Aspergillosis, caused by infection with Aspergillus fumigatus and less commonly by other Aspergillus species, is a prevalent and costly respiratory disease of poultry, In a flock of chicks, the number of birds, 4∼5 months old, had become gradually emaciated and subsequently died. Gross necropsy revealed multiple granulomatous masses on the abdominal serosa. The masses, 4∼15 mm in size, were attached on mainly intestinal wall. Also, the smaller masses in size were on mesentery and pancreas. However, only a few small white nodules were scattered throughout liver and lung in few samples. Microscopically, the mass were granulomatous with a central area of necrosis containing numerous septate, branched fungal hypae consistent with Aspergillus sp. These were surrounded by macrophages, giant cells, lymphocytes and fibrous tissues. Nodular lesions of liver and lung were seemed to spread hemotogenously from intestine and the possible route of infection was speculated by oral. This report is a Aspergillus-induced granuloma limited to the serosa of abdominal cavity, especially of intestinal wall.

Biocompatible and biodegradable hydrogels based on carboxymethyl cellulose(CMC) and polyethyleneglycol(PEG) were prepared far physical barriers for preventing surgical adhesions. These interpolymeric hydrogels were synthesized by a gamma irradiation crosslinking technique. The 1Scmxl.Scm of cecal serosa and adjacent abdominal wail were abraded with bane burr until tbe serosal surface was disrupted and hemorrhagic but not perforated. and the serosa of tbe cecum was sutured to the abdominal wall in 5mm apart from the injured sire. The denuded cecum was covered with either CMC/PEG hydrogels or solution from CMC/PEG hydrogel. Control rat serosa was not covered. Two weeks later. the rats were sacrificed and adhesion was scored on a 0-5 scale. No treatment showed the significantly higher incidence of adhesions than either CMC/BEC hydrogels or solution from CMC/PEG hydrogel. In conclusion, these studies demonstrate that CMC/BEG hydrogels have a function of prevention of intra abdominal adhesion in a rat model.

Fibrinopurulent peritonitis and abdominal abscesses associated with Streptococcus (S.) equi subsp. zooepidemicus is reported in a 1-year-old female thoroughbred horse. The horse died after showing 5-day history of the cold, severe abdominal distention, abdominal breathing, hyperthermia, anorexia, and loss of intestinal sound. At necropsy, several liters of turbid yellowish green fluid were seen in the abdominal cavity. Yellowish creamy and fibrinous or bloody materials were presented on the serosa of various abdominal organs that were intensively adhered with each other. Spleen and mesenteric lymph node were remarkably enlarged. Affected lobes of the lung showed severe congestion, hemorrhage and doughy consistency. Histologically, the lung showed hemorrhagic pneumonia with diffuse congestion and edema. Severe diffuse fibrinopurulent peritonitis with Gram-positive bacterial cocci and adjacent fibrosis were showed in the serosa of various abdominal organs such as liver, spleen, stomach, and intestine. And multifocal abscess pouches were presented in the granulation tissue of abdominal viscera. S. equi subsp. zooepidemicus was isolated from the peritoneal swab, abdominal organs, and lung. Hematogenous dissemination of bacteria from hemorrhagic pneumonia is proposed as the route of infection in this case.

This study was carried out to prevent the abdominal re-adhesions in dogs. Two randomized groups of dogs were subjected to scratch the ileal serosa. Routine abdominal closure was performed on two groups. Second laparotomy was performed one month later for the scoring of the abhesion formation. The adhesions were separated physically after the scoring of the adhesions. In control goup saline was instilled into abdomen and in treated group 1% sodium carboxymethylcellulose(SCMC) solution was instilled into abdomen before the abdominal closure. Third laparotomy was performed another month later to evaulate the adhesions. Reduced adhesion formation following the instillation of 1% SCMC was reported. 1% SCMC is recommended to prevent the re-adhesions as well as adhesions.

Background: We aimed to investigate whether the tumor free distance (the distance between the uterine serosa and the tumor at its deepest point) is useful in surgical staging and in predicting prognosis. Materials and Methods: Data from patients who underwent complete surgical staging for endometrial cancer between January 2006 and June 2011 were reviewed retrospectively. All demographic findings, surgical stages, histological type and grade, myometrial invasion, lymphovascular space invasion as well as abdominal cytology, cervical, adnexal, and omental involvement, and lymph node metastasis were recorded. The relations between myometrial invasion and tumor free distance from uterine serosa with prognostic factors were investigated. Results: Seventy patients were included in the study. Sixty-four (91.5%) had endometrioid type cancers and forty-four (62.9%) were grade 1. The deepest myometrial invasion was less than 1/2 in 42 patients (60%). In 18 patients (25.8%) lymphovascular invasion was noted. Eight (11.4%) were found to have cervical involvement, five (7.1%) had adnexal involvement and in 4 cases (5.7%) the peritoneal washings included malignant cells. Four patients had pelvic and one para-aortic node metastasis. We recognized that an invasion of more than 1/2 was correlated significantly with lymphovascular space involvement, histological grade, positive abdominal washing cytology, nodal and cervical involvement, but not with adnexal involvement. Tumor-free myometrial thickness was negative and statistically significant correlated with surgical stage, histological grade, lymphovascular space involvement, positive abdominal washing cytology, cervical and adnexal involvement. The importance of tumor-free myometrial thickness in determinating the lymphovascular space invasion was found to be highest in terms of sensitivity and specificity when crossing the ROC curve at 11 millimeters. Conclusions: Depth of myometrial invasion is more valuable for predicting lymph node metastasis than tumor-free myometrial thickness. The tumor-free myometrial thickness provides a better prediction for adnexal involvement.

A 12-year-old female small-clawed Asian otter (Anoyx cinereus) with a one-week history of anorexia, chills, and abdominal distension was found dead. Grossly, yellowish-brown turbid fluids accumulated in abdominal cavity of the otter, and yellowish thread-like fibrinous materials were found on the surface of abdominal organs. Several variable sized yellowish-white crystalloids were scattered on the medullary space of kidneys. Histologically, diffuse serositis (peritonitis) characterized by the fibrinous exudates, thickened serosal capsule and the swelling of mesothelial cells were observed in the serosa of liver, spleen, stomach, and intestine. Multifocal necrosis, hemorrhage, infiltration of macrophage, and brown pigments were presented in the liver. Isolated bacteria from ascites and fibrinous materials in abdominal visceral surface were white, smooth and convex with characteristic mousy odor on blood agar plate. These bacteria were confirmed as Pasteurella (P.) multocida type A by polymerase chain reaction analysis. Based on the gross examination, histopathologic findings and bacterial experiments, this otter was diagnosed as severe peritonitis associated with P. multocida and necrotic hepatitis.

A 36-year old Korean woman consulted a clinic for a regular gynecological examination, and a mass was noticed in her pelvis. She was referred to the Asan Medical Center, Seoul where transvaginal ultrasonography confirmed a pelvic mass exceeding 10cm in diameter. She received total abdominal hysterectomy and bilateral salpingoophorectomy, and a borderline serous neoplasm with micropapillary features involving the left ovary and right ovarian serosa was histopathologically confirmed. In addition, a section of a nematode with numerous eggs was found in the parenchyma of the left ovary. The worm had degenerated but the eggs were well-preserved and were identified as those of Enterobius vermicularis. She is an incidentally recognized case of ovarian enterobiasis.

This case report is about hemolymph nodes found in a dairy cow whose function is still not fully elucidated. A 4-month Holstein cow presented severe respiratory symptoms and hematochezia for a while with respiratory acidosis and metabolic alkalosis. Coccidiosis was diagnosed and treated immediately, but the cow died from respiratory acidosis and metabolic alkalosis. At necropsy, no abnormal appearance in thoracic and peritoneal organs was observed, but hemolymph nodes were observed being multifocally stuck on omasum serosa and the subcutaneous fascia of abdominal region, and the larger dark red lymph nodes were found along the omasum great curvature. Microscopically, lymphoid depletion and lymphadenitis in the lymph nodes were examined to point systemic infection, and in the hemolymph node, multifocally demarcated pale lesions with macrophage infiltration and fibrin deposition nearby subcapsular sinus. In subcapsular sinus of the hemolymph node, rod to linear gram-negative bacteria were found. Through this study, we might conclude that the hemolymph node is involved in pathogen phagocytosis.
