Analysis of nursing dissertations and theses on mental health, Brazil, 1979-2007.

This bibliographic study analyzes scientific texts published in the CEPEn database in the mental health field (1979-2007). A total of 280 abstracts were investigated, of which 208 were Master's theses. The individuals investigated in these studies were professionals (57), patients (50), and professors and/or students (18). Among the themes addressed between 2000 and 2007 were the following: Nursing Care in Mental Health (40), Perception in Mental Health (37); and Transversality in Mental Health Care (27). This study provided an overview of the scientific research produced in the mental health field in Brazilian nursing graduate programs. We expect this study to elicit reflections concerning mental health care practice and enable new approaches for nursing promoting health and the prevention of diseases in order to enable patients to recover their citizenship, autonomy and quality of life.

Subjectivity and sexuality production in women living with HIV/aids: a sociopoetic production.

The study aims to apprehend the subjectivity production possibilities concerning sexuality in a group of women living with HIV/aids, based on the sociopoetic method. The subjects were nine women with HIV/aids attended at the public referral hospital for infectious diseases in Fortaleza-CE. The results appoint that sexuality appears in several dimensions: in the sexual act, in knowing their own body, in professional accomplishment, in feelings of desire and love, besides the feeling of freedom. We concluded that sexuality is present in the individual's totality; it is not limited to the sexual act, but goes much further and is characterized as a dynamic reality.

Antispasmodic effect of Mentha piperita essential oil on tracheal smooth muscle of rats.

AIM OF THE STUDY: Mentha piperita is a plant popularly known in Brazil as "hortelã-pimenta" whose essential oil is used in folk medicine for its anti-inflammatory, antispasmodic, expectorant actions and anti-congestive. Here, it was investigated the effect of Mentha piperita essential oil (peppermint oil) in rat tracheal rings along with its mechanism of action. MATERIALS AND METHODS: Tracheal tissue from male Wistar rats (250-300 g) were used. Peppermint oil was added in cumulative concentrations [1-300 microg/ml] to the tissue basal tonus or pre-contracted by carbachol [10 microM] at 10 min intervals, incubated or not with indomethacin [10 microM], L-N-metyl-nitro-arginine [100 microM], hexamethonium [500 microM], or tetraethylammonium [5 mM]. RESULTS: Peppermint oil [100 and 300 microg/ml] inhibited the contractions induced by carbachol, which was reversed by indomethacin, L-N-metyl-nitro-arginine and hexamethonium, but not by tetraethylammonium. These data suggest the participation of prostaglandin E(2), nitric oxide and autonomic ganglions in the peppermint oil relaxant effect and may be correlated with its popular use in respiratory diseases. CONCLUSIONS: Peppermint oil exhibited antispasmodic activity on rat trachea involving prostaglandins and nitric oxide synthase.
