A Master's thesis in the College of Education/Al-Qurna at the University of Basrah examined the title: "Study of the effect of active compounds of hot aqueous extract of basil leaves on some hematological, biochemical, and histological parameters of diabetic-induced male rats," presented by the student Nour Al-Huda Nazem Abdullah.

The thesis included identifying the active compounds in the hot aqueous extract of basil leaves, and studying their effect on hematological, biochemical, and histological parameters after inducing diabetes in laboratory male rats using alloxan, and treating them with the extract within specified periods.

The thesis aimed to find out the effects caused by the administration of the toxic alloxan compound on hematological, biochemical, and histological parameters, and to determine the histological changes that occur after extract administration and treatment.

The thesis concluded that there is an effect of the active compounds in the hot aqueous extract of basil leaves in improving some hematological, biochemical, and histological parameters associated with diabetes in laboratory rats.
