Judul: The red blood cells profile of infected  javanese thin  tailed sheep  with  haemonchus  contortus  larvae  infective
Abstrak: Penelitian ini bertujuan untuk mengetahui pengaruh derajat infeksi H. contortus terhadap gambaran jumlah sel darah merah, kadar hemoglobin dan nilai hematokrit pada domba ekor tipis. Sebanyak 20 ekor domba ekor tipis jantan berumur 6–8 bulan dikelompokkan menjadi lima kelompok yaitu kelompok kontrol tidak diinfeksi larva infektif (L 3 ) dan kelompok infeksi L3 dengan dosis 500 L3 , 1000 L3 , 2000 L3 dan 4000 L3 . Sampel darah dan tinja dikumpulkan sekali setiap minggu selama tujuh minggu setelah infeksi. Sampel darah diperiksa untuk mengetahui jumlah sel darah merah, kadar hemoglobin dan nilai hematokrit. Sampel tinja juga diperiksa untuk menghitung jumlah telur tiap gram tinja. Hasil penelitian menunjukkan bahwa dosis infeksi L 3 mempengaruhi nilai hematokrit (P<0.05), namun tidak mempengaruhi jumlah sel darah merah dan kadar hemoglobin (P>0.05). Jumlah telur tiap gram tinja (TTGT) berkorelasi negatif namun lemah dengan jumlah sel darah merah, kadar hemoglobin dan nilai hematokrit (P<0.05; R<0.50)., This research was conducted to investigate the effect of H. contortus infection to red blood cell profil of Javanese thin tail sheep. The total of 20 males of Javanese thin tailed sheep age 6-8 months were grouped into five groups namely not infected control group and infective group of 500 L 3, 1000 L 3, 2000 L 3 and 4000 L 3 . The samples of blood and fecal were collected weekly for seven weeks. The blood samples were examined to determine the total of red blood cells, hemoglobin levels and pack cell volume, whereas fecal samples to determine egg per gram. The results showed that the infection dose had the effect to pack cell volume, but the total of red blood cells and hemoglobin levels were not significantly different. The amount of egg per gram were negatively correlated with the red blood cells, hemoglobin level and pack cell volume.

Abstrak: The aim of this study was to investigate the effect of Haemonchus contortus infection to white blood cell profile of Javanese thin tail sheep. Twenty males Javanese thin tailed sheep were divided into five groups, namely infected group of 500 L3, 1000 L3, 2000 L3, 4000 L3 and uninfective group as control. The blood and fecal samples were collected from rectum before and three weeks after infection. The blood samples were collected using venoject® from Jugular vein. The fecal samples were collected directly from rectum. The blood samples were examined to determine total of white blood cell (leukocytes) and white blood cell differential, whereas fecal samples to determine egg per gram. The result showed that Haemonchus contortus infections cause an increased total of leukocyte but were not significantly different among of level infection doses (P>0.05). Number of eosinophils were significantly different among uninfected group (P<0.05), but were not significantly different in number of lymphocyte, monocyte, and neutrophil (P>0.05). There where positively correlated significantly between the amount of egg per gram (EPG) and profile of eosinophil (P<0.05), however were negatively correlated significantly between the amount of egg per gram (EPG) and neutrophil’s profile (P<0.05). There where no correlation significantly between the amount of egg per gram (EPG) and profile of white blood cell, lymphocyte, and monocyte (P>0.05).

Judul: Sintesis 1-Kloro-2-metoksi-6-propilnaftalena-1,3-dioksolana (1:1) sebagai Prekursor Asam (S)-(+)-(6-Metoksi-2-naftil)propanoat
Abstrak: Senyawa 1-kloro-2-metoksi-6-propilnaftalena-1,3-dioksolana (1:1) sebagai prekursor asam (S)-(+)-(6-metoksi-2-naftil)propanoat disintesis dari bahan awal 2-metoksinaftalena. Tahapan sintesis diawali dengan klorinasi menggunakan 2 jenis pereaksi klorinasi, yakni isosianurat terklorinasi dan NaOCl. Klorinasi dengan isosianurat terklorinasi berhasil menyintesis 1-kloro-2-metoksinaftalena sebagai produk monoklorinasi melalui pencirian dengan kromatograf gas-spektrometer massa (GC-MS). Nisbah konversi produk paling efisien diperoleh pada laju penambahan 2.5 mmol/jam. Sebaliknya, klorinasi dengan NaOCl menghasilkan produk triklorinasi. 1-Kloro-2-metoksinaftalena selanjutnya diasilasi dengan propanoil klorida, tetapi analisis dengan GC menunjukkan bahwa produk asilasi tidak terbentuk. Sistem bebas-air diperlukan untuk keberhasilan proses asilasi tersebut.
