PURPOSE Postoperative adhesions frequently compromise the success of flexor tendon repair. Manipulation of growth factors responsible for scar formation may be a method of decreasing adhesion formation. Transforming growth factor beta (TGF-beta) is a key cytokine in the pathogenesis of tissue fibrosis. The purpose of this study was to examine the(More)
Klinefelter's syndrome is known to be associated with various malignancies including male breast cancer and germ cell tumour. We report a patient with Klinefelter's syndrome who developed a primary B-cell lymphoma of the central nervous system (CNS). To the best of our knowledge, this is the first case of primary CNS lymphoma in Klinefelter's syndrome.
A lower incidence of Hodgkin's disease in Orientals has been recognized. Although most Hong Kong Chinese came from the Guandong province of China, the incidence of Hodgkin's disease in Hong Kong Chinese is 9.2 per cent which is more comparable to the low figure of 6 per cent in Japan than the 32 per cent incidence in Guangdong. If this discrepancy in the(More)
The theory of 'homing' mechanism has been proposed to explain the association of malignant lymphoma involving multiple sites of mucosa-associated lymphoid tissue (MALT). DNA rearrangement in the peripheral blood and bone marrow specimens of 20 patients with MALT lymphoma were studied utilizing JH and C beta gene probes, aiming to detect circulating lymphoma(More)
We describe a radioimmunoassay of serum cortisol in which 125I-tracer and preconjugated double antibody are used. This simpler method involves direct serum assay, and the majority of reagents are prepared in-house. Within-assay precision (coefficient of variation) of assay of Ortho Diognostic RIA Cortisol I and II was 3.2% (mean = 131 microgram/L, n = 10)(More)
We evaluated four immunoassay methods for determination of alpha-fetoprotein in serum. All are commercially available in kit form in North American and we find them acceptable with respect to sensitivity, stability, precision, linearity, and analytical recovery. For the Dainabott method, the median values from 16 through 20 weeks of gestation are 34.4,(More)
This is an analysis of the long-term follow-up data of 99 patients receiving HOAP-Bleo, IMVP-16 and PAC as salvage chemotherapy for refractory or relapsed intermediate or high grade non-Hodgkin's lymphomas. Most of the patients received HOAP-Bleo or PAC following failure of initial chemotherapy and IMVP-16 was used mainly for HOAP-Bleo failures. The longest(More)
One hundred and forty-one consecutive patients above and 231 below the age of 60 years with previously untreated intermediate or high grade non-Hodgkin's lymphoma were included in this study. Patients above the age of 60 years were treated with the COPP chemotherapy regimen. The younger patients, at or below the age of 60, received a doxorubicin-containing(More)
We compared two immunoassay methods for determination of alpha-fetoprotein in amniotic fluid. The two methods showed a very good correlation and this is further confirmed by the clinical study. The electroimmunoassay (rocket immunoelectrophoresis) seems suitable for a small laboratory, whereas radioimmunoassay may be a better choice for a large laboratory.
Seventeen nodal lymphomas (originally diagnosed as T-cell lymphomas based on histological features and immunohistochemical staining results) were studied for the presence of Epstein-Barr virus (EBV) genome, and the results correlated with immunoglobulin and T-cell receptor gene rearrangement analyses performed on the same tissue samples. All four EBV(More)
