Effects of nigella sativa oil on allergic rhinitis: an experimental animal study.

Objectives: Nigella sativa oil is known antiallergic and immunomodulatory effects. We aimed to compare this oil with mometasone furoate, a topical steroid, on a rat model in the prevention of allergic rhinitis symptoms.

Methods: A total of 28 two-to-four-month-old Wistar Hannover rats weighing 250-350 g were randomly divided into four groups of seven, which included control, allergic rhinitis, mometasone furoate, and Nigella sativa oil groups.

Comparison of preoperative diagnostic accuracy of fine needle aspiration and core needle biopsy in parotid gland neoplasms.

Background: Fine needle aspiration (FNA) and core needle biopsy (CNB) are two commonly used approaches for the diagnosis of suspected neoplastic parotid gland lesions. We aimed to compare the diagnostic efficiency of FNA and CNB performed with ultrasound guidance preoperatively for the diagnosis of parotid neoplasms.

Methods: We retrospectively analysed the preoperative specimens of 113 patients (66 FNA, 47 CNB) who underwent surgical excision at our institute between 2014 and 2017.
