Estrogenic and anti-amnesic potential of Millettia griffoniana Baill. (Fabaceae) ethanolic extract on scopolamine-induced memory impairment in ovariectomized Wistar rats.

Ethnopharmacological Relevance: Dementias including Alzheimer disease (AD) are three times higher in menopausal women than in men. Phytoestrogens, a group of plant-derived compounds are known to alleviate menopausal complaints including dementia. Millettia griffoniana Baill is a phytoestrogen-rich plant used to treat menopausal complaints and dementia.

HPA-axis activity and the moderating effect of self-esteem in the context of intimate partner violence in Cameroon.

Background: The experience of intimate partner violence (IPV) is stressful. One objective way to monitor it is to assess victims' stress response by measuring the concentration of their salivary cortisol, the major stress hormone released by the hypothalamic-pituitary-adrenal axis.

Objective: We investigated how the IPV experienced by women in Cameroon affects their stress levels and those of their children.

Ameliorative effects of the aqueous extract of Khaya anthotheca (Welw.) C.DC (Meliaceae) in vanadium induced anxiety, memory loss and pathologies in the brain and ovary of mice.

Ethnopharmacological Relevance: Ethnobotanical enquiries have revealed that Khaya anthotheca (Welw.) C.DC (Meliaceae) has anxiolytic properties and is used to alleviate vaginal dryness in postmenopausal women in Cameroon.

From the Mother to the Child: The Intergenerational Transmission of Experiences of Violence in Mother-Child Dyads Exposed to Intimate Partner Violence in Cameroon.

Intimate partner violence (IPV) is a widespread social problem with serious consequences for the health of both women and their children. However, little is known about the combined effect of maternal childhood abuse and current exposure to IPV with respect to the psychopathological symptoms of the mother-child dyad. In a Cameroonian cultural setting, where IPV affects more than half of women, we aimed to better understand how mother's childhood abuse and current IPV co-occur to lead to psychopathological symptoms in the mother-child dyad.

Memory and exploratory behavior impairment in ovariectomized Wistar rats.

Background: Estrogen deficiency is linked to changes in several physiological processes, but the extent to which it associates with cognitive changes in menopause context is controversial.

Rationale: We evaluated the impact of ovariectomy on memory processes and normal exploratory behavior in Wistar rats.

Methods: Young adult rats (4-6 months) were either ovariectomized (OVX group) (N = 10), sham operated (N = 10), or untouched (naïve controls) (N = 8).

Anxiolytic and sedative activities of aqueous leaf extract of Dichrocephala integrifolia (Asteraceae) in mice.

Ethnopharmacological Relevance: Dichrocephala integrifolia (Asteraceae) is commonly used in the folk medicine in Cameroon to treat various ailments including headaches, jaundice, filariasis, neuritis and children's night agitation. It is also known to have anxiolytic properties. Since there were no scientific data supporting the above claims, we therefore aimed to evaluate the anxiolytic and sedative effects of the aqueous leaf extract of D.

Botanicals for mood disorders with a focus on epilepsy.

Mood disorders are among the major health problems that exist worldwide. They are highly prevalent in the general population and cause significant disturbance of life quality and social functioning of the affected persons. The two major classes of mood disorders are bipolar disorders and depression.

Newtonoate as an active principle of Newtonia griffoniana for anxiolytic activity in Swiss mice.

Background: Newtonia griffoniana (Mimosaceae) is a Central African rain forest tree, whose bark extracts are used in Cameroonian folk medicine for the treatment of anxiety and sleep disorders.

Methods: We evaluated the anxiolytic effects of N. griffoniana stem bark methanol extract and its major isolated constituent 2,3,4-trihydroxybutylpentatriacontanoate (newtonoate) on the elevated plus maze.

Phytotherapy and women's reproductive health: the Cameroonian perspective.

Approximately 80 % of the population in Africa use traditional medicinal plants to improve their state of health. The reason of such a wide use of medicinal plants has been mainly attributed to their accessibility and affordability. Expectation of little if any side effects, of a "natural" and therefore safe treatment regimen, as well as traditional beliefs additionally contribute to their popularity.

Modulation of some estrogen-responsive genes in the vena cava of ovariectomised Wistar rats by griffonianone C, an isoflavone derived from Millettia griffoniana Baill. (Fabaceae).

In the present study, we investigated whether griffonianone C (Griff C), extracted from root bark of Millettia griffoniana, changes the expression of several estrogen-responsive genes in the vena cava of ovariectomised rats. For this purpose, we subcutaneously administered Griff C (2, 10, or 20mg/kg/d BW), 17β-estradiol (E2: 10μg/kg/d BW) as positive control, and a vehicle control respectively for three days. Relative expression levels of estrogen receptor α (ERα), progesterone receptor (PR), cyclooxygenase2 (Cox-2), vascular endothelial growth factor (VEGF), VEGF-receptor 2, angiotensin converting enzyme (ACE), endothelial NO synthase (eNOS), proliferating cell nuclear antigen (PCNA) and Ki67 mRNA extracted from the vena cava of these rats were quantified by real-time PCR.
