Abstract

Latar belakangTumor phyllodes adalah neoplasma stromal-epitelial yang jarang ditemui, secara histologis dibedakan menjadi benign, borderline, malignant. Patogenesis tumor phyllodes belum jelas. CD117 merupakan reseptor tirosin kinase yang terletak di membrane sel dan berperan dalam proses patogenesis suatu keganasan, sedangkan Ki-67 terlibat dalam jalur proliferasi sel. Tujuan penelitian ini menganalisis adanya perbedaan ekspresi CD117 dan Ki-67 pada tumor phyllodes yang benign, borderline, malignant.MetodePenelitian ini adalah observasional analitik dengan pendekatan cross sectional. Masing-masing sepuluh sampel tumor phyllodes benign,borderline dan malignant diambil acak dari arsip histopatologi RSUD Dr. Soetomo Surabaya periode Januari 2009-Juli 2014, lalu dilakukan pulasan immunohistokimia dengan antibodi poliklonal CD117 dan monoklonal Ki-67. Perbedaan ekspresi CD117 dan Ki-67 pada tumor phyllodes benign, borderline dan malignant dianalisis menggunakan uji Kruskal-Wallis dan Mann-whitney. Korelasi antara ekspresi CD117 dan Ki-67 pada tumor phyllodes dianalisis menggunakan uji Spearman.HasilUji Kruskal-Wallis ekspresi CD117 antara tumor phyllodes benign dan malignant menunjukkan perbedaan bermakna. Uji Mann-Whitney ekspresi Ki-67 antara tumor phyllodes benign, borderline, dan malignant menunjukkan perbedaan bermakna, sedangkan uji Spearman antara ekspresi CD117 dan Ki-67 menunjukkan perbedaan bermakna.KesimpulanEkspresi CD117 dan Ki-67 dapat digunakan untuk membedakan tumor phyllodes benign, borderline, dan malignant.

Abstract

BackgroundBroad spectrum tumors can arise in salivary glands, giving diagnostic difficulties in some subtypes due to morphological similarities. Immunohistochemistry studies done to differentiate between benign and malignant neoplasms of salivary glands are very few, including Cdk6 and Ki-67. Cdk6’s role in tumorigenesis is halting cellular proliferation and differentiation. Ki-67 is actively expressed in proliferating cells, particularly neoplasms. The objectives are to analyze differences of Cdk6 and Ki-67 expression in benign and malignant salivary gland neoplasms and to analyze the correlation between those two proteins.MethodsThis is an analitic observational study with cross sectional design. Samples were taken proportionally, each 15 samples of benign and malignant salivary gland neoplasms, derived from pathological archives during 1 January 2011-30 June 2013 period. Immunohistochemical staining with Cdk6 and Ki-67 monoclonal antibody were performed. Differences in Cdk6 and Ki-67 expression of both groups were analyzed using Mann Whitney. The correlation between the Ki-67 and Cdk6 expression were analyzed using Spearman.ResultsThere were significant differences in the Cdk6 and Ki-67 expression between benign and malignant salivary gland neoplasms.The expressions of Ki-67 have a cut-off point of 6.50%. There was a significant correlation between Cdk6 and Ki-67 expression in the salivary gland neoplasms.ConclusionExpression of Cdk6 and Ki-67 were low at benign salivary gland neoplasms and high at malignant salivary glands neoplasms. There was significant correlation between Cdk6 expression and Ki-67 expression at benign and malignant salivary gland neoplasms. Although both could differentiate the behavior of neoplasms, Ki-67 was more reliable and applicable.

Abstract

Kanker kolorektum merupakan salah satu kanker yang tersering di dunia. Target molekuler untuk pengobatan kanker kolorektumyaitu Epidermal Growth Factor Receptor (EGFR) dengan pemberian antibodi monoklonal anti-EGFR. Pemberian pengobatan ini tidakdapat memberikan efek dampak di pasien dengan status gen KRAS bentuk mutan, sehingga perlu dilakukan pemeriksaan status mutasigen KRAS. Telitian berupa deskriptif dengan pendekatan potong lintang yang bertujuan untuk mendapatkan data status mutasi genKRAS kodon 12 dan 13 di pasien adenocarcinoma colorectal. Deteksi mutasi KRAS dilakukan dengan teknik Polymerase Chain ReactionRestriction Fragment Length Polymorphism (PCR RFLP) yang dikonfirmasi dengan sekuensing. Sampel telitian adalah 30 blok parafinyang diperoleh dari Rumah Sakit Dr.Soetomo Surabaya masa waktu Januari-Desember 2013. Setelah dilakukan ekstraksi DNA terdapat21 sampel yang dapat digunakan untuk pemeriksaan lanjutan. Hasil PCR RFLP menunjukkan terdapat 7/21 mutasi pada kodon12 dan tidak terdapat mutasi gen KRAS pada kodon 13. Mutasi pada kodon 12 yaitu GGT>GCT, GGT>GGA dan GGT>GAT yangmenyebabkan perubahan asam amino Gly12Ala, Gly12Gly dan Gly12Asp. Simpulan telitian ini adalah mutasi gen KRAS kodon 12 padaadenocarcinoma colorectal di Rumah Sakit Dr. Soetomo Surabaya sebanyak 33%.

Abstract

Background: Disruption to healing process results on longer healing duration from the timeline. Povidoneiodine and tulle are common management in wound care. The advance of industry in health sector andthe availability of natural ingredients in Indonesia provide opportunities for developing alternatives forwound care. Turmeric (Curcuma longa) contains curcumin which is anti-inflammatory, antibacterial,and antioxidant; it is good for wound healing. Hydrogel nanocomplexes of carboxymethyl chitosan canmaintain moisture in wound area and protect curcumin from hydrolysis. Objective: To analyze the potentialof turmeric extract loaded hidrogels in accelerating wound closur. Method: experimental research with“post-test only control group design”. The sample consisted of 30 mice which were assigned into 5 groups.Result: All experimental groups experienced a gradual decrease in wound length. The statistical test resultsfor groups II and III showed significant advantages compared to group IV (p<0.05). Meanwhile, group Idid not have significant differences in wound closure compared to group IV on day 1 and 3 (p>0.05), but ithad significant results (p<0.05) on day 5. Conclusion: Turmeric extract loaded hidrogels can accelerate thereduction of wound length.

Abstract

Background: Diabetes mellitus is a chronic disorder caused by elevated levels of high blood glucose(hyperglycemia). This chronic hyperglycemia causes ROS to accumulate and oxidative stress to increase.Rosa damascena is a plant that contains high levels of antioxidants and polyphenols, but this is not widelyknown to the public. Purpose: The aim of this study is to understand the hypoglycemic effects from Rosadamascena on blood glucose levels and diameter of Langerhans pancreatic islets. Method: Thirty Wistaralbino rats (200-225gr) were divided into 6 groups. Group 1 was a normal control (KN), group 2 washyperglycemic (KD), group 3 was metformin 250 mg/kg BW (KM), group 4 was treatment extract 250 mg/kg BW (P1), group 5 was treatment extract 500 mg/kg BW (P2) group 6 was treatment extract 1000 mg/kg BW (P3). All animals in the group were injected with STZ 50 mg/kg BW, except for group 1. Result:Data were analyzed statistically using SPSS- 22 software with the Kruskall-Wallis test (p<0.05). The resultshowed that ethanolic extract of Rosa damascena has decreased blood glucose levels in days-14 (382±21,97) with 250 mg/kg BW (P1) compare with another treatment group. In histological observed there areno significant different between group (p>0.05). This is showing that ethanolic extract of Rosa damascenahas inability to repaired the diameter of Langerhans pancreatic islets. Conclusion: Ethanolic extract of Rosadamascena decreased blood glucose levels but did not repaired the diameter of Langerhans pancreatic islets.
