Morphologic changes in the urethral epithelium in an ethanol-drinking rat strain (UChA and UChB)

The extreme use of ethanol causes metabolic and pathologic changes in testes and urogenital system in different animal species. The enzyme alcohol dehydrogenase (ADH) catalyses the conversion of ethanol into carcinogenic metabolite acetaldehyde which is partly excreted into the urine. However, papers relating the chronic ethanol consumption to the urethral morphology are unknown. This work evaluates the toxic effect of the chronic ethanol ingestion on the urethral epithelium of UChA and UChB rats. Conventional techniques of histology, histochemistry, immunohistochemistry and ultrastructural analysis were used. The analysis showed the presence of lipid drops and intercellular spaces in the epithelial cells in the urethra of UChA and UChB rats compared to control rats. Urethral neuroendocrine cell were observed and characterized for presenting vesicles containing electron-dense granules associated with nervous fibers. We conclude that the chronic consumption of ethanol induces the presence lipid drops in the epithelial cells of the urethra of UChA and UChB rats. The NE cells of the urethra of UChA and UChB rats did not show alterations under chronic effect of the ethanol. (C) 2007 Elsevier Ltd. All rights reserved.

THE EFFECT OF ANALOGS OF ANGIOTENSIN-II ON DRINKING AND CARDIOVASCULAR-RESPONSES TO CENTRAL ANGIOTENSIN-II IN THE RAT

1. Intracerebroventricular (I.C.V.) infusion (60 ng h-1) of Isoleu5-angiotensin II (Isoleu5-AngII) and des-amine-angiotensin II (des-amine-AngII) in rats caused increased drinking behaviour and an increase in arterial blood pressure.2. Des-amine-AngII caused similar increases in heart rate and arterial blood pressure as AngII.3. Previous I.C.V. injection of the antagonists [Leu8]-AngII, des-amine-[Leu8]-AngII and octanoyl-[Leu8]-AngII prevented the increases in heart rate and blood pressure produced by I.C.V. infusion of AngII and caused partial reduction of the dipsogenic response.4. The three antagonists had no effect on the increase in arterial blood pressure and heart rate caused by des-amine-AngII. The drinking response was reduced by previous injection of [Leu8]-AngII and des-amine-[Leu8]-AngII but not by octanoyl-[Leu8]-AngII.5. In conclusion, Isoleu5-AngII and des-amine-AngII increase drinking behaviour, arterial blood pressure and heart rate when infused into the cerebral ventricle of rats. The study with the antagonists showed that des-amine-AngII probably binds more strongly to AngII-receptors.

Effectiveness of different methods for the detection of binge drinking in dentistry students

The purpose of this study was to estimate the alcoholic beverage consumption among undergraduate students of a Dentistry Course and compare the effectiveness of screening methods for the detection of binge drinking. A total of 284 undergraduate students participated in the research. We used the full AUDIT and their reduced forms (AUDIT-3 and AUDIT-C). In addition, a ROC curve was created and its area was calculated. Of the students, 91.0% and 90.6% of the male and female genders, respectively, reported alcohol beverage consumption. Bing-drinking behavior occurred in 69.2% of the men and in 52.4% of the women. The 3 methods showed good discriminatory ability. For the women, there was a significant difference between the AUDIT-3 and AUDIT-C. Both the complete version of AUDIT and its reduced forms presented good discriminatory ability

The Bible in Medieval Love Lyrics: A Fundamental Element of European Poetry Books

The focus of this study is the relationship among three different manuscripts (Modena, Bibl. Estense, MS α.R.4.4; Firenze, Bibl. Laurenziana MS Rediano 9; and London, BL, MS Harley, 2253) and the poetry they transmit. The aim of this research is to show the ways that the Bible was used in the transmission of the lyric poetry in the three literatures that they represent: Occitan (primarily through Marcabru’s songs), Italian (through the love poetry of Guittone d’Arezzo), and Middle English (through the Harley love lyrics and the MS.’s primary scribe), in a medieval European context.

Bodily and Embodied: Being Human in the Tradition of the Hebrew Bible

A depiction of the ancient Hebrew understanding of the human being must take into account the fact that the Bible does not contain a systematic anthropology, but unfolds the multiplicity of human existence inductively, aspectively, and in narrative fashion. In comparison to Greek body/soul dualism, but also in the context of body-(de-)construction and gender debates, this circumstance makes it a treasure trove of interesting, often contrasting recollections and insights with liberating potential. This assertion will be illustrated concretely in terms of the nexus points of the human body (throat, heart, and womb), the relationship of humans to animals and angels, and the questions of the power and value of a human being.
