Incorporation of secondary autoxidation products (SP) of linoleic acid into the rat body was investigated. Radioactive SP was administered orally to a group of 5 rats, and excretions of radioactive substances in feces, urine and respiration were measured and compared with excretions from rats fed linoleic acid and its hydroperoxides. The SP-fed group excreted 45% and the other groups about 10% of the administered radioactivity through feces. Urinary excretion accounted for 52% of activity ingested in the SP group and less than 30% in the other groups. The 14CO2 produced in each group was about 25% of the ingested activity. Incorporation of the radioactive substances of SP into tissues and organs was measured periodically after administration of a single dose. The radioactive substances accumulated in the liver between 12-24 hr after administration and accounted for 2.6% of the total amount given, the highest level of all tissues and organs. This accumulation led to an elevation of serum transaminase activities, an increase in hepatic lipid peroxide, as determined by thiobarbituric acid test, and a slight hypertrophy of liver (1.5-fold). Therefore, absorbed SP appeared to contribute to the deleterious condition of the liver.
Because children cannot be expected to take medications correctly by themselves, parents are responsible for administering drugs based on the information provided by pharmacists. It has been reported that 90% of children aged 3 5 years in Japan attend kindergarten or nursery school, where teachers are responsible for the administration of some drugs to children. This study evaluated the types of information that teachers receive from parents. We conducted a questionnaire-based survey on drug information imparted to 144 teachers working in kindergarten or nursery schools in Hiroshima and Kure. The teachers reported that drug information from parents mainly comprised dosage and usage. However, little information was provided concerning the drug name, adverse drug reactions, and interaction with food items. To administer drugs to children safely, kindergarten and nursery teachers considered the information regarding adverse drug reactions (111/123 teachers), interaction with foods (106/123 teachers), and eŠective means of administering drugs (117/123 teachers) as important. The pharmacists' prescription notes have information on dosage, usage, drug name, adverse drug reactions, and interaction with food items. However, the teachers receive drug information from parents in the order of oral communication, a written note, and via the pharmacists' prescription note. Seventy-two percent of teachers (89/123 teachers) insisted on needing the pharmacists' prescription note. These results suggest that teachers are uncomfortable administering medications to children primarily due to inadequate information. Pharmacists should instruct parents to provide teachers with prescription notes to prevent grave medication errors.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
