Introduction: Individuals with poor oral health have a greater risk factor for systemic diseases. Caries, periodontal disease, and root canal infections are a common dental and oral diseases caused by dominance of Streptococcus mutans, Porphyromonas gingivalis, and Enterococcus faecalis bacteria (S. mutans, P. gingivalis, and E. faecalis). An alternative way to prevent dental and oral diseases is to use herbal medicine as one of the active ingredients for mouthwash or toothpaste. One of the herbs that can be used is Beluntas leaves (Pluchea indica (L.) Less leaves). The objective of study was to analyze the antibacterial activity of ethanol extract of Pluchea indica (L.) Less leaves on the growth of Streptococcus mutans, Porphyromonas gingivalis, and Enterococcus faecalis. Methods: This research was experimental laboratory with post test only control design, using disk diffusion method. There were five concentrations (2.5, 3.5, 4.5, 5.5 and 6.5%, positive controls, and negative controls. Data analysis was performed using One Way Anova and post Hoc test. Results: The ethanol extract of Pluchea indica (L.) Less leaves has moderate-strong antibacterial activity against Streptococcus mutans, Porphyromonas gingivalis, and Enterococcus faecalis. The largest diameter of inhibitory zone in Enterococcus faecalis at a concentration of 6.5% followed by Streptococcus mutans and Porphyromonas gingivalis at the same concentration and the smallest diameter of inhibition zone in Porphyromonas gingivalis, followed by Enterococcus faecalis and Streptococcus mutans at 2.5% concentration. Conclusion: The ethanol extract of Pluchea indica (L.) Less leaves with a concentration of 2.5, 3.5, 4.5, 5.5, and 6.5% has antibacterial activity in inhibiting the growth of Streptococcus mutans, Porphyromonas gingivalis, and Enterococcus faecalis.
Recurrent aphthous stomatitis (SAR) is an oral disease characterized by recurrent ulcers limited to the oral mucosa without other systemic disorders in the patient. SAR can create discomfort and disturbance, especially when performing the functions of mastication, swallowing, and speech. There are predisposing factors that trigger RAS, one of which is stress. This study aimed to determine the relationship between stress levels and the incidence of Recurrent Aphthous Stomatitis (SAR) in undergraduate students at Mulawarman University. This research is a cross-sectional study with a purposive sampling technique. The sample was 380 Mulawarman university students. The data analyses used were univariate and bivariate analyses with a chi square test. The results showed that 82% of students (311 students) were in the moderate category, and 61% (231 students) did not experience RAS. The chi-square test showed no significant relationship between mild and moderate stress levels and moderate and severe stress on SAR. There was a significant relationship between mild and severe stress levels on SAR, where students with mild stress levels tended not to experience SAR 1.731 times compared to students with severe stress. There was a relationship between stress levels and recurrent aphthous stomatitis in Mulawarman University students.
Peningkatan permeabilitas sel eritrosit yang terinfeksi Plasmodium falciparum terhadap ion dan makromolekul diketahui sebagai mekanisme parasit untuk memenuhi nutrisi dalam proses pertumbuhan. Peningkatan permeabilitas terhadap kalsium masih merupakan hal yang kontradiktif dalam peranannya meningkatkan pertumbuhan Plasmodium falciparum dalam sel eritrosit. Tujuan dari penelitian ini adalah mengetahui peningkatan pertumbuhan Plasmodium falciparum dalam sel eritrosit pasca pemberian kalsium. Biakan primer Plasmodium falciparum dalam medium biakan RPMI 1640 yang menghasilkan parasitemia 15%, dilakukan inokulasi untuk pembuatan subkultur yang menghasilkan parasitemia 2% dan dilakukan pembagian untuk kelompok perlakuan pemberian kalsium dan kontrol (ML 10%) dengan replikasi 3 kali. Pengamatan dilakukan hari pertama sampai hari ke-6 setelah perlakuan. Pengamatan pertumbuhan dilakukan dengan parameter parasitemia, bentuk skizon, hemolisis dan kalsium intraseluler. Hasil penelitian menunjukkan bahwa pemberian kalsium menghasilkan peningkatan tertinggi jumlah total rerata parasitemia (11,09 ± 4,01) (Rerata ± SD), bentuk skizon (23,52 ± 10,83), hemolisis (0,278 ± 0,03) dan kalsium intraseluler (6,55 ± 1,88), dibandingkan dengan media biakan kontrol (ML 10%). Analisis T-test (α= 0,05) menghasilkan perbedaan yang signifikan pada parameter parasitemia, bentuk skizon, hemolisis tetapi tidak memberikan perberbedaan yang signifikan pada parameter kalsium intraseluler.
Tahongai (Kleinhovia hospita Linn) merupakan tanaman herbal yang banyak dijadikan obat tradisional oleh masyarakat suku Dayak. Tahongai memiliki berbagai khasiat yang dapat digunakan untuk menunjang kesehatan tubuh. Didalam tanaman ini juga terdapat senyawa aktif yang dapat berfungsi sebagai zat antibakteri. Terutama pada bagian daun Tahongai, memiliki kandungan senyawa aktif seperti flavonoid, alkaloid, saponin, dan terpenoid yang dapat berfungsi sebagai senyawa antibakteri. Penelitian ini bertujuan untuk mengetahui efek antibakteri dari ekstrak daun tanaman Tahongai terhadap pertumbuhan bakteri Actinobacillus actinomycetemcomitans secara In-vitro. Desain penelitian ini adalah post test only control group design dengan menggunakan uji Disc Diffusion (Kirby-Bauer). Penelitian ini menggunakan bakteri A. actinomycetemcomitans yang diberi perlakuan ekstrak etanol daun Tahongai (K. hospita Linn) dengan konsentrasi 5%, 10%, 15%, dan 20%. Kemudian dilakukan pengulangan sebanyak lima kali. Hasil penelitian menunjukkan bahwa ekstrak etanol daun Tahongai (K. hospita Linn) tidak mampu menghambat pertumbuhan bakteri A. actinomycetemcomitans pada konsentrasi 5%, 10%, 15%, dan 20%.
