Judul: Nilai Referensi Motion Mode (M-Mode)  Echocardiography  Normal Pada Anjing Lokal  (Canis Lupus Familiaris)
Abstrak: Studi ini bertujuan untuk mengetahui dimensi intrakardiak, ketebalan dinding dan penghitungan yang diturunkan dari pengukuran M-mode echocardiography pada jantung anjing kampung normal dan membandingkannya dengan temuan literatur. Metode dilakukan secara langsung dengan dilakukan pemeriksaan echocardiography terhadap anjing. Dimensi jantung serta pengukuran M-mode lainnya dapat digunakan sebagai panduan dalam menentukan kerja jantung, menentukan diagnosa dan juga prognosa suatu penyakit. Meskipun pengukuran M-mode echocardiography ini diketahui sangat berguna, namun penelitian yang dilakukan dalam echocardiography anjing kampung masih sangat kurang. Sehingga perlu dilakukan penelitian untuk mengetahui keadaan normal organ kardiovaskular anjing kampung. Adapun hasil penelitian ini dapat dijadikan sebagai bahan acuan perbandingan pemeriksaan dan diagnosa penyakit jantung, serta dapat berguna sebagai studi untuk mengetahui keadaan normal organ kardiovaskular pada anjing kampung.

Judul: Karakteristik Aliran Darah Katup Atrio-Ventrikular Dinilai dengan Pulsed wave Doppler Echocardiography di Anjing Kampung Normal (Canis lupus familiaris).
Abstrak: The purpose of this study is to determine blood flow characteristics at the atrio-ventricular valve i.e. mitral and tricuspid valves in normal mongrel Indonesian dog using transthoracic pulsed wave Doppler (PWD) echocardiography. The study was conducted in eight adult dogs consisting of three males and five females with an average age of 3.5 years, and average weight 12 kg. Transthoracic PWD echocardiography examination were performed on dogs in a conscious state/unsedated and the animal's position in right lateral recumbency. The instrument used is an ultrasound device (Sonoscape SSI-1000) and convex type transducer with small footprint scanner of 3.7-5.0 MHz frequency. Seven parameters of PWD measured were heart rate/HR, velocity annulus/Va, velocity ejection/Ve, velocity time integral/VTI, mean pressure gradient/MPG, pulsatility index/PI, and ratio systole-diastole or S/D. Based on the measurement of seven parameters in both atrio-ventricular valves showed that in general the blood flow characteristics values of the mitral valve were higher than tricuspid valves (P> 0.05). While the female dogs have a higher value when compared with male dog (P>0.05).

Judul: Sintesis Krisin dari Floroglusinol
Abstrak: Flavone is a class of flavonoid, widely distributed in vascular plants. Flavones containing hydroxyl groups at 5 and 7 position are quite important regarding their biological activities and their abiquity in nature. Flavone having hydroxyl groups only at position 5 and 7 or 5,7-dihydroxyflavone is known as chrysin. In this study, crude chrysin had been successfully synthesized in 3 steps from phloroglucinol as starting material. Phloroglucinol was acetylated with acetonitrile and HCl gas, resulting phloroacetophenone amount to 74%. Phloroacetophenone benzoylation with 4.5 equivalents of benzoyl chloride produced tribenzoyl phloroacetophenone in 103–107% of yield and the subsequent Baker-Venkataraman rearrangement of the ester by using KOH in dried pyridine produced crude chrysin, with conversion percentage of 71.62%. All synthetic products had been characterized by melting point and spectroscopically.
