Bone marrow natural killer (NK) cell activity was studied in patients with multiple myeloma. Bone marrow mononuclear cells from myeloma patients expressed considerable levels of cytotoxicity against K562 in a 4 h 51Cr-release assay, which was comparable to that of blood lymphocytes. In contrast, NK-cell activity was markedly low or absent in bone marrow of(More)
Clinical outcomes and complications of a technique used for atlantoaxial stabilization were evaluated in a group of 12 dogs. At surgery, the atlantoaxial joint was realigned and rigidly fixated using cortical bone screws, K-wire, and polymethyl methacrylate. Results in nine dogs were graded as excellent. Results in two dogs were judged as good. One dog was(More)
Patients with myelodysplastic syndrome (MDS) receiving hypomethylating agents commonly develop thrombocytopenia. This double-blind study evaluated the efficacy and safety of romiplostim, a peptibody protein that increases platelets, in patients with MDS receiving decitabine. Patients received romiplostim 750 μg (n = 15) or placebo (n = 14) and decitabine.(More)
Na-hylan, a chemically modified sodium hyaluronate jelly, was studied mechanically and histologically as a surgical device to diminish tendon adhesions in rabbit extensor hallucis longus tendons after severe surgical trauma. Na-hylan jelly of high viscoelastic properties was found to be highly effective in decreasing tendon adhesions. Na-hylan jelly of low(More)
Disruption of the actin cytoskeleton elicits profound changes in cell survival and function. The actin cytoskeleton is regulated in a hierarchical manner by Rho GTPases. Rho kinase, a downstream effector of RhoA, regulates the formation of stress fibers and focal adhesions. Disruption of the actin cytoskeleton causes apoptosis in airway epithelial cells. To(More)
Tumor-associated macrophages (TAM) isolated from pleural effusions and ascites fluids of cancer patients were tested for cytotoxicity against freshly isolated autologous tumor cells and K562 in a 4-h 51Cr-release assay, and in vitro effects of OK432 (a streptococcal preparation) and partially purified human leukocyte interferon (IFN) on their cytotoxicities(More)
PURPOSE We compared the efficacy of an SR (70 to 80 shocks per minute) and an FR (120 shocks per minute) for ESWL for solitary stones less than 2 cm located in the kidney or proximal ureter. MATERIALS AND METHODS A total of 349 patients with a solitary, radiopaque kidney or ureteral stone underwent ESWL on a DoLi(R) 50 lithotriptor. Patients were grouped(More)
BACKGROUND Palpation has been shown to be inaccurate at identifying lumbar interspinous spaces. Our goal in this study was to compare ultrasound imaging of the region to palpation. METHODS Using ultrasound in the postpartum period, we estimated the interspinous level used for obstetric neuraxial anesthesia in 121 women and compared this estimation with(More)
