"Secara geografis Indonesia sangat berpotensi sekaligus rawan bencana alam. Beberapa dampak bencana alam yang ditimbulkan terhadap masyarakat adalah timbulnya cedera, depresi, dan penyakit. Ketiga hal tersebut berkaitan erat dengan sistem imun manusia. Untuk menanggulangidampak bencana, pemerintah(BPPT) hendak mengeluarkan suatu produk pangan baru yang berasal dari ektrak buah delima yang secara in vitro terbukti meningkatkan respon imun tubuh manusia. Diperlukan penelitian toksisitas oral akut dan subkronik produk pangan darurat BPPT tersebut.Penelitian ini menggunakan true experimental design dengan pemilihan sampel secara random alokasi. Pada uji toksisitas oral akut digunakan 5 ekor tikus jantan dengan pemberian dosis 9g/kg BB. Setelah 14 haritidak terdapat efek toksik yang bermakna dan tikus yang mati sehingga nilai LD50> 9 g/kg BB.Pada uji toksisitas oral subkronik digunakan 4 grup perlakuan (1 g/kg BB, 2 g/kg BB, 4 g/kg BB, kontrol) untuk tiap jenis kelamin dengan jumlah @10 ekor tikus. Pada setiap grup diberikan perlakuan, observasi, dan pengukuran berat badan secara berkala selama 90 hari.Pada akhir periode perlakuan dibandingkan hasil observasi makroskopik dan mikroskopik antar kelompok. Secara umum grup tikus dengan dosis 1 g/kg BB tidak menunjukan tanda toksisitas yang bermakna, grup tikus dengan dosis 2 g/kg BB mulai menunjukan gangguan pada fungsi organ, dan grup tikus dengan dosis 4g/kg BB telah mengalami kerusakan jaringan berdasarkan pemeriksaan histopatologi. Berdasarkan hasil tersebut maka NOEL (No Observed Effect Level) pada tikus jantan dan betina adalah 1 g/kg BB.

Located in ?The Pacific Ring of Fire?, it is irrefutable that Indonesia is vulnerable to natural disasters. Indeed, countless severe catastrophes result inthe emergence of closely-related human immune system problems, such as: injury, depression and illness. To deal with the issues, the Government (BPPT) has been planning meticulously to launch a new food product derived from pomegranate fruit extracts that can improve the human immune response system. It is then necessary to have further research onacute oral toxicity and sub-chronicoral toxicity of BPPT's emergency food product.

The study employed true experimental designmethodology as its principal and using randomize allocation sampling. A dose of 9 g/kg BB was given to five male ratsin an acute oral toxicity test. After 14 days, there were no significant toxic effects and no rat died. As such, the value of the LD50is > 9 g/kg BB. Another analysis was done in a sub-chronicoral toxicity test by using four treatment groups (1 g/kg BB, 2 g/kg BB, 4 g/kg BB, control) @ 10 rats for each sex.Foreachgroup, there were stringent monitoringas well asregular periodical body weight measurement within 90 days.

At the end of the treatment period, the results gathered from macroscopic and microscopic measurements were compared among groups. In general, group1 g/kg BB dose rats did not show significant signs of toxicity. Group 2g/kg BB dose rats started to show interference with the organ functions. As for the group4 g/kg BB dose rats, theyhad damaged tissue in histopathological examination. Based from these outcomes, it is clear that NOEL (No Observed Effect Level) in male and female rats is 1 g/kg BB."

"Kecacingan merupakan penyakit yang masih mengancam kesehatan. Kecacingan paling umum disebabkan nematoda usus diikuti schistosomiasis dan filariasis. Nematoda usus utama penyebab kecacingan adalah Ascaris lumbricoides. Penyebab utama filariasis adalah Wuchereria bancrofti (90% kasus). Infeksi kedua cacing tersebut dalam tubuh manusia menyebabkan peningkatan aktivitas sel Th2 dalam mensekresi IL-4 dan IL-5 yang akan mengaktifkan sel-sel imun lain untuk mengeliminasi parasit. Kedua jenis cacing ini hidup di tempat yang berbeda di dalam tubuh manusia.Karena itu, sangat menarik untuk diketahui apakah terdapat perbedaan antara respon imun adaptif selular yang timbul pada infeksi Ascaris lumbricoides yang hidup di lumen usus dan Wuchereria bancrofti yang hidup di jaringan.Penelitian dilakukan dengan desain cross sectional dengan menggunakan data dari penelitian utama berjudul "Pola Respon terhadap Antigen Tetanus Toxoid dari Bayi yang Lahir dari Ibu dengan Infeksi Cacing". Respon imun selular 3 kelompok penelitian, yaitu terinfeksi Ascaris lumbricoides, Wuchereria bancrofti dan sehat dibandingkan dengan melihat data kadar sitokin IL-5 yaitu sebelum distimulasi, setelah distimulasi antigen BmA dan setelah distimulasi dengan antigen Ascaris lumbricoides.Dari 286 data wanita hamil yang tersedia dari penelitian utama, didapatkan 82 data yang memenuhi kriteria penelitian dan dianalisis. Hasil penelitian menunjukkan profil sitokin IL-5 sebelum distimulasi antara kelompok kasus terinfeksi Ascaris lumbricoides dan Wuchereria bancrofti tidak berbeda bermakna (p=0,60). Kadar IL-5 setelah distimulasi antigen BmA dan Ascaris lumbricoides ketiga kelompok penelitian pun tidak berbeda bermakna. (p=0,07;p=0,92). Maka disimpulkan bahwa tidak ada perbedaan bermakna antara respon imun adaptif selular infeksi Ascaris lumbricoides dan Wuchereria bancrofti pada ibu hamil.

Worm infection is one of diseases which still harm population's health. The most common worm infection is caused by intestinal nematode followed by schistosomiasis, and filariasis. The most common intestinal nematodes causing worm infection is Ascaris lumbricoides. The main cause of filariasis is Wuchereria bancrofti (90% cases). The two nematodes infection in human is marked by increase activity of Th2 cells which secrete IL-5 and IL-4 to activate other cells to eliminate worms. The two nematodes live in different place in human.

Because of that, it is very interesting to know if there were differences of adaptive cellular immune response between the two worms infection. The study design was cross sectional and the data was from study titled ?Immunological Consequence of Vaccination Tetanus Toxoid in Indonesian Children Born to Mothers Chronically Infected with Helminthes?. Adaptive cellular immune response between three groups, infected with Ascaris lumbricoides, infected with Wuchereria bancrofti, and health, were compared using IL-5 profile data before stimulation, after BmA stimulation and after Ascaris lumbricoides antigen.

From 286 data, there were 82 data met the study criteria for analysis. The result showed that there was no significant difference of adaptive cellular immune response, which showed by IL-5 profile between group with infection Ascaris lumbricoides and Wuchereria bancrofti before stimulation (p=0,6). After stimulated by BmA and Ascaris lumbricoides antigen, there was no significant difference of IL-5 profile between the three groups. (p=0,07; p=0,92). In conclusion, there was no significant difference of adaptive cellular immune response between Ascaris lumbricoides infection and Wuchereria bancrofti infection in pregnant women."

"Bahan pangan darurat BPPT merupakan makanan padat gizi berbentuk biskuit yang dikemas secara tertutup untuk dikirimkan ke tempat-tempat bencana alam. Dalam bahan pangan tersebut terkandung polifenol yang telah terbukti secara invitro dapat meningkatkan respon imun. Untuk dapat mengaplikasikan dalam kehidupan masyarakat, bahan ini perlu melalui uji eksperimental hewan coba terlebih dahulu. Uji eksperimental yang dilakukan terhadap 30 ekor mencit yang dibuat lapar. Setelah dua minggu berada dalam kondisi kelaparan, enam ekor mencit diambil datanya, mencit lainnya kemudian dibagi ke dalam dua kelompok perlakuan, yaitu kelompok yang diberi produk pangan darurat BPPT dan kelompok yang diberi imunomodulator Phyllanthus niruri, suatu produk imunomodulator yang telah di pasarkan di Indonesia. Enam mencit dari masingmasing kelompok diperiksa setelah mendapat perlakuan selama dua dan empat minggu. Pada penelitian ini tidak ditemukan perbedaan yang bermakna (p>0,05) pada perbandingan perubahan jumlah leukosit, limfosit, netrofil segmen, dan jumlah IgG total antara mencit yang mendapat asupan pangan darurat BPPT dengan mencit yang mendapat asupan Phyllanthus niruri baik selama dua dan empat minggu. Oleh sebab itu, peneliti menyimpulkan bahwa produk pangan darurat BPPT memiliki efek yang sama baiknya dengan Phyllanthus niruri dalam meningkatkan respon imun mencit kelaparan dengan indikator jumlah leukosit, perubahan hitung jenis, dan jumlah IgG total setelah pemakaian dua maupun empat minggu.

BPPT emergency food is nutrient-rich cookies which are packaged in a closed session to be sent to places of natural disasters. This product contains polyphenol that has been shown to enhance immunity response in in-vitro experimentation. In order to be applicable in public life, this product needs to be experimented on animals.

Experimental tests were conducted on thirty mice which were made to be hungry. After two weeks in a state of starvation, six mice were taken to be examined, while the rest were divided into two groups, one group was given BPPT emergency food and the other group was given Phyllanthus niruri, an immunomodulator which has been marketed in Indonesia. After two weeks, six mice from each group were taken for examination and the rest were examined two weeks after the first test.

The result found no significant difference (p> 0.05) on changes number of leukocytes, lymphocytes, neutrophils segments, and total IgG between mice that received BPPT emergency food and mice that received Phyllanthus niruri after being treated for two and four weeks. Therefore, researchers concluded that the BPPT emergency food products has similar effect with Phyllanthus niruri in enhancing starving mice immunity response, indicated by the number of leukocytes, differential count of leukocyte, and total amount of IgG."

Dengan teknik Western blot didapatkan pula reaksi negatif antara AFP tikus dengan antibodi anti-albumin tikus (titer 800.000). Dengan demikian dapat disimpulkan bahwa tidak terdapat reaksi imun silang antara AFP dan albumin tikus."

"Penggunaan DMPS sebagai filler material berdasar pada anggapan bahwa DMPS merupakan biomaterial yang bersifat inert terhadap sistem imun tubuh. Berbagai kasus pada individu dengan injeksi DMPS memicu timbulnya granuloma yang kemudian diikuti oleh fibrosis. Berbagai kemungkinan penyebab mengenai kemunculan respon imun akibat DMPS pun muncul. Mulai dari kontaminasi oleh komponen bakteri, seperti LPS, cara injeksi yang tidak tepat, volume DMPS yang diinjeksikan tidak sesuai hingga mekanisme seluler, seperti oksidasi DMPS, yang menyebabkan molekul tersebut menjadi imunogenik.Data yang didapat dari penelitian ini akan mencoba menjelaskan mekanisme respon imun seluler dari resipien terhadap DMPS yang diinjeksikan dengan metode secara in vitro untuk mengetahui gambaran respon imun yang terjadi di dalam tubuh akibat pajanan DMPS hingga dapat memicu timbulnya granuloma hingga fibrosis. PBMC diambil dari pasien normal dan pasien dengan granuloma akibat injeksi DMPS. Kemudian, dikultur selama 72 jam dengan kelompok perlakuan RPMI sebagai kontrol negatif, PHA dan LPS sebagai kontrol positif, DMPS dan DMPS dengan penambahan plasma autolog.Tujuan dari kultur PBMC tersebut adalah untuk mendapatkan gambaran aktivitas sitokin TNF-a, IFN-g, IL-6, IL13 dan IL-10 yang diperoleh dengan analisis menggunakan Milliplex map kit Luminex serta proliferasi PBMCdengan menggunakan pewarnaan acridine orange. Tidak ada peningkatan proliferasi limfosit maupun monosit yang signifikan (p>0,05) pada kelompok perlakuan DMPS, baik pada pasien normal maupun pasien dengan granuloma. Peran plasma autolog pun tidak teramati dalam meningkatkan proliferasi pada kedua sel. Meskipun demikian, plasma autolog berperan dalam peningkatan aktivitas TNF-a dan IL-6 secara signifikan (p<0,05) sebagai respon terhadap pajanan DMPS, baik pada pasien normal maupun pasien dengan granuloma.Data penelitian ini menunjukkan bahwa DMPS mampu memicu timbulnya inflamasi yang dimediasi oleh aktivitas TNF-a dan IL-6 dan sangat bergantung pada protein plasma setiap individu, meskipun data berupa proliferasi PBMC belum dapat menggambarkan gambaran respon imun terhadap DMPS.

The use of DMPS as a filler material based on the assumption that DMPS is a biomaterial that is inert to the immune system. Various cases in individuals with DMPS injection, trigger granuloma formation, followed by fibrosis. Possible causes of the emergence of the immune response due to DMPS are appeared. Start from contamination by bacterial components, such as LPS, improper injection method, the volume of injected DMPS does not conform, and cellular mechanisms, such as oxidation of DMPS, which causes that molecule becomes immunogenic.

The data obtained from this study may try to explain the mechanism of cellular immune response of DMPS-injected recipients with in vitro-based method to get the description of immune responses that occurs in the body due to exposure of DMPS which can lead to granuloma formation, followed by fibrosis. PBMC is taken from normal patients and patients with granulomas due to injection of DMPS. And then, it was cultured for 72 hours with RPMI treatment as a negative control, PHA and LPS as a positive control, DMPS and DMPS with the addition of autologous plasma.

The purpose of the PBMC culture was to describe the activity of TNF-a, IFN-g, IL-6, IL13 and IL-10, which were obtained by analysis using Milliplex map kit Luminex and PBMC proliferation using acridine orange staining. There is no increase in proliferation of lymphocytes and monocytes were significantly (p> 0.05) in the DMPS-treated group, both in normal patients and patients with granulomas. The role of autologous plasma was not observed in the increase both cell proliferation. Nonetheless, autologous plasma had a role in the increased activity of TNF-a and IL-6 significantly (p <0.05) in response to exposure DMPS, both in normal patients and patients with granulomas.

The data of this study indicated that DMPS is able to trigger inflammatory activity mediated by TNF-a and IL-6 and it was very dependent on each individual plasma proteins, although the data from proliferation of PBMC has not been able to describe immune response against DMPS."

"PendahuluanStomatitis Aftosa Rekuren (SAR) adalah suatu penyakit mulut yang paling sering ditemukan kini amat mengganggu penderitanya karena hilang tirnbul (rekurest) sehingga dapat mengganggu fungsi pengunyahan (1;2). SAR biasanva mengenai jaringan lunak yang tidak berkeratin, bentuknya bulat, dikelilingi "halo" berbatas jelas dan terasa sakit (2,3,4). Etiologi SAR sampai saat ini belum diketahui dengan pasti, namun ada beberapa faktor predisposisi yang diduga turut berperan pada putogenesisnya, antara lain faktor genetik, hormonal, imunologis, psikologis, infeksi mikroorganisme, derisiensi vitamin ataupun allergi (2,3,4,5), Karen belum diketahui penyebab utamanya maka bagaimana mekanisme sampai terjadinya SAR (patogenesis) secara pasti belum terungkap. Oleh karena itu penanganan SAR yang telah diupayakan selama ini belum mencapai hasil yang optimal. Seiring dengan kemajuan di bidang imunologi maka beberapa penelitian akhir-akhir ini menemukan adanya ketidakseimbangan imunologis pada penderita SAR yaitu dengan ditemukannya perubahan proporsi subpopulasi limfosit di daerah tepi oleh Leiner (6,7,8) dan ternyata perubahan tersebut semakin nyata pada SAR tipe mayor (9)."

T regulatory cells perhaps play the important roles to suppress the immune respons to microorganisms was also done.Results: The profile of the immune respons of the people living in the unslum area is significantly more inflamatif than that in the slum area. The ratio of pro anti inflammation cytokines TNF IL 10 of the people living in the unslum area is significantly higher than that in the slum area. This is marked by increasing of oxLDL accumulationis that is the important point of the low protection to oxLDL of the people living in the unslum area p 0.01 . T regulatory cell may suppress the proliferation in the PBMC culture for the people living in the slum area marked by increasing not only the expression of IL 10 cytokines but also the sum of T regulatory sells p 0.01 significantly.Conclusion: The immune respons of the people living in the unslum area is more inflamatif and responsive to malaria, BCG vaccine and oxLDL. The character of macrophage of the people living in the slum area is marked by the low ratio of pro anti inflammation cytokines TNF IL 10 to malaria, BCG vaccine and oxLDLstimulations. T regulatory cell may suppress the proliferation in the PBMC culture for the people living in the slum."

"[ABSTRAKPendahuluan: Di Indonesia belum ada penelitian tentang injeksi silikon dan komplikasinya, walaupun kasusnya banyak. Patogenesis granuloma silikon masih belum jelas. Beberapa penelitian mengemukakan peran sel T dan sitokin, namun belum ada yang meneliti tentang toleransi imun.Metode: Penelitian ini merupakan penelitian deskriptif analitik meliputi rancangan potong lintang membandingkan 3 kelompok, yaitu 31 jaringan granuloma dan 31 kulit submental pasien dengan suntikan silikon di dagu (kasus) dan 37 kulit normal (kontrol), terhadap gambaran klinis, histopatologis, dan respons imun melalui ekspresi sitokin TNF-a, IFN-g, IL-10, enzim IDO, serta sel Treg (CD4+CD25+); Penelitian eksperimental membiakkan darah penuh kasus dan orang normal, pada RPMI, dan RPMI yang distimulasi PHA, dan silikon. Dilanjutkan dengan mengukur kadar sitokin TNF-a, IFN-g, IL-10 dan IDO supernatan biakan darah. Penelitian dilakukan di klinik spesialis JMB, FMIPA, FKUI, FKUNAIR, dan lembaga Eijkman, tahun 2012 - 2014.Hasil Penelitian: Sebanyak 31 pasien granuloma akibat suntikan silikon di dagu umumnya datang berobat 12,5 tahun setelah penyuntikan, perubahan bentuk dagu terjadi pada tahun ke-4, perubahan warna pada tahun ke-5. Kadar sitokin proinflamasi di supernatan biakan darah lebih tinggi pada pasien granuloma daripada normal. Terdapat korelasi bermakna antara TNF-a di supernatan biakan darah dengan ekspresi TNF-a di jaringan granuloma. Enzim IDO, Treg, IL-10 di kulit submental berkorelasi bermakna dengan sitokin di granuloma. Sitokin anti inflamasi berperan pada kulit submental. Rasio TNF-a/IL-10 di supernatan biakan darah berkorelasi terbalik dengan ekspresi sel Treg di granuloma, membuktikan fungsi Treg sebagai toleransi imun, bekerja melalui IL-10. Enzim IDO di granuloma berkolerasi bermakna dengan rasio TNF-a/IL-10 di supernatan biakan darah dan Treg kulit submental.Simpulan: Enzim IDO bekerja sama dengan fungsi sel Treg dalam toleransi imun pada granuloma akibat suntikan silikon. TNF-a di supernatan biakan darah dan sitokin anti inflamasi di kulit submental dapat dijadikan prediktor untuk menilai respons imun yang terjadi akibat suntikan silikon.;
