In the present study we describe the cell types containing immunoreactive vasoactive intestinal peptide (IR-VIP) in rat thymus, spleen, and lymph nodes. Indirect immunofluorescence staining and flow cytometry indicated that all lymphoid organs studied contained VIP-positive cells, with the spleen and lymph nodes having a higher proportion than the thymus.(More)
OBJECTIVE To describe the reasons for eventual dissatisfaction among the families of patients who died in the intensive care unit (ICU), regarding both the assistance offered during the patient's stay in the hospital and the information received from the medical staff. DESIGN Cross-sectional descriptive study, which was conducted after a survey using a(More)
All of the essential technological means of treating grapes, must and wine were examined systematically. The main reasons for the differences in the arsenic (As) content of rosé and red wines are explained. In this study a relationship has been found between the As level and the wine-making technique. Rosé wines contain more As than red wines because they(More)
In the present paper, we have studied the impact of lactation upon fertility in the capuchin monkey, Cebus apella, under laboratory conditions. Nursing females (ten females, 12 postpartum periods) presented lactational amenorrhea (first menses at 159.2 +/- 9.0 vs 42.6 +/- 5.8 days postpartum in five non-nursing females, seven postpartum periods). Plasma(More)
The main purpose of this research was to study the effects of water movement on arsenic absorption. In order to appreciate and measure the interaction between these two variables we investigated the perfusion of isotonic and hypotonic buffers (containing 3.2 microgram/ml As2 O5 into rat small intestines. The As (V) depended on osmolarity sensitive. This(More)
Death from traumatic shock has been associated with loss of blood externally or internally. However, many patients die after trauma, even though blood volume restoration is adequate. Death is often due to pulmonary failure (adult respiratory distress syndrome [ARDS]). Death and ARDS have been associated with disseminated intravascular coagulation (DIC) and(More)
One hundred children, ranging in ages from a month to a year, with acute diarrhea who were treated at home following the basic standard recommendations, were studied. In order to prevent dehydration, half of the children were given oral solution (OS) containing the concentrated official formula in packets (group A), and the remaining half was given a(More)
Hearing loss (HL) was prospectively studied in 236 children with meningitis using brainstem auditory evoked responses. Hearing loss was detected in 38 (16.1%) in the acute phase of the disease and in 10 (5.2%) of 193 patients who were tested 6 months later. Hearing loss was more frequent and more severe in patients with bacterial meningitis (25.4% in the(More)
Sero-epidemiological data from endemic amoebiasis areas are difficult to evaluate because the serology of individuals affected by an active process of Entamoeba histolytica tissue invasion is, at present, almost impossible to distinguish from that of individuals who have had an invasive event in the past. The present study compares serum antigenic(More)
