Comparison of anti-inflammatory and analgesic effects of Ginger powder and Ibuprofen in postsurgical pain model: A randomized, double-blind, case-control clinical trial.

BACKGROUND: Ginger has been used as an herbal drug for a long time for the treatment of chronic inflammatory conditions. MATERIALS AND METHODS: This randomized, double-blind clinical trial was conducted on 67 healthy adults with at least one impacted lower third molar. Participants were randomly allocated into three groups: Ibuprofen, Ginger, and placebo. Evaluation of inflammation was done by measuring cheek swelling, mouth opening ability, serum C-reactive protein (CRP) levels, and visual analog scale (for pain scoring). The number and the time of using rescue medication were recorded too. RESULTS: Sixty patients completed the study. In all three groups, there was a significant increase in the mean cheek swelling measures, compared with the baseline, until day 5. The reduction in mouth opening ability was significant in all three groups, compared with the baseline, until day 5. There was no significant difference between ibuprofenand ginger groups in pain scores in all follow-up days. Number of required rescue medication on the day of surgery was significantly more in the placebo group. No significant or strong correlations were found between CRP levels and clinical findings. CONCLUSION: Within the limitations of this study, it can ban be concluded that gingerpowder is as effective as ibuprofenin the management of postsurgical sequelae. Furthermore, CRP levels alone are not suggested for the assessment of anti-inflammatory effects of drugs.

The relationship between gastric cancer and Helicobacter pylori in formaldehyde fixed paraffin embedded gastric tissues of gastric cancer patients-scorpion real-time PCR assay findings.

Gastric cancer is the second leading cause of cancer-related deaths worldwide and it seems that environmental and lifestyle factors and infection with Helicobacter pylori (H. pylori) have had a major role in the etiology of gastric cancer. The aim of this study was to investigate the presence of H. pylori DNA in archival gastric tissues of patients with gastric cancer disease by rapid, sensitive and specific technique of Scorpion Realtime PCR. This retrospective cross-sectional study was performed on 285 paraffin embedded gastric specimens of patients who were pathologically proved for gastric cancer admitted in Bou-Ali, Shahid Rajaie and Dehkhoda hospitals and Bahar and Farzam private laboratory in Qazvin city in Iran during 2009 and 150 paraffin embedded pathological specimens of patients with other proved diagnosis other than gastric cancer. Results of our Scorpion Realtime PCR analysis showed that DNA of H. pylori DNA was present in 78.42% of our total specimens. Modified McMullen's Staining of paraffin embedded sections was positive in 210 patients. Also we were not able to finding significant relationship between demographic characteristics of our studied patients and presence of H. pylori DNA in their formaldehyde fixed paraffin embedded gastric tissues samples. Existence of H. pylori in gastric tissue samples of patients with gastric cancer is controversial and our results indicated that in our studied specimens prevalence of H. pylori was significantly more than recent published reports.
