Summary
Aloe vera extracts showed no toxicity to corneal cells. Ethanol and ethyl acetate extracts may be beneficial for treating eye inflammations and external eye conditions.
Area of Science:
- Ophthalmology
- Pharmacology
- Cell Biology
Background:
- Ocular diseases present a significant health challenge, necessitating novel therapeutic strategies.
- Medicinal plants, such as Aloe vera, offer potential treatments due to their known healing properties.
Purpose of the Study:
- To investigate the in vitro effects of Aloe vera extracts on human corneal cells.
- To evaluate the impact of different solvent extracts on cellular responses.
Main Methods:
- Assessed toxicity, proliferation, reactive oxygen species (ROS), nitric oxide (NO), and cytokine production.
- Utilized techniques including MTT, DPPH, Griess reaction, and ELISA.
- Analyzed F-actin distribution using rhodamine-phalloidin staining.
Main Results:
- Aloe vera extracts (ethanol, ethyl acetate, heptane) exhibited no toxicity to human corneal cells.
- Ethyl acetate extract demonstrated significant free radical scavenging activity.
- All tested extracts reduced nitric oxide (NO) and pro-inflammatory cytokine (IL-1β, IL-6, TNF-α) production.
Conclusions:
- Aloe vera contains active compounds that modulate cellular functions relevant to ocular health.
- Ethanol and ethyl acetate Aloe vera extracts show promise for use in eye drops to manage corneal inflammation and related conditions.
