Abstract

Abstrak. Meluasnya penyebaran resistensi Plasmodium terhadap antimalaria merupakan permasalahan utama dalam pemberantasan malaria.Upaya cepat untuk mengatasi masalah tersebut, salah satunya melalui penemuan dan pengembangan antimalaria barudari tumbuhan obat yang secara empiris telah terbukti khasiatnya. Eurikumanon dari akar tumbuhan Eurycoma longifolia, Jack telah terbukti memiliki aktivitas antimalaria. Permasalahan dalam pengembangan eurikumanon dari bahan alam adalah biaya isolasi yang mahal, sehingga perlu usaha kreatif dan inovatif untuk mendapatkan turunannya. Semisintesis turunan eurikumanon merupakan langkah awal pengembangan eurikumanon menuju total sintesis guna memenuhi kebutuhan global. Penelitian ini menggunakan eurikumanon dari akar pasak bumi untuk semisintesis turunannya dengan menggunakan farmakofor tionil klorida, asetil klorida, asam klor asetat, asam triklor asetat dan asam trifluoro asetat. Struktur eurikumanon dan turunan hasil semisintesisditentukan secara analisis spektroskopi. Hasil ekstraksi serbuk akar pasak bumi, diperoleh ± 50 g (5%) ekstrak kental. Fraksinasi terhadap ekstrak tersebut secara kromatografi cair vakum (KCV) diperoleh fraksi terkonsentrasi eurikumanon 20 g (2%). Isolasi eurikumanon dari fraksi ini diperoleh eurikumanon 0,03%. Hasil semisintesis turunan eurikumanon diperoleh eurikumanon diklorida 60,10%, eurikumanon monoasetat55,25% , eurikumanon monoklor asetat 55,25%., eurikumanon monotriklor asetat 53,25% dan eurikumanon monotrifluoro asetat 75,65%.Kata kunci: eurikumanon, semisintesis dan turunan eurikumanon Abstract.The  widespread of resistant Plasmodium to antimalarial is  a mainly  problem in treatment of malaria. The fast effort to overcome the problem is the discovery and development of  new antimalarial from medicinal plant which is empirically proven. Eurycomanone from pasakbumi roots (Eurycoma longifolia, Jack) has been proven  as  antimalaria. The problem in development  of eurycomanone  is the high cost of isolation, therefore needed  the creative and inovative effort for getting its derivatives  by  semisynthesis and total synthesis to fill the need of new antimalarial  drugs globally. This research used isolated eurycomanone for semisynthesize its derivatives by using pharmacophore thionyl chloride, acetyl chloride, chloracetic acid, trichlor acetic acid and trifluoro acetic acid. The chemical stucture of them were determined by spectroscopic analysis. The result of extraction of pasak bumi roots is obtained  ± 50 g (5%) thick extract. The fractination of this extract by vacum liquid chromatography (VLC) is obtained eurycomanone  fraction ± 20 g (2%). Isolation of eurycomanone from this fraction is yielded  eurycomanone ± 0,03%. Semisynthesis of eurycomanone derivatives  were obtained eurycomanone dichloride  60,10%, eurycomanone monoacetic 55,25% , eurycmanone monochlor acetic 55,25%., eurycomanone monotrichlor acetic 53,25% and eurycomanonone monotrifluoro acetic 75,65%.Keywords: eurycomanone, semisynthesis and eurycomanone derivatives

Abstract

Antimicrobial peptides naturally play a role in the innate  immune system of any living organisms. These small  molecules are known as "ancient weapon" and also  recognized as natural antibiotics. Antimicrobial  peptides  have  distinct  characteristics  including  their  unique  structures  which  are strongly  correlated  to  their  antimicrobial  activities.  Recently  the  development  of  antimicrobial peptides as future antimicrobial agents has become a major issue in the pharmaceutical business. This  article  will  discuss  the  natural  role  of  antimicrobial  peptides  in  host  defence  system  and  the relationship of their structure with antimicrobial activity. This article will also discuss the challenge in developing antimicrobial peptides as future antimicrobial agents.

Abstract

Wound healing is a physiological response of the body to restore continuity, structure and function ofthe injured tissue. Onion is one of the plants that are empirically used by the community to heal wounds.The purpose of this study was to observe the effect of topical extract of onions (Allium cepa) on woundhealing process in mice (Mus musculus) strain BalbC. This study used the posttest-only control groupdesign with completely randomized design (CRD). The samples were 12 male mice with weight ranged of22-32 g divided into four treatments; i.e.: Vaseline, topical extract of onion 5%, topical extract of onion30% and topical extract of onion 55% with 3 replications. Wound healing evaluated macroscopically toobserve hyperemia, wound contraction, granulation, crusting and pus production; and microscopically bycounting the number of fibroblasts on day 10. Hyperemia, granulation, crusting and pus production wereanalyzed descriptively. Wound contraction and the number of fibroblasts were analyzed using ANOVA(p<0.05) and followed with Duncan’s test (p<0,05). Descriptive observations obtained hyperemia lasteduntil day 3, granulation in wounds used topical extract of onion 30% and 55% were faster than the other,crusting lasted until day 6 and the production of pus was not found in any treatment. Statistical testresults showed that topical extract of onion 55% significantly affected wound contraction and topicalextract of onion 30% and 55% significantly affected maturation, which characterized by the decreasednumber of fibroblasts. The results of this study showed that topical extract of onion had significant effect(p<0.05) on wound healing and the effect was in line with the increased concentration of the onion extract.

Abstract

Latar belakang. Malnutrisi merupakan keadaan tubuh yang tidak mendapatkan asupan gizi yang cukup. Salah satu penyakit infeksi yang dapat menyebabkan malnutrisi adalah diare. Kejadian diare di Puskesmas Batoh merupakan angka tertinggi dari seluruh puskesmas yang ada di Kota Banda Aceh.Tujuan. Mengetahui pengaruh diare terhadap malnutrisi dan Risiko Relatif (RR) diare pada Balita malnutrisi di Puskemas Batoh Kota Banda Aceh.Metode. Pengambilan data dilakukan menggunakan data primer dari Wawancara serta pengukuran status gizi dan data sekunder dari rekam medik dan Kartu Menuju Sehat (KMS).Hasil. Jumlah subjek 42 Balita yang dibagi dalam 2 kategori, yaitu diare sering dan jarang. Karakteristik subjek digambarkan secara deskriptif. Data dianalisis dengan uji Chi-square. Total 42 Balita, 52,4% adalah gizi kurang dan dengan uji Chi-square menunjukkan bahwa variabel independen (diare) berpengaruh terhadap malnutrisi (p<0,05). Risiko relatif (RR) menunjukkan bahwa Balita dengan diare sering berisiko menjadi malnutrisi sebesar 10,00 kali.Kesimpulan. Diare memiliki hubungan yang signifikan terhadap kejadian malnutrisi. Balita dengan diare sering memiliki risiko 10,00 kali untuk menjadi malnutrisi.Â
