Intense immunoreactivity for Mn-superoxide dismutase (Mn-SOD) in cholinergic and non-cholinergic neurons in the rat basal forebrain

The immunohistochemical localization of manganese (Mn)-superoxide dismutase (Mn-SOD) was studied in the rat basal forebrain using polyclonal antibodies to Mn-SOD. Neurons of the basal forebrain exhibit a high density of Mn-SOD immunoreactivity. Double immunostaining with a monoclonal antibody to choline acetyltransferase demonstrated that both cholinergic and non-cholinergic neurons in the basal forebrain are intensely immunoreactive for Mn-SOD.     

Significance of the studies of urinary syndrome in clinical practice]

The study of urinary sediment is essential in laboratory diagnosis. Conventional clinical methods are now used in line with computer-aided techniques and additional microscopy of the sediment elements. The paper provides a brief analysis of clinical situations characterized by appearance in the urine of abnormal numbers of leukocytes, erythrocytes, casts; provides clinical assessment of additional microscopic methods able to accentuate qualitative characteristics of the urinary syndrome; considers possibilities of application of the urinary sediment data in follow-up to improve diagnosis and control on-going treatment.     

A nursing approach to the management of type IIA hyperlipidemia: case study of a young adult

This case study illustrates the chronic nature of hyperlipidemia type IIa and the important contribution of the nurse in helping the client adjust life style, manage complex health regimes, and cope with the uncertainty of disease progression and its associated risks.     

Human alpha-fetoprotein and its purification by chromatography on immobilized estrogens.

Human alpha-fetoprotein (AFP) was isolated from human abortive tissue by biospecific chromatography on immobilized estrogens. The most effective sorbents were: estrone-0-3-hemisuccinyl-hexamethylenediamine-Sepharose CL 4B and diethylstilbestrol-diasoanisole-sulfonyl-oxyethyl-Sepharose CL 4B. As elution solution the most optimum was 10% buffered aqueous butanol. Taking into consideration the data obtained, one can conclude that AFP in human biological fluids is bound to immobilized estrogens. Butanol extraction deestrogenizes AFP, and as a result human AFP acquires affinity to immobilized estrogens. During rechromatography on immobilized diethylstilbestrol, it was possible to obtain AFP preparations of about 95% purity. The present results provide the opportunity to work out new methodological approaches to human AFP isolation using biospecific chromatography on immobilized estrogens.     

New indole alkaloid glycosides from Nauclea orientalis

Two new indole alkaloid glycosides, 10-hydroxystrictosamide and 6'-O-acetylstrictosamide, as well as the known alkaloids strictosamide and vincosamide were isolated from the leaves of Nauclea orientalis L. The structures of the isolated compounds were determined using spectroscopic methods, mainly 1D- and 2D-NMR spectroscopy.
