Pengaruh Pemberian Ekstrak Phyllanthus Niruri Linn terhadap Infiltrasi Limfosit dan Ekspresi Perforin pada Kanker Kolon Tikus Sprague-Dawley

The effect of Phyllanthus niruri Linn extract on lymphocytes infiltration and perforin expression in colon cancer of Sprague-Dawley RatBackground: Colon cancer treatment currently involves immunotherapy that aims to improve the quality of life and survival of patients. Phyllanthus niruri Linn (P. niruri L) may act as an immunomodulator, but its potency in antitumor immune responses has not been revealed. The study was conducted to evaluate the differences between the immunological status of rats suffering colon cancer which were not given to those given the extract of P. niruri L.Methods: The study was randomized posttest-only control group design. Samples were 30 Sprague-Dawley male rats, bodyweight 170-220 gr which induced by 1.2 DMH 30 mg/kgBW subcutaneously. On the weeks 9, 11 and 13, four induced rats each week were sacrified to detect the development of colon cancer. On the weeks of 13th all of 4 rats were developed colon cancer, so the induction were stopped. The rest of 18 induced rats were randomly into two groups: without P. niruri L or positive control (K+)=9 rats and given P. niruri L extract 13.5 mg/kg orally or X group=9 rats. After 19th week all of rats were then terminated and tumor lesion of colon were processed hystophatologically. The tissues of colon cancer were stained by H&E for evaluate the lymphocytes infiltration and immunohistochemistry monoclonal antibody anti-perforin for perforin expression. Non pairs t-test was used with considered significant if p<0.05.Results: The mean of lymphocytes infiltration of the group X was 401.89±70.19, it was higher compared to K+ 191.89±50.68 (p=0.000). The mean percentage of perforin expression of group X was 39.00±1.80%, it was higher compared to K+ 23.00± 3.00% (p=0.000). Conclusion: The extract of P. niruri L increases immunologic status through mechanism of lymphocytes infiltration and perforin expression elevation of colon cancer in animal mode

Ekstrak Phyllanthus Niruri Linn, Pertumbuhan Tumor dan Proliferasi Sel Kanker Kolorektal: Studi Eksperimental pada Tikus Sprague-Dawley yang Diinduksi 1,2 DMH

Effect of Phyllanthus niruri Linn extract on tumor growth and cell proliferation of colorectal cancer: experimental study in 1.2 DMH-induced Sprague-Dawley ratsBackground: The development of chemotherapy for colorectal cancer (CRC) is so very advanced, however, the survival of patients has not been satisfactory, therefore, the current therapy also involve immunotherapy. Phyllanthus niruri Linn (P. niruri L) may act as an immunomodulator and anticancer, but its potency has not been revealed. Study was conducted to confirm the effects of P. niruri L extract in the treatment of CRC.Method: The study was randomized posttest-only control group design. Samples were Sprague-Dawley male rats, bodyweight 170- 220 gr, were divided into two groups: non induced or negative control (K-) consisted of 9 normal rats, and induced by 1.2 DMH 30 mg/kgBW subcutaneously group consisted 30 rats. On the weeks 9, 11 and 13, four induced rats each week were sacrified to detect the development of CRC. On the weeks of 13th all of 4 rats were developed CRC, so the induction were stopped. The rest of 18 induced rats were randomly into two groups: without P. niruri L or positive control (K+)=9 rats and given P. niruri L extract 13.5 mg/kg orally or X group=9 rats. After 19th week all of rats were then terminated and tumor lesion of colon were examined macroscopically and hystophatologic tissues were stained with AgNORs for evaluate the cells proliferation. Oneway Anova and Post Hoc LSD test for the growth of colon tumor and non pairs t-test for cell proliferation were used. Considered significant if p was <0.05. Result: There was no tumor growth on K- group, while for K+ was 83.33±14.34% and on X was 40.44±13.23% (p=0.000). The mean of AgNORs on K+ was 4.60±0.55 while on X was 2.25±0.39 (p=0.000).Conclusion: The extract of P. niruri L suppress the tumor growth and cell proliferation of CRC

Pengaruh Pemberian Vitamin C terhadap Aktiitas Fagositosis Makrofag dan Kadar Vitamin C dalam Cairan Intraperitoneal Mencit Balb/C dengan Sepsis

Latar belakang : Sepsis masih menjadi permasalahan dalam praktek klinis karena angka mortalitas masih tinggi. Penelitian bertujuan mengetahui pengaruh dosis bertingkat vitamin C yang dibutuhkan untuk mencapai aktivitas fagositosis optimal makrofag mencit sepsis. Metode : Penelitian ini merupakan uji laboratoris mencit Balb/C dengan pendekatan the post test only controlled group design, 20 ekor mencit sepsis dibagi 4 kelompok: kelompok kontrol (K); kelompok perlakuan mendapat vitamin C 0,52 mg/hari (P1); vitamin C 1,04 mg/hari (P2); vitamin C 2,6 mg /hari (P3) selama 3 hari, kemudian diperiksa kemampuan fagositosis makrofag dan kadar vitamin C intraperitoneal. Tingkat aktivitas fagositosis makrofag dan kadar vitamin C intraperitoneal dianalisis dengan ANOVA dilanjutkan dengan Bonferroni test, dan korelasi keduanya diuji dengan uji korelasi Spearman. Hasil : Terdapat perbedaan bermakna pada kemampuan fagositosis makrofag dalam kelompok (p&lt;0,05). Uji antar kelompok menunjukkan: K–P1 (p&lt;0,001), K–P2 (p&lt;0,001), K–P3 (p&lt;0,001),&nbsp;&nbsp; P1–P2&nbsp;&nbsp; (p&lt;0,001),&nbsp;&nbsp; P1–P3&nbsp;&nbsp; (p&lt;0,001),&nbsp;&nbsp; tetapi&nbsp; &nbsp;tidak didapatkan perbedaan yang bermakna antara P2-P3 (p=0,48). Terdapat perbedaan bermakna kadar vitamin C intraperitoneal K–P2&nbsp; &nbsp;(p&lt;0,001),&nbsp; &nbsp;K–P3&nbsp; &nbsp;(p&lt;0,001),&nbsp; &nbsp;P1–P2&nbsp; &nbsp;(p=0,003),&nbsp; &nbsp;P1–P3 (p&lt;0,001), P2-P3 (p&lt;0,001), kecuali pada kelompok K–P1 (p=0,131). Didapatkan korelasi positif antara kadar vitamin C intraperitoneal dengan fagositosis makrofag (r=0,58 ; p&lt;0,001). Simpulan : Terdapat peningkatan signifikan pada fagositosis makrofag dan kadar vitamin C intraperitoneal pada mencit Balb/C dengan sepsis yang diberi vitamin C. Dosis ideal vitamin C adalah 1,04 mg/hari, dan kadarnya meningkat sesuai dosis yang diberikan. Kata kunci: Sepsis, vitamin C, fagositosis makrofag, vitamin C intraperitoneal
