Ghrelin plasma levels, gastric ghrelin cell density and bone mineral density in women with rheumatoid arthritis
Provedor de dados: 56
Autores: Maksud,F.A.N.; Kakehasi,A.M.; Guimarães,M.F.B.R.; Machado,C.J.; Barbosa,A.J.A.
Generalized bone loss can be considered an extra-articular manifestation of rheumatoid arthritis (RA) that may lead to the occurrence of fractures, resulting in decreased quality of life and increased healthcare costs. The peptide ghrelin has demonstrated to positively affect osteoblasts in vitro and has anti-inflammatory actions, but the studies that correlate ghrelin plasma levels and RA have contradictory results. We aimed to evaluate the correlation between total ghrelin plasma levels, density of ghrelin-immunoreactive cells in the gastric mucosa, and bone mineral density (BMD) in twenty adult women with established RA with 6 months or more of symptoms (mean age of 52.70±11.40 years). Patients with RA presented higher ghrelin-immunoreactive cells...

Argyrophil cell density in the oxyntic mucosa is higher in female than in male morbidly obese patients
Provedor de dados: 56
Autores: Maksud,F.A.N.; Kakehasi,A.M.; Barbosa,A.J.A.
Obesity is a multifactorial disorder often associated with many important diseases such as diabetes, hypertension and other metabolic syndrome conditions. Argyrophil cells represent almost the total population of endocrine cells of the human gastric mucosa and some reports have described changes of specific types of these cells in patients with obesity and metabolic syndrome. The present study was designed to evaluate the global population of argyrophil cells of the gastric mucosa of morbidly obese and dyspeptic non-obese patients. Gastric biopsies of antropyloric and oxyntic mucosa were obtained from 50 morbidly obese patients (BMI &gt;40) and 50 non-obese patients (17 dyspeptic overweight and 33 lean individuals) and processed for histology and Grimelius...

Influence of acute renal failure on the mononuclear phagocytic system
Provedor de dados: 56
Autores: Sousa,V.R.A.; Sousa,A.A.; Petroianu,A.; Simal,C.J.R.; Barbosa,A.J.A.
Several studies show the ability of macrophages to remove particles injected into the bloodstream. This function seems to be increased in the presence of acute renal failure. The objective of the present study was to assess the phagocytic function of the main organs (spleen, liver and lung) of the mononuclear phagocytic system in renal and postrenal failures. Fifteen rats (250-350 g) were divided into three groups (N = 5): group I - control; group II - ligature of both ureters, and group III - bilateral nephrectomy. On the third postoperative day, all animals received an iv injection of 1 ml/kg 99mTc sulfur colloid. Blood samples were collected for the assessment of plasma urea, creatinine, sodium, and potassium concentrations and arterial gasometry....

Effect of sodium carboxymethylcellulose and methylprednisolone on the healing of jejunal anastomoses in rats
Provedor de dados: 56
Autores: Sousa,A.A.; Petroianu,A.; Trapiello Neto,V.; Rios,V.S.; Barbosa,A.J.A.
Sodium carboxymethylcellulose (SCMC) has been effective in reducing adhesion formation and corticosteroids reduce the inflammatory process. The objective of this study was to define the intraperitoneal (ip) effects of SCMC combined with intramuscular (im) methylprednisolone on peritoneal adhesion formation and on jejunal anastomosis healing in rats. Twenty Wistar rats (200-350 g) were divided into four groups (N = 5): groups I and III (controls) 5 and 21 days of treatment before sacrifice, respectively; groups II and IV (experimental groups) 5 and 21 days of treatment, respectively. SCMC (1%) was infused into the abdominal cavity and methylprednisolone (10 mg kg-1 day-1) was injected im daily from the day before surgery for animals of groups II and IV. All...
