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.

Judul: Studi Histopatologi Potensi Radioprotektif Ekstrak Kelopak Rosela (Hibiscus sabdariffa L) terhadap Duodenum Mencit (Mus musculus) dengan Radiasi Ionisasi Radiodiagnostik Berulang
Abstrak: This study was conducted to find out the potency of Roselle (Hibiscus sabdariffa L.) as radioprotective against recurrent effect of radiodiagnostic radiation on duodenum of mice (Mus musculus). This research was to observed histophatological changes on duodenum of mice treated with roselle calyx extracts and radiation. Twenty four male mice were used in this study. They were divided into 4 groups namely control group (K) treated with 0.2 ml of NaCl 0.9 % (saline); primary radiation group (P) treated with 0.2 ml of NaCl 0.9 % (saline) and radiation 0.2 mSv; roselle group (R) treated with 0.2 ml roselle calyx extract; and primary radiation-roselle group (RP) treated with 0.2 ml roselle calyx extract and radiation 0.2 mSv. All treatments were done orally every two days for 8 weeks. Afterwards, 3 mice from each group were euthanized for organ sampling. The rest of mice were took 4 weeks of recovery. Afterwards, all mice were euthanized for organ sampling. Duodenum were fixed in Buffered Neutral Formaline (BNF) 10%, embedded in paraffin, then stained with hematoxyline and eosin (HE) and periodic-acid schiff (PAS). The result showed that RP group had lower demage of intestinal villi and numbers of goblet cell than P group. Lieberkühn crypt number of P group was increased, whereas intestinal villi height was decreased compared to R and RP groups. Roselle calyx extract (Hibiscus sabdariffa L.) showed radioprotective potency after radiation treatment on duodenum of mice.
