Allopurinol in refractory epilepsy: A double blind study
Togha M, Ahmadi B, Akhondzadeh Sh, Razeghi S,
Volume 65, Issue 11 (1 2008)
Abstract

 Background: Approximately 5-10% of epileptic patients do not respond to antiepileptic drugs. Adenosine has an inhibitory effect on the nervous system and its metabolism is prevented as a side effect of allopurinol, a xanthine oxidase inhibitor. The current study evaluates the efficacy of allopurinol in intractable epilepsy.

Methods: In this double-blind case-control clinical trial, of the 38 epileptics with intractable seizures, 18 received 300 mg allopurinol daily and 20 received a placebo as adjuvant treatment to their previous antiepileptic drugs. The patients were first examined two weeks after initiation of the treatment and then monthly for a total of six months, during which they were evaluated for seizure control and possible side effects.

Result: Of the 38 participants, 32 patients completed the study. There were significant differences between the two groups in terms of reduction in the total number of seizures over the entire six-month trial. A seizure reduction of 30% observed in 66% of the patients, 50% in 55%, and 60% in 44% of the cases in the allopurinol group was achieved after two months and persisted throughout the study. Furthermore, a significant difference in seizure duration was found between the two groups in month four of the trial. In the allopurinol group, two patients had transient rashes, two patients had mild nausea, and two experienced dizziness however, only one patient discontinued the drug due to dizziness. In the placebo group, one patient had rash and one had nausea. In addition, no significant hematological or hepatic changes were found during the trial in either group.

Conclusions: The results suggest that allopurinol is a safe and effective adjuvant agent in refractory epilepsy. Based on this study, we suggest that purine metabolic pathways and the specific use of allopurinol should be further investigated for the treatment of refractory epilepsy.

Volume 79, Issue 7 (October 2021)
Abstract
Background: Gender differences in scientometric indicators among medical faculty members in Iran was investigated.
Methods: The Research performance of the faculty at all universities and institutes of medical sciences in Iran was assessed using the Iranian Scientometric Information Database (ISID) on June 12, 2021. Selected variables in our study were name, gender, university, degree, academic rank, type of faculty, the total number of articles, the total number of citations, self-citation percentage, h-index, citation per article, international cooperation percentage, and the number of research collaborators. The Kruskal-Wallis test was used. The extracted data were analyzed using R v4.0.1 statistical software.
Results: A total of 21064 faculty members in 77 universities and institutes of medical sciences were registered in the ISID database, of which 12093 (57.4%) were men. Men faculty members outnumbered women in all academic ranks, except for the “instructor” rank (1134 female instructors against 835 male). In both sexes, most faculty members were assistant professors. There were more articles (346837 vs. 146024) and citations (5177060 vs. 1639246) by men than women. Among the 1789 faculty members with zero articles, 902 (50.4%) were men. One-hundred-and-fifty-four people were among ESI's top researchers' list, with a majority of men (124 people equal to 80.5%). The medians of all the scientometric indicators were higher in men than women. Men had a higher number of articles, the number of citations, h-index, citation per article, percentage of international articles, and co-authors, however, women had lower self-citations (1.56% vs. 2.51%). In all academic ranks, men had higher scientometric indicators. The only exception was the associate professors’ self-citation, in which women’s citations were higher than that of men (3.5 vs. 3.3). The highest mean h-index was in men with a Ph.D. in Pharmacy (13), men with a Ph.D. by Research (12) and women with a Ph.D. by Research (8.5), respectively.
Conclusion: Gender differences were evident in research performance in Iran. Women faculty members of medical sciences in Iran generally had lower scientometric indicators.

Evaluation of the brain tissue oxidative stress status during sepsis after mesenchymal stem cell's conditioned medium administration in male rats

Abstract
Background: In the present study, we hypothesized that conditioned medium (CM) derived from mesenchymal stem cells attenuates the brain oxidative stress in sepsis induced by the cecal ligation and puncture (CLP) model.
Methods: This study was performed in the Department of Physiology at Tehran University of Medical Sciences from August 2018 to April 2019. Conditioned medium was collected from mesenchymal stem cells isolated from rat's adipose tissues at the second culture passage. Male Wistar rats weighting (220-250 g) were randomly divided into three experimental groups (n=8 each): Sham, Sepsis and CM. Sepsis was induced by cecal ligation and puncture model in the Sepsis and CM groups. Animals in the CM group received the conditioned medium from 5×105 mesenchymal stem cells (2 h after sepsis induction, i. p., 3-5 mL). The systolic blood pressure and O2 saturation were measured 24 h after the treatment. The plasma and brain tissue samples were taken for inflammatory and oxidative stress assessment, respectively.
Results: Septic rats showed a significantly lower systolic blood pressure and O2 saturation level. They also had a significant increase in the plasma inflammatory indices (tumor necrosis factor-alpha [TNF-α], interleukin-6 [IL-6]) and brain malondialdehyde (MDA) content as well as a significant reduction in the brain superoxide dismutase (SOD) activity compared to the Sham group. The CM group had significantly higher systolic blood pressure and O2 saturation level compared to the septic rats. The animals in the CM group showed a significant attenuation in the plasma inflammatory indices (TNF-α and IL-6) and brain MDA content while having a significantly higher brain SOD activity compared to the Sepsis group.
Conclusion: Our findings showed that conditioned medium derived from mesenchymal stem cells has protective effects in preventing the inflammatory and oxidative stress status and may be suggested as a promising treatment in patients suffering from sepsis and septic shock.
