Effects of thymoquinone and curcumin on the regeneration of rat livers subject to 70% hepatectomy.

Purpose: To investigate thymoquinone, curcumin and a combination of these two drugs were effective or not at the growth of liver.

Methods: Forty female Wistar-Albino rats distributed into five groups of eight rats each, control, thymoquinone, curcumin, and thymoquinone/curcumin groups. Pathological specimens were studied using the Ki-67 Proliferation Index(PI); and arginase(Arg), tissue plasminogen activator(tPA), ceruloplasmin(Cer) and nitric oxide(NO) were studied in biochemical analysis.

Reduction of side effects of hyperbaric oxygen therapy with thymoquinone treatment in rats.

Introduction: Hyperbaric oxygen (HBO₂) treatment results in elevated production of reactive oxygen species (ROS) that leads to cellular damage. Thymoquinone (TQ) is reported to have anti-inflammatory and antimicrobial activity and may suppress the generation of free radicals. The goal of this study is reduction of side effects of hyperbaric oxygen therapy with thymoquinone treatment.

Evaluation of ceruloplasmin levels in patients undergoing surgical interventions with nasal polyps.

Objective: Oxidative stress is believed to have a role in the development of nasal polyps (NPs). It is also known that ceruloplasmin (CP), an acute phase protein, limits oxidative stress. The purpose of this study was to evaluate the ceruloplasmin levels in patients with NPs.

An extra-large ovarian mucinous cystadenoma in a premenarchal girl and a review of the literature.

Objective: Epithelial ovarian neoplasms are extremely uncommon in children. Ovarian mucinous cystadenoma is benign and an extremely rare presentation in the premenarchal period. We present a case of giant mucinous cystadenoma of the left ovary in a 13-year-old and a review of the supporting literature.

Urinary retention as the presentation of Bartholin's duct cyst in a neonate.

Patients with a vaginal mass (large Bartholin's duct cyst) associated with a contralateral renal cyst and hydroureteronephrosis are unable to urinate. While occasionally seen in adults, Bartholin's duct cyst is rare in neonates. The origins of Bartholin's and Gartner's cysts can be traced to the mesonephric duct.

A retrospective study on the coexistence of hydatid cyst and aspergillosis.

Objectives: Hydatid cyst is a zoonotic disease with an endemic regional distribution, and Aspergillus is a saprophytic fungus that may cause allergic pulmonary aspergillosis, aspergilloma, and semi-invasive and invasive aspergillosis. The coexistence of a saprophytic fungus and hydatid cyst is extremely rare. The aim of this retrospective study was to evaluate the coexistence of aspergillosis and echinococcosis in archival materials and to discuss its probable clinical significance.

Vascular plexus is a differentation criterion for muscularis mucosa from muscularis propria in small biopsies and transurethral resection materials of urinary bladder?

Objective: Smooth muscle fibres are found within the superficial lamina propria of urinary bladder (Muscularis Mucosa). These muscle fibres of muscularis mucosa should be distinguished from the muscularis propria in cases with urothelial carcinoma, because the depth of infiltration affects prognosis and therapy modalities. The aim of the present study was to evaluate whether the presence of vascular plexus is a criterion for muscularis mucosa and to distinguish it from muscularis propria in urinary bladder biopsies and transurethral resection specimens.
