Abstract
UNLABELLED The immunomodulator effect of Bioflora probiotic on T (CD4+) and B (CD20) lymphocytes in gastrointestinal mucosa and intestinal bacterial translocation was studied using Wistar rats (n = 10 per group). Two experiments were used: (I) stress with immobilization and water immersion at 22 degrees C for 7 h plus the application of indomethacin (Indo) 10 mg/kg SC every 24 h for 3 days (comparator group), and (II) stress experiment I with the addition of 1 mL of Bioflora applied through a orogastric tube every 12 h for 3 days. At the 4th day, in asepsis, a dissection laparotomy of liver, spleen, mesenteric lymphatic nodes, and cecum was performed for microbiological culture, and stomach, ileum, and colon were also dissected for immunohistochemical and quantification of CD4+ and CD20. Findings in experiment I revealed cecum bacterial overdevelopment of 6 x 10(10) +/- 2.3 x 10(9) colony-forming units (CFU) (P < 0.01) and positive cultures in liver, spleen, and all mesenteric lymphatic nodes. On the other hand, in the group treated with Probiotic Bioflora, cecum without overdevelopment (3 x 10(6) +/- 1.3 x 10(5) CFU), negative cultures in liver and spleen, and in lymphatic nodes two positive and eight negative cultures for E. coli and P. vulgaris (P < 0.01) were observed. Immunohistochemistry revealed a relevant increase of T lymphocytes (CD4+) in ileum and colon. CONCLUSIONS Bioflora probiotic was shown to be an intestinal immunomodulator that induced increased T (CD4+) lymphocytes that also offer prophylaxis of intestinal bacterial translocation in a stressed rat model.

Abstract
Summary: Current existing or proposed standards and guidelines in the field of psychological assessment are confined to psychological tests and psychological testing. But tests constitute only one category of psychological assessment procedures, and testing is only one of many available strategies or classes of actions in the course of the assessment process. Tests and testing are closely linked to a certain approach to psychological assessment, i. e., the psychometric one. This is one reason why it is relatively easy to formulate and establish standards or guidelines in the case of psychological tests and testing. The much more comprehensive assessment process is an indispensable part of any approach to psychological assessment, even of those that do not use psychometric tests. This makes the formulation of guidelines for the assessment process an ambitious and very difficult enterprise. But it can be done, at least at the level of recommendations that could help the assessor to cope with the complexities and demands of assessment processes in various contexts of psychological assessment. The European Association of Psychological Assessment (EAPA) decided to sponsor the development of Guidelines for the Assessment Process (GAP), setting up a Task Force for this specific purpose. The GAP introduced in this paper are intended as a first proposal to initiate a broad discussion about how to improve the practice of psychological assessment and the education and training of psychological assessors.

Abstract
BACKGROUND Helicobacter pyloriinfection of the gastric mucosa in humans is usually acquired early in life. The chronic inflammation that ensues involves the increased production of inflammatory cytokines. Published data on production of these mediators by gastric mucosa of H. pylori-infected children are few. METHODS Seventy-nine children, aged 5 to 18 years, referred for upper gastrointestinal endoscopy to four separate hospitals in Chile, were studied. The concentrations of interleukin (IL)-1beta, IL-6, IL-8, and tumor necrosis factor alpha were measured in homogenates of gastric mucosal biopsy specimens. Cytokine expression was confirmed by reverse transcription polymerase chain reaction. These data were correlated with the patients' clinical, histologic and sociodemographic status. RESULTS Patient rate of colonization by H. pylori was inversely correlated with socioeconomic status (P < 0.005) and positively correlated with age (P < 0.0025). In gastric mucosa, concentrations of IL-1beta, IL-8, and tumor necrosis factor alpha were all significantly higher in H. pylori-positive patients than in H. pylori-negative patients and in patients who had histologic gastritis than in those with normal gastric mucosa. In patients with peptic ulcer disease, only IL-1beta and IL-8 concentrations were significantly elevated when compared with those of patients without ulcers. Interleukin-6 concentrations were comparable among the different groups analyzed. CONCLUSIONS This study suggests that increased gastric mucosal production of the proinflammatory cytokines IL-1beta and IL-8 is probably involved in H. pylori-associated gastric damage in children and may be crucial in determining the different clinical outcomes.

Abstract
Glucose transporters play an essential role in the acquisition of glucose by the brain. Elevated expression of glucose transporter-1 has been detected in endothelial cells of the blood-brain barrier and in choroid plexus cells of the blood-cerebrospinal fluid barrier. On the other hand, there is a paucity of information on the expression of glucose transporters in the ependymal cells that line the walls of the cerebral ventricles. The tanycytes are specialized ependymal cells localized in circumventricular organs such as the median eminence that can be segregated into at least three types, alpha, beta1 and beta2. The beta2 tanycytes form tight junctions and participate in the formation of the cerebrospinal fluid-median eminence barrier. Using immunocytochemistry and in situ hybridization, we analyzed the expression of hexose transporters in rat and mouse hypothalamic tanycytes. In both species, immunocytochemical analysis revealed elevated expression of glucose transporter-1 in alpha and beta1 tanycytes. Intense anti-glucose transporter-1 staining was observed in cell processes located throughout the arcuate nucleus, in the end-feet reaching the lateral sulcus of the infundibular region, and in cell processes contacting the hypothalamic capillaries. On the other hand, there was very low expression of glucose transporter-1 in beta2 tanycytes involved in barrier function. In contrast with the results of the cytochemical analysis, in situ hybridization revealed that tanycytes alpha, beta1, and beta2 express similar levels of glucose transporter-1 mRNA. Further analysis using anti-glial fibrillary acidic protein antibodies to identify areas rich in astrocytes revealed that astrocytes were absent from areas containing alpha and beta1 tanycytes, but were abundant in regions containing the barrier-forming beta2 tanycytes. Overall, our data reveal a lack of correlation between participation in barrier function and expression of glucose transporter-1 in hypothalamic tanycytes. Given the virtual absence of astrocytes in areas rich in alpha and beta1 tanycytes, we speculate whether the tanycytes might have astrocyte-like functions and participate in the metabolic coupling between glia and neurons in the hypothalamic area.

Abstract
Five experimental models were developed in different groups of Wistar rats (N = 15) to study selective COX-2-inhibitor NSAIDs such as celecoxib and rofecoxib, as follows: (1) dose-dependent oral Celecoxib and Rofecoxib for 5 days, and 24 hr after oral indomethacin; (2) Same as 1 but subcutaneously; (3) gastric ulcer induced by glacial acetic acid; (4) duodenal ulcer induced by cysteamine; and (5) stress by immobilization and immersion in water at 15 degrees C for 6 hr. Celecoxib and Rofecoxib, either orally or subcutaneously, did not produce necrotic lesions in healthy gastrointestinal mucosa (0%), showing normal histology. In contrast, previously indomethacin-induced lesions were aggravated (90%, P < 0.001). Total necrosis in the small intestine as well as increased ulcers and perforation of gastric and duodenal ulcers induced by acetic acid and cysteamine were observed. There was also aggravation of the necrotic gastric area in stress (60-90%, P < 0.05). Celecoxib and rofecoxib showed neutrophilia (5000/mm3) similar to that with indomethacin. In contrast, there was no leukocyte infiltration in the gastric múcosa; thus, we can consider it a selective COX-2 NSAID. In conclusion, celecoxib and rofecoxib at doses causing COX-2 but not COX-1 inhibition did not produce toxic lesions in healthy gastrointestinal mucosa, yielding a broad therapeutic margin. In contrast, when administered in altered gastrointestinal mucosa, they aggravated and complicated gastric ulcers as well as necrosis in the small intestine, consequently restricting their clinical use.

Abstract
UNLABELLED Five experimental models were carried out in different groups of Wistar rats (n = 15) in order to study selective (cyclo-oxygenase) COX-2 non-steroid antiinflammatory inhibitors, such as celecoxib and rofecoxib, as follows: 1) Dose-dependent oral celecoxib and rofecoxib for 5 days, and 24 hours after oral indomethacin. 2) Same as 1, but subcutaneously. 3) Gastric ulcer induced by means of glacial acetic acid. 4) Duodenal ulcer induced by means of cysteamine. 5) Stress due to being kept under restraint and immersion in water at 15 degrees C for 6 hours. Celecoxib and rofecoxib, either orally or subcutaneously, did not produce necrotic injuries in healthy gastrointestinal mucosa (0%), showing normal histology. On the other hand, the injuries previously induced by indomethacin worsened (90%, p < 0.001). Total necrosis of small intestine as well as increased ulcer and perforation of gastric and duodenal ulcers induced by acetic acid and cysteamine were observed. There was also worsening of gastric necrotic area with stress (60-90%, p < 0.05). Celecoxib and rofecoxib showed neutrophilia (5,000/mm3) similar to that presented by indomethacin, but there was no leukocyte infiltration in the gastric mucosa; thus we can consider it a COX-2 selective NSAID (non-steroidal anti-inflammatory drug). CONCLUSION Dose-dependent administration of celecoxib and rofecoxib as COX-2 inhibitors and non-COX-1 inhibitors, respectively, did not produce toxic injuries on healthy gastrointestinal mucosa, thus providing a broad therapeutic spectre. On the other hand, when administered in presence of altered gastrointestinal mucosa, they worsened and complicated gastric ulcers, and also induced necrosis in the small intestine, thereby restricting their clinical use.

Abstract
Malignant hypertension is associated with high mortality and morbidity usually caused by cardiovascular events. The course and prognosis of malignant hypertension patients treated with renal replacement therapy has not been thoroughly investigated. In the present work, we compared the clinical evolution and survival of 24 end-stage renal failure malignant hypertension patients with that of a group of individually matched renal failure patients admitted to the same dialysis center during a period of 21 years. Survival rates at 1, 5 and 8 years were 87, 82 and 50% for malignant hypertension patients and 87, 75 and 65% for controls, respectively (p = 0.766, NS). Nonfatal cardiovascular complications occurred in 2 individuals of each group. The most important cause of death in both groups was cardiovascular. The frequency of fatal cardiovascular events was similar in the two groups: 64% of deaths for malignant hypertension and 71% for controls (NS). In conclusion, previous malignant hypertension did not increase the risk of patients in long-term hemodialysis in our series.

Abstract
We used immunohistochemistry with anti-glucose transporter antibodies to document the presence of facilitative hexose transporters in the fetal human brain. GLUT1 is expressed in all regions of the fetal brain from ages 10 to 21 weeks. GLUT1 was present in the endothelial cells of the brain capillaries, the epithelial cells of the choroid plexus and neurons. High expression of GLUT2 was observed in the granular layer of the cerebellum in brains 21 weeks old, but GLUT2 immunoreactivity was absent at earlier stages. GLUT3 and GLUT4 immunoreactivities were absent at all stages studied. GLUT5 immunoreactivity was evident only in the cerebellar region of 21-week old fetal brains. We conclude that GLUT1 plays a fundamental role in early human brain development. The data also suggest that the cerebellum of the developing brain has the capacity to transport fructose, a substrate that has not been previously identified as a source of metabolic energy in the adult human brain.
