Objective: The aim of this study was to explore the analgesic activity of lyophilized juice of Punica granatum L., obtained from Hidalgo, Mexico, in theformalin test.Methods: We extracted the juice manually, filtered it and then dried down in a lyophilizer machine. We evaluated the antinociceptive effect oflyophilized juice from pomegranate in the formalin test (2%) in male Wistar rats (180–200 g body weight). Thirty minutes before the test, a dose of316 mg/kg (lyophilized juice) and acetylsalicylic acid as reference drug (100 mg/kg) both were administered intragastrically (i.g.).Results: The oral administration of lyophilized juice of pomegranate showed a significant decrease in the number of flinches in the temporal courseand a significant antinociceptive effect in nociceptive and inflammatory pain compared with the vehicle. In the same way, this effect appeared with thedrug of reference (acetylsalicylic acid 100 mg/kg i.g). Furthermore, it was shown that juice had a 34% of antinociception on overall effect versus vehicle.Conclusion: The results suggest that lyophilized juice of pomegranate has antinociceptive effect in nociceptive and inflammatory pain. Therefore, thisstudy supports the possible use of this lyophilized juice of pomegranate in the treatment of pain.

SummaryThe differences among human, rabbit and guinea-pig platelet adhesiveness as for inhibitions by adenosine, dipyridamole, chlorpromazine and acetylsalicylic acid are described, and the influence of measurement conditions on platelet adhesiveness is also reported. Platelet adhesiveness of human and animal species decreased with an increase of heparin concentrations and an increase of flow rate of blood passing through a glass bead column. Human and rabbit platelet adhesiveness was inhibited in vitro by adenosine, dipyridamole and chlorpromazine, but not by acetylsalicylic acid. On the other hand, guinea-pig platelet adhesiveness was inhibited by the four drugs including acetylsalicylic acid. In in vivo study, adenosine, dipyridamole and chlorpromazine inhibited platelet adhesiveness in rabbits and guinea-pigs. Acetylsalicylic acid showed the inhibitory effect in guinea-pigs, but not in rabbits.

The effect of sulfinpyrazone (200 mg three times a day) and acetylsalicylic acid (500 mg three times a day) on the incidence of thrombosis of arteriovenous shunts was investigated in a controlled clinical trial. In 36 patients with chronic renal failure scheduled to begin haemodialysis the same operating team constructed a subcutaneous fistula in the distal forearm. During the first six weeks after the operation the antithrombotic efficacy proved to be good for both substances. No differences of thrombotic events between the two treatment groups were statistically significant. But in contrast to acetylsalicylic acid sulfinpyrazone made no significant inhibition of platelet - aggregation; sulfinpyrazone probably will prevent the clot formation by prolonging the shortened platelet survival in uraemic patients. In a high rate of patients given acetylsalicylic acid (10 out of 17) there were local bleeding and gastrointestinal side effects. In consequence we should prefer sulfinpyrazone, because in the sulfinpyrazone group side effects were minimal and in none patient withdrawal from the study was necessitated.
