Integrated pharmacy nurse program of medication administration and intravenous therapy.

This is a descriptive report of a pharmacy nurse program involving medication administration and intravenous (IV) therapy programs that have been in continuous operation for over 15 years. Information is presented on organizational and personnel considerations for initiating and maintaining such a program. The benefits and obstacles encountered with this program are addressed. The primary reasons for an integrated pharmacy nurse program of medication administration and IV therapy are to better ensure quality of patient services in the medication distribution process from the inception of the physician's order until a patient receives a medication and to assign administrative responsibility for the entire medication process. The presence of a controlled environment with properly trained personnel is more likely to result in decreased medication errors. In this era of unprecedented medical malpractice judgements and high costs for extended lengths of stay associated with medication and IV therapy misadventures, low error rates are especially important.

Energy and nitrogen metabolism of diseased chickens: interaction of Ascaridia galli infestation and vitamin A status.

1. Effects of Ascaridia galli infection on the energy and nitrogen (N) metabolism were studied on groups of 5 cross-bred cockerels aged about 5 weeks and given a diet deficient or adequate in vitamin A at two levels of feeding in respiration chambers. 2. Metabolisability of dietary energy was 67% and N retention 33% in infected chickens compared with 71 and 41% respectively, in uninfected chickens. 3. Maintenance energy requirement of vitamin A-deficient birds was 882 kJ/kgW d compared with 998 kJ/kgW d for normal birds. N balance of the deficient chickens was also less when compared at the same energy balance. Infection did not affect maintenance energy requirement nor N balance. 4. Starvation heat production of infected chickens (619 kJ/kgW d) was higher than that of uninfected controls (586 kJ/kgW d). When infection treatments were combined, vitamin A-adequate chickens had a higher heat production (615 kJ/kg d) than the vitamin A-deficient (580 kJ/kgW d). Endogenous N excretion (mg/gW) was less in vitamin A-deficient than in adequate, starved birds. 5. Deficient chickens had undetectable liver reserves of vitamin A and only very low plasma concentrations. There was a difference in the length of larvae (17 d after infection) associated with vitamin A status, and with level of feeding.

Ciliastatic components in the gas phase of cigarette smoke.

The gas phase of cigarette smoke, separated into its components by gas chromatography, was passed across a ciliated specimen. The acetaldehyde, acrolein, and hydrogen cyanide produced strong inhibition of the ciliary beat. A filter which removed most of the acetaldehyde and acrolein from smoke did not reduce the inhibitory effect of the gas phase of that smoke, whereas a filter that removed most of the hydrogen cyanide did reduce inhibition.
