Wpływ melatoniny, N-acetyloserotoniny i 6-hydroksymelatoniny na ultrastrukturę pinealocytów chomika syryjskiego (Mesocricetus auratus)

Objectives: The aim of this study was to examine the effects of melatonin as well as of its precursor (N-acetylserotonin) and metabolite (6-hydroxymelatonin) on the ultrastructure of the pinealocytes of the Syrian hamster. Material and methods: The pineal glands of 2-month-old male Syrian hamsters were examined. The animals were divided into the following groups of four animals each: group 1 — ...

Effects of nitric oxide synthase inhibition on diethylstilbestrol-induced hyperprolactinaemia and pituitary tumourigenesis in rats Wpływ zahamowania syntazy tlenku azotu na wywołane dietylstilbestrolem hiperprolaktynemię i rozwój guza przysadki

Introduction: The overexpression of nitric oxide synthase (NOS) has been found in tumours, including pituitary adenomas. It has also been found that NOS is overexpressed in human spontaneous pituitary adenomas. The question arises whether NOS and its product, nitric oxide (NO), are involved in pituitary tumourigenesis. To investigate this question, in the present paper we examine the effects of...

Effects of Aluminum Sputtering on the Corrosion Resistance of Az91 Alloy Wpływ Glinu Nanoszonego Metodą Rozpylania Jonowego Na Odporność Stopu Az91 Na Korozję

The corrosion resistance of a Magnesium alloy is low and needs to be improved. This research aimed at corrosion-resistance improvement by supatterd deposition aluminium film, which is formed on the surface of AZ91 Magnesium-alloy. Corrosion resistance performed polarization curve measurement, was evaluated in quest of the corrosion rate using the Tafel extrapolation method, and conducted surfac...
