Hypertension as a Determining Factor in the Rupture of Intracranial Aneurysms, Diagnosed by 64-MDCT Angiography

Background: To determine a correlation between risk factors and the rupture of intracranial aneurysms. Methods: A cross-sectional study of 29 patients with a saccular intracranial aneurysm was obtained using consecutive sampling and examination of 64-MDCT angiography. Bivariate statistical analysis using Fisher's exact test was arranged using cross-tabulation to determine the correlation between each risk factor of age, sex, hypertension, and smoking with the occurrence of ruptured intracranial aneurysms. Results: The highest incidence of ruptured intracranial aneurysms were in patients aged <60 years (70%), male (75%), experienced hypertension (85%), and were smokers (85.7%). Only the risk factor of hypertension had a correlation with the occurrence of a ruptured intracranial aneurysm (p < 0.05). The prevalence ratio of age and sex were 1.0 and 0.9, whereas hypertension and smoking were 2.6 and 1.3. Conclusions: The risk factor of hypertension leading to a ruptured intracranial aneurysm was 2.6 times higher than non-hypertensive patients, and as such hypertension is a risk factor associated with the occurrence of ruptured intracranial aneurysm

Metode PCR dapat digunakan untuk membantu pemeriksaan secara mikroskopis dalam penentuan spesies mikrofilaria. Hasil sekuensing DNA mikrofilaria menunjukkan adanya spesies B.timori yang tidak ditemukan pada pemeriksaan secara mikroskopis.Kata Kunci: filariasis, Brugia malayi, Brugia timori, PCR AbstractFilariasis is a chronic infectious disease caused by filarial worms. In Indonesia there are three species of filarial worm that is: Wuchereria bancrofti, Brugia malayi and Brugia timori. The main species found inSumatra is B.malayi. Filariasis transmission can occurred by mosquitoes bite of the patient containing microfilariae. Chronic sufferers can become a source of transmitting filariasis if it still contains filarialworms in his blood. Microscopic examination results in chronic sufferers often do not find the microfilariae, so that the necessary examination by polymerase chain reaction (PCR). Therefore conducted research aimed at determining the level of endemicity and status of chronic filariasis patients and its microfilariae species using microscopically and PCR. The total population of the positive results of blood tests as many as 9 people (Mf rate 0.31-1,75%). PCR on 25 samples get 8 positive samples containing DNA filarial worms. PCR methods can be used to assist in the determination by microscopic examination microfilariae species. DNA sequencing results indicate the presence of microfilariae B.timori species are not found on microscopic examination.Keywords : filariasis, Brugia malayi, Brugia timori, PC

Refleksi Kritis Atas Metode Berfilsafat Damardjati Supadjar

The strength-ness of Damardjati Supadjar philosophical thought method is: unique, operational, and testified. Unique consist in that his thought are special and different from the other philosophers. The meaning of operational is applicable by one who ready to experience it. Testable has a meaning that someone who doing with the method, necessarily acknowledge that the method effective enough to developing the new consciousness.

Hypothesis testing shows variable X1 (number of independent commisioner members), variable X2 (Institutional Ownership), and variable X3 (number of audit committee) had no significant effect on firm value. However, variable X4 (number of board members) and variable X5 (return on assets) show significant effect on firm value. Simultaneous testing demonstrated a significant effect from the five independent variables on firm value. The analysis indicates that applied good corporate governance will significantly affect company performance and hence will be transferred to company

Kebijakan Manajemen Leverage Dan Pengaruhnya Terhadap Kenaikan Profitabilitas Perusahaan Studi Kasus Pada Perusahaan PT Charoen Pokphan Indonesia, Tbk

The use of leverage in running a company aims to increase its profit. Leverage can be differentiated into two; operating and financial leverage. In the daily operations, the company uses both leverages simultaneously. In other words, the company uses a combined leverage. The aim is to increase the shareholders net income or earnings per share because of the increase in the sales resulted from the use of leverage. This study aims to determine the extent of the influence of using combined leverage to increase return on equity and earnings per share. The study was conducted using case study method. The poultry feed company, PT Charoen Pokphan Indonesia, Tbk (CPIN), became the object of the research. The results show that CPIN used a fairly large leverage in its operation during 2005 to 2008. However, the company management took another policy which was to reduce the use of operational leverage in 2009. The result indicates that the use of leverage did not bring significant impact on improving ROE and EPS. This happened because the cost of the company's operations outside the fixed costs as a result of using leverage was very large. Therefore, CIPN should control its operational costs in the future
