Background: Mahkota dewa, [Phaleria macrocarpa (Scheff.) Boerl.] is an Indonesian indigenous plant from Papua. This plant is famous in Indonesia, empirically used to treat many diseases. In vitro study indicated that mahkota dewa could inhibit the growth of HeLa and leukaemic cells.

Aims : The present study was designed to investigate the anticancer activity of ethanol extract of mahkota dewa mesocarp fruit [Phaleria macrocarpa (Scheff.) Boerl.] , using in vivo experiment model of C3H mouse mammary tumor induced by transplantation.

Design :Thirty two C3H mice were randomly devided into 4 groups i.e. control and 3 groups of mice orally treated with 70 % ethanol extract of mahkota dewa mesocarp fruit, Dl (equivalent to 20 times human dose), D2 (equivalent to 40 times human dose) and D3 (equivalent to 80 times human dose) for 30 consecutive days, after tumor transplantation. Body weight and tumor volume periodically measured every week. Tumor weight was measured after the animal was sacrificed, fixed in formaldehyde and embedded in paraffin for histological preparation. The proliferation activity of tumor cell was examined by counting the AgNOR deposits detected after colloidal AgNOR staining. Index apoptosis was assessed by mean of Tunel method, and the width of necrotic area was identified by hematoxyllen eosin of the histological specimen.

Result and Conclusion : The result of analysis of variants showed that there were no statistical differences in tumor volume, tumor weights, AgNOR values and in the necrotic area among control and the three treated groups (p>0,05), except in the index apoptosis between control and D3 groups (p<0,05).

It can be concluded that oral administration of 3 doses of ethanol extract of mahkota dewa mesocarp fruit [Phaleria macrocarpa (Scheff.) Boerl.] 20, 40 and 80 times human dose for 30 consecutive days did not prevent the C3H mouse mammary tumor growth induced by transplantation (p>0,05) but there was the increased apoptosis in the group of receiving the fruit extract of 80 times human dose (p<0,05)."

"Latar belakang: Buah Merah (Pandanus conoideus Lam.) merupakan salah satu kekayaan biodiversitas alam Indonesia khas Papua yang sejak lama dikonsumsi sebagai makanan dan dikenal memiliki khasiat obat antara lain terhadap penyakit keganasan. Namun disisi lain, dasar ilmiah cara pengobatan tersebut belum diketahui secara pasti sehingga perlu dilakukan penelitian bagi pembenaran ilmiah pemakaian tanaman obat tersebut. Minyak Buah Merah diketahui mengandung beta karoten dan tokoferol yang tinggi. Berbagai penelitian menunjukkan tokoferol dapat menghambat pertumbuhan kanker payudara manusia pada kultur melalui induksi berhentinya sintesis DNA, diferensiasi sal, dan apoptosis. Karotenoid menurunkan pertumbuhan tumor payudara, meningkatkan ekspresi gen proapoptosis p53 dan BAX, menurunkan ekspresi gen antiapoptosis Bcl-2, dan meningkatkan rasio BAX:Bcl-2 pada tumor. Gen .repressor p53 dapat menginduksi cell cycle arrest sehingga memungkinkan terjadinya perbaikan DNA dan apoptosis.Tujuan: mengetahui pengaruh pemberian MBM per oral sebanyak 0,5ml, Iml, dan 2ml terhadap aktivitas apoptosis dan pertumbuhan tumor kelenjar susu mencit C3H.Rancangan penelitian: merupakan penelitian in vivo, digunakan 4 kelompok, 3 kelompok uji dan 1 kelompok kontrol, masing-masing 10 ulangan.

Background: Red Papua (RP) is one of the Indonesian natural properties. Originally, RP comes from Papua province. It is consumed by Papua people as daily food since a long time ago. RP is considered to be cancer medicine, particularly for breast cancer treatment. Alternatively, the justification on the use of RP as an anti cancer has not been established yet. Hence, scientific evidence on anticancer effect of RP is necessary. The previous study suggests that Red Papua Oil (RPO) contains a huge amount of carotene and of tocopherol. Some studies indicate that tocopherol can inhibit the growth of human breast cancer cell culture by prohibiting of DNA synthesis, induction of cell differentiation and apoptosis. Carotene reduces the rate of growth of breast tumor, improves gene expression of pro-apoptosis and p53 of BAX, degrades gene expression of anti-apoptosis Bcl-2, and increases the ratio of BAX: BCL-2. P53 gene can induce arrest cycle cell so that it enables cells to repair the DNA and generate apoptosis.Aims: to identify the influence of RPO intake of 0,5m1, 1m1, and 2ml doses per oral on apoptosis and its effect on tumor growth in mammary gland tumor of C3H strain mouse.Method: Twenty-four mice were randomly divided into four groups, three groups of RPO-treated groups and one control group. After tumor was transplanted, the three doses of RPO were given to the three groups. By twenty-eight day treatment, apoptosis and proliferation activities were measured_ TUNEL essay was used to detect apoptotic activity_ The tumor growth, which was determined by proliferation activity, was assessed by a histochemical technique, AgNOR (silver-staining nucleolar organizer regions). Statistical significance of Apoptosis Index (AI) and AgNOR value in control and groups treated with varied doses of RPO were calculatedResults and Conclusion: Variant analysis indicated that there was no significant difference of volume, weight and AI among control group and treated groups (p>0.05). However, there was a tendency to an increased apoptotic activity on the treated groups. On the contrary, AgNOR values were significantly different (p"

Chronic liver injury can be caused by a variety of infections, metabolic disorders, toxins or circulatory disorders which, if it continues, can become severe liver injury to cirrhosis of the liver if it does not receive adequate treatment. Besides that, the liver has a high regeneration ability to help with post-injury recovery. Various models of animal liver injury in rats tried specifically made to resemble chronic liver disease in humans. In this research, an experimental animal model was developed to study the process of liver regeneration using 2-AAF/CCl₄. 2-Acetylaminoflourene (2-AAF) which inhibits hepatocyte proliferation, while Carbon tetrachloride (CCl₄) is used to induce liver fibrosis and liver cirrhosis. After making 2-AAF/CCl₄ experimental animal models, human umbilical cord derived mesenchymal stem cells were given in the hope that they would have a positive effect on chronic liver injury assessed by parameters of ALT, albumin, anatomic and histological changes in rat liver tissue. In this study, in making animal models using male winstar rats by administering CCl₄ twice a week (2ml/kg) diluted in olive oil, administering subcutaneously for 12 weeks. Then combined with 2-AAF daily diluted in polyethylene glycol, administered intragastrically. The experimental group saw an increase in ALT levels, there was no difference in albumin levels, changes in the color of the liver became brighter with rough and boiled surfaces and had a larger size compared to controls that had hearts with dark red, slippery surfaces without nodules. Histopathological examination was also performed by staining HE, masson trichome and immunohistochemistry (expression of caspase 3), the results showed liver damage (fat degeneration, necrosis, cell swelling, inflammation and fibrosis of the liver, and death of hepatocytes). In groups given human umbilical cord derived mesenchymal stem cells can repair liver damage marked by a tendency to decrease ALT levels, tendency to increase albumin levels, anatomic improvements in the form of dark red heart color with a slippery surface, histological changes, namely tissue repair, decreased degrees of fibrosis and decreased mortality cell.

ABSTRACTBB.;Breast cancer is a multifactor disease that has been a leading cause of woman?s mortality. Treatments for breast cancer such as surgery, radiotherapy, and chemotherapy have their own side effects, so that alternative treatments such as herbal medicine are needed. Soursop leaf (Annona muricata Linn) has been reported to have antitumor and cytotoxic effects, but only few conducted in vivo, an advanced research is needed to find the effectiveness and the inhibition pathway of the soursop leaf. The purpose of this research is to find out the inhibition capacity and the effective dose of soursop leaf methanol extract (Annona muricata Linn) against the development of C3H mice?s breast cancer in vivo. There were thirty mice of C3H strain which were transplanted with breast tumor and they were divided into five groups consisting of negative control group which was given only solvent CMC 0.5%, a positive control group which was given doxorubicin, a dose group of 15 mg/kg BB, a dose group of 30 mg/kg BB, and a dose group of 45 mg/kg BB. Each mouse was given 0,2 cc soursop leaf extract every day for 21 days while the positive control group was given doxorubicin 0,03 μg/20 gram BB once a week for 21 days intravenously. The length and the width of the tumor were measured at the beginning and also measured once a week during the experiment process to gain the data of the tumor volume. At the end of the research, the tumor of the mice was lifted and weighed and it was stained by AgNOR to measure the proliferation activity of the cell. The Anova result showed that there was a significant difference (p=0,007) between treatment against the development of tumor which was marked by the decrease of the tumor volume and proliferation activity (p=0,001). The Kruskal Wallis result showed that there was no significant difference (p<0,33) in the tumor weight. Spearman correlation study significantly (p=0,03) indicated that there was a positive correlation between the cell proliferation activity and the growth of the tumor but in a weak correlation (r=0,39). Therefore, it could be concluded that the methanol extract of soursop leaf (Annona muricata Linn) can inhibit the growth rate of tumor volume as well as the proliferation activity of the breast cancer cell of C3H mice and it worked optimally at 30 mg/kg BB dose.;Breast cancer is a multifactor disease that has been a leading cause of woman?s mortality.

"[ABSTRAKLatar belakang: Malignant peripheral nerve sheath tumor (MPNST) adalah sarkoma jaringan lunak yang sulit dibedakan dengan beberapa sarkoma sel spindel karena morfologinya yang serupa. MPNST bersifat agresif dengan angka rekurensi yang tinggi dan cenderung bermetastasis terutama ke paru. Salah satu tahap metastasis adalah invasi dengan cara mendegradasi matriks ekstraseluler dimana Matrix Metalloproteinase (MMP) memainkan peranan penting dalam proses ini. MMP tipe gelatinase yaitu MMP-2 dan MMP-9 memiliki kemampuan dalam mendegradasi membran basal dan kolagen fibrilar sehingga dapat membuka jalur invasi bagi sel tumor. MMP-2 mampu mendegradasi lebih banyak tipe kolagen dan MES non kolagen dibandingkan MMP-9. Penelitian ini bertujuan untuk menilai hubungan antara peningkatan ekspresi MMP-2 dengan derajat keganasan histologik dan variabel prognostik klinis lainnya.Bahan dan cara: Dilakukan pulasan imunohistokimia MMP-2 pada 39 kasus yang terdiri atas 19 MPNST derajat rendah dan 20 MPNST derajat tinggi. Selanjutnya dilakukan analisis hubungan antara peningkatan ekspresi MMP-2 dengan derajat keganasan dan variabel klinis seperti usia, jenis kelamin, ukuran dan lokasi tumor.Hasil: Peningkatan ekspresi MMP-2 ditemukan pada 19 (95%) kasus MPNST derajat tinggi dan 3 kasus (15,8%) kasus MPNST derajat rendah (p=0.000). Terdapat hubungan yang kuat antara peningkatan ekspresi MMP-2 dengan derajat keganasan MPNST. Tidak ditemukan hubungan antara ekspresi MMP-2 dengan jeni usia, jenis kelamin, ukuran dan lokasi tumor.Kesimpulan: Peningkatan ekspresi MMP-2 sejalan dengan peningkatan derajat histologik, sehingga dapat digunakan untuk membantu menentukan progresifitas MPNST.

ABSTRACTBackground: Malignant peripheral nerve sheath tumor (MPNST) is a sarcoma that is difficult to differentiate with other spindle cell sarcomas, because of their similar morphology. The behavior of MPNST is aggressive, with a high recurrence and tend to metastases hematogenous, especially to lung. Important step of metastases is invasion by degradating extracellular matrix, in which Matrix Metalloproteinase (MMP) play important role in this process. Gelatinase type of MMP, MMP-2 and MMP-9 have ability to degrade basal membrane and fibriler collagen, in order to open the way of invasion. MMP-2 can degrade type collagen and non collagen extracellular matrix than MMP-9. The aim of this study is to see the correlation between expression of MMP-2 and histopathology grading and other prognostic clinical variables.Methods: This study enrolled 39 cases of consisted of 19 low grade MPNST and 20 high grade MPNST. The case were stained for MMP-2 imunnohistochemistry and the expression of MMP-2 were scored. Analysis the correlation between over expression of MMP-2 and histopathology grading and other clinical variables , such as age, sex, size and location of the tumor.Results: Overexpression of MMP-2 was observed in 19 (95%) cases of high grade MPNST and 3 (15,8%) cases of low grade MPNST (p=0.000). There is a significant correlation between MMP-2 over expression and histopathology grade. There is no correlation between MMP-2 expression and age, sex, siize and location of tumor.Conclusion: High expression of MMP-2 is in parallel with high histologic grade, therefore it may be of additional use as prognostic factor., ackground: Malignant peripheral nerve sheath tumor (MPNST) is a sarcoma that is difficult to differentiate with other spindle cell sarcomas, because of their similar morphology.

ABSTRACT

Background: Urothelial carcinoma comprises of 90% of all cases in bladder. There are two groups which are non invasive depend on whether the tumor has reached muscularis mucosa. 5-Years survival rate depend on grading and staging. Low malignant grade and non invasive can reach 90% survival rate, with recurrence rate 40-60%. High malignant grade and invasive tumor has only10-17% survival rate. Mitosis and lymphovascular invasion are related with recurrency. However, there are some controvesi regarding Bcl-2 expression in bladder urothelial carcinoma. This study aimed to evaluate different expression of Bcl-2 with 4 related factors contributy to survival, which are degree of malignancy, stage, mitosis, and lymphovascular invasion.

Material and methods: A retrospective and cross sectional study of urothelial carcinoma of the bladder was conducted in 2010-2014 in the Department of Anatomical Pathology, Faculty of medicine / RSCM. In this study found 21 cases of low grade and 21 cases of high high grade. Bcl-2 staining performed in all cases and percentages are calculated and made scoring 0-3.

Results: Most case is fifth decade as many as 27 cases. Obtained 4 cases found limfovaskuler invasion. This study obtains the relationship between mitosis with grade of tumor (p: 0.000). There were no differences between the expression of Bcl-2 with the degree of malignancy stage , mitosis and lymphovascular invasion.

Conclusions: There were no associated expression of Bcl-2 with the degree of malignancy, stage, mitosis, and invasion limfovaskuler."
