[Ultrasonographic examination in the follow-up of patients after kidney transplantation].

The authors followed-up in 1988-1994 a total of 134 patients after renal transplantation by ultrasonographic examinations in the B mode, Doppler frequency analysis and coloured Doppler mapping. They summarize the basic sonographic pictures during a normal development after transplantation and in case of surgical and non-surgical complications. They evaluate sonography as the basic examination method which is not quite specific for different complications but makes it possible to detect them in the initial stage and to indicate in time further examinations and treatment.

[Typology characteristics of preschool-age gypsy children in the Czech Republic].

The study assesses the somatotype (using the method of Heath-Carter, 1967) and its changes in 439 pre-school 3-7 years old Gypsy children and compares results with the situation in 348 non-Gypsy children. A change in somatotype with age and a typical dominance of the mesomorphic component in the pre-school age in both Gypsy and non-Gypsy children has been confirmed. This is in agreement with studies on non-Gypsy children. The above findings and the fact that differences in somatotype between ethnic groups are smaller than those between sexes show that the somatotype and its developmental tendencies in pre-school age are almost identical in Gypsy and non-Gypsy children.

[Pathologico-morphologic changes in the digestive system in rabid foxes].

Pathologico-morphological changes in the digestive tract were investigated in fifty naturally infected common foxes (Vulpes vulpes crucigera). Nineteen animals were found to suffer from mild cachexia, 31 animals suffered from complete cachexia. Erosions were observed in the mucosa of oral cavities of 21 foxes. Traumatic injuries appeared in the teeth of 11 animals. One case of swollen and hyperaemic tongue was described; in three cases there occurred sialo-adenitis. A mild degree of inflammation was recorded in the gullet in three animals. Fifteen animals had empty stomachs, thirty-five animals had atypical food or foreign bodies in the stomach contents; simple hyperaemia was recorded 18 times, acute catarrhal gastritis 19 times and haemorrhagic gastritis was observed in two cases. Acute catarrhal enteritis was found in six cases, haemorrhagic enteritis in one case.

[Typing of districts for a study of the health status of the Czechoslovak population].

The Institute of Social Medicine and Organization of Health Services is conducting at present the so far most extensive survey of the health status of the population in a sample comprising almost 20,000 subjects, i.e. subjects taking advantage of health services, as well as those who do not use the health services either because they are healthy or assume that they are healthy, or possibly for other reasons. For this survey a population sample is used which was previously used by the Federal Statistical Office for a survey of the class and social structure in the CSSR in 1984. This sample which is too large for our work had to be reduced. This reduction was made by selecting from the original sample, which comprised the entire territory of Czechoslovakia, only some districts where the survey was made. In order to make the selected districts representative for the entire territory of the country, we elaborated a typology of districts which contains demographic, economic, social and oecological parameters. For elaboration of the typology cluster analysi was used.

[Survival of rabies virus under external conditions].

The survival of the street rabies virus in a 10% suspension, prepared from the salivary gland of a naturally infected fox, was studied under various conditions. A bioassay and titration on mice were used for the identification of the virus in different intervals. The heat inactivation of the virus in a suspension kept in a test tube at the temperatures of 20 degrees C and 37 degrees C was performed in two stages. The rapid reduction of the titre within 24 hours was followed by a slower decrease, reaching total inactivation after 96 hours at both temperatures. When the virus was tested by means of the contamination of various substrates (glass, metal sheet, plant leaf) with 0.1 ml of infection suspension in a thin layer, the longest survival of the virus was recorded at the temperature of 5 degrees C--144 hours. At the temperature of 20 to 21 degrees C the virus kept its activity on the glass and plant leaf for 24 hours and on the metal sheet for 48 hours although the applied drops looked like having dried. The temperature of 30 degrees C combined with intensive sunshine devitalized the virus within 1.5 hours, whereas without sunshine the virus still remained active, at the temperature of 30 degrees C, after 20 hours.

[Excretion of the rabies virus in foxes after experimental infection].

Fourteen foxes (Vulpes vulpes crucigera) were experimentally infected with rabies. The excretion of the virus in saliva was subjected to qualitative study. Three different street strains isolated in the territory of the Czech Socialist Republic were used for the intramuscular infection at the doses of 50 or 5000 MICLD50. The presence of the virus in saliva was demonstrated in 12 animals (86%). Post-mortal examination revealed the virus in the salivary gland of 13 animals (93%). The virus started to be excreted in saliva maximally two days before the onset of the clinical signs of the disease and it lasted maximally six days. The affinity of the virus for the salivary gland was related to the strain used, and increased when a lower infection dose had been administered.

[The prevention and therapy of fascioloidiasis using bithionol sulfoxide].

The elimination of the sources of invasion, i. e. hay and forage coming from the infested biotopes, combined with the administration of bithionol sulphoxide, resulted in a reduction of the invasion of cattle by Fascioloides magna from 21.1 to 3.2% within two years. The Czechoslovak-produced bithionol sulphoxide, administered at a rate of 40 to 50 mg per kg body weight as medicated feed, showed 100% effectiveness. At doses higher than 30 mg per kg body weight, the protective period should be prolonged to three or four weeks.

[Effectiveness of various barbiturates in chickens of different ages].

Phenobarbital, allobarbital, and pentobarbital in the doses of 40 and 80 mg per 1 kg body mass were applied intramuscularly to groups of the cockerels of the WL breed at the age of two days, one, two, and six weeks (each group had ten birds) and to eight-week-old WL cockerels in groups of five birds. The methods of clinical observation and repeated determination of the response of the animals to sonic stimuli and contact stimuli, and the evaluation of the quality of some reflexes (particularly the spontaneous position of the body and the correction of the lateral position) were used for the study of suppression evoked by the applied barbiturates. Sleep occurred first after the application of pentobarbital (sooner in younger age groups). The latest beginning of sleep was observed after phenobarbital; in the latter case, sleep was hard to evaluate because it was not very deep. The time of sleep had the longest duration after allobarbital (only in the eight-week-old sleep was longer after pentobarbital), and the shortest after phenobarbital; there were also differences in the duration of sleep between the age groups of birds. The pentobarbital dose of 80 mg kg-1 of body mass killed birds in the three youngest age groups )in the two-day-old it killed nine of ten birds, in the one-week-old eight of ten birds, and in the two-week-old two of ten birds). The differences in the effectiveness of the applied barbiturates in two doses per unit of body mass were related to the age of the animals, even in the cases of the shortest age intervals between individual groups. Very high interspecies differences ensue from a comparison with the doses of these barbiturates usually applied to man.
