Dendrobium officinale extract shows potent anti-fatigue effects; however, the active substance responsible for these effects remains undetermined. A glucomannan with a huge molecular size of 730 kDa, called DOP, was identified as the unique authentication marker of this expensive herb. DOP exhibited immunomodulating effects on macrophages and lymphocytes in our previous study. Clinical reports ...

The aim of this review article was to summarize accumulated information related to chemical composition, pharmacological activity, traditional and official use of Rhodiola rosea L. in medicine. In total approximately 140 compounds were isolated from roots and rhizome - monoterpene alcohols and their glycosides, cyanogenic glycosides, aryl glycosides, phenylethanoids, phenylpropanoids and their ...

Kocuria rosea belongs to genus Kocuria (Micrococcaceae family, suborder Micrococcineae, order Actinomycetales) that includes about 11 species of bacteria. Usually, Kocuria sp are commensal organisms that colonize oropharynx, skin and mucous membrane; Kocuria sp infections have been described in the last decade commonly affecting immunocompromised patients, using intravenous catheter or peritone...

Catharanthus roseus is a medicinal herb found in many tropical and subtropical regions around the world. This plant produces a diverse array of secondary metabolites that are pharmaceutically important like vinblastine and vincristine used as chemotherapeutic agents in the treatment of several types of cancers. Low yield of these vinca alkaloids from the plant in vivo and the challenges to meet...

AIM OF THE STUDY Rhodiola rosea L. (Crassulaceae) is traditionally used in Eastern Europe and Asia to stimulate the nervous system, enhance physical and mental performance, treat fatigue, psychological stress and depression. In order to investigate the influence of Rhodiola rosea L. roots on mood disorders, three extracts were tested against monoamine oxidases (MAOs A and B) in a microtitre pla...

The clinical and bacteriological features of a case of endocarditis are described in which a Gram-positive coccus, presently designated Micrococcus sedentarius incertae sedis, was repeatedly isolated.

Relatively high transfo mation frequencies were obtained with Micrococcus lysodeikticus cells, previou[ill]sly grown in defined broth, with a tris(hydroxymethyl)-aminomethane-glutamate b uffer containing Mg(++), Ca(++), Ba(++), or Sr(++).

We describe a nephelometric procedure for determination of lysozyme. A quantitative result is obtained in 2 to 3 min with 50 microliter of serum or urine. At a lysozyme concentration of 12.0 mg/liter, between-day precision was 3.4% and the analytical recovery 96.5-105.5%. The values obtained were a linear function of enzyme concentration below 50 mg/liter, and they agreed with those obtained by...
