RESUMEN
The milky sap or latex of Euphorbia plant is highly toxic and an irritant to the skin and eye. This report illustrates the spectrum of ocular inflammation caused by accidental inoculation of latex of Euphorbia plant. Three patients presented with accidental ocular exposure to the milky sap of Euphorbia species of recent onset. The initial symptoms in all cases were severe burning sensation with blurring of vision. Visual acuity reduced from 20/60 to counting fingers. Clinical findings varied from kerato-conjunctivitis, mild to severe corneal edema, epithelial defects, anterior uveitis and secondary elevated intraocular pressure. All symptoms and signs had resolved by 10-14 days with active supportive medication. People who handle Euphorbia plants should wear eye protection. It is always advisable to ask the patient to bring a sample of the plant for identification.

The objective of this study was to observe the molluscicidal activities of Euphorbia milli, known as "poysean" in Thailand, against Indoplanorbis exustus. Latex from 12 different E. milii hybrids was screened for its molluscicidal activities. Indoplanorbis exustus were exposed for 24 and 48 hours to the latex at various concentrations ranging from 6 to 25 ppm and mortality rates were recorded. Eight hybrids of latex were effective. The six most effective hybrids were E. milii Dang-udom, E. milii Arunroong, E. milii Raweechotchuong, E. milii Srisompote, E. milii Sri-umporn and E. milii Tongnopakun, which killed all snails after 24 hours of exposure. Under the same conditions, latex of E. milii Dowpraket and E. milii Promsatid killed 50% of the snails. Such results indicate that these 6 hybrids seem promising as natural molluscicidal agents.
