Epilepsia e neuroproteção: o papel do agonista adenosinérgico A1(RPia) na modulação da crise induzida por pilocarpina
Epilepsy and neuroprotection: employment of the RPia during status epilepticus induced by pilocarpine

OBJETIVO: O objetivo desse estudo foi caracterizar a neuroproteção do RPia em ratos submetidos ao status epilepticus (SE) induzido pela pilocarpina (Pilo). MÉTODOS: Avaliou-se o balanço entre utilização local da glicose cerebral (ULGC) e fluxo sanguíneo cerebral local (FSCL) após 4 horas de SE, e...

Effects of Aspartame on Fetal Kidney: A Morphometric and Stereological Study

Int. j. morphol; 25 (4), 2007
The objective of this study was the evaluation of aspartame effects on morphometric alterations of the glomerulus, proximal and distal convoluted tubules and collecting ducts of the rat fetal kidney during organogénesis. Fifteen pregnant rats averaging 24 g body weight, were divided into 3 groups (n=5 e...

Effect of Lead Intoxication and D-Penicillamine Treatment on Hematological Indices in Rats

Int. j. morphol; 25 (4), 2007
Lead is one of the most important environmental pollution which is toxic to many organ systems. D-penicillamine (D-P) is a chelator drug which is used for treatment of lead toxicity for several years. This study was conducted in order to evaluate the efficacy of D-P in reducing the effects of lead on hem...

Histometric Study of the Epithelium of Rats Submitted to Ethanol During Lactation

Int. j. morphol; 25 (4), 2007
The present work studied the adverse effects of maternal exposure of rats to alcohol during lactation, on the development of their offspring. Histometric evaluation by karyometry and of the palatine epithelium of the sucking was performed. Two groups of animals, one coming from mothers exposed to drinkin...

Histological Evaluation of the Bone Repair Using Mineral Trioxide Aggregate Combined to a Material Carrier

Int. j. morphol; 25 (4), 2007
The aim of this study was to present a possible carrier for MTA, monoolein gel, with the objective to maintain this material in the place that was inserted and verify if this procedure is able to optimize its action. The data were evaluated by histomorphometric method and submitted to statistical analysi...

Biochemical Analysis by Calcium Determination on the Newly Formed Bone in Critical Bone Defects Submitted to Different Treatments: A Pilot Study

Int. j. morphol; 25 (3), 2007
The aim of this study was to evaluate the calcium dosage of the newly formed bone, in critical bone defects created on the calvarial tissue and filled by different substances, in male Wistar rats. A cylindrical critical bone defect (6x2mm) was created in the posterior portion, left side, on the calvarial...

Apoptosis in Denervated Skeletal Muscle

Int. j. morphol; 25 (3), 2007
The apoptosis phenomenon happens in normal tissues and in many pathological conditions as described by several researchers. Most studied in the 70s, this phenomenon remained almost forgotten in the 90s, when, with the advent of more advanced techniques, returned to laboratories. Thus, electronic microsco...

Effects of Aspartame on Maternal-Fetal and Placental Weights, Length of Umbilical Cord and Fetal Liver: A Kariometric Experimental Study

Int. j. morphol; 25 (3), 2007
Aspartame is a synthetic sweetener consumed by more than half the adult population in 75 countries. Their metabolites can be toxic, principally to the liver and retina, and there are few studies on the use of aspartame in gestation. Twenty pregnant rats were weighed and allocated randomly (n=5 per group)...

Effects of Protein and Energy Restricted Diet During Lactation Leads to Persistent Morphological Changes on Tibia Growth in the Weaned Pups

Int. j. morphol; 25 (3), 2007
The purpose of this study was to evaluate the effects of maternal protein and energy restriction during lactation on the body weight and tibiae dimensions of pups at aging. At parturition, Wistar rat dams were randomly assigned to the following groups: 1) control group (C) - free access to a standard lab...

Study of the Nuclear Volume of Testicular Cells of Rats Receiving Ofloxacin Through Lactation

Int. j. morphol; 25 (3), 2007
Ofloxacin presents an ample spectrum of antimicrobial action, including combating Mycobacterium leprae, and is currently employed as a substitute when the use of rifampicin is impossible. The objective of this work was to study alterations in testicular cell nuclei of suckling rats, whose dams were submi...
