NAPVSIPQ (NAP), an active fragment of the glial-derived activity-dependent neuroprotective protein, is protective at femtomolar concentrations against a wide array of neural insults and prevents ethanol-induced fetal wastage and growth retardation in mice. NAP also antagonizes ethanol inhibition of L1-mediated cell adhesion (ethanol antagonism). We performed an Ala scanning substitution of NAP ...

Our phytochemical study focused on the leaves of Citrus deliciosa Algerian origin, in order to evaluate its antioxidant activity and acute toxicity, using scavenger DPPH radicals, ABTS toxicity. The ethanol extract contains 85.62 ± 2.24 μg /mg dried matter 3.02 0.17 μg/mg matter. was confirmed against radical (IC50 = 252.07 0.02 /mL) 398.26 0.01 /mL). No mortality or abnormal behavior observed ...

Cytochrome P450 2E1 metabolizes ethanol and also bioactivates many toxins and procarcinogens. Elevated levels of hepatic CYP2E1 are associated with an increased susceptibility to chemical toxicity and carcinogenesis. This study investigated the induction of hepatic CYP2E1 by ethanol and nicotine, alone and in combination, in a nonhuman primate model. Monkeys that self-administered ethanol and t...

Graptophyllum pictum is a medicinal plant that helps to cure different forms of disease due the availability beneficial phytochemicals such as flavonoids, steroids, alkaloids, saponins and glycosides. The purpose this research was evaluate toxicity effect G. extract on zebrafish embryos (Danio rerio) at concentrations. extracted using ethanol method.

The mechanisms by which chronic ethanol intake induces bone loss remain unclear. In females, the skeletal response to ethanol varies depending on physiologic status (e.g., cycling, pregnancy, or lactation). Ethanol-induced oxidative stress appears to be a key event leading to skeletal toxicity. In this study, ethanol-containing liquid diets were fed to postlactational female Sprague-Dawley rats...

The goal of this study was twofold: (a) to search for possible interactive effects between two common drugs of abuse, ethanol and methamphetamine. b) To inquire whether any effects of ethanol could be replicated using an equivalent amount of ethanol in the form of red wine. Adult male C57/6N mice received 2% ethanol for 8 weeks in drinking water or red wine diluted to yield the same ethanol con...

The use of ethanol and nicotine is strongly linked; 80 to 95% of heavy alcohol users are also smokers. In humans, cigarette smoking significantly enhances CYP2E1 activity, as measured by increased metabolism of chlorzoxazone in vivo. CYP2E1 metabolizes ethanol and can generate toxic intermediates. CYP2E1 also bioactivates tobacco smoke and other procarcinogens and several hepatotoxins. We hypot...

Melastoma malabathricum (MM) is a well-known plant in Malaysian traditional medicine, locally known as senduduk. Its ethanol and aqueous extracts have been used in the present investigation to study the immunomodulatory role on human peripheral blood mononuclear cell (PBMC), and the DPPH, ABTS and FRAP free radical scavenging activities were also measured. Total flavonoids and total phenolic co...

In previous studies, we established that kolaviron (KV) (a biflavonoid from Garcinia kola seeds) elicited anti-oxidative and hepatoprotective effects in Wistar rats chronically treated with ethanol. The present study investigates the possible ameliorative effect of KV against ethanol-induced reproductive toxicity in male Wistar rats. Twenty-eight rats were randomly divided into four groups of s...
