and the total hepatic DNA were determined. In Experiment 3, the incidence of hepatic carcinoma was determined for various exposure durations to 0.03, 0.01, 0.003, and 0.001% 2-FAA. At 42 days after the start of administration of 0.03% 2-FAA, the uptake of TdR-3H in the hepatic DNA increased markedly. With 0.03% 2-FAA, the pulse labeling index increased progressively between 42 and 120 days, whi...

Fluoride release into deionized water from two glass-ionomer cements (Aqua Ionofil and Ceramfil β) and two polyacid-modified composite resins or compomers (Hytac and Dyract AP) was examined over different time periods. Nine cylindrical specimens (2.5 x 8.5 mm) of each material were prepared and allowed to stand in deionized water. The resulting solutions were analyzed for fluoride by the Alizar...

Using an autoradiographic technique, the localization and concentration of progestin (P) in cell constituents of testes from the immature 25-to-70-day-old and mature 120-day-old chickens were investigated. After incubation of the frozen tissue sections with 3H-Promegestone (R5020), a synthetic P, specific radioactivity, was found in the seminiferous epithelium and interstitium in all the animal...

AIM The objective of this study was to estimate the effect of orlistat alone and in combination with Garcinia cambogia on visceral adiposity index (VAI) in obese patients. PATIENTS AND METHODS A total of 99 obese male patients were recruited with aged range between 37 and 46 years. They were randomized into three equal groups, first group treated with orlistat 120 mg/day, second group treated...

In order to evaluate Callithrix jacchus as an animal model for mansoni schistosomiasis, a group of 10 male animals were once percutaneously exposed to 250 cercariae of the Schistosoma mansoni SLM (São Lourenço da Mata) strain. Animals were periodically bled for measuring serum level of enzymes and proteins and for blood cell counting. When comparing pre-infection to post-infection values, a sig...

The present study was aimed to investigate the effect of environmentally relevant levels of lead exposure during gestational and early postnatal period on hippocampal dependent spatial memory in rats during adulthood. The pregnant rats were allowed to drink either normal water (control group) or 0.2% lead acetate solution (Lead treated group) during pregnancy and lactation. Thus rats pups of le...
