Diagrammatic scheme showing the procedural steps for preparing the Hen’s egg test-chorioallantoic membrane (HET-CAM) test (a-d); where the egg was candled to check the embryos-viability and to mark the air space (a), the external shell was removed (b), the inner membrane was removed (c) and the normal vascularization of the chorioallantoic membrane was shown (d) as well as the observed responses to different systems application (e-h); the positive control (10% NaOH; e), the negative control (0.9% NaCl; f), Terconazole-loaded SNES L7 (g) and Terconazole-suspension (h).
