OBJECTIVE To assess the effect of the lipidosterolic extract of Serenoa repens (LSESr) on in vitro cell proliferation in biopsies of human prostate MATERIAL AND METHODS Cell proliferation was assessed by incorporation of [3H]thymidine followed by historadiography. RESULTS Basic fibroblast growth factor (b-FGF) induced a considerable increase in human(More)
BACKGROUND The growth of the prostate gland is mainly dependent on androgens. Other hormones, like prolactin (PRL), also influence prostate development. Our purpose was to analyze and compare the effects of two drugs (5alpha-reductase inhibitor) used in the therapy of benign prostatic hyperplasia: lipidosterolic extract of Serenoa repens (LSESR), and(More)
BACKGROUND Chondroitin sulfates (CS) are involved in articular metabolism and could be used as therapeutic agents in degenerative articular diseases. OBJECTIVES To review the published reports describing both the metabolism of glycosaminoglycans (GAG) and their involvement in osteoarticular pathophysiology. METHODS MEDLINE search for relevant articles(More)
In different cell systems, the lipido-sterolic extract of Serenoa repens (LSESr, Permixon inhibits both type 1 and type 2 5alpha-reductase activity (5alphaR1 and 5alphaR2). LSESr is mainly constituted of fatty acids (90+/-5%) essentially as free fatty acids (80%). Among these free fatty acids, the main components are oleic and lauric acids which represent(More)
A series of 1-aryl-2-(aminomethyl)cyclopropanecarboxylic acid derivatives were synthesized and evaluated as potential antidepressants. Compounds with the Z configuration were synthesized from 1-aryl-2-oxo-3-oxabicyclo[3.1.0]hexane and those with the E configuration from (E)-1-phenyl-2-(hydroxymethyl)cyclopropanecarboxylic acid. The compounds were evaluated(More)
Although the lipidic extract of Serenoa repens (LESSr, Permixon, Sereprostat) is widely used in patients suffering from benign prostatic hypertrophy (BPH), its mechanism of action is not fully elucidated. It has been demonstrated that infiltration of the prostate by inflammatory cells is one of the aetiologic factors involved in the development of BPH.(More)
The study carried out on rats given orally the n-hexane lipido/sterolic extract of Serenoa repens (LSESR), supplemented with [14C]-labelled oleic or lauric acids or beta-sitosterol, demonstrated that radioactivity uptake in prostatic tissues shows the highest level in the case of administration of LSESR supplemented with [14C]-labelled oleic acid. This was(More)
The study carried out on rats given orally then-hexane lipido/sterolic extract ofSerenoa repens (LSESR), supplemented with [14C]-labelled oleic or lauric acids or β-sitosterol, demonstrated that radioactivity uptake in prostatic tissues shows the highest level in th case of administration of LSESR supplemented with [14C]-labelled oleic acid. This was(More)
Acetyl-DL-leucine [2-14C]: Tanganil® a antivertigal drug has been injected intravenously in two macaca monkeys which have been sacrificed 2 and 5 minutes later. Radioactivity distribution has been studied by autoradiography in the brain. An important uptake of radioactivity is localized in the cortical structures and in several tisses such as nuclei of the(More)
