Purpose:
Today, the long-term effects of partial exposure of cholinesterase on the kidney continue to be a research topic. In this study, we aimed to histopathologically investigate the possible effect of acute toxicity due to fenthion, an organophosphate (OP) compound, on the kidneys.
Methods:
In all, 21 rats were randomly divided into three groups. Experimental group was each administered intraperitoneal 0.8 g/kg fenthion within physiologic serum. Sham group was only administered intraperitoneal physiologic serum. The control group continued normal nutrition with no procedure performed. After 24 h, all rats were sacrificed by cervical dislocation. Half of the recipient kidney tissues were examined histopathologically and the other half biochemically.
Results:
No histopathological findings were found in the control group. Rats in the experimental group were observed to have epithelial cell disorganization in tubules, moderate epithelial cell loss, and degeneration. Again, expansion of tubules, vacuolization of tubular epithelial cells, and tubular structure approaching atrophy were observed, with cells approaching apoptosis and common hemorrhage noted although rats in the sham group were observed to have mild tubular degeneration.
Conclusions:
It should not be forgotten that one of the causes of systemic complaints linked to acute toxicity exposed to the OP compound of fenthion may be cellular injury to glomerular and tubular structures in the kidneys.
Insights
Acute fenthion exposure, an organophosphate pesticide, causes kidney damage in rats. Histopathology revealed tubular degeneration, cell loss, and hemorrhage, indicating potential kidney injury from organophosphate toxicity.
Area of Science:
- Toxicology
- Nephrology
- Histopathology
Background:
- Organophosphate (OP) compounds are widely used pesticides.
- Cholinesterase inhibition is a known effect of OPs.
- Long-term renal effects of partial cholinesterase exposure require further investigation.
Purpose of the Study:
- To histopathologically investigate the renal effects of acute fenthion toxicity.
- To determine if fenthion exposure causes kidney damage.
Main Methods:
- 21 rats were divided into control, sham, and experimental groups.
- The experimental group received an intraperitoneal injection of fenthion.
- Kidney tissues were examined histopathologically and biochemically 24 hours post-exposure.
Main Results:
- Control group showed no renal histopathological findings.
- Fenthion-exposed rats exhibited tubular epithelial cell disorganization, loss, degeneration, and atrophy.
- Hemorrhage and apoptosis were observed in the kidneys of fenthion-treated rats, with mild degeneration in the sham group.
Conclusions:
- Acute fenthion toxicity can cause significant cellular injury to glomerular and tubular kidney structures.
- Kidney damage may contribute to systemic complaints associated with organophosphate poisoning.
- Further research is needed to understand the full spectrum of renal effects from OP exposure.

Enhanced Elimination of Poison
Antidotes serve a crucial role in counteracting the effects of poison by inhibiting enzymes responsible for producing harmful drug metabolites. In some cases, these toxic metabolites can be neutralized by endogenous cosubstrates, which are maintained at specific concentrations to prevent interaction with cellular macromolecules and subsequent cell death.
