Resins, pigments and fillers constituents in white latex paint were identified and quantified after previous treatment under both low temperature and low pressure in order to get toilet powder from emulsion samples. TG/DTA allowed, under determined conditions, to distinguish the kind of resins, fillers and pigments in commercial paints. X-ray diffractometry was used to confirm the presence of pigment in the final residue from the thermal decomposition.

Objective: To evaluate the influence of recombinant human erythropoietin (Epho) on carbohydrate metabolism, parathyroid hormone, calcium ionic, zinc, prolactin and blood pressure (BP) in chronic renal failure treated by hemodialysis. Methods: Ten patients in hemodialysis were followed during 24 weeks in two phases: 12 weeks pre-Epho (BP was measured pre and post hemodialysis sessions) and 12 weeks post-Epho (BP was measured as above and also the blood levels of glucose, insulin, parathyroid hormone, calcium ionic, prolactin, and zinc). Results: Patients were 39.8±8.5 y, 50% males. Hematocrit and hemoglobin presented a significant increase four weeks after Epho (22.3±2.3 to 28.1±2.6% and 7.4±0.8 to 9.4±0.9 g/dL, p<0.05). BP (mmHg) and weight pre-Epho: 158±99 and 59±13 (before hemodialysis), 147±96 and 55±13 (after hemo) and post-Epho: 161±100 and 59±13 (before hemo) 155±101 and 56±12 (after hemo) were all not statistically different in any moment. There are also no difference pre and post-Epho in fast glucose (91.8±6.5 and 90.8±6.1 mg/dL, p>0.05), parathyroid hormone (341.4±249.3 and 515.7±310 pg/ mL), calcium ionic (3,66±0.63 and 3.76±0.45 mmol/L), prolactin (males: 327±144.1 and 298.1 ±145.2 μg/mL; females: 666.2±426.6 and 659±395.3 μg/mL) and zinc (median of 0.73 and 0.71 μg\L). Basal insulin was lower after Epho (median of 9.1 to 3.8 μg/mL, p<0.05). Conclusion: These data suggest that recombinant human erythropoietin was effective to improve the anemia and the carbohydrate metabolism in patients with chronic renal failure treated by hemodialysis. © Copyright Moreira Jr. Editors.

The palatoplasty is a correction surgery to restore the isolation between the oral and nasal cavity, avoid breath of food. There are many techniques to repair palatal defects, and the most used is mucoperiosteal flap. Grafts and prothesis, can be used too. Scientific works with Natural Latex Biomembrane with 0,1% Polylisine reveals properties like biocompatibility, improve and accelerate the cicatricial process, the stimulation of new vessels and organized tissue growth in different organs. Seven dogs were arranged in two groups and were submitted to experimental hard palate cleft. Five dogs received palatal repair with the natural latex biomembrane with 0,1% polylisine. Two animals did not receive any repair (control group) and the defect healing by second intention. After surgery, the groups were observed macroscopically and clinically to evaluate the results. The healling of cleft palate of group I was faster than control group, and this fact suggests that the biomembrane is an accelerator factor for cicatricial process.
