ABSTRACT
We aimed to evaluate the effects of detorsion and Allium sativum (garlic oil) treatment on the ovarian reserve in an ovarian torsion model. Ovarian torsion may lead to loss of ovarian tissue and infertility. It is an experimental rat study that was carried out on 16 sets of ovaries each, one for treatment group and a control group. In the control group, the procedure involved only the surgically opening and closing the abdomen. Bilateral adnexal torsion/detorsion was performed after a 3-hour ischemia period for the detorsion-only group. The detorsion + Allium sativum group received a 5 ml/kg dose of Allium sativum intraperitoneally, 2 hours before surgery. After the second surgery, removed ovarian samples were evaluated for follicle counts, damage scores and other parameters. Primordial, preantral, small antral and large antral follicle counts were significantly higher in the detorsion + Allium sativum group. Degeneration, congestion, hemorrhage ,inflammation and total damage scores were significantly elevated in the detorsion only group compared to those for the detorsion + Allium sativum group. Finally, there was a significant correlation between AMH alterations and postoperative, preantral follicle count (p<0.05). As a conclusion detorsion + Allium sativum treatment may be effective in protecting the ovarian reserve after torsion.
Intentamos evaluar los efectos de la detorsión y el tratamiento con Allium sativum (aceite de ajo) en la reserva ovárica en un modelo de torsión ovárica. La torsión ovárica puede ocasionar pérdida de tejido ovárico e infertilidad. Este es un estudio experimental en ratas que se llevó a cabo en 16 sets de ovarios para cada grupo: tratamiento y control. En el grupo control, el procedimiento involucró solamente la apertura y el cierre quirúrgicos del abdomen. La torsión / detorsión anexial bilateral se realizó después de un período de isquemia de 3 horas para el grupo de solo detorsión. El grupo de detorsión + Allium sativum recibió una dosis de 5 ml / kg de Allium sativum por vía intraperitoneal, 2 horas antes de la cirugía. Después de la segunda cirugía, las muestras ováricas eliminadas se evaluaron para recuentos de folículos, puntajes de daño y otros parámetros. Los recuentos de folículos antrales primordiales, preantrales, antrales pequeños y grandes fueron significativamente mayores en el grupo con detorsión + Allium sativum. Los puntajes de degeneración, congestión, hemorragia, inflamación y daño total fueron significativamente elevados en el grupo de solo detorsión, en comparación con los del grupo de detorsión + Allium sativum. Finalmente, hubo una correlación significativa entre las alteraciones de AMH y el recuento de folículos preantrales postoperatorios (p <0,05). Como conclusión, el tratamiento con detorsión + Allium sativum puede ser eficaz para proteger la reserva ovárica después de la torsión.

Stavudine (Zerit, d4T) is widely used as an anti HIV infection drug. It prevents HIV by altering the genetic material of healthy cells but causes mutations in mitochondrial and nuclear DNA. It also produces clastogenic effects in mice. In the present investigation, comet assay test was applied to evaluate the possible genomic damage caused by stavudine and also the ameliorating effects of garlic oil and vitamin E against its genotoxicity in different organs of mice. Two different doses of garlic oil (low and high dose) and vitamin E were administered to mice separately and in combination for six consecutive days followed by a dose of stavudine. The mice were sacrificed after 24, 48 and 72 h of stavudine administration. Both the antioxidants (vitamin E and garlic oil) separately and in combination reduced the genotoxicity of stavudine. The protective effects of high doses of garlic oil were more pronounced as compared to vitamin E administered group.

Feeding a diet containing 20% of sesame oil (SO) or coconut oil (CNO) along with 2% cholesterol to rats for two months showed differences in their serum and tissue lipid profile and certain enzyme activities. Hyperlipidemia and related oxidative effects were more pronounced in coconut oil fed rats than those fed sesame oil. Feeding a combination of the oils (10% CNO +10% SO) lowered significantly the hyperlipidemia and certain other deleterious effects of CNO. Feeding a polar fraction of garlic oil (PFGO) prepared in the same way as for ajoene and administered at a dosage of 100 mg/kg along with each of the above oil containing diets counteracted significantly the hyperlipidemic, oxidant and also most of the other deleterious effects of the oils like raised lipid levels in serum and tissues, raised serum levels of AST and tissue levels of HMGCoA reductase and the lowered serum and tissue levels of glutathione reductase. The results support the claims that ajoene, the major polar compound of garlic oil, has very good biological action, which warrants further study.
