Cytotoxicity and hepatoprotective attributes of methanolic extract of Rumex vesicarius L

Biol. Res; 48 (), 2015
BACKGROUND: To evaluate the hepatoprotective potential and invitro cytotoxicity studies of whole plant methanol extract of Rumex vesicarius L. Methanol extract at a dose of 100 mg/kg bw and 200 mg/kg bw were assessed for its hepatoprotective potential against CCl4-induced hepatotoxicity by monitoring act...

Hepato-protective effect of rutin via IL-6/STAT3 pathway in CCl4-induced hepatotoxicity in rats

Biol. Res; 48 (), 2015
BACKGROUND: Carbon tetrachloride (CCl4) induces hepatotoxicity in animal models, including the increased blood flow and cytokine accumulation that are characteristic of tissue inflammation. The present study investigates the hepato-protective effect of rutin on CCl4-induced hepatotoxicity in rats. RESULT...

Effect of carbamazepine and gabapentin on excitability in the trigeminal subnucleus caudalis of neonatal rats using a voltage-sensitive dye imaging technique

Biol. Res; 48 (), 2015
BACKGROUND: The antiepileptic drugs carbamazepine and gabapentin are effective in treating neuropathic pain and trigeminal neuralgia. In the present study, to analyze the effects of carbamazepine and gabapentin on neuronal excitation in the spinal trigeminal subnucleus caudalis (Sp5c) in the medulla oblo...

Mechanisms involved in reproductive damage caused by gossypol in rats and protective effects of vitamin E

Biol. Res; 48 (), 2015
BACKGROUND: Gossypol is a chemical present in the seeds of cotton plants (Gossypium sp.) that reduces fertility in farm animals. Vitamin E is an antioxidant and may help to protect cells and tissues against the deleterious effects of free radicals. The aim of this study was to evaluate the mechanisms of ...

An experimental model of disuse in the alveolar rat bone: A histomorphometrical study

Acta odontol. latinoam; 28 (2), 2015
Lack of mechanical stimulation is known to cause disuse osteopenia in bones. However, experimental models for disuse osteopenia on bones other than jawbones are not applicable to jawbones. The little available information in this field has been applied to the study of overeruption of teeth lacking antago...

Impairment of bony crypt development associated with hexavalent chromium exposure during tooth eruption

Acta odontol. latinoam; 28 (3), 2015
Improperly treated hexavalent chromium-containing industrial wastes contaminate drinking water, potentially affecting children taking breast milk or baby bottles prepared with infant formula. Thus, the aim of the present work was to determine the effect of this toxic on bone activity in the developing al...

Use of human fascia lata in rat calvarial bone defects

Acta odontol. latinoam; 28 (3), 2015
Tooth loss leads to a decrease in alveolar bone volume, and consequently to the need for guided bone regeneration (GBR) techniques to restore bone anatomy, and the adequate choice of therapy. Fascia lata membrane (FLM) has been used in surgical procedures in neurology, orthopedics, otorhinolaryngology, c...

Ensaios preliminares em ratas wistar com extrato hidroetanólico de calunga (Simaba ferruginea St. Hil. ) v. o., nas fases gestacionais de implantação, organogênese e período fetal: interferências na prole

Rev. bras. plantas med; 17 (3), 2015
RESUMO A susceptibilidade dos conceptos a agentes químicos varia muito em cada estágio do desenvolvimento. Devido a isto, a maioria dos países passou a exigir a análise do potencial para afetar todos os aspectos da reprodução (espermatogênese, acasalamento, prenhez, parto e lactação) para o dese...

Ganglionic cells apoptosis in retinal layer of rat offspring due to gestational diabetes

Int. j. morphol; 32 (4), 2014
Previous studies have shown the adverse effects of gestational diabetes on hippocampal neuronal density in animal models. This study was conducted to determine the effect of gestational diabetes on retinal ganglionic cell density, the thickness of the retinal layer and apoptotic ganglionic cell density i...

Plastination technique in laboratory rats: an alternative resource for teaching, surgical training and research development

Int. j. morphol; 32 (4), 2014
Today, alternatives methods are developed for the use of laboratory animals for teaching, research and surgical training. In our work we present a novel alternative to the use of rats, by developing a technique of plastination at room temperature. High-quality rat preparations from the anatomical dissect...
