Efek Pemberian Gula Kelapa yang Diperkaya Minyak Sawit Merah terhadap Peningkatan Berat Badan dan Kadar Retinol Serum Tikus Defisien Vitamin A (Effect Of The Feeding Of Brown Sugar Enriched With Red Palm Oil On Body Weight Gain And Serum Retinol Levels

Vitamin A deficiency (VAD) is an important cause of blindness and premature death. Vitamin A also plays an important role on growth and immune function. Red palm oil is the richest naturally occurring source of β-carotene, a carotenoid that the human body can convert into USAble vitamin A (retinol). This research was to evaluate the effect of feeding red palm oil enriched brown sugar on improving body weight and serum retinol level of vitamin A depletion Sprague-Dawley rats. Twenty four of six weeks old-male Sprague Dawley rats were used. After 2 weeks of adaptation period, rats were given vitamin A deficient diet (modified AIN-93M) for 10 weeks, and then divided into 3 groups and received for 2 weeks the different treatment as repletion period: 1) RPO group which received red palm oil enriched brown sugar (1.5 mL/d), 2) CPO group which received crude palm oil enriched brown sugar (1.5 mL/d) and 3) and RE group which received retinyl palmitate (0.6 mL/d) . Each treatment contains approximately 40 µg beta carotene/day. Intervention by feeding brown sugar enriched with RPO and CPO for 2 weeks can increase the body weight of rats by 3.54 percent and 5.23 percent, respectively, which is markedly better than the group that was given retynil palmitat (9.38%) (p<0.05). However, an increase in serum retinol concentrations in all group showed no significant differences (p>0.05). Consumption of brown sugar enriched with RPO or CPO enhances body weight and serum retinol concentration of vitamin A deficient rats

Rescue with an anti-inflammatory peptide of chickens infected H5N1 avian flu

Chickens suffering from avian flu caused by H5N1 influenza virus are destined to die within 2 days due to a systemic inflammatory response. Since HVJ infection (1,2) and influenza virus infection (3,4) cause infected cells to activate homologous serum complement, the systemic inflammatory response elicited could be attributed to the unlimited generation of C5a anaphylatoxin of the complement system, which is a causative peptide of serious inflammation. In monkeys inoculated with a lethal dose of LPS (4 mg/kg body weight), inhibition of C5a by an inhibitory peptide termed AcPepA (5) rescued these animals from serious septic shock which would have resulted in death within a day (6). Therefore, we tested whether AcPepA could also have a beneficial effect on chickens with bird flu. On another front, enhanced production of endothelin-1 (ET-1) and the activation of mast cells (MCs) have been implicated in granulocyte sequestration (7). An endothelin receptor derived antisense homology box peptide (8) designated ETR-P1/fl was shown to antagonize endothelin A receptor (ET-A receptor) (9) and reduce such inflammatory responses as endotoxin-shock (10) and hemorrhagic shock (11), thereby suppressing histamine release in the circulation (12). Thus, we also administered ETR-P1/fl to bird flu chickens expecting suppression of a systemic inflammatory response

The Effects of Carbon Tetrachloride Administration on Liver and Renal Function

Carbon tetrachloride (CCl4) that induces liver damage is widely used in hepatoprotector experiments. Carbon tetrachloride at a single dose 0,1; 1,0; and 10 ml/kg body weight was administrated intraperitoneally in male rats to investigate liver and renal damage. Liver damage was monitored by increased alanine transaminase (ALT), aspartate transaminase (AST), alkaline phosphatase (ALP), total bilirubin, and serum total protein. Increased serum creatinine is an indicator of renal problem. Futhermore, liver and renal tissues were subjected to histopathological studies. Compared with control, injection of 0,1 and 1,0 ml CCl4/kg body weight increased ALT and decreased AST, and at dose 10 ml/kg body weight both ALT and AST decreased to a greater extent (p<0.05). Alkaline phosphatase, total bilirubin, and total protein were not different in all treatments (p>0.05). Carbon tetrachloride at dose 0,1 and 1,0 ml/kg body weight increased creatinine. However, injection of 10 ml CCl4/kg body weight decreased creatinine (p<0.05). Histopathological studies confirmed the presence of steatosis in hepatic cells at single dose of 1,0 and 10 ml CCl4/kg body weight, with no significant effect in glomerulus. Administration of single dose of CCl4 can induce liver and renal damage that dependent on CCl4 received.&nbsp

Studi Beberapa Penyakit yang Ditemukan Bersama dengan Gumboro/infectious Bursal Disease

Pengamatan terhadap 43 kasus Gumboro di Laboratorium Patologi Unggas FKH IPB pada tahun 1991 menunjukkan bahwa penyakit Gumboro dapat terjadi pada ayam pedaging maupun ayam petelur dengan kisaran umur 7-60 hari. Kehadiran Gumboro daapt menyebabkan penurunan fungsi tanggap kebal sehingga ayam lebih peka terhadap infeksi penyakit lain. Hasil kajian yang diperoleh adalah: Gumboro dapat berdiri sendiri (30.23%) atau disertai penyakit lain; seperti ND (30.23%), CRD (9.30%), Coccidiosis (6.98%), Colibacillosis (4.67%), ND dan CRD (13.95%), ND dan Coccidiosis (2.32%), CRD dan Coccidiosis (2.32%)

Aktivitas Anticestoda in Vitro Metabolit Sekunder Daun Miana (Coleus Blumei. Benth) Terhadap Cacing Hymenolepis Microstoma

Penelitian ini untuk mengetahui golongan senyawa metabolit sekunder dari ekstrak daun miana (Coleus blumei. Benth) yang memiliki aktivitas anticestoda. Daun miana kering diekstraksi dengan metode yang sesuai untuk mendapatkan golongan senyawa metabolit sekunder alkaloid, flavonoid, tanin, dan steroid. Aktivitas anticestoda diukur dengan menghitung waktu kematian cacing Hymenolepis microstoma pada setiap golongan metabolit sekunder konsentrasi 10%. Hasil penelitian menunjukkan tanin memiliki aktivitas anticestoda yang kuat yang tidak berbeda dengan praziquatel sebagai anthelmintik komersial. Akivitas anticestoda flavonoid mirip dengan tanin akan tetapi aktivitasnya masih dibawah praziquatel. Alkaloid dan steroid memiliki aktivitas anticestoda yang lebih rendah dibandingkan dengan tanin dan flavonoid. Hasil penelitian ini membuktikan bahwa tanin sebagai senyawa metabolit sekunder yang paling aktif sebagai anticestoda dibandingkan flavonoid, alkaloid, dan steroid
