Abstract
We present six cases of superior vena cava syndrome caused by a malignant tumor that were treated by percutaneous endoprostheses. The technique is described and the results evaluated. In one case there was acute thrombosis of the endoprosthesis that was treated by urokinase. No other complications were observed. A patient died one month later due to progression of the tumor. The remaining cases were asymptomatic for longer than 6 months. It was concluded that endoprostheses for superior vena cava syndrome are efficient, with quick improvement of the symptomatology.

Abstract
Based on the existence of choline acetyltransferase and acetylcholine in human placenta, we have investigated the presence of muscarinic acetylcholine receptors in brush-border and basal plasma membranes from human term placenta. Radioligand binding assay, using [3H]N-methyl-scopolamine as tracer, showed the existence of acetylcholine muscarinic receptors in brush-border (Kd 0.28 +/- 0.04 nM; Bmax 9.4 +/- 1.6 fmol/mg protein) and basal plasma membranes (Kd 0.24 +/- 0.05 nM; Bmax 34.3 +/- 6.3 fmol/mg protein). In order to perform a pharmacological characterization of these receptors, competition binding experiments were carried out using the muscarinic receptor antagonists pirenzepine, (11(2-diethyl-amino)methyl)-1-piperidinylacetyl-5-11-dihydro-6H-py rido(14) benzodiazepine (AF-DX 116), himbacine, 4-diphenylacetoxy-N-methylpiperidine methiodide (4-DAMP), dicyclomine and hexahydro-sila-difenidol (HHSD). The results obtained showed that the muscarinic receptors in brush-border and basal plasma membranes belong to different subtypes. In brush-border membranes, the receptor found match in terms of affinity for the antagonists with the muscarinic M1 receptor subtype (Ki pirenzepine, 13.6 +/- 8.2 nM; Ki AF-DX 116, 1680 +/- 271 nM; Ki himbacine, 212 +/- 6.5 nM; Ki 4-DAMP. 1.5 +/- 0.4 nM; Ki dicyclomine, 5.1 +/- 0.8 nM; Ki HHSD, 34.3 +/- 7.3 nM), whereas the receptor in basal plasma membrane seems to be of the muscarinic M2 receptor subtype (Ki pirenzepine, 202 +/- 48 nM; Ki AF-DX 116, 124 +/- 60 nM; Ki himbacine, 20.6 +/- 4.8 nM; Ki 4-DAMP, 4.5 +/- 1.2 nM; Ki dicyclomine, 54.6 +/- 22 nM; Ki HHSD, 89.2 +/- 15.8 nM). The results obtained show the existence of muscarinic acetylcholine receptors in brush-border and basal plasma membranes from human term placenta with a different distribution pattern in terms of number of receptors and distribution of different subtypes. The functional significance of these findings is as yet unknown, but these receptors probably mediate different functions as they belong to different subtypes and are coupled to different second messengers.

Abstract
The King penguin (Aptenodytes patagonicus) has been studied on Possession Island, Crozet Archipelago (46 degrees 25'S-51 degrees 45'E). It is an offshore feeder, but it breeds on land. Its breeding cycle is unusually long (about 14 months). It starts at the beginning of spring, is interrupted during 5 months of winter, and ends in the next spring. Furthermore, it is characterized by a long parental care period, of about 11 months, including the winter interruption. In fact, care given to the egg and the chick is biparental, which supposes that parental behavior includes both parents. Each parent alternates care given to the egg and to the chick on land and foraging bouts at sea. An incubation bout, or a chick care bout, is called a shift. Prolactin is the hypophyseal hormone known to be correlated with incubation and chick care. We studied the mechanism of the maintenance of prolactin during the parental care period in the King penguin, a period which is unusually long. In many species, prolactin secretion has been shown to be stimulated by the presence of eggs and/or chicks, but in the King penguin, prolactin secretion is observed throughout the entire period of parental care, despite the fact that the birds leave the egg and the chick repeatedly and for extended periods of time to feed. Prolactin levels rise significantly at the beginning of courtship; females have significantly higher prolactin levels than males during courtship, copulation, and the period of waiting for egg laying. In both sexes, prolactin levels remain high during incubation and the first part of chick rearing, before winter. Prolactin concentrations decline somewhat during the winter period of minimal parental care, but remain that level in spring when parental care starts again. The level returns to basal value during molt. Prolactin levels rise during the incubation shifts but not over the course of contact with young. Prolactin values remain high in unsuccessful breeders, possibly preventing the birds from relaying, but remain low in immature birds. These data raise questions about how prolactin secretion is controlled in this species. The hypothesis of a programmed secretion of prolactin is advanced.

Abstract
Changes in plasma LH, prolactin, testosterone, estradiol, and progesterone were investigated throughout moult and reproduction in free-living male and female Gentoo penguins (Pygoscelis papua) at Crozet Island (46 degrees S, 51 degrees E), where this species is able to relay after a reproductive failure. In both sexes, LH, prolactin, and steroid hormones, remained at basal levels during the moult. LH level was highest at the time of arrival at the colony for breeding and, although it decreased after courtship, it did not drop at basal value by incubation and first chick brooding period. Prolactin peaked for both chick brooding periods; replacement clutch was associated with an increased secretion of LH, whereas high prolactin levels were maintained. Testosterone, in male, and estradiol, in female, peaked during courtship I and chick brooding II; progesterone, in female, peaked during courtship I and II. These hormonal patterns are consistent with those observed in passerine species which are also able to relay after a reproductive failure. Winter breeding observed at Crozet Island might reflect the extreme adaptive capacity of Gentoo penguin species.

Abstract
Two monoclonal antibodies that react with Salmonella enteritidis in chicken tissue, eggs, and environmental samples were used to develop a rapid enzyme-linked immunosorbent assay (ELISA) screen and agglutination assay for the specific detection of S. enteritidis. S. enteritidis was detected in 100% of egg samples and 99.8% of various field and research samples by both ELISA and traditional microbiological isolation and identification techniques. Results of titer experiments indicate that as few as 10(4) organisms can be detected by ELISA.

Abstract
The glutaraldehyde test (GT) is performed by mixing whole blood with a 1.25% glutaraldehyde solution. Gelification time is shorter in tuberculous cattle. This test was performed in blood samples obtained from: (a) 48 cattle with bacteriologically confirmed tuberculous lesions; (b) 61 animals with no evidence of tuberculosis at the time of slaughterhouse inspection, 14 of which had hydatid cysts; (c) 260 tuberculin-negative apparently healthy animals, and (d) 21 cattle, also tuberculin-negative but serologically positive for brucellosis. Sensitivity for detecting tuberculosis was 85.4% (41 of 48 animals). The test was negative in 298 out of 307 healthy animals (97.1% specificity). This specificity decreased when the test was applied in animals with evidence of diseases other than tuberculosis. This simple, rapid and inexpensive method could play a complementary role to the tuberculin test for detecting tuberculous cattle, especially in endemic areas with scarce resources and facilities.

Abstract
In the 59 hypertensive patients submitted to percutaneous transluminal angioplasty (PTA) of the renal artery, there was an immediate success in the blood pressure in 91.5% and a later one of 79.6%. In these patients we obtained better results: 81.4% in the unilateral lesions, more than in the bilateral ones--72.7%; 82.5% in the renal artery trunk lesions, more than in the ostium ones--71.4%; 88.9% in the lesions of fibromuscular origin, more than in the aterosclerotic ones--75%; 84.4% in up to 55 years old patients, more than in older ones--71.4%. These differences were not significant. The results of renal angioplasty in renovascular hypertension suggest this type of intervention as an alternative treatment.

Abstract
Renal replacement therapy (RRT) for Brazilian children with uraemia has been utilized since 1970 in the state of Rio Grande do Sul. One hundred and eighty patients receiving this therapy between 1970 and 1988 have been reviewed. The annual acceptance rate of new paediatric patients in this period increased from 0.6 to 6.5 patients per million child population. Glomerulonephritis (36.1%) and pyelonephritis including urological anomalies (31.7%) were the most frequent causes of end-stage renal disease. Outpatient hospital haemodialysis was the primary form of dialytic treatment in patients 5-15 years of age. Continuous ambulatory peritoneal dialysis was more often used in patients less than 5 years of age. The survival after 1 year on dialysis was 79.9% for children aged 5-15 years starting dialysis during the period 1985-1988. Fluid overload with congestive heart failure and infection were the main causes of death in children on dialysis. Eighty-four children received 93 grafts; only 14 (15%) were from cadaveric donors. One-year patient and graft survival of first living-related donor transplants were 92.2% and 78.5% respectively during the period 1985-1988. Infection accounted for 43.5% of deaths after transplantation. We conclude that RRT is becoming increasingly successful for children in our region but that greater emphasis upon patient compliance with all forms of RRT and upon cadaver kidney donation is needed.
