Background & Objective: Herbal medicine has an old history with a broad application all over the world. Many researches have focused on the curative as well as antinociceptive effects of herbal extracts. In the previous study the analgesic effect of Chamomile extract containing 2 mg/kg essence in Rats which revealed a significant analgesic effect were studied. In this study it is planned to compare the analgesic effect of chamomile extract and Morphine (as a standard analgesic) in mice.

  Methods: This experimental study was carried out in Shahid Sadughi Medical School on 48 Syrian mice (25-30 grams) which were randomly divided into 8 groups. In this study the analgesic effect of intraperitoneal administration of Chamomile extract containing 2 mg/kg essence and different doses of Morphine (0.5, 1.0 and 2.0 mg/kg) were assessed by using Formalin Test (for chronic pain during 1 hr. post Formalin injection) and Tail Flick Test (for acute pain during 2 hr. post drug administration in 15 min. time intervals).

  Results: The results of this study showed that 2^nd phase of Formalin Test had more analgesic effect than that of 0.5 mg/kg morphine. In the case of Tail Flick Test its analgesic effect was prominent 30-90 min. after drug administration which was identical to the analgesic effect of 1.0 and 0.5 mg/kg Morphine Sulfate (P > 0.05).

  Conclusion: Data from this study confirms the analgesic effect of chamomile essence which was indicated in our previous study and that this analgesic effect is comparable with 1 mg/kg of morphine sulfate in both the Formalin TEST & Tail Flick TEST. Chamomile as an analgesic should be studied more in different studies.

Background & objectives: Most of coronary angiography patients have not enough information about undergoing procedure . This lack of knowledge makes anxiety in patients and thereby changes their vital signs. There is no study regarding the effective education of patients based on their native language. This study was done to investigate the effect of video education in native language on vital signs caused by anxiety of patients undergoing coronary angiography.

Methods: This quasi experimental study was done in 2013 on 160 patients undergoing angiography in Imam Khomeini Hospital in Ardabil. Participants were divided into two groups randomly (80 in each group): case (native video education) and control groups. The sheets of hemodynamic variables were completed in determined time intervals for data collection. ANOVA with repeated measures and Chi square were used to analyze the data in SPSS13 software. P-value<0.05 was considered statistically significant.

Results: The results of repeated measures ANOVA showed significant improvement in vital sign variables except for temperature in both groups over the time (p<0.05). And there was significant difference in the mean vital sign variables in determined time intervals (p<0.05).

Conclusion: Video education in native language decreases the vital signs in coronary angiography patients. Therefore the video education especially in native language is recommended for improving vital signs before invasive procedures.
