چکیده

Changes in the genital mucus around the oestrus are used by different diagnostic methods to determine optimal fertilisation time. In the current study, the authors evaluated the different arborisation patterns found in vestibular mucus, and also established its relationship with vestibular resistance changes during oestrus. Thirty multiparous sows were checked by transrectal ultrasonography to determine ovulation time every 12 hours. Vestibular resistance was measured with a commercial resistance probe, and vestibular mucus ferning was also evaluated every 12 hours during the oestrus. Significant changes (P < 0.05) in vestibular resistance were detected, registering high variation among individuals. Maximum resistance data was reached between 12 and 24 hours after ovulation time in 83 per cent of the sows. Crystallisation samples were classified into three different patterns according to the fern-like crystal degree. Arborisation peak occurred from 48 to 36 hours before the moment of ovulation, when vestibular resistance values increased gradually. In the optimal insemination moment, vestibular resistance increased significantly (P < 0.05) and vestibular mucus showed a low crystallisation pattern (P < 0.05). Combining several methods to measure genital mucus changes may predict the ovulation time and the best insemination moment.

    Background & Aims : Unilateral Labyrinthectomy (UL) causes a syndrome of oculomotor, postural, and autonomic system disorders which diminish over time in a process of behavioral recovery known as vestibular compensation. Many studies have been done on the vestibular compensation after unilateral labyrinthectomy (UL) and regeneration of nerve cells, but the mechanism of vestibular compensati...

Vestibular Evoked Myogenic Potential Produced by Bone-Conducted Stimuli: A Study on its Basics and Clinical Applications in Patients With Conductive and Sensorineural Hearing Loss and a Group With Vestibular Schawannoma

Introduction: Vestibular evoked myogenic potential (VEMP) has recently been broadly studied in vestibular disorders. As it is evoked by loud sound stimulation, even mild conductive hearing loss may affect VEMP results. Bone-conducted (BC) stimulus is an alternative stimulation for evoking this response. This study aims to assess the characteristics of BC-VEMP in different groups of patients.   ...

EVALUATION OF ANATOMICAL VARIATIONS OF VESTIBULAR AQUEDUCT DIMENSIONS IN TEMPOR AL BONE CT SCAN

Various dimensions of the human vestibular aqueduct were evaluated in two groups, patient and control, and these measurements were compared. Both groups were examined clinically, followed by audiometric evaluation and temporal bone high resolution CT scan. It was found that in approximately one third of the patient group (with idiopathic SNHL), the vestibular aqueduct was 1.5 mm or larger. ...
