ABSTRACT
Objective To explore the bacterial spectrum and drug resistance that separated from respiratory tract of schizophrene.Methods 311 samples taken from the respiratory tract of schizophrenes were investigated and analyzed.Results From 311 samples 58 pathogenic bacteria were separated,the gram negative was 55.93% and the gram positives was 44.07%;5 most pathogenic commoly bacteria were klesbsiella pneumoniae and S.aureus and escherichia coli and streptococcus and enterococcus;Except that all the staphylococcus were sensitive to vancomycin,enterobacteriaceae were sensitive to imipenem,all the other separated strains showed total resistance to the agents tested in different levels,also the multidrug resistance emerged in lower respiratory tract infections with mulitidrug resistance in high levels.Conclusion The most common pathogenic bacteria separated from these schizophrene are klesbaiella pneumoniae and S.aureus.In clinical therapy,sensitive antibiotics should be selected according to the drug sensitive tests,combine with other agents when necessary to accelerate the clearance of bacteria from infectious respiratory tract in schizophrene.
ABSTRACT
Objective To analyse the relationship between catechol-O-methyltransferase (COMT) activity and affective disorders, and explore the biological mechanism of the etiology of affective disorders.Methods The activities of erythrocytes COMT from 112 affective disorders and 120 normal control were measured with high performance liquid chromatography, all examined data were tested by SPSS 11.0v.Results COMT activity frequency distribution of patients group and control group are at the range of 2～23nmol/ml RBC/hr and 7～28nmol/ml RBC/hr respectively. The average activity of COMT in patients group and control group were (11.0±3.8) nmol/ml RBC/hr and (16.1±4.3) nmol/ml RBC/hr representatively. COMT activity in male and female patient were (11.2±3.7) nmol/ml RBC/hr and (10.6± 4.0) nmol/ml RBC/hr., male and female in control group were (16.5 ±4.6) nmol/ml RBC/hr and (15.4±3.9) nmol/ml RBC/hr, there were significant difference between patients group and control group and also between male and female (P <0.001).conclusion The activity of erythrocytes COMT in affective disorders is lower than normal population and suggested that the lower COMT activity of erythrocytes is associated with affective disorders.
ABSTRACT
Objective:To explore the plasma catecholamines (CAs) concentration of postnatal depression and to analyze the relationships between postnatal depression and CAs level. Methods:Using high performance liquid chromatography (HPLC) to measure the subjects' plasma noradrenaline (NE)?adrenaline (E) and dopamine (DA) concentration. The postnatal depression group was compared with depression, ante partum and normal group.Results: NE level of plasma in the depression group and the postnatal depression group were all higher than those of normal group P 0.05) .Conclusion:the plasma NE increase is relative to postnatal depression episode,the plasma DA may be relative to postnatal depression episode. The relationship between plasma and postnatal depression remains unclear.
