Septic encephalopathy (SE) is a common term indicating the development of signs of progressing cerebral dysfunction and is associated with the presence of microorganisms and their toxins in the blood. Aim of this investigation was to analyze the frequency of this complication considering the consciousness disorders in quantitative sense and prognosis of the survival in patients with SE. The investigation comprised patients (n = 54) with positive hemoculture and signs of septic syndrome by the accepted criteria (fever, clinical signs of infection, respiratory frequency, heart rate, plasma lactate, oliguria). Patients with confirmed cerebral injury, hemorrhage or cerebral ischemia were excluded from the study. Lumbar punction and CT-scan of the brain were performed in all patients in order to exclude visible lesions of cerebral parenchyma and eventual presence of cerebral nervous system (CNS) infection as the causes of sepsis. Results of the investigation demonstrated that in 30 (55%) of patients existed mild consciousness disorder at the level of somnolescence, in 18 (33%) consciousness disorder at the level of sopor and in 6 (11%) consciousness disorder at the level of deep coma. Level of consciousness disorder was in positive correlation with the outcome of sepsis syndrome, which was additionally confirmed by the fact that only in the group of patients with deep coma lethal outcome was observed in 3 cases (50% of this subgroup) regardless of intensive antibiotic, metabolically active and symptomatic therapy. It can be concluded that SE syndrome has a favorable prognosis if macroscopic lesion and dissemination of microorganisms in CNS are not present, and simultaneously it represents changes in metabolic-electrolytic state with early presentation of consciousness disorders that represent clinically significant indicator for sepsis syndrome outcome.

Biological and chemical quality control of spermicidal raw material nonoxynol-9 and nonoxynol-9 containing vaginal contraceptive (ABF contraceptive film): determination of spermicidal activity and assay of nonoxynol-9.

The paper presents a routine biological and chemical quality control of nonoxynol-9 raw material and pharmaceutical formulation containing nonoxynol-9 (ABF contraceptive film). The biological control performed based on the determination and comparison of the spermicidal activities different dilutions of the standard raw materials solution and assay raw material or nonoxynol-9 pharmaceutical formulation solution on the human or breeding bull sperm using a modified Sander-Cramer method. The test preparations of the nonoxynol-9 raw materials or pharmaceutical formulation should show equal or higher spermicidal activity than the standard. The spermicidal activity should not be lower than dilution 1:90. The chemical control is performed based on the determination and comparison of nonoxynol-9 content in the standard raw material solution and assay raw material or nonoxynol-9 pharmaceutical formulation solution using UV-spectrophotometric method determining and comparing the absorbances at the maximum absorbance wavelength (275 nm). The content of nonoxynol-9 in the raw material assay solution or pharmaceutical formulation (ABF contraceptive film) should be within 90-110% of the declared value.
