Calcium oxalate crystal morphology
Trends in Plant Science, 2002Plants invest considerable resources of carbon and calcium in crystal formation, indicating that it is an important basic process in growth and development. The diversity of crystal shapes, as well as their prevalence and spatial distribution, have led to several hypotheses regarding crystal function in plants.

Since about 85% of synthesized calcium oxalate dihydrate (COD) crystals proved not to have changed into calcium oxalate monohydrate (COM) crystals at 30 min of incubation time at 37 °C when our evaluation method of the COD-to-COM ratio was being used, we made a comparative study of the inhibitory effects of magnesium, one of the well-known inhibitors ...

According to the theoretical expression for calibration curve as a function of the optical absorption ratio of two peaks and with the analysis of the infrared spectra of the mixture samples of commercial calcium oxalate monohydrate and synthesized calcium oxalate dihydrate, the following quadratic equation was obtained; Y = 1.79 X2 - 30.90 X + 107.04 ...

Urinary oxalate and calcium excretion by dogs and cats diagnosed with calcium oxalate urolithiasis
Veterinary Record, 2012Urine concentrations of oxalate and calcium play an important role in calcium oxalate (CaOx) urolith formation in dogs and cats, with high excretions of both substances increasing the chance of CaOx urolithiasis. In 17 CaOx-forming dogs, urine calcium:creatinine ratio (Ca:Cr) was found to be increased compared with healthy control dogs, whereas urine ...

Idiopathic Calcium Oxalate Urolithiasis
Endocrinology and Metabolism Clinics of North America, 1990Approximately 70% of patients who form metabolic stones have the idiopathic calcium oxalate urolithiasis syndrome, which is diagnosed by exclusion of other identifiable metabolic abnormalities. This article reviews the classification, risk factors, and treatment options for those patients with this syndrome.

Oxalate transport and calcium oxalate renal stone disease
Urological Research, 1996Hyperoxaluria is considered to play a crucial role in calcium oxalate (CaOx) renal stone disease. The amount of oxalate excreted into the urine depends on intestinal absorption, endogenous production, renal clearance and renal tubular transport. Since a primary disorder has not been found so far in most CaOx stone formers and since oxalate is freely ...

Calcium oxalate stone and gout
Urological Research, 2009Gout is well known to be produced by increased uric acid level in blood. The objective of this paper is to assess the relationship between gout and calcium oxalate stone formation in the humans. 48 patients with combination of gout and calcium oxalate stone problem were included.

Idiopathic Calcium Oxalate Urolithiasis and Endogenous Oxalate Production
Journal of Urology, 1996Despite the great effort that has gone into investigating urolithiasis, this condition still persists as one of the major ailments of the urinary tract. Calcium oxalate urolithiasis is the most common form, accounting for some 60 to 80% of total stones.

[Oxalate as a promoter in calcium oxalate nephrolithiasis].
Hinyokika kiyo. Acta urologica Japonica, 1992Oxalate transports on membranes of red blood cell, intestinal epithelium and proximal tubule cell were reviewed, and the new findings about oxalate transport across these membranes are reported. Red blood cell oxalate influx rate in a group of recurrent calcium oxalate stone formers was significantly higher than that of a control group.
