Gunshot wound of the lumbar spine]

A case of 20 years old patient with the gunshot injury of the spine was presented. The bullet has stuck in the spinal canal at L3-L4 level causing no neurological disturbances. It was removed in our department gunshot wounds to do this in district hospital. No complication occurred in the postoperative course.     

How reproducible is cutaneous electrogastrography? An in-depth evidence-based study1

AIM: To check on reproducibility of parameters of the cutaneous electrogastrogram registered at a close or a distant time span. METHODS: Twenty-two volunteers recruited by an advertisement (11 females and 11 males, median age 25 years, range: 18-35) underwent three surface electrogastrography examinations of which two were taken on consecutive days and the third one was accomplished at least 2 weeks before or after the two other sessions. The examination involved a 30-min fasted recording, followed by a 90-min postprandial registration after intake of a 394-kcal mixed solid-liquid test meal. RESULTS: Parameters of the electrogastrogram pertaining to the frequency of the gastric slow waves exhibited good to moderate reproducibility, whereas fair reproducibility characterized parameters expected to describe the power of gastric slow waves. With the exception of the difference fed minus fasted power (DeltaDP), in no instance was the medium term reproducibility any worse than the short term one. Categorical data analysis revealed that the relative time share of normogastria postprandially exhibited a better reproducibility than in the fasted period. The Cohen's kappa-value of 0.459 for the DeltaDP for the medium term reproducibility placed this parameter within the range of moderate agreement between repeat examinations. Of the two two-parameter combinations considered, the alliance of the fasted and fed normogastria performed worse than any of those parameters considered alone, whereas a combination of the DeltaDP with the fed-state normogastria revealed a kappa-value amounting to 0.510 for the medium term reproducibility. CONCLUSIONS: The feasibility of some electrogastrographic parameters to convey clinically useful information may be hampered by their fair reproducibility. Recoding of parameters of the cutaneous electrogastrogram from primary continuous to secondary categorical may help achieve a better agreement between repeat examinations.     

Interferonogenic and antiviral effect of extracts from Erodium cicutarium

Extracts from Erodium cicutarium L. Herit were tested for antiviral and interferon inducing properties. Both water extract and methanol extract as well as its fractions were observed to exert antiviral effect in relation to myxoviruses, Herpes virus type 1, Vesicular stomatitis and vaccinia virus. None of these extracts did induce interferon in a suspension of human leukocytes.     

The influence of prolonged clofibrate treatment on the plasma drug concentration and liver NADP-linked enzymes activity

The clofibric acid (CPIB) concentration in the rat blood plasma during 14 days of treatment with clofibrate and after cessation of the treatment, was measured and compared with the changes of some NADP-linked dehydrogenases activity. CPIB rapidly accumulates in the plasma during the first two days of clofibrate administration reaching a maximum concentration of about 0.6 mM. Then a linear decrease of the drug concentration was observed. The second day after clofibrate treatment had been completed, CPIB could no longer be detected in the plasma. Liver malic enzyme activity increased constantly up to the third day after cessation of the treatment. There was a decrease of activity which reached its control level on the 32nd day of the experiment. The variation patterns of hexose monophosphate shunt dehydrogenases activity and liver weight were similar to the changes of malic enzyme activity.     

Microbial transformation of azacarbazoles. I. N-methylation of alpha-, beta-, and gamma-carbolines by Kitasatosporia setae strain

Microbial transformation of selected azacarbazoles, compounds noted for their activity as antitumor agents, conducted with Kitasatosporia setae strain resulted in N-methylation of pyridine nucleus of alpha-, beta- and gamma-carboline molecule. Formed quaternized intermediates were converted in alkaline conditions into corresponding iso-carbolines. The structure of the final products, alpha-, beta- and gamma-iso-carbolines have been established on the basis of spectral data and confirmed by chemical synthesis.     

Synthesis and anticonvulsant properties of some arylsuccinate methylpyridylimides

In reaction of alpha-phenyl, alpha-p-chlorophenyl and alpha-m-chlorophenylsuccinic acid with various aminopyridines, N-pyridyl-substituted succinimides (compounds 1-14) were obtained. These compounds were investigated for their CNS activity. Compounds 1, 2, 5, 6 and 7 displayed anticonvulsant properties in the maximum electroshock test. Compounds 5 and 6 were also active in the pentetrazole test.
