Inhibitory effect of tritoqualine on activation of latent polymorphonuclear leukocyte collagenase

Treatment of rats with histamine releaser compound 48/80 caused changes in blood leukocyte populations. An increased number of PMN-leukocytes was observed. Tritoqualine only modestly reduced the number of granulocytes. In animals treated with compound 48/80 an activation of PMN-leukocyte latent collagenase of up to 80% was observed. This activation was partially inhibited (about 40%) in animals pretreated with tritoqualine. The results presented suggest that the beneficial effect of tritoqualine in allergic diseases may be in part connected with an indirect inhibition of collagenase activity.     

The role of calcium ions and inositol phospholipids in platelet activation]

The present state of knowledge on the importance of calcium ions and inositol phospholipids in the metabolic changes associated with early stages of platelet activation is outlined, with stress laid in the biochemical mechanisms of intracellular rise of calcium ion concentration. The metabolism of inositol phospholipids is briefly discussed stressing the importance of the metabolites of these phospholipids--1,2-diacylglycerol and 1,4,5-inositol triphosphate which are of key importance in the transfer of information between platelet membrane and intracellular structures.     

Serological conflict: relation between antibody titer, Liley's zone and the condition of the fetus and newborn infant]

On the basis of analysis of 128 cases of serological incompatibility it was found that antibodies to Rh in titres of 1/8 or less constituted a good prognostic factor, and without evidence of fetal distress in USG examination this was not an indication to treatment undertaking. If the titre is from 1/16 to 1/128 the prognosis is worse and the degree of fetal haemolytic disease risk may be estimated on the basis of USG and Liley's zone. The prognosis is very bad in case of titre exceeding 1/128 and high Liley's zone, and without effective treatment of haemolytic disease in fetal life only few fetuses survive.     

Long-term results of treatment for articular calcaneus fractures with Westhues method]

In this paper the authors evaluate the long-term results of treatment for articular calcaneus fractures with Westhues method. This evaluation is performed with regard to triple measurement of B?hler's angle value and to subjective criteria. The clinical material from years 1985-2002 consists of 47 patients aged between 24 and 56 years (mean age 32 years) with articular calcaneus fractures--namely, 41 male patients (87.2%) and 6 female patients (12.8%). The follow-up examination was performed in 24 patients (51% of all patients), namely, in 23 male patients (48.8%) and in one female patient (2.2%). Minimum follow-up time was 12 months and maximum was 9 years. Acquired results suggest that Westhues method restores normal B?hler's angle value only in tongue-type calcaneous fractures.     

Results of treating pseudarthrosis and leg bone defects caused by osteitis]

The results of treatment of 17 patients--8 cases of leg bones defect due to osteitis and 9 cases of leg pseudoarthrosis has been presented. The osteosynthesis of the fragments was done with the use of Zespol fixator. In 14 patients the lesion has healed and satisfactory function of the extremity was restored.     

Microsomatoagnosia: whole body schema illusion as part of an epileptic aura

We report a patient who presented with a whole body microsomatoagnosia as part of an epileptic aura. We postulate that this rare phenomenon argues in favor of the existence of a whole body integrative neuronal network which mediates the bodily awareness.     

Retinal detachment in pseudophakia

Retinal detachment in an aphakic eye is a grave therapeutical problem. There exists some fears that cataract extraction with implantation of an artificial lens may increase the number of these complications. Three hundred and seventy cases of cataract extraction with implantation of an artificial lens performed in our department were analysed from the point of view of the incidence of retinal detachment. The cataract was extracted extra- and intracapsularly and the artificial lens was implanted in the anterior as well as in the posterior chamber. During the period of observation--4 months to 3 years--it was established that the number of the retinal detachment in pseudophakia was not larger than in aphakic eyes without implant.
