Assessment of aprotinin influence on periodontal clinical status and matrix metalloproteinases 1, 2 and their tissue inhibitors saliva concentrations in patients with chronic periodontitis.

PURPOSE: Assessment of the effect of treatment with aprotinin-containing drug on the clinical status of the periodontal tissue and on the concentrations of metalloproteinases released in the course of periodontitis (MMP-1, MMP-2) as well as their tissue inhibitors (TIMP-1 and TIMP-2) in the saliva of patients with chronic periodontitis (CP). MATERIAL/METHODS: The study involved 25 subjects with CP (39-68 years), including 16 women and 9 men. The patients were prescribed aprotinin preparation to be taken for 2 weeks. The control group (C) involved 14 healthy subjects (41-65 years), including 10 women and 4 men. Two periodontal indices were assessed: the approximal plaque index (API) and bleeding on probing index (BOP). Periodontal pocket depth and clinical attachment level were also evaluated. The concentrations of MMP-1 and MMP-2 as well as TIMP-1 and TIMP-2 were determined by the ELISA method. RESULTS: The mean salivary MMP-1 concentration in patients with CP was significantly higher before and after treatment, as compared to healthy subjects. The mean salivary MMP-2 concentration in CP patients at baseline was also higher as compared to the C group and increased after treatment. The mean salivary TIMP-1 and TIMP-2 concentration in CP patients was higher as compared to C group and increased after treatment. CONCLUSIONS: Since the mean MMPs levels were found to be growing it can be assumed that aprotinin has no significant effect on the regulation of MMPs in the saliva of CP patients. It thus seems that aprotinin application after scaling has no additional therapeutic effect.

Assessment of salivary levels of the chosen exoglycosidases in patients with aggressive periodontitis after treatment with doxycycline.

PURPOSE: The aim of the study was the clinical assessment of the periodontium in patients with aggressive periodontitis (AP) after treatment with doxycycline hyclate. Moreover, an attempt was made to evaluate the effect of the treatment on the salivary concentrations of beta-glucuronidase, HEX, HEX A and HEX B in AP patients. MATERIAL AND METHODS: Sixteen patients with aggressive periodontitis, aged 28-45 years, were enrolled in the study. The patients were treated with a doxycycline hyclate preparation (Periostat) for 2 months at a dose of 20 mg twice a day. The clinical examination was performed twice, directly prior to pharmacological treatment and after its termination. The following clinical parameters were evaluated: the plaque index (PI), the sulcus bleeding index (SBI), the pocket probing depth (PPD) and the clinical attachment level (CAL). Biochemical determination of beta-glucuronidase, HEX, HEX A and HEX B concentrations in non-stimulated saliva was performed before and after treatment. RESULTS: In AP patients, the values of PI, SBI and CAL before and after treatment were comparable. The mean pocket probing depth before treatment was 3.5 mm, which decreased significantly after treatment (3.2 mm). The values expressed as pKat/kg protein for specific enzymatic activities of HEX, HEX A, HEX B and beta-glucuronidase in the saliva of AP patients before and after doxycycline treatment were similar. CONCLUSIONS: A 2-month treatment with doxycycline is too short to obtain clinical changes. Although the assessment of the activity of such enzymes as beta-glucuronidase, HEX, HEX A and HEX B in the saliva of AP patients allows detection of periodontal inflammation, it cannot be used to determine the risk of its development and therefore has no practical significance.

Efficacy of local treatment with chlorhexidine gluconate drugs on the clinical status of periodontium in chronic periodontitis patients.

PURPOSE: Chlorhexidine gluconate is a relatively commonly used chemotherapeutic in the treatment of periodontitis (P), exhibiting antimicrobial capabilities against Gram-negative and Gram-positive bacteria, and fungi. This compound is a component of various preparations for topical use in the form of solutions for mouthrinsing or peri-irrigation, gels, varnishes, chips and even chewing gums. The aim of the study was the clinical evaluation of periodontium after treatment with one of the drugs containing chlorhexidine gluconate (Corsodyl) as compared to professional tooth cleaning in patients with chronic periodontitis. MATERAL AND METHODS: Forty subjects enrolled in the study were divided into four groups, 10 in each group, according to the mode of treatment (Corsodyl rinse, Corsodyl gel, Corsodyl gel + surgical dressing, scaling). RESULTS: The greatest differences between baseline and follow-up examinations were observed in the group where surgical dressing was applied in addition to Corsodyl gel and in the group treated with scaling. CONCLUSIONS: Chlorhexidine gluconate should be more frequently used as a drug adjunct to classic periodontal therapy, especially in the forms allowing its direct application to the periodontal pockets.

[Organ changes in experimental strongyloidosis of rabbits provoked by Strongyloides papillosus]. / Zmiany narzadowe w doswiadczalnej wegorczycy kólika wywolane inwazja Srongyloides papillosus.

Strongyloidosis was induced by percutaneous injection of rabbits; then organ changes were tested. It has been found that Strongyloides papillosus evoked changes in intestine, liver, kidney and lung. No notable changes were found in heart, spleen and suprarenal gland. These changes may be provoked not only directly by the presence of these parasites but also by the products of metabolism of S. papillosus.

[Necrosis of the bone marrow]. / Martwica szpiku kostnego.

The authors analyzed the incidence of necrosis of the bone marrow in nonselected autopsy material. The studies included 419 cases of various disease types. Necrosis of the bone marrow was found in 83 cases (19.8%). It was most frequently observed in patients with neoplastic disease of the hematopoietic and lymphatic systems (26.3%) and malignant neoplasms of different origin (21.9%). In 40% cases necrosis of the bone marrow were accompanied by neoplastic metastases into the hematopoietic tissue, and thrombotic changes in the blood vessels occurred in 22.9% of these cases. Our results point to a fairly frequent occurrence of necrosis of the bone marrow, especially in the course of neoplastic disease.

[Lymphocytic aggregations in the bone marrow: their occurrence and morphologic analysis]. / Guzki limfatyczne szpiku kostnego: wystepowanie i ocena morfologiczna.

We analyzed the morphology and incidence of aggregations of mature lymphocytes of the bone marrow in the autopsy material of 425 cases excluding disorders of the hematopoietic and lymphatic systems. We found that lymphocytic aggregations occurred in 21.1% cases. There were two morphologic types of lymphocytic aggregations of the bone marrow, namely lymphoid follicles and infiltrates. It was shown that the incidence of lymphoid nodules of the bone marrow increased with age and that the structures were more frequent in women. We pointed to the significance of lymphocytic aggregations presence in the bone marrow in differentiating with malignant infiltrations of the lymphatic system involving the bone marrow.

[Effect of alcohol on the development of biochemical and morphologic findings of liver damage in the rabbit]. / Experimentelle Untersuchungen über den Einfluss des Alkohols auf die Entwicklung der biochemischen und morphologischen Befunde einer Leberschädigung beim Kaninchen.

Ethanol 48% was applied to the experimental model in 3 examined groups of rabbits in different periods of administration and differentiated daily doses on order to investigate the influence of ethanol upon the formation of morphological and biochemical indices of the liver lesion. Biochemical investigations were carried out on 3 and 7 day of the experiment and repeated at week by intervalls. All the animals were dissected and morphological examinations of the liver were carried out. Total analysis of the results obtained of the biochemical and morphological examinations of the liver in 3 analysed groups of animals proved that the biochemical index of postalcoholic lesion of the liver was a rise in guanase activity, and not in activity aminotransferases. In the investigations of fat balance, however the increase of triglycerides and cholesterol was observed. Morphological examinations showed post-alcoholic lesions of the liver, especially intensified in animals under longlasting alcohol influence, but in reducted doses.

The effect of repeated BCG vaccine administration associated with surgery upon the growth of lung metastases in rats with transplantable Morris 5123 hepatoma.

Eighty four male Buffalo rats bearing transplantable Morris 5123 hepatoma were used for the experiment. Half of the animals were given into the tumor BCG vaccine (final dose 2.2 X 10(6) living mycobacteria), the other 42 rats after BCG underwent surgical removal of the hind leg together with the tumor. Though the immunotherapy reduced the size of lung metastases of the tumor it did not, however diminish the survival rate of the animals. Multiple BCG doses associated with the surgical procedure prevented dissemination of the tumor cells and prolonged the survival of rats up to the 100th day of the follow-up.
