Remedial Potential of Olea europea and Punica granatum Fruit Extracts on Testicular Histopathology in Fluoride Exposed Mice.

Purpose: This study was designed to study testicular-histopathology and lipid profile against 50ppm of fluoride (ad labitum) exposure in mice. Moreover, the curative potentials of vitamin E, Punica granatum and Olea europea fruit extracts were also studied. Methods: Five groups (10 animals/group) were treated as follow (a) Control (C) (F free water-15 days); (b) NaF {50ppm F-ions in drinking water (10days) and F free water (5days)}; (c) NaF + vitamin E (NaFE) {50ppm F-ions (10days) and F free water+60µg vitamin E in corn oil (5days)}; (d) NaF+ Punica granatum fruit extract (NaFP) {50ppm F ions (10days) and F free water+0.2mL P. granatum fruit extract (5days)}; (v) NaF+ Olea europea fruit extract (NaFO) {50ppm F-ions (10days) and F free water +0.2mL O. europea extract (5days)}; All animals were sacrificed on day 16 to obtain blood for lipid profile and testes for histopathological studies. Results: Results shows peculiar histopathological changes in the testis, including the loss of interstitial tissues, spermatogonia, spermatocytes, spermatids and maturing sperms. These signs were convincingly recovered in NaFO, followed by other two post treatment groups NaFP and NaFE. Similarly the micrometric data shows significant increase in the number of spermatogonia, spermatocytes and developing spermatozoa, in NaFO (CSA of seminiferous tubules, number of spermatogonia, spermatocytes:, sperms embedded in sertoli cells & number of dislodged sperms). The rise of High Density Lipoproteins (HDL) with a simultaneous decline in plasma cholesterol, Low Density Lipoprotein (LDL) and Very Low Density Lipoprotein (VLDL) in NaFO indicate the importance of these post treatments, against altered lipid profile of the F toxicology. Excellent testicular rehabilitation found in NaFO group that indicate the curative potential of O.europea against altered histopatology against F exposure in testes. Conclusions: The severity of the mentioned pathology of NaF group indicates that Olea europea and Punica granatum post treatment can effectively eradicate the toxic changes of F exposure in lipid profile, while Olea europea fruit extract showed more ameliorationative capability against F-exposure in testes.
