Abstract
AIM The aim of this study is to describe the incidence, imaging characteristics and pathological features of pancreatic incidentalomas. Moreover, surgical indications are discussed according to the nature and location of the neoplasms. BACKGROUND Pancreatic incidental lesions are more commonly diagnosed, due to the widespread of high quality cross sectional imaging. These lesions can be cystic or solid, benign, pre-malignant or already malignant and they cover a wide spectrum of histological diagnosis. Cystic lesions are more commonly benign or at least pre-malignant. Surgery should be reserved in case of unexpected changes in aspect during follow-up or for large cysts (>3 cm). Among solid pancreatic incidentalomas, ductal adenocarcinoma is the most common diagnosis, followed by neuroendocrine tumors. Surgical treatment of pancreatic incidentaloma depends on the location of the tumor: a Whipple's procedure should be performed for neoplasms of the head, while distal pancreatectomy is indicated for body and tail lesions. Pancreatic surgery is still delicate and burdened by serious complications. Both procedures can be performed with minimally-invasive technique which is connected to lower complications rate but, at present, they have shown no advantages in terms of mortality and oncologic outcomes. CONCLUSIONS Pancreatic incidentalomas are becoming more and more common but when and how to operate them is still subject of debate. Precise criteria about treatment strategy are still lacking and definite guidelines are needed to clarify the best approach. KEY WORDS Incidentaloma, Laparoscopy, Pancreatic tumors, Surgery.

Abstract
PURPOSE This study is aimed at investigating the clinical efficacy of the 4-category classification of urgent cesarean section. METHODS Women giving birth from September 2012 to December 2014 were prospectively investigated. Urgency C-section categories were color-coded: red - maternal/fetal life threat; yellow - maternal/fetal compromise, not life-threatening; and green - early delivery necessary. Results were audited. RESULTS A total of 4,754 women gave birth in the period considered, 1,313 (27.6%) with C-section of which 867 were urgent. The code was red in 0.98% of women, and 91.5% of newborns were delivered ≤30'; yellow in 5.1%; and green in 11.7%. The mean decision-to-delivery interval (DDI) ± SD was 19.6 ± 9.5 min, 36.6 ± 15.3 (p < 0.01), and 80.3 ± 52.8 (p < 0.01), respectively; and mean umbilical pH was 7.24 ± 0.10, 7.29 ± 0.08 (p < 0.05), and 7.33 ± 0.04 (p < 0.01) in the red, yellow, and green groups, respectively. Two (4.2%) red and 4 (2.2%) yellow newborns were acidotic. Mean DDI ± SD decreased from 21.7 ± 9.7 min in the period September 2012 to February 2013 to 17.4 ± 9.7 min in the period February to December 2014 (p = NS). CONCLUSIONS Four-category classification led to achieving the target time in >90% of category 1 emergency C-sections, and stratified newborns with significantly different acidosis levels.

Abstract
In this work a novel unobtrusive technology-aided system is presented and tested for the assessment of newborns' oral-motor behavior and coordination during bottle feeding. A low-cost monitoring device was designed and developed in order to record Suction (S) and Expression (E) pressures from a typical feeding bottle. A software system was developed to automatically treat the data and analyze them. A set of measures of motor control and coordination has been implemented for the specific application to the analysis of sucking behavior. Experimental data were collected with the developed system on two groups of newborns (Healthy vs. Low Birth Weight) in a clinical setting. We identified the most sensitive S features to group differences, and analyzed their correlation with S/E coordination measures. Then, Principal Component Analysis (PCA) was used to explore the system suitability to automatically identify peculiar oral behaviors. Results suggest the suitability of the proposed system to perform an objective technology-aided assessment of the newborn's oral-motor behavior and coordination during the first days of life.

Abstract
The assessment of oral-motor behavior (OMB) represents one the earliest noninvasive ways to evaluate newborns' well-being and neuromotor behavior. This work aimed at developing a new low-cost, easy-to-use and noninvasive system for a technology-aided assessment of newborns' OMB during bottle feeding. A SUcking MOnitoring Device (SUMOD) was designed and developed to be easily integrated on a typical feeding bottle. A software system was developed to automatically treat and analyze the acquired data: proper algorithms for a fully automatic segmentation and features extraction are proposed and implemented. A set of measures of motor control and coordination are introduced and implemented for the specific application to the OMB analysis. Experimental data were collected on two groups of newborns (healthy versus low birth weight) with the SUMOD in a clinical setting.

Abstract
BACKGROUND The efficacy and safety of prosthesis fixation were studied by means of fibrin glue (Tissucol, Baxter Healthcare) during laparoscopic transabdominal preperitoneal (TAPP) treatment of inguinal and femoral hernias. METHODS Between September 2001 and December 2004, fibrin glue was used for mesh fixation during TAPP. RESULTS In this study, 320 hernias were treated for 230 patients (225 men and 5 women) with an average age of 45 years (range, 20-75 years). No perioperative complications were observed. After an average follow-up period of 26 months (range, 1-40 months), the only postoperative complications observed were six seromas (1.8%) and one trocar-site hematoma (0.3%). The mean operating time was 30 min for unilateral hernias and 50 min for bilateral hernias, whether primary or recurrent. Patients usually were discharged the day after surgery and returned to work after 5 days. CONCLUSIONS The authors' experience demonstrates that fibrin glue (Tissucol) is an effective method for mesh fixation during TAPP.

Abstract
BACKGROUND Various systems exist for prosthesis fixation in hernia repair. These techniques vary in terms of postoperative complications and pain. This study compares prosthesis fixation techniques employed in laparoscopic transabdominal preperitoneal (TAPP) hernioplasty using a visual analog scale (VAS) to quantify postoperative pain. METHODS Patients (n = 600) underwent TAPP inguinal hernia repair in a randomized prospective study. Prostheses were fixed with Protak (Tyco, Norwalk, Conn), (Group A; n = 150), EndoANCHOR (Ethicon Endo-Surgery, Inc., Cincinnati, Ohio) (Group B; n = 150), EMS (Ethicon Endo-Surgery, Inc.) (Group C; n = 150), or Tissucol (Baxter Healthcare, Milan, Italy) (Group D; n = 150). Patients were interviewed up to 1 month post-intervention. Post-operative pain was evaluated on a 0- to 10-point VAS (0 = no pain, 10 = maximum pain). Morbidity, length of stay, return to work and recurrence were also assessed. RESULTS Overall, 803 hernias were treated: 397 patients (66.2%) had unilateral hernias and 203 (33.8%) had bilateral hernias. In total, 96 (12%) hernias were recurrences and 707 (88%) were primary. Postoperative pain ranged from VAS1 to VAS2 (mild pain) between 12 hours and 72 hours with Tissucol (Group D), and it was higher in Groups A-C: Maxima ranged from VAS4 (moderate pain) with EMS to VAS7 (severe pain) with Protak at 48-hour follow-up. Significant differences in length of stay occurred, no recurrence or conversion rates were observed among groups, and morbidity was generally lower with Tissucol. Patients in Group D (Tissucol) also returned to work sooner than did Groups A-C (Protak, EndoANCHOR, and EMS). CONCLUSIONS We found differences in postoperative pain among different laparoscopic TAPP prosthesis fixation methods. The use of the biocompatible fibrin sealant Tissucol seems to reduce significantly postoperative pain, complications, and resumption to work times compared with other systems.

Abstract
INTRODUCTION Laparoscopic repair of inguinal hernias is usually achieved by totally extraperitoneal (TEP) or transabdominal preperitoneal (TAPP) techniques. The intraperitoneal onlay mesh (IPOM) could be an interesting alternative as it is much easier to perform and faster to execute. This technique is subject to correct selection of indications and to demonstration of its safety. MATERIALS AND METHODS From January 2003 to January 2006 we performed 61 laparoscopic hernia procedures on 60 selected patients (60 males with a mean age of 60 and mean weight of 76 kg) with an IPOM technique combining the Parietex composite mesh (12 cm circular model) and a fibrin glue (Tissucol) for its fixation. The glue was diluted to increase fixation time and applied to the mesh prior to positioning on the hernia defect. RESULTS Mean operative time was 10 minutes. Mean hernia diameter was 2.5 cm (+/- 0.8 cm). 10 hernias were direct, 51 were indirect and 10 out of 61 were recurrent. We did not convert any of the laparoscopic procedures. Mean hospital stay was one day; mean recovery time for working and general physical activities was five days. Patients were checked after one week, 1-3-6 months and 1-2 years. Average follow up time was 23.7 months. 1.6 % of patients showed short-term complications: one trocar site haematoma. No additional complications were reported; particularly, we had no recurrence, no seroma, no mesh migration, and no bowel obstruction or fistula. CONCLUSION Results of this study show intraperitoneal (IP) tolerance to this kind of mesh and the safety of its fixation with Tissucol. The absence of recurrence and complications could be a good reason to extend the indication of IPOM hernia repair. However, these preliminary results should be confirmed by longer follow-up.

Abstract
BACKGROUND This study aimed to evaluate the effect of fibrin glue in laparoscopic spleen-preserving procedures for traumatic rupture. METHODS From January 2002 to December 2005, six laparoscopic spleen-preserving procedures were performed for traumatic rupture using fibrin glue. Two of the cases had previous middle and lower abdominal surgery. Survey of the abdominal cavity was performed by inserting two 5- to 12-mm trocars, one 5-mm trocar, and a 30 degree scope. A complete survey of all the patients was performed. RESULTS None of the patients required laparotomy, and no postoperative bleeding occurred. The fibrin sealant achieved immediate hemostasis, and all the patients recovered without further splenic bleeding. The mean postoperative stay was 4.3 days (range, 4-5 days). All the patients were followed up for 3 to 12 months. Postoperative immunoglobulin scanning, ultrasonography, and computed tomography (CT) results were normal. CONCLUSIONS Laparoscopic management of spleen trauma can be used once a positive diagnosis has been made. It is useful for assessing the degree of splenic injury. A laparoscopic spleen-preserving procedure can be used safely for patients with stable vital data. It is an effective procedure for the evaluation and treatment of hemodynamically stable patients with splenic injuries for whom nonoperative treatment is controversial. The topical application of a fibrin sealant in splenic trauma achieves definitive hemostasis safely, rapidly, and reliably. It also is simple to use in either laparoscopic or open procedures.

Abstract
INTRODUCTION Acute colonic obstruction is a frequent emergency condition in a general surgical setting. The use of an endoscopic self-expanding stent can relieve obstruction and eventually prepare the patient for elective laparoscopic or open surgery. MATERIALS AND METHODS From September 2001 to March 2006 we treated 25 patients with acute left or transverse colonic obstruction. In 23 patients stents were positioned planning an elective procedure to be performed. In two patients with multiple liver metastases and malignant ascites only a palliation was intended (2 of 25 patients). RESULTS Mean age was 66.6 years. The 23 patients who underwent resection, 14 females and nine males, had a mean age of 65.5 years. Obstructions were located in the rectum (five), in the sigmoid (16) and in the transverse colon (two). In one patient stricture was due to radiotherapy, in twenty four cases it was due to primary cancer. Stents were successfully placed in 24 patients. In one of them two stents had to be placed due to the slippage of the first one beyond the stricture. Excellent resumption of colonic transit was achieved in all the patients. No complications were observed. In 23 patients resection was performed (19 laparoscopy; four open). Complications occurred in one patient in open group (pancreatic fistula after splenectomy) and was treated conservatively. Mean postoperative stay was 18.5 (range 9-35) days for the open group and 12 (range 9-20) for the laparoscopic group. Mean follow-up was 36 months. CONCLUSIONS Use of self expanding endoscopic colonic stents can provide excellent palliation in acute obstruction, aiming both to prepare the colon to elective surgery after adequate preparation or to palliate the stricture in case of unresectable advanced tumors.

Abstract
BACKGROUND Incisional hernia is a common complication of abdominal surgery, and it is often a source of morbidity and high costs for health care. This is a case-control study to compare laparoscopic versus anterior-open incisional hernia repair. METHODS 170 patients with incisional hernia were enrolled in this study between September 2001 and December 2004. Of these, 85 underwent anterior-open repair (open group: OG), and 85 underwent laparoscopic repair (laparoscopic group: LG). The clinical outcome was determined by a median follow-up of 24.0 months for LG and OG. RESULTS No difference was noticed between the two groups in age, American Society of Anesthesiologists (ASA) score, body mass index (BMI), and incisional hernia diameter. Mean operative time was 61.0 min for LG patients and 150.9 min for OG patients (p < .05). Mean hospitalization was 2.7 days for LG patients and 9.9 days for OG patients (p < .05). Mean return to work was 13 days (range, 6-15 days) in LG patients and 25 days (range, 16-30 days) in OG patients. Complications occurred in 16.4 % of LG patients and 29.4 % of OG patients, with a relapse rate of 2.3% in LG and 1.1% in OG patients. CONCLUSIONS Short-term results indicate that laparoscopic incisional hernia repair is associated with a shorter operative time and hospitalization, a faster return to work, and a lower incidence of wound infections and major complications compared to the anterior-open procedure. Further studies and longer follow-up are required to confirm these findings.

Abstract
PURPOSE The primary objective of this observational study was to determine the best possible dilution of fibrin glue (Tissucol) to employ for prosthesis fixing in laparoscopic treatment of abdominal wall defects and, secondly, to assess its feasibility and safety. MATERIALS AND METHODS This study was carried out in a university experimental animal laboratory in accordance with all international laws, ethics regulations and quality criteria associated with animal experiments. The tests were carried out on two pigs, using four samples of mesh (Parietex). All meshes were fixed using two different Tissucol dilutions (standard with distilled water and that with calcium chloride). Follow-up evaluations were at 15 days after 30 days, with the latter consisting of traction tests and a biopsy for histological analysis. RESULTS No post-operative complications were observed. The collagen-coated polyester meshes showed 0% adhesions, and reperitonealization had ensued after 15 days. We saw no shrinkage or migration of any of the meshes. Histopathological analyses confirmed a greater stability, greater tissue integration and the largest number of fibroblasts in meshes fixed with a 1/10 Tissucol dilution without calcium chloride. CONCLUSIONS This observational study using animals showed that the 1/10 standard dilution - not that with calcium chloride - provided the best fixation and integration and prevented the formation of intraperitoneal adhesions, provided a hydrophilic collagen film-covered mesh was used.

Abstract
INTRODUCTION The aim of this study was to establish the efficacy and tolerability of human fibrin glue (Tissucol) for the nontraumatic fixation of a composite prosthesis (Parietex) in the laparoscopic repair of small to medium-sized incisional hernias and primary defects of the abdominal wall. MATERIALS AND METHODS From October 2003 to October 2005, 40 patients underwent laparoscopic repair at the hands of one surgeon with expertise in laparoscopic surgery; all meshes were implanted in an intraperitoneal position. Follow-up visits were scheduled for 7 days and 1, 6, and 12 months. These included assessments for pain and postoperative complications. RESULTS Forty patients (24 females, 16 males) with a mean age of 50 years (range, 26-65 years) and a mean Body Mass Index (BMI) of 27 (range 25 to 30) were included in the study. Sixteen patients had incisional hernias, and 24 had primary defects. The size of the defects varied from 2 to 7 cm. Adhesiolysis was necessary in 92.5% of cases (25/40). There were no intraoperative complications or conversions. After a mean follow-up of 16 months (range, 3-24 months), no postoperative complications were observed. The mean surgical intervention time was 36 min (range, 12-40 min), with an average hospitalization time of 1 day. CONCLUSIONS The use of fibrin glue in the present study provided stable and uniform fixation of the prosthesis and minimized intraoperative and postoperative complications. Consequently, laparoscopic treatment of small to medium-sized abdominal defects using this approach is our therapeutic option of choice.

Abstract
Thrombosis of the portal system is a potentially life-threatening but otherwise underappreciated complication after splenectomy. Nonspecific and mild onset symptoms are the cause of delay in diagnosis, and the short hospital stay after laparoscopic approach could even contribute to the difficulty of early detection of this condition. The aim of this study was to verify if planned imaging controls are able to discover this complication leading to a prompt treatment. Thirty-eight patients (19 males and 19 females with a mean age of 24 years) who underwent laparoscopic splenectomy at our institution were studied to identify clinical signs of thrombosis of the portal venous system and eventually associated factors. All the patients were enrolled in a protocol of imaging surveillance using a doppler ultrasound method. Postoperative thrombosis of the spleno-portal axis occurred in 7 patients (18.9%) of the series. In 3 cases (8.1%) the thrombus extended from the splenic vein to occlude the portal axis. The complication was symptomatic in 4 cases (10.8%), whereas in 3 cases, the thrombosis was an ultrasonographic surprise in totally asymptomatic patients. Thrombosis occurred even as late as 2 months after splenectomy. Splenomegaly was the only significant factor predictive of thrombosis. Only those patients who had an early detection of portal or splenic vein thrombosis had a recanalization of the veins with anticoagulant therapy. Patients with splenomegaly who underwent laparoscopic splenectomy are at risk of thrombosis of the portal system and should undergo strict imaging surveillance and aggressive anticoagulation therapy.

Abstract
The aim of this study was to demonstrate the efficacy and safety and report the results of prosthesis fixation by means of fibrin glue during laparoscopic treatment of inguinal and femoral hernias. From September 2001 to December 2004 we employed fibrin glue (Tissucol, Baxter, Maurepas) as a means of fixation during a transabdominal preperitoneal procedure in 230 patients (225 M, 5 F) with an average age of 45 years (range: 20-75) presenting a total of 320 hernias: 140/230 (60.8%) were monolateral and 90 (39.2%) bilateral; 267/320 hernias (83.6%) were primary and 53 (16.4%) recurrent. We had no perioperative complications. After an average follow-up of 26 months (range: 1-40) the only postoperative complications we encountered were 6 seromas (1.8%) and 1 trocar-site haematoma (0.3%). None of the patients developed scrotal haematomas. None of the patients complained of immediate or subsequent paraesthesia or cruralgia. No recurrences have occurred to date. The mean operative time was 30 minutes for monolateral hernias (range: 15-45) and about 50 minutes for bilateral hernias (range: 30-75). This was true of both primary and recurrent hernias. Patients are usually discharged on day 1 postoperatively. In the absence of pain, working activities are resumed after 5 days and sports can be practiced after 10 days. In our experience, fibrin glue (Tissucol) is the best way of fixing the mesh during a transabdominal preperitoneal procedure. It is better than mechanical devices because, though guaranteeing prosthetic stability, it is completely non-traumatic and presents none of the problems of metal clips.

Abstract
Small bowel tumors are uncommon lesions that are infrequently suspected. We analyzed the clinical presentation, traditional and new diagnostic tools, surgical treatment, and survival in our experience. This was a retrospective review of 45 patients with small bowel neoplasm over a 20-year period. Preoperative diagnosis was made only in 17 cases (38%). One lesion was shown using a new diagnostic system: wireless capsule endoscopy (WCE). All patients underwent surgery. Mean 5-year overall survival for malignancies was 23%. Female sex and localized disease were positive prognostic factors for survival. Small bowel neoplasms must be considered in differential diagnosis in patients with abdominal symptoms, weight loss, and intestinal bleeding. Because the preoperative diagnosis rarely is made with traditional diagnostic tools, patients are seen late in the course of the disease, and the prognosis is poor. WCE is useful for identifying lesions earlier than by other diagnostic procedures.

Abstract
Morgagni-Larrey hernia is a congenital type of diaphragmatic hernia. It is quite uncommon, particularly when it occurs on the left side of the diaphragm. This is a report of a case of a large left-side diaphragmatic hernia through the foramen of Morgagni treated by laparoscopy. The hernia was repaired by incorporating and fixing a polypropylene double-filament mesh into the defect, leaving the sac in mediastinum. The patient recovered promptly after the hernia repair, and there was no recurrence or complaints 30 months after surgery. Our conclusion is that laparoscopically repairs of Morgagni hernias with a prosthetic material are a safe and effective treatment. A literature review also shows that laparoscopic techniques are the gold standard in diaphragmatic hernias repairs.

Abstract
CONTEXT Acute pancreatitis is related to drugs in 1.4-2% of cases. Estrogens are an uncommon but well-known risk factor of pancreatitis in women and men with pre-existing hyperlipidemia. CASE REPORT We report the case of a 37-year-old man with covert hypertriglyceridemia who developed a severe life-threatening pancreatitis strongly associated with estrogen therapy preparatory to sex change surgery, characterized by a massive triglyceride level, pancreatic insufficiency and multiple organ failure at the time of the diagnosis. Other causes of the disease were ruled out. CONCLUSIONS To our knowledge, this is the first description of severe necrotizing estrogen-induced pancreatitis in a male. Baseline abnormal triglyceride levels should be checked by physicians before starting estrogen therapy in women and men.

Abstract
Cell-mediated immunodeficiency, with Total and T lymphocytes count decrease, is well established in cancer patients and it predicts a poor prognosis and poor survival rates. Furthermore, major surgery induces a transient immunodeficiency, too. Nevertheless, cell-mediated immunity in pancreatic cancer, which has a very poor prognosis, has not been completely outlined. Aim of this study is to evaluate the cell-mediated IL-2 dependent immune status in operable pancreatic cancer patients and to compare it with other gastrointestinal tumors. One hundred and twenty-one cancer patients (22 pancreatic, 48 gastric and 51 colorectal), with a median age of 66 years (range 42-83), 55 males and 66 females, were enrolled. Total lymphocyte count and lymphocytes subset (T helper count - CD4+) were assessed preoperatively and on the 14th and 50th postoperative day. Results obtained were compared between the groups and related to nodal involvement (N0 versus N+). Colorectal and gastric cancer patients showed quantitative lymphocyte deficiency at baseline in 29% and 41% of cases, respectively. Fourteen days after surgery values below normal range were found in 44% and 54% (Total) and 53% and 67% (T helper), respectively. Recovery of postoperative surgery-related lymphocytopenia occurred late only in patients with normal count at baseline. According to regional nodal involvement (pN0/N+) T helper deficiency was significantly more frequent in patients with nodal involvement than in patients without. In pancreatic cancer, percentage of immunodepressed patients at baseline was higher compared to the other two groups (71%). Lymphocyte count was significantly different between pancreatic and gastric/colorectal cancer, reaching a statistical significance at baseline and on the 14th and 50th postoperative day. No differences of T helper deficiency were noted according to nodal involvement (N0 versus N+) neither at baseline nor in the postoperative period. In conclusion, the degree of immunosuppression varies among different tumor types: since initial stages of disease, immunodepression was significantly greater in pancreatic cancer which should be considered always a systemic disease even in early stages and indipendently from the nodal involvement and from tumor load.

Abstract
BACKGROUND Gastrointestinal carcinoid tumors are rare and little is known about factors related to prognosis in patients with carcinoid disease. Aim of this study is to determine the impact of clinical presentation variables on the management and survival. METHODS We have evaluated 31 consecutive patients with gastrointestinal carcinoid tu-mours who underwent surgical intervention at the I Department of Surgery of Milano-Bicocca University over 15 years (1985-1999). Tumor distribution, hormone production, prognostic factors and survival were analysed. RESULTS Carcinoid syndrome was the only clinical pattern diagnostic of carcinoid tumour. Most common symptoms were abdominal pain (64%), nausea and vomiting (48%). High levels of urinary 5-hydroxyindolacetic acid were significantly associated with carcinoid syndrome and metastatic disease. Tumor size, depth and gender were significant predictors of metastases. Age, gender, tumor size, metastatic spread and location were statistically significant predictors of death. CONCLUSIONS Clinical presentation was non specific except for those patients affected by carcinoid syndrome. Ten years overall survival was 43%, with 52% metastatic spread incidence. The extent of surgical resection should be modulated on patient related risk factors. Poor prognostic factors affecting survival were: age, gender, metastatic disease, depth of invasion and tumour size.

Abstract
We have shown that actively phagocytosing human polymorphonuclear leukocytes (PMN) float on top of the incubation medium when Oil Red O containing paraffin oil particles (density 0.8740) are used as the phagocytosable material. This implies that the quantitation of phagocytosis based on the recovery of Oil Red O in phagocytosing cells pelleted after centrifugation would be underestimated. We therefore prepared particles of progressively increasing density by mixing paraffin oil (density 0.8740) with silicon oil (density 1.0802). Cell flotation also occurred with paraffin oil-silicon oil particles and could be avoided only when the density of the particles used had reached 0.9952 g/cm3. Paraffin oil-silicon oil particles of a density sufficient to dissolve the dye Oil Red O were therefore used to quantitate both the initial rate of phagocytosis and the phagocytic capacity of human PMN. With this assay the initial rate of phagocytosis was found to be 400 micrograms paraffin oil-silicon oil/min/5 X 10(6) PMN, which is about 20 times higher than that reported for the same cell type using paraffin oil particles. The calculated maximum phagocytic capacity was 2.5 mg paraffin oil-silicon oil/5 X 10(6) PMN. The uptake of paraffin oil-silicon oil particles was sensitive to inhibitors of phagocytosis, such as N-ethylmaleimide, papaverine and cytochalasin B, in a dose dependent manner. The assay also permitted the detection of increased phagocytosis such as occurs in myeloperoxidase deficient PMN.
