This work is a morphometric study of several parenquimatous structures of rats' submandibular gland which were submitted to experimental cronic alcoholism and others which were recovered after detoxication during 30 days. It was used 3 groups (5 rats in each group): Control, Alcoholic and Detoxicated. The fact of alcohol acts in body tissues, take us to believe that changes in the submandibular glands morphology of rats which were submitted to cronic alcoholism can happen. In fact, after… Expand
O efeito da dieta alcoólica sobre o desenvolvimento da glândula submandibular de Rattus novergicus é definitivo? The effect of alcohol diet in the development of the submandibular gland of Rattus novergicus is definitive?
TLDR
It could be concluded that alcohol alters the development of salivary glands in rats, but this alteration is not definitive if the animal is submitted to a period of alcoholic detoxication. Expand
Histomorfometria da glândula submandibular de rato (Rattus novergicus) submetidos à dieta alcoólica - Parte II Morphometric evaluation of submandibular gland of rat (Rattus Novergicus) submited to the alcohol diet - Part II
TLDR
It can be concluded that the alcohol alters the morphology of the structures of the submandibullary glands of the rats. Expand
Effects of cachaça, a typical Brazilian alcoholic beverage, on submandibular glands of rats: a histomorphometric and biochemical study
TLDR
Chronic consumption of cachaça can cause morphological changes associated with glandular atrophy, loss of biochemical functionality of phosphatases, and the reduction of mucin synthesis. Expand
Immunohistochemical changes and atrophy after chronic ethanol intoxication in rat salivary glands.
TLDR
It is suggested that ethanol induces histological and morphometric changes in salivary glands of female rats intoxicated with ethanol during adolescence, and the mechanism underlying these alterations needs to be investigated but may be not related to the inflammatory process. Expand
Macroscopic assessment of exposure to ethanol and alcoholic detoxification on gastric lesions in rats
TLDR
Ethanol consumed chronically or after alcohol detoxification triggered gastric lesions in AC and DE, but sharply in the group submitted to detoxification, which can characterize a possible synergism between ethanol consumption and alcohol detox post-stress in the pathogenesis of gastric ulcer.

Avaliação morfométrica da glândula submandibular de Rattus Novergicus submetidos à dieta alcoólica – Parte I
A ingestao cronica de alcool pode provocar alteracoes morfologicas em diferentes tecidos. Ratos machos foram submetidos a dieta alcoolica de forma gradativa com alcool a 6%, 15% e 25%. Apos o periodoExpand
Chronic exposure to inorganic mercury induces biochemical and morphological changes in the salivary glands of rats.
TLDR
Evidence is highlighted, for the first time, that inorganic mercury is able to alter the morphology and oxidative biochemistry in salivary glands when exposed for a long time in low doses. Expand
Chronic cachaça consumption affects the structure of tibial bone by decreasing bone density and density of mature collagen fibers in middle-aged Wistar rats
TLDR
Chronic cachaça consumption affects the structure of the tibial bone of middle-aged rats by decreasing the bone density and reducing the density of mature collagen fibers. Expand
Oral lesions in elderly patients of a community in Brazilian Northeast.
TLDR
The oral health of this population is precarious, and there is a high prevalence of oral lesions, and a statistical association between injuries and using prosthesis, medicine and calculus is verified. Expand
Histometric Study of Alveolar Bone in Rats Submitted to Ethanol During Lactation
TLDR
It is posible concluir that el etanol al 20% en el agua de beber, administrado a ratas lactantes, provoca los siguientes efectos: reduccion significativa del peso corporal, alteraciones of las trabeculas del hueso alveolar, observadas estereologicamente. Expand

Lipomatöse Atrophie der Glandula parotis bei chronischem Alkoholkonsum
TLDR
Light microscopic and electron microscopic investigations of the parotid gland tissue showed a striking fat accumulation compared to control rats, reflecting an atrophy of the secretory parenchyma and appears to be responsible for the impaired saliva secretion after chronic ethanol consumption. Expand
Effects of acute ethanol administration on stimulated parotid secretion in the rat.
TLDR
When rats were previously habitually exposed to ethanol at a twice daily dose of 4 ml of 35% ethanol in water, the inhibitory action of acute ethanol administration was abolished and there was significantly depressed [Na+] in both high-flow and low-flow saliva samples, suggesting the possibility of enhanced ductal resorption developing in rats exposed to long-term ethanol feeding. Expand
Histological analysis of parotid and submandibular glands in chronic alcohol abuse: a necropsy study.
TLDR
Neither grossly detectable parotid enlargement nor acinar hypertrophy, a feature which has previously been noted as characteristic of alcoholic sialadenosis, were evident in this series, which provide little structural support for the reportedly increased secretory capacity of salivary glands in chronic alcohol abuse. Expand
Effects of chronic ethanol consumption on the rat parotid gland.
TLDR
Two-month-old Wistar rats ingested 10% ethanol for 12 months had extensive ductal and acinar oncocytic transformation; numerous atypical acinar cells showed anisocytosis, polyploidism and hyperchromatism, features that were absent in controls. Expand
[Alcohol and fertility: sex hormones].
TLDR
Increased oestrogenial effects are found in connection with changes regarding synthesis, metabolism, conversion, as well as intravascular and intracellular (receptors) binding proteins in patients with chronic alcoholism. Expand
Effects of ethanol during the onset of female puberty.
TLDR
Results indicate that ETOH-treated animals showed significantly lower body weights and a significantly longer mean VO-D1 interval than the control animals; however, serum GH and LH levels were significantly lower in the ETOh- treated animals; but, FSH levels were not affected. Expand

Until two decades ago, dietary deficiencies were considered to be the only reason for alcoholics to develop liver disease. As the overall nutrition of the population improved, more emphasis wasExpand
Ultrastructural study of the ventral lobe of the prostate of rats submitted to experimental chronic alcoholism
TLDR
The effects of chronic alcohol ingestion on the ventral lobe of the prostate were studied in rats (Rattus norvegicus) and epithelial cells showed signs of degeneration. Expand
The nominal section thickness--importance of their correction for morphometry.
TLDR
The real finite section thickness of histologic slices is measured with a nominalsection thickness of 2, 4 and 6 microns with a microinterferometrical method and analogue differences in the estimation of the fictive volume densities and in the Sholpo-corrections are found. Expand
