肌松药物巴氯芬类似物的合成及其构效关系的研究

为研究解痉肌松药巴氯芬类似物的构效关系,合成了巴氯芬类似物15个,其中8个化合物是首次报道。采用小白鼠热板法及对抗吗啡竖尾反应实验评价目标化合物的镇痛和肌松作用。筛选结果表明:部分化合物有肌松和镇痛作用,其中Ⅰb,Ⅱb,Ⅲa和Ⅲc的镇痛作用较好,Ⅰd,Ⅱb,Ⅲa和Ⅲb的肌松作用较好,但均未超过巴氯芬。根据本研究及前人的研究结果,提出巴氯芬与GABA_B受体结合取决于巴氯芬分子中氨基、羧基和苯环三种基团。     

Collagenous colitis: an electron microscopic study including comparison with the chronic fibrotic stage of ulcerative colitis

Light and electron microscopic studies of 14 cases of collagenous colitis are reported. Comparative electron microscopic examinations were carried out on 13 cases of ulcerative colitis in the chronic fibrotic stage of the disease. Separation of pericryptal fibroblasts which showed enhanced fibre-forming activity, proliferation of myofibroblasts, accumulation of mast cells and a pericapillary collagen accumulation were noted in both groups. Based on these results, collagenous colitis was considered to result from scar formation secondary to previous superficial inflammation.

Prevalence of Sexually Transmitted Infections Among Men Who Have Sex with Men in Zagreb, Croatia

We used respondent-driven sampling among men who have sex with men (MSM) in Zagreb, Croatia in 2006 to investigate the prevalence of HIV, other sexually transmitted infections and sexual behaviours. We recruited 360 MSM. HIV infection was diagnosed in 4.5%. The seroprevalence of antibodies to viral pathogens was: herpes simplex virus type-2, 9.4%; hepatitis A, 14.2%; hepatitis C, 3.0%. Eighty percent of participants were susceptible to HBV infection (HBs antigen negative, and no antibodies to HBs and HBc antigen). Syphilis seroprevalence was 10.6%. Prevalence of Chlamydia and gonorrhoea was 9.0%, and 13.2%, respectively. Results indicate the need for interventions to diagnose, treat and prevent sexually transmitted infections among this population.     

The emerging and re-emerging human immunodeficiency virus epidemics in Europe

We provide a summary of the current status of the human immunodeficiency virus (HIV) epidemic, including data on the transmission of drug-resistant virus in the European Region of the WHO. The review was conducted by searching the reports of the European Centre for Disease Prevention and Control and the United Nations General Assembly Special Session country reports to identify the number of HIV cases reported in 2002–2011, the number of HIV tests performed, and the results of the most recent HIV surveys in at-risk groups. In the West, a 5-year linear trend analysis suggests an increase in the number of reported HIV cases in Belgium, Greece, and Iceland, and a decline in The Netherlands, Ireland, Portugal, Switzerland, and the UK. In the Centre, the number of reported cases increased in Bulgaria and Turkey, and in the East, the number of reported cases increased in Armenia, Georgia, and Ukraine. Estonia and Latvia reported a significant downward trend. HIV transmission in men who have sex with men (MSM) and heterosexual transmission accounted for, respectively, 40% and 38% of newly reported HIV cases in the West in 2011, whereas the epidemic in the Centre is predominantly concentrated in MSM. Although injection drug use remains the key driving force of the epidemic in the East, there is increasing evidence of sexual transmission from the core groups of injection drug users, and increasing spread within MSM. The pattern of transmitted drug resistance (TDR) is heterogeneous accross Europe; a significant number of clusters of TDR have been recently observed in several European countries.     

THE METABOLIC CONSEQUENCES OF HUMAN MILK AND FORMULA FEEDING IN PREMATURE INFANTS

Abstract. Schultz, K., Soltész, G. and Mestyán, J. (Department of Paediatrics, University Medical School, Pécs, Hungary). The metabolic consequences of human milk and formula feeding in premature infants. Acta Paediatr Scand, 69: 647, 1980.—Twenty premature low-birthweight infants were divided into two groups and assigned randomly to either a pooled human milk or to a cow's milk based infant formula feeding regimen. The protein intake was 2.0 g/kg/day in the human milk fed group and 4.4 g/kg/day in the formula fed group of infants. The concentrations of different metabolites were estimated at weekly intervals, and plasma amino acid analysis was performed biweekly on blood samples in the two groups of infants during the four-week study period. Formula milk fed infants had significantly lower fasting blood glucose levels and developed azotaemia, hyperaminoacidemia and metabolic acidosis in the early weeks of postnatal life. Blood lactate and plasma free fatty acid concentrations did not change significantly in the two groups during the study. No significant differences were found in the rate of weight gain between the two groups of infants, although formula fed infants regained their birthweight more slowly than human milk fed infants. High protein formula feeding causes potentially unfavorable metabolic and amino acid imbalances in preterm infants in the early postnatal life.
