Abstract

Cigarette residue toxins can accumulate in the body, including the pancreas, which potentially reduces pancreas function. In addition, the active compounds in cigarettes are reporting to interfere with an elevation of reactive oxygen species, leading to disruption of pancreatic microstructures. Furthermore, pancreatic cell dysfunction is responsible for developing diabetes mellitus disease. The objective of this study was to analyze the effect of thirdhand smoke exposure on mice pancreatic microstructure image. It was an in vivo laboratory experimental study with a completely randomized design at the Medical Biology Laboratory of the Universitas Islam Bandung from November 2020–June 2021. The subjects were 20 adult male mice aged 8–10 weeks, weighing 25–30 grams, in good health condition, and randomly divided into two groups (control group and treatment group exposed to thirdhand cigarette smoke for four weeks). After the completion of the exposure period, pancreatic cells isolation was performing. The parameters observed in this study were the number and diameter islet of Langerhans. Data analysis used the independent t test parametric (α=5%). The results showed that the number and diameter islet of Langerhans in the treated group were significantly lower than the control group (p<0.05). The average number in the control group was 9.40±3.20, while in the treatment group was 4.90±2.74 (28% smaller). The average diameter of control was 225.96±50.15 mm, while treatment was 162±49.68 mm (50% lower). In conclusion, thirdhand smoke exposure alters the pancreas microstructure. The toxic compounds on thirdhand cigarette smoke are involving in generating an elevation of free radical levels, depletion of antioxidants, and alteration of signal transduction resulted in acceleration of apoptosis rate of the islet of Langerhans, especially pancreatic β-cells. PENGARUH PAPARAN ASAP ROKOK TERSIER PADA GAMBARAN MIKROSTRUKTUR PANKREAS MENCITToksik residu rokok dapat terakumulasi pada tubuh, termasuk pankeas sehingga dapat menurunkan fungsi pankreas. Selain itu, senyawa aktif dalam rokok dilaporkan meningkatkan radikal bebas yang menyebabkan kerusakan mikrostruktur pankreas. Selanjutnya, disfungsi sel pankreas meningkatkan risiko diabetes melitus. Penelitian ini bertujuan menganalisis pengaruh asap rokok tersier terhadap gambaran mikrostruktur pankreas mencit. Penelitian ini merupakan penelitian eksperimental laboratorium in vivo dengan rancangan acak lengkap di Laboratorium Biologi Medik Universitas Islam Bandung periode November 2020–Juni 2021. Subjek penelitian adalah 20 mencit jantan dewasa berumur 8–10 minggu, bobot 25–30 gram, kondisi sehat, dan dibagi secara acak menjadi dua kelompok (kelompok kontrol dan kelompok perlakuan yang mendapat paparan asap rokok tersier selama empat minggu). Setelah periode pemberian paparan selesai, dilakukan isolasi sel pankreas. Parameter yang diamati dalam penelitian ini adalah jumlah dan diameter pulau Langerhans (islet of Langerhans). Analisis data menggunakan parametrik independent t test (α=5%). Hasil penelitian menunjukkan bahwa jumlah dan diameter pulau Langerhans pada kelompok perlakuan lebih rendah dibanding dengan kelompok kontrol (p<0,05). Jumlah rerata pada kelompok kontrol adalah 9,40±3,20, sedangkan pada kelompok perlakuan 4,90±2,74 (lebih rendah 28%). Diameter rerata pada kelompok kontrol adalah 225,96±50,19 mm dan kelompok perlakuan 162,89±49.68 mm (lebih rendah 50%). Simpulan, paparan asap rokok tersier dapat memengaruhi gambaran mikrostruktur pankreas. Senyawa toksik pada asap rokok tersier diduga terlibat dalam peningkatan kadar radikal bebas, penurunan kadar antioksidan, dan perubahan transduksi sinyal yang mengakibatkan peningkatan laju apoptosis pulau Langerhans, terutama sel β pankreas.

Abstract

Massive and long term insecticide use causes resistance of mosquitos to insecticides. This research has a goal for assessing the resistance of Aedes aegypti to the insecticides of permethrin 0.25%, malathion 0.8%, and transfluthrin 25% in the Universitas Islam Bandung Tamansari campus. The Aedes aegypti resistance in the Universitas Islam Bandung Tamansari campus Bandung city to insecticides measured with the susceptibility test in September 2015. The susceptibility test to the permethrin 0.25% and malathion 0.8% insecticides implemented by using WHO standard instruments and methods. The susceptibility test to transfluthrin 25% implemented by using commercial insecticide according to the usage suggestion. The total mosquitos that died after the exposure of permethrin 0.25%, transfluthrin 25%, and malathion 0.8% for 60 minutes were 20%, 23%, and 80%. The WHO criteria state that mosquitos were still susceptible to insecticides if the death rate is 98–100%, tolerant if the death rate is 80–97%, and mosquitos are resistant if the death rate is less than 80%. In conclusion, the Aedes aegypti mosquitos in the Universitas Islam Bandung Tamansari campus are already resistant to the insecticides permethrin 0.25% and transfluthrin 25% and tolerant to malathion 0.8%. RESISTENSI AEDES AEGYPTI TERHADAP INSEKTISIDA PERMETHRIN 0,25%, MALATHION 0,8%, DAN TRANSFLUTHRIN 25% DI KAMPUS UNIVERSITAS ISLAM BANDUNG TAMANSARIPenggunaan insektisida secara masif dan jangka panjang menimbulkan resistensi nyamuk terhadap insektisida.

Abstract

The pseudoephedrine in pregnant women associated with an increased risk of hypertension and increased heart rate. These conditions force the heart to work harder and cause changes in heart structure, such as left ventricular hypertrophy due to an increase in the number and size of muscle cells. This study aims to determine pseudoephedrine administration in early pregnancy on mice hearts histological features. This study was pure in vivo with a completely randomized design conducted at Medical Biology Laboratory, Faculty of Medicine, Universitas Islam Bandung, from January to August 2017. Subjects were 18 pregnant adult female mice randomly divided into four groups. One control group and three test groups were given oral pseudoephedrine every day at 0.312 mg/24 hours (P1); 0.624 mg/24 hours (P2); and 1.248 mg/24 hours (P3) for seven days starting from the age of pregnancy on day 1. On the 18th day of gestational age, mice sacrificed, then the heart organ was processed into microscopic preparations and stained by Harris’ hematoxylin-eosin (HE) staining. Microscopic observations made using a microscope equipped with an optilab viewer with raster image 3. The results showed that the P3 group had a thicker left ventricular wall and significantly more heart muscle nuclei per mm3 than the control group (p<0.05). The results show that the administration of high doses of pseudoephedrine in early pregnancy can affect the structure of the heart. PENGARUH PEMBERIAN PSEUDOEFEDRIN PADA MASA AWAL KEBUNTINGAN TERHADAP GAMBARAN HISTOLOGI JANTUNG MENCIT BETINAAktivitas vasokontriksi pseudoefedrin pada ibu hamil diduga kuat berkaitan dengan peningkatan risiko hipertensi dan denyut jantung. Kondisi tersebut memaksa jantung bekerja lebih berat dan dapat menyebabkan perubahan struktur jantung seperti hipertrofi ventrikel kiri akibat peningkatan jumlah dan ukuran sel-sel otot. Tujuan penelitian ini mengetahui pengaruh pemberian pseudoefedrin pada masa awal kebuntingan terhadap gambaran histologi jantung mencit betina. Penelitian ini merupakan eksperimental laboratorium murni in vivo menggunakan rancangan acak lengkap yang dilaksanakan di Laboratorium Biologi Medik, Fakultas Kedokteran, Universitas Islam Bandung dari bulan Januari hingga Agustus 2017. Subjek penelitian adalah 18 mencit betina dewasa bunting yang dibagi secara acak menjadi empat kelompok. Satu kelompok kontrol dan tiga kelompok uji yang diberi pseudoefedrin oral setiap hari dengan dosis 0,312 mg/24 jam (P1); 0,624 mg/24 jam (P2); dan 1,248 mg/24 jam (P3) selama 7 hari dimulai dari umur kebuntingan hari ke-1. Pada hari ke-18 umur kebuntingan, mencit dikorbankan kemudian organ jantung diproses menjadi sediaan mikroskopis dan dilakukan pewarnaan Harris’ hematoxylin-eosin (HE). Pengamatan sediaan mikroskopik dilakukan dengan menggunakan mikroskop yang dilengkapi dengan optilab viewer dengan image raster 3. Hasil penelitian menunjukkan kelompok P3 memiliki dinding ventrikel kiri yang lebih tebal dan jumlah nuklei otot jantung yang lebih banyak per mm3 secara signifikan dibanding dengan kelompok kontrol (p<0,05). Hasil menunjukkan bahwa pemberian pseudoefedrin dosis tinggi pada masa awal kehamilan dapat memengaruhi struktur jantung.

Abstract. Liver cancer is the second leading cause of cancer death globally in 2020. One of the treatment options for liver cancer is chemotherapy. Chemotherapy for liver cancer still has many side effects and high incidence of resistance. One of the efforts to overcome this problem is the development of phytopharmaceuticals. Soursop leaf extract (Annona muricata L.) has been studied and showed various anticancer effects such as cytotoxicity, induction of apoptosis, necrosis, and inhibition of proliferation. Herbal extracts are being developed in nanoparticle preparations because they can increase bioavailability. The purpose of this study was to examine the anticancer effect of alginate nanoparticles (NP) ethanol extract of soursop leaf (Annona muricata L.) on HepG2 liver cancer cell cultures. This study is an experimental study in vitro on HepG2 liver cancer cell cultures. Cytotoxicity test was carried out using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-2H-tetrazolium bromide (MTT) assay. The IC50 value was obtained by probit regression analysis using software SPSS. The results showed that the IC50 NP alginate of soursop leaf ethanol extract was 14.5 g/mL. In conclusion, NP alginate ethanolic extract of soursop leaves has a high anticancer effect on HepG2 liver cancer cell cultures. The anticancer effect can be caused by the content of annonaceous acetogenin (AGE) and flavonoids. Abstrak.
