Oral Sucrose Versus Breastfeeding in Managing Infants' Immunization-Related Pain: A Randomized Controlled Trial.

Background: Treating pain during immunization should be a part of pediatric primary healthcare around the world, as untreated pain in children has short- and long-term consequences. Few studies of pharmacologic and nonpharmacologic methods of pain relief during immunization have been conducted in low- and middle-income countries. Finding pain-mitigating interventions that are low-cost, effective, and feasible across all settings, including with low-resourced settings could improve primary healthcare.

Chemical modification of milk xanthine oxidase with different modifiers.

Xanthine oxidase (XO), purified from buttermilk was subjected to modification with N-phenylmaleimide, p-toluene-sulfonyl chloride, and 2-mercaptobenzimidazole. Spectrophotometric monitoring of the enzyme before and after treatment with these modifiers are presented. The results show that the interaction of XO with the modifiers was accompained by a change in UV absorption, as compared with untreated enzyme.
