The purpose of this study is to know whether there are differences between hematology profile and morphology of erythrocyles of blood specimens which are prepared with excessive Na2EDTA anticoagulant in different concentration. This study was conducted in Faculty of Medicine Gadjah Mada University. The criteria of subject were male, age from 18 until 22 years old and healthy, ascertained from history taking and vital sign examination. Blood samples from 33 subjects were taken using vein puncture. Two millimeters blood was divided into 4 Na2EDTA-containing tube's. Before that, one drop of blood without Na2EDTA anticoagulant was used for making control blood film right after vein puncture. Each tubes contained different concentration of anticoagulant. The first tube contained Na2EDTA in standard concentration 2 mg/dl; the remaining tubes contained consecutively, 4 mg/dl, 6 mg/dl, and 8 mg/dl. Those samples were immediately examined using SYSMEX SE-9500 automatic analyzer for measuring erythrocytes hematological profile and were stained with Wright staining far morphological examination. These procedures were done before 20 minutes of vein puncture. There were significant decrease ofRBC count, HGB, HCT, and MCHC and also significant increase of MCV and RDW between different concentrations of excessive Na2EDTA anticoagulant. MCH did not have significant result. Morphological examination showed significant morphological changes in the form of echinocytes and appearance of ghost cells in the sample treated with excessive Na2EDTA anticoagulant concentration. In conclusion, there are differences in hematological profile and morphology of erythrocytes among blood specimen which are prepared with excessive Na2EDTA anticoagulant in different concentration, except for MCH. Excessive Na2EDTA anticoagulant concentration will affect the blood specimen for peripheral blood examination of erythrocytes by interfering morphology and some of hematological parameters.

"Pemeriksaan hematologi banyak dilakukan dengan menggunakan alat hitung sel darah otomatis yang mencakup parameter pemeriksaan seperti jumlah leukosit, jumlah eritrosit, kadar hemoglobin, hematokrit, volume eritrosit rata-rata (VER), hemoglobin eritrosit rata-rata (HER), konsentrasi hemoglobin eritrosit rata-rata (KHER), red distribution width (RDW), jumlah trombosit, mean platelet volume (MPV) dan platelet distribution width (PDW). Untuk pemeriksaan tersebut perlu diperhatikan beberapa hal, seperti persiapan penderita, cara pengambilan bahan dan pengiriman bahan bila bahan tersebut dirujuk serta antikoagulan yang dipakai. Kesalahan yang terjadi pada hal-hal tersebut di atas dapat mempengaruhi hasil pemeriksaan. Untuk pemeriksaan hematologi tersebut, biasanya dipakai darah vena yang dicampur dengan antikoagulan, agar bahan darah tersebut tidak menggumpal. Antikoagulan yang sering dipakai antara lain garam EDTA seperti tripotassium EDTA (K3EDTA). Beberapa kepustakaan menyebutkan bahwa penggunaan garam EDTA yang berbeda dan atau konsentrasinya yang berbeda dapat menyebabkan perbedaan kuantitas maupun kualitas hasil pemeriksaan. Lamanya penundaan pemeriksaan juga dapat memberikan hasil yang berbeda untuk parameter tertentu. Saat ini banyak penelitian yang memerlukan pemeriksaan hematologi dilakukan di lapangan sehingga ada kecenderungan untuk melakukan penundaan pemeriksaan hematologi yang dibutuhkan. Sehubungan dengan hal tersebut di atas, ingin diketahui batas waktu lamanya penyimpanan darah dengan antikoagulan K3EDTA dalam tabung vacuette pada suhu kamar dan lemari es sebelum terjadinya perubahan kuantitas maupun kualitas yang minimal pada beberapa pemeriksaan hematologi serta pengaruh perbedaan suhu penyimpanan bahan tersebut. BAHAN, ALAT DAN REAGENSIA Behan penelitian : Behan penelitian berasal dari 27 orang yang memerlukan pemeriksaan hematologi di laboratorium Patologi Klinik Rumah Sakit Umum Pusat Nasional Dr. Cipto Mangunkusumo Jakarta (RSUPN CM) antara tanggal 1 Maret 1998 sampai dengan tanggal 10 April. 1998.

"Perubahan iklim telah menjadi isu global dan diyakini disebabkan oleh aktivitas manusia yang berhubungan dengan produksi gas rumah kaca (greenhouse gases), salah satunya adalah karbon dioksida. Peningkatan konsentrasi karbon dioksida memberikan efek tidak hanya pada lingkungan sekitar, tetapi juga sistem tubuh. Kejadian ini dihubungkan dengan kemunculan berbagai penyakit akibat kondisi hiperkapnia yang menimbulkan efek merusak pada sel dan jaringan tubuh, termasuk sistem imun. PBMC merupakan salah satu komponen penting sistem imun yang berperan sebagai lini pertama tubuh dalam menghadapi berbagai perubahan lingkungan, termasuk peningkatan karbon dioksida. Tingkat karbon dioksida tinggi dapat menimbulkan perubahan pada ekspresi berbagai gen yang berperan dalam meregulasi respon seluler terhadap perubahan yang ada. Salah satu gen yang dimaksud adalah HIF-1α. HIF-1α merupakan salah satu protein faktor transkripsi utama dalam tubuh yang berfungsi untuk mengatur berbagai macam mekanisme seluler terhadap keadaan hipoksia. Oleh karena itu, penelitian ini ditujukan untuk mempelajari lebih lanjut mengenai efek peningkatan karbon dioksida terhadap ekspresi HIF-1α pada PBMC. PBMC dipisahkan teknik sentrifugasi, kemudian dikultur dan disimpan dalam empat keadaan yang berbeda (5% CO2 24 jam, 15% CO2 24 jam, 5% CO2 48 jam, dan 15% CO2 48 jam). Kemudian, RNA diisolasi dan dicek dengan teknik reverse transcriptase real-time PCR. Hasil dari kelompok sampel 24 jam menunjukkan perbedaan yang signifikan dalam hal tingkat ekspresinya. Sedangkan pada kelompok sampel 48 jam, hasil menunjukkan perbedaan ekspresi yang tidak signifikan. Dari penelitian ini, dapat disimpulkan bahwa adanya penurunan ekspresi HIF-1α ketika peningkatan karbon dioksida terjadi. Akan tetapi, ekspresi HIF-1α menunjukkan sedikit peningkatan setelah perlakuan selama 48 jam.

Climate change has become a major global issue since the past few years, and it is caused by human activities related to the emissions of greenhouse gases, one of which is carbon dioxide. Elevated level of carbon dioxide has been found to affect not only our environment, but also our body system. It is linked to many adverse clinical outcomes due to the hypercapnic condition towards many cells and tissues, including our immune system. PBMCs, a major components of immune system, are the first-line defence against various environmental changes, including increased carbon dioxide level. High carbon dioxide are thought to cause alterations of numerous genes expression, including HIF-1α, resulting in defective cellular response. HIF-1α is one of the most important transcription factor proteins for numerous cellular mechanisms related to hypoxia. Therefore, this research is aimed to study about the effects of increased carbon dioxide towards HIF-1α expression in PBMCs. PBMCs are separated from the blood by centrifugation, cultured, and treated under four different conditions (5% CO2 24 hours, 15% CO2 24 hours, 5% CO2 48 hours, and 15% CO2 48 hours. The RNA are then isolated and tested by reverse transcriptase real-time PCR. The result of 24-hour group showed a significant difference in the mRNA expression, unlike the difference in expression showed by the result of 48-hour group. In conclusion, the result showed that the expression of HIF-1α was decreased upon treated with increased carbon dioxide level. The expression, however, slightly increase after 48-hour period."

Decreased total body iron will cause iron deficiency, which could end up to iron deficiency anemia. Currently, immature reticulocyte fraction (IRF) was introduced as a parameter to show young reticulocyte fraction in the circulation, as a useful tool to evaluate erythropoiesis activity. The aim of this study was to investigate the correlation between IRF with serum iron and ferritin concentrations, and with transferin saturation, and between serum ferritin with hepcidin concentration. A cross sectional study was conducted in Pramuka island involving 77 post-menarchal adolescent school girls, who had received twice weekly iron supplementation for 12 weeks. Serum concentrations of iron, ferritin, and hepsidin, haemoglobin concentration, transferin saturation, absolute reticulocyte count, and IRF were determined. There were significance correlations between IRF with serum iron and ferritin, concentrations, and with transferin saturation (p<0.0001, r = - 0.443; p<0.0001, r = -0.439 ; and p = <0.0001, r = -0.423, respectively), and between serum hepsidin and ferritin concentrations (p<0.001, r = 0.371). It can be concluded that IRF had significant correlation with iron status."

"Akurasi pemeriksaan profil lekosit dipengaruhi beberapa faktor preanalitik diantaranya konsentrasi antiokoagulan. Antikoagulan yang paling sering dipakai pada pemeriksaan darah rutin adalah EDTA. Ketidaksesuaian perbandingan konsentrasi EDTA dengan bahan darah berefek terhadap hasil pemeriksaan darah tepi diantaranya parameter lekosit. Penelitian ini bertujuan untuk mengetahui apakah terdapat perbedaan antara hasil pemeriksaan profil lekosit pada bahan darah dengan berbagai konsentrasi antikoagulan Na2EDTA yang berbeda. Penelitian ini merupakan penelitian potong lintang. Bahan penelitian berupa 33 sampel darah vena mahasiswa Fakultas Kedokteran UGM Yogyakarta. Dua mL darah dibagi ke dalam 4 tabung Na2EDTA.

Sebelumnya dibuat sediaan hapus langsung dari setetes darah tanpa antikoagulan (sebagai kontrol). Darah dalam keempat tabung tersebut segera dilakukan pembuatan sediaan hapus dan diperiksa profil hematologi lekositnya menggunakan SYSMEX SE-9500 automatic analyzer. Terdapat perbedaan yang bermakna dari hitung lekosit, hitung jenis lekosit absolut dan prosentase monosit pada konsentrasi Na2EDTA yang berlebihan. Prosentase netrofil relatif meningkat dan terdapat perbedaan yang bermakna. Prosentase limfosit, eosinofil dan basofil tidak berbeda secara bermakna. Pemeriksaan morfologi lekosit menunjukkan perubahan yang bermakna berupa tepi sitoplasma yang irreguler, vakuolisasi, dan lobus nukleus yang irreguler akibat pengaruh konsentrasi Na2EDTA yang belebihan. Disimpulkan bahwa penggunaan konsentrasi Na2EDTA yang berlebihan pada preparasi spesimen darah menyebabkan perubahan profil lekosit sesuai peningkatan konsentrasinya. Konsentrasi standar tidak mempengaruhi hitung lekosit dan hitung jenis lekosit serta morfologinya, kecuali berpengaruh terhadap tepi sitoplasma yang irreguler dan lobus nukleus yang irreguler.

Accuracy of leukocytes profile assessment is influenced by several pre analytical factors, among others, the anticoagulant concentration. EDTA is one of the most frequently used anticoagulant in peripheral blood examination. Several references stated that inappropriate concentration of EDTA anticoagulant in blood sample may affect the result of leukocytes profile in peripheral blood examination. The aim of this study was to evaluate whether there are differences among leukocytes profile in peripheral blood examination specimens, which were prepared with excessive Na2EDTA anticoagulant in different concentration. This study was conducted in Faculty of Medicine, Gadjah Mada University. Blood samples from 30 subjects were taken using vein puncture. Two millimeters blood was divided into 4 Na2EDTA-containing tubes. Before that, one drop of blood without Na2EDTA anticoagulant was used to make blood film right after vein puncture, as control. Each tubes contained different concentration of anticoagulant. The first tube contained Na2EDTA in standard concentration 2 mg/ml; the remaining tubes contained 4 mg/ml, 6 mg/ml, and 8 mg/ml respectively. These samples were immediately examined using SYSMEX SE-9500 automatic cell counter to measure the total and differential leukocytes count; and were stained with Wright staining for morphological examination under the microscope. These procedures were done before 20 minutes of vein puncture. There were significant decrement of total leukocytes count, absolute differential leukocytes count and monocyte percentage following excessive Na2EDTA administration. Neutrophil percentage was found to be relatively increased and the difference was significant. Lymphocyte, eosinophil and basophil percentages were not significantly different. Morphological examination showed significant increment in irregular cytoplasm margin, vacoulation and irregular nuclei lobes following excessive Na2EDTA administration. It is concluded that excessive concentration of Na2EDTA used in blood specimen preparation, will lead to changes in leukocytes profile as the concentration increased. Standard Na2EDTA anticoagulant concentration did not alter any leukocytes count and morphology, except for irregular cytoplasm margin and irregular nuclei lobes. (Med J Indones 2007; 16:168-75)"

Background: Retinoblastoma is the most common intraocular malignancy and is also one of the most common solid tumors in children. In developed countries where treatment is good and early detection is available, the prognosis and survival is good. Unfortunately, in developing countries including Indonesia diagnosis is still often delayed and survival is still low. Complete blood count as a relatively accessible and affordable test has been studied to provide valuable prognostic information and help in assessing the survival in various types of cancers. However, such studies is still very limited in retinoblastoma cases.

Objectives: This study aims to identify the relation between peripheral blood profile on first presentation and survival in retinoblastoma.

Methods: This study uses retrospective cross sectional study design by collecting medical records of retinoblastoma patients diagnosed from January 2011 to December 2013 in Cipto Mangunkusumo Children and Maternal Hospital 'Kiara'. The demography and clinical profile of patients is collected and outcome is categorized into event dead and censored not dead. Survival analysis is done using Kaplan Meier with SPSS.

Results: Survival analysis using Kaplan Meier method and log rank test shows no significant difference in survival between patients, either according to hemoglobin status p 0,219 , leukocyte status p 0,903 , and thrombocyte status p 0,649 before receiving systemic therapy. Nevertheless, there seem to be a trend of lower mean survival in group with abnormal Hb and leukocyte, although such relation is not seen in thrombocyte.Conclusion Although there is no significant relation, there seem to be a trend in which patients with worse peripheral blood profile has worse survival."
