Abstract

Penyakit diabetes melitus merupakan salah satu penyakit degeneratif yang hingga kini masih belum tuntas terapinya dan masih menjadi ancaman serius bagi dunia kesehatan di Indonesia dan dunia. Tujuan penelitian ini adalah mengetahui kadar insulin dan C-peptide tikus putih penderita diabetes melitus tipe I yang diberikan transplantasi allograf pancreatic stem cell dengan laparotomi intrapankreatik. Penelitian ini dilakukan selama 6 bulan (Juli?Desember 2014) di lab. Stem Cell, Institute of Tropical Diseases, Universitas Airlangga, Surabaya. Dua belas tikus putih jantan Rattus novergicus galur Wistar dibagi secara acak menjadi dua kelompok . Kelompok pertama (P0) disuntik aloksan 150 mg/kg bobot badan tanpa terapi stem cell . Kelompok kedua disuntik aloksan dengan dosis 150 mg/kg bobot badan dan diterapi dengan 1x106/kg bobot badan stem cell pankreas secara laparotomi intrapankreatik (P1). Akhir penelitian adalah pada hari ke-31 percobaan. Hasil penelitian menunjukkan bahwa kadar glukosa darah pada akhir penelitian berbeda sangat nyata (p <0,01) antara kelompok perlakuan yang menerima terapi stem cell (P1) dengan P0 kontrol positif, meskipun nilai kadar glukosa darah rata-rata tidak senormal seperti pada hari ke-1. Tingkat C-peptide dan insulin P0 dan P1 berbeda sangat nyata (p<0,01). Dapat disimpulkan bahwa terapi stem cell secara laparotomi intrapankreatik dapat menurunkan kadar glukosa darah, serta meningkatkan kadar C-peptide dan insulin.

The aim of this study was to describe the level of insulin and C-peptide in diabetes mellitus type I white rats treated with  pancreatic stem cell allograft through intrapancreatic laparotomy. This study was conducted at the Institute of Tropical Diseases, Universitas Airlangga, Surabaya in a 6 month period (July?December 2014). Twelve male white rats Rattus novergicus Wistar strain, were randomly divided into two groups. The first group (P0) was injected by alloxan, 150 mg/kg body weight, without stem cell therapy. Another group was injected by alloxan, 150 mg/kg body weight, and was treated with 1x106/kg body weight pancreatic stem cell throughintrapancreatic laparotomy (P1). The experiment was finalized on the 31th day of the experiment. The results showed that the blood glucose levels at the end of experiment were highly significantly different p<0.01 between the treatment group that received stem cell therapy (P1) and P0 positive control, although the average value of blood glucose levels was not as normal as on the first day. C-peptide and insulin levels of P0 and P1 group differed significantly (p<0.01). It can be concluded that stem cell therapy through intrapancreatic laparotomy can reduce blood glucose levels and increase the levels of C-peptide and insulin.

Abstract

Plasmodium  resisten terhadap artemisinin menjadi salah satu permasalahan kesehatan di dunia karena belum ada obat baru pengganti artemisinin. Resistensi P. falciparum terhadap obat antimalaria  artemisinin dapat terjadi karena dipengaruhi oleh faktor internal dari P. falciparum, antara lain induksi ekspresi gen yang mengekspresikan protein. Salah satu gen tersebut adalah gen Triptophan-rich Protein (PArt). Fungsi Triptophan-rich Protein penting dalam membrane-spanning protein dan berperan dalam folding protein untuk menjaga kontak hidrofobik. Penelitian ini bertujuan membuktikan overekspresi gen Triptophan-rich Protein P. falciparum galur Papua 2300 yang disebabkan oleh paparan artemisinin berulang in vitro. Waktu penelitian dilaksanakan bulan Februari sampai November 2013. Tempat penelitian di Rumah Sakit Penyakit Tropik dan Infeksi Universitas Airlangga. Desain penelitian yang digunakan adalah experimental design dengan post test only control group design. Kultur  in vitro P. falciparum galur Papua 2300 dibagi dalam kelompok kontrol (K) dan kelompok perlakuan paparan artemisinin berulang, yaitu paparan artemisinin ke-1 (PO1), paparan artemisinin ke-2 (PO2) dan paparan artemisinin ke-3 (PO3) menggunakan konsentrasi IC50. Ekspresi gen Triptophan-rich Protein (PArt) diukur dengan qRTPCR. Hasil menunjukkan paparan artemisinin berulang pada P. falciparum  dapat meningkatkan level ekspresi gen Part (2??CT) relatif terhadap kontrol. Simpulan, paparan artemisinin in vitro menyebabkan overekspresi gen  Tryptophan-rich Proteins(PArt) oleh promoter P. falciparum galur Papua 2300.

Even though the mechanism of artemisinin resistance has not been clearly understood, the resistance of P. falciparum towards the antimalaria artemisinin may occur due to the influence of by the internal factors of P. falciparum, including the induction of the protein-expressing gene expression. One of the genes is the Triptophan-rich Protein (PArt) gene that is important in the membrane-spanning protein and plays a role in protein folding to maintain hydrophobic contact.. This study aimed to prove that  Triptophan-rich Protein overexspression in P. falciparum Papua 2300 strain may cause repeated artemisin exposure in vitro. This study was performed in a period from February to November 2013 in Infection and Tropical Diseases Hospital, Airlangga University. The design used was experimental study with post-test only control group design. In-vitro culture of P. falciparum Papua 2300  strain were divided into a control group (K) and treatment groups that were treated regularly with artemisinin, i.e. artemisinin exposure I (PO1), artemisinin exposure 2 (PO2) and artemisinin exposure 3 (PO3)  using IC50 concentration. The Tryptophan-rich Protein gene expression level was detected using  qRTPCR. The result showed that in vitro repeated artemisinin exposure in P.  falciparum  Papua 2300 strain  relatively increased the expression level of the Tryptophan-rich Protein (PArt) genes (2??CT)  when comparedwith control. In conclusion, in vitro artemisinin exposure may cause Tryptophan-rich Proteins (PArt) gene overexpression by P. falciparum  Papua 2300 strain promoter. [MKB. 2015;47(3):129?36]Key words: Artemisinin, phenotype, Triptophan-rich Protein (PArt) gene,  P. falciparum Papua 2300 DOI: 10.15395/mkb.v47n3.593
