Abstract

Background:  Nanotechnology has the potential to produce innovations in drug formulation and drug delivery systems. Nanocosmetics and nanocosmeceuticals containing natural ingredients have been proven to overcome the weaknesses of traditional cosmetics and also add value to their formulations.Objective: This study aims to analyze the application of nanocosmeceutical technology based on ethanol extract of butterfly pea flower (Clitoria Ternatea L) in the preparation of nanoemulsion spray as a skin antiaging agent for the growth of collagen, elastin and extracellular matrix.Methods Method used true experimental design with posttest control group with random allocation to model mice given UVB radiation. The levels of collagen, elastin, and cellular matrix extract were assessed using Verhoef staining and observed by two experts,Results: The results of this research show that a nanoemulsion spray preparation of ethanol extract of butterfly pea flower (Clitoria Ternatea L) improves skin damage in aging model mice by increasing the production of extra cellular matrix, collagen and elastin. Conclusion: The preparation of butterfly pea flower flower extract nanoemulsion sprey (Clitoria Ternate L) has antiaging, collagen and elastin formation activities

Abstract

Studies in neuroscience can be performed in vitro and in vivo. In vivo studies will show significant results, but it is difficult to do and time-consuming. Primary hippocampal cell culture widely has used in neurobiological studies such as identifying the cellular mechanism of proteins, neuronal activity, and characteristics. The results of studies conducted on this cell culture will be very useful in discovering pathogenesis of a disease, the effect of a substance on the neuron, and neural basis of memory and learning. However, currently in Indonesia, primary hippocampal cell culture is still rare and difficult to do. The purpose of this study was to demonstrate that primary hippocampal cell culture can be done and developed in Indonesia and to review the application of it in medical researches. The study was an experimental study by obtaining neurons from animal’s hippocampus was conducted in 2015–2018 at Department of Cell Biology, Graduate School of Medicine Osaka University and Faculty of Medicine Universitas Padjadjaran. The experimental animal was mice embryo gathered 17.5-days postcoitus. Enzymatic and mechanical methods collected primary hippocampal cells. The cells counted and cultured, which later were observed to see neuron differentiation. The average number of culture cells from 3 embryonic’s hippocampus were 2.39×106. Neuron differentiation observed on the first day and more visible and numerous on the third day after plating. In conclusion, primary hippocampal cell culture using hippocampus from one hemisphere of embryonic mice brain showed a sufficient number of cells to carry out research and showed neuron differentiation. KULTUR SEL PRIMER HIPOKAMPUS DAN PENGGUNAANNYA DALAM RISET KEDOKTERANPenelitian dalam neurobiologi dapat dilakukan secara in vitro dan in vivo. Penelitian secara in vivo sangat berdampak hasilnya, namun sulit dan memakan waktu yang lama. Kultur sel primer hipokampus banyak digunakan dalam penelitian neurobiologi seperti melihat mekanisme protein seluler, serta aktivitas dan karakteristik neuron. Hasil penelitian yang dilakukan pada kultur sel ini akan sangat bermanfaat dalam menemukan proses suatu penyakit, efek suatu zat terhadap sel saraf, dan kemampuan belajar serta memori. Akan tetapi, saat ini di Indonesia kultur sel primer hipokampus masih jarang dan sulit dilakukan. Tujuan penelitian ini adalah menunjukkan bahwa kultur sel hipokampus primer dapat dilakukan dan dikembangkan di Indonesia, serta meninjau penerapannya dalam riset kedokteran. Penelitian ini merupakan studi eksperimental dengan mengoleksi neuron dari hipokampus hewan coba yang dilakukan pada tahun 2015–2018 di Department of Cell Biology, Graduate School of Medicine Osaka University dan Fakultas Kedokteran Universitas Padjadjaran. Hewan coba berupa embrio mencit hari ke-17,5 pascakoitus. Sel primer hipokampus dikoleksi untuk dihitung dan dikultur menggunakan metode enzimatik dan mekanik. Observasi neuron pada kultur dilanjutkan dengan mengamati diferensiasi neuron. Rerata jumlah sel kultur dari 3 hipokampus adalah 2,39×106. Diferensiasi neuron sudah tampak pada hari pertama dan makin jelas serta tampak pada hari ketiga pascapenanaman. Simpulan, kultur sel primer hipokampus menggunakan hipokampus dari salah satu sisi hemisfer otak menunjukkan jumlah sel yang cukup untuk melakukan suatu penelitian dan menunjukkan diferensiasi dari neuron.

Abstract

AbstrakMiopia merupakan kelainan refraksi yang menjadi masalah kesehatan masyarakat di dunia yang disebabkan oleh peningkatan panjang aksial bola mata sehingga cahaya tidak terfokus pada retina dan penglihatan menjadi kabur. Penggunaan gawai yang berkepanjangan dapat berkaitan dengan miopia. Kelainan refraksi di Indonesia mencapai 15% yang didoinasi anak usia sekolah dengan prevalensi 22,1%. Kelainan refraksi adalah suatu masalah yang harus diperhatikan pada anak usia sekolah yang mayoritas menggunakan gawai. Penelitian ini bertujuan menganalisis hubungan intensitas penggunaan gawai dengan kejadian miopia pada siswa SMAN 1 Cibadak Kabupaten Sukabumi selama bulan Februari 2022. Jenis penelitian ini adalah penelitian kuantitatif dengan metode observasional analitik yang disertai dengan pendekatan potong lintang. Sebanyak 92 responden didapatkan dengan metode simple random sampling. Pengambilan data dilakukan secara subjektif menggunakan kuesioner dan objektif dengan menggunakan autorefractometer dan snellen chart. Hasil dianalisis dengan Fisher's Exact test. Hasil penelitian menunjukkan sebagian besar memiliki intensitas penggunaan gawai tinggi, yaitu sebanyak 78 orang (85%) serta kejadian miopia, yaitu sebanyak 65 orang (71%). Nilai p penelitian ini didapatkan hasil sebesar 0,004. Simpulan penelitian ini terdapat hubungan antara intensitas penggunaan gawai dan kejadian miopia pada siswa SMAN 1 Cibadak Kabupaten Sukabumi.Incidence of Myopia in the Use of Gadget for Students of SMAN 1 Cibadak, Sukabumi RegencyAbstractMyopia or nearsightedness is a refractive error that is a public health problem in the world caused by an increase in the axial length of the eyeball so that light does not focus on the retina and vision becomes blurry. Prolonged use of devices can be associated with myopia. In Indonesia, 15% of school-aged children suffer from refractive errors, with a population prevalence of around 22%. This refractive error is problematic and needs to be paid attention to in school-aged children, most of whom use devices. This study aims to analyze the relationship between the intensity of device use and the incidence of myopia in students at SMAN 1 Cibadak, Sukabumi Regency, in February 2022. This type of research is quantitative, with analytical observational methods and a cross-sectional approach. A total of 92 respondents were obtained using the simple random sampling method. Data collection was carried out subjectively using a questionnaire and objectively using an autorefractometer and Snellen chart. Results of analysis using Fisher's Exact test. The research results showed that the majority had a high intensity of device use, namely 78 people (85%), and the incidence of myopia, namely 65 people (71%). The p-value of this research was 0.004. This study concludes that there is a relationship between the intensity of device use and the incidence of myopia in students at SMAN 1 Cibadak, Sukabumi Regency.
