The Protective Effect of Kentut Leaf Extract (Paederia foetida L.) on Gastric Histopathology in Escherichia coli-Infected Sepsis Mice Model
Full text linkSepsis, a severe medical condition, signifies the systemic immune response to infection, often leading to organ dysfunction and mortality. Escherichia coli is a significant contributor to sepsis cases, particularly in gastrointestinal disorders. This study aimed to investigate the histopathological changes in the gastric tissue of mice induced by Escherichia coli infection and evaluate the protective effects of kentut leaf extract (Paederia foetida L.). Histopathological analysis revealed distinct alterations in the gastric tissue among different treatment groups. While normal mouse treatment showed no significant changes, negative control (K-) and positive control (K+) groups exhibited inflammation and hyperemia of the gastric mucosa, characterized by necrosis, degeneration, and inflammatory cell infiltration. Treatment with kentut leaf extract (P1, P2, and P3) resulted in milder inflammation compared to controls, indicating a protective effect against gastric mucosal damage induced by Escherichia coli infection. This protective mechanism is attributed to the anti-inflammatory properties of saponins, flavonoids, and essential oils present in kentut leaf extract. These findings underscore the potential therapeutic benefits of kentut leaf extract in mitigating gastric mucosal injury associated with bacterial infection
Laboratory Detection of Toenail Onychomycosis Using Malt Extract Agar in Students
Full text linkOnychomycosis is a common nail disorder caused by dermatophytes, non-dermatophyte molds, and yeasts. Despite being more prevalent in older adults, it is increasingly reported among younger populations, including university students, due to lifestyle factors and communal exposures. Rapid and accurate diagnosis is critical for effective management, but conventional methods remain limited in sensitivity. This study aimed to evaluate the prevalence and etiological profile of toenail onychomycosis among university students using potassium hydroxide (KOH) microscopy and Malt Extract Agar (MEA) culture. A total of 98 students with clinical signs of onychomycosis provided toenail specimens. Direct microscopy examination with 20% KOH was performed, followed by culture on MEA at 28–30 °C for up to 21 days. Fungal isolates were identified based on macroscopic and microscopic morphology. Statistical analysis assessed associations between clinical features and culture results. KOH microscopy detected fungal elements in 59.2% of specimens, while MEA culture yielded growth in 63.3%. When combined, the overall prevalence of confirmed onychomycosis was 71.4%. Trichophyton rubrum was the most frequent isolate (35.5% of positive cultures), followed by non-dermatophyte molds such as Aspergillus and Fusarium, and yeasts including Candida albicans and Candida parapsilosis. Nail thickening and discoloration were significantly associated with culture positivity (p < 0.05). Onychomycosis is prevalent among university students, with MEA culture providing superior diagnostic yield compared to KOH microscopy alone. The identification of non-dermatophyte molds and yeasts underscores the importance of comprehensive diagnostic strategies for guiding effective treatment. Future studies should combine culture and molecular methods to enhance detection accuracy and clarify the clinical significance of emerging pathogens
THE EFFECT OF Paederia foetida L. EXTRACT ON LIVER WEIGHT OF MICE SEPSIS MODEL INFECTED WITH Escherichia coli
Full text linkSepsis is a critical medical condition characterized by a systemic immune response to in-fection, which can lead to severe organ dysfunction and mortality. Bacterial sepsis, par-ticularly caused by Escherichia coli, poses a significant risk due to its potential to harm tissues and organs, including the liver. The liver plays a central role in metabolic process-es and host defense during sepsis, making it a key organ of interest. This study aimed to investigate the effect of Paederia foetida leaf extract on liver weight in a mice sepsis mod-el. Mice were divided into six groups: normal control (N), negative control (K-) receiving distilled water, positive control (K+) receiving ciprofloxacin, treatment 1 (P1) receiving P. foetida extract at 100 mg/kg BW, treatment 2 (P2) receiving 300 mg/kg BW, and treat-ment 3 (P3) receiving 500 mg/kg BW. After 14 days of treatment, significant differences in liver weight were observed among the groups, with the highest mean and standard de-viation recorded in the P1 group (1.3750 ± 0.3932). Liver abnormalities, including swell-ing, lobular thickening, and weight increase, were identified, indicating the liver’s adap-tive response to toxic substances during sepsis. Interestingly, the normal control group exhibited higher liver weights compared to the treatment groups, possibly due to fatty substance accumulation within the liver tissues. These findings suggest that P. foetida ex-tract may influence liver weight changes in sepsis, potentially modulating metabolic and detoxification processes. Further studies focusing on histopathological and biochemical mechanisms are needed to clarify the therapeutic potential of P. foetida in managing liver dysfunction associated with sepsis
Study of Sperm Utilization in Female Drosophila melanogaster of bdp and btx Strains
Full text linkThis study investigates the patterns of sperm utilization in female Drosophila melanogaster of the bdp and btx strains through sequential mating with multiple males. The research was conducted as a descriptive observational study without experimental manipulation. Females of each strain were crossed with four different males in a specific order, with a two-day interval between each mating. F1 offspring phenotypes were recorded daily over a six-day period following the final mating. Data were analyzed descriptively and supported by somatic chromosome reconstruction to identify the male origin of each offspring. The results indicate that sperm utilization in D. melanogaster females occurs in both random and non-random patterns. Non-random utilization was observed when offspring were produced exclusively from the first male, with no contribution from subsequent males. For example, in the female btx × male N cross, only N female and N male offspring were produced, indicating that sperm from the first male was preferentially used. In contrast, random sperm utilization was evident in later matings, where offspring from multiple males appeared, suggesting that previously stored sperm remained viable and were used alongside or instead of sperm from later matings. These findings highlight the complexity of post-mating sexual selection in D. melanogaster, particularly the role of female sperm storage and utilization mechanisms. The ability of females to either favor the sperm of a particular male or mix sperm from several males may provide evolutionary advantages in terms of genetic diversity and offspring fitness. This study contributes to a better understanding of reproductive strategies and sperm competition in insects, with potential implications for broader studies in evolutionary biology and genetics
GAMBARAN MCV DAN MCH PADA PENDERITA TUBERKULOSIS PARU DI RSUD GAMBIRAN KOTA KEDIRI
Full text linkTuberkulosis paru merupakan masalah kesehatan yang dapat menyebabkan komplikasi. Salah satu komplikasi yaitu anemia, maka dari itu diperlukan pemeriksaan indeks eritrosit Mean Corpuscular Volume (MCV) dan Mean Corpuscular Hemoglobin (MCH) untuk mendiagnosis jenis anemia. Penelitian ini bertujuan mengetahui gambaran MCV dan MCH pada pasien tuberkulosis paru di RSUD Gambiran Kota Kediri. Metode yang digunakan adalah metode deskriptif observasional dengan desain cross sectional. Populasi berjumlah 76 pasien tuberkulosis paru di RSUD Gambiran Kota Kediri periode Januari-Desember 2021. Sampel berjumlah 43 orang sesuai kriteria inklusi dan eksklusi (purposive sampling) menggunakan data rekam medis. Hasilnya terdapat 33 orang memiliki nilai MCV rendah (mikrositik) dan 27 orang memiliki MCH rendah (hipokromik). Kadar MCV dan MCH rendah dikarenakan kekurangan asupan zat besi. Zat besi dapat berkurang disebabkan oleh infeksi bakteri Mycobaterium tuberculosis. Bakteri tersebut menyebabkan peradangan yang kemudian menghambat produksi hemoglobin dalam eritrosit. Akibatnya eritrosit tidak berfungsi maksimal untuk mengedarkan oksigen ke seluruh tubuh dan kualitas tubuh menjadi menurun. Pasien tuberkulosis paru di RSUD Gambiran Kota Kediri periode Januari-Desember 2021 sebagian besar mengalami anemia mikrositik hipokromik
The Influence of Strain Type and Female Age on the Receptivity of Female Drosophila melanogaster in Homogamous Crosses
Full text linkDrosophila melanogaster is a widely used model organism in genetic research due to its short life cycle and the presence of many genes homologous to those found in humans. It plays an important role in studies related to genetic inheritance, gene interaction, sex determination, and developmental genetics. One key aspect of its reproductive biology is female receptivity—the willingness of a female to accept mating—which is influenced by various internal and external factors. External factors include environmental conditions such as temperature and humidity, as well as male courtship signals like wing vibrations and chemical cues. Internal factors are mainly related to the female's sexual maturity and mating status. Generally, female receptivity increases with age after eclosion, reaches a peak, and gradually declines. This study investigates the impact of strain type and female age on receptivity in homogamous crosses of D. melanogaster, using two mutant strains: dp (with a wing mutation) and wa (with an eye color mutation). Receptivity was measured by the presence or absence of F1 offspring following crosses between males and females of the same strain, with females tested at different ages ranging from 10 to 60 hours after eclosion. The results indicate that strain type does not have a significant effect on female receptivity. In contrast, female age plays a clear role: individuals aged 30 years and older were more receptive and more likely to produce offspring. No significant interaction was found between strain type and age. These findings suggest that female receptivity in D. melanogaster is more strongly influenced by sexual maturity (as indicated by age) than by genetic differences between strains
BLOOD SMEAR EXAMINATION AND DIFFERENTIAL COUNT IN RATS WITH ESCHERICHIA COLI ESBL AND KLEBSIELLA PNEUMONIAE CARBAPENEMASE INFECTIONS
Full text linkSepsis is an irregular body response to severe infection, triggering uncontrolled inflammation that can lead to extensive tissue damage. It can progress to septic shock with multiple organ failure, resulting in death if left untreated. Laboratory examinations, such as leukocyte differential count in hematology, help understand the distribution pattern of white blood cells associated with health conditions. Laboratory research was conducted on mice injected with E. coli ESBL or K. pneumoniae carbapenemase. After 24 hours, observations were made on apoptosis in the spleen and liver of mice. Mouse blood was processed to count white blood cell types with a differential count. The results were analyzed to compare the control group with the bacterial infection groups of E. coli ESBL and K. pneumoniae carbapenemase. The research results indicate that the neutrophil count in the E. coli ESBL group is still within the normal range and lower (44.5±1.915%) compared to the K. pneumoniae carbapenemase group (55.75±8.342%). Similarly, the lymphocyte count in the E. coli ESBL group is within the normal range and lower (77.5±3.109%) compared to the K. pneumoniae carbapenemase group (91.25±7.588%). This highlights the crucial role of neutrophils and lymphocytes in responding to severe bacterial infections such as K. pneumoniae carbapenemase. Previous studies indicate neutrophilia and lymphocytopenia as markers of severe bacterial infections. Neutrophils are the primary defense against bacterial infections and can be rapidly recruited to the infection site, while specific infections can trigger prolonged neutrophil recruitment from hematopoietic tissues
The Correlation Between Widal Diagnostic Test, Total Leukocyte Count, and Platelet Count in Suspected Typhoid Fever Patients at RS Aura Syifa Kediri
Full text linkTyphoid 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
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
