Abstract

Objective: To investigate the molecular pathway of the cytotoxic effect of SN-38 in human cervical cancer cell lines.Methods: Two human cervical cancer cell lines were treated with various concentrations of irinotecan for 24–72 hours and the sensitivity was analysed using the MTT assay. Apoptosis was further observed through microscopic examinations. The protein expression was determined using Western blot analysis.  Results: CaSki cells demonstrated the highest sensitivity to SN-38, whereas HeLa cells showed the lowest. In cervical cancer cells, SN-38 induced apoptosis through an intrinsic- and extrinsic-pathways. In addition, we showed that SN-38 downregulated the phosphorylation of Akt-mTOR pathways in CaSki cells, but not in HeLa cells. Interestingly, in HeLa cells, which were more suggestive of a resistant phenotype, pre-treatment with LY294002 and rapamycin inhibited activation of Akt-mTOR signaling and significantly enhanced the sensitivity of HeLa cells to SN-38. Conclusions: Irinotecan exerts its anti-neoplastic effects on cervical cancer cells by inducing apoptosis through caspase-cascade. Inhibition of Akt-mTOR, LY294002 and rapamycin, which is targeted to Akt-mTOR pathways, may sensitize irinotecan-resistant cervical cancer cells.Keywords: Akt-mTOR pathways anti-neoplastic drugs, cervix cancer cells, LY294002, rapamycin DOI: 10.15850/ijihs.v1n1.103

Abstract

Background: Melasma is hyperpigmentation of the skin especially located on face exposed to the sunlight. This condition was characterized by brown to gray-brown macula with irregular border. Difficulties in treatment of melasma arise from high tendency for relapse, expensive cost, and high risk of side effects such as erythema, sores, scales, and acne eruption. Study about evaluation of melasma therapy in Dr. Hasan Sadikin General Hospital Bandung have not ever been done before. Therefore, this study was conducted to evaluate therapy of melasma in the Policlinic of Dermatology and Venereology, Dr. Hasan Sadikin General Hospital Bandung.Methods: This study was retrospectively descriptive. Data were obtained from the new melasma patient medical records of Policlinic of Dermatology and Venereology of Dr. Hasan Sadikin General Hospital Bandung in period of January 2013–2014. Sampling method used in this study was total sampling. Treatments of melasma were evaluated by using Melasma Area Severity Index (MASI) score. Collected data were processed and presented in frequency distribution and percentage.Results: The most used topical drugs were combination of hydroquinone and tretinoin, and all of patients received sunblock. Most frequent time interval was two weeks (30.8%). The most common side effect was erythema (10 out of 22). Decreased MASI score was discovered in 48.1% and the most decreased category was mild (14 out of 25). Conclusions: The very common topical drugs used are hydroquinone and tretinoin. The side effect of the treatment is Erythema. The decreased MASI score is mild. [AMJ.2016;3(4):610–5]DOI: 10.15850/amj.v3n4.947

Abstract

Indonesia merupakan negara yang mengalami kenaikan kejadian obesitas, hipertensi dan diabetes setiap tahunnya. Keadaan ini membuat meningkatnya prevalensi sindrom metabolik. Sindrom metabolik adalah kombinasi dari sejumlah kondisi, yaitu hipertensi, hiperglikemia, hiperkolesterolemia, hipertrigliserida dan peningkatan ukuran lingkar perut. Asupan energi dan pola makan yang berlebihan, peningkatan kejadian obesitas, aktivitas fisik sedentari dan riwayat risiko penyakit menjadi faktor resiko sejumlah kondisi penyebab terjadinya sindom metabolik. Kabupaten Pangandaran merupakan salah satu daerah pesisir pantai di Provinsi Jawa Barat yang secara demografis dimungkinkan tingginya konsumsi garam yang dapat memicu hipertensi. Pola makan dan aktivitas fisik yang tidak baik bagi kesehatan serta rendahnya tingkat pengetahuan dan kesadaran tentang bahaya sindrom metabolik memengaruhi jumlah kejadian sindrom metabolik. Pengabdian masyarakat ini dilakukan sebagai upaya preventif melalui pengisian kuisioner untuk mengetahui pola makan dan aktivitas fisik masyarakat kecamatan Cijulang Kabupaten Pangandaran serta pengukuran lingkar perut untuk mengetahui prevalensi resiko terjadinya sindrom metabolik. Dari 544 responden rata-rata berusia 30 tahun, 129 orang mempunyai lingkar perut yang tidak normal, 47% mengkonsumsi manis setiap hari 32% mengkonsumsi asin setiap hari dan 56% tidak olahraga setiap hari.
