(1) Plasma renin activities (PRA) and aldosterone concentrations increased in parallel over a wide range of plasma volume deficits produced in unanesthetized rats by extravascular administration of polyethylene glycol (PEG) solution.
(2) To determine whether long-term enteral feedings can improve nutritional status and lung function parameters in patients with cystic fibrosis (CF), 11 patients (8 female, 3 male, age 7 to 23 years) received a percutaneous endoscopic gastrostomy (PEG) since February 1988.
(3) Advisable in a first time for the feeding of patients with palliative treatment, we propose PEG for patients in position to have a long and difficult rehabilitation of swallowing.
(4) Metoprolol was introduced into the stomach with a homogenized meal containing a nonabsorbable marker, [14C]-PEG 4000, and another marker, PEG 4000, was perfused continuously into the duodenum just below the pylorus.
(5) Decreased consistency of the stools was seen after PEG in both groups (p < 0.001).
(6) Since PEG-1000 treatment of HPRT- Chinese hamster cells in the absence of human cells yielded no HPRT+ cells, it is concluded that the element responsible for the restoration of rodent HPRT was contributed by the human cells and not by the agent employed to promote fusion.
(7) The CD spectra of these aggregates showed psi-type anomalies and intensities 10-100 times greater than those obtained with the dispersed DNA solutions in the absence of PEG.
(8) We next tried to prepare virus-free PEG-PLP-Hb from HBV or HTLV-I positive blood.
(9) The yes camp should have made no bones about a call to the nation to shake things up, by bringing him down a peg or two.
(10) The fast process in the presence of PEG was identified as due to rapid interbilayer monomer diffusion between closely apposed vesicles, and, in the absence of PEG, as due to monomer diffusion through the aqueous phase.
(11) Since it was first described Percutaneous Endoscopic Gastrostomy (PEG) has rapidly become the preferred method for gastrostomy tube placement.
(12) Percutaneous endoscopic gastrostomy (PEG) has become a commonly performed procedure to provide nutritional support to chronically ill patients.
(13) CIC-PEG and TRAb levels were similar in newly diagnosed and relapsed patients, being higher than in controls (p less than 0.01) and in remission patients (p less than 0.01).
(14) At a second operation, 10 days later, these adhesions were graded and lysed, after which the animals received one of the following solutions intraperitoneally: 5 per cent PEG 4000 (n = 21), 25 per cent PEG 4000 (n = 23), 32 per cent dextran 70 (n = 22) or isotonic saline (n = 25), or were left as an untreated control group (n = 20).
(15) The main histological features of the tumour were enormous, but relatively regular, acanthosis of rete pegs revealing no similarity to the squamous-cell carcinoma, and an exclusively parakeratottic eleidine-containing central plug.
(16) One hundred thirty-six percutaneous endoscopic gastrostomies (PEGs) were placed in 126 patients with head and neck malignancies.
(17) Sera from patients (n = 24) with hemolytic transfusion reactions and no detectable antibody by routine technics were tested; two sera had specific antibodies by the PEG technic.
(18) The PEG derivatization of enzymes with this procedure is less inactivating than those previously reported.
(19) Both liposome-mediated delivery and PEG conjugation offer an additional benefit over native superoxide dismutase and catalase because they can increase cellular antioxidant activities in a manner that can provide protection from both intracellular and extracellular superoxide and hydrogen peroxide.
(20) Both from diagnostic and prognostic points of view, PEG is of less value is communicating hydrocephalus on account of the many false findings.
