The three-dimensional ultrastructure of human tendons has been studied. Epitenon and peritenon consist of a dense network of longitudinal, oblique and transversal collagen fibrils crossing the tendon fibres. The internal structure of tendon fibres is also complex. The collagen fibrils are oriented not only longitudinally but also transversely and(More)
We aimed to determine the distribution of the ABO and Rh blood groups in 832 patients with a tendon rupture. Among these, the frequency of blood group O (52.8%) was significantly higher than in the general population of Hungary (31.1%) and the frequency of group A was significantly lower. Of the 83 cases of multiple ruptures or re-rupture, 57 patients(More)
The dry mass concentration and collagen fiber morphology of intact, as well as of degenerated and ruptured human Achilles, biceps brachii, extensor pollicis longus and quadriceps tendons, were determined by using the interference microscopical technique. The variation in the collagen fiber thickness was demonstrated in different intact tendons, the fibers(More)
53 per cent of the 873 cases of subcutaneous (spontaneous) tendon ruptures, treated in the National Institute of Traumatology belonged to the blood group O, and that was significantly higher than in the healthy population (31.1 per cent) of Hungary. The ratio of the tendon rupture patients belonging to the blood group A was significantly lower (27.1 per(More)
Authors have investigated the ultrastructural morphology of transformation of homologous human tendon transplants. Tenoblasts and mast cells were found next to collagenous fibres originating in the transplant and disintegrating in the voluminous ground substance. The formation of new collagen tissue was of different grades; areas of only a few fibres and(More)
The authors have studied the enzymhistochemical and ultrastructural pictures of tenocytes of adult human tendons. High succinate dehydrogenase, cytochrome oxidase, TPN-diaphorase, lactate dehydrogenase and glucose-6-phosphate dehydrogenase activity were found, as indicated both oxidativ, anaerobic and pentose-phosphate shung activity. Phosphorylase and(More)
To assess socio-demographic and smoking-related correlates of e-cigarette and alternative tobacco products (ATPs) use in a multi-ethnic group of adolescents in Tîrgu Mures, Romania. The cross-sectional study included 1835 high school students from Tirgu Mures, Romania. Socio-demographic variables and data about smoking and e-cigarettes and ATP use were(More)
Introduction Although web-based, multimedia smoking prevention programs have been tested in several high-income countries, their efficacy in Central and Eastern Europe is unknown. The aim of this trial was to assess the short-term effects of ASPIRA, among Romanian and Hungarian speaking ninth graders in Tirgu Mures, Romania. ASPIRA is the Romanian acronym(More)
