Background: Various studies have tested quality of life (QOL) among drug addicts, however very few have reported any association between oral health-related quality of life (OHRQOL) and mode of drug administration among drug addicts. Hence, the present study was conducted aiming to evaluate the impact of mode of administration of drugs on OHRQOL among drug addicts. Methods: Data was collected u...

Background: The adverse effects and increased resistance of drugs necessities the discovery novel combination therapy. Objectives: This study aimed to examine Artemisinin plus glucantime or shark cartilage extract on Iranian strain Leishmania major (MRHO/IR/75/ER) in vitro vivo. Methods: In experiments, their different concentrations (3.12 - 400 µg/mL) promastigotes, amastigotes, un-infected ma...

Methylphenidate (MP) (ritalin) is widely used in the treatment of children and adolescents with attention deficit hyperactivity disorder, but little is known about therapeutic mechanisms or about possible consequences of long-term exposure. To more closely simulate the clinical use of the drug, we orally administered MP to adolescent rats during the dark-active phase of the circadian cycle at d...

BACKGROUND Dicloxacillin, a semisynthetic isoxazolyl penicillin antibiotic, has antimicrobial activity against a wide variety of gram-positive bacteria including Staphylococcus aureus, Streptococcus pyogenes, Streptococcus pneumonia, Streptococcus epidermidis, Streptococcus viridans, Streptococcus agalactiae, and Neisseria meningitidis. The objective of this study was to evaluate the safety and...

Marmoset cytochrome P450 2C19, highly homologous to human P450 2C9 and 2C19, has been identified in common marmosets (Callithrix jacchus), a nonhuman primate species used in drug metabolism studies. Although genetic variants in human and macaque P450 2C genes account for the interindividual variability in drug metabolism, genetic variants have not been investigated in the marmoset P450 2C19 In ...

Initial administration of 60% nitrous oxide (N2O) to rats at an ambient temperature of 21°C decreases core temperature (Tc), primarily via increased heat loss (HL). Over repeated N2O administrations, rats first develop tolerance to this hypothermia and subsequently exhibit hyperthermia (a sign-reversal) due primarily to progressive increases in heat production (HP). When rats initially receive ...
