Acid a-naphthyl acetate esterase (ANAE), a cytoplasmic marker was used to identify the T lymphocytes and their subpopulations in peripheral blood of mice experimemally infected with T. spiralis. The results showed that the absolute number of lymphocytes and T lymphocytes increased in parallel on d, after infection, reachiug the peak on d14, and remaining above normal level on d60. The spotted granular ANAE positive cells (Helper T cells, Th) were decreasing and the scattered granular ANAE positive cells (suppressor T cells, Ts) were increasing, leading to a lowering of the Th/Ts ratio which was most marked on d14 and returned to normal on d60. The depres-sion of host immune function during T. spiralis infection might be related to the lowering of Th/Ts ratio.

Objective:To investigate the effects of genistein (Gen) on apoptosis in human osteoblast. Methods:Human periosteum was maintained in DMEM medium containing 10% newborn calf serum through four passages to isolate and proliferate osteoblast. Then, cells were maintained in phenol red-free DMEM supplemented with 5% charcoal-stripped FCS for 4 d before addition of treatments. Flow cytometer and DNA fragment were used to explore apoptosis in osteoblast, and immunohistochemistry was used to study protein expression of Bax, Bcl-2 and caspase-3. Results:Estrogen depletion could induce apoptosis in human osteoblast. With the similarity of 10-8 mol/L E2, at the conentrations of 10-6 mol/L and 10-5 mol/L, Gen could inhibit apoptosis induced by estrogen depletion. Compared with vehicle control, Gen significantly decreased protein expression of Bax and caspase-3 and increased protein expression of Bcl-2. Conclusion:Genistein could inhibit apoptosis induced by estrogen depletion in human osteoblast.
