The purpose of the research was to see how a nano-extract (zinc oxide) of oleander leaves affected the histological structure of the liver in male laboratory mice aged (7-8) weeks and weighing (28-35 g). They were split up into three groups, with ten mice in each. The control group made the first group. The second group was treated with an oleander leaf nano-extract at a concentration of (20 mg/kg). The group that was administered a 30 mg/kg dosage of oleander leaf nano-extract is the third group. For 30 to 45 days on a daily basis, a (30 mg/kg) concentration of the oleander leaf nano-extract was used. Half of the rodents were sacrificed at the end of the initial thirty days, and histological sections of the liver were obtained. Histological sections of the liver were obtained from the residual half, which was sacrificed after 45 days when the experiment ended. Animals injected with a Nano-extract of oleander leaves at a dose of (20 mg/kg) for 40 days had aberrant liver structure, cells, and histological abnormalities. Animals that received a 45-day injection of a (30 mg/kg) dosage of oleander leaf nano-extract also had pathological alterations and aberrant liver and central vein cell morphology.

The current study was conducted in the animal house of the Faculty of Education for Girls / University of Kufa, and the study aimed to know the effect of the nano-extract (zinc oxide) of the seeds of the Annona squamosa plant on the histological structure of the liver in male white rats with ages ranging (8-9) weeks and weights (230-244mg). Which were divided into three groups, each group included 10 rats. The first group is the control group and the second group is the group that was treated with the nano-extract of the seeds of the A.squamosa plant at a concentration (120 mg), the third group is the group that was treated with the nano-extract from the seeds of the A.squamosa plant at a concentration (200 mg/kg) per day for 30 and 45 days and after the end of the experiment The first (30) days, half of the rats were sacrificed and the tissue sections of the liver were made, and after the end of the second experiment (45) days, the other half was sacrificed and the tissue sections of the liver were made. The results of the histological study of the kidney of the white rats treated with the nano-extract of the seeds of the A.squamosa (120-200 mg/kg) for the periods 30 and 45 days showed the normal structure of Bowman’s capsule and glomerulus and the absence of histopathological changes.

Which were divided into three groups, each group included 10 rats. The first group is the control group and the second group is the group that was treated with the nano-extract of the seeds of the A.squamosa plant at a concentration (120mg/kg), the third group is the group that was treated with the nano-extract from the seeds of the A.squamosa plant at a concentration (200mg/kg) daily for 30 and 45 days and after the end of The first experiment (30) days was sacrificed half of the number of rats and tissue sections of the testes were made, and after the end of the second experiment (45) days, the other half was sacrificed and the tissue sections of the testes were made. The results of the histological study of the testes of white rats treated with the nano-extract of the seeds of the A.squamosa (120) for the periods 30 and 45 days showed the normal structure of the testes and the absence of pathological histological changes.
