Fig 1.
Scheme and micrograph of the hepato-nephrocitic system.
In the micrograph the arrow shows the heart valve.
Fig 2.
Scheme and micrograph of the hepato-nephrocitic system of the control group.
(A) Noticed intact trophocyte (tr) and oenocyte (oe) in close association. (B) Pericardial cells (pc) forming a layer around the dorsal vessel (dv). (C) Detail of the cordonal pericardial cell in stage I, showing intracytoplasmatic vacuoles (arrow) and some eosinophil granules (gr). n = nucleus, l = lumen.
Fig 3.
Scheme and micrograph of the hepato-nephrocitic system of the experimental group.
(A) Noticed that the trophocyte (tr) and oenocyte (oe) degenerated and present signs of cellular death (arrows). (B) The pericardial cells (pc) forming a layer around the dorsal vessel are in stage IV and the dorsal vessel (dv) present signs of degeneration (arrows). (C) Detail of the cordonal pericardial cell in stage IV (sIV), showing a large intracytoplasmatic vacuole that occupies all the cytoplasm (asterisk) and the nucleus (n) located at the cell periphery. (D) Large quantity of different types of hemocytes (he) in the dorsal vessel (dv). l = lumen.
