No tapetal cells were formed or tapetam collapsed at very early stage in some anther chamber during the microsporogenesis; Pollen mother cells in another chamber were not developed and microspore vacuolized; Tapetum cells developed abnormally, giantized and crammed the anther chamber; Some tapetum cells developed normally, but PMCs developed abnomally, which deformed at sporogeneous stage, and then were abhensive each other and finally degenerated. Nearly no PMCs could complete the process of meiosis, and form the tetrad, leading to the failure of normal microspore development.

These results indiacated that tranferring macrophages combinedwith cytokines could be a new adoptive immunotherapy protocol foradvanced cancer,and rTNF used in vivo locally could induce andactivate macrophages to kill tumor cells.Monocytes when activatedunderwent a series of phenotypic and functional changes includingthe expression of IL-2R which may provide an important immunoregu-latory pathway.The presence of lectin-like molecules on thesurface of monocytes and tumor cells may bring theeffector/target cells together,thus facilitating the inductionof apoptosis in target cells by triggering the production ofcytolytic factors and the modification of target of targer cell surface anti-gens.(such as HLA-DR).
