BACKGROUND: A recent hypothesis suggested that in many cases cysticercal granulomas represent recently established Taenia solium metacestodes rapidly destroyed by the host's immune system. Here, we attempted to determine whether patients with cysticercal granulomas are younger than those with other forms of parenchymal brain cysticercosis. METHODS: Series of 185 patients with single parenchymal brain cysticercus, classified according to the stage of the parasite at the moment of diagnosis in cysts without inflammation, cysts with inflammation, granular lesions, and calcifications...

The interaction between the antimicrobial peptide gramicidin (Gr) and dipalmitoylphosphatidylcholine (DPPC)/dioctadecyldimethylammonium bromide (DODAB) 1:1 large unilamellar vesicles (LVs) or bilayer fragments (BFs) was evaluated by means of several techniques. The major methods were: 1) Gr intrinsic fluorescence and circular dichroism (CD) spectroscopy; 2) dynamic light scattering for sizing and zeta-potential analysis; 3) determination of the bilayer phase transition from extrinsic fluorescence of bilayer probes; 4) pictures of the dispersions for evaluation of coloidal stability over a range of time and NaCl concentration...

A cell line designated HOTHC was established from an anaplastic carcinoma (giant cell type) of the thyroid gland of 80-year-old woman. The HOTHC line grew rapidly in multilayer without contact inhibition, and more than 120 serial passages were made within 27 months. The cells were spindle or polygonal in shape and revealed neoplastic and pleomorphic features. These cells were characterized as containing coloid droplets and poorly developed rough-endoplasmic reticulum in the cytoplasm. Doubling time was about 24 hours and plating efficiency was about 70%...

BACKGROUND: Hyaluronic acid (HA), a high-molecular weight glycosaminoglycan, has been considered to be involved in the growth and progression of malignant tumors in several experimental studies. The objective of this work was to evaluate the cytosolic HA content in breast cancer, its possible relationship with clinicopathological tumor parameters and steroid receptor status, as well as its potential prognostic significance. METHODS: Cytosolic HA levels were examined by means of immunoradiometric techniques in 850 patients with invasive breast cancer...

INTRODUCTION: Renal oncocytoma is a benign tumor that in some series represents up to 18% of all solid neoplasms measuring 4 cm or less. Since radiologic distinction between a renal cell carcinoma and oncocitoma is practically impossible, the histologic examination represents the cornerstone of diagnosis. Follow up will be greatly modified by the diagnosis of oncocytoma since it displays a benign course. Eight cases are presented here that were treated at our institution with special mention to diagnosis and therapy...

HAES 130/04 Voluven is a new coloid plasma expander with better farmacokinetic properties as other well-known HAES solutions. It's reflected with quick volume 1 effect, plato takes about 4 and its clinical effect lasts for 6 hours. Voluven is metabolised by alfa-amilase and eliminated through kidney in 24 hours. Anafilactoid reactions are very rare, pruritus appears only with extensive long- term use. Voluven interferes with haemostasis less than other HAES solutions. With its use needs for homologic blood transfusion are diminished...

Having left Lódź in 1906 Władysław Kopaczewski (1886-1953) studied physics, chemistry and biology at Swiss universities. In 1911 he moved to France where he conducted research in coloidal chemistry simultaneously obtaining a physician's diploma and an MD. During 42 years he spent in France he was dealing with biological systems physics, doing research in medicine, nutritive chemistry and cosmetology. He created an original conception of cancer disease. His theory allowed him to provide the theoretical bases of the cancer physics and to suggest a diagnositic method to direct the search for means of the cancer therapy...

A case of 75-year-old man with extremely rare primary liposarcoma of the bone was presented. Stains for lipid, Sudan III, Sudan IV, and Oil Red "O", demonstrated the presence of intracellular lipid in the lipoblasts. Similarly, the S-100 immunoreactivity and electron microscopic findings of tumor cells confirmed the diagnosis of liposarcoma. Histochemical stains for PAS, Alcian-blue, mucikarmin, Toluidin-blue and Coloidal Iron were negative.

This is a report of two cases of congenital goiter in which it was possible to indicate, through immunohistochemistry method, the disorder in the hormonal synthesis. One of these cases was of a sixteen-year-old woman, with goiter since childhood who used thyroid hormone replacement for ten years. Pathology showed coloid goiter with follicular adenoma. Immunohistochemistry showed strong mainly apical follicular cell thyroglobulin. Thyroglobulin was not found in the coloid. This finding is compatible with a malfunction of thyroglobulin exocitosis...

The ultrastructure of R. solani AG-9 (S-21, ATCC 62804) was investigated with transmission electron microscopy (TEM). The most important characteristics were those related with cell wall thickness, cytoplasmic matrix composition, number of nuclei and nucleoli and secretory material production. The majority of examined hyphae showed lateral cell walls thinner than those recorded before. The cytoplasmic matrix consistently appeared differentiated into two classes, one formed by a highly electron dense granular fine material and the other one showing a coloidal substance of very low density which give these cells a 'tiger-like' aspect...

Shock is one of the most difficult problems an obstetrician can face. Hemorrhage is the main reason of shock. A descriptive and retrospective research was conducted at Instituto Nacional de Perinatología, from January 1992 to May 1996, including all patients admitted to the intensive care unit with diagnosis of shock. There were found 90 cases with diagnosis of shock, 82 were hipovolemic, and 8 cases had the septic kind of shock. The average of age was 32.2 years, with a gestational age between 6.2 to 41.4 weeks ...

The synaptonemal complexes (SCs) are nuclear structures specific for meiosis. They have a central role in homolog chromosomes coupling; they are essential in crossing over events and chromosomic segregation during the first meiotic division. When its joining ends in pakiteno stage, each synaptonemal extends along the bivalent joining the ends to nuclear wrapping. The SCs are characterized by the presence of two lateral elements and a central region. The lateral elements are parallel and equidistant. The chromatine of homolog chromosomes fixes in a series of loops to these elements...

Brucella native haptens (NHs) extracted with hot water from smooth (S)-type B. abortus and B. melitensis were purified to high levels of serological activity and compared with the polysaccharide obtained by acid hydrolysis (PS) of the S lipopolysaccharide (S-LPS). By 13C nuclear magnetic resonance analysis, NHs showed the spectrum of a homopolymer of alpha-1,2- or alpha-1,2- plus alpha-1,3-linked 4-formamido-4,6-dideoxy-D-mannose (N-formylperosamine) previously reported for the LPS O chain. However, while PS contained up to 0...

The aim of the research is to establish and confirm the diagnoses of patients with suspected haemangioma of the liver with completed ultrasonography. A group of 92 patients were checked by scintigraphy after the equilibration of marked eritrocytes in the circulation. After the marking dose of 99mTc-Sn-PYP in a dose of 555 MBq scintigraphy and static scintigram of the liver (early and late, after 3 hours) were done. During the clinical studies the classic scintigraphy of the liver by 99mTc-S-coloid was done in all the patients...

I. Moldovan (1923) demonstrated in the blood ultrafiltrate from anaphylactically prepared guinea pigs, which believed to anaphylactic shock, or which were previously injected with coloidal substances as India ink to stimulate the RES, an antianaphylactic principle named Reticulin-M(R). Authors extracted R from organs rich in RES with acetone, established their, peptidic nature and tested it on anaphylactic prepared guinea pig uterine horns in vitro. The peptides were fractioned by high voltage paper electrophoresis...

A fast and readily applicable method is suggested for the determination of the biochemical reactions of the spore producing anaerobic organisms. A pepton coloid medium with the addition of 0.15 per cent agar-agar was used as a basic nutrient medium. The cultivation of bacteria did not require any special conditions. Reading of the results was carried out with the addition of 0.1 per cent phenol red after 48 hours of incubation of the cultures. This method showed a number of advantages over the methods used so far...

Liver subtraction scans using 99Tcm sulphur coloid and 75Se-selenomethionine were carried out in 58 patients with suspected hepatoma. Of the 18 patients with hepatoma proven by histology, 16 showed selective concentration of selenomethionine in the tumour, giving a true positive rate of 89%. Of the 40 patients who did not have hepatoma, 32 scans showed no evidence of selective concentration of selenomethionine, giving a true negative rate of 80%. The false positive rate was 8% in non-cirrhotic patients with focal disease, but 55% in patients with cirrhosis...
