Based on these results and relevant data,immature fiber number was calculated. Results show that the carding process makes the immature fiber number increase. After carding, immature fibers are distributed mainly in card sliver,accounting for approximately 90% in their total number. All of the cylinder screen,taker-in and flat have the functions of excluding immature fibers; furthermore,IFC in cylinder screen droppings is the highest,followed successively by those in taker-in droppings,flat strips and card sliver. The IFC of card sliver is the lowest when the taker-in speeds are 1000 and 1400 r/min.展开更多

(TWH) users were investigated by electron microscopy. No macrophages were demonstrated in the 21 specimens collected prior to the administration of TWH. However, it was found in 23 out of the 48 semen specimens obtained following the TWH administration. The macrophages were functionally active as shown by the presence of a large number of cytoplasmic processes and pseudopodia on the surface, and primary and secondary lysosomes in the cytoplasm. The macrophages phagocytized sperm debris and degenerated or dead spermatids with formation of specific phagosomes. Around those macrophages, lymphocytes were commonly noted. The cytoplasmic processes of the two cell types could come into contact or even fuse with each other, leading to tight junction-like structure; in some of the contacts, the plasma membranes were found dissolved so as to form direct cytoplasmic linkage.展开更多

Methods: 116 family members of hospitalized psychiatric patients were interviewed with a self-designed inventory of health education. Results: Family members indicated poorest knowledge with respect to psychotherapeutic medication, strategies for preventing relapse, and management of family nursing. They also indicated the greatest need for knowledge in relation to effects and side-effects of psychotropic medication, monitoring of effects of psychotropic drugs, and measures to prevent relapse of mental illness. The most acceptable formats of health education were instructions by medical staff and recommendation for relevant reading materials.Conclusion: Mental health education should be based on the needs of patients’ family members and be delivered in acceptable formats.展开更多
