Elevated plasma gastrin, CEA, and CA 19-9 levels decrease after colorectal cancer resection.
BACKGROUND AND AIMS: Gastrin stimulates mucosal growth of much of the gastrointestinal tract and has also been implicated in promoting growth of colonic tumors, but its role in colorectal carcinogenesis remains controversial. This study determined fasting serum gastrin levels before and after surgery for colorectal cancer (CRC) and the relationship to the clinical stage of the disease to investigate it possible prognostic role. PATIENTS AND METHODS: Fasting radioimmunoassay gastrin, CA 19-9, and CEA levels were measured before and after surgery for CRC. Helicobacter pylori status was also assessed since it causes significant hypergastrinemia. RESULTS: Mean fasting plasma gastrin level was significantly higher in CRC patients than in controls before surgery but not 59 days after surgery. Mean CEA and CA 19-9 levels were significantly higher in patients with CRC before surgery than after tumor resection. There was a significant positive correlation between the plasma gastrin, CEA, and CA 19-9 levels and the CRC stage (Dukes' classification). CONCLUSION: The significance of gastrin as a marker for diagnosis or prognostic purposes in colorectal cancer needs to be further examined.

[Liver tuberculosis].
The case of rare localization of extrapulmonary tuberculosis--isolated tuberculoma of the liver--was described. The tumor was found accidentally, during abdominal ultrasound for benign prostatic enlargement. Computed enhanced tomography didn't explain the character of the tumor, so percutaneous thin-needle biopsy was performed. Preliminary histological report suggested primary liver cancer. Patient was operated on, tumor was removed with the margin of the healthy liver tissue. Histological examination of the specimen revealed the nature of the tumor. Diagnosed liver tuberculoma is usually treated without surgery.

Circadian serum levels of dehydroepiandrosterone sulphate in postmenopausal asthmatic women before and after long-term hormone replacement.
OBJECTIVE: To assess mean 24-h serum concentrations of dehydroepianrosterone (DHEAS) in postmenopausal women with asthma before and after hormone replacement therapy (HRT). METHODS: Studies were performed in 55 asthmatic and 20 healthy postmenopausal women aged 48-60 before HRT and after 6 months of transdermal 17b-estradiol (E2) and medroxyprogesterone acetate treatment (cyclical method). Serum DHEAS concentrations were assessed with the use of RIA method. RESULTS: In the group of postmenopausal asthmatic women treated with glucocorticoids the mean 24 h DHEAS serum levels were lower than in a similar group not treated with glucocorticoids and a control group of healthy postmenopausal women. However, in both groups of asthmatic women (e.g. glucocorticoid treated and untreated) a significant increase of mean daily DHEAS levels after 6 months of HRT was observed. The hormone concentrations did not change in control group. CONCLUSIONS: Postmenopausal asthmatic women show diminished circadian dehydroepiandrosterone sulphate serum concentrations irrespective whether they were treated with glucocorticoids or not. However, after 6 months of hormonal replacement therapy in these groups increased levels of DHEA were found.

[KOMPOR--Computer system for perinatal surveillance. I. System description].
The computer system of perinatal surveillance--KOMPOR-build by OBREAM-TEMED in Zabrze is described. This system enable to collect the personal data of patients, obstetrical anamnesis as well as very precise analysis "on line" of cardiotocographic records.

Relative calibration of a well type isotope calibrator for brachytherapy sources.
The manuscript outlines the results of a quick procedure for relative calibration of a well type Isotope Calibrator for brachytherapy sources. It is demonstrated that accuracy better than 5% is attainable. Some practical considerations with the possible pitfalls in the procedure are discussed.

[Risk of alloimmunization in the granulocyte concentrate recipient].
Forty five patients with diffused peritonitis, complicated with septic shock and neutropenia, have been analysed. Granulocyte concentrate has been administered to 25 patients with negative results of tests detecting lymphocytotoxic and leuko-agglutinin antibodies. Such antibodies have been detected in 35.5% of all patients. These patients have not received granulocyte concentrate. During a 20-day follow up period, antibodies have been produced in 20% of granulocyte concentrate recipients. No signs of alloimmunisation have been noted in 49% of patients with severe peritonitis during the whole follow up period. Non-hemolytic symptoms after transfusions have been seen in 40% of granulocyte recipients and accompanied 16% of all transfusions. No correlation with the symptoms of alloimmunisation was noted.
