Hepatic alterations in the fish Rhamdia quelen contaminated with Folidol 600®.

This study has the aim of verifying the morphologic alterations in the hepatic tissue of Rhamdia quelen juveniles when exposed to 0.01 mL/L of Folidol 600. Techniques of light microscopy and transmission electronic microscopy were used.

Talc inhalation is a life-threatening condition.

A case of rapidly progressive disease and pulmonary hypertension due to chronic cosmetic talc inhalation is presented. Although an uncommon cause of pulmonary hypertension, talc, especially through intravenous administration, should be included in the etiology of parenchymal pulmonary hypertension. In our case talc inhalation was inadvertent, causing fulminant disease leading to the patient's death.

Do drug costs affect physicians' prescription decisions?

Objective: To study the impact of the cost of pharmaceuticals on physicians' decisions about drug prescription.

Design: A simulation protocol for the treatment of two patients, one with mild and the other with a severe form of urinary tract infection (UTI), was designed. Thirty family physicians in outpatient clinics and 30 physicians in the internal medicine wards of a Community Hospital participated in the project.

Aspirin modulates interleukin-3 production: additional explanation for the preventive effects of aspirin in antiphospholipid antibody syndrome.

Objective: The granulocyte macrophage colony stimulating factors (GMCSF) and interleukin-3 (IL-3) are defined as positive signals for pregnancy, since they support the process of trophoblast invasion and expansion and induce placental growth and development. Aspirin and IL-3 were shown to be effective in preventing the manifestations of experimental antiphospholipid antibody syndrome (APS). Aspirin inhibits the activity of the enzyme cyclooxygenase in macrophages, which leads to a shift in the arachidonic acid metabolism toward the lipoxygenase pathway, and results in overproduction of leukotrienes.

Divergent age-associated patterns of high density lipoprotein cholesterol and its percentage in Jewish and Moslem Arab Israeli children and adolescents: the Petach Tikva Project.

We studied three groups of Israeli Jewish schoolchildren in and surrounding Petach Tikva, Israel, cross-sectionally, at ages 9-10, 13-14, and 16-18 years, and compared lipid and lipoprotein levels and age-associated lipoprotein patterns in the same age groups of boys and girls in neighboring Israeli Moslem Arab schools during 1986-1987. Moslem children displayed striking differences in the levels of lipids and age-associated patterns of lipoproteins compared with Jewish schoolchildren. The mean total cholesterol levels were lower in the Moslem children, in both sexes, in every age grouping.
