Abstract

Ascaris lumbricoides is nematode which often infest human in the world. The infestation of A. lumbricoides in the human will trigger the formation of Th2 immune responses through increased interleukin-4 released by innate immune cells. Th2 immune response generates B lymphocyte cells to produce IgE antibodies to eliminate A. lumbricoides. Therefore, IL-4 is a marker of Th2 immune response. The purpose of this study was to determine the prevalence of ascariasis and an increase of IL-4 in planters infested with A. lumbricoides as a marker of Th2 immune response. Our study was observational analytic with cross sectional design. 230 planters who were willing to be involved in the study gave stool samples for the diagnosis of ascariasis. 20 people who were positive for ascariasis and 20 people who were negative selected randomly for blood plasma samples. IL-4 levels in blood plasma were measured using ELISA. Differences in IL4 levels between positive and negative ascariasis were analyzed by the Mann Whitney statistical test with p value ≤ 0.05. The prevalence of ascariasis among planters in rural area of Jember was 16,52% which was included low prevalence. Univariate analysis showed that the mean and median levels of IL-4 ascariasis were greater than those of healthy planters. Mann Whitney test results showed that there were differences in levels of IL-4 between ascariasis and healthy planters (p≤0.05). Increased levels of IL-4 in planters with ascariasis indicate that A. lumbricoides infection triggers the formation of Th2 immune response as a mechanism for eliminating A. lumbricoides. Keywords: Interleukin-4, A. lumbricoides, Th2 immune response.

Abstract

Sel darah putih merupakan sel yang sensitif terhadap infeksi dan perubahan lingkungan. Penelitian ini menyelidiki efek paparan jangka panjang terhadap medan Extremely Low-Frequency (ELF-MF) pada 50 Hz dan 100 μT terhadap komposisi leukosit mencit BALB/C, dengan fokus pada neutrofil, monosit, dan limfosit. Dua puluh empat tikus BALB/C jantan dibagi menjadi kelompok kontrol, 15 hari, dan 30 hari paparan, dengan paparan intermiten setiap hari selama 2 jam. Jumlah leukosit dianalisis menggunakan ANOVA satu arah.Hasilnya menunjukkan perubahan signifikan pada populasi leukosit. Jumlah neutrofil meningkat secara progresif setelah 30 hari, yang menunjukkan adanya potensi respons inflamasi. Tingkat monosit menunjukkan dua tahap, awalnya menurun pada hari ke-15 lalu melonjak 82,3% pada hari ke-30, yang menunjukkan aktivasi kekebalan adaptif. Sebaliknya, jumlah limfosit tetap stabil hingga hari ke-15 tetapi menurun secara signifikan sebesar 2,14% pada hari ke-30, yang berpotensi mencerminkan modulasi kekebalan yang diinduksi oleh stres.Temuan ini menyoroti radiasi ELF-MF dapat mengubah dinamika leukosit, kemungkinan dimediasi melalui jalur stres oksidatif dan respons inflamasi yang berkepanjangan. Perubahan ini menggarisbawahi pentingnya penelitian lebih lanjut tentang implikasi kesehatan jangka panjang dari paparan ELF-MF, mengingat meningkatnya prevalensi radiasi elektromagnetik di lingkungan modern.

Abstract

Cigarette smoke exposure is the major risk of chronic obstructive pulmonary disease, the third cause of death worldwide. Inhaled smoke triggers oxidative stress resulting in airway epithelium thickening and cilia shortening. Shallot (Allium cepa L.) peel contains flavonoid which can neutralize oxidative stress. This study aims to determine correlation between shallot peel infusion (SPI), bronchus epithelium thickness, and cilia length in cigarette smoke-induced rats; and establish maximum effective dose of SPI. Rats were divided into normal; cigarette; SPI 125, 250, 500, 1,000, 2,000 mg/kgBW groups. Two hours after administration, rats were exposed to cigarette smoke 2 cigarettes/day for 28 days. Hematoxylin-eosin-stained bronchus was observed and variable measurements were carried out. Comparation tests of epithelium thickness and cilia length between normal and cigarette group showed significant difference (p<0.05); Pearson coefficient between SPI dose and epithelium thickening was -0.614, Spearman coefficient between SPI dose and cilia length was 0.860; and maximum effective dose to prevent bronchus epithelium thickening and cilia shortening are 1,275.4 mg/kgBW and 1,325.8 mg/kgBW. In conclusion, the higher the SPI dose, the lower epithelium thickness, the higher cilia length. Maximum effective dose of SPI to prevent bronchus epithelium thickening and cilia shortening are 1,275.4 mg/kgBW and 1,325.8 mg/kgBW.

Abstract

Diazinon, an organophosphate pesticide, is used extensively in agricultural sector. Consumption of agricultural products containing diazinon residue may lead to harmful health consequences. Among these is nephrotoxicity, which includes lipid peroxidation, that can damage the kidney. Flavonoids in shallot peel can scavenge free radicals, inhibit necrosis, and activate bone marrow-derived cells for cell regeneration. This study aimed to determine the correlation between shallot peel infusion (SPI) dose and kidney damage amelioration to establish the maximum effective dose of SPI to ameliorate kidney histopathological damage in diazinon-induced rats. This study was performed at the Pharmacology Laboratory, Faculty of Medicine, University of Jember, Indonesia, in April 2021, on 35 rats that were divided into 7 groups—normal, diazinon, and five treatment groups. Diazinon 40 mg/kgBW was administered on day 1-7, while SPI 125, 250, 500, 1,000, 2,000 mg/kgBW were administered on day 8–14 according to the treatment group. Kidney histopathological slides with hematoxylin-eosin (H.E.) staining were assessed using Kocoglu scoring and Kidney damage scores of the treatment groups were analyzed using Pearson test. The maximum effective dose was determined using regression test. The damages found in diazinon-induced rats were tubular degeneration, necrosis, and inflammation with a higher damage score than normal rats (p<0.05). Pearson test showed moderate correlation (coefficient -0.594). Higher SPI doses presented lower kidney damage scores, with 1,359 mg/kgBW being the maximum effective dose. SPI dose and the kidney damage amelioration are moderately correlated with a SPI maximum effective dose to ameliorate kidney damage in diazinon-induced rats of 1,359 mg/kgBW.

Abstract

The aging process leads to skin changes such as wrinkles and loss of elasticity, often accelerated by premature aging caused by factors like UV radiation and reactive oxygen species (ROS). Elastase, an enzyme responsible for degrading elastin in the skin’s extracellular matrix, plays a critical role in this process. This study aimed to investigate the anti-elastase potential of koro komak (Lablab purpureus) extract, a plant rich in polyphenolic compounds, through in vitro testing. A quasi-experimental design was employed, using different concentrations of the extract compared to ascorbic acid as a positive control. Phytochemical screening confirmed the presence of flavonoids, phenols, and tannins. The extract exhibited moderate anti-elastase activity with an IC?? value of 128 ?g/mL, and at 200 ?g/mL concentration, it inhibited elastase enzyme activity by 65.90%. These findings suggest that koro komak extract has promising potential as a natural anti-aging agent by protecting skin elasticity through elastase inhibition.

Abstract

Penggunaan diazinon dalam membasmi hama tanaman akan meninggalkan residu pada tanaman sehingga jika dikonsumsi memberikan dampak buruk. Metabolisme diazinon di hati meningkatkan jumlah radikal bebas dan menurunkan aktivitas enzim antioksidan yang akan mengakibatkan kerusakan sel hati. Kulit bawang merah (Allium cepa L.) mengandung kuersetin yang dapat memperbaiki kerusakan jaringan akibat stres oksidatif. Penelitian ini bertujuan mengetahui hubungan antara dosis infusa kulit bawang merah (IKBM) dan tingkat kerusakan hati tikus yang diinduksi diazinon dan menentukan dosis efektif maksimum IKBM. Tikus dibagi menjadi kelompok normal, diazinon, dan IKBM. Diazinon diberikan dengan dosis 40 mg/kgBB selama 7 hari dilanjutkan dengan IKBM dengan dosis 125, 250, 500, 1.000, dan 2.000 mg/kgBB selama 7 hari. Pengamatan mikroskopik dilakukan terhadap 100 sel hati dengan pewarnaan hematoxylin-eosin (HE) berdasarkan skor Manja Roenigk. Tingkat kerusakan hati antara dua kelompok dianalisis menggunakan uji Mann-Whitney, sedangkan korelasi antara dosis IKBM dan tingkat kerusakan hati, dan dosis efektif maksimum IKBM ditentukan dengan uji regresi. Rerata skor histopatologi hati tertinggi didapatkan pada kelompok diazinon dan terendah pada kelompok normal (p<0,05). Uji regresi menunjukkan terdapat hubungan eksponensial antara dosis IKBM dan tingkat kerusakan hati (p<0,05), yaitu semakin tinggi dosis IKBM, semakin rendah skor histopatologi hati dan dosis efektif maksimum IKBM adalah 1.347,28 mg/kgBB. Sebagai kesimpulan, semakin tinggi dosis IKBM, semakin rendah tingkat kerusakan hati tikus yang diinduksi diazinon. Pemberian IKBM melebihi dosis 1.347,28 mg/kgBB akan meningkatkan kerusakan hati.

Abstract

Introduction: Until now, the impact of Extremely Low Frequency electromagnetic field radiation (ELF-EMF) by extra high voltage transmission lines (500 kV-EHVTL) is still debated. While WHO recommends a threshold of magnetic field exposure of 100 µT for up to 24 hours/day is declared safe for health. This study aims to examine the Integration of Extremely Low Frequency Magnetic Field Studies in Science Education: "Case Study on 500 kV-EHVTL". This study is important to support literacy in Environmental Physics and Environmental Radiation courses. The location of the study is a 500 kV EHVTL building located in Gondang Wetan District, Pasuruan Regency, East Java, Indonesia. Measurement of ELF magnetic field intensity using the EMF Tester-827 tool. The measurement position is at point 0 (directly below), and lateral distances of 50m, 100m, 150m, 200m, and 250m from the EHVTL power grid cable, as well as distances of 0m, 1m, 5m, 10m, and 15m from the EHVTL power grid tower. The intensity of ELF magnetic field exposure just below the EHVTL reached a value of 5.73 µT-10,085 µT (increased 170-234 times) compared to the natural magnetic field. While several research results prove that exposure to magnetic fields with an intensity of around 10 µT in vitro causes an increase in cell proliferation. Increased cell proliferation in the human body can have negative effects on health. Based on the research results it was concluded that an increase in the intensity of ELF magnetic field exposure up to 170-234 times can cause biological effects at the cellular level and has the potential to cause health impacts on humans. it is advisable to avoid living under the EHVTL network, and the WHO recommendation that the threshold exposure value of 100 µT is declared safe for humans exposed for up to 24 hours/day needs to be reviewed

Abstract

Background: Cigarette smoking damages the alveoli through oxidative stress. Shallot peels containing flavonoids, especially quercetin, potentially serve as a daily antioxidant supplement to impede lung tissue damage induced by cigarette smoke. However, the maximum effective dose is yet to be determined. Objective: This research was designed to establish the maximum effective dose of shallot peel infusion (SPI) to prevent oxidative stress and histopathological lung damage induced by cigarette smoke. Methods: This experimental laboratory was a posttest-only control group design. A total of 24 male Rattus norvegicus Wistar strain, were allocated into 6 groups: a control group and 5 SPI-treated groups. All rats were exposed to 2 cigarettes/day and were treated for 28 days with aquabidest and different doses of SPI (0 mg/kgBW, 125 mg/kgBW, 250 mg/kgBW, 500 mg/kgBW, 1,000 mg/kgBW, and 2,000 mg/kgBW). The level of oxidative stress in serum was measured malondialdehyde (MDA) level with ELISA, and histopathological lung damage was estimated using the lung histopathological damage scoring method assessing inflammatory cells, alveolus lumen and inter-alveoli junction.Results: The quadratic regression analysis revealed the maximum effective dose of SPI to prevent oxidative stress and lung damage were 1,435 mg/kgBW and 1,206 mg/kgBW, respectively. In the histopathological examination of the lungs, the administration of SPI up to a dose of 1206 mg/kg BW prevents the inflammatory process caused by cigarette smoke, which is indicated by the number of inflammatory cells, the thickness of the alveolar septum, and the increasingly normal shape of the alveolar lumen.Conclusion: SPI doses of less than 1,206 mg/kgBW are safe and effective daily antioxidant supplements in rats exposed to cigarette smoke and have the potential to be further studied for application in humans.

Abstract

Shallot (Allium cepa L.) contains bioactive compounds with antioxidant effects. In addition to the tuber, the shallot’s peel is a rich source of flavonoids with demonstrated capacity to mitigate oxidative stress. Prior studies have evaluated the antioxidant efficacy of shallot peel in ameliorating organ damage and have established its maximum effective dose. The subsequent step required for its potential therapeutic application is toxicity test. This study aimed to analyze the liver histopathological changes in the acute toxicity test of shallot peel extract (SPE) in rats based on OECD TG 420. This research was an experimental with a post-test-only control group design. Five female rats were used as the control group administered dimethyl sulfoxide (DMSO), while 5 female rats were used in the treatment group administered SPE at 5,000 mg/kg body weight (BW) (one of them had been used for a preliminary test with the same dosage). On day 15, a necropsy was conducted, followed by histopathological observation of the hematoxylin-eosin (HE)-stained liver histopathological slide. The damage to hepatocytes was evaluated using Manja Roenigk criteria. The average histopathological score per liver cell of the control group was 1.226 ± 0.0065 and the treatment group was 1.235±0.0079. The Mann-Whitney test showed that the liver histopathological score of the treatment group was not different from that of the control group (p>0.05). It can be concluded that SPE 5,000 mg/kg does not show acute toxic effects in rats, with LD₅₀ estimated at >5,000 mg/kg according to OECD standards.

Abstract

Shallot skin (Allium cepa L.) is a natural material with potential as a traditional medicine due to its high content of the antioxidant quercetin. However, excessive consumption of shallot skin may cause the antioxidant properties of quercetin to shift to pro-oxidant effects via auto-oxidation and metal-binding reactions. Uncontrolled pro-oxidants induce oxidative stress that damages body cells, including ovarian follicle cells. This acute toxicity study aimed to evaluate the toxic effects of shallot skin extract on the ovary using ovarian follicle count as an indicator. This study employed a true experimental design with a posttest-only control group. The method referred to the OECD 420 guideline (fixed dose procedure) using rats (Rattus norvegicus) as test animals. The results showed no significant difference in the mean follicle counts between the control and treatment groups across all follicle categories: primary follicles (p = 0.278), secondary follicles (p = 0.452), DeGraaf follicles (p = 0.39), corpus luteum (p = 0.752), atretic follicles (p = 1.0), and total follicles (p = 0.60). Thus, follicle counts in all categories did not differ significantly (p>0.05). It can be concluded that shallot skin extract does not exert toxic effects on ovarian follicle numbers in rats.
