Does oregano protect against testicular toxicity produced by ethylene glycol in adult male albino rat? / ¿El orégano protege contra la toxicidad testicular producida por etilenglicol en ratas macho albinas adultas?

SUMMARY: Origanum vulgare Linn has traditionally been used as a diuretic and antispasmodic. Therefore, we investigated the active extract of Origanum vulgare for possible andrological effect and preventive effects against testicular damage using ethylene glycol rat model of testicular damage, to rationalize its medicinal use. Male Wistar rats received lithogenic treatment comprising of 0.75 % ethylene glycol injection twice with one day interval, then in drinking water, active extract of Origanum vulgare treatment (20 mg/kg) was given for 3 weeks to prevent toxic damage including loss of body weight gain and appetite, Following oral administration of EGME, a rapid decrease in testis weight associated with testicular cell damage was observed. Origanum vulgare treatment (20 mg/kg) prevented as well as reversed toxic changes including loss of body weight gain.

RESUMEN: Origanum vulgare Linn se ha usado tradicionalmente como diurético y antiespasmódico. Por lo tanto, investigamos el extracto activo de Origanum vulgare por su posible efecto andrológico y efectos preventivos contra el daño testicular utilizando el modelo de rata de etilenglicol de daño testicular. El objetivo del estudio fue racionalizar su uso medicinal. Su utilizaron ratas Wistar macho que recibieron un tratamiento litogénico de una inyección de etilenglicol al 0,75 %, dos veces con un intervalo de un día, y luego se administró en agua potable. Se administró el extracto activo del tratamiento con Origanum vulgare (20 mg / kg) durante 3 semanas con el objetivo de prevenir el daño tóxico, la pérdida de peso corporal y el apetito. Tras la administración oral de EGME, se observó una rápida disminución del peso de los testículos asociada al daño de las células testiculares. El tratamiento con Origanum vulgare (20 mg / kg) logró prevenir y revertir las alteraciones tóxicas, incluyendo la pérdida de peso corporal.

A Morphometric Study of the Sella Turcica: Gender Effect.

Background and objective: Precise anatomical knowledge of the sella turcica is important for neurologists and surgeons operating in the region of cavernous sinus or the surrounding structures. The current study was undertaken to record normal morphometric parameters for future reference and to determine if there is any significance difference in the sella turcica morphometry regarding the gender. Methodology: A Morphometric analysis of the Sella Turcica and structures in vicinity were done in thirty six adults’ formalin fixed cadaver’s skulls (22 male and 14 female). Results: The pituitary stalk positions weremiddle inmajority ofmale cases (72.7%), the remaining 27.3% were posterior. Among female; 57.1%weremiddle and the remaining 42.9%were posterior, no anterior position was detected among both genders with no different between male and female (p = 0.494) Normal Optic chiasma position was detected in all female cases and in 63.6% of male cases with no significant differences regarding gender (p= 0.070). No significant different in diaphragma sella shape and opening regarding gender (p.value = 0.170 and 0.914 respectively) No significant difference betweenmales and females concerning linear dimensions of sella turcica (length, depth and Anteroposterior diameters). Concerning diaphragma sella opening; no significant different regarding gender in transverse diameter (p.value= 0.316) while significant different was detected in anteroposterior diameter (p.value= 0.046) For interclinoid (anterior, posterior) diameters, which represented statistically significant different regarding gender in both right and left sides (p.value = 0.004 and 0.001 respectively). Conclusion: Present studywill providing the normalmorphometric data for future reference and further studies.
