies indicate that bone marrow stromal cells have the capacity of differentiation into other cells (such as neural cell) under treatment wit...

nerve entrapment at the wrist or hand that can cause motor, sensory or combined motor and sensory loss depending on the localization of entrapment along the canal. The most common etiological factor is the compression of the ulnar nerve at the wrist by a ganglion. However, other conditions such as anomalous musculotendinous arches, lipomas, diseases of the ulnar artery, fractures of the hamate,...

OBJECTIVE To determine if primary hand osteoarthritis (OA) is associated with abnormal bone and anthropometric traits. METHODS We used DXA to measure total body bone mineral density (BMD), femoral neck width (bone size) and total body lean and fat mass in 39 subjects with hand OA (primary DIP and/or CMC I) and 164 controls. Data are presented as mean Z-scores or Odds Ratios (OR) with 95% conf...

The incidence and clinical features of temporal bone fractures have been well documented in the medical literature. Characteristically, longitudinal fractures account for 80% of the total [1, 2] and result from trauma to the parietal and temporal regions of the skull [3]. The fracture line starts at the tympanic annulus and runs parallel to the petrous pyramid, traversing the external auditory ...

Bone cancer pain has been reported to have unique mechanisms and is resistant to morphine treatment. Recent studies have indicated that neuron-restrictive silencer factor (NRSF) plays a crucial role in modulating the expression of the μ-opioid receptor (MOR) gene. The present study elucidates the regulatory mechanisms of MOR and its ability to affect bone cancer pain. Using a sarcoma-inoculated...

Histochemical study revealed that transcutaneous injection of ethanol into the vicinity of the pterygopalatine ganglion greatly decreased the positive staining for NADPH diaphorase activity after 1 week in the ipsilateral ganglion of a dog and abolished the staining of perivascular nerves in the middle and posterior cerebral arteries. Transmural electrical stimulation or nicotine produced a rel...

We report two rare cases of adult-onset phalangeal microgeodic syndrome (PMS), which commonly develops in children. Both cases were Japanese women, with case 1: 60 years old and case 2: 58 years old. They developed swelling and stiffness in their fingers in winter, and their symptoms disappeared without any treatment in summer. Magnetic resonance imaging (MRI) of bilateral hands showed diffuse ...

Tuberculous dactylitis is an unusual form of osteoarticular tuberculosis involving the short tubular bones of hands and feet, which is uncommon beyond six years of age. We report the case of a fifteen-year-old adolescent boy who was diagnosed with tuberculous dactylitis, involving contralateral hand and foot. His diagnosis was delayed due to lack of suspicion of this rare entity. The report als...

Effects of adrenaline on K+ -activated hyperpolarization of bullfrog sympathetic ganglion cells, preganglionic nerve axons and splanchnic nerve axons were studied. The K+ -activated hyperpolarization recorded from ganglion-postgangaline (0.3 mM). On the other hand, the K+ -activated hyperpolarization of postganglionic, preganglionic nerve axons and splanchnic nerve axons was not affected under ...
