Abstract

ABSTRAK Latar belakang Limfoma malignum merupakan suatu keganasan dari sel-sel jaringan limfoid. Limfoma non-Hodgkin (LNH) tipe sel B mencakup 90% dari seluruh limfoma di seluruh dunia, dengan angka kejadian mencapai 4% kasus baru per tahun. Regimen kemoterapi CHOP (Cyclophospamide, Hydroxydaunorubicin, Oncovin, Prednison) merupakan standar terapi penderita LNH, dengan angka respon komplit hanya sebesar 40% sampai 50%. Pada sekitar 30% kasus LNH tidak berespon dengan kemoterapi CHOP dan terjadi progresi penyakit bahkan sampai terjadi kematian. Respon kemoterapi yang efektif ditandai dengan peningkatan jumlah sel yang mengalami apoptosis. Protein bcl-2 berfungsi sebagai anti-apoptosis, sedangkan caspase-3 berperan sebagai eksekutor caspase (pro-apoptosis). Penelitian ini bermaksud menilai hubungan antara imunoekspresi bcl-2 dan imunoekspresi caspase-3 dengan respon kemoterapi CHOP. Metode Penelitian ini dilakukan secara retrospektif dengan desain analitik potong lintang terhadap 63 kasus LNH tipe sel B CD20 positif yang memenuhi kriteria penelitian, dari Januari 2009-Juni 2011 di Departemen Patologi Anatomik RSHS, Bandung. Kemudian dilakukan pulasan imunohistokima bcl-2 dan caspase-3, dan dihubungkan dengan respon kemoterapi dari data rekam medis. Hasil penelitian dianalisis statistik dengan uji Chi-square. Hasil Hasil penelitian ini adalah terdapat hubungan yang bermakna antara imunoekspresi bcl-2 yang lemah dengan baiknya respon kemoterapi CHOP (p=0,012), antara imunoekspresi caspase-3 yang kuat dengan baiknya respon kemoterapi CHOP (p=0,033), dan terdapat hubungan antara gabungan imunoekspresi bcl-2 yang lemah dan caspase-3 yang kuat dengan baiknya respon kemoterapi CHOP (p=0,009). Kesimpulan Ekspresi bcl-2 lemah dan imunoekspresi caspase-3 kuat menunjukkan respon kemoterapi CHOP yang lebih baik pada penderita LNH tipe sel B CD20 positif. Kata kunci : apoptosis, bcl-2, caspase-3, CD20, kemoterapi CHOP, LNH tipe sel B ABSTRACT Background Malignant lymphoma is malignancy originates from lymphoid tissue. B-cell type non-Hodgkin lymphoma (NHL) accounts for 90% from all lymphoma in the world. The incidence of B-cell type NHL approximately 4% of new cases every year. The chemotherapeutic agents CHOP (Cyclophospamide, Hydroxydaunorubicin, Oncovin, Prednison) is the standard treatment for NHL patient, with only 40%-50% complete response. In approximately 30% cases of NHL showed non-response with standard chemotherapy and underwent progressive disease until death. The effective chemotherapy response was shown by increasing number of cells that undergo apoptosis. Bcl-2 is a protein functions as anti-apoptotis, on the other hand caspase-3 has a role as excecutor caspase (pro-apoptotic). The aim of this study was to assess the association between bcl-2 and caspase-3 immunoexpression with CHOP chemotherapy response. Methods This is a retrospective study in 63 cases of B-cell type NHL which met the research criterias, using cross-sectional analytic design, at the Departement of Anatomical Pathology, Dr. Hasan Sadikin General Hospital in Bandung from January 2009 to June 2011. Immunohistochemistry for bcl-2 and caspase-3 were done, and then the clinical chemotherapy response were collected from the medical records. The result was analyzed using Chi-square. Results This study shows significant association between weak bcl-2 immunoexpression with good CHOP chemotherapy response (p=0.012), significant association between strong caspase-3 immunoexpression with good CHOP chemotherapy response (p=0.033), and significant association between combination of weak bcl-2 and strong caspase-3 immunoexpression with good CHOP chemotherapy response (p=0.009). Conclusion The weak bcl-2 immunoexpression and strong caspase-3 immunoexpression show good chemotherapy response in B-cell type LNH.

Abstract

Domestic chicken eggshells contain calcium and protein that could be useful in wound healing process. This research was conducted to determine whether domestic chicken eggshells can accelerate wound healing. Twenty one male Swiss-Webster mice  with 2 cm incision were divided into 3 groups. Negative control group were given Carboxymethyl cellulose 1% (CMC), positive control group were given feracrylum 1% (FER), and the eggshells group given domestic chicken eggshells powder (KT). Treatment and data mesurement was measured every day until  the 7th day. On the 7th  day the average length of the wound were analyzed and the skin tissue is taken for microscopic examination. Data analyzed using one-way ANOVA followed by Post Hoc Least Significant Difference (LSD) with p=0,05. On macroscopic examination, there were  highly significant differences between KT compared to CMC and highly significant differences between KT compared to FER. the average length of wound on the 7th day on KT 0,63 cm shorter than CMC 1,07 (p=0,000) and FER 0,81 cm (p=0,003). On microscopic examination, the degree of reepithelization on KT groups are severe, moderate for collagen density, fibroblasts density, subepithelial neutrophil density, degree of edema, and mild for angiogenesis. We conclude domestic chicken eggshells powder can accelerate wound healing. Key words: domestic chicken eggshells, incision wound, wound healing

Abstract

Antioksidan merupakan substansi yang dapat mencegah kerusakan sel akibat stres oksidatif. Hidrolisat protein dari kacang polong hijau (Pisum sativum) dengan bromelain (HPPHB) diharapkan meningkatkan kadar antioksidan superoxide dismutase (SOD) dan mampu mencegah kerusakan ginjal. Tujuan penelitian adalah mengetahui pengaruh HPPHB terhadap kadar SOD, kadar kreatinin plasma dan histopatologis ginjal tikus yang diinduksi Cisplatin. Penelitian dilakukan dalam dua tahap, pemberian HPPHB dosis 100, 200 dan 400 mg/kgBB/h selama 28 hari terhadap kadar SOD tikus jantan dan betina Sprague Dawley (SD) tanpa induksi dan tikus yang diinduksi Cisplatin dengan parameter kadar kreatinin plasma dan histopatologis ginjal dengan pewarnaan Hematoksilin Eosin (HE). Hasil menunjukkan kadar SOD kelompok tikus kontrol berbeda bermakna dan sangat bermakna dengan kelompok perlakuan. Hasil pemeriksaan kreatinin plasma menunjukkan terdapat perbedaan yang sangat bermakna (p<0,01) antara kontrol positip dengan kelompok dosis 400 mg/kgBB. Hasil analisis mikroskopis histopatologis parameter nekrosis: kelompok perlakuan dosis 200 menunjukkan paling sedikit nekrosis di antara ke tiga dosis,  berbeda signifikan dengan kontrol positip, maupun kontrol negatip (p<0,05). Parameter densitas sel mesangium, semua kelompok dosis perlakuan tidak berbeda signifikan dengan kontrol negatip maupun kontrol positip. Simpulan, HPPHB meningkatkan kadar SOD dan menunjukkan efek perbaikan kadar kreatinin plasma dan nekrosis sel tubulus ginjal tikus SD yang diinduksi Cisplatin.
