Comparative Study
Intra-dorsal hippocampal microinjections of lithium and scopolamine induce a cross state-dependent learning in mice.
Lithium, a mood stabilizer, may exert adverse effects on memory. We have previously shown that lithium induces state-dependent learning. Cholinergic systems of the brain may play an important role in memory function and mood regulation. In the present study, the effects of intra-dorsal hippocampal (intra-CA1) injections of lithium and scopolamine on memory and cross state-dependent learning between the two drugs were investigated. ⋯ The results suggest that microinjections of both lithium and scopolamine induce state-dependent memory and there may be a cross state-dependency between the two drugs.

Assessment of nasal airway is helpful in understanding nasal breathing function. Acoustic rhinometry is one of the most commonly-used objective measurements of nasal airway. This test has the ability to measure the volume and the cross-sectional area of the nose in different distances. ⋯ There was a significant increase in volume and cross-sectional area after decongestion. Because of the differences in volume and minimal cross-sectional area in various races, measurement of these values in Iranian population is a proper way for diagnosis of rhinologic diseases and planning the appropriate treatment (medical or surgical). It is also helpful for comparison of preoperative and postoperative results after nasal surgeries.

Violence against women and threat of violence are some of the main barriers to women's empowerment and equal participation in the society. However, they often go unnoticed and undocumented and therefore unresolved. For women, one of every five years of healthy life lost because of injury, disease, or premature death is attributable to violence. The aim of this study was to identify the prevalence of domestic violence in women attending three obstetric and gynecologic clinics in Tehran, and to determine the association between domestic violence and demographic factors. ⋯ With the high prevalence of domestic violence, health workers should not ignore the seriousness of domestic violence. Health and social personnel should be appropriately trained before "asking all cases" becomes a policy within health and social services.

To evaluate the processes of care and outcomes of injured patients, many different models have been devised and "Trauma and Injury Severity Score" and "A Severity Characterization of Trauma" score have been among the most widely used models. We conducted this study to determine the effectiveness of these systems of evaluation to our setting in Iran, which is substantially different from the North American trauma centers, where these models were developed. Using our data registry on trauma patients, we derived new coefficients for Trauma and Injury Severity Score and A Severity Characterization of Trauma scoring systems to calculate the probability of survival of patients. ⋯ Discrimination in blunt injuries was a little lower, yet satisfactory. In pediatric patients the discrimination was also good and A Severity Characterization of Trauma had a better performance. Both models can be used reliably to predict outcome of trauma patients in our setting.
