Lipid and lipoprotein levels in adults receiving Liposyn II.

Lipid and lipoprotein levels were measured in 45 adult patients receiving parenteral nutrition for 10-14 days who were administered 20-50% of their daily total calorie requirement as Liposyn II. The study was an unblinded noncomparative multicenter investigation. Measurements were made on days 1, 3, 7, 10, and 14.

Biochemical, endocrine, and mineral effects of indapamide in black women.

Black women with established essential hypertension, without renal insufficiency or diabetes mellitus, were withdrawn from their usual antihypertensive therapy for 2-3 weeks prior to entry into a study to evaluate pertinent biochemical and mineral effects of indapamide treatment. Twenty patients with a sitting diastolic blood pressure greater than 90 mm Hg had baseline measurements of plasma total cholesterol, HDL cholesterol, triglycerides, glucose, uric acid, potassium, magnesium, calcium, selenium, renin, norepinephrine, whole blood ionized calcium, and glycosylated hemoglobin. Low-density lipoprotein (LDL) cholesterol was calculated by the Friedewald equation.

In vitro assay of pancreatic acinar-cell function of rats made chronically riboflavin deficient.

To determine the effect of riboflavin deficiency on the rat pancreas, one-third of a group of rats was fed a purified riboflavin-sufficient diet ad libitum and two-thirds were fed isocaloric amounts of riboflavin-deficient diet for 13 wk; one-half of the latter group was replenished with daily intraperitoneal injections of riboflavin for the last 3 wk. Body weight, pancreas weight, DNA, protein, amylase, chymotrypsinogen, and trypsinogen decreased in riboflavin-deficient animals. In vitro basal secretion of chymotrypsinogen decreased and basal and bethanechol-stimulated secretions of trypsinogen increased in riboflavin-deficient rats.

Water-soluble vitamins in cancer patients on parenteral nutrition: a prospective study.

Forty-three patients with mild weight loss were studied prospectively to determine whether the parenteral water-soluble vitamin doses in a commercially available preparation (MVI concentrate; USV Laboratories, Tarrytown, NY) maintained serum, red blood cell (RBC), and urinary concentrations of water-soluble vitamins in stressed cancer patients receiving total parenteral nutrition (TPN). Patients were divided into three groups: (1) oral diet, no intravenous vitamins given; (2) TPN plus 5 ml MVI; and (3) TPN plus 10 ml MVI. Vitamins C, B1, B2, B3, B6, and niacin were measured initially and weekly during a 6-week study period.

Nutrient retention in preterm infants fed standard infant formulas.

Our purpose was to compare nitrogen, mineral, and zinc balance in preterm infants fed standard infant formulas, Similac With Iron and Similac With Whey + Iron. Nitrogen and magnesium balances were similar during both feeds, and met estimated fetal requirements. Infants absorbed and retained (milligrams per kilogram per day) more calcium, phosphorus, and zinc when fed Similac With Iron.
