"This article describes and analyzes the activities and impact of the Seikatsu Club movement in Japan, a social and political movement of Japanese women. Based on our analysis, we attempt to demonstrate the following conclusions: 1. The Seikatsu movement has been remarkable as a vehicle for recruiting and mobilizing women locally both in community activities and electoral politics. 2. For many women, participating in the public, political sphere is transformational and for a smaller minority, values and goals have been redefined and they have gained a new sense of empowerment. For the latter group of 'New Women', greater gender consciousness appears to be developing. 3. While the movement's goals and those of many individuals within it are challenging to prevailing Japanese politics and economics, there are contradictions. Organizationally, hierarchy and paternalistic male leadership have been dominant, despite the formally democratic structure. And aspects of the movement's ideology (e.g. linkage to domestic producers, non-professional housewives seeking electoral office) are profoundly conservative. 4. The movement has demonstrated considerable success at the ballot box in local areas in recent years, although its geographic scope and numerical depth remains limited. Still, it is among the few non-party groups of independents to attain increased representation at the local level. However, commitment to electoral rotation and income sharing may limit the growth of female professional politicians arising from the Seikatsu movement. 5. Seikatsu-elected proxies have achieved incremental policy impact on a number of issues at the local level and movement groups have become active as service providers and policy implementers as well through new administrative partnerships with sympathetic mayors and bureaucrats."

"Background: Nigella sativa (NS) seed extract shows diuretic activity, inhibits sympathetic nervous system overactivity and increases the production of Nitric Oxide in in vivo studies, thus it has a potential use as an adjuvant antihypertensive for elderly population. This study aimed to determine the effect of Nigella sativa seed extract to systolic blood pressure (SBP) and diastolic blood pressure (DBP) of elderly patients with hypertension. Methods: a double-blind, randomized controlled trial was conducted on elderly subjects with hypertension in three outpatient clinics in Cipto Mangunkusumo National Hospital Jakarta Indonesia from June to September 2011. Subjects were divided into intervention group given 300 mg Nigella sativa seed extract twice daily for 28 days and into another group which was given placebo. Blood pressure were measured on day 1 and 28. Intention o treat analysis using unpaired t-test to compare blood pressure after intervention between the two groups was performed. Results: of a total of 85 patients, 76 subjects fulfilled the study criteria and were randomized into 2 groups, with 38 subjects in each group. Both groups were comparable in all important prognostic factors. The mean systolic blood pressure of the NS group was decreased from 160.4 (SD 15.7) mmHg to 145.8 (SD 19.8) mmHg, and from 160.9 (16.3) mmHg to 147.53 (SD 22.0) mmHg in the placebo group (p=0.36). The mean diastolic blood pressure in the NS group was decreased from 78.3 (SD 11.9) to 74.4 (SD 8.2) mmHg, and from 79.0 (SD 12.4) to 78.2 (SD 8.9) in the placebo group (p=0.35). Reported adverse events include dyspepsia in 6 subjects (15.7%), nausea in 3 subjects (7.8%), and constipation in 2 subjects (5.2%). No electrolyte abnormalities, liver and renal toxicities, or orthostatic hypotension were observed. Conclusion: although a trend towards a slight decrease in blood pressure was observed, Nigella sativa has not been proven to be effective in reducing blood pressure in elderly patients with hypertension.

Latar belakang: ekstrak biji Nigella sativa (NS) pada penelitian in vivo menunjukkan potensi sebagai anti hipertensi karena memiliki efek diuretik, meningkatkan produksi Oksida Nitrit dan menghambat overaktivitas sistem saraf simpatis, sehingga potensial digunakan sebagai obat anti hipertensi pada pasien usia lanjut. Penelitian ini bertujuan untuk mengetahui pengaruh pemberian ekstrak biji NS pada perubahan tekanan darah sistolik (TDS) dan tekanan darah diastolik (TDD) pasien usia lanjut dengan hipertensi.

Metode: dilakukan uji klinis acak tersamar ganda mulai Juni hingga September 2011 terhadap 76 pasien usia lanjut dengan hipertensi di tiga poliklinik di RS Cipto Mangunkusumo Jakarta Indonesia. Dengan alokasi tersamar, subyek dibagi menjadi kelompok yang mendapat kapsul berisi ekstrak biji NS 300 mg sebanyak 2 kali sehari selama 28 hari dan kelompok yang mendapat plasebo. Tekanan darah (TD) diukur pada hari ke-1 dan ke-28. Dilakukan analisis dengan uji-t tidak berpasangan untuk melihat perbedaan tekanan darah pada kedua kelompok setelah intervensi dengan prinsip analisis intention to treat. Hasil: dari 85 subjek yang memenuhi kriteria awal, didapatkan 76 subjek yang sesuai kriteria penelitian dan dirandomisasi menjadi dua kelompok, masing-masing terdiri dari 38 subjek. Pada akhir pengamatan, TDS kelompok NS turun dari 160,4 (SD 15,7) menjadi 145,8 (SD 19,8) mmHg and pada plasebo turun dari 160,9 (SD 16,3) menjadi 147,53 (SD 22,0) mmHg (p=0,36). TDD pada kelompok NS turun dari 78,3 (SD 11,9) menjadi 74,4 (SD 8,2) dan pada kelompok plasebo turun dari 79,0 (SD 12,4) menjadi 78,2 (SD 8,9) mmHg. Efek simpang yang dilaporkan adalah dispepsia pada 6 subjek (15,7%), mual pada 3 subjek (7,8%) dan konstipasi pada 2 subjek (5,2%). Tidak didapatkan gangguan elektrolit, gangguan fungsi ginjal, hati, maupun hipotensi ortostatik. Kesimpulan: meskipun menunjukkan kecenderungan penurunan tekanan darah, Nigella sativa belum terbukti dapat menurunkan tekanan darah pasien usia lanjut dengan hipertensi"

"ABSTRAKPendahuluan: Hipoksia adalah kondisi dimana jaringan tubuh mengalami kekurangan oksigen. Hal ini dapat memicu pembentukan radikal bebas dan menyebabkan kerusakan jaringan. Antioksidan, contohnya enzim katalase diketahui memiliki kemampuan untuk menanggulangi radikal bebas. Enzim katalase berperan untuk mengubah hidrogen peroksida menjadi air dan oksigen. Penelitian ini bertujuan untuk mempelajari aktivitas spesifik enzim katalase pada jaringan otak tikus yang mengalami hipoksia sistemik berkelanjutan. Metodologi: Penelitian ini menggunakan 15 ekor tikus yang dibagi menjadi 5 kelompok, yaitu kontrol dan 4 kelompok perlakuan yang dipaparkan pada kondisi hipoksia sistemik selama 1, 3, 5, dan 7 hari. Aktivitas spesifik katalase pada jaringan otak tikus kemudian diukur menggunakan spektorofotometer. Data dianalisis secara statistik dengan uji one way ANOVA. Hasil: Hasil menunjukkan bahwa aktivitas spesifik katalase menurun pada 3 hari pertama secara bertahap dan meningkat secara bertahap pula pada hari selanjutnya, ke 5 dan 7. Akan tetapi tidak ditemukan perbedaan yang bermakna (p > 0.05, p= 0.293) diantara semua kelompok. Kesimpulan: aktivitas spesifik katalase jaringan otak pada penelitian ini tidak menunjukkan perubahan secara signifikan pada keadaan hipoksia sistemik berkelanjutkan.

ABSTRACTIntroduction: Hypoxia is a condition of deprivation oxygen supply to the tissue. This condition leads to the formation of free radical and further lead to the tissue damage. Antioxidant, such as catalase enzyme, was known for its ability counter the free radical. Catalase enzyme works by converting hydrogen peroxide into water and oxygen. The aim of this study is to observe the specific activity of catalase enzyme in brain tissue of rats exposed to continuous systemic hypoxia. Methods: This study used 15 rats that was divided into 5 groups: the control, and 4 experimental groups that were exposed with hypoxia for 1, 3, 5, and 7 days. The specific activity of catalase in brain tissue was then measured with spectrophotometer. The data were statistically analyzed by one way ANOVA test. Result: A steady decreased of specific activity of catalase in the first 3 days of exposure and then increase in the 5th and 7th days.. There were no significance differences between all groups (p>0.05, p=0.293 ). Conclusion: It is concluded that the specific activity of catalase in brain tissue of rats showed no significant changes during continuous systemic hypoxia."
