By DOROTHEA ZUCKER-FRANKLIN, EDWARD C. FRANKLIN AND NORMAN S. COOPER T HE ROLE of the plasma cell in the synthesis of y-globulin has been readily accepted because of the excellent correlation found between the number of plasma cells in tissues, the ability to form antibodies, and the level of y-globulin in the serum. Thus, there is a lack of plasma cells in agammaglobulinemia, an increase in pl...

The net synthesis of low density plasma lipoproteins has been shown in the perfused rat liver and in rat liver slices in work reported from this laboratory (2). Haft, Roheim, White, and Eder (3) demonstrated amino acid incorporation into low and high density plasma lipoproteins in the perfused liver, and Radding and Steinberg (4) reported similar observations in rat liver slices. The present ex...

BACKGROUND: Zinc (Zn) is one of the most important essential elements in the body of animals and plants. Zinc plays a significant role in the structure of more than 300 different proteins and in many life supporting biochemical and metabolic processes such as cellular respiration and protection against free radicals. Nanoparticles of zinc are the new form of Zinc used in cosmetic and personal c...

Objective: Achillea millefolium (A. millefolium) is known as an orexigenic herb in Iranian traditional medicine. In this study, the possible orexigenic effect of hydro-alcoholic extract of A. millefolium was investigated by measuring plasma ghrelin level.Materials and Methods: Thirty male Wistar rats were divided into five groups. Control group received water. Treatment groups received 50, 100 ...

A selective and sensitive liquid chromatography-tandem mass spectrometry (LC-MS/MS) method was developed for the determination of berberine, palmatine and jatrorrhizine in rat plasma. Target compounds, together with the internal standard (metronidazole), were extracted from rat plasma samples by protein precipitation with acetonitrile-methanol (1:2, v/v). Chromatography was carried out using a ...

Background: S-methyl cysteine (SMC) is a hydrophilic cysteine-containing compound naturally found in garlic and onion. The purpose of the present study was to investigate the protective effect of SMC on oxidative stress, inflammation and insulin resistance in an experiment of metabolic syndrome.Methods: Male Wistar rats were divided into five groups (6 rats in each group), namely; control, cont...

Objective(s):Consumption of high-fat foods is one of the major causes of obesity. Physical exercise is a strategy used to counteract obesity. The aim of this study was to investigate the effect of eight weeks endurance training and high-fat diet (HFD) on appetite-regulating hormones in rat plasma. Materials and Methods:Twenty eight male Wistar rats were randomly divided into four groups: Contro...

PURPOSE To develop a stereoselective high performance liquid chromatographic assay for determination of desbutylhalofantrine (DHF) enantiomers in rat plasma. METHODS After protein precipitation of 100 microL of rat plasma, racemic DHF and internal standard (quinidine sulfate) were extracted into hexane in the presence of pH 8 phosphate buffer. After transfer and evaporation of the hexane, the...

1. A rapid method for the isolation of hormonally sensitive rat fat-cell plasma membranes was developed by using immunological techniques. 2. Rabbit anti-(rat erythrocyte) sera were raised and shown to cross-react with isolated rat fat-cells. 3. Isolated rat fat-cells were coated with rabbit anti-(rat erythrocyte) antibodies, homogenized and the homogenate made to react with an immunoadsorbent ...
