Bunium persicum (Boiss.) is an economically important medicinal plant growing wildly in arid regions in Iran. The fruit of B. persicum is widely used in traditional Iranian medicine to control colic pain and dysmenorrhoea. The aim of the current study was to determine antinociceptive mechanisms of B. persicum essential oil using an acetic acid-induced writhing test as a model of visceral pain and to determine the possible involvement of opioidergic, serotoninergic and histaminergic systems on antinociceptive mechanisms of B. persicum in male mice. In experiment 1, B. persicum was intraperitoneally (i.p.) injected (0.001, 0.01, 0.05, 0.1, 0.5 and 1%; 10 ml/kg) in Tween-80 (0.5%) and a writhing test served as a model of visceral pain. In experiments 2-5, opioidergic receptor antagonist (naloxone, 2 mg/kg), serotonergic receptor antagonist (cyproheptadine, 4 mg/kg), histamine H 1 -receptor antagonist (chlorpheniramine, 20 mg/kg) and histamine H 2 -receptor antagonist (cimetidine, 12.5mg/kg) injection was followed by B. persicum (0.01%; 10 ml/kg) and the writhing test response was measured for 30 min. According to the results, essential oil of B. persicum, administered i.p. (0.001, 0.01, 0.05, 0.1, 0.5, and 1%; 10 ml/kg) in Tween-80 (0.5%), elicited antinociceptive effects in a dose-dependent manner. Moreover, the antinociceptive effect of B. persicum was significantly attenuated by pre-treatment with naloxone, chlorpheniramine and cimetidine (P < 0.001). These results suggest that B. persicum-induced analgesia may be mediated via opioidergic and histamine H 1 and H 2 receptors.
Purpose Hypothyroidism is a clinical syndrome that can lead to elevated levels of serum creatinine and uric acid by causing impaired renal function. Although many studies have been carried out on the relationship between overt hypothyroidism and renal function, few studies have been conducted on subclinical hypothyroidism and renal function, especially in pediatric patients. For this reason, we studied this issue in children, so as to provide a background for more useful research and future education.Methods This case-control study was performed on 107 children aged 2–14 years, 56 children with subclinical hypothyroidism in the case group, and 51 healthy children in the control group presenting to Ayatollah Mousavi Hospital in Zanjan and private clinics of Zanjan city. Thyroid stimulating hormone, triiodothyronine, thyroxine, creatinine, and uric acid were measured in both groups of children after obtaining the necessary criteria for entering the study.Results Compared to the control group, subjects with subclinical hypothyroidism had higher levels of creatinine (P=0.003), while serum uric acid levels in subclinical hypothyroid children was not significantly different from those in the control group (P=0.200).Conclusions In subclinical hypothyroidism in children, creatinine was higher than in euthyroid patients, but uric acid was not different.
Background:The aim of this study was to compare the response of doxycycline and bleomycin in pleurodesis of malignant pleural effusions.Materials and Methods:The radiologic and clinical responses of doxycycline and bleomycin in pleurodesis of malignant pleural effusions were compared in this randomized clinical trial. Forty-two patients were randomized to receive either bleomycin 45 mg or doxycycline 600 mg as the sclerotherapy agent. Chest X-rays were taken before and after intervention, 10 days and 2 months later to compare the radiologic response. Dyspnea and other side effects, before and after intervention, 10 days and 2 months later were recorded and compared. Chi-square test was applied to analyze the data.Results:The prevalence of dyspnea and its different severities, 10 days and 2 months after intervention were significantly different (P < 0.05) between the two groups. Analysis of pleural effusions revealed a significant difference (P < 0.05) between Doxycycline vs. Bleomycin 2 months after the intervention. Three months after pleurodesis, only one patient in bleomycin group needed pleural fluid drainage.Conclusion:Pleural effusions did not change with use of doxycycline and bleomycin in short time but long-term results of doxycycline sclerotherapy was better than bleomycin sclerotherapy in malignant pleural effusions that was supported by this study. However, additional studies with larger sample size are necessary to confirm the results.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
