[X-ray microanalysis of Michaelis-Gutmann bodies with the use of EDAX]
Abstract:
X-ray microanalysis of Michaelis--Gutmann bodies in human malakoplakia (kidney and testes) and in that of rats induced experimentally by administration of endotoxin of Escherichia coli, was carried out. The presence of calcium could be revealed in every Michaelis--Gutmann body according to the lines of Kalfa and K3 as well. The amount of it was in correlation with the stage of the calcification. In the Michaelis--Gutmann bodies found in the rat kidney, fixed without OsO4 presence of P could also be demonstrated. The correlation between the weight per cent of Ca and P seems to evidence the presence of CaHPO4. Results of the X-ray microanalysis of Michaelis--Gutmann bodies found in human and in experimentally induced malakoplakia appeared to be similar.
Insights
X-ray microanalysis revealed calcium in Michaelis–Gutmann bodies in human and rat malakoplakia. The findings suggest calcium phosphate (CaHPO4) presence, correlating with calcification stages in this kidney and testes condition.
Area of Science:
- Pathology
- Biochemistry
- Medical Imaging
Background:
- Malakoplakia is a rare condition characterized by the presence of Michaelis–Gutmann bodies.
- These bodies are typically found in the urinary tract but can also occur in other organs like the kidney and testes.
- The exact composition and formation of Michaelis–Gutmann bodies are not fully understood.
Purpose of the Study:
- To investigate the elemental composition of Michaelis–Gutmann bodies using X-ray microanalysis.
- To compare the composition of Michaelis–Gutmann bodies in human malakoplakia with experimentally induced malakoplakia in rats.
- To explore the potential role of calcium and phosphate in the calcification process within these bodies.
Main Methods:
- X-ray microanalysis was performed on Michaelis–Gutmann bodies from human kidney and testes affected by malakoplakia.
- Experimental malakoplakia was induced in rats via endotoxin administration (Escherichia coli).
- Analysis focused on identifying elements such as calcium (Ca) and phosphorus (P) within the bodies.
Main Results:
- Calcium (Ca) was detected in all analyzed Michaelis–Gutmann bodies from both human and rat samples.
- The amount of calcium correlated with the stage of calcification observed.
- Phosphorus (P) was also detected in rat kidney Michaelis–Gutmann bodies, suggesting the presence of calcium phosphate (CaHPO4).
- The elemental composition findings were similar between human and experimentally induced rat malakoplakia.
Conclusions:
- X-ray microanalysis confirms the presence of calcium in Michaelis–Gutmann bodies.
- The data supports the hypothesis that calcium phosphate (CaHPO4) is a component, particularly in calcified stages.
- The study provides valuable insights into the composition of Michaelis–Gutmann bodies, relevant for understanding malakoplakia pathogenesis.
