Luka fisik yang dialami oleh penderita hiperglikemia dapat berkembang menjadi ulkus diabetikum. Sel fibroblas merupakan sel yang bertanggung jawab dalam mengembalikan struktur dan fungsi pada jaringan ulkus. Bruguiera gymnorrhiza diketahui memiliki kemampuan sebagai antioksidan dan antiinflamasi, sehingga berpotensi membantu pemulihan sel β pankreas serta penyembuhan ulkus. Penelitian ini bertujuan untuk mengetahui pengaruh ekstrak daun B. gymnorrhiza terhadap pemulihan sel β pankreas dan penyembuhan ulkus pada mencit diabetes. Percobaan dilakukan pada 24 ekor mencit dibagi menjadi enam kelompok dengan empat pengulangan, meliputi kontrol normal (KN), kontrol negatif (K-), dosis I (42 mg/kg BB), dosis II (84 mg/kg BB), dosis III (126 mg/kg BB), dan kontrol positif (KP). Mencit pada kelompok selain KN diinduksi aloksan sebanyak 2,5 mg/kg BB. Analisis skoring kerusakan sel β pankreas dan jumlah sel fibroblas pada ulkus dilakukan menggunakan uji statistic Kruskal-Wallis. Hasil penelitian menunjukkan bahwa pemberian ekstrak daun B. gymnorrhiza secara signifikan mempengaruhi pemulihan sel β pankreas (p&lt;0,05) dan meningkatkan jumlah sel fibroblas pada jaringan ulkus (p&lt;0,05), dengan efek paling optimal terlihat pada dosis II (84 mg/kg BB) dan dosis III (126 mg/kg BB). Dosis optimal ini menghasilkan pemulihan yang signifikan baik dalam pemulihan pankreas maupun dalam peningkatan jumlah fibroblas, yang berperan penting dalam penyembuhan ulkus. Dengan demikian, ekstrak daun B. gymnorrhiza memiliki potensi sebagai bahan obat herbal yang efektif untuk pemulihan pankreas dan penyembuhan ulkus diabetikum.</em></p> 2024-10-21T00:00:00+00:00 Copyright (c) 2024 Erlix Purnama, Jannatul Makwa , Yusril Virda Muttaqien https://e-journal.upr.ac.id/index.php/borneo/article/view/16682 Etnobotani dan Pengelolaan Tumbuhan Sarang Semut (Myrmecodia sp.) oleh Suku Dayak Ngaju di Desa Rangan Surai, Kabupaten Katingan 2024-10-27T13:33:23+00:00 Sri Wahyunia sw18@gmail.com Siti Sunariyati sunariyati1516@mipa.upr.ac.id Widya Krestina widyakrestina@yahoo.com <p><em>Keanekaragaman jenis tumbuhan di wilayah Kalimantan Tengah merupakan sumber daya alam hayati yang perlu dipertahankan salah satu diantaranya adalah tumbuhan sarang semut (Myrmecodia sp.) karena tumbuhan tersebut memiliki potensi sebagai obat.

The statistical population consisted of 500 rice farmers from three mainly rice-growing villages of Langrod county, Gilan province, and the sample size was 211. To select this sample size, simple random sampling was used. The data was collected through a questionnaire. Its face validity was based on a survey of expert opinions. To determine the reliability of the measurement tool, face-to-face interviews were conducted with a sample of 30 people outside of the main sample, and the calculated Cronbach's alpha coefficients confirmed the research tool. Descriptive statistics, correlation tests, and factor analysis were used in SPSS 22 software to analyze the data. Deviation distance from the mean method was used to group the attitudes of rice farmers. The results showed that 18% of the respondents have a negative attitude towards organic agriculture, about 70% have a somewhat positive attitude, and about 12% have a completely positive attitude, and the attitude of the surveyed farmers is influenced by the factors of caring for nature and preserving the soil fertility, the quality and quantity of agricultural products, the value and importance of rural landscapes, traditionalism, the desire to preserve past customs and traditions, and the impact of personal experiences which account for 19.60, 11.44, 9.25, 9.06 and 8.98 percent of the explained variance, respectively.</em></p> 2024-11-16T00:00:00+00:00 Copyright (c) 2024 Fatemeh Askari Bozayeh, Shahab Nobakht Haghighi, Hanif Amrulloh, Hamed Kioumarsi, Seyed Mohammadreza Mahdavian
