Figure 8. Photomicrograph of a section of the longitudinal section of the testes of Adult Sprague-Dawley rats treated for 28 days. H&E stain captured at 10x (Figure 8A) and 40x (Figure 8B) magnification. Legend: A=Control, B=Yaji, C=Red pepper, D=Black pepper, E=Cloves, F=Ginger, and G=Garlic. Yellow arrows=Tunica vaculosa, Blue arrows=Leydig cells (Interstitial cells); black asterisk=seminiferous tubule lumen, Black arrows=spermatogenic cells, and Black bracket: basal and adluminal membrane of the seminiferous tubule made up of the spermatogenic cell lineage. Controls had all spermatogenic cell series, spermatids in the adluminal compartment, proliferative interstitial cells of Leydig, and waves of spermatids in the seminiferous lumen. Similar histological features were observed in rats given Yaji, red pepper, black pepper, and ginger. The group given cloves had disruptions of spermatogenic cells series in the adluminal compartment as compared to the basal compartment of the seminiferous tubule. However, the interstitial cells were undisrupted in all study groups treated for 56 days.
