New method for obtaining IgA-specific protease.
A simple method for obtaining an active preparation of IgA-specific protease from a bacterial source is presented. In this method Streptococcus sanguis was inoculated onto the surface of a dialysis membrane on nutrient agar. Following growth, the membrane was removed from the agar surface and washed in a small volume of buffer. A solution with protease activity against IgA1 monoclonal proteins was obtained by clarification of the wash and appeared to be similar to enzyme preparations obtained by other methods.

Ozone and vitamin E.
Vitamin E deficiency in rats is associated with a greater susceptibility to lethal levels of ozone. Exposure of rats to sublethal ozone concentrations produces an accelerated decline in serum vitamin E levels. These findings are consistent with the possibility that lipid peroxidation is a mechanism of ozone toxicity.

Long-term outcome of neonatal macular hemorrhage.
BACKGROUND: We studied long-term visual acuity in children who had macular hemorrhages at birth. METHODS: Of 11 involved children, seven had eye examinations at about age 10. Two were contacted by telephone; two were lost to follow up. RESULTS: Of the seven examined children, six had normal visual acuities. One had reduced vision in the eye with the macular hemorrhage, possibly related to deprivation amblyopia secondary to slow resorption of the hemorrhage. The two patients contacted by telephone reported normal vision. CONCLUSION: Although macular hemorrhages generally resolve without any lasting damage, the outcome may be less favorable in some patients.
