Impact of passive smoking on renal vascular morphology.

Objective: To determine whether passive smoking causes morphological and structural changes in the arcuate arteries of rats exposed for 7 to 28 days.

Methods: Wistar rats aged eight weeks and weighing 260g on average were allocated to a Control or a Smoker Group. Groups were further divided into 4 groups containing 5 animals each.

Morphofunctional study on the effects of passive smoking in kidneys of rats.

Objective: To analyze whether passive inhalation of cigarette smoke causes morphological, structural, and functional changes in kidneys of rats.

Methods: Wistar rats, aged eight weeks, weighing on average 260g, were divided into Control Group and Smoking Group. Each group was subdivided into four groups of ten animals for morphofunctional analysis, in a period of seven and 28 days.

A review on alcohol: from the central action mechanism to chemical dependency.

Introduction: alcohol is a psychotropic depressant of the central nervous system (CNS) that promotes simultaneous changes in several neuronal pathways, exerting a profound neurological impact that leads to various behavioral and biological alterations.

Objectives: to describe the effects of alcohol on the CNS, identifying the signaling pathways that are modified and the biological effects resulting from its consumption.

Methods: a literature review was conducted and articles published in different languages over the last 15 years were retrieved.
