Abstract
Background: Antibiotics are commonly prescribed drugs by dentists. Irrational use of these drugs can lead to unwanted drug side effects, such as drug resistance in addition to unnecessary costs. This research was conducted to determine the antibiotic prescription pattern by dentists of Ardabil City based on the international ATC/DDD system.
Methods: In this cross-sectional descriptive study, 250 prescriptions of patients referred to dentists in Ardabil during the second quarter of 2021 were examined. The information related to prescribed drugs includes: drug dose, frequency of drug use, number of drugs that were collected and completed in the dental offices and clinics of Ardabil city, and finally after converting the data into a certain daily dose based on the ATC-DDD system, acquired data was analyzed using One-way analysis of variance and Tukey's post hoc tests and SPSS version 21 software, the significance level was considered less than 0.05.
Results: Out of the total 250 reviewed prescriptions, 207 prescriptions (82.8%) contained antibiotics. Metronidazole (73.4%) and amoxicillin (70.5%), were the most antibiotic drugs prescribed by Ardabil dentists respectively. In all prescribed drugs, the DDD value was higher than the standard DDD value. There was no significant difference between men and women in terms of the number of copies (p<0.05). The highest frequency was related to the prescription of three drugs and the lowest frequency was related to the prescription of six drugs. In terms of pharmaceutical forms, 201 prescriptions (97.1%) were only oral drugs and 6 (2.9%) were both oral and injectable
Conclusion: The results showed that the amount of antibiotics prescribed in prescriptions was higher than the standard DDD and the number of drugs prescribed in prescriptions was also higher than the figure recommended by the World Health Organization.

Abstract
Background: A zoonotic obligate intracellular protozoan parasite, Toxoplasma gondii, infects all warm-blooded animals as well as humans worldwide. Identification of the level of infection in intermediate hosts gives us an important data about understanding the role of this parasite in human health as well as estimating the economic loss in livestock. Therefore, the main aim of this study was the isolation and identification of T. gondii from aborted goat fetuses by PCR in Lorestan province.
Methods: From autumn 2023 to summer 2024, the brain and liver of 100 goat fetuses were examined for T. gondii by PCR based on the amplification of 529 base pair fragments from repetitive regions of the parasite genome. The study was performed in three aborted fetus groups, less than 2 months, 2 to 4 months and more than 4 months.
Results: From a total of 100 examined samples, conventional PCR detected the T. gondii infection in 6 (6%) and 2 of the brain and liver fetuses respectively.
Conclusion: This study shows a notable level of infection in goat fetuses, and as a result, T. gondii should be considered an important agent involved in the abortion of goats in the Lorestan province of Iran. On the other side, it is necessary to pay more attention to the risk of transmission of this parasite from farmed animals to humans, especially pregnant women and people with suppressed immune system.

Abstract
Background: Poisoning is one of the common causes of hospital emergency department referrals, especially in adolescents and young people; therefore, knowing the pattern of poisoning will be helpful in identifying risk factors and early detection of poisoning. The aim of this study was to investigate the epidemiology of acute poisoning in adults referred to Imam Khomeini Hospital in Ardabil from 2017 to 2020.
Methods: In this descriptive-analytical and retrospective study, 755 cases related to poisoned patients referred to Imam Khomeini Hospital in Ardabil from 2017 to 2020 were reviewed. The extracted data include ward, gender, age, marital status, place of residence, general status, cause of poisoning, and time of referral, were recorded on the checklist. Obtained Data were analyzed by Chi-square test and SPSS25 software.
Results: The results showed that drug poisoning, opium (opium and its derivatives) and pesticides were the first to third ranks of the most poisoning agents. Most of the poisoned patients were men, married, in the age group of 21 to 30 and living in urban areas. Most of the poisonings were intentional and 33 deaths (4.4%) happened due to poisonings. The cause of poisoning had a significant relationship with age, sex, marital status, place of poisoning (p<0.05) but had no significant relationship with the general condition and time of patients' referral.
Conclusion: Acute poisoning is a major health problem in Ardabil province. The results show that the three agents of drug poisoning, opium and pesticides are the main means of poisoning in adults. Most cases of poisoning occurred in young and adult groups and were in the age range of 21 to 30 years. Poisonings occurred in people aged 31 to 40 were more due to amphetamine. Poisoning with aluminum phosphide tablets had increased compared to before. Consumption of aluminum phosphide is one of the problems of today's societies and it was one of the main causes of death in this research, so it is better to provide necessary measures for management and training for its correct use. Also, by limiting the use of these agents and replacing other methods and techniques, poisoning with these agents can be reduced.

Abstract
Background: Premature ovarian insufficiency (POI) is the cessation of ovarian function in women under 40. One of the mechanisms involved in the induction of POI is oxidative stress. This study aims to investigate the effect of caffeic acid on the morphometrical changes of ovarian follicles of POI model mice.
Methods: Thirty-two female mice were randomly divided into 4 groups (n=8): 1) Control group (cont), 2) Caffeic acid group (CAF), 3) Premature ovarian insufficiency group (POI), and 4) Premature ovarian insufficiency + Caffeic acid group (POI+CAF). POI was induced through daily subcutaneous injections of D-galactose (200 mg/kg) for 6 weeks. Caffeic acid (60 mg/kg, intraperitoneal) was injected daily for 4 weeks from 15th day. One day after the last injection, the mice were anesthetized and the ovaries were removed. Then, the morphometric changes of ovarian follicles were examined using hematoxylin-eosin (H&E) staining.
Results: The results showed that D-Galactose-induced POI significantly decreases the diameter of primary, secondary, and antral follicles (P<0.05). Administration of caffeic acid in the POI+CAF group significantly prevented the reduction of follicle diameter (P<0.05).
Conclusion: The results showed that caffeic acid can prevent the reduction of the diameter of ovarian follicles in POI model mice.
