Judul: Studi Histopatologi Respon Organ Testis Mencit (Mus musculus) Terhadap Potensi Radioprotektif Tanaman Rosela dalam Radiasi Ionisasi Radiodiagnostik
Abstrak: The aim of this study was to determine the radioprotective effect of roselle (Hibiscus sabdariffa L.) extract in radiodiagnostic ionizing radiation on the testicle of mice (Mus musculus). Forty eight adult male of mice were used and divided into 4 groups; control (K), radiation (P), roselle without radiation (R) and roselle with radiation (RP). Mice were treated with 50 mg/kg of BW per oral of roselle extract every two days before recurrent irradiation for 8 weeks. The mice were euthanized then necropsied for testicle collection at various groups and two time points after irradiation. Samples of testicle was processed to prepare histopathology slides using Haematoxilin-Eosin stain. Parameter of the observation are numbers of spermatogenic cells, Sertoli cell, and Leydig cell after whole body irradiation counted using image J software. Quantitative data were analysed with ANOVA test and followed by Duncan post test. The number of cells observed showed a favorable response to the administration of radiation and the roselle extract. The number of cells were decreased in the primary radiation group while in the roselle were not seen. This result showed that Roselle extract was protect cells from radiation effect by recurrent radiodiagnostic ionizing radiation. Administration of roselle extract significantly reduced the bioeffects of radiation. The result suggested that roselle can be used as radioprotector to ionizing radiation on testicular organ.

Abstrak: The aim of this study was to determine the radioprotective effect of calyx Roselle (Hibiscus sabdariffa L.) extract in recurrent radiodiagnostic ionizing radiation on the gastric of mice (Mus musculus). Fourty eight adult males of mice were used and divided into 4 groups: control (K-), radiation (K+), roselle without radiation (R-) and roselle with radiation (R+). Mice were treated with 50 mg/kg of body weight orally of Roselle extract every two days prior to recurrent irradiation for 4 and 8 weeks. The mice were euthanized by overdose Ketamine and then necropsied followed gastric collection at various time points after irradiation. Sample of gastric were processed to prepare histopathology slides with Haematoxylin-Eosin stain. The changes on the gastric alterations were studied by count the amount of parietal, chief cells and infiltration of inflammatory cells after whole body irradiation. Quantitative data were analysed with ANOVA test and followed by Duncan test. Radiation during 4 week produce total radiation 2.9 mSv and 8 week produce 5.3 mSv. The result showed that Roselle extract was protect parietal and chief cells from radiation effect by recurrent radiodiagnostic ionizing radiation. Roselle extract also inhibiting inflammation process by decreasing necrosis in parietal and chief cells. Administration of Roselle extract significantly (p<0.05) reduced the bioeffects of radiation. Roselle could be useful as natural radioprotector against ionizing radiation

Abstrak: Pernikahan adalah budaya yang tidak akan pernah berhenti, pernikahan akan terjadi secara berkelanjutan Dasarnya, karena pernikahan merupakan kebutuhan biologis manusia. Indonesia adalah negara yang kaya akan budaya dan etnis. Setiap suku di Indonesia mempunyai tata cara/adat istiadat dalam pelaksanaan pernikahan itu sendiri.
