Tele-methylhistamine distribution in rat brain.
EVIDENCE accumulated from a variety of biochemical and physiological observations makes it likely that histamine serves as a transmitter in mammalian brain (GREEN el af., 1977; SCHWARTZ, 1977). The metabolic fate of brain histamine is methylation, yielding tele-methylhistamine [1-methyl-4-(~-aminoethyl)-imidazole, t-MHJ. For the structure or a nomenclatural discussion see BLACK & GANELLIN (1974...
متن کاملGas chromatography--mass spectrometric characteristics and assay of tele-methylhistamine.
To date, te/e-methylhistamine, the product of enzymatic histamine methylation, has not been measured by a suitable method. Tefeandpros-methylhistamine both react quantitatively with trifluoroacetic and heptafluorobutyric anhydrides at room temperature under anhydrous conditions to yield either monoor bis-derivatives in the absence or presence of pyridine, respectively. The extraction of tissue ...
متن کاملA STUDY COMPARING CEREBROSPINAL FLUID LACTATE LEVELS IN CHILDHOOD CULTURE POSITIVE AND CULTURE NEGATIVE MENINGITIS
Despite recent innovations in the laboratory diagnosis of bacterial from nonbacterial meningitis, solid data-necessary for early determination of bacterial meningitis (BM) before organism growth in the culture medium-are missing. Therefore cerebrospinal fluid (CSF) lactate levels were evaluated as a possible means of differentiating the two clinical entities. This was a retrospective study....
متن کاملEnterobius vermicularis in Cerebrospinal Fluid
Enterobius vermicularis is a nematod of large intestine in man. Extra intestinal localization of this parasite is rare. A 60 year old man was admitted to the hospital with the clinical manifestation of meningitis. In laboratory examination of cerebrospinal fluid (C.S.F), the appearance was red, Albu-min level was high and the glucose showed normal value. Haematoxylin and Eosin stained slides pr...
متن کاملCerebrospinal Fluid Apolipoprotein E Levels in Delirium
BACKGROUND/AIMS Delirium and the apolipoprotein E ε4 allele are risk factors for late-onset Alzheimer disease (LOAD), but the connection is unclear. We looked for an association. METHODS Inpatients with delirium (n = 18) were compared with LOAD outpatients (n = 19), assaying blood and cerebrospinal fluid (CSF) using multiplex ELISA. RESULTS The patients with delirium had a higher Confusion ...
