Abstract

Refill Drinking Water Depots (DAMIU) have become a popular source of drinking water in Indonesia due to their affordability and accessibility. However, concerns about hygiene and microbial contamination persist, particularly in areas with limited health oversight. This study aimed to evaluate the microbiological quality of refilled drinking water in Kediri City by detecting the presence of Escherichia coli as an indicator of fecal contamination. A descriptive, cross-sectional design involving 22 depots selected based on hygiene criteria was employed. Microbiological analysis used the Most Probable Number (MPN) method, with confirmatory tests including IMViC and Eosin Methylene Blue (EMB) media. The results showed that 20 of 22 depots met the microbiological safety standard of 0 CFU/100 mL for E. coli as set by the Indonesian Ministry of Health and national standards (SNI 3554:2015). Two samples (5 and 7) tested positive for E. coli, likely due to environmental contamination, inadequate sanitation, and poor water handling practices. The positive samples demonstrated typical E. coli characteristics in IMViC (++-+) and gas formation in BGLB media. This study underscores the importance of routine surveillance, public health regulation enforcement, and improved hygiene practices in refilled water depots. Ensuring the microbiological safety of refilled drinking water is essential to prevent waterborne diseases such as diarrhea. The findings call for enhanced collaboration between local health offices and depot operators to maintain clean and safe drinking water standards across communities.

Abstract

Gastroenteritis, a prevalent digestive disorder caused by various pathogens including Escherichia coli, remains a global health challenge with significant morbidity and mortality, particularly in low-income countries. The spleen, as a critical immune organ, is often compromised during systemic infections. Peperomia pellucida (L.) , a traditional medicinal herb, is known for its antimicrobial, anti-inflammatory, and antioxidant properties. This study investigates the histopathological effects of P. pellucida leaf ethanol extract on spleen tissue in mice induced with E. coli to model bacterial gastroenteritis. Thirty male Swiss mice were divided into six groups (n=5): normal control, negative control (aquades), positive control (Yakult), and three treatment groups receiving P. pellucida extract at 100, 300, and 500 mg/kg BW. After seven days of pretreatment, mice were orally infected with E. coli (1×10⁶ CFU/mL) for another seven days. Spleen tissues were harvested, fixed, and stained with hematoxylin-eosin for histopathological evaluation focusing on degeneration, necrosis, and PMN infiltration. Statistical analysis was performed using ANOVA followed by LSD tests. The highest dose of P. pellucida extract (500 mg/kg BW) significantly reduced spleen tissue damage, showing decreased degeneration (9.08%), necrosis (6.05%), and PMN infiltration (18.45%) compared to lower doses. The effect was comparable to the positive control. The ethanol extract of P. pellucida demonstrates a dose-dependent protective effect on spleen histopathology in E. coli-induced gastroenteritis in mice, supporting its potential as a natural antiseptic agent.

Abstract

Gastroenteritis, a widespread condition characterized by inflammation of the stomach and intestines, poses significant health challenges globally. Conventional treatments primarily focus on symptomatic relief and do not address the underlying gastric mucosal damage. Peperomia pellucida L., a medicinal plant known for its anti-inflammatory and antioxidant properties, has been suggested to possess gastroprotective effects. This study aims to evaluate the histopathological effects of P. pellucida L. on gastric protection in a mouse gastroenteritis model. Male Swiss mice were divided into six groups, receiving different treatments, including the ethanol extract of P. pellucida at varying doses (100, 300, and 500 mg/kgBW), followed by induction of gastroenteritis with Escherichia coli. Histopathological analysis was conducted to observe tissue damage across the treatment groups, including necrosis and cell degeneration. The results revealed that P. pellucida L. exhibited significant gastroprotective effects, particularly at a dose of 500 mg/kgBW, reducing gastric mucosal necrosis and inflammation compared to the control groups. The plant’s secondary metabolites, including flavonoids, tannins, saponins, and alkaloids, contributed to the observed protective effects by enhancing mucus production, reducing gastric acidity, and promoting tissue repair. These findings suggest that P. pellucida L. could be an alternative treatment for gastroenteritis and related gastric conditions, offering a natural approach to managing gastric inflammation and mucosal protection.

Abstract

Cerebrovascular accident (CVA) is a major cause of morbidity and mortality, often requiring intensive care unit (ICU) treatment. Patients with CVA are at high risk for secondary infections, which commonly lead to the use of antibiotics. This study aimed to evaluate the patterns and rationality of antibiotic use in CVA patients treated in the ICU of a regional hospital using the Gyssens method. A retrospective observational study was conducted involving 30 CVA patients who received antibiotics during their ICU stay. Data collected included patient demographics, comorbidities, types of antibiotics used, route of administration, combination patterns, and evaluation of prescription rationality based on the Gyssens criteria. The most frequently used antibiotic class was third-generation cephalosporins (60%), with ceftriaxone being the most prescribed (46.7%). All antibiotics were administered intravenously. Combination therapy was used in 20% of cases. Based on Gyssens categorization, only 33.3% of prescriptions were considered rational (category 0). The remaining 66.7% were irrational, including delayed initiation or discontinuation (13.3%), incorrect dosing (16.7%), unnecessarily broad-spectrum (10%), and no indication (6.7%). The study highlights a substantial proportion of irrational antibiotic use in ICU CVA patients, mainly due to suboptimal timing, dosing errors, and unnecessary broad-spectrum antibiotics. These findings underline the importance of antimicrobial stewardship and routine rationality assessments to ensure optimal antibiotic use and patient outcomes.

Abstract

The demand for aphrodisiac use is substantial, however, many marketed herbal products contain synthetic drugs, underscoring the urgent need for safer natural therapeutic alternatives. This study aimed to evaluate the aphrodisiac potential of ethanol extract of Elephantopus scaber (Tapak Liman) leaves on serum testosterone levels and testicular histology in male Wistar rats. The extract was obtained through maceration with 70% ethanol and subjected to phytochemical screening, which revealed the presence of flavonoids, tannins/phenolics, and triterpenoids. Healthy male Wistar rats were divided into five groups: normal control, negative control, positive control (sildenafil), and two treatment groups receiving 100 mg/kg BW and 200 mg/kg BW of the extract for 21 days. Serum testosterone levels were measured using ELISA, while histological examination focused on the diameter of seminiferous tubules. The results demonstrated that the 200 mg/kg BW dose significantly increased testosterone levels (209.41 ± 0.62 ng/dL) compared with the negative control (120.32 ± 1.55 ng/dL) and restored the diameter of seminiferous tubules (220.56 ± 4.98 µm) close to normal conditions (225.30 ± 5.12 µm). The 100 mg/kg BW dose produced a moderate effect, while the positive control also showed notable improvement. The observed increase in testosterone and recovery of seminiferous tubule diameter indicate that the extract enhances spermatogenic activity and testicular function. In conclusion, the ethanol extract of E. scaber leaves at 200 mg/kg BW demonstrated significant aphrodisiac activity through hormonal stimulation and improvement of testicular histology, suggesting its potential as a natural agent to support male reproductive health.

Abstract

Kentut leaves (Paederia foetida L.) are a type of 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 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 that there is 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/kgBW. 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.

Abstract

Sepsis is a critical health concern characterized by organ dysfunction due to uncontrolled host reactions to infections. The prevalence of microorganisms causing sepsis varies, with Gram-positive bacteria and fungal sepsis gaining significance. Sepsis often leads to acute kidney injury (AKI), and its association with sepsis is known as sepsis-associated AKI (SA-AKI). The "Daun Kentut" plant, known for its diverse bioactive compounds, has shown potential in combating inflammation and oxidative stress. In this study, histopathological changes in mouse kidneys induced by Escherichia coli were investigated. Hemorrhage was the primary change observed. Dehydration caused by E. coli infection potentially led to kidney injury through hormonal responses. The plant extract's anti-inflammatory potential, attributed to compounds like saponins and flavonoids, was also explored. The study emphasizes the need for understanding sepsis-related kidney damage and suggests possible preventive strategies using natural compounds.
