Reduction of bioavailability and phytotoxicity effect of cadmium in soil by microbial-induced carbonate precipitation using metabolites of ureolytic bacterium sp. POC9.

The application of ureolytic bacteria for bioremediation of soil contaminated with heavy metals, including cadmium (Cd), allows for the efficient immobilization of heavy metals by precipitation or coprecipitation with carbonates. Microbially-induced carbonate precipitation process may be useful also in the case of the cultivation of crop plants in various agricultural soils with trace but legally permissible Cd concentrations, which may be still uptaken by plants. This study aimed to investigate the influence of soil supplementation with metabolites containing carbonates (MCC) produced by the ureolytic bacterium sp.

[Irrational use of drugs as a source of drug - induced diseases].

The irrational use of medication, by which we understand the administration of drugs for indications where their effectiveness has not been confirmed, the disregard of restrictions and warnings against their use, and the use of drug combinations which do not increase the therapeutic effect but to the contrary increase the risk of adverse drug reactions, is a serious problem encountered in paediatric pharmacotherapy. Each year the centres for monitoring of adverse drug reactions receive many reports, the analysis of which show that the reasons of occurrence of adverse drug reactions after drug administration, are specifically due to irrational use of medications. In order to prevent in an active way the occurrence, of adverse drug reactions following drug administration it is worthwhile to bring to attention the reasons for their occurrence which not infrequently bring about pathological effects.

Simvastatin effects in normo- and hypercholesterolaemic patients with peripheral arterial occlusive disease: a pilot study.

Improvement of endothelial function caused by statin treatment is not related to lowering of the cholesterol levels but results primarily from statin pleiotropic effects. Accordingly, we designed a pilot study in 10 normocholesterolaemic and 10 hypercholesterolaemic patients with peripheral arterial occlusive disease to investigate potential biological effects of statins in relation to their effects on endothelial function. The patients were treated with simvastatin 40 mg/daily for 3 months.

Misoprostol as agonist of IP2 receptor.

Fourteen patients with peripheral vascular disease received 200 microg of misoprostol 3 times a day during one month. The therapy with misoprostol caused clinical and biochemical improvement in all 14 patients. An elongation of pain free and maximum walking distance, shortening of pain duration and increase in arterial blood flow in both calves were observed.

Plasma and urine pharmacokinetics of the dopamine agonist alpha-dihydroergocryptine in patients with hepatic dysfunction.

Objective: The aim of this study was to evaluate the pharmacokinetic behavior of unchanged alpha-dihydroergocryptine (DHEC, Almirid, Desitin Arzneimittel GmbH, Hamburg, Germany, under licence of Polichem S.A., Luxembourg) and total DHEC (unchanged DHEC and pooled metabolites) in plasma and urine in patients with impaired hepatic function, following administration of single oral doses.

[Evaluation of fraxiparine efficacy in the treatment of retinal vein occlusion].

Purpose: To evaluate the efficacy of Fraxiparine in the treatment of central retinal vein occlusion and retinal branch vein occlusion.

Methods: 30 patients were treated. Fraxiparine (Sanofi-Pharma) was injected subcutaneously in doses of 7.

Treatment of peripheral vascular disease with misoprostol (Cytotec): a pilot study.

Misoprostol, the oral analogue of alprostadil, was used to treat 20 patients (aged 40-60 years) with peripheral arterial disease (PAD) according to Fontaine's classification at stages IIa and IIb. All patients received 200 micrograms of misoprostol 3 times a day during a month. The therapy with misoprostol resulted in clinical improvement in all patients.

[The effect of treatment with sulphur water from the spring in Wiesław in Busko-Solec on levels of lipids,the fibrinolytic system and thrombogenic platelet function in patients with arteriosclerosis].

29 patients with arteriosclerosis obliterans and elevated level of cholesterol and/or triglycerides in blood received undiluted sulphur water from the spring Wiesław in Busko-Solec at the dose of 50 ml 3 times a day for 4 weeks. Such a treatment resulted in statistically significant decrease of blood levels of cholesterol, triglycerides and LDL cholesterol. The concentration of HDL cholesterol did not change significantly.

[Misoprostol--oral prostanoid--the first clinical trial for use in patients with peripheral vascular disease].

Misoprostol, the oral analogue of alprostadil was used for the treatment of 20 patients (aged 40-60) with peripheral arterial disease according to Fontaine's classification at stages IIa and IIb (PAD). All patients received 200 micrograms of misoprostol 3 times a day during a month. The therapy with misoprostol resulted in a clinical improvement in all patients.

Multiple fundic gland polyps in duodenal mucosa not associated with colonic polyposis.

One of extracolonic manifestations of Gardner's syndrome and familial adenomatous polyposis (FAP) are fundic gland polyps (FGP) located typically in the gastric body. Rarely FGP develop in the absence of intestinal polyposis. A case of FGP in the duodenal bulb without associated pathological changes in the large bowel has been reported.

L-arginine--substrate for no synthesis--its beneficial effects in therapy of patients with peripheral arterial disease: comparison with placebo-preliminary results.

Intravenous infusions of L-arginine (L-ARG) and placebo (saline) resulted in improvement of clinical assessments, statistically significant after L-ARG but not after saline. Results of laboratory estimations for platelet and fibrynolysis changed significantly following L-ARG infusions but not after infusions of placebo. These data indicate beneficial effects of L-ARG as a therapeutic agent in patients with peripheral arterial obliterative disease (PAOD).

Misoprostol (cytotec) in the treatment of peripheral ischaemic disease.

The stable prostacyclin analogue-iloprost and prostaglandin E1 (Alprostadil) showed a beneficial effect on activated platelets and leukocytes, and thrombocyte and leukocyte vessel interaction and damaged endothelium, improving microvascular perfusion and were useful in treatment of patients with peripheral arterial disease. The 4 weeks therapy with misoprostol caused a clinical improvement in all 14 patients and resulted in vasorelaxation and showed antiplatelet and fibrinolytic effects.

Treatment with L-arginine is likely to stimulate generation of nitric oxide in patients with peripheral arterial obstructive disease.

The impairment of endothelial function in hypercholesterolaemic animals and humans is known to be reversed by intravenous infusions of L-arginine (L-ARG), the precursor of NO. 22 patients with peripheral arterial obstructive disease (PAOD) received L-ARG (60 mmol) as intravenous infusions, each lasting three hours, daily for seven consecutive days. This treatment resulted in elongation of the painfree and maximum walking distances, as well as shortening of the period of time required for pain relief after walking the maximum distance.

[A case of high intestinal obstruction caused by mycotic bezoar of the duodenum].

A case of the mycotic bezoar in the female patient with gastric hypersecretion is reported. The symptoms of the high intestinal obstruction accompanied underlying disease. Bezoar formed of Geotrichum candidum was fragmentated with biopsical forceps of "alligator" type.

Phenazone metabolism during perfusion of isolated guinea pig liver.

After 3 hr of perfusion of isolated guinea pig liver with a medium containing 407 ng/ml of phenazone, the drug concentration in the bile was 1.5 times higher than the initial concentration in the perfusion fluid. This indicates that in addition to phenazone metabolism, liver eliminates the drug by active releasing it to the bile.

Effect of secretin on antipyrine elimination during extracorporeal perfusion of the isolated guinea pig liver.

The aim of these investigations was to elucidate in which part of the bile system (canaliculi or ductules) antipyrine is secreted actively into bile during extracorporeal perfusion of isolated guinea pig liver. Twelve perfusions were performed including 6 control and 6 with secretin. After 1, 2 and 3 hours from the onset of perfusion the perfusion fluid and bile samples were taken for determination of antipyrine concentration.
