Abstract

Severe acute respiratory syndrome coronavirus (SARS-CoV) is an etiologic agent of respiratory disease that has a mortality rate of 10%. IL-1 actively participates in the inflammatory response to infection. SARS-CoV-2 appears to act on the activation and maturation of IL-1?, which in turn activates other proinflammatory cytokines, such as IL-6 and TNF-. Therefore, IL-1? is part of the cytokine storm generated by coronavirus infection. Elevated levels of the IL-1 receptor antagonist (IL-1Ra) in severe cases of COVID-19, and this marker have been associated with increased viral load, loss of lung function, lung damage, and risk of death. In addition, there is an increase in IL-1? levels in patients with severe COVID-19, and this is strongly associated with lung injury. IL-1 levels are associated with the virulence of the process, and significantly higher serum levels have been observed in severe symptomatic SARS-CoV-2 cases than in mild cases or in those infected with the 2003 SARS-CoV coronavirus or 2012 MERS coronavirus.

Abstract

Monosodium glutamate (MSG) biasanya berbentuk kristal halus dan berwarna putih. Senyawa MSG dibuat melalui proses fermentasi dari bahan dasar pati (gandum) dan gula molasses (tetes tebu) yang diberi nama sebagai garam natrium dan asam glutamat. Pemberian MSG selama induk mencit bunting bersifat embriotoksik. Penelitian ini bertujuan untuk mengetahui efek toksik MSG pada perkembangan embrio selama masa organogenesis. Penelitian pemberian MSG terhadap mencit dimulai pada kebuntingan hari ketujuh yaitu pada tahap organogenesis. Perlakuan dosis MSG yang diberikan adalah dosis 528 mg/kg BB, 696 mg/kg BB, dan 872 mg/kg BB. Peubah yang diamati dalam penelitian ini adalah jumlah fetus hidup atau mati dalam rahim pada kebuntingan hari ke-18, di samping morfologi fetus, bobot fetus dan perkembangan tulang rangka fetus. Hasil penelitian menunjukkan bahwa pemberian MSG yang dilakukan secara terus menerus sejak kebuntingan hari ke-7 hingga 16 membuat MSG tersebut masuk ke dalam tubuh induk mencit yang tidak memiliki kemampuan untuk menetralisir dan mendetokfikasi senyawa-senyawa kimia sehingga terakumulasi pada embrio mencit. Zat-zat tersebut mencapai embrio melalui pembuluh darah dan memengaruhi perkembangan fetus mencit. Penelitian ini menunjukkan bahwa ada pengaruh MSG terhadap perkembangan fetus mencit (Mus musculus) selama periode organogenesis di antaranya yaitu kecacatan pada mata (mikropthalmia dan anoftalmia), hidrosefalus ringan, jumlah metakarpal, jumlah metatarsal, dan ruas cervikal vertebrae tidak sama panjang. Abnormalitas perkembangan fetus mencit selama periode organogenesis meningkat sejalan dengan peningkatan dosis MSG yang diberikan dan bervariasi antar perlakuan. Semakin tinggi dosis MSG yang diberikan pada induk mencit bunting, maka semakin sedikit jumlah fetus yang hidup. Dapat disimpulkan bahwa MSG memengaruhi perkembangan fetus mencit selama masa organogenesis.

Abstract

Typhoid fever is an acute systemic infectious disease that is related to poor personal hygiene and environmental sanitation. The diagnosis of typhoid fever is established through laboratory examinations, including serological, hematological, and bacteriological tests. This research aims to determine the correlation between the Widal diagnostic test and the total leukocyte count and platelet count in suspected typhoid fever patients at RS Aura Syifa Kediri. The study design used in this research is quantitative descriptive analysis with a cross-sectional approach. The data was collected retrospectively from secondary sources, specifically medical records of patients from August 1, 2021, to March 31, 2022, at RS Aura Syifa Kediri. The total population comprised 157 patients, and a purposive sampling method was used to select 41 patients who met the inclusion and exclusion criteria. The statistical analysis using the Spearman correlation test resulted in p-values ≥ α = 0.05 for the following correlations: Widal test O with leukocytes (0.538 ≥ 0.05), Widal test H with leukocytes (0.915 ≥ 0.05), Widal test O with platelets (0.476 ≥ 0.05), and Widal test H with platelets (0.965 ≥ 0.05). These findings indicate that there is no significant correlation between the Widal test O and H with the platelet count in patients with typhoid fever. Therefore, it can be concluded that there is no significant relationship between the Widal test O and H results and the platelet count in typhoid fever patients.

Abstract

The leukocyte count examination in tuberculosis infection serves to monitor the inflammation caused by Mycobacterium tuberculosis. An increasing leukocyte count can lead to complications such as pleuritis. The purpose of this study was to determine the total leukocyte count of pulmonary tuberculosis patients at RSUD Gambiran, Kediri City, based on gender and age. This research was a descriptive retrospective study. Data analysis was conducted using Microsoft Excel and presented in the form of tables and diagrams. The results of this study showed that pulmonary tuberculosis infection was more prevalent in males, with 26 individuals (62%) affected. In terms of age groups, the highest infection rate was in the 21-60 years age range, with 30 individuals (71%) affected. As for leukocyte count elevation (leukocytosis), it was more commonly observed in males with a count of 14.57 µL. In terms of age groups, leukocytosis was frequently observed in the 21-60 years age range, with a count of 48.66 µL. Out of the 42 samples, 19 individuals had a normal leukocyte count, while the remaining 23 individuals experienced leukocytosis. From the results of the study, it can be concluded that not all pulmonary tuberculosis patients experience leukocytosis; some patients maintain a normal leukocyte count.

Abstract

Escherichia coli is a pathogenic bacterium that causes infectious diseases in the digestive tract and can produce Lipopolysaccharide (LPS), including lipid A. Exposure to endotoxins in lipid A, can cause systemic effects, such as sepsis, which can lead to clinical manifestations and even death. Daun Kentut (Paederia foetida L.) is one of the herbal plants containing bioactive compounds that can inhibit the growth of E. coli bacteria. The aim of this research is to determine the effective concentration of daun kentut leaf extract to inhibit E. coli growth. This study is an experimental research using maceration extraction method and antibacterial disc diffusion method with 3 repetitions at concentrations of 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 100%, negative control (aquadest), and positive control (ciprofloxacin) conducted from March to April 2023 in the Microbiology Laboratory of Kadiri University. The observation results of inhibition zones in each treatment varied. The presence of these inhibition zones is due to the presence of secondary metabolite compounds in daun kentut leaf extract that have antibacterial activity, such as inhibiting protein synthesis mechanisms, causing damage to cell wall permeability, and ultimately leading to bacterial cell lysis and death. The statistical analysis using the One Way Anova test with a P-value of 0.05 shows that each variable has significant differences and effects. Thus, it can be concluded that the effective extract variation is the 100% concentration because, in this study, the 100% concentration has an inhibition zone of 26.72 mm and is classified as very strong in inhibiting E. coli bacteria.

Abstract

Kentut leaves (Paederia foetida L.) are a medicinal plant that can be used as a preventative medicine against sepsis. This plant contains secondary metabolite compounds such as alkaloids, flavonoids, triterpenoids, saponins, and other active compounds. This research aims to to determine the influence and effective dosage of Kentut leaf extract as a preventive measure against IL-6 expression in the livers of mice in a sepsis model injected with E. coli. The method used was a Completely Randomized Design (CRD). The study involved 24 white male mice divided into 6 groups. Data analysis was performed using One way ANOVA. The average values of IL-6 expression in the mouse livers for each group are as follows: KN at 7.09%±0.06; K+ at 26.36%±0.02; K- at 72.60%±0.05; PI (100mg/kgBW) at 71.04%±0.04; PII (300mg/kgBW) at 62.22%±0.02; and PIII (500mg/kgBW) at 40.92%±0.01. The research results indicate an influence of kentut leaf extract as a preventive measure against IL-6 expression in the livers of mice in the sepsis model injected with E. coli, with a significance value of 0.000 or p-value < 0.005. The effective dosage of kentut leaf extract as a preventive measure against IL-6 expression is the PIII dosage of 500mg/kg BW. The anti-inflammatory mechanism in sepsis is thought to be caused by the presence of flavonoids, alkaloids, phenolic acids, and terpenoid compounds. The most likely anti-inflammatory mechanism is believed to involve flavonoids inhibiting cyclooxygenase (COX) and lipoxygenase (LOX) enzymes involved in the synthesis of inflammatory mediators such as prostaglandins and leukotrienes, which can trigger IL-6 production.
