Influence of lycopene and astaxanthin in feed on metabolic parameters of laying hens, yolk color of eggs and their content of carotenoids and vitamin A when stored under refrigerated conditions.

Orientating investigations were carried out in order to test the influence of oil extracts of lycopene (20, 40 and 60 mg/kg feed) and astaxanthin (10, 20 and 30 mg/kg feed) as feed additives on the metabolic parameters (glucose, creatinine, cholesterol) and enzyme activities (alanine aminotransferase, ALT; aspartate transaminase, AST) of laying hens. Eggs from these hens were stored at refrigerator temperatures of 4°C and 12°C for up to 30 days and analyzed for vitamin A, carotenoid and yolk color. 45 laying hens (Hy-Line W36 cross, 23 weeks of age) were divided in three groups of 15 birds each (control, lycopene fed group, astaxanthin fed group).

Pneumocephalus associated with epidural and spinal anesthesia for labor.

Headache resulting from dural puncture in epidural and spinal anesthesia is usually secondary to a CSF leak. Pneumocephalus may also occur in this setting but has not been well-characterized. Although the risk factors for a CSF leak and pneumocephalus may overlap, their rates, clinical features, and treatments may be different.

[Antibiotic prophylaxis in the abdominal surgery in children at an early age].

Conduction of antibioticoprophylaxis (ABP) promotes the lowering of frequency of purulent-septic complications occurrence after performance of urgent intervention on organs of abdominal cavity in children aged up to 3 years, prevention of nosocomial infection occurrence, ABP is necessary to conduct, taking into account the microbes strain resistance to antibacterial preparations, defining possible "microbe--leader". During performance of conditionally clean operation ABP is conducted using intravenous injection of the antibiotic daily dose while doing premedication. For this the cephalosporines of II generation, aminoglycosides, metronidazole, are applied.
