Abstract

Background: Nasopharyngeal carcinoma (NPC) characteristically harbors many tumor-infiltrating lymphocytes. In biopsies of Hodgkin or anaplastic large cell lymphoma many activated CTLs are related to a very poor clinical outcome, suggesting that in these cases with a strong CTL mediated anti-tumor cell response, selection occurs for tumor cells that have become resistant to CTL and chemo and/or radiotherapy induced apoptosis. Only activated CTLs and natural killer cells express granzyme B.Objective. Since, similar to lymphomas, the prognosis of NPC patients depends primarily on the sensitivity of tumor cells to radio- and/or chemotherapy, this study investigated whether the presence of many tumor-infiltrating activated CTLs in tumor biopsies also predicts poor prognosis in NPC patients.Methods: The study investigated 39 specimens of Indonesian NPC patients that fulfilled the following criteria; no evidence of distant metastases at the time of diagnosis, and complete remission following complete radio- and/or chemotherapy. Number of tumor-infiltrating activated CTLs was detected using a combination of antibodies against granzyme Band CD3, CD8 and CD56.Results: The presence of a high number of tumor infiltrating activated CTLs expressing granzyme B appeared to be a very strong predictor of a rapid fatal clinical outcome. Its prognostic value was stronger than and independent from the other prognostic makers; age and clinical TNM stage at presentation. Prognosis was found to decline strongly with increasing percentage of activated CTLs. The most informative cut-off value was found to be 25%. The median overall survival time of patients with

Abstract

Astrocytes of hippocampus contribute in the learning performance. Entrainment of gamma wavescan improve learning performance by improving the neurons to astrocytes communication. Theaim of this study was to evaluate the effect of binaural entrainment of 2000-2040 Hz and 2000-2090 Hz on Glial Fibrillary Acidic Protein (GFAP) expression in astrocytes of the CA1 region ofrat hippocampus during operant learning conditions. Twenty male Wistar rats aged 4-6 weekswith body weight 100-150 g were devided into 4 groups. Group I was given binaural soundsentrainment at 2000-2040 Hz without learning test. Group II was given entrainment as performedin Group I followed by a learning test. Group III was given binaural sounds entrainment at 2000-2090 followed by a learning test. Group IV was not given entrainment nor learning test. Theentrainment was performed for 30 minutes everyday for 12 days and the learning test wasperformed for 10 minutes everyday for 12 days. The GFAP expression was examinedimminohistochemically. Astrocytes processes and astrocytes histoscore were also calculated.The results showed that the number of the GFAP-positive astrocytes in Group I (70.96 ± 4.86),II (69.76±3.07) and III (63.10±5.85) were significantly higher than Control (47.33±1.33)(p<0.05). The number of the processes astrocytes in Group I (47.64 ± 3.87), II (60.66±2.07)and III (54.17±6.38) was significantly higher than Control (30.87±2.69) (p<0.05). Moreover,the number of the processes astrocytes in Group II was significantly higher than Group I (p=0.016).The astrocytes histoscore index in the Group II (115.58±14.13) and III (78.32±22.23) weresignificantly higher than Group I (28.79 ± 9.61) and Control (16.05±1.64) (p<0.05). Inconclusion, the binaural entrainment of 2000-2040 Hz and 2000-2090 Hz increase GFAP expressionof astrocytes in Cornu Ammonus 1 (CA1) region of rat hippocampus during operant learningconditioning.

Abstract

Latar belakang: Karsinoma Nasofaring (KNF) adalah keganasan dengan distribusi etnis dan geografis yang khas. KNF memiliki karakteristik yang berbeda dari kanker kepala dan leher lainnya,seperti perilaku pertumbuhan yang cepat, kecenderungan yang tinggi untuk bermetastasis ke kelenjargetah bening (KGB) regional dan organ jauh. E-cadherin memainkan peran penting dalam pemeliharaanadhesiantar sel-sel epitel. Perubahan molekul adhesi sel E-cadherin yang dimediasi oleh sel-sel kankerberkontribusi untuk peningkatan penyebaran sel tumor dan pembentukan metastasis. Tujuan: Untukmengetahui perbedaan ekspresi E-cadherin pada KNF yang telah bermetastasis dengan KNF yang belumbermetastasis. Metode: Desain penelitian adalah studi kasus-kontrol. Subjek penelitian adalah blok parafindari pasien KNF yang telah menjalani biopsi. Blok dari pasien KNF yang telah bermetastasis dikategorikansebagai kelompok kasus, sementara yang tidak bermetastasis sebagai kelompok kontrol. Sampel dari keduakelompok diperiksa dengan metode imunohistokimia (IHK) menggunakan antibodi E-cadherin. Hasil:Sampel 48 blok parafin, masing-masing kelompok terdiri dari 24 blok. Terdapat perbedaan yang signifikanekspresi E-cadherin dengan p<0,001 dan Odds Ratio (OR) 87,4 (95% interval kepercayaan 10,15-2653,26).Terdapat pula hubungan yang signifikan antara penurunan ekspresi E-cadherin dengan status KGB leher(p<0,001), metastasis jauh (p=0,001), dan stadium penyakit (p=0,001). Kesimpulan: Terdapat perbedaanyang signifikan antara ekspresi E-cadherin pada kelompok KNF yang telah bermetastasis dibandingkankelompok KNF yang belum bermetastasis. Kata kunci: Karsinoma nasofaring, ekspresi E-cadherin, metastasisABSTRACT Background: Nasopharyngeal carcinoma (NPC) is a malignancy with distinct ethnic and geographical distribution. NPC has different characteristics from other head and neck cancers, suchas rapid growth behavior, high propensity to metastasize to regional lymph nodes and distant organs.E-cadherin plays an important role in the maintenance of cell adhesion between epithelial cells. Changesin the cell adhesion molecule E-cadherin mediated by cancer cells contributes to increase in the spreadof tumor cells and the formation of metastasis. Purpose: To determine the difference in the expressionof E-cadherin between NPC that has metastasized and NPC that has not metastasized. Method: Acase-control study. Subjects were paraffin blocks from NPC patients who had undergone biopsy. Blocksfrom NPC patients who had metastasized categorized as a group of cases, while not metastasized as acontrol group. Samples from both groups were examined using immunohistochemistry method (IHC)with antibody E-cadherin. Result: Samples were 48 paraffin blocks, each group consisted of 24 blocks.There was a significant difference between the expression of E- cadherin with p<0.001 and Odds Ratio(RO) 87.4 (95% confidence interval 10.15 to 2653.26). There was also a significant correlation betweenreduced expression of E-cadherin with neck lymph node status (p<0.001), distant metastasis (p=0.001),and stage of disease (p=0.001). Conclusion: There was a significant difference between the expressionsof E-cadherin in NPC that had metastasized with the NPC that had not metastasized.

Abstract

A study of ambonese plantain banana (Musa paradisiaca var sapientum Lamb) treatment in burn wound healing on the skin of white rats (Rattus novergicus) has been conducted. The wound healing of burn injuries was evaluated by counting the number of PMN leukocytes and fibroblasts at the 7th, 14th, and 21st days following the treatment. The study showed that the decrease in number of PMN leukocytes of subjects treated with ambonese plantain banana was relatively more significant compared to both negative and positive control (Bioplacenton ®). In contrast, an increasing number of fibroblasts was significantly demonstrated at the 14th and 21st days after treatment. In conclusion, ambonese plantain banana treatment in burn injuries will provide better results compared to both positive and negative controls.
