Acute toxicity of drugs in newborn animals
The Journal of Pediatrics, 1966The acute toxicities of 30 compounds were compared in 1- to 3-day-old and adult(150 gram) rats. The effect of maturation on acute toxicity was generally consistent within a pharmacologic class of compounds. Only 16 of the 30 compounds were particularly more toxic to the newborn rat. The central nervous system depressants were more toxic in the immature

Acquired tolerance of foreign cells in newborn animals
Proceedings of the Royal Society of London. Series B - Biological Sciences, 1956Acquired tolerance of skin homografts may be brought about experimentally by the introduction of the antigenic stimulus, in the form of living homologous tissue cells, into the embryo before its immunological defence mechanism has become functionally mature (Billingham, Brent & Medawar 1953, 1956). In practice, this may be accomplished

Intestinal Absorption of Colostral Lymphoid Cells in Newborn Animals
Advances in Experimental Medicine and Biology, 2002Intestinal absorption of colostral lymphoid cells was studied in 23 piglets of four sows and 17 lambs of ewes. From the colostrum and blood of the dams the lymphoid cells were isolated with Ficoll-Paque and labelled with technetium (Na99mTcO4). In the 7th hour after birth, 10 ml volume of the cell suspensions (piglets: 10(7) cells, lambs: 5 x 10(7 ...

Myocardial function in the newborn animal
The Journal of Pediatrics, 1964The roles of hypoxia and hypercapnia in elevating pulmonary arterial pressure and resistance were evaluated in normal unanesthetized newborn lambs. Nineteen Iambs without ductus shunting were studied in room air 4 hours to 10 days after birth with blood gases, pH, pulmonary, systemic, and atrial pressures, and indicator dilution cardiac output ...

THE EFFECT OF HYPOXIA ON NEWBORN ANIMALS, WITH REFERENCE TO HYALINE MEMBRANE DISEASE.
Pediatrics, 1963Various lines of clinical evidence point to an association between perinatal hypoxia and the genesis of hyaline membrane disease in human infants. The question of whether hyaline membranes can be caused by hypoxia alone was investigated in experimental ...

Chest compressions in newborn animal models: A review
Resuscitation, 2015Much of the knowledge about the optimal way to perform chest compressions (CC) in newborn infants is derived from animal studies. The objective of this review was to identify studies of CC in newborn term animal models and review the evidence. We also provide an overview of the different models.MEDLINE, EMBASE and CINAHL, until September 29th 2014 ...

Diazepam metabolism and anticonvulsant activity in newborn animals
Biochemical Pharmacology, 1973Abstract Diazepam metabolism was studied in vivo and in vitro in newborn and adult rats and guinea-pigs. Both newborn rats and guinea-pigs are more sensitive to the antimetrazol action of diazepam than the adult animals. The difference in activity was about fifteen times for rats but only twice for guinea-pigs.

PASTEURELLA MULTOCIDA MENINGITIS IN NEWBORNS AFTER INCIDENTAL ANIMAL EXPOSURE
Pediatric Infectious Disease Journal, 2009We present briefly 2 newborns with Pasteurella multocida meningitis following incidental household exposure to domestic pets and review 36 additional cases from the literature. Of 38 reported cases of P. multocida meningitis during infancy, 18 were less than or equal to 1 month of age.

Digoxin Dosage in Newborn Animals and Infants
Pediatrics, 1962Please do not think that, after our recent letter in Pediatrics (29:500, 1962), we wish to monopolize the column of Letters to the Editor. However, the paper by Levine and Blumenthal on "Digoxin Dosage in Premature Infants" (29:18, 1962) touched us so heartily that we must write of our experiences.

A digital readout vibrational activity monitor for newborn animals
Physiology & Behavior, 1977Abstract We describe a device to monitor activity in the preambulatory neonatal rat. It can be readily accommodated to larger animals as well. It consists of (1) an inexpensive mechanical-to-electrical transducer, (2) a pulse height analyzer, limiter, and one-shot multivibrator, and (3) a digital electronic counter with LED display.
