Effect of DHEA therapy on sexual behavior in female rats.

Delta-5 androgen therapies seem to enhance the sexual response in experimental animal models and in clinical trial. This study analyzed the influence of dehydroepiandrosterone (DHEA) administration on receptive and proceptive components of female rat sexual behavior. Ovariectomized (OVX) adult rats were divided in six groups submitted to the following treatments for 4 weeks: DHEA 0.

Structural and histomorphometric evaluations of ferutinin effects on the uterus of ovariectomized rats during osteoporosis treatment.

Aims: The effects of chronic administration of Ferutinin (phytoestrogen found in the plants of genus Ferula), compared with those elicited by estradiol benzoate, were evaluated, following ovariectomy, on the uterus of ovariectomized rats as regard weight, size, structure and histomorphometry.

Main Methods: The experimental study included 40 female Sprague-Dawley rats, assigned to two different protocols, i.e.

Influence of Griffonia simplicifolia on male sexual behavior in rats: behavioral and neurochemical study.

The seeds of Griffonia simplicifolia Baill. are rich in 5-HTP (5-hydroxytryptophan), a direct precursor of the neurotransmitter serotonin. In the present study we investigated the influence of the plant extract on male sexual behavior.

Anxiolytic-like effect of Griffonia simplicifolia Baill. seed extract in rats.

The seeds of Griffonia simplicifolia Baill., a tropical shrub native to West Africa, are rich in 5-hydroxy-l-tryptophan (5-HTP), a direct precursor in the synthesis of serotonin (5-HT). In spite of the modern therapeutic application of Griffonia simplicifolia seed extract in mood disorders, no scientific evidence has been provided till now.

Increased sexual motivation in female rats treated with Humulus lupulus L. extract.

Aim Of The Study: To evaluate the influence of Humulus lupulus extract on sexual behavior in female rats.

Materials And Methods: Ovariectomized rats hormonally primed with estradiol benzoate (1.5 μg/rat) and progesterone (500 μg/rat) were acutely treated by oral gavage with Humulus lupulus extract dosed at 5, 10 and 25mg/kg and then tested for partner preference and sexual receptivity.

Quantitative analysis of acetylcholine in rat brain microdialysates by liquid chromatography coupled with electrospray ionization tandem mass spectrometry.

A liquid chromatography tandem mass spectrometry (LC/MS/MS) method has been developed for the quantitative analysis of acetylcholine in rat brain dialysates. The separation of acetylcholine (ACh), choline (Ch), acetyl-β-methylcholine (IS) from endogenous compounds and Ringer's salts was achieved with cation exchange chromatography. Optimization of chromatographic and mass spectrometry parameters were perfomed in order to improve sensitivity of the method.

Griffonia simplicifolia negatively affects sexual behavior in female rats.

At present Griffonia simplicifolia is used in food supplement aimed to treat mood disorders as well as to reduce food intake and body weight. The plant has gained increasing interest for its high content in 5-hydroxy-L-tryptophan (5-HTP) particularly in the seed. The present study was designed to evaluate the influence of a seed extract of the plant, dosed at 25, 50 and 100 mg/kg, on the sexual behavior of ovariectomized hormone-primed rats after acute and subchronic treatment.
