"[ABSTRAKBCG telah digunakan sebagai upaya mencegah infeksi tuberculosis selama lebih dari 90 tahun. Penelitian ini dilakukan untuk melihat efek pemberian vaksin BCG melalui rute subkutan di area dorsal leher dan paha pada mencit galur Swiss sekaligus menguji potensi pasak bumi (PB) sebagai imunomodulator setelah imunisasi BCG dengan mengukur IgG1 dan IgG3 menggunakan metode ELISA. Penelitian ini merupakan bagian dari proyek penelitian mengkaji potensi ekstrak akar pasak bumi pada beberapa infeksi pathogen intraseluler. Hasilnya pemberian vaksin BCG melalui rute subkutan di area leher lebih efektif (p<0.05) meningkatkan kadar IgG1 (OD kelompok air 2.162±0.231; kelompok PB 2.138±0.214) dan IgG3 (OD kelompok air 2.564±0.286; kelompok PB 2.521±0.228) pada mencit dibandingkan kadar IgG1 (OD kelompok air 0.817±0.101; kelompok PB 0.796±0.207) dan IgG3 (OD kelompok air 1.290±0.104; kelompok PB 1.260±0.093) pada vaksinasi BCG secara subkutan di area paha. Sementara itu potensi ekstrak akar pasak bumi dalam memodulasi produksi IgG1 dan IgG3 paska injeksi BCG belum terlihat pada percobaan ini.

ABSTRACTTuberculosis is a deadly infectious disease that occurs mainly in developing countries, including Indonesia. Preventive efforts by BCG vaccination to improve the immune response is still not maximum. Factors that affect the success of vaccine are the host immune system, the host genetic and the quality/quantity of the vaccine. Indonesia is rich in medicinal plants, one of those is Pasak Bumi (Eurycoma longifolia Jack) that is widely used as antimalaria and to improve immunity. The research assessed the effects of extracts of Pasak Bumi roots as immunomodulator by measuring IFN-ɣ, TNF-α and IL-10 on mice that were given with BCG vaccine. In vivo and in vitro experiments of mice blood cultured in RPMI medium stimulated with PHA and BCG. The result has shown no significant difference (p≥0,05) among the treatment group, result of median values has shown the effect of Pasak Bumi extract to an increase of TNF-α, and has no effect on the production of IFN-γ and IL-10 in mice vaccinated BCG. Extract of pasak bumi roots affects the immune response of mice that have got BCG vaccine, although it has no significant meaning., Tuberculosis is a deadly infectious disease that occurs mainly in developing countries, including Indonesia.

ABSTRACTThe ability of Mycobacterium tuberculosis to manipulate and evade host?simmune response is a challenge in finding an effective therapy and vaccination.The purpose of this research were to investigate the potency of methanol extractof the roots of Eurycoma longifolia Jack as immunomodulators for male whitemice vaccinated with BCG, as well as to analyze the increase of proinflammatorycytokines associated with IgA and IgG production. Plasma were taken before andafter BCG vaccination from 18 mice, that were divided into 2 groups; treatmentand control. IgA, IgG, TNF-! and IL-10 levels were measured by using ELISA.The results showed that the enhancement of IgA group with water (0,33±0,16)was higher than group with pasak bumi (0,30±0,30). On the other hand theenhancement of IgG group with pasak bumi (0,38±0,25) was higher than groupwith water (0,29±0,35). The ratio of TNF-!/IL-10 group with pasak bumi(0.46±0.07) was higher than group with water (0.41±0.05).

Efek Imunomodulator, dinilai terhadap rata-rata MFI TNF-α, IFN-γ dan IL-10 kelompok yang diterapi ekstrak akar pasak bumi dibandingkan kelompok kontrol secara berturut-turut ± 14,5 : ± 6,2; ±9,2 : ±25,38; ±29,6 : ±14,75.Terdapat korelasi positif penghambatan pertumbuhan parasit dengan nilai TNF-α (r = 0,612, p = 0,06), Korelasi negatif Penghambatan pertumbuhan parasit dengan nilai IFN-γ (r = -0,092, p = 0,814), Korelasi positif penghambatan pertumbuhan parasit dengan nilai IL-10 (r = 0,276, p = 441). Terdapat korelasi negatif antara nilai TNF-α dengan IFN-γ (r = - 0,699, p = 0,036), korelasi positif antara nilai TNF-α dengan IL=10 (r = 0,350, p = 0,355) Kesimpulan ekstrak akar pasak bumi mempunyai efektivitas sebagai antimalaria, dengan mempengaruhi peningkatan sitokin TNF-α dan IL-10, tetapi tidak pada IFN-γ

Background. Malaria is still a health issues. Malaria is caused by parasites of the genus Plasmodium. An immune response actually has contribution against infection malaria, among others proinflamation and antiinflamation cytokine play an important role. Extract of pasak bumi root is a drug traditional as antimalarial. Pasak bumi root is also immunomodulator. The aim of this research is to analyze of an extract of methanol of Pasak bumi root as antimalarial against the level of a proinflamation and antiinflamation cytokines on mice is infected by P. berghei Methods. 5 mouse are infected by P. berghei, are given extract of pasak bumi root with dose 60 mg/kg BB. Antimalaria is shown by apusan tipis and apusan tebal. Proinflamasi and antiinflamasi is examined by bead based multiplexing technique.Result. Antimalarials activity has its obstruent against parasitic about 88,78% (p = 0,007) and The average growth of the parasitic 0,03% (p = 0,001). Effect of immunomodulator, mean of MFI TNF-α, IFN-γ and IL-10 on a group that is in therapy is compared on an group that are not in therapy respectively ± 14,5 : ± 6,2; ±9,2 : ±25,38; ±29,6 : ±14,75. There is a positive correlation between Growth inhibitor of parasitic and TNF-α. (r = 0,612, p = 0,06). There is a negative correlation between growth inhibitor of parasitic and IFN-γ (r = -0,092, p = 0,814) and there is a positive correlation between growth inhibitor of parasitic and IL-10 (r = 0,276, p = 0,441). There is a negative correlation between score of TNF-α and IFN-γ (r = -0,699, p = 0,036) between TNF-α. and IL-10 (r = 0,350, p = 0,355). Conclusions. An extract of Pasak bumi root a have an antimalarial the effectiveness and influence to TNF-α and IL-10 but not on IFN- γ"

"Indonesia telah mengimplementasikan program imunisasi nasional yang mencakup 5 imunisasi dasar, termasuk campak, namun, penyakit campak masih menjadi salah satu penyebab utama kematian pada anak.

Seratus lima puluh dua responden dari 200 memiliki pengetahuan yang buruk, 114 responden bersikap positif dan 188 responden memvaksinasi anak mereka dengan vaksin campak. Tidak ada hubungan signifikan antara tingkat pendidikan orang tua dan pengetahuan orang tua serta pada hubungan antara sikap orang tua dan perilaku terhadap vaksin campak. Terdapat hubungan signifikan antara pengetahuan orangtua dan perilaku dari vaksin campak dengan nilai p 0.009 dan odds ratio sebesar 5.01. Faktor lain; campur tangan pasangan/keluarga, kepercayaan, kekhawatiran terhadap efek samping dapat mempengaruhi perilaku orang tua terhadap vaksin campak.
