...C.D. Hoskinson; B.P. Chew; T.S. Wong Newborn piglets were injected with either (1) vehicle; (2) 20 mg β-carotene; (3) 40 mg β-carotene; (4) 25,000 IU vitamin A palmitate, or (5) 50,000 IU vitamin A palmitate. Blood was collected at 0.5, 1, 3, and 6 weeks of age and lymphocyte proliferation...

...Indri Safititri Mukono; Masafumi Matsuo; Miyoji Komura; Hajme Nakamura The concentrations of serum retinol-binding protein (RBP), prealbumin (PA) and vitamin A of Indonesian neonates were compared with those of Japanese neonates. The mean serum concentrations of both PA and vitamin A did not differ...

...Jayant P. Shenai; Frank Chytil We examined the ontogeny of vitamin A storage in fetal and neonatal lungs during perinatal development in the rat. High-performance liquid chromatography was used to measure concentrations of vitamin A and its esters, retinyl palmitate and stearate, in various fetal...

...Jayant P. Shenai; Frank Chytil Vitamin A (retinol) is essential for normal differentiation and integrity of developing respiratory epithelium and its deficiency has been linked to an increased susceptibility to lung injury. Because significant vitamin-A storage occurs in the fetal lung near term...

...T. Koskinen; P. Valtonen; I. Lehtovaara; R. Tuimala The concentrations of retinol (vitamin A) were measured in 36 samples of human amniotic fluid obtained near term. Mothers with normal pregnancy had higher amniotic fluid retinol levels than patients with diabetes or toxemia. The results indicate...

...V.H. Ferm; R.R. Ferm Exposure of pregnant hamsters to 60–75 min of hyperthermia on the 8th day of gestation causes malformations in some of the fetuses recovered near term. The feeding of large doses of vitamin A to pregnant hamsters on the 8th day of gestation causes many of the same types...

...Michael D. Seckeler; Jennifer Linden Abetalipoproteinemia is a rare genetic condition that results in an inability of the body to absorb dietary fats, including fat-soluble vitamins. Deficiencies of these vitamins are known to cause a wide range of clinical effects ranging from blindness...

...Barbara Schmidt; Robin Roberts; David Millar; Haresh Kirpalani Corticosteroids, intramuscular vitamin A and caffeine reduce the risk of bronchopulmonary dysplasia (BPD) in very-low-birth-weight infants. We compared the size of the beneficial drug effects on BPD and evaluated long-term drug safety...
