The effect of a single dose of Mk-801 use on adult brain tissue after an experimental head trauma model applied in immature rats.

Objective: Within the scope of this research, the long-term effects of experimental blunt head trauma on immature rats and MK-801 administered acutely after trauma on the brain tissue will be examined. In addition, the impact of trauma and MK-801 on Nestin and CD133, which are essential stem cells, will be evaluated by immunohistochemical and ELISA methods.

Methods: In this study, the contusion trauma model was used.

Does dexamethasone therapy affect intimal hyperplasia after injury in rat abdominal aorta models?

Background: Intimal hyperplasia is a normal adaptive feature of arteries in response to injuries, which include invasive vascular interventions. Its development limits the long-term success of bypass grafts. Various pharmacological agents have been successfully employed in experimental models to reduce the degree of intimal hyperplasia.

The effect of three different mydriatic eye drops on retinal vessel diameters.

Purpose: To investigate the effects of topically applied 1% tropicamide, 2.5% phenylephrine and 1% cyclopentolate on retinal vessel calliper (VC) using optical coherence tomography (OCT).

Methods: Patients who came to the ophthalmology clinic for routine examination and whose OCT films were taken before dilatation and after 30 min of last dilatation drop were included in the study.

Macular Pigment Optical Density in First Degree Relatives of Age-Related Macular Degeneration Patients.

Purpose: To measure the macular pigment optical density in first-degree relatives of patients with age-related macular degeneration and compare it with a healthy control group.

Methods: One hundred and twenty-eight healthy subjects who were first-degree relatives of age-related macular degeneration patients were included in the study (Group 1). As the control group, 74 healthy subjects were included in the study (Group 2).

The effects of hyperbaric oxygen therapy on retinal layers in healthy eyes.

Purpose: The aim of our study is to investigate the effects of hyperbaric oxygen (HBO2) therapy on retinal layers in healthy eyes.

Method: Thirty patients who were taken to outpatient HBO2 for any indication were included in the study. All patients underwent 10 sessions of HBO2; 20 healthy patients were taken as the control group.
