Chloroquine (CLQ) is a drug used in the novel coronavirus disease (COVID-19) and is widely used for the treatment of many inflammatory diseases such as malaria and rheumatoid arthritis. In this study, we aimed to reduce the destructive effects of hypoxia-induced inflammation and apoptosis in the intestinal mucosa of rats with CLQ applications. Methods: For this purpose, a total of 24 Wistar Albino rats were randomly divided into three groups;Group I: Control group (n=8), Group II: Hypoxia (n=8) and Group III: Hypoxia + CLQ (n=8). The control group was housed in plexiglass cages to keep the oxygen levels at 10% levels for 28 days, while the hypoxia and hypoxia+CLQ groups were housed in a normal atmospheric environment (21% O2), and the hypoxia+CLQ group was administered CLQ at a dose of 50 mg/kg every day for 28 days. At the end of the experiment, the intestinal tissues of the experimental animals, were extracted under the anesthesia and they were sacrificed. Results: As a result of histopathological evaluations, it was determined that CLQ applications showed healing properties on the histopathological effects induced by hypoxia in the intestine. While an increase in TNF-α expression was observed in the hypoxia group, a statistically significant decrease was detected in the hypoxia+CLQ group. In addition, Bax expression was found to be statistically significantly lower in the hypoxia+CLQ group when compared to the hypoxia group. On the contrary, it was observed that Bcl-2 expression was statistically significantly increased in the hypoxia+CLQ group compared to the Hypoxia group. Conclusion: We observed that hypoxia causes significant damage to the intestinal mucosa and triggers a severe inflammation that drives cells to apoptosis. Considering the curative effects of chloroquine on the intestinal mucosa, we suggest that this anti-inflammatory drug has a potential to use clinically to alleviate the deleterious effects of hypoxia in the intestine. © 2022.

However, in this procedure, infections, which often cause patient deaths, may develop due to catheter application. These infections are detected by monitoring the blood and/or catheter cultures of the patients. In the study, an analysis of the blood culture results of patients with CRF undergoing hemodialysis was performed in order to contribute to the epidemiological data. Methods: In this study, the culture results of patients who were thought to have catheter infection in the Hemodialysis Unit of SBU Samsun Training and Research Hospital between 2017 and 2020 were evaluated retrospectively. Blood cultures sent to the laboratory were incubated in the hemoculture organisms isolated from blood cultures were Pseudomonas aeruginosa (5.4%), Enterococcus faecalis (3.6%), E. coli , Enterobacter cloacae complex (3.6%), and Klebsiella pneumoniae (1.8%). Of the coagulase-negative staphylococci, 17 (70.8%) were resistant to penicillin and 18 (75.0) to methicillin. Of the S. aureus strains, 3 (50.0%) were found to be resistant to penicillin and 3 (50.0%) to methicillin. A statistically significant difference was found between CNS and S. aureus growth in blood cultures (p<0.05). Conclusion: High rates of bacteria were isolated from blood cultures of hemodialysis patients in our hospital. This result makes it necessary to draw attention to aseptic conditions in the hemodialysis process. Monitoring of blood and catheter cultures, detection of causative agents and evaluation of antibiogram results will play a key role in preventing infections and taking necessary precautions in hemodialysis patients.","PeriodicalId":35553,"journal":{"name":"Turk hijiyen ve deneysel biyoloji dergisi.

There were many biological attacks from the primitive ages when poisoned arrows were used to the use of anthrax spores in 2001 against USA. Although chemical attacks are not as deep-rooted as biological attacks, they have been used for a long time, but the period when they came to the stage of history was the 19th century with the development of the modern chemical industry. Chemical attacks caused injuries, permanent damage and death to many people especially during the period of World wars. The pandemic that can be caused by natural epidemic diseases is the spread of a factor or disease in a very wide area. With the spread of disease;panic, unrest and chaos environment occurs in the spreading area. Coronavirus (Covid-19), which causes the current pandemic, is the most recent example. Coronavirus out broke in Wuhan, China, and started to spread in China first, and then Iran, and had an impact on Italy as well as European continent and around the world with the American continent. It infected millions of people, hundreds of thousands of people died, and caused environmental, social, psychological and economic problems on a global scale. Recently, different pandemic processes related to influenza have been experienced, but states have not been able to demonstrate an effective and efficient defense against the new type of coronavirus since the necessary preparations were not made despite the death of millions of people. Since biological attack and natural epidemics have the same effects and characteristics, it is not possible to predict how the states will respond in a possible biological attack. As in the current pandemic process, the possible consequences that will arise when caught unprepared are doubtful. In this study, it is evaluated how biological agents and natural epidemics are similar to each other and how to take measures against a possible attack or a new disaster. © 2022,Turk Hijyen ve Deneysel Biyoloji Dergisi.All Rights Reserved.","PeriodicalId":35553,"journal":{"name":"Turk hijiyen ve deneysel biyoloji dergisi.

SARS-CoV-2 is a virus that can cause fever, dry cough, shortness of breath, anorexia, fatigue and sore throat, which can be transmitted through respiration and has started to spread around the world and has become a global problem. The disease caused by SARS-COV-2 has been named Coronavirus Disease 2019 (Covid-19) by the World Health Organization (WHO). According to the WHO, Covid-19 is a pandemic and it is stated that humanity has not experienced such an epidemic in the last hundred years. The coronavirus originated from bats and was transmitted to human through unknown animals in Wuhan province of China in December 2019. On January 2021, 96.658.420 confirmed cases and 2.092.062 deaths have occurred in the world. There is a growing need in the detection of SARS-CoV-2. A number of problems and difficulties are observed in the diagnosis and treatment of Covid-19. Chest tomography and molecular tests are used to detect SARS-CoV-2. The molecular techniques used are PCR-based and non-PCR-based methods. Usually detection of SARS-CoV-2 is based on PCR, but isothermal nucleic acid amplification tests have also been promising alternatives. Currently, qRT-PCR is a golden assay and it is widely used although many alternative assays have been developed for recent years. The current testing capacity and availability can not meet the unprecedented global demands for rapid, reliable and widely accessible molecular diagnosis. In addition, there is a need for a comprehensive strategy compare the molecular techniques used in the field.

In addition, measures implemented during the pandemic, such as isolation, lockdown and restricted mobility, adversely affected tuberculosis (TB) control programs in our country and around the world. In this study, it was aimed to investigate the effect of the COVID-19 pandemic on TB patients and TB control program in Mersin province. Methods: In this study, a total 6328 samples of 3731 patients with a preliminary diagnosis of TB, from Mersin University Hospital and Mersin tuberculosis dispensaries, between January 2019 and December 2020, were included. In the study, how much the number of samples decreased during the 2020 pandemic period, the number of patients diagnosed with TB, the change in the age distribution of the patients, and the number of control samples from the treatment follow-up of TB patients were examined. Results: In the study, a decrease of 42.2% in the number of patients and a decrease of 45.4% in the number of samples were observed during the pandemic period of 2020.The highest decrease in the number of patients by months were observed in March, April and May (respectively 44.2%, 67.2% and 69.8%) when the pandemic started in our country and the restrictions were applied intensively. During the pandemic period, a decrease of 28.2% was observed in the number of TB positive patients. While the mean age of TB positive patients was 53.5±16.2 in 2019, it decreased to 40.3±19.6 years in 2020, and the decrease in the mean age was statistically significant (p <0.001). When the age groups between years are compared;While the rate of patients over 65 years of age was higher in 2019, the rate of patients under the age of 18 was found to be higher in 2020 (p=0.003). In the study, control samples came during treatment follow-up from 73% of TB patients in 2019 and 52.9% in 2020. The rate of decrease in the number of patients with control samples from TB positive patients during the pandemic period was found to be statistically significant (p=0.021). Conclusion: The findings of our study revealed that the restrictions applied during the pandemic period adversely affected the diagnosis and follow-up of TB in our region. In addition, the decrease in the average age of TB patients and the tendency towards younger age and the increase in the number of positive patients under the age of 18 suggest that intra-familial transmission increased in this period. © 2022,Turk Hijyen ve Deneysel Biyoloji Dergisi,All rights reserved","PeriodicalId":35553,"journal":{"name":"Turk hijiyen ve deneysel biyoloji dergisi.
