Experimental research in rats on the reactivity of new corneal blood vessels to adrenaline.

The purpose of this experimental study was to evaluate the existence of adrenergic receptors in ketamine-induced corneal blood vessels in rat pups. The study of corneal neovascularization motricity was performed on 45-day-old Wistar rats in which, starting from the 15th day of life, corneal blood vessels were obtained by injecting intraperitoneal ketamine at a dose of 150 mg/ kg body weight, a total of 5 successive doses. The examination of the neovascularization was done with the help of a Nikon stereomicroscope connected to a video camera and a computer, the total magnification being 400X.

The effects of prostaglandins and endocannabinoids on iris arterial vascularization in Wistar rats - Experimental analysis.

The iris vascular supply originates in the anterior and long posterior ciliary arteries. The endothelium influences local blood flow by releasing endothelium relaxing and contracting substances. From a functional perspective, the ocular vascular tonus adjustment is humoral and neural dependent.

Endocannabinoid System and Ocular Vascularization.

The focus of this review is the role of endocannabinoid system in ocular and systemic circulation. By critically examining preclinical and clinical research, we explore the cannabinoid receptors localization and vascular implications as well as their interaction with other anti-inflammatory drugs. The objective is to transfer knowledge on the use of cannabinoids, specifically their effect on ocular circulation and intraocular pressure, and provide a better understanding of the endocannabinoid system complexity in modulating local and systemic circulations in order to identify potential uses and limitations of cannabinoid-based therapeutics.

The use of biologic therapies in uveitis.

Purpose: Non-infectious uveitis has been long controlled with the use of corticosteroids with many side effects and poor control in some cases. The purpose of this paper was to assess the different biologic agents (in this case infliximab and adalimumab) and to compare their efficacy in the treatment of uveitis.

Results: Adalimumab has been proven very successful in replacing or aiding corticosteroid therapy in different autoimmune mediated uveitis (Juvenile Idiopathic Arthritis, Rheumatoid arthritis, sarcoidosis) whereas infliximab has been used intravenously and recently intravitreally with very promising results in controlling Behcet's related uveitis.

Topical administration of Metamizole and its implications on vascular reactivity in Wistar rats- Experimental research.

The aim of this paper was to describe the possible implications of topical (ocular) administration of Metamizole on vascular reactivity of the iris in Wistar rats. No other study regarding its topical use was found. Male adult Wistar rats were anaesthetized with Ketamine 100 mg /kg body weight - injected intraperitoneally - while maintaining spontaneous respiration and the blink reflex.
