In vitro and in vivo activities of Chios mastic gum extracts and constituents against Helicobacter pylori.
The extracts and pure major constituents of Chios mastic gum (resin of Pistacia lentiscus var. chia) were tested for their activities against Helicobacter pylori. A total mastic extract without polymer (TMEWP) was prepared after removal of the contained insoluble polymer in order to ameliorate solubility and enhance in vivo activity. Administration of TMEWP to H. pylori SS1-infected mice over t...

It has been used for more than 2500 years in traditional Greek medicine for treating several diseases such as gastralgia and peptic ulcers, while the actions of the gum are mentioned in the works of Herodotus, Dioscorides...
متن کاملAntibacterial activities of Galla rhois extracts against Helicobacter pylori infection
In this study, a medicinal plant, Galla rhois (GR), was examined and screened for its anti-Helicobacter pylori activity. Galla rhois was extracted with 70% ethanol. Inhibitory zone tests, as in vitro assays, and an in vivo study using a Mongolian gerbil (Meriones unguiculatus) model were performed. The safety of the GR extract was then evaluated in an animal study. The Galla rhois extract demon...
متن کاملMastic gum has no effect on Helicobacter pylori load in vivo.
OBJECTIVE To determine whether mastic gum suppresses or eradicates Helicobacter pylori infection in humans. PATIENTS AND METHODS Nine patients with H. pylori infection, and without gastroduodenal ulceration, were recruited from day-case endoscopy lists and treated with mastic 1 g four times daily for 14 days. [13C]Urea breath tests (UBTs) were carried out immediately before, on day 15 and 5 w...
متن کاملIn vitro and in vivo activities of HPi1, a selective antimicrobial against Helicobacter pylori.
A high-throughput screen (HTS) was performed to identify molecules specifically active against Helicobacter pylori, the causative agent of peptic ulcer and gastric carcinoma. Currently, treatment of H. pylori infection is suboptimal, with failure rates approaching 25%, despite triple therapy with two broad-spectrum antibiotics and a proton pump inhibitor or quadruple therapy with added bismuth....
