Abstract：
:After 5 or 20 mg cyclophosphamide per kg body weight, given once i.v., the output in thoracic duct lymph of small and large lymphoid cells, cells incorporating [3H]lymidine in vitro, mitotic cells, pyknotic cells, and/or the number of lymphocytes and neutrophils in peripheral blood were measured in six calves. The median grain count of labeled cells and the DNA content of pyknotic nucleic were determined. After both doses there was an exponential decrease and subsequent recovery of the median grain count. The larger dose caused a temporary cessation of lymphoid cell division, reduced the output of nondividing small lymphoid cells, and probably imparied proliferation of neutrophil precursors. The results suggest that increased cell production during recovery was due to changes in the growth fraction and that feedback mechanisms acting on G0-G1 cells controled the proliferation of lymphoid cells.

CANCER RESEARCH文献大全abstract：:Isothiocyanates exert strong anticarcinogenic effects in a number of animal models of cancer, presumably by modulation of xenobiotic-metabolizing enzymes, such as by inhibition of cytochrome P-450 and/or by induction of phase II detoxifying enzymes. Here, we report that phenethyl isothiocyanate and other structurally ...
