  Objective: The objective of this research was to investigate the anti-inflammatory effect of Mahkota Dewa fruit pericarp extract (Phaleria macrocarpa) on inducible nitric oxide synthase (iNOS) in mice colon induced by dextran sodium sulfate (DSS).Method: The simplisia of P. macrocarpa pericarp was weighed (1000 g) and extracted by maceration process. The total yield of the ethanolic extract was 26.43%. Phytochemical screening was carried out for the detection of the phytoconstituents by simple qualitative methods. The anti-inflammatory activity was performed by DSS-induced colitis model through assessment of hematoxylin-eosin staining and expression of iNOS by immunohistochemistry assay at four different doses, i.e., 650, 1250, 2500, and 5000 mg/kg. Swiss Webster male mice weighing 25-30 g were used for the study.Results: Inflammation score in dose 625, 1250, 2500, and 5000 mg/kg were 1.63, 1.43, 1.32, and 2.20, respectively. This result is significantly different (p=0.008) with DSS group that was 4.37. The results of iNOS optical density score in dose 625, 1250, 2500, and 5000 mg/kg were 1.21, 1.119, 1.22, and 1.37, respectively. This result was significantly different (p=0.000) with DSS group that was 2.24.Conclusion: Pericarp extract of P. macrocarpa fruit exhibited anti-inflammatory activity in the experimental model shown by suppressing the expression of inflammatory cell and iNOS.

Objective: The incidence of small intestine cancer (SIC) is rising despite available preventive measures. Kaempferol and quercetin are a potential chemopreventive agent for SIC, but in vivo findings are inconclusive. We aim to study the effects of kaempferol and quercetin on colitis-associated small intestine carcinogenesis in mice.Methods: Suppression effect was tested using mice divided into 6 groups of treatment, i.e.; normal (N) group, negative control (NC), leaf extract (medium dose [MD]) dose 12.5 and 25 mg/kg body weight (BW), leaf extract chitosan and nanoparticle of mahkota dewa (NPMD) dose 6.25 and 12.5 mg/kg BW. Dextran sulfate sodium induction of 1% w/v was administered through drinking water for 6 weeks of treatment. The suppression effect was observed histopathologically by counting the mitotic cells and hyperplasia cells of the crypt of small intestine with hematoxylin-eosin staining.Results: Mitosis cells mean of NC group was not significant difference either with MD 12.5 (p=0.394) or MD 6.5 (p=0.310). However, mitosis cell mean appears to be lower in the NPMD 12.5 (p=0.09) and NPMD 6.25 (p=0.05) groups than the NC group. There was a significant difference among the mean of hyperplasia NC group and MD and also NPMD group. Significant difference also can be showed between MD 12.5 and MD 25 (p=0.026), and between NPMD 6.25 and NPMD 12.5 (p=0.002), and between MD 12.5 and NPMD 12.5 (p=0.002).Conclusion: Our results demonstrate suppression of hyperplasia small intestine by either nanoparticle or extract of Phaleria macrocarpa extracts. The suppression of mitosis was showed by administration of nanoparticle.

AbstrakPenyakit jantung koroner (PJK) merupakan penyebab utama kematian di berbagai belahan dunia termasuk di Indonesia. Salah satu pemicu terjadinya PJK adalah tingginya kadar kolesterol dalam darah. Buah mahkota dewa telah lama digunakan oleh masarakat untuk menurunkan kadar kolesterol dan mengobati berbagai penyakit kardiovaskuler.Telah dilakukan penelitian untuk melihat efek infus buah mahkota dewa terhadap pencegahan peningkatan kadar kolesterol pada tikus putih jantan yang diberi diet lemak tinggi (DLT). Penelitian ini menggunakan 30 ekor Rattus novergicus jantan yang berumur 2,5 – 3 bulan dengan berat badan 250 - 350 gram. Hewan coba dibagi secara acak atas lima kelompok dan diperlakukan sebagai berikut:Kelompok I diberi diet standar 555 global feed dan 1 ml aquades, kelompok II diberi diet lamak tinggi(DLT) yang terdiri dari 2% Kolesterol, 10% kuning telur itik, 18% lemak sapi dan 78% diet standar dan 1 ml aquades, kelompok III diberi DLT dan 1 ml infus yang mengandung 97 mg mahkota dewa., kelompok IV diberi DLT dan 1 ml infus yang mengandung 194 mg mahkota dewa, kelompok V diberi DLT dan 1 ml infus yang mengandung 388 mg mahkota dewa. Infus diberikan per oral setiap hari selama 56 hari. Diet dan air minum diberikan ad libitum.Pada hari ke 0, 14, 28, 42 dan 56 darah diambil melalui vena centralis ekor untuk ditentukan kadar kolesterol totalnya secara enzimatik menggunakan KIT kolesterol CHOD-PAP merk Diasys. Absorbans diukur dengan spektrofotometer Genesis 20 pada panjang gelombang 546 nm. Data dianalisis dengan GLM pengukuran berulang dan one-way anova.Hasil penelitian menunjukan : pemberian infus yang mengandung 97, 194 dan 388 mg mahkota dewa dapat mencegah peningkatan kadar kolesterol dibanding kontrol (-). Terdapat perbedaan yang signifikan (p<0,05) antara kelompok 194 dan 388 mg dengan kelompk 97 mg, dimana kelompok 194 dan 388 mg mencegah peningkatan lebih besar. Tidak terdapat perbedaan (p>0,05) antara kelompok yang mendapat 194 dengan kelompok yang mendapat 388 mg mahkota dewa.ARTIKEL PENELITIAN52Disarankan untuk meneliti efek pencegahan peningkatan pada profil lipid yang lain dan melihat efek penurunan infus mahkota dewa pada hewan coba yang hiperkolesterolemik.Kata kunci : Mahkota dewa, kolesterolAbstractCoronary heart disease (CHD) is the leading cause of death in many parts of the world including in Indonesia. One of the triggers of CHD are high blood cholesterol levels. The Crown of God (Phaleria macrocarpa) has long been used by people to lower cholesterol and treat various cardiovascular diseases. Has done research to observe the effect of infusion Phaleria to prevent an increase in cholesterol levels in male white rats fed a high fat diet (HFD). This study used 30 male Rattus novergicus old from 2.5 to 3 months with body weight 250-350 grams. Experimental animals were randomized over five groups and treated as follows:Group I was given a standard diet 555 of global feed and 1 ml aquades, group II were given a diet high fat (HFD) consisting of 2% cholesterol, 10% of duck egg yolk, beef 18% fat and 78% standard diet and 1 ml aquades, group III was given the DLT and 1 ml infusion containing 97 mg of crown gods., group IV were given DLT and 1 ml infusion containing 194 mg crown of god, group V were given HFD and 1 ml infusion containing 388 mg the crown of god. Infusion given orally every day for 56 days. Diet and drinking water provided ad libitum.On days 0, 14, 28, 42 and 56 blood was collected via the tail vein centralis for total cholesterol is determined enzymatically using cholesterol Chod-PAP KIT Diasys. Absorbance was measured with a spectrophotometer Genesis 20 at 546 nm wavelength. Data were analyzed by GLM repeated measurements and one-way ANOVA.The results showed: the infusion containing 97, 194 and 388 mg crown of god can prevent an increase in cholesterol levels compared to controls (-).There are significant differences (p <0.05) between groups 194 and 388 mg with 97 mg faction, which groups 194 and 388 mg prevent the increase is greater. No difference (p> 0.05) between the group receiving 194 with the group receiving 388 mg crown of gods.It is advisable to examine the effect of preventing an increase in other lipid profiles and observe the effect of decreasing infusion crown of gods on hypercholesterolemic animal.Key word : Phaleria macrocarpa, cholseterol

Mahkota dewa (Phaleria macrocarpa [Scheff.] Boerl.) is an Indonesians traditional medicinal plant used to treat various diseases, such as diabetes mellitus, hemorrhoid, impotency and cancer. Almost all parts of the plants canbe used as traditional medicine, but if directly consumed, it can cause swollen, sprue, numb at tongue, fever, even unconsciousness. This research was carried out to find out recovery of liver tissue damage of mice administered intraperitoneally with subchronic dosage of butanol extract 170 mg/kg body weight. Observation on first week showed that there is light degeneration (vacuolization) which is getting better on second week and apparentlynormal on forth week.
