the sulphated form of ascorbic acid may play a role in the maintenance of connective tissue, suggested that although 35S-labelled glycosaminoglycans are formed in the presence of ascorbic acid 2-[35S]sulphate, they are not formed by direct transfer of the sulphate moiety from ascorbic acid 2-[35S]sulphate but by a decomposition product of the ester (Shapiro & Poon, 1975). The role of ascorbic a...

Background: Eclampsia is a hypertensive disorder related to pregnancy, in which there is occurrence of one or more generalized convulsions and or coma, in the absence of other neurologic conditions. It is a common obstetric emergency. Eclampsia is associated with elevated maternal and fetal morbidity and mortality. Objectives: To compare the efficacy of low dose magnesium sulphate (Dhaka) regim...

The deposition of manganese in a water distribution system with manganese-related "dirty water" problems was studied over a 1-year period. Four monitoring laboratories with Robbins biofilm sampling devices fitted to the water mains were used to correlate the relationship among manganese deposition, the level of manganese in the water, and the chlorination conditions. Manganese deposition occurr...

Manganese is capable of forming complex ions with many substances found naturally in the body (1). It seems reasonable to assume, therefore, that manganese injected as MnSO4 (hereafter referred to as "ionic manganese") will be complexed in the body to a varying extent shortly after administration. If the Mn is strongly chelated before it is injected, a state of competition between ligands is se...

The purpose of this study was to estimate daily intake of manganese in Korean adults. Manganese intake was estimated through the use of the database of manganese content in frequently consumed Korean foods after first conducting anthropometric measurement and a survey on dietary intake with 354 Korean adults. Average age, height, weight and body mass index were 54.6 years, 165.7 cm, 67.2 kg and...

Somers and Shive (37) suggested that the physiological availability of iron in plants is determined by the relative manganese supply and that the optimum growth and yield of plants depend on a certain definite proportion rather than the absolute level of iron and manganese supply. These workers also held that iron deficiency is identical with manganese excess and iron excess with manganese defi...

s-The uronic acid-containing glycosaminoglycans present in the brains of rat, monkey, chicken, sheep and rabbit were isolated into various fractions by combining the cetyl pyridinium procedure and DEAE-Sephadex column Chromatography. The analyses of the fractions show that hyaluronic acid, chondroitin4sulphate, chondroitin-6-sulphate, heparan sulphate and a testicular hyaluronidase-resistant ga...

introduction: controlling parenchymal hemorrhage, especially in liver, is still one of the challenges surgeons face with when they try to save the patients’ lives despite improvements in surgical procedures. there is a research contest between the researchers in this field to introduce more effective methods. this study aimed to compare the hemostatic effect of ferric sulfate and ferric chlorid...

A native microorganism, Penicillium citrinum was isolated from the top soil of a manganese mine. Based on its efficiency for manganese solubilisation, it was utilized for the leaching of a low-grade manganese ore. The effects of various parameters such as pulp density, particle size, sucrose concentration, inoculum size and bioleaching duration on manganese ore were studied. The optimised condi...
