The major surface glycoprotein (MSG) of Pneumocystis carinii f. sp. carinii consists of a heterogeneous family of proteins that are encoded by approximately 100 unique genes. A genomic expression library was screened with a panel of MSG-specific monoclonal antibodies (MAbs) to identify conserved and rare epitopes. All of the antibodies reacted with epitopes that are encoded within the 5' end of...

conclusions in the literature, it was observed that short-term msg exposure does not cause significant histological changes in the kidneys, liver, or brain cortex. these findings should be re-evaluated in additional long-term studies. background monosodium glutamate (msg) is a widely-used flavor enhancer and stabilizer in ready-made or packaged foods. the excessive use of msg has been shown to ...

In order to prove sodium toxicity of MSG, baby chicks known to be the most susceptible one to sodium chloride were chosen as the experimental animal. Almost isotonic solution of MSG, NaCI or monopotassium glutamate was given ad libitum as the sole source of drinking water. Two-day old chickens given MSG died of gout within a few days and showed higher mortality and lesions severer than those gi...

Serum levels of luteinizing hormone (LH), follicle stimulating hormone (FSH), prolactin, estradiol-17 beta and testosterone were determined in adult rats that were treated in the neonatal period with monosodium L-glutamate (MSG) which has previously been shown to reliably produce destruction of arcuate nucleus perikarya. MSG-treated males had significantly smaller accessory sexual organs (semin...

Analysis of the Pneumocystis murina MSG gene family and expression-site locus showed that, as in Pneumocystis carinii, P. murina MSG genes are arranged in head-to-tail tandem arrays located on multiple chromosomes, and that a variety of MSG genes can reside at the unique P. murina expression site. Located between the P. murina expression site and attached MSG gene is a block of 132 basepairs th...

BACKGROUND The human diet has altered markedly during the past four decades, with the introduction of Trans hydrogenated fat, which extended the shelf-life of dietary oils and promoted a dramatic increase in elaidic acid (Trans-18.1) consumption. Food additives such as monosodium glutamate (MSG) and aspartame (ASP) were introduced to increase food palatability and reduce caloric intake. Nutrige...

AIMS The aim of the present study was to evaluate the effects of acute and chronic exposure to alcohol on taste responses to a prototypic umami substance, monosodium glutamate (MSG). METHODS The rated intensity and pleasantness of MSG taste (0.03-10.0%) was compared in chronic male alcoholics (n = 35) and control subjects (n = 25). In a separate experiment, the effects of acute exposure of th...

Neonatal administration of MSG leads to a syndrome of endocrine dysfunction characterised by reduced growth, obesity and hypogonadism. The aim of the present investigation was to gain information on the structure and function of the pituitary-thyroid axis in MSG-treated rats. Neonatal Wistar rats received an s.c. MSG (4 mg/g body weight) or hyperosmotic saline (controls) on days 2, 4, 6, 8 and ...

Monosodium glutamate (MSG) was given to neonatal male rats to determine its effects on neurons containing beta-endorphin (beta-END) and alpha-melanocyte stimulating hormone (alpha-MSH) within the basal hypothalamus (arcuate nucleus) and caudal medulla [nucleus tractus solitarius (NTS)] and on the levels of beta-END and alpha-MSH within these areas. Immunocytochemical studies demonstrated a redu...
