The Potential of Cinnamon Extract (Cinnamomum burmanii) as Anti-insomnia Medication through Hypothalamus Pituitary Adrenal Axis Improvement in Rats.

OBJECTIVE: This study aimed to explore the efficacy of cinnamon extract as an anti-insomnia medication in experimental animals by evaluating the levels of hormones and neurotransmitters related to insomnia. MATERIALS AND METHODS: A total of 30 male Wistar rats were divided into six groups. Induction of insomnia in animal models was done by administration of p-chloro-phenylalanine (PCPA) compounds. Estazolam was administrated to the positive control group. Cinnamon extract administration was divided into 3 doses, namely: 25 mg/kg BW, 50 mg/kg BW and 100 mg/kg BW. Evaluation of the organ coefficient was conducted to evaluate drug toxicity to the organs. The enzyme-linked-immunoassay method assessed hormones and neurotransmitters in the serum and hypothalamus related to insomnia. RESULTS: There was a decrease in the adrenal coefficient in the cinnamon extract group compared to the PCPA group (0.011+0.001, P<0.05). In addition, there was a decrease in the corticotropin-releasing hormone, adrenocorticotropin hormone, and corticosterone levels in the serum of animals who received cinnamon extract. Our study found a dose of cinnamon extract of 50 mg/kg BW was the best dose to balance neurotransmitter levels in insomniac rats. CONCLUSION: The cinnamon extract increased serotonin and melatonin levels and decreased norepinephrine levels in the insomnia-induced group. Cinnamon extract has potential as an anti-insomnia medication through hypothalamus-pituitaryadrenal axis improvement and brain neurotransmitter regulation in an animal model of insomnia.

Blood glucose levels were measured before treatment and after treatment. Serum and urine parameters were determined. Antioxidant enzymes and lipid peroxide levels were determined in the kidney along with histopathological examination. RESULTS: The finding of this study showed that treatment APE at the dose of 200 mg/kg and 400 mg/kg ameliorated kidney hypertrophy index. SOD, catalase, and GSH activities significantly decreased in the kidney of STZ-diabetic rats compared to the normal control rats. Treatment with APE significantly decreased malondialdehyde level at the dose of 200 and 400 mg/kg BW. CONCLUSION: This study revealed evidence for improving diabetic retinopathy in male rats treated with Andrographis paniculata extract. APE significantly decreased oxidative stress activities in kidney of diabetic rats.

Lymphocyte Levels in Predicting the Outcome of COVID-19 Patient: A Prognostic Study from Single Center in Indonesia.

BACKGROUND: Several laboratory parameters have been linked to Corona Virus Disease 2019 (COVID-19), with lymphocytes being one of the most important. Lymphopenia is frequently linked to a worsening of clinical symptoms and an increased risk of death in COVID-19. This study aimed to determine the role of lymphocyte levels in predicting COVID-19 patient mortality. METHODS: This is a prognostic study that is conducted from March 1 to August 31, 2020. Data from medical records and laboratory findings of COVID-19 patients were used in the study. Patient distribution and complete blood count were among the information gathered. ROC curve analysis, bivariate analysis (Chi-Square and Mann Whitney), in addition to survival analysis (Kaplan-Meier) were used to analyze the data. RESULTS: In a total of 318 patients, 59 were non-survivors and 259 were survivors. Besides, a cut-off value of ?1460 cells/µL (P<0.05) was used for lymphocyte levels. Lymphopenia also has a 4.35-fold increase in the risk of mortality. Furthermore, the survival analysis revealed differences in the probability of survival within 30 days between COVID-19 patients with lymphopenia and those without (HR: 5.5722 (3.2509-9.5510), 95% CI; p<0.0001). A lymphocyte count of ?1460 cell/µL can increase the risk of death by fourfold. CONCLUSIONS: The findings of this study indicated a significant difference in outcome between lymphopenia and non-lymphopenia patients. Lymphopenia plays an important role in estimating COVID-19 patient mortality.

Inhibition of Receptor for Advanced Glycation End Products as New Promising Strategy Treatment in Diabetic Retinopathy.

BACKGROUND: Extensive intracellular and extracellular formation of advanced glycation end-products (AGEs) is considered a causative factor for vascular injury triggered by hyperglycemia in diabetes. The hyperglycemia will cause accumulation of AGEs, damage to pericytes, nerve growth factor (NGF), glial acid fibrillary protein (GFAP) and increase in vascular endothelial growth factor (VEGF). AIM: This study aimed to assess the efficacy of RAGE inhibition in suppressing the development and progression of diabetic retinopathy through modulation of the inflammatory pathway involving NGF, GFAP, and VEGF. METHODS: The design was in vivo experimental study. Thirty white rats were induced with Alloxan monohydrate. Rats were divided into 5 groups, normal, negative control, groups with an anti-RAGE dose of 1 µg/uL, the dose of 10 µg/uL and 100 µg/uL. After 4 weeks of treatment, HbA1c, NGF, and GFAP levels were measured using ELISA. Quantification of VEGF expression was done using the ImageJ® application. Data was expressed with mean ± SD. Independent T-test with ANOVA and Tukey's post hoc was done. RESULTS: RAGE inhibitors yielded a significant decrease in blood glucose and HbA1c levels. VEGF and RAGE expression were reduced in anti-RAGE groups in various doses. Inhibition of RAGE reduced the damage of retinal pericytes, by reducing GFAP and increasing NGF, and reduced the formation of new blood vessels, by decreasing VEGF expression, in diabetic retinopathy. CONCLUSION: Inhibition of receptor for advanced glycation end-products (RAGE) was effective in suppressing the development and progression of diabetic retinopathy.
