Judul: Efek Tepung Delima (Punica granatum L.) sebagai Sumber Antioksidan pada Metabolisme Tikus Putih (Rattus norvegicus) yang Dikontaminasi Asap Rokok, Effect of Pomegranate Powder as Antioxidant Source on Metabolism of White Rat (Rattus norvegicus) Contaminated with Cigarette Smoke
Abstrak: The effect of pomegranate fruit and seed powder as a source of antioxidant on consumption, digestion of lipid and crude fiber are evaluated in this study. Thirty of 28 day old rats were used in this experiment. This experiment used completely randomized design with three treatments and ten replications. The experimental rats were given diets containing pomegranate at levels of 0% (R0= control diet), 5% (R1= R0 containing 5% pomegranate fruit and seed powder) and 10% (R2= R0 containing 10% pomegranate fruit and seed powder). Variables measured were ether extract, crude fiber, NFE intakes and digestibilities and abdominal circumference. Data were analyzed with Analysis of Variance (ANOVA) and differences among treatments were tested by contrast orthogonal tests. Results show treatments affected nutrient intakes (P<0.01), but did not produced significant effect on nutrient digestibilies. There were no significant effect of treatments on the change in abdominal circumference. In conclusion, the use of pomegranate fruit and seed powder increased fat and carbohydrate intake in mice contaminated with cigarette smoke; however there were no effect on fat and carbohydrate digestibilities, and the change in abdominal circumference. The best result was produced by R1 which contained 5% pomegranate fruit and seed powder.

Judul: Aktivitas hepatoproteksi Ekstrak Polifenol Buah Delima (Punica granatum L.) Terhadap Tikus Putih yang Diinduksi Parasetamol
Abstrak: The patient of liver disease more increase. Pomegranate has been higher antioxidant activities and reported as hepatoprotection. The research to make for activity pomegranate polifenol as hepatoprotector and influence in liver histopathology of rat to induction by paracetamol. Polyphenol extracted by mixture solvent acetone:water:acetid acid (90:9.5:0.5). There are 22 rats randomly divided into 7 following group, they are group I allowed fed with strandard pellet, group II allowed fed with strandard pellet and paracetamol 500 mg/kg BB, group III allowed fed with strandard pellet, paracetamol 500 mg.kg BB, and cursil-70 13.3 mg/kg BB, group IV, V, VI, and VII allowed fed with strandard pellet, paracetamol 500 mg/kg BB, and extract polyphenol of pomegranate with doses 13.3 mg/kg BB, 100 mg/kg BB, 250 mg/kg BB, and 500 mg/kg BB for severally group. Experiment was conducted for 34 days and at the last day, observed liver histopathology about number of necrotic cells, apoptosis cells, kupfer cells, and fatty degeneration. Polyphenol extract of pomegranate with dose 500 mg/kg BB to point out possible chase destruction of liver (p<0.05) because number of necrotic cells is low, nothing apoptosis cells, number of kupfer cells is low, and fatty degeneration is low
