OBJECTIVES The ovarian tumor microenvironment, ie, the peritoneal fluid, is an intriguing research subject. The goal of this study was to assess the behavior of selected cytokines and growth factors within the peritoneal fluid in pathologies associated with ascites and to assess the relationship between the levels of these substances and select prognostic factors of ovarian cancer. METHODS A ...
In patients on long-term continuous ambulatory peritoneal dialysis, the efficiency of dialysis declines because of peritoneal neovascularization and loss of peritoneal mesothelial cells. In this study, we investigated the influence of lactate and bicarbonate in peritoneal dialysis fluid on such changes of the peritoneum. We studied the production of vascular endothelial growth factor (VEGF) and...

Fibrous adhesions remain a major sequela of abdominal surgery. The proinflammatory peptide substance P (SP), known to participate in inflammatory events, may play a key role in adhesion formation. This hypothesis was tested by using an antagonist, CJ-12,255 (Pfizer), that blocks the binding of SP to the neurokinin 1 receptor (NK-1R). Adhesion formation was surgically induced in the peritoneum o...
Considering the great advances regarding the diagnosis and treatment of peritonitis and with respect to the prevalence of patients with primary peritonitis referred to hospitals affiliated to Shiraz university of Medical sciences, this study was performed to evaluate the predisposing and prognostic factors of this condition in children during the years 1982-1992 The descriptive protocol of thi...
The i.p. inoculation of C3H mice with 5 times 10-6 cells of a transplantable ovarian carcinoma invariably evokes accumulation of large amounts of ascitic fluid. Histological and pharmacotherapeutic studies indicate that obstruction to peritoneal lymphatic drainage is a key factor in the formation of carcinomatous ascites in this model. In the early stages of ascites formation, an intense inflam...
Peritoneal dialysis is a technique whereby infusion of dialysis solution into the peritoneal cavity is followed by a variable dwell time and subsequent drainage. Continuous ambulatory peritoneal dialysis (CAPD) is a continuous treatment consisting of four to five 2-L dialysis exchanges per day (Fig. 4-1A). Diurnal exchanges last 4 to 6 hours, and the nocturnal exchange remains in the peritoneal...
Studies of the adequacy of peritoneal dialysis and recommendations have assumed that renal and peritoneal clearances are comparable and therefore additive. The CANUSA data were reanalyzed in an effort to address this assumption. Among the 680 patients in the original CANUSA study, 601 had all of the variables of interest for this report. Adequacy of dialysis was estimated from GFR (mean of rena...
Transforming growth factor-β (TGF-β) is believed to play a major role in the aetiology of peritoneal endometriosis. We aimed to determine if the peritoneum is a source of TGF-β and if peritoneal TGF-β expression, reception or target genes are altered in women with endometriosis. Peritoneal fluid, peritoneal bushings and peritoneal biopsies were collected from women with and without endometriosi...
Haemophilus influenzae is a rarely reported cause of peritonitis in chronic ambulatory peritoneal dialysis (CAPD) patients. In this report, a peritonitis case due to H. influenzae in a 32-years-old female patient with end-stage renal failure receiving CAPD for 7 years, has been reported. The patient was admitted to our clinic with the complaints of nausea, vomiting, abdominal pain, and cloudy d...
