[Immunochemical determination of immunoglobulins and lysozyme in normal human saliva - principal assay technics].

We have studied a method to determine the concentrations of low level of immunoglobulins and lysozyme in saliva. The concentration of IgG, IgA and IgM in human whole saliva were measured by fluorimetric method and the concentration of lysozyme by turbidimetric method. The results of our study in 18 normal subjects (15 females and 3 males), have showed the geometric mean concentration (microgram/ml) IgG 5,1; IgA 177; IgM 2,6 and lysozyme 117.

[A method for erythrocyte filtration].

Erythrocyte deformability is one of the most important factors on determining blood viscosity. Many microcirculation damages are caused by alteration of viscosity. We propose a method for evaluate erythrocyte filtration using Nucleopore membranes, to study erythrocyte deformability. Normal ranges are calculated in young healthy subjects. Mean filtration time is determined on 5 filtrations for every subject. Filtration rate is expressed by sec/ml and correlated whit haematocrit. The method is not easily utilizable, but it can be useful in the knowledge of the role of the erythrocyte deformability in the altered microcirculation.

Pain and anxiety control in Down syndrome.

The most recent pain and anxiety control techniques employed in patients with Down syndrome are described in relation to how cooperative the patient is and what assessment is made of his or her general condition. The growing deinstitutionalization of these patients and the growing social opportunities for them are matched by an increasing demand for dental treatment. Down syndrome is thus one of the disabilities with which the dentist is most likely to come into contact in his own surgery. Pain control is one of the keys to building the relationship between physician and patient and obtaining patient compliance in the conviction that only regular controls can maintain the oral health of these patients. A local anaesthetic, combined when possible with psychological techniques, remains the approach of choice and only a level of compliance that is really wanting or the need to carry out numerous operations in a single session should lead the dentist to choose conscious sedation or a general anaesthetic. The choice of technique, however, should take into account any systemic disease present, such as congenital heart and neurological diseases, bearing in mind that conscious or deep sedation and general anaesthesia should only be adopted in a hospital environment and require the presence of an anaesthesiologist.

[Anomalies of enamel structure: description of a clinical case].

The anomalies of dental structure are quite common in pediatric dentistry; these anomalies can involve separately or in the same time enamel, dentin or cementum and they are due to many factors acting during odontogenesis and istogenesis. The Authors analyse these abnormalities and describe a personal case.
