The leukocyte CD44 and CD45 cell surface receptors are associated via the linker proteins ankyrin and fodrin with the cytoskeleton, which itself is important in immune cell functions such as adherence, chemotaxis, and phagocytosis. The effects of rat antihuman CD44 and CD45 monoclonal antibodies on phagocytosis of fluoresceinated heat-killed Staphylococcus(More)
The 'Tanaka-Kaiyong Line' (TKL) is a major phytogeographic boundary in Southwest China, separating East Asia's Sino-Himalayan and Sino-Japanese Floras. However, little is known about the importance of this boundary in promoting intraspecific phylogeographic subdivision and divergence. Using chloroplast (cpDNA) and nuclear-intron (nDNA) sequence data, we(More)
That L-arginine (L-Arg) augments the host response to acute bacterial sepsis suggests that this amino acid intervenes early in the immune response, perhaps via the nitric oxide synthetase (NOS) pathway. The effect of L-Arg supplementation on in vitro phagocytosis of fluorescein-labeled, heat-killed Staphylococcus aureus by peripheral blood neutrophils(More)
BACKGROUND Accelerated silicosis has become uncommon in developed countries, whereas serious health threat still exists in small-scale mining in developing countries. This study was to investigate the prevalence and risk factors of accelerated silicosis among Chinese gold miners. METHODS A cross-sectional medical examination was conducted among 574(More)
OBJECTIVE To evaluate the effects of low-intensity swimming on radiation-induced leg contracture. METHODS Forty mice were randomly and equally divided into four groups: 1) irradiation; 2) swimming before irradiation; 3) swimming after irradiation; 4) swimming after contracture, and their left hind legs were exposed to gamma irradiation of 60 Gy. The mice(More)
The immunogenicity of most polysaccharides (PSs) contained in the pneumococcal vaccine is low in children less than 2 years of age. Enhancement of immune response in early life can be induced by immunization of pneumococcal glycoconjugate as well as plasma DNA coding for cell-surface protein antigen. Pneumococcal type 19F PS conjugated with inactivated(More)
OBJECTIVE to investigate the correlation between the expression of nerve growth factor (NGF) and tissue injury in irradiated rat submandibular gland. METHODS the salivary gland regions of the rats were irradiated with a single dose of 15 Gy X-ray. The histopathological changes in the submandibular gland were observed, while the expression of NGF was(More)
Three populations (1, 3 and 6) of bone cells, derived from rat calvaria by sequential enzymatic digestion, were cultured with [3H]glucosamine and [35S]sulfate, in the presence or absence of transforming growth factor-beta (TGF-beta) or bone-derived matrigenin activity. Population 6 synthesized a chondroitin sulfate proteoglycan (PG) and responded to the(More)
