Abstract

In many patients presenting with chest pain symptoms at the emergency room, cardiac markers are measured not only to detect acutemyocardial infarction (AMI) but to exclude them too. Presently, the only biochemical markers used for diagnosis of MI are creatine kinasemyocardial band (CKMB) and troponin T (cTnT) as the markers of myocardial necrosis. Other biochemical markers have been sought tofind marker which can reflect the important, upstream processes in the pathophysiology of MI that therefore might give an earlier signalof ongoing MI. These markers are myeloperoxidase (MPO) and matrix metalloproteinase-9 (MMP-9) as markers of plaque destabilization.The aim of this study was to analyze the CKMB, MPO, MMP-9 activityies and troponin T level in MI. A cross sectional study had beendone at the Cardiovascular Centre Unit and Internal Ward of Dr. Wahidin Sudirohusodo Hospital during April up to August 2010 period.The laboratory tests were done at the Clinical Pathology Laboratory of Dr. Wahidin Sudirohusodo Hospital, Makassar and the Researchand Esoteric Unit of Prodia Clinical Laboratory, Jakarta. Ffifty-three patients with AMI had been examined. The results showed that themeans of CKMB, cTnT, MPO and MMP-9 were 52.4 U/L, 2.0 ng/mL, 217.9 ng/mL and 920.3 ng/mL, respectively. MMP-9 had positivelyvalue (69.8%) higher than cTnT (60.4%), MPO (58.5%) and CKMB (45.3%). Troponin T and MMP-9 were higher in patients with highCKMB. The higher level of CKMB will be the higher MPO, MMP-9 and cTnT. There were strong correlation between MPO and MMP-9, alsobetween CKMB and Troponin T. Troponin T and CKMB were lower in inferior wall infarction compared with anterolateral/anteroseptal wallinfarction. The most sensitive biochemical marker in patients with AMI is the MMP-9. The MMP-9 usage is suggested to assist the diagnosisof AMI. It is suggested a further study to establish the specificity of MMP-9 in all patients suffering with chest pain.

Abstract

The reference values of laboratory tests are affected by factors such as instruments and methods of tests, which are always beingdeveloped. For these reasons, each laboratory is recommended to determine their own reference values. To determine the reference valuesof complete blood count in healthy adult people, and compare them to the reference values which is taken from the references. A crosssectional study was conducted on 200 healthy adult people, aged 18-60 years, selected during blood donation. The eight haematologicalparameters were estimated using Sysmex Xt-1800i at Dr.Wahidin Sudirohusodo Hospital. The data were analyzed statistically by SPSS11.5 programs. The reference values of leukocyte, erythrocyte, haemoglobin, hematocrit, MCV, MCH, MCHC and platelet were: 4400 to10000 /µL; %:4.2–6.2 × 106/µL; &:3.8–5.5 × 106/µL; %:12.5–17.3 g/dL; &:11.8–15.4 g/dL; %:38.1–50.4 %; &:31.1–49.7 %; 80,1to 94,3 fL, 25,9–31,9 pg, 31,4–35,2 g/dL, and %:171.2–405.1 × 103/µL; &:191.8–441.5 × 103/µL, respectively. Significant differenceswere observed in the MCH and platelet values (p< 0,005). The values found in this study were similar to the reference value commonlyused in our laboratory, except for the MCH value which was lower and the platelet value which was higher..

Abstract

Chronically Kidney Disease (CKD) is the health problem of society worldwide, included Indonesia which its amount will increase.Clinical manifestation often following CKD is anaemia which will be severe with the increasing of serum creatinine values. To determinefrequent distribution of anaemia degree and assessing relationship between haemoglobin (Hb) and creatinine concentration in CKDpatients. Retrospective Descriptive Study in CKD patients with anaemia. In the period of May-September 2006, from 50 CKD patientsat the Department of Internal Medicine, Dr.Wahidin Sudirohusodo Hospital Makassar, 38 patients (76%) suffered severe anaemia(Hb < 8 g/dl). Mean value of Hb was 6,85 g/dl and serum creatinine concentration was 11.89 mg/dl. There was a significantrelationship between increasing of serum creatinine and decreasing of Hb (p = 0,013). Majority of CKD patients suffered from severeanaemia, there was relationship between increasing of serum creatinine and decreasing of Hb. To make routine blood tests and bloodsmears in CKD patients is needed, with large of samples to assess the relationship between Hb and serum creatinine.

Abstract

 Dengue Hemorrhagic Fever (DHF) is usually diagnosed based on the clinical symptoms and laboratory examinations of platelet index, including platelets count,: the Mean Platelet Volume (MPV), and the Platelet Distribution Width (PDW), but the most common use is the serological tests which can distinguish between the primary and secondary infection. The aim of this study was to know the three parameters in primary and secondary infections of the dengue patients during the hospitalization. This study was performed by a retrospective cohort study at the pediatric ward of Dr. Wahidin Sudirohusodo Hospital Makassar during the period of March−June 2010. Forty five samples have been examined, where 37.8% were men and 62.2% were women. Most DHF cases were at the age of 8−14 years (47%). The mean platelets count after the day five of their hospitalization in both primary and secondary infections showed a significant increase (p<0.05), with the mean of 124.3×103/μL and 109.7×103/μL respectively. The same result was obtained with the MPV (p<0.05). In contrast of the finding, the mean of PDW showed no significant increase (p>0.05). It can be concluded that platelet count and MPV can be used as the early markers for the improvement of DHF patients during their hospitalization, so that the patients can be discharge and the period of their hospitalization will become shorten.

Abstract

This research was motivated by the discovery of several problems faced by students, namely poor interest in learning, such as the level of activeness of students during the learning process and low interest of students in SKI learning. Students felt that in this learning there was no passion or interest, as indicated by students being less active in the learning process and student involvement in the SKI learning process also decreased. With these conditions, students quickly get bored and are not interested in participating in learning. As a result, difficulties arise that affect the learning objectives to be achieved. This study aims to determine the relationship between learning strategies and learning media with interest in learning Islamic Cultural History class VIII at MTsN 1 Bukittinggi. The type of research used in this research is quantitative, correlational. The population is all class VIII students with a total of 347 students spread across 11 classes. The sample in this research used the Probability Sampling technique using Simple Random Sampling, and the total research sample was 78 students. Data was collected through questionnaires, observation and documentation analyzed using normality tests, linearity tests, multiple correlation analysis and hypothesis testing. Based on the results of the research that has been done, the results show that there is a relationship between learning strategies on student interest in learning in the subject of Islamic Culture History class VIII at MTsN 1 Bukittinggi City and the relationship between learning media on student interest in learning in the subject of Islamic Culture History class VIII at MTsN 1 Bukittinggi City, as evidenced by the results of the Pearson Product Moment correlation test on the relationship between learning strategies and interest in learning with a Pearson correlation value of 0.382 and a significant value of 0.001 <0.05. While the Pearson correlation test results on the relationship between learning media and interest in learning are 0.236 with a significant value of 0.038 <0.05. Furthermore, the results of the Pearson correlation test on the relationship between learning strategies and media with learning interest are <0.05, which is certainly valid and related. Based on this value, it can be seen that the relationship between learning strategies to interest in learning is interconnected and the relationship between learning media to interest in learning is interconnected, so Ha is accepted.
