Intraperitoneal administration of sodium oestrone [(35)S]sulphate to male and female free-ranging guinea pigs is followed by excretion of most of the radioactivity mainly as inorganic [(35)S]sulphate in the urine within 72h. The remainder of the radioactivity in the urine was found in oestrone [(35)S]sulphate, two unidentified metabolites (A and B) and traces of oestradiol-17beta 3-[(35)S]sulph...

BACKGROUND Magnesium sulphate has been used in some settings as a tocolytic agent to inhibit uterine activity in women in preterm labour with the aim of preventing preterm birth. OBJECTIVES To assess the effects of magnesium sulphate therapy given to women in threatened preterm labour with the aim of preventing preterm birth and its sequelae. SEARCH METHODS We searched the Cochrane Pregnanc...

To assess the antirheumatic activity of zinc sulphate, 27 patients with active rheumatoid arthritis took part in a 6-month, randomised, double-blind, between-group trial of oral zinc sulphate versus placebo. Twelve patients on zinc and 9 on placebo completed the trial, but no significant antirheumatic activity of zinc sulphate was demonstrated.

Eclampsia, the occurrence of a seizure in association with pre-eclampsia, remains an important cause of maternal mortality. Although it is standard practice to use an anticonvulsant for management of eclampsia, the choice of agent is controversial and there has been little properly controlled evidence to support any of the options. 1687 women with eclampsia were recruited into an international ...

A mouse monoclonal antibody (AN9P1) to keratan sulphate is described. In a competitive-inhibition solution-phase radioimmunoassay employing l25l-labelled intact proteoglycan, it reacts preferentially with keratan sulphate bound to the core protein of adult human articular-cartilage proteoglycan and to a much lesser degree with keratan sulphate purified from this proteoglycan. Proteolytic cleava...

Glycosaminoglycan heparan sulphate interacts with a variety of proteins, such as growth factors, cytokines, enzymes and inhibitors and, thus, influences cellular functions, including adhesion, motility, differentiation and morphogenesis. The interactions generally involve saccharide domains in heparan sulphate chains, with precisely located O-sulphate groups. The 6-O-sulphate groups on glucosam...

A novel glycosulphatase has been purified from a mucus glycopeptide-degrading Prevotella from the colon. The purified enzyme removed inorganic [35S]sulphate from 35S-labelled native rat gastric mucus glycoprotein. Desulphation of mucus glycoprotein was initially rapid (19% complete after 10 min) but then plateaued, reaching only 33% after 3 h. Crude periplasmic extracts could remove 79% of the ...

Sulphated N-acetylhexosamines have been isolated from human urine and tentatively identified as N-acetylglucosamine 6-sulphate (GlcNAc6S), N-acetylgalactosamine 6-sulphate (GalNAc6S), N-acetylgalactosamine 4-sulphate (GalNAc4S) and N-acetylgalactosamine 4,6-disulphate (GalNAc4,6diS). Urine from mucopolysaccharidosis-Type-IIID, -IVA and -VI patients compared with that from normal individuals con...

Sulphate, the fourth most abundant anion in human several considerations raise the possibility that certain plasma, is known to play an essential role in a variety of the skeletal abnormalities seen in vitamin D of biochemical processes [1]. The importance of deficiency could result from abnormal sulphate metasulphate has been demonstrated recently by the identibolism. First, a number of the pa...
