Pengaruh pemberian ekstrak centella asiatica terhadap struktur histopatologis hipokampus dan kemampuan kognitif pada tikus sprague dawley tua = Administration of centella asiatica extract on hippocampal histopathological structure and cognitive ability in old sprague-dawley rats
"ABSTRAK
Latar Belakang : PBB menyatakan bahwa Indonesia memiliki kecenderungan peningkatan harapan hidup sebesar 71,7 di kisaran tahun 2010-2015 yang diperkirakan akan meningkat menjadi 77,6 pada 2045-2050. Hal ini dapat meningkatkan beban penanganan penyakit tidak menular. Oleh karena itu, penelitian dilakukan dengan tujuan mencari ekstrak tanaman herbal yang dapat memperlambat proses penuaan pada tikus tua dengan meninjau parameter histopatologis. Ekstrak Centella asiatica (CA) diketahui berpotensi dalam mengurangi tingkat penuaan di cerebrum. Metode : Penelitian dilakukan menggunakan 4 kelompok : kontrol negatif, perlakuan (CA 300 mg/kgBB), kontrol positif (Vitamin E 6 IU) dan tikus muda yang diberi perlakuan selama 28 hari. Setiap kelompok memiliki jumlah sampel minimal 4. Setelah 28 hari, tikus diterminasi dan diambil sediaan otaknya untuk dibuat preparat histopatologis pada bagian hipokampus. Sediaan kemudian diidentifikasi 4 variabel yaitu densitas sel normal, densitas sel abnormal, densitas sel piramidal, densitas sel piknotik dan densitas sel total pada 2 bagian hipokampus yaitu girus dentatus dan CA3. Analisis dilakukan secara komparatif pada 2 jenis sampel tersebut. Hasil : Pada akhir perlakuan, kelompok kontrol positif tidak dianalisis karena tidak memenuhi jumlah sampel minimal. Pada sampel girus dentatus, hasil analisis one-way anova menunjukkan hasil bermakna pada variabel densitas sel normal dan densitas sel abnormal, tetapi analisis post-hoc Bonferroni menunjukkan hasil yang tidak bermakna pada kelompok CA dibandingkan dengan kontrol negatif dan tikus muda. Sedangkan sediaan sampel CA3 tidak memiliki hasil yang bermakna pada analisis komparatif kategorik. Diskusi : CA diketahui memiliki efek antioksidan yang baik namun memerlukan durasi perlakuan yang lebih panjang untuk mendapat efek anti-penuaan.
ABSTRACT
Background: United Nations states that Indonesia has tendency to increase life expectancy in 2010-2015 by 71.7, and expected to increase to 77.6 in 2045-2050. This can increase the burden of handling non-communicable diseases. Therefore, research was conducted aiming to find herbal extracts that can slow down aging process in old mice by reviewing histopathological parameters. Centella asiatica (CA) is known to be potential in reducing the rate of aging in cerebrum. Method: The study was conducted using 4 groups: negative control, treatment (CA 300 mg/kgBW), positive control (Vitamine E 6 IU) and young mice days with each minimum sample size of 4. After 28 days of treatment, rats were terminated and brain preparations were taken to make histopathological preparations in 2 parts of hippocampus section : dentate gyrus and CA3. The preparations then identified 4 variables : normal cell density, abnormal cell density, pyramidal cell density, picnotic cell density and total cell density. The analysis was carried out comparatively. Results: At the end of the treatment, the positive control group was not analyzed due to low number of samples. In dentate gyrus, the results of One-way Anova analysis showed significant results on normal cell density and abnormal cell density variables, but Bonferroni's post-hoc analysis showed no significant results in the CA group compared to negative controls and young mice. CA3 preparations did not have significant results in categorical comparative analysis. Discussion: CA is known to have good antioxidant effects but requires a longer duration of treatment to show anti-aging effect."

Gambaran klinis radiologis histopatologis dan faktor prognostik tumor otak pada anak = Clinical radiology histopathology features and prognostic factor of child brain tumor
"[ABSTRAK
Tumor otak (TO) merupakan penyebab kematian kedua dari
semua kanker yang terjadi pada anak. TO memiliki gambaran klinis, radiologis
dan histopatologis yang sangat bervariasi karena proses pengembangan sel-sel
jaringan otak masih berlanjut sampai usia 3 tahun. Data penelitian mengenai TO
pada anak masih sedikit.
Tujuan: Untuk mengetahui gambaran klinis, radiologis, histopatologis dan faktor
prognostik TO di Departemen Ilmu Kesehatan Anak FKUI/ RS. Dr.
Ciptomangunkusumo Jakarta periode tahun 2010 - 2015.
Metode Penelitian: Kohort retrospektif dilakukan pada semua anak dengan TO
primer yang berobat/dirawat di Departemen Ilmu Kesehahatan Anak FKUI/RS
Dr. Ciptomangunkusumo Jakarta.
Hasil: Didapatkan 88 pasien TO primer, terdiri dari 16 pasien berusia kurang dari
3 tahun dan 72 pasien berusia lebih dari 3 tahun, laki-laki 53% dan perempuan
47%. Anak usia kurang dari 3 tahun mengalami gejala sakit kepala (63%) dan
kejang (56%), berdasarkan radiologis letak TO yang terbanyak adalah di cerebral
ventrikel (25%) dan cerebellum (24%), berdasarkan histopatologis jenis TO yang
terbanyak adalah Astrositoma (31%) dan Medulloblastoma (25%). Anak usia
lebih dari 3 tahun mengalami gejala sakit kepala (81%) dan gangguan penglihatan
(65%), berdasarkan radiologis letak TO yang terbanyak adalah di cerebellum
(24%) dan suprasellar (10 %), berdasarkan histopatologis jenis TO yang
terbanyak adalah Medulloblastoma (21%), Astrositoma (18%) dan Glioma (17%).

Daya hambat ekstrak etanol tubastraea coccinea terhadap pertumbuhan lini sel kanker payudara MCF-7 = Inhibition effect of ethanol extract of tubastraea coccinea on breast cancer cell line MCF-7 growth
"Latar belakang: Kanker payudara adalah kanker yang paling banyak diderita wanita. Terbatasnya akses kemoterapi serta efek sampingnya yang signifikan, mendorong terus ditemukannya obat baru. Penelitian ini mengidentifikasi kandungan metabolit sekunder dari Orange cup coral (Tubastraea coccinea) dan menilai potensi anti kankernya melalui daya hambatnya terhadap pertumbuhan lini sel kanker payudara MCF-7. Metode: Identifikasi metabolit yang terkandung pada ekstrak etanol, etil asetat dan n- heksana Tubastraea coccinea yang diperoleh dari perairan laut pulau Kalimantan dilakukan dengan menggunakan Gas Chromatography Mass Spectrometry (GCMS). Uji daya hambat dari ketiga ekstrak T. coccinea terhadap pertumbuhan sel kanker payudara MCF-7 dilakukan dengan metoda MTT pada berbagai variasi konsentrasi (3,125 μg/mL- 200 μg/mL), hasil pengujian dibandingkan dengan doxorubicin sebagai kontrol positif. Hasil: Hasil GCMS menunjukkan adanya kandungan 21 metabolit sekunder dalam ekstrak ethanol T. coccinea dengan persentase tertinggi adalah senyawa 1,2- Benzendicarboxylic acid (13.89 %). Ekstrak etil asetat T. coccinea mengandung 23 metabolit dengan konsentrasi tertinggi adalah senyawa 1,2-Benzenedicarboxylic acid (18.3 %). Ekstrak n-heksana T. coccinea memiliki 28 metabolit, senyawa Cholest-5-en- 3-ol dengan persentase tertinggi (9,06 %). Benzenedicarboxylic acid merupakan metabolit yang teridentifikasi pada ketiga ekstrak. Daya hambat ketiga ekstrak terhadap pertumbuhan sel kanker payudara MCF-7 meningkat sesuai dengan peningkatan konsentrasi. Nilai IC50 dari ekstrak etanol, etil asetat dan n-heksana masing-masing adalah 12,08 μg/mL, 18,02 μg/mL, 30,66 μg/mL. Nilai IC50 untuk doxorubicin adalah 5,99E-4 μg/mL, lebih rendah secara sangat signifikan dibanding ketiga ekstrak T. coccinea (p<0.01).
Introduction: Breast cancer is the most prominent cancer affects women in the world. This research is aimed to explore the potency of Orange cup coral (Tubastraea coccinea) as a new nature derived cancer drug, through the identification of secondary metabolites from its extract, and explore its potency in inhibiting breast cancer cell line MCF-7 growth. Method: Identification and analysis of metabolites from ethanol, acetic ethyl, and n- hexane extracts of Tubastraea coccinea, obtained from Kalimantan island, was done using Gas Chromatography Mass Spectrometry (GCMS). MTT assay using various concentration (3,125 μg/mL-200 μg/mL) was done to analyse the cytotoxicity of all the extracts to MCF-7 cell line compare to doxorubicin. Result: Ethanol extract of Tubastraea coccinea was identified to contain 21 metabolites, with the highest concentration was 1,2-Benzendicarboxylic acid (13.89 %). 23 metabolites was identified from acetic ethyl extract, with 1,2-Benzenedicarboxylic acid, mono (2-ethylhexyl) ester as the highest concentration (18.3 %), whereas from n-hexane extracts was found to have 28 metabolites, and Cholest-5-en-3-ol was the most prominent (9.06 %). Benzenedicarboxylic acid is identified in all extracts. MTT assay showed that the cytotoxicity of all extracts is concentration dependent, with IC50 12.08 μg/mL, 18.02 μg/mL, 30.66 μg/mL, for extracts of ethanol, acetic ethyl and n-hexane respectively. Compared to all the extracts of T. coccinea, doxorubicin showed significantly stronger effect in the inhibition of growth of MCF-7 cell line (p<0.01) , with IC50 5.99E-4 μg/mL. Conclusion: Extracts of Tubastraea coccinea contain metabolites that give it potency to be used as breast cancer chemotherapy."

Kesesuaian antara gambaran ileoskopi dengan gambaran histopatologis ileum terminal pada pasien diare kronik kolonoskopi normal = Correlation between terminal ileum ileoscopy and histopathology image in patients with chronic diarrhea and normal colonoscopy
"ABSTRACT
Latar belakang: Selama ini pemeriksaan ileum kurang mendapatkan perhatian, padahal seringkali kelainan-kelainan gastrointestinal bawah berasal dari ileum dengan kolonoskopi normal. Oleh karena itu penelitian ini membahas tentang kesesuaian antara hasil pemeriksaan ileoskopi ileum terminal dengan hasil histopatologinya.
Metode: Metode yang digunakan adalah studi potong lintang dan uji diagnostik antara kedua pemeriksaan tersebut, dengan pemeriksaan histopatologi sebagai standar baku emas.
Hasil: Hasil penelitian memberikan kesesuaian antara kedua pemeriksaan tersebut sebesar 93,33 %. nilai sensitivitas pemeriksaan ileoskopi dibandingkan dengan histopatologi sebagai standar baku emas sebesar 94 %, spesifisitas 90 %, nilai prediksi positif 97,9 %, dan nilai prediksi negatif sebesar 75 %.
Kesimpulan: Dapat disimpulkan bahwa pemeriksaan ileoskopi pada pasien dengan diare kronik dan kolonoskopi normal memberikan hasil yang serupa dengan pemeriksaan histopatologinya.
ABSTRACT
