The mutagenicity of seed powder and seed oil of transgenic CryIA cotton to mammals and fish was evaluated in this study. The raw cotton seed powder or seed oil was mixed into mice and fish's diet. Cyclophosphamide and NaF were used as positive controls respectively. Regular cotton seed powder and seed oil were used as negative controls. The micronucleus frequency in mice bone marrow polychromatic erythrocytes and in eripheral erythrocytes of Zebrafish were assayed in this study. The sperm malformation rate in mice was also investigated.

Analysis of the relation between serotonin and its receptor in OFC and stress depression(n=8):(1) Microinjection of 5-HT into OFC significantly shortened immobility time, dejections have no great changes; though locomotor、 grooming activitives have little increased, they have no significant difference; rearing scores greatly reduced;(2)microinjection of pCPA into OFC significantly prolong immobility time, dejections have no great changes; locomotor、rearing activities are greatly reduced, but have no significant effect on grooming activity receding;(3)compared with the effect of 5-HT alone, microinjection of spiperone combined with 5-HT into OFC, significantly prolong immobility time and greatly reduced dejections; locomotor、 rearing、 grooming activities are all reduced, but have no significant differences.
