The cardio-vascular response during exercise in athletes

Summary In an exercise test of 160 w intensity, accomplished by 16 athletes, a comparative study was carried out on the following heart rate and arterial pressure indices: total cardiac work cost/w, total cardiac recovery cost/w, the ratio of the former to the latter, cardiac work cost above rest/w, cardiac recovery cost above rest and the ratio of the former to the latter, the cardiac work cost above rest/w in the last minute, cardiac recovery cost, the sum of P_1,2,3 and P_{av. 1,2,3}, the ratio of increase of systolic pressure during work to the number of watts performed, the ratio of this pressure increase to the heart rate increase, the ratio of differential pressure during work to: the heart rate in the 10. min of work, increase in the heart rate during work and number of watts achieved.     

Contralateral surgery in palpebral ptosis after common oculomotor nerve paresis

Congenital palpebral ptosis is a disease which make problems about surgery timing and surgical method used. A child, three years old, presents partial palpebral ptosis at left eye after congenital paresis of the oculomotor common nerve. Ocular statistical exam underlines one deviation by ten degrees and dorsal vergence by fifteen degrees at left eye. After covering the right eye, the left eye assumes fixation and the upper eyelid elevates. On practise liberality of the right superior muscle at the right eye (Faden method and recoil by 5 mm), which establishes the disparition of the left eye deviation and of the ptosis. Orthoptic exam must direct the decision about the surgical method in these situations.     

The blood enzymatic antioxidative potential in bronchial asthma patients

This study aims at assessing the ability of asthma patients to defend themselves against the noxious effects of oxidative stress, known being the inflammatory nature of this disorder. As the anti-radical defence ability of the body is reflected by the antioxidative potential of blood and tissues, our study was based on the determination of the activity of superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx) and CAT/SOD and GPx/SOD ratios in the blood. Except for SOD, the activity of which was lower in asthma patients by -34.08%, CAT and GPx had values increased by +32.18%, respectively, with a resulting increase of CAT/SOD and GPx/SOD ratios. Our data, demonstrating a change in per-oxidants/antioxidants balance in favour of the first ones, seem to suggest that in the treatment of bronchial asthma the association of some compounds with antioxidants effects would be beneficial.     

The electroencephalographic aspects in stress epistaxis

The nasal haemorrhage is a symptom whose significance is seldom completely investigated. In this paper we present the results that we have obtained in two groups of patients: a pediatric population who presented for repeated episodes of nasal haemorrhage and a group of first trimester pregnant women who also have noticed the appearance of this symptom. Beside the clinical examination, a paraclinical assessment has been performed, which included a laboratory profile (hematology and biochemistry) and electroencephalography (EEG), in which we found significant changes. We conclude that EEG is a valuable investigation technique for diagnosis and monitoring purposes in nasal hemorrhage. Also, the clinical management of the stress-related nasal hemorrhage must address multiple issues for becoming efficient.     

Vanadium derivatives--a new source of antidiabetic drugs

Vanadium, a transitional element belonging to Vb group is wide-spread both in vegetal and animal world. Although known by more a hundred years ago only in 1985 its hypoglycaemic properties were established. Recent research shown that the hypoglycaemic properties and the toxicity are influenced both by vanadium valence state and organic moiety that is binding it.     

Periodontitis, a risk factor for cardiovascular diseases?

Exist a statistically significant association between a diagnosis of coronary heart disease and certain oral health parameters. These parameters are independent and more strongly associated with coronary heart disease than were recognized risk factors, such as serum cholesterol levels, body mass index, diabetes and smoking status. The correlation between serum and salivary cholesterol concentration and the role of salivary lipids in oral health have been poorly characterized. Lipids in saliva are mostly glandular in origin, through some may diffuse diffuse directly from the serum. The surface of the enamel (in case of dietary fat which have an cariostatic effect) is protected against demineralization by a mixture of salivary lipids and proteins. Salivary lipids may have anucleating role in the early mineralization of the dental plaque. The prevalence of periodontal disease may be increased in patients with atherosclerosis, and dental and periodontal infections have been shown to be associated with occurrence of acute and chronic coronary heart disease. Among the known risk factors of atherosclerosis, high serum lipid levels, especially cholesterol may be important with regard to periodontal health.     

Individual pressure tolerance--a "target" pressure?

In literature there are many meanings for the limit between normal and pathological intraocular pressure: "normative pressure", "critic pressure", "individual tolerance pressure" and "target pressure". The aim of this paper is to demonstrate that these terms are synonymous.     

Changes in the craniomandibular relations of acromegaly patients

The dishomeostazical theory (etiopathogenic integrative concept) allows an ample and complex vue on the stomatognathic system dysfunctional syndrome, because it begins from the perception of the stomatognathic system (SS) as a whole in which the alteration of each element can induce the disfunction of the entire system. The purpose of this study is to demonstrate that the neuroendocrine suprasystemic factor (STH hypersecretion on adult organism) disturbs every element of the SS and induces an important alteration of the fundamental cranio-mandibular relations.     

The causes of gingival overgrowth

Gingival overgrowth includes a series of diseases with many clinical appearances. The pathological mechanisms being obscure there were used many terms for defining it. Thus, "gingival hyperplasia" and "gingival hypertrophy" were the definitions used to define this pathology. Therefore, the term of "gingival overgrowth" replaced in last decades the above two terms. This article have the goal of trying a classification of the entities forming the large family of gingival overgrowth.     

The concordance and discordance of cardiovascular risk factors in a group of twin children

The cross-sectional study of epidemiological screening type has permitted to evaluate some cardiovascular risk factors in two groups of monozygotic (MZ) and dizygotic (DZ) twins born between 1975-1990, in the town of Ia?i. In the 89 MZ pairs and 112 DZ pairs, certain constitutional and behavioural cardiovascular risk factors have presented values of prevalence with statistical signification (p < 0.05) in terms of their age, sex, the urbanisation time and the educational level of their parents. In risk factors existence or absence to both of the twins have put into evidence, to the MZ, most enhanced values of concordance as regards: overweight (66.6%), excessive consumption of salt (56.9%), food with atherogenic risk (50.9%). The concordance values have been less in DZ compared to MZ concerning all the risk factors excepting compartmental type A (77.7%). By analysing the concordance variants, an preponderant influence of the environment has been noted in the studied MZ and heredity and environment influence in DZ. By measuring the arterial blood pressure values at the twins and the twins parents, a prevalence of the essential arterial hypertension is noticed to both of the twins, 6.2% in MZ pairs and 6.9% in DZ ones.
