37. Estudo clínico randomizado para profilaxia das complicações tromboembólicas pós-implante transvenoso de dispositivos cardíacos eletrônicos em pacientes de alto risco / Randomized controlled clinical trial for the prevention of thromboembolic complications after transvenous cardiac devices implantation in high risk patients
I ntrodução: A incidência de lesões venosas pós-implante transvenoso de dispositivos cardíacos eletrônicos implantáveis (DCEI) é elevada, sendo a disfunção ventricular e o uso prévio de marcapasso temporário (MPT) ipsilateral ao implante definitivo fatores de risco independentes para sua ocorrência. A utilidade de estratégias terapêuticas pro

38. AVALIAÇÃO DE PACIENTES AMBULATORIAIS EM USO DE ANTICOAGULANTES ORAIS / EVALUATION OF AMBULATORY PATIENTS IN USE OF ORAL ANTICOAGULANTS
As doenças trombóticas constituem um problema de saúde mundial de etiologia multifatorial e multigênica. São caracterizadas por formação aguda de trombos em veias e artérias. Os anticoagulantes orais são usados para criar uma deficiência parcial da forma ativa da vitamina K, um cofator na modificação dos fatores da coagulação vitamina K-depende

40. Ação de polissacarídeos sulfatados de Fucus Vesiculosus na Hemostasia e no sistema complemento
Fucans are a family of sulfated homo and teropolysaccharides respectively, composed mainly of a- (12) and a- (13) linked by L-fucose residues. Properties such as the ability to act as an anti-contraceptive, to reduce cholesterol levels, and to act as an anti-tumor agent are much related. We have focused our attention on the anticoagulant properties, platelet

42. Fatal aldicarb intoxication in dogs and cats: study of post mortem macroscopic alterations and toxicological diagnosis using thin-layer chromatography in samples of stomach content / Intoxicação por aldicarb ("chumbinho") em cães e gatos: estudo das alterações post mortem macroscópicas e diagnóstico toxicológico por meio da cromatografia em camada delgada em amostras de conteúdo estomacal
Pesticides are the main cause of poisoning in human beings and in wild and domestic animals. Preliminary data suggest that the carbamate insecticide aldicarb, illegally sold in São Paulo city as rat poison, has also been used for intentional poisoning of dogs and cats.

43. Evaluation of the marker of hypercoagulability prothrombin fragment F 1+2 in patients with mechanical or biological heart valve prostheses
OBJECTIVE: To investigate whether patients with heart valve prostheses and similar International Normalized Ratios (INR) have the same level of protection against thromboembolic events, that is, whether the anticoagulation intensity is related to the intensity of hypercoagulability supression. METHODS: INR and plasma levels of prothrombin fragment 1+2 (F1+2)

44. Assessment of Thromboembolism After the Cox-Maze Procedure for Chronic Atrial Fibrillation Secondary to Mitral Valve Lesion
OBJECTIVE: To assess the occurrence of late thromboembolism after surgical repair of chronic atrial fibrillation (AF) simultaneously with repair of mitral valve using the Cox-Maze procedure. METHODS: 69 patients underwent Cox 3 procedure, with no cryoablation simultaneously with mitral valvuloplasty or prosthesis. Mean age was 49.9±13.2 years. Mean follow-u

45. Cataleptic postures in thalamic hemorrhage: case report
We report a case of catalepsy associated with thalamic hemorrhage. A 72 year-old hypertensive woman had acute onset of right-sided weakness and speech disturbances. She was on anticoagulants because of aortic valve replacement. When postures were imposed, the patient maintained the left upper limb raised for several minutes, even in uncomfortable or bizarre

47. Effect of collection, transport, processing and storage of blood specimens on the activity of lysosomal enzymes in plasma and leukocytes
This study was designed to evaluate the effect of different conditions of collection, transport and storage on the quality of blood samples from normal individuals in terms of the activity of the enzymes ß-glucuronidase, total hexosaminidase, hexosaminidase A, arylsulfatase A and ß-galactosidase. The enzyme activities were not affected by the different mat

48. Cardiac valve prostheses, anticoagulation, and pregnancy.
The course of 76 pregnancies is reported in 51 women who became pregnant after replacement of one or more heart valves. Age at conception ranged from 17 to 39 years (mean 25). There have been 71 deliveries and five women are still pregnant at the time of writing. In the 71 pregnancies, oral anticoagulants were given during 53, heparin during five, and no ant
