Condition of embryos (1.5 hpf) and media immediately after exposure about (a) Control, (b) N-Ag-PVP, (c) HP, (d) N-Ag-PVP+HP, (e) Hym176 and (f) N-Ag-PVP+Hym176 (c, chorion).

The effects of the N-Ag-PVP with Hydra materials (HP, Hym 176) and pure N-Ag-PVP on the development of zebrafish. Embryos were exposed to (a) Control, (b) N-Ag-PVP(1 mg/L), (c) HP(4 mg/L), (d) N-Ag-PVP+HP(1 or 4 mg/L), (e) Hym176(4 mg/L) and (f) N-Ag-PVP+Hym176(1 or 4 mg/L). These images show exposed zebrafish at 72 hpf. Abbreviations: i, inflammation; t, tail; n, notochord; e, edema; k, kidney; y, yolk sac
