photomicrograph
Figure 2: (A) A photomicrograph of an ovarian section of adult female albino rat of the control group (group I) showing cortex containing unilaminar primary follicles (UL), secondary follicles (S) at different stages of growth. Corpora lutea (CL) and atretic follicles (A) are also demonstrated. Note the presence of cortical blood vessel (V). The medulla (M) contains loose connective tissue rich in blood vessels (V) (H and E X100); (B) A photomicrograph of an ovarian section of adult female albino rat of the control group (group I) showing that the germinal epithelium appears formed of a single layer of cuboidal cells (black arrows). The cortex contains several primordial follicles (P), unilaminar primary follicles (UL), multilaminar primary follicle (ML) and a part of a corpus luteum (CL). Note the presence of cortical blood vessels (V) with simple squamous endothelial lining (green arrows) (H and E X400); (C) A photomicrograph of an ovarian section of adult female albino rat of subgroup IIa (1 week after chemotherapy administration) showing shrunken ovary with irregular outline (arrows) exhibiting massive loss of follicles and many atretic follicles (A). A degenerated corpus luteum (blue arrow) is observed (H and E X100); (D) A photomicrograph of an ovarian section of adult female albino rat of subgroup IIa (1 week after chemotherapy administration) showing massive loss of follicles with several atretic follicles (A). One atretic follicle shows shrunken oocyte and dislodgment of granulosa cells (arrowhead). A corpus albicans (CA) is evident in addition to a degenerated corpus luteum (blue arrow) (H and E X100); (E) A photomicrograph of an ovarian section of adult female albino rat of subgroup IIb (5 weeks after chemotherapy administration) showing irregular outline of the ovary with many atretic follicles (A) with the presence of unilaminar primary follicle (UL) and secondary follicles (S), some of which are degenerated (red arrows). A part of corpus luteum (CL) and a degenerated corpus luteum (blue arrow) are observed (H and E X100).
