The role of sensory-affective bias and of two types of experience (simple exposure to an odor and exposure to an odor in association with conspecifics) in the establishment and maintenance of preference of rat pups for odorants was investigated. (a) Simple exposure of pups to a mildly aversive odorant (peppermint extract) from birth to 21 days of age was sufficient to establish a preference for...

helicobacter pylori infection is one of the most common human infections which have been associated with many upper gasterointestinal complications. different treatment regimens for helicobacter pylori eradication have been used. one of these regimes is the quadruple therapy regimen which metronidazole is one of the medications. in recent years several reports on h. pylori resistance to this an...

INTRODUCTION Peppermint is an efficient medicinal plant for the treatment of diseases, and it also can be used to produce raw materials in the pharmaceutical industry. The purpose of the current study was to evaluate the effects of various levels of peppermint alcoholic extract on body-weight gain and blood biochemical parameters in adult male Wistar rats. METHODS This experiment was conducte...

in order to investigate the effects of peppermint (mentha piperita l.) alcoholic extract on liver injury caused by the oxidant carbon tetrachloride (ccl4), an experiment was performed as a completely randomized design in a factorial arrangement (2 × 2) with 4 replications of 10 broilers each. factors included two levels of peppermint leaf alcoholic extract (0 and 2 ml/kg body weight) and ccl4 (...

conclusions due to phenolic content, methanolic extract of m. piperita has moderate antibacterial and antifungal properties against the aforementioned gram positive and gram negative bacteria and fungi strains. materials and methods the methanolic extract was prepared by standard procedure, and total phenol, total flavonoid, and total anthocyanin content were determined using a spectrophotomete...

The methanolic extracts, infusions, decoctions and hydrosols of six plants were investigated for their total phenolic contents, antioxidant and antimicrobial activities: Mentha piperita (Peppermint), Thymus vulgaris (thyme), Melissa officinalis (lemon balm), Ocimum basilicum (basil), Rosmarinus officinalis (rosemary) and Salvia officinalis (sage) (Lamiaceae). Total phenolic contents were determ...

The aim of this study was to investigate the effects of polyacrylic acid polymers (Ultrez 10, Ultrez 20, Carbopol 980, and Carbopol 940) on the viscosity and the in vitro permeation of phenolic compounds from the gel prepared from natural horse chestnut seed extract. Experiments were performed in the presence and in the absence of peppermint oil (Mentha piperita). Our results showed that pepper...

Mentha piperita L. (peppermint) possesses antimicrobial properties, but little is known of its ability to modulate macrophages. Macrophages are essential in bacterial infection control due to their antimicrobial functions and ability to link the innate and adaptive immune responses. We evaluated the effects of the peppermint leaf hydroalcoholic extract (LHAE) on cultured murine peritoneal macro...
