OBJECTIVE The aim of this work was to investigate the effects of methylprednisolone on the proliferation of endogenous neural stem cells (ENSCs) in nonhuman primates with spinal cord injury (SCI). METHODS A total of 14 healthy cynomolgus monkeys ( Macaca fascicularis) (4-5 years of age) were randomly divided into 3 groups: the control group (n = 6), SCI group (n = 6), and methylprednisolone therapy group (n = 2). Only laminectomy was performed in the control animals at T-10. SCI was induced in monkeys using Allen's weight-drop method (50 mm × 50 g) to injure the posterior portion of the spinal cord at T-10...

BACKGROUND/AIM: In clinical research setting, accurate and precise measurement of glomerular filtration rate (GFR) is essential to overcome the limitations of GFR estimation with equations, which are often unreliable. In recent decades, a method for measuring GFR by plasma clearance of iohexol, a non-ionic radiocontrast agent, was developed. To evaluate the safety of the procedure, we aimed to review all immediate adverse reactions that could be related to iohexol administration in our group's 25 years worth of experience...

BACKGROUND/AIMS: Osteonecrosis of the femoral head (ONFH) is a devastating orthopedic disease. Previous studies suggested that stromal-cell-derived factor (SDF)-1 was involved in osteogenesis and angiogenesis. However, whether SDF-1 potentiates the angiogenesis and osteogenesis of bone marrow-derived stromal stem cells (BMSCs) in ONFH is not clear. METHODS: BMSCs were transfected with green fluorescent protein (GFP) or the fusion gene encoding GFP and SDF-1α, and transgenic efficacy was monitored by immunofluorescence...

Cryptogenic multifocal ulcerous stenosing enteritis (CMUSE) is a rare chronic and recurrent disease with unknown etiology. It characterized by shallow ulcers, submucosa thickness, and no signs of systematic inflammation. Now, steroids are the principle therapy for CMSUE. However, still, there were few patients who did not response to it. Here, we present a young woman who diagnosed with CMUSE. She underwent a surgery because of capsule endoscopy retention. After relapse, she had received budesonide and methylprednisolone separately while both of them did not stop her disease...
