Accumulation of Calcium Crystal in Rat (Rattus norvegicus) Kidney

The aim of the research was to know the effect of tuber Porang powder (Amorphophallus muelleri) toward the accumulation of calcium crystal. The research used 2,5-months-old male rats that wer orally given tuber Porang powder from three different locations (Klangon, Sumber Baru, and Sumber Bendo) with doses of 6 mg/100 gr BW/day for 3 months. Kidneys were taken to be analyzed in terms of distribution of calcium crystal accumulation. The distribution of calsium crystal accumulation was observed under an Olympus microscope CX 31 at 400x magnification. The data were analysed using ANOVA employing SPSS 16 for Windows. The result of the study showed that consumption of tuber Porang powder induced calcium crystal accumulation in rat kidneys. The use of tuber Porang powder from different locations was found to generate different impacts on the accumulation of calcium crystal. The lowest calcium crystal accumulation in kidneys was the ones given Klangon Porang powder, which was equal to 8,19±2,17 spot/ area. In short, the consumption of tuber Porang powder caused the accumulation of crystal calcium in rat kidneys.
