From: Prenatal and maternal study of halloysite toxicity in pregnant rats
Representative photomicrographs of rat fetal pancreas sections stained with Hematoxylin–Eosin stain (magnifications 100x and 50X): (A) normal control fetal pancreas (group A) revealed normal islets of Langerhans(I)with normal acinar arrangements (AC). The fetal pancreas of both groups of rats treated with halloysite intranasally (B), and those rats treated with halloysite orally (C and D) showed destroyed islets of Langerhans (I), congestion of the blood vessels(C), and atrophied blood vessels (A). The acini were destroyed (Head of arrow) and surrounded by oedema (thin arrow). Also, there was peri-vascular oedema (Thick arrow).
