Objective: Coronavirus disease-2019 (COVID-19) was declared a pandemic in March 2020. As the number of cases increased, the infection emerged as a multi-systemic disease. Respiratory, cardiac, hepatic, urinary, circulatory, gastrointestinal systems and finally skin may be the target organs of COVID-19. The aim of this study was to evaluate the cutaneous signs of COVID-19 and their effect on the patients' prognosis. Material and Methods: A total of 192 hospitalized COVID-19 cases, between May 2021 to July 2021 were included in the study. The length of stay (LoS) of the patients were recorded. Hospitalization and discharge decisions and all treatments of the patients were determined at the discretion of the treating physician according to the pandemic guidelines of the Ministry of Health. Fever, fatigue, cough, dyspnea, myalgia, anosmia, and headache were considered COVID-19 symptoms. Results: Dermatological manifestations were seen in 10 cases. LoS in the group with dermatological findings was shorter than the group without dermatological findings and the difference was statistically significant between the groups. Discharge of the patients was the endpoint of the study. Conclusion: Our multicenter study suggests that patients with cutaneous findings usually do not have classical symptoms for COVID-19 and have a shorter LoS. © 2022 OrtadogŸu Reklam Tanitim Yayincilik Turizm Egitim Insaat Sanayi ve Ticaret A.S..

Glutathione is the important antioxidant agent that is used for body detoxification system. Because of the fact that ıt is crucial for protecting health. A feeding trial was conducted to evaluate the effect of natural additives such as live yeast culture Saccharomyces cerevisiae (SC) and microalgae Spirulina platensis (SP) on the glutathione and leukocytes counts of rabbits. Forty male New Zealand white rabbits, aged 5-6 weeks, were studied in 4 groups. Treatments were control group, SC (added 3 g/kg diet), SP (added 5% of the diet) and, SC and SP (added 3g/kg diet and added 5% of the diet) respectively. The experiment lasted for 90 days and the blood samples were obtained by ear venipuncture on the 90th day. In conclusion, according to the results of this study, although not statistically significant, supplementing rabbit with S. cerevisiae or S. platensis had increased on glutathione values. Glutathione tend to be positively correlated with the addition of SC or SP. No significant difference in white blood cell counts was evidenced, even if lymphocyte counts tended to increase and neutrophil counts to decrease in rabbits fed SC or SC+SP. The determination of biological consequences (antioxidant potential, resistance to diseases, and improvement of nutritional status) requires further investigations.

Transplantasyon; Temel Tıbbi Bilimler, Moleküler Tıp, Genetik ve İmmünolojiden klinik uygulamalardan destek alan multidisipliner bir tıp dalıdır. Temel bilimlerdeki başarılı çalışmaların kliniğe uygulanması, klinikte karşılaşılan sorunların da, oluşturulan deneysel hayvan modellerinde irdelenmesi, elde edilen bilgilerin klinik uygulamalara aktarılması; diğer deyişle tecrübelerin “Translational” özellikli olması günümüz transplantasyon çalışmalarında bir gerekliliktir. İmmün sistemin bileşenlerinin ve reaksiyonlarının iyi bilinmesi, hücreler arası ilişkilerde greftin reddi ya da kabul edilmesinin şartlarını doğru anlamak ve uygun laboratuvar yöntemleri ile klinik durumun aydınlatılması transplantasyonda stratejik önemdedir. Bu nedenle, klinik transplantasyon çalışmaları yapanlar temel bilimler bilgileri ile de donanımlı olmalıdırlar. Multidisipliner bir dal olma bilinci ile yapılan klinik transplantasyon çalışmalarında başarı yakalanmaktadır. Laboratuvardan Kliniğe Transplantasyon kitabımızda tüm yönleri ile transplantasyonun organizmaya etkileri ve bunların klinik sonuçlarını, çalışmalarımızın ışığında sunmayı ve tartışmayı hedefledik.
