“…To date, investigations of the biosynthesis of CaOx crystals in plants have been very limited. In vitro, CaOx crystals can be spontaneously synthesized via reactions consisting of aqueous Ca 2+ with the spinach lixivium, which contains oxalic acid (Li et al, 2010). Therefore, the Ca 2+ and oxalic acid levels influence CaOx crystal deposition (Cheng et al, 2018; Franceschi & Nakata, 2005; He et al, 2014).…”

In Nicotiana tabacum, the degeneration of connective tissue and stomium tissue (the stomium and circular cell cluster [CCC]) is essential for anther dehiscence. Both connective cells and CCC cells are crystal idioblasts, and these cells will undergo degeneration after accumulating calcium oxalate (CaOx) crystals. However, detailed data concerning this process are minimal. Therefore, this study used cellular biological and physiological methods to illustrate this relationship. Results demonstrated that tobacco anther dehiscence is a series of timed programmed cell death (PCD) processes that include the CCC, connective tissue, and stomium. The degenerating crystal idioblasts of the tobacco anther were found to possess two hallmark characteristics that distinguished them from normal PCD cells, namely dynamic changes in CaOx crystals and the appearance of numerous peroxisomes. The accumulation of CaOx and the production of H2O2 occurred simultaneously or successively before PCD. The peak H2O2 content was found to appear after the insoluble oxalate. Further, CeCl3 cytochemistry staining was used to detect subcellular H2O2, and the precipitate of H2O2 was primarily present in peroxisomes and around CaOx crystals. These results show that anther dehiscence in N. tabacum is a PCD process in which crystal idioblasts play a vital role in CaOx degradation and H2O2 production.

“…Hyperkalemia (high K level in blood) is a condition in which the blood potassium concentration is more than normal (for rat is 3.6-6 mEq/L). According to (22) and (8), hyperkalemia occurs when the kidneys are unable to excrete K properly. The most common cause of hyperkalemia is the use of substances (drugs or food) that block the kidney's disposal of K. According to (23), damaged kidneys with a decreased glomerular filtration rate are unable to excrete cellular K into body fluids, causing hyperkalemia.…”

A field experiment Porang (Amorphophallus mueleri Blume) has the potential to be developed as a functional food ingredient because it contains high levels of glucomannan. Research on the acute toxicity test of macerated porang flour has been carried out. The results of research showed a toxic effect which was characterized by high SGOT and sodium levels. The purpose of this study was to find out the safety level of consuming porang flour with lowered calcium oxalate content. This research was an experimental study designed in one directional-pattern Completely Randomized Design using 5 treatments of porang flour administration with doses of 0; 5; 50; 500; 5000 and 15000 mg/kgbw and 6 repetitions for 60 days using Wistar-strain white rats (Rattus norvegicus) as laboratory animals. The results showed that during the treatment, the administration up to a dose of 500 mg/kgbw did not give a significant difference to all observed variables. The administration of 5000 and 15000 mg/kgbw gave a significant difference on the changes in body weight, the addition of the amount of water drunk, the levels of Calcium, Potassium and Sodium in the blood, SGOT and SGPT values, and observation on necrotic cells in the kidneys. The administration of the highest porang flour dosage, namely 15000 mg/kgbw did not cause any rat mortality and did not cause any real cell damage to the liver, but caused hyperactive behavior in female rats.
