BACKGROUND/AIMS: To introduce and review the results of the different treatment modalities of infected pancreatic necrosis and abscess that have been used during a 1-year period. As well, to assess the technique and indications of retroperitoneal drainage that is selectively performed for the management of peripancreatic necrosis because of the problem of intraperitoneal drainage. METHODS: Five patients with infected pancreatic necrosis or abscess were operated on from July 1997 to June 1998. Two undrewent surgical necrosectomy and retroperitoneal drainage and 3 had a classical procedure of multiple intraperitoneal drainage after necrosectomy. RESULTS: Two of 5 patients that had retroperitoneal drainage performed were successful of wide ranging necrosectomy of retroperitoneal necrosis or abscess through one drainage site and the left flank, resulting in a decreased rate of intraperitoneal contamination, discomfort and disability. CONCLUSION: The advantages of retroperitoneal drainage for wide ranging retroperitoneal pancreatic necrosis are made possible by draining the retroperitoneal route from the retroperitoneal cavity to the same retroperitoneal external opening. The use of retroperitoneal drainage seemed to be a significant factor for improvement by providing a reliable drainage of retropancreatic areas and by avoiding the opening of the peritoneal cavity

This study was conducted to elucidate the biological role of the overproduced nitric oxide (NO), interleukin-l (IL-l), and interleukin-6 (IL-6) which are known to elicit inflammation, rheumatic arthritis, fever, septic shock or other fatal reactions. I investigated whether the Scarcoma 180 cells elicit NO, IL-l and IL-6 production in vivo and in vitro by measuring the NO, IL-1 and IL-6 level in the splenocyte adherent cell (AD), non-adherent cell (NAD) and whole cell (W) exposed to sarcoma 180 cells. I also measured the NO, IL-1 and IL-6 level in the plasma and peritoneal fluid of the sarcoma 180 cell-transplanted mice after 2 hours, 4 hours, 6 hours and 24 hours of incubation. 1. In the splenocyte exposed to sarcoma 180 cells, the NO production of AD and NAD increased after 2, 4, and 6 hours but decreased after 24 hours of incubation. In the whole cell, the NO production was variable; it showed increased level of synthesis at 2 hours, decreased level at 4 hours, increased level again at 6 hours, and decreased level at 24 hours of incubation. In the plasma of the sarcoma 180 cell-transplanted mice, the NO synthesis significantly increased from the 6 hours of incubation. In the peritoneal fluid, the NO production significantly increased until the 4 hours of incubation then decreased gradually. However, it showed higher level of NO production compared to the control group. 2. For the splenocyte AD cell exposed to saracoma 180 cells, the IL-1 level decreased after 6 hours of incubation. For the W cells, the IL-1 level decreased at 4 hours then increased until 24 hours of incubation. The NAD cell showed increased level of IL-I production from 2 to 24 hours. All these cells showed significantly increased level of IL-1 production compared to the control. In the plasma of the sarcoma 180 cell-transplanted mice, the IL-1 production increased more than twice the level of control from the beginning. In the peritoneal fluid, no IL-1 production was detected as in the control. 3. The IL-6 synthesis of the sarcoma 180 cell-exposed splenocyte singnificantly increased compared to the control: the AD cell showed increased level of IL-6 production after 4 hours of incubation. For the NAD cell, increased level of IL-6 was detected at 2 hours after the incubation. In the plasma of the sarcoma 180 cells transplanted mice, the IL-6 level at 2 hours after incubation was 64.22+/- 5.85 pg/ml. After 4 hours of incubation, the level decreased to 43.55+/-1.56 pg/ml. At six and 24 hours after the incubation, no IL-6 was detected. In the control, IL-6 production was not detected. In the peritoneal fluid, the IL-6 production level was 712.41+/-4.27 pg/ml after 2 hours and 225.71+/-9.74 pg/ml after 4 hours of incubation, producing singnificantly higher level of IL-6 compared to the control. After 6 hours of incubation, IL-6 level was 8.27+/-0.78 pg/ml. After 24 hours of incubation, it decreased to 1.38+/-0.39 pg/ml as time proceeds. After 24 hours of incubation, the IL-6 level was the same as the control. These results suggest that the mice which were exposed to sarcoma 180 cells, nitric oxide, interleukin-1 and interleukin-6 which may lead to inflammation, fever, sepsis and septic shock. This study also helps us better understanding of the role of cytokines in inflammatory reaction.

PURPOSE: To determine whether seminal malondialdehyde and carbonyl group have any relation to sperm motility. MATERIALS AND METHODS: Human semen samples were obtained by masturbation after 3 days of abstinence from patients consulting an infertility clinic. Using conventional semen analysis, samples were divided into two groups according to sperm motility (group 1: motility > OR =50%, group 2: motility <50%). Malondialdehyde and carbonyl group were measured in whole semen. RESULTS: The amount of malondialdehyde and carbonyl group was slightly lower in group 1 than group 2. CONCLUSIONS: Although the difference between the groups was not statistically significant, it seems possible that malondialdehyde and carbonyl group, which are produced from reactive oxygen, are negatively correlated with sperm motility.
