Ruang lingkup dan cara penelitian: Metilprednisolon (MPL) merupakan glukokortikoid yang berperan penting dalam respon imun spesifik yaitu efek supresi terhadap sel limfosit T, sehingga digunakan untuk mencegah rejeksi pada pasta transplantasi organ. Untuk pencegahan tersebut diperlukan metilprednisolon dosis tinggi untuk jangka pemberian cukup lama yang dapat menyebabkan efek samping obat yang berat yaitu efek imimosupresi yang kuat. Obat yang diinkorporasikan ke dalam liposom terbukti dapat memberikan efek yang lebih kuat dibandingkan obat babas tetapi MPL tidak terinkorporasi dengan baik dalam liposom sehingga disintesis MPLP. Metilprednisolon palmitat (MPLP) adalah senyawa yang berhasil diinkorporasikan ke dalam liposom membentuk liposom metilprednisolon palmitat (LMPLP). Metilprednisolon palmitat diharapkan dapat menurunkan efek samping yang ditimbulkan. Penelitian ini bertujuan untuk mengetahui efek supresi liposom metilprednisolon palmitat terhadap proliferasi limfosit T subpopulasi CD4+ dan CDS+ yang distimulasi oleh concavalin A. Limfosit dipisahkan dari darah perifer manusia, kemudian dikultur dengan pemberian LMPLP pada konsentrasi 0,4 mM, 0,1 mM dan 0,025 mM dibandingkan MPL pada konsentrasi yang sama. Jumlah limfosit hasil kultur dihitung menggunakan kannar hitung improved Neubauer yang diwarnai dengan trypan blue 0,25 %. Selanjutnya limfosit T subpopulasi CD4+ dan CDS+ dihitung menggunakan antibodi monokional yang dilabel dengan zat warna fluorescein isothiocyanate dan phycoerythrin memakai low-cytometer. Hasil dan kesimpulan: Hasil kultur limfosit in vitro, pemberian LMPLP maupun MPL menyebabkan penurunan jumlah limfosit yang bermakna dibandingkan liposom atau kontrol RPMI, sedangkan pemberian LMPLP menunjukkan kecenderungan memberikan efek supresi terhadap proliferasi limfosit T yang lebih besar dibandingkan MPL walaupun secara statistik tidak berbeda bermakna (p > 0,05). Pemberian LMPLP maupun MPL pada konsentrasi 0,4 mM, 0,1 mM dan 0,025 mM tidak menunjukkan penurunan jumlah sel limfosit T subpopulasi CD4- maupun CD8+ yang berbeda bermakna (p > 0,05). Liposom metilprednisolon palmitat lebih menekan proliferasi sel CD84 dibandingkan CD4. Sedangkan lerhadap rasio jumlah sel limfosit T subpopulasi CD4+/CD8+ diperoleh dosis optimal pada pemberian LMPLP konsentrasi 0,1 mM.
Scope and methods: Methylprednisolone is a glucocorticoid which is very important in specific immune response, especially in suppression effect to T lymphocyte and it has been used to prevent the rejection of organ transplantation. For that purpose, a high dose of methyprednisolone was used and in long term therapy may have a side effect such strong immunosuppression. Drugs incorporating in liposome give more strong effect that free drugs, but methyprednisolone not good incorporating in liposome. So methylprednisolone palmitate (MPLP) was sinthetized for that purpose. Methylprednisolone palmitate was successfully incorporate in liposome as a liposome methylprednisolone palmitate (L-MPLP). Liposome methylprednisolone palmitate was expected has minimum side effect. The aim of this study is to explore to know the suppression effect of L-MPLP to the subpopulation of CD4+ and CDs+ T lymphocyte proliferation which have been stimulated by concanavalin A. Lymphocyte was isolated from human peripheral blood and cultured in L-MPLP and MPL at the dose of 0,4 mM, 0,1 mM and 0,025 mM. The number of lymphocyte was counted by improved Neubauer and stained with 0,5% tryphan blue. CD4+ and CDs subpopulation of lymphocyte was counted by monoclonal antibody labelled by fluorescein isothiocyanate and phycoerythrin using flow-cytometer. Result and summary: Lymphocyte culture in vitro after administration of L-MPLP or MPL decreased number of lymphocyte significantly compared to liposome or RPMI as control. Although the administration of MPLP showed tendency of the reduction of the presentation of more than MPL but statistically not significance (p > 0,05). The administration of L-MPLP or MPL at the dose of 0,4 mM, 0,1 mM and 0,025 mM not showed a significance decreased of CD4+ and CDs+ subpopulation of T lymphocyte. The has administration of L-MPLP or MPL was not changing CD4+ and CDs+ subpopulation T lymphocyte. Liposome methylprednisolone palmitate could be suppressed the proliferation of CDC more than CD4+ subpopulation T lymphocyte. The optimal dose of L-MPLP to decrease the ratio CD4+ and CDs+ subpopulation T lymphocyte was 0,1 mM.

ABSTRACT
Peripheral blood lymphocytes from 5 Juvenile Periodontitis /JP, 27 Rapidly Progressive Periodontitis /RPP patients and 10 healthy subjects were examined using a panel of monoclonal antibodies and fluorescence flow cytometry. The relative counts of CD3+ (T) cells, CD4+(T helper /Th) cells, CD8+ (T suppressor /Ts or T cytotoxic /Tc) cells, CDI9+ (B) cells, and CD16+CD56+ (Natural Killer /NK) were assessed, and the CD4+lCD8+ (Th / Ts) ratio was calculated. In the JP patients the % proportion of T cells (62.4 ± 6.1887 vs 69.8 ± 5.6332) and NK cells (21.4 ± 7.37 vs 12.9 ± 6.94) were statistically significant difference to the control group. In the RPP patients the % proportion of CD3+ cells (61.7407 ± 9.3504 vs 69.8 ± 5.6332), CD4+ cells (31.04 ± 7.30 vs 37.7 ± 4,92) and NK cells (20.7 ± 8.85 vs 12.9 ± 6.94) were also statistically significant difference to the control group. But the CD4+/CD8+ (Th/Ts) ratio was not statistically significant in both groups. These results indicate that defect of immunoregulation and subpopulation lymphocyte function of Inclonisian patients which is clinically local as JP or RPP lesions. could detected systemically in their peripheral blood. Beside that, immunobiological characteristics between JP Arid RPP diseases compared to its control group have differed in Th cells subpopulation proportion.

ABSTRACT
A study was done to investigate the number and function of T cells of underfive children in Kelurahan Kramat, Kecamatan Senen, Jakarta Pusat. Grouping of samples was done based on weight-for-age, into well nourished (normal) children as control, mild-moderate PEM and severe PEM. The number of each group was 15.

The relative number of T cells in mild-moderate PEM and severe PEM were significantly reduced compared to the normal group (P <0.01 , See Figure 13). The relative number of blast-transformation of the severe PEM group compared with the mild-moderate PEB and the severe PEM with the normal group were not significantly different (P>0.05, See Figure 15). The total serum protein in mild-moderate PEM and severe PEM were not significantly different compared to the normal group (P> 0.05, See Figure 16). The protein intake in mild-moderate PEM and severe PEM were significantly reduced compared to the normal group (P<0.01, See Figure 17). The energy intake in mild-moderate PEM and severe PEM were significantly reduced to the normal group (P<0.01, See Appendix 11).

From the facts mentioned above it can be assumed strongly that: Lower protein intake in combination with lower energy intake in mild-moderate PEM and severe PEM are most probably very important factors that cause the reduction of T lymphocyte number in both moderate PEM as well as in severe PEM.

Sepsis merupakan penyakit umum di perawatan intensif dan hampir 1/3 pasien yang dirawat di ICU adalah pasien sepsis. Banyak penelitian dilakukan untuk mencari penanda sepsis yang handal dan jumlah apoptosis limfosit mulai banyak diteliti sebagai penanda sepsis. Apoptosis limfosit terjadi mulai 24 jam pertama setelah onset sepsis. Saat ini belum terdapat data yang menunjukkan dapat digunakannya jumlah apoptosis limfosit sebagai penanda prognostik sepsis. Tujuan penelitian ini adalah mengetahui dapat tidaknya jumlah apoptosis limfosit digunakan sebagai penanda prognostik pada pasien sepsis berat

Desain penelitian adalah uji prognosis secara prospektif, terdiri dari 30 pasien sepsis berat dibagi berdasarkan mortalitas 14 hari, yaitu 15 pasien hidup dan 15 pasien meninggal. Diagnosis sepsis berdasarkan modifikasi definisi sepsis oleh International Sepsis Definitions Conference 2001. Jumlah apoptosis limfosit dihitung menggunakan metode flowcytometry dengan reagen antibodi monoklonal CD45 berlabel PerCP, Annexin V berlabel FITC, dan Propidium Iodide. Pada kedua kelompok tersebut dicatat data karakteristik subyek dan dilakukan penghitungan jumlah apoptosis limfosit

Rerata jumlah apoptosis limfosit pada kelompok pasien hidup adalah 0,992% dengan simpang baku 0,44% dan rerata jumlah apoptosis limfosit pada kelompok pasien meninggal adalah 1,5853% dengan simpang baku 0,57%. Jumlah apoptosis limfosit pada kedua kelompok berbeda bermakna dengan nilai p 0,004. Ditentukan nilai cut-off jumlah apoptosis limfosit 0,97%untuk menentukan prognosis pasien sepsis, dengan AUC 0,791 (IK 95% 0,631 ? 0,951), sensitivitas 86,7%, dan spesifisitas 60%. Kurva Kapplan Meier berdasarkan nilai cut-off 0,97% menunjukkan gambar yang memenuhi asumsi proporsional hazard dengan rasio hazard 0,182 (IK 95% 0,041 - 0,814), p = 0,026. Kami menyimpulkan jumlah apoptosis limfosit pasien sepsis berat dapat digunakan untuk memprediksi pasien yang meninggal dilihat dari mortalitas 14 hari, dengan nilai AUC sedang. Cut-off jumlah apoptosis limfosit 0,97% dapat digunakan sebagai cut-off dalam tatalaksana pasien sepsis berat
ABSTRACT
Sepsis is a common illness in intensive care, almost 1/3 of patients admitted to the ICU were sepsis patients. There are plenty of researches to find a reliable marker of sepsis and the number of apoptotic lymphocytes began widely studied as a marker of sepsis. Apoptosis of lymphocytes occurred from the first 24 hours after the onset sepsis. There are currently no data on whether the number of apoptotic lymphocytes can be used as a prognostic marker of sepsis. The purpose of this study was to determine whether the number of apoptotic lymphocytes can be used as a prognostic marker in patients with severe sepsis

This was a prospective prognosis study, consisting of 30 severe sepsis patients grouped based on 14-day mortality, 15 patients are survivors and 15 patients are nonsurvivors. The diagnosis of sepsis is based on a modified definition of sepsis by the International Sepsis Definitions Conference 2001. The number of apoptotic lymphocytes was calculated using flowcytometry with PerCP-labeled anti-CD45 monoclonal antibody, FITC-labeled Annexin V, and Propidium Iodide. In both groups, characteristics of subjects were recorded and the number of apoptotic lymphocytes was calculated.

The mean of apoptotic lymphocytes in the survivor group is 0.992% with a standard deviation of 0.44%, and the mean of apoptotic lymphocytes in the nonsurvivor group is 1.5853% with a standard deviation of 0.57%. The difference between the two groups is significant with p = 0.004. This study yields an apoptotic lymphocytes cut-off value of 0.97% to determine prognosis of severe sepsis patients, with AUC of 0.791 (CI 95% from 0.631 to 0.951), 86.7% sensitivity and 60% specificity. Kapplan Meier curve based on the 0.97% cut-off demonstrates that hazard proportion is fulfilled with hazard ratio of 0.182 (95% CI 0.041 to 0.814) and p= 0.026. It is concluded that the number of apoptotic lymphocytes in severe sepsis patients can be used to predict nonsurvivors based on 14-day mortality, with moderate AUC. The apoptotic lymphocytes cut-off value of 0.97% can be used as a cut-off for severe sepsis patient management

Sampel yang digunakan adalah limfosit limpa mencit Balb/c jantan sebanyak 24 ekor yang dibagi ke dalam 4 kelompok yaitu kelompok kontrol tidak diimunisasi , kelompok 24 jam, 48 jam dan 72 jam. Limpa diambil berturut-turut setelah 0,24,48, dan 72 jam imunisasi. SDMT diperoleh dari darah limpa menggunakan larutan Ficoll 1.084, kemudian limfosit diisolasi dengan metode adheren. Ekspresi protein HIF-1?, HIF-2?, dan Nrf2 menggunakan metode ELISA; ekspresi relatif mRNA HIF-1?, HIF-2? diukur dengan metode qRT-PCR; dan aktivitas enzim GPx diukur dengan metode spektrofotometri. Protein HIF-1? meningkat secara signifikan pada 24 jam pertama setelah imunisasi, kemudian menurun setelah 48 jam dan 72 jam, ekspresi relatif mRNA HIF-1? meningkat setelah 48jam dan 72 jam. Hal ini disebabkan oleh protein HIF-1 distabilkan pada jam ke-24, setelah 48 jam dan 72 jam mRNA tidak ditranslasikan atau protein segera didegradasi. Protein HIF-2? meningkat secara signifikan setelah 72 jam imunisasi, sementara ekspresi relatif mRNA HIF-2? meningkat secara signifikan setelah 24 jam dan 72 jam setelah imunisasi. Hal ini menjelaskan bahwa protein HIF-2 bekerja pada hipoksia kronik. Protein Nrf2 mengalami peningkatan yang tidak signifikan setelah 48 jam. Aktivitas enzim GPx meningkat signifikan pada 24 jam pertama kemudian menurun setelahnya. Kemungkinan setelah 48 jam enzim GPx tidak bekerja sendiri dalam menetralkan radikal bebas, namun dibantu oleh enzim CAT yang juga diatur ekspesinya oleh Nrf2.
ABSTRACT
This research use experimental method, the aim is to explore the mice rsquo s spleen lymphocytes responses towards relative hypoxia and oxidative stress due to immunization. The immunization performed by injecting 2 sheep red blood cell intraperitoneally. The samples are spleen lymphocytes from 24 male Balb c mice, divided into 4 groups control, 24 hours, 48 hours, and 72 hours group. Spleen was isolated after 0 hour, 24 hours, 48 hours and 72 hours after immunization. PBMC obtained from spleen blood through Ficoll 1.084 separation, then lymphocytes were isolated by adherent method. HIF 1 , HIF 2 and Nrf2 protein expression were analyzed with ELISA method, mRNA expression were analyzed with qRT PCR method, and GPx enzyme activity were analyzed through spectrophotometry. HIF 1 protein elevated significantly 24 hours post immunization and decreased afterwards while HIF 1 mRNA increase significantly after 47 hours and 72 hours post immunization. This result is due to stabilized HIF 1 protein on 24 hours group that give rise to its concentration while its mRNA remain low, while after 48 hours and 72 hours the mRNA expression increase but not translated into protein or the protein sin quickly degraded. HIF 2 protein increased significantly 72 hours post immunizaation while mRNA expression elevated on 24 hours and 72 hours group. This result suit the theory that HIF 2 protein works on chronic hypoxia. Nrf2 protein increase insignificantly on 48 hours post immunization and GPx activity rise significantly after 24 hours immunization and decrease afterwards. This may due to enzyme CAT helps enzyme GPx in neutralize free radical, in which CAT is also regulated by Nrf2 protein.
