Objective: The plant mahkota dewa (Phaleria macrocarpa) is known to have anti-inflammatory effects. This study aimed to determine whetherchitosan nanoparticles containing mahkota dewa leaf extract would yield superior anti-inflammatory effects in the colon of a mouse model of dextransodium sulfate (DSS)-induced ulcerative colitis, compared with ethanol extract alone after testing the acute toxicities (lethal dose) of both preparations.Methods: For acute toxicity testing, 10 Sprague-Dawley rats were administered 6000 mg/kg body weight (BW) of leaf extract alone or with nanoparticles.Subsequently, mice were divided into the following six groups to determine the anti-inflammatory effects: Untreated, negative control (DSS 2% w/v), leafextract at 12.5 or 25 mg/kg BW, and leaf extract in chitosan nanoparticles at 6.25 or 12.5 mg/kg BW. To induce colitis, DSS (2% w/v) was administeredthrough drinking water for 6 weeks. The anti-inflammatory effect was observed histopathologically by imaging the inflammatory cells of the mice colonwith hematoxylin-eosin (HE) staining.Results: For acute toxicity testing, 10 Sprague-Dawley rats were administered 6000 mg/kg BW of leaf extract alone or with nanoparticles. Subsequently,mice were divided into the following six groups to determine the anti-inflammatory effects: Untreated, negative control (DSS 2% w/v), leaf extract at12.5 or 25 mg/kg BW, and leaf extract in chitosan nanoparticles at 6.25 or 12.5 mg/kg BW. To induce colitis, DSS (1% w/v) was administered throughdrinking water for 6 weeks. The anti-inflammatory effect was observed histopathologically by imaging the inflammatory cells of the mice colon withHE staining.Conclusion: Chitosan nanoparticles containing mahkota dewa leaf extract can be included in the practically non-toxic class of materials. However, anethanol extract of mahkota dewa leaf effectively inhibited DSS-induced inflammation in the mouse colon, regardless of delivery vehicle.
Objective: The incidence of small intestine cancer (SIC) is rising despite available preventive measures. Kaempferol and quercetin are a potential chemopreventive agent for SIC, but in vivo findings are inconclusive. We aim to study the effects of kaempferol and quercetin on colitis-associated small intestine carcinogenesis in mice.Methods: Suppression effect was tested using mice divided into 6 groups of treatment, i.e.; normal (N) group, negative control (NC), leaf extract (medium dose [MD]) dose 12.5 and 25 mg/kg body weight (BW), leaf extract chitosan and nanoparticle of mahkota dewa (NPMD) dose 6.25 and 12.5 mg/kg BW. Dextran sulfate sodium induction of 1% w/v was administered through drinking water for 6 weeks of treatment. The suppression effect was observed histopathologically by counting the mitotic cells and hyperplasia cells of the crypt of small intestine with hematoxylin-eosin staining.Results: Mitosis cells mean of NC group was not significant difference either with MD 12.5 (p=0.394) or MD 6.5 (p=0.310). However, mitosis cell mean appears to be lower in the NPMD 12.5 (p=0.09) and NPMD 6.25 (p=0.05) groups than the NC group. There was a significant difference among the mean of hyperplasia NC group and MD and also NPMD group. Significant difference also can be showed between MD 12.5 and MD 25 (p=0.026), and between NPMD 6.25 and NPMD 12.5 (p=0.002), and between MD 12.5 and NPMD 12.5 (p=0.002).Conclusion: Our results demonstrate suppression of hyperplasia small intestine by either nanoparticle or extract of Phaleria macrocarpa extracts. The suppression of mitosis was showed by administration of nanoparticle.
Acute diarrhea is liquid stool with a frequency of more than 3 times a day and lasts less than 14 days. One of the most common causes of acute diarrhea is Escherichia coli. Diarrhea caused by bacteria can be treated with the use of antibiotics, but the relatively high intensity of antibiotic use causes various health problems, especially bacterial resistance. Therefore, the search for antibacterial agents derived from natural ingredients was carried out as an alternative treatment. Bay leaf (Syzygium polyanthum) is one of the natural ingredients that has the potential as an antibacterial because it contains active compounds such as essential oils, flavonoids (quercetin), saponins, tannins, and alkaloids. This study aimed to analyze the antibacterial activity of the ethanolic extract of bay leaves on the growth of Escherichia coli. This research uses the dilution method which aims to determine the Minimum inhibitory concentration (MIC) and Minimum bactericidal concentration (MBC). The results showed that the MIC value at a concentration of 200mg/ml and the MBC value at a concentration of 500mg/ml.
Usaha Mikro Kecil Menengah (UMKM) memiliki peranan penting dalam perekonomian negara, baik dari sisi penciptaan lapangan kerja maupun dari sisi jumlah usaha. UMKM Cendawan House memiliki kendala dalam aktivitas usahanya berupa belum dimilikinya pembukuan yang baik, struktur, dan pembagian tugas sehingga berdampak pada tingkat produktivitas dan pemasaran produk yang dihasilkan. Berdasarkan latar belakang tersebut maka dilaksanakan kegiatan pengabdian dengan mitra pengabdian yakni UMKM Cendawan House yang berada di Kelurahan Tebing Tinggi Okura, Kecamatan Rumbai Pesisir, Kota Pekanbaru, Provinsi Riau. Kegiatan pengabdian yang dilakukan yakni pemberdayaan melalui sosialisasi manajemen usaha untuk mengatasi masalah manajemen UMKM Cendawan House. Hasil dari kegiatan ini adalah mitra memiliki pembukuan yang baik, struktur, dan pembagian tugas serta wewenang yang jelas yang kemudian juga berdampak positif terhadap peningkatan produksi dan pemesaran produk yang dihasilkan. Dari kegiatan ini disimpulkan bahwa permasalahan yang dihadapi mitra dapat diselesaikan setelah pelaksanaan kegiatan ini.
The needs of guidance and counseling services in elementary schools appears from characteristics and problems developments that occur during age child elementary school. Characteristics and optimization student development in elementary school need a better service assistance. The needs of student development teach what you need fulfilled for smoothness development task that they live, and increase student problems development that more complex. On maintenance education in elementary schools, school counselors play a role help achievement development personal, social, academic, and career participant educate. In order to achieve that goals, ideally every elementary school have a school counselor. Maintenance service guidance and counseling should be done by power professionals who have qualification academic and competence academic and competence professional in accordance mandate legislation.
