The effect of absorption rate on the pharmacokinetics of ibuprofen enantiomers was investigated in 12 healthy Han Chinese male volunteers following oral administration of immediate-release (IR) and sustained-release (SR) preparations containing racemic ibuprofen (rac-ibuprofen). The area under the curve of the plasma concentration-time curve (AUC;(More)
Advanced age affects various tissue-specific stem cells and decreases their regenerative ability. We therefore examined whether aging affected the quantity and quality of cardiac stem cells using cells obtained from 26 patients of various ages (from 2 to 83 years old). We collected fresh right atria and cultured cardiosphere-derived cells (CDCs), which are(More)
OBJECTIVES To study the immediate impact of manual lymph drainage (MLD) on skin and subcutaneous tissue strains in legs with lymphedema using free-hand real-time tissue elastography (RTE). METHODS Skin and subcutaneous tissue strain measurements were taken at the middle of the inner thigh and calf by RTE in 20 legs with lymphedema of 18 patients (stage(More)
The purpose of this study was to confirm the therapeutic effects of mixed sheets consisting of peripheral blood mononuclear cells (PBMNCs) and fibroblasts on cutaneous skin ulcers. Vascular endothelial growth factor (VEGF) secretion in mixed cell sheets was much higher than in PBMNCs and fibroblasts. Concerning the mechanism, transforming growth factor beta(More)
Critical limb ischemia (CLI) causes severe ischemic rest pain, ulcer, and gangrene in the lower limbs. In spite of angioplasty and surgery, CLI patients without suitable artery inflow or enough vascular bed in the lesions are often forced to undergo amputation of a major limb. Cell-based therapeutic angiogenesis has the potential to treat ischemic lesions(More)
Objectives To investigate the adherence to and efficacy of different compression methods in elderly patients. Methods A retrospective review of compression therapy in 120 elderly patients (≥65 years) with chronic venous insufficiency was performed to study the initially preferred compression method, adherence to each method, and its efficacy. Results(More)
Purpose: To clarify the risk factors for venous stasis-related skin lesions in the legs in patients without major abnormalities on duplex ultrasonography (DUS). Methods: Fifty patients (nine males and 41 females, age 27-93 years) with symptoms of C4 or greater according to the Clinical, Etiological, Anatomical, Pathological (CEAP) classification, but having(More)
We developed mixed cell sheets consisting of fibroblasts and peripheral blood mononuclear cells that had high potency for secreting vascular endothelial growth factor. The purpose of this study was to confirm the therapeutic effects of mixed sheets in rabbits suffering from ulcers at the ischemic hind limbs. We used the ulcer model, which was constructed by(More)
Celiac stenosis may result in a pancreaticoduodenal artery aneurysm (PDAA). Celiac stenosis with a PDAA is rare and treatment guidelines are absent. Here, we report 4 cases of celiac stenosis treated using different methods. Of these, 3 involved PDAAs. The PDAAs were successfully treated with coil embolization. For celiac stenosis, we performed open surgery(More)
We developed a novel mouse model of human refractory cutaneous ulcers that more faithfully reflects pathology and evaluated the effects of mixed cell sheets comprising peripheral blood mononuclear cells and fibroblasts, which we previously developed for treating refractory cutaneous ulcers. Model development involved sandwiching the skin between two(More)
