Background: Zinc is the main constituent element of Superoxide Dismutase (SOD) which acts to protect cells from inflammation and the toxic effects of Reactive Oxygen Species (ROS). High ROS production induces fat peroxidation, and forms malondialdehyde (MDA) which causes oxidative stress.Objectives: This study aimed to analyze the difference of zinc and malondialdehyde levels among Multi Drug Resistant Tuberculosis and sensitive Tuberculosis.Methods: Crossectional study with 55 subjects consisted of 32 MDR-TB subjects and 23 subjects TB sensitive. Selection of subjects using consecutive sampling. Zinc and MDA serum was obtained from venous blood. Zinc and MDA concentration were assessed by quantitative colometric and Thiobarbituric Acid Reactive Substances (TBARS) respectively. Data were analized statistic by independent t-test and Mann Whitney test.Results: Zinc level of MDR-TB and TB sensitive were 74.85 (64 - 97) μg/dl and 73.03 (63 - 97) μg/dl respectively, while MDA of MDR-TB and sensitive TB were 2.262±1.055 nmol/mL and 2.66±0.992 nmol/mL. There was no significantly different in zinc level between MDR-TB and sensitive TB (p=1.000). Furthermore, there was not significantly different of MDA level between MDR-TB and sensitive Tuberculosis (p=0,147).Conclusion: There are no differences in zinc and MDA levels in patient between MDR-TB and sensitive TB.

Mammography is a radiographic examination to detect breast cancer earlier. However, the usage of radiation with low kVp can cause high dose and this becomes the reason why monitoring the dosage during the mammography process is an important thing to do. One of the techniques to monitor the radiation level is done based on the Entrance Skin Exposure (ESE) value. This research was aimed to determine the ESE value using molybdenum (Mo) and rhodium (Rh) as the filter at Mammomat 1000 mammographics system.The research was started by measuring the consistency of the X-ray tube voltage (kVp ). After that, the ESE value at the target/filter Mo/Mo and Mo/Rh was measured using a Barracuda Multi Purpose Detector (MPD). The tube voltage during the research was 26, 28, and 30 kVp with fixed electrical current-time 100 mAs. The result shows that ESE value resulted at the target/filter Mo/Mo and Mo/Rh is tolerable, except at tube voltage 30 kVp with target/filter Mo/Mo. The comparison of ESE value shows that Mo/Rh has lower ESE value than Mo/Mo. Â Keywords: Entrance Skin Exposure (ESE), mammography, Barracuda Multi Purpose Detector (MPD) Â Â Pemeriksaan mammografi merupakan tindakan efektif dalam mendeteksi adanya kanker payudara sejak dini. Namun demikian, penggunaan teknik radiasi dengan kVp rendah pada mammografi dapat menyebabkan dosis tinggi. Oleh karena itu, pemantauan dosis pada pemeriksaan mammografi sangat penting dilakukan. Salah satu teknik pemantauan dosis radiasi dapat dilakukan dengan nilai Entrance Skin Exposure (ESE). Penelitian ini bertujuan untuk menentukan nilai ESE dengan filter molybdenum (Mo) dan rhodium (Rh) pada pesawat mammografi Mammomat 1000. Penelitian diawali dengan pengukuran konsistensi keluaran tegangan tabung sinar-X (kVp output). Selanjutnya dilakukan pengukuran nilai ESE pada target/filter Mo/Mo dan Mo/Rh dengan menggunakan Multi Purpose Detector (MPD) merek Barracuda. Tegangan tabung yang digunakan dalam penelitian yaitu 26, 28 dan 30 kVp dengan arus-waktu tabung tetap yaitu 100 mAs. Hasil penelitian menunjukan bahwa nilai ESE yang dihasilkan pada target/filter Mo/Mo dan Mo/Rh masih berada dalam batas toleransi yang direkomendasikan, kecuali pada pada tegangan tabung 30 kVp untuk Mo/Mo. Hasil perbandingan nilai ESE menunjukan bahwa Mo/Rh memiliki nilai ESE yang lebih rendah dibandingkan dengan Mo/Mo. Â Kata kunci : Entrance Skin Exposure (ESE), mammografi, Multi Purpose Detector (MPD) Barracuda.
