According to the karyokinetic phase in which the movement is caused by
repulsive force, we can distinguish two cases: a prophasic and an anaphasic. In
the prophasic movement, the chromosomes are led to the formation of the
equatorial ...

An important fact about prophasic shortening is the existence of a new prophasic
spiral of a diameter lesser tiian that shown by the old prophasic spiral (RESENDE
, 1940). If the shortening of the chromonemata were due solely to a visible ...

On the contrary, other nuclei containing more or less dispersed chromosomes
are considered as prophasic (see, e.g., experiment 2, fig. 7, 8). The nucleus of
figures 2 and 3 is a kind of centred nucleus provided of two weakened poles with
...
In these abnormal nuclei due to pederin action, the clearing of the nucleoplasm is
thus delayed, just as if they had difficulties in transforming themselves and in
taking their real prophasic structures: the stage of dense blue stained
nucleoplasm ...

From the results described above, it may be concluded that neocarzinostatin
exerts influence initially upon pre-prophasic stage of tumor cells and irregularities
of chromosomes follow after the partial reversal of neocarzinostatin action.

X 3250 Very few premeiotic cells are found showing a typical prophasic
appearance of mobilizing chromosomes, contracting and becoming more heavily
condensed. From this observation, it seems that the definitive prophase of the

A distinct pre-prophasic effect was manifest in the diploid variety after a short
treatment (25 to 48 hrs.) and also after a longer action of the fungicide. By
contrast, in the tetraploid variety the pre-prophasic effect of the fungicide "R"
could be ...
