Soemarsono - Penurunan tekanan bola mata dengan 6=101
Glaukom merupakan salah satu dari lima penyebab utama kebutaan di Indonesia. Timolol merupaltan obat glaukom yang belum lama dipergunakan di Yogyakarta. Timolol tergolong betablocker yang dapat menurunkan tekanan bola mata dengan cara menghambat produksi humor aquosa pada corpus ciliare.
Telah dilakukan percobaan pada orang normal kelompok muda berumur antara 10-20 tahun, kelompok normal lanjut usia berumur 40 60 tahun, clan kelompok penderita glaukom primer. Pada ketiga kelompok tersebut diberi tetesan maleat timolol 0,5%. Terjadi penurunan tekanan bola mata yang jelas setelah satu jam. Dua jam setelah tetesan masih terjadi penurunan tekanan bola mata yang nyata pada kelompok normal muda usia dan kelompok penderita glaukom primer. Dengan perhitungan statistik penurunan tersebut ternyata bermakna.

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Aktivitas isosim glucose-6-phosphate dehydrogenase (G6PD) pada penderita glaukoma simpleks
Get PDFABSTRACT
Simple glaucomas are charaterized by an elevated intra ocular pressure (10P) and, are an important cause of blindness in the world. The blindness is due to the optic nerve atrophy and is found more frequently in women. It has been reported that high activity of G6PD isozyme can reduce the ocular pressure in the calf eyes. The activity of G6PD isozyme in the blood of simple glaucoma patients has been examined, and compared to those of normal persons. This study consisted of 76 patients of simple glaucoma (41 men and 35 women) and 30 normal persons as a control group. The 10P of both patients and control group was measured by using a Schiotz tonometer. The average of the G6PD isozyme activity was 9.40 ulg Hb in the simple glaucoma and 10.94 u/g Hb in control group. The two G6PD isozyme activity showed a significant difference. It can be concluded that the activity of G6PD isozyme of simple glaucoma patients were lower than those of normal persons without glaucoma symptoms.

Soemarsono - Aktivitas isosim glucose-6-phosphate dehidrogenase (G6PD) pada penderita glaukoma simpleks
Glaukoma simpleks yang ditandai oleh peningkatan tekanan intraokular merupakan salah satu penyebab kebutaan. Kebutaan terjadi oleh karena atrofi nervus opticus dan ditemukan lebih sering pada wanita. Telah dilaporkan bahwa tingginya aktivitas isosim glucose-6-phosphat dehydrogenase (G6PD) dapat menurunkan tekanan okular di dalam rongga mata. Aktivitas isosim G6PD dalam darah pada pasien dengan glaukoma simpleks telah diteliti dan dibandingkan dengan individu normal. Penelitian ini melibatkan 76 penderita glaukoma simpleks (41 laki-laki dan 35 wanita) serta 30 individu normal sebagai kelompok pembanding. Tekanan intraokular seluruh subjek baik penderita maupun kelompok pembanding diukur dengan tonometer Schiotz. Aktivitas isosim G6PD adalah 9,4 u/g Hb pada penderita glaukoma simpleks dan 10,4 ulg Hb pada kelompok pembanding. Perbedaan aktivitas kedua isosim G6PD bermakna. Kesimpulan, aktivitas isosim G6PD pada penderita glaukoma simpleks lebih rendah daripada individu normal yang tidak memiliki gejala-gejala glaukoma
