Abstract

Abstract Introduction Depression is believed to be a disorder in which an increase in serotonin activity in the brain. This has implications for the development of various antidepressant drugs that work to increase serotonin levels, by inhibiting serotonin reuptake. However, management with antidepressants is still believed to be not optimal, there are still various problems that have not been able to be solved only by increasing serotonin levels in the brain. Therefore, it is necessary to do further exploration to find out other possible pathophysiology of depressive disorders. This study intended to explore the role of apoptosis of neuronal cells in the prefrontal cortex to answer the hypothesis that depression was not only caused by increased serotonin levels but also there was a role of dead neuronal cells in the prefrontal cortex which will trigger the body's homeostatic efforts to compensate by increasing serotonin levels. Methods A total of 30 male Wistar rats (200 ± 20 g) were obtained from Eureka Research Laboratory (Palembang, Indonesia). Experimental animals were placed in cages under controlled conditions (12 hours of light / dark cycles with temperatures of 22 ± 1˚C and humidity of 40-60%), fed and drank ad libitum. Experimental animals with depression model were induced using Chronic Mild Stress (CMS). CMS procedures were performed with mild stressors such as repeated cold stress (4 ° C), space reduction in the homecage, changed cages and social interaction with other animals of the CMS group. To assess wether animal were being depression or not, the animal were tested using Forced Swimming Test (FST). After induction, rats were randomly divided into two groups which each contained 15 animals: the normal control group (not induced CMS) and the CMS group (negative control). Furthermore, the animal model was performed perfusion to maintain organ when evacuation was done, cell damage did not occur. To evaluate cell organ, immunohistochemistry examination and ELISA examination was performed. All data are presented as mean ± standard deviation and all statistical analyzes are performed with the SPSS 25 (IBM) program. Result This research showed that CMS animal model has a greater duration of immobility than the normal group and serotonin level in CMS animal models decreased almost threefold compared to the normal group. In addition, there were increased expression of caspase-3 indicates that more neuronal cells suffered from apoptosis. So, in this research, it was clearly stated that in depressive disorder, there were elevation of neuronal cell apoptosis in the prefrontal cortex. Conclusion Neuronal cell apoptosis in the prefrontal cortex plays a role in the pathophysiology of depression through activation of negative feedback on serotonin production.

Abstract

The Secretion of IFN-Gamma and IL-2 After ESAT-6-CFP-10 Fusion Antigen Stimulation in Active and Latent TB Patients. This study held to discover how immune responses work and to know the pathogenesis of active TB and latent TB patients. This study used PBMC to stimulate T Cells with ESAT-6 and CFP-10 antigen fusion, and measure the level of IFN-gamma and IL-2 with ELISA antibody sandwich (U-Cytech). 16 ml of blood were drawn to 5 tubes. ESAT-6 CFP-20 inducted one tube with QuantiFERON for IFN-gamma assay. The other four tubes were PBMC isolated using Ficoll-Paque, and pre-incubated with stimulation of ESAT-6 CFP-10 fusion antigen for 24-72 hours at 370 C and measured using T-Spot and ELISA reader. We got from this study that there are no significant differences in IFN-gamma levels for both groups with active TB and latent TB. Measurement of IL-2 levels showed significant differences between the two group.

Abstract

COVID-19 is a contagious acute respiratory disease caused by the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) virus. Changes in some laboratory markers such as absolute lymphocyte count and quantitative CRP in COVID-19 can be associated with the course and clinical phases of the patient whose results can be useful in grading and predicting the severity of COVID-19 disease. This study aims to determine the correlation between absolute lymphocyte count and quantitative CRP on the severity of COVID-19. This study was an observational correlative analytic study with a cross sectional design. The research was conducted in all COVID-19 treatment isolation wards at RSMH Palembang from March 2021 to April 2021 with the research subjects being patients with confirmed cases of COVID-19 with various degrees of disease. Routine blood tests of absolute lymphocyte counts and quantitative CRP were performed at the Clinical Pathology Laboratory of RSMH Palembang. The statistical analysis of the correlation test with Spearman for numerical data was not normally distributed, and Gamma for categorical ordinal data was followed by a regression test to determine the prognostic value of the two parameters. Samples obtained were 83 patients, namely 24 patients (28.9%) mild degree, 40 patients (48.2%) moderate degree, 10 patients (12%) severe degree and 9 patients (10.8%) critical degree. The correlation between the absolute lymphocyte count and quantitative CRP obtained the correlation coefficient value r = – 0.525. The correlation between the absolute lymphocyte count and the degree of COVID-19 disease obtained a correlation coefficient of r = – 0.605, while the correlation between the quantitative CRP value and the degree of disease was obtained r = 0.875. Based on the prognostic test, the absolute lymphocyte count (cutoff point of 1,157 cells / mm3) was obtained with a sensitivity of 68.4% and a specificity of 68.75%. Meanwhile, quantitative CRP with a cutoff point of 77.5 mg/L obtained a sensitivity of 89.4% and a specificity of 89%. The absolute lymphocyte count has a strong negative correlation with the quantitative CRP value and the disease degree in COVID-19, while the quantitative CRP value has a positive correlation with a very strong degree. Thus these two parameters can be used as predictors of disease severity, however, the quantitative CRP value can be an independent prognostic marker or a single predictor of the severity of COVID-19 disease.
