Background:The present study was undertaken to investigate the hepatoprotective effect of Aloe vera against side effect of antituberculosis drug.Material and methods:Twenty-five rats will be divided into five groups, namely the control group (without any treatment), the group of rats treated with anti-tuberculosis drugs, and a group of rats were treated antituberculosis drugs and got Aloe vera extract at a dose of 40; 80; and 120 mg/kg body weight. Antituberculosis drugs are isoniazid and rifampicin a dose of 50 mg/kg body weight.Results:Antituberculosis treated group showed significantly increase levels of TNF-a, the percentage of NK cells and the number of Th17 cells compared with the control group (p < 0.05). All doses of Aloe vera reduce levels of TNF-a compared with the antituberculosis group (p < 0.05), although it has not yet reached levels comparable to the control group (p > 0.05). Aloe vera at first and the third dose lower the number of NK cells compared to the antituberculosis group, although it has not yet reached a significant difference (p > 0.05). The first dose of Aloe vera was significantly decreased the percentage of Th17 cells compared to the antituberculosis drug group (p < 0.05), although it has not yet reached levels comparable to the control group (p > 0.05).Conclusions:It was concluded that administration of Aloe vera can suppress the production of TNF-a and the percentage of Th17 cells as a result of antituberculosis drug administration. Thus, Aloe vera can be a useful alternative to natural materials in the successful treatment of tuberculosis through the inhibition of side effect.

Background: Covid-19 is a disease caused by acute respiratory syndrome due to corona virus 2. Patients with Covid-19 experience symptoms of severe shortness of breath resulting in death. The risk of death for Covid-19 sufferers will be greater if the patient has a history of comorbid diseases such as hypertension, diabetes mellitus, cardiovascular disease or kidney disease.Objective: The purpose of this study was to determine the relationship between comorbid diseases and the incidence of mortality in patients with Covid-19.Method: Research design using descriptive analytic. The research population was all Covid-19 sufferers who were treated at Mojowarno Christian Hospital (RSK) during 2021 totaling 450 sufferers. The research sample was 212 respondents with a sampling technique using systematic random sampling. The data was obtained from the medical records of Covid-19 patients who were treated at the Mojowarno Hospital. Statistical test using chi square and odds ratio with a significance level of P <0.05. Results: The results of the study found that comorbid diabetes mellitus showed a result of P: 0.000, meaning that there was a relationship between comorbid diabetes mellitus and the incidence of mortality in patients with Covid-19. Comorbid kidney disease shows a P value: 0.003, meaning that there is a relationship between comorbid kidney disease and the occurrence of mortality in Covid-19 sufferers. Comorbid heart disease results obtained P: 0.089, meaning that there is no relationship between comorbid heart disease and mortality in patients with Covid-19. Hypertensive comorbid disease on mortality with a P value: 0.134 meaning that there is no relationship between hypertension comorbid disease and the risk of mortality in patients with Covid-19. Conclusion:Covid-19 sufferers who have comorbid diabetes mellitus cause greater mortality. This is because diabetes mellitus can cause a cytokine storm which plays a role in increasing the severity of COVID-19 sufferers so that it often causes death.

Introduction: Aloe vera has anti-bacterial ability against Gram-positive and Gram-negative bacteria; however, anti-bacterial study, especially in multidrug resistant strain of Mycobacterium tuberculosis, has not been evaluated yet. This study aims to determine the potential of Aloe vera as an antituberculosis against drug-resistant strains of tuberculosis. Method: Stages of research include the production of ethanol extract of Aloe vera, then testing the phytochemicals (identification of alkaloids, steroids/triterpenoids, anthraquinone, flavonoids, saponins, tannins) and chemical content testing by thin layer chromatography (TLC). The anti-bacterial test for Mycobacterium tuberculosis was performed on the Lowenstein Jensen media. Results: Test results showed the qualitative identification, and TLC contains alkaloids, steroids/triterpenoids, anthraquinone, flavonoids, saponins, and tannins. Antioxidant activity against DPPH radical shows an IC50 value of 6927.133 ppm. Test of anti-bacterial activity to Mycobacterium Tuberculosis H37Rv and MDR TB strains HE (resistant to INH and Ethambutol), and SR (resistant to streptomycin and Rifampicin) showed inhibition ranging concentration of 50 mg/mL in all extracts as well as to test the sensitivity, a sensitive start to a concentration of 50 mg/mL in all extracts. Conclusions: Aloe vera contains alkaloids, steroids/triterpenoids, anthraquinone, flavonoids, saponins, and tannins that act as antioxidants and antituberculosis against strains of Mycobacterium tuberculosis that are not resistant and resistant to anti-tuberculosis drugs.
