[Clinical significance of serological markers of Helicobacter pylori].

Helicobacter pylori (H. pylori) is a Gram-negative, curved bacillus known since 1983. It is supposed to play role in the pathogenesis of certain gastroduodenic diseases, e.g. non-ulcer dyspepsia (NUD), chronic inflammation, ulcers, etc. Serum samples of 70 patients who were examined for stomach complaints with gastroscopy and those of 22 healthy persons were analysed. The purpose of the study was to evaluate anti-H. pylori IgG, IgM and IgA antibodies using ELISA method. Whether the antibodies can be detected or not, 8 possible variations exist, each of them denoting certain state of infection. These states are not always going parallel with the macroscopic pictures revealed by gastroscopy, but there are some obvious congruences. Results show that serologic examination cannot replace gastroscopy but on the other hand in follow-up tests and examinations as well as in understanding the aetiology of different gastroduodenal diseases it can play an important role.

[Diagnostic value of alkaline phosphatase isoenzymes].

Among the serum enzymes used for diagnostic purposes the alkaline phosphatase (AP) is one of the oldest and the most frequently applied laboratory tests. Increased activity found in the serum is a consequence of certain hepato-biliary disorders, different bone diseases, endocrine syndromes, kidney illnesses and malignant tumors as well. From the study of the pattern of the isoenzymes of the serum-AP information of practical importance may be gained by which many differential-diagnostic problems can be solved. For the clinical-chemical laboratories methods that use electrophoretic separation on different membranes or gels are recommended. Patterns characteristic for different diseases may well be differentiated from normal constellation. AP-isoenzymes help to reveal cholestases at early stages, some disorders of bone metabolism and malignant processes as well.

Acute monosymptomatic aseptic meningitis caused by Toxoplasma gondii.

Acute monosymptomatic aseptic meningitis was observed in a 4 year old male patient. Toxoplasma gondii tachyzoites were detected in Giemsa-stained smears prepared from the CSF. Inoculation of mice gave the same result. The patient was cured after the application of pyrimethamine and sulpha drugs. On basis of the smears, the serological results and data in the literature, a direct infection through the nasal cavity has been assumed.

Isolation, properties and P content of the human brain myosin.

KCl-, and NaCl-myosins were prepared from different parts of the central nervous system (CNS). Throughout these experiments P and lipid contents were higher in NaCl-myosins than in KCl-preparations. Both KCl-, and NaCl-myosins have increased lipid and P contents compared with skeletal muscle myosins. When the specimens were separated by a molecular sieve, it was found by chromatographic technique on Sepharose 4B column that the cerebral and cerebellar myosins were composed of two fractions of different molecular mass while the brain stem and spinal cord myosins revealed only a single peak. The myosin fractions' Ca-ATPase activity could be augmented by rabbit muscle actin. The myosin preparations developed filamentous systems and aggregates which could be shown by scanning electron microscopy. All the CNS-myosin preparations could be phosphorylated; however, they were saturated to a different degree and were influenced by the presence or absence of serotonin. The kinetic studies revealed that the phosphate saturation of the brain stem, cerebellar and cerebral myosins depended on the ATP concentration and incubation time. The alkaline hydrolysates of lipid-free human brain myosin preparations contained amino acid phosphates, P-Arg, P-Lys and P-His in different amounts depending on their sources. In response to a phosphorylating mixture only the amount of P-Arg was elevated in the cerebral myosins, P-Arg and P-His in the brain stem preparations, and P-Arg, P-His and the amounts of unidentified compounds in the cerebellar ones.

[Acute disease conditions and emergency situations in psychiatry].

Beyond a fundamental observation of the characteristics of acute illnesses and emergencies in psychiatry (symptomatology, progression and personality as a pathogenic factor), pathogenic conditions (somatic causes, personality, environment) are described together with typical syndromes and therapeutic principles.
