An original method of endolymphatic therapy with the stimulation of the lymph outflow was developed and used in 108 patients with peritonitis. The dynamics of intoxication parameters was studied during the endolymphatic therapy, indirect electrochemical oxidation of blood, photochemotherapy and traditional treatment. The method proposed has been found to be most efficient. The method of endolymphatic therapy with the lymph stimulation allowed lethality from peritonitis to be decreased to 7.4%. 相似文献

A simple analytical method for ochratoxin A (OTA) determination in grapes is described, using aqueous methanolic extraction, an immunoaffinity column clean-up step and high-performance liquid chromatography with fluorescence detection. Mean recovery was 94% (RSD = 4.0%) with a detection limit of 0.4 ng g-1 and quantification limit of 1.20 ng g-1. Repeatability (r) and reproducibility (R) were 1.17 and 1.34, respectively. OTA determinations were applied to 50 grape samples (23 different varieties) originating from representative regions of Greece. Results showed the presence of OTA in 86% of samples tested (n = 50). Traces were found in 56% of samples but OTA was not detectable in 14% of samples. Traces were also found in 4% of red, organically grown samples. The most contaminated were three samples of red grapes, two from Central Greece (2.69 and 1.41 ng g-1), both table and wine-making grapes. The third sample (1.46 ng g-1), originating from the island of Samos, was used only in wine-making. Mean (1.06 ng g-1) and median (0.76 ng g-1) OTA concentrations in red grapes were slightly higher compared to the mean (0.82 ng g-1) and median (0.65 ng g-1) concentrations in white grape samples. The study shows that the potential risk for a person of 60 kg ranged from 0.9 to 9 ng kg-1 bw day-1 and is dependent on the quantity of grapes consumed daily. 相似文献

Molecular dynamics calculations have been carried out on a model of the LS3 synthetic ion channel in a membrane mimetic environment. In the absence of an external electrostatic field, the LS3 channel, which consists of a bundle of six alpha-helices with sequence Ac-(LSSLLSL)3-CONH2, exhibits large structural fluctuations. However, in the presence of the field, the bundle adopts a well defined coiled-coil structure with an inner pore of water. The observed structural changes induced by the applied field are consistent with the proposed gating mechanism of the ion channel. 相似文献

A 62-year-old woman presented with a 3-week history of obstructive jaundice. Computed tomography of the abdomen showed marked enlargement of the head of the pancreas and a prominent pancreatic body, suggestive of a neoplasm with associated pancreatitis. The peripheral blood showed an increased number of plasma cells accounting for 50% of the leukocytes. Biopsy specimens of the pancreas, liver, and a peritoneal lymph node showed a diffuse infiltrate of typical and atypical plasma cells (50% of which had cytoplasmic IgG-lambda). Serum and urine protein electrophoresis revealed a monoclonal IgG-lambda spike and Bence Jones-lambda protein, respectively. The bone marrow was diffusely infiltrated by plasma cells. To our knowledge, this is the first reported case of a plasma cell leukemia presenting as a pancreatic mass producing extrahepatic biliary obstruction. 相似文献

Biochemical and immunological indices were studied with regard to insulin dose in 321 patients with diabetes mellitus type I. Overdosage of insulin in these patients induced significantly more frequently clinical manifestations of atherosclerosis, marked shifts in lipid spectrum of the serum and in immunological picture. In diabetics on physiological doses of insulin atherosclerosis is a rare finding, lipid spectrum and immunological indices in stable normoglycemia did not differ much from controls. Implication of chronic insulin overdosage in mechanism of atherosclerosis onset is suggested. 相似文献

A 15-year-old girl had bilateral corneal infiltration associated with diabetes insipidus which has been treated for 8 years. The correct diagnosis of histiocytosis X was obtained after histopathological examination. The strict correlation between pathological anatomy and clinical status favoured Hand-Schuller-Christian disease. 相似文献

Addition of calcium ions increased 2- to 3-fold the growth of Saccharomyces carlsbergensis 2I in a minimal glucose-containing medium. The minimal concentration enhancing growth was 25 to 50 mug/ml CaCl2. Other divalent and trivalent cations tested, except for strontium ions, did not duplicate the calcium effect. Actively growing and dividing cells took up 45Ca2+, while resting yeast cells did not. The radiocalcium taken up was incorporated into newly synthesized structural material, presumably into the membrane protein. 相似文献

Nineteen pregnant women with burn areas ranging from 6 to 92% of the total body surface area were treated at the US Army Institute of Surgical Research between 1951 and 1974. A review of these cases led to the following observations and conclusions: 1) Pregnancy does not alter the maternal outcome after thermal injury. 2) Maternal survival is usually accompanied by fetal survival. 3) If the gravida's injury is lethal, the pregnancy will usually terminate spontaneously prior to her death. 4) Obstetric intervention is indicated only in the gravely ill woman whose complications (hypotension, hypoxia, or sepsis) jeopardize the life of the fetus. 5) A better understanding of the complications of major burns and the care available in modern burn units should improve the prognosis for burned pregnant patients. 相似文献

OBJECTIVE: To assess the risk of probe contamination following transvaginal ultrasonography. DESIGN: Prospective cohort study. SETTING: University Infertility Center. PATIENT(S): Women undergoing transvaginal ultrasonography. INTERVENTION(S): One physician obtained 840 consecutive transvaginal ultrasonograms over nine months. Latex condoms were used to cover the probe. Following examination, the condoms were removed and the probe was wiped with a germicidal disposable cloth and left to air dry for 5 minutes. Condoms were filled with water and examined for leaks. MAIN OUTCOME MEASURE(S): Number of perforations and distance from condom tip. RESULT(S): Seventeen (2%) of 840 condoms leaked. The mean distance from the tip to the point of leakage was 10.6 cm +/- 2.8 (mean +/- SD; range, 7-14). Sixty-five percent of the leaks were < or = 10 cm from the tip. In several instances, two leaking condoms were found within a few examinations of each other. No visual contamination of the probe was noted. CONCLUSION(S): Although only 2% of condoms leaked, 65% were at distances that could have led to probe soiling intravaginally. While no body fluids were grossly visible, microscopic contamination was still possible. Since perforations were noted in close, and even consecutive scans, this study underscores the need for routine probe disinfection between examinations. 相似文献
