Background: To evaluate amniotic fluid pro- and anti-inflammatory cytokine levels in women with postterm and term pregnancies in labor and not in labor.

Methods: The study involved three groups: postterm (Group 1, n = 29), term in labor (Group 2, n = 28), and control (Group 3, n = 30). All groups were compared with respect to age, gravidity, parity, obstetric history, gestation week, cervical dilatation and effacement, maternal serum C-reactive protein and white cell count, amniotic interleukin 4, 6, and 10 levels, birthweight, and cord blood pH.

Effects of the Oral Nutritional Supplement Containing Arginine, Glutamine, and Hydroxymethylbutyrate (Abound®) on Healing of Colonic Anastomoses in Rats.

We evaluated the effects of the oral nutritional supplement containing arginine, glutamine, and hydroxymethylbutyrate (Abound®) on healing of colonic anastomoses in experimental rat model. Seventy Wistar-Albino male rats were divided into seven groups. Colon transection and anastomosis were performed in all groups except for the sham group.

The Effect of Montelukast on Liver Damage in an Experimental Obstructive Jaundice Model.

Background: Montelukast is a cysteinyl-leukotriene type 1 (CysLT1) selective receptor antagonist. In recent years, investigations have shown that montelukast possesses secondary anti-inflammatory activities and also antioxidant effects. For this reason, we aimed to determine the possible effects of montelukast on liver damage in experimental obstructive jaundice.

Impairment of thiol-disulfide homeostasis in preeclampsia.

Aim: To investigate the effects of severity of preeclampsia on thiol-disulfide homeostasis (TDH).

Material And Methods: A total of 108 participants were divided into three groups: Group 1 was composed of pregnant women with no obstetric complications, Group 2 included pregnant women with mild preeclampsia, and Group 3 consisted of pregnant women with severe preeclampsia. TDH parameters were determined, and comparisons of clinical and routine laboratory test findings were made in all groups.

The effect of sildenafil and udenafil on testicular damage following ischemia-reperfusion injury in rats.

Purpose: Ischemia-reperfusion injury can cause testicular damage and phosphodiesterase inhibitors are reported to regulate antioxidant activity. We investigated the prevention of ipsilateral and contralateral testicular damage using 2 phosphodiesterase inhibitors after testicular detorsion in rats.

Materials And Methods: A total of 28 adult male rats were randomly divided into 4 groups of 7 each, including group 1-sham operation, group 2-testicular torsion and detorsion, group 3- testicular torsion and detorsion with sildenafil administration before detorsion and group 4- testicular torsion and detorsion with udenafil administration before detorsion.

Does the method of expression of venous blood affect ischaemia/reperfusion damage in tourniquet use? An experimental study on rabbits.

The aim of this study was to compare the ischaemia and reperfusion phases of two tourniquet application models (Group 1: expressing the blood by a sterile rubber bandage and Group 2: elevation of the limb for several minutes) using an analysis of ischaemia/reperfusion parameters and blood pH. Sixteen New Zealand rabbits were used. Muscle samples were extracted from the triceps surae; at phase A (baseline: just before tourniquet application), phase B (ischaemia: 3h after tourniquet inflation) and phase C (2h after tourniquet deflation).

Nebivolol improves renal function in patients who underwent angioplasty due to renal artery stenosis: a pilot study.

Renal artery stenosis (RAS) is a progressive disease and may lead to chronic kidney disease by deterioration of renal functions. Endothelial dysfunction is an important causative factor for kidney damage after RAS revascularization. Nebivolol, a new generation beta blocker induces endothelium-related arterial relaxation by nitric oxide (NO) and may improve endothelial dysfunction.

Background And Objective: Tourniquet use is a common tool in surgical procedures of the limbs. Hydroxyethyl starch (HES) 130/0.4 not only has a role in replacement of the liquid deficits due to trauma, bleeding or shock, but it is also effective in enhancing tissue oxygen tension and regulation of microcirculation.

Ginkgo biloba (EGB 761) affects apoptosis and nitric-oxide synthases in testicular torsion: an experimental study.

Introduction: We investigated the effect of ginkgo biloba on germ cell apoptosis and also on expressions of endothelial (eNOS) and inducible (iNOS) nitric oxide synthases after testicular torsion.

The mechanisms underlying the stimulation of pain in CEH are not clearly known. In this study, we measured serum nitrate and nitrite levels as an index of nitric oxide (NO) activity in 15 patients with CEH during headache and headache-free periods and in 15 healthy controls.

Increased nitrosative and oxidative stress in platelets of migraine patients.

The molecular mechanisms of migraine have not been fully clarified yet. Increased nitrosative and oxidative stress may be associated with migraine attacks. Platelets may play an important role in migraine patients and they can reflect the lability of tissues to nitrosative/oxidative stress.
