Effect of Botulinum Toxin Type A on Mandibular Fracture Healing: An Experimental Study in Rabbits.

Purpose: The effect of botulinum toxin type A (BTX-A) on fracture healing of the long bones is controversial, and no controlled clinical or experimental study has investigated the effect of BTX-A on mandibular fractures. The purpose of this study was to investigate whether BTX-A injection into the masseter muscles affects bone healing by reducing the displacing forces in an unfavorable mandibular fracture model.

Materials And Methods: Forty-eight male New Zealand white rabbits were used.

The ultrastructural effects of surgical treatment of hydrosalpinx on the human endometrium: a light and electron microscopic study.

Hydrosalpinx is a disease commonly observed in women and characterized by the obstruction which is in the shape of a fluid-filled sac at the distal part of tuba uterina closed to the ovary. In this study, we aimed to obtain endometrial tissue samples from the hydrosalpinx patients, before and after the surgical treatment and compare these endometrial tissue samples by using light and electron microscope. Endometrial tissue samples were obtained from the 24 women with bilateral hydrosalpinx range 19-46 years before and after the surgical treatment, and normal endometrial tissues were collected from five women without hydrosalpinx and evaluated as a control group.
