  • Background: Ischemic injury and the rejection process are the main reasons for graft failure in tracheal transplantation models. To enhance the acceptance, we investigated the influence of mesenchymal stem cells (MSCs) on tracheal allografts. Methods: Extracted tracheal grafts from New Zealand white rabbits were cryopreserved for 4 weeks and orthotopically transplanted (control group A, n=8). In group B (n=8), cyclosporin A (CsA, 10 mg/kg) was injected daily into the peritoneal cavity. In group C (n=8), MSCs ($1.0{\times}10^7$ cells/kg) from the same donor of the tracheal allograft, which had been pre-cultured for 4 weeks, were infused intravenously after transplantation. In group D (n=8), MSCs were infused and CsA was injected daily. Four weeks after transplantation, gross and histomorphological assessments were conducted for graft necrosis, measuring the cross-sectional area of the allograft, determining the degree of epithelization, lymphocytic infiltration, and vascular regeneration. Results: The morphologic integrity of the trachea was retained completely in all cases. The cross-sectional areas were decreased significantly in group A (p=0.018) and B (p=0.045). The degree of epithelization was enhanced (p=0.012) and the lymphocytic infiltration was decreased (p=0.048) significantly in group D compared to group A. The degree of vascular regeneration did not differ significantly in any of the groups. There were no significant correlations among epithelization, lymphocytic infiltration, and vascular regeneration. Conclusion: The administration of MSCs with concurrent injections of CsA enhanced and promoted epithelization and prevented lymphocytic infiltration in tracheal allografts, allowing for better acceptance of the allograft.

  • Purpose: : The purpose of this study was to evaluate the intrauterine insemination (IUI) success rate and to define the variables for predicting success. Methods: The secondary data analysis was used with data collected from infertile females who underwent IUI in Fertility and IVF (In Vitro Fertilization) clinics, who benefited from the 'National Medical-aid Program for ART (assisted reproductive technology) in 2016', in which the data of 34,920 IUI cases were retrospectively reviewed. The primary outcome measure was the clinical pregnancy rate in elderly and young infertile females. Data were analyzed by descriptive statistics, χ2 test and logistic regression. Results: The pregnancy rate was 12.1% (2,095 cases) in elderly infertile females and 15.6% in young infertile females (2,758 cases) (χ2 = 87.90, p< .001). Using the logistic regression analysis, clinical pregnancy was positively associated with the ovulatory factor (OR= 1.48, p< .001) and male factor (OR= 1.19, p< .05) in elderly infertile females. It was positively associated with the ovulatory factor (OR= 1.30, p= .001) and the peritoneal cavity factor (OR= 0.58, p< .05) in young infertile females. Conclusion: Our results indicate that the pregnancy rate in young infertile females was higher than that in old infertile females, and the IUI is the effective option in pregnancies in all ages with infertility due to the ovulatory factor. Additionally, further studies are necessary to fully describe pregnancy experiences for all the infertile females.

  • Multisystem organ failure resulting from gram negative bacterial sepsis is associated with high morbidity and mortality in surgical neonates. There are differences in the clinical characteristics of organ failure in neonates and adults. The purpose of this study is to identify the differences and determine the order of organ failure between baby rats and adult rats after induction of gram negative sepsis. Fifty baby rats less than 30-day-old and another 50 adult rats more than 2-month-old were divided into control group (G1) and experimental group (G2). The G1 consisted of 10 baby- and 10 adult-rats, and the G2 consisted of 40 babies and 40 adults. E. coli ($10^8/mL$ per 100g of body weight) were injected into the peritoneal cavity in G2 and same amount of saline was injected in G 1. Blood samples were obtained before injection, 24 hour, 48 hour, 72 hour and after death. WEC, platelet, $PaO_2$, $PaCO_2$, total bilirubin, BUN, creatinine, albumin and abdominal wall thickness were measured to evaluate the sequence of organ failure. The mortality was 55.0 % in G2-babies and 32.5 % in G2-adults. In baby rats, microvascular, hematologic and renal failure appeared within 24 hours after injection and pulmonary failure followed. Pulmonary, renal and liver failure developed within 24-48 hours in adult rats; however, microvascular failure did not appear until they were moribund. Thrombocytopenia, hypoalbuminemia, increased BUN and generalized edema was the earlist sign of sepsis in baby rats.

  • Pneumoperitoneum, Pneumomediastinum, subcutaneous emphysema and a pneumothorax are some of the mechanical complications of bronchial asthma. The incidence of pneumoperitoneum during an attack of acute asthma is rare. The pathogenesis is free gas track from the overdistended alveoli, through the bronchovascular sheaths to the mediastinum. If the high pressure is maintained, air can escape retroperitoneally into the abdomen and burst into the peritoneal cavity. A 43-year-old woman was admitted due to a severe asthma attack. She was required endotracheal intubation and AMBU(air mask bag unit) ventilation. Immediately after these procedures, pneumoperitonewn, pnewnomediastinwn, and subcutaneous emphysema developed. She was treated with mechanical ventilation and medical therapy. The pneumoperitonewn was resolved after 27days. Here, we report this case with the review of the relevant literature.

  • A 3-year-old intact mixed hunting dog was referred to Gyeongsang Animal Medical Center with the clinical signs of vomiting, dyspnea, anorexia. The dogs had traumatic history that wounded at abdominal wall during the wild boar hunting 2 week ago. The dogs was diagnosed as extrahepatic biliary tract obstruction (EHBO) secondary to traumatic hernia. Diagnosis was based on radiographic features of a diaphragmatic hernia on survey radiography, dilated bile duct in abdominal ultrasonography and complete recovery due to the return of displaced organs into the peritoneal cavity and repair of the diaphragmatic rent. Diagnostic imaging and surgical intervention may result in a favorable outcome in dog with post hepatic obstruction secondary to diaphragmatic hernia. This case emphasizes the strangulation of bile duct by diaphragmatic rupture could be the cause of EHBO.

  • This study was performed to investigate the effect of Bunsimgieum on antitumor effect after sarcoma-180 cells transplantation into peritoneal cavity or left groin and immune responses on the depressed immunity induced by methotrexate in mice. The Bunsimgieum extract of 10mg/kg was orally administered 14 days for antitumor effects and 21 days for immune responses. 50% inhibitory concentration($IC_{50}$) of SUN-1, SUN-C4, and SUN-396 cancer cell, mean sunvival days and body weight of tumor bearing mice, and growth of tumor mass for antitumor effect; delayed type hypersentivity, hemagglutinin titer, hemolysis titer, rosette forming cells, natured killer cell activity, lymphocyte transformation, productivity of interleukin-2, and phagocytic activity for their immune responses were measured in ICR mice. Significance in antitumor effect is noted in the enlongation of mean life days and inhibition of tumor growth(p<0.01, respectively). Significance of immune responses is also noted in hemolysis titer, lymphocyte transfumotion, IL-2 productivity, phagocytic activity, and natural killer cell activity at E/T ratio 100:1(p<0.01, respectively). Significant in rosette cell formation was seen at dosage of 20mg/kg(p<0.01). However, Difference of body weight as antitumor effect, delayed type hypersensitivity, and hemagglutinin titer were not shown significantly. According to the above results, it could be suggested that Bunsimgieum has prominent antitumor and immunity enhancing effect.

  • The development of antibody titers and crossreaction between Sarcocystis and Toxoplasma were investigated by means of IF A test and ELISA in pigs experimentally infected with $1.5{\times}10^6$ S. suicanis sporocysts and 10,000 T. gondii oocysts, respectively. The intact and soluble Sarcocystis antigens were prepared from the bradyzoites harvested by peptic digestion of infected pork. The intact and soluble Toxoplasma antigens were prepared from the tachyzoites in mouse peritoneal cavity. IgG antibodies in pigs infected with Sarcocystis and Toxoplasma, respectively were detected first at 2 weeks post infection on both IF A test and ELISA. The antibody titer to Toxoplasma reached its maximum at 6 weeks post infection and decreased thereafter. The antibody titer to Sarcocystis reached its maximum terminally. The cross-reaction titer in pigs infected with Toxoplasma against Sarcocystis antigen was up to 1 : 16 in IFA test and up to 1 : 32 in ELISA. The titer in control group was below 1 : 4 in both reactions.

  • Objective: Endometriosis is a chronic debilitating inflammatory condition characterized by the presence of endometrial tissues outside the uterine cavity. Pelvic soreness and infertility are the usual association. Due to the poor effectiveness of the hormone therapy and the high incidence of recurrence following surgical excision, there is no single effective option for management of endometriosis. Mesenchymal stem cells (MSCs) are multipotent stromal cells studied for their broad immunoregulatory and anti-inflammatory properties; however, their efficiency in endometriosis cases is still a controversial issue. Our study aim was to evaluate whether adipose tissue-derived MSCs (AD-MSCs) could help with endometriosis through their studied anti-inflammatory role. Methods: Female Wistar rats weighting 180 to 250 g were randomly divided into two groups: group 1, endometriosis group; established by transplanting autologous uterine tissue into rats' peritoneal cavities and group 2, stem cell treated group; treated with AD-MSCs on the 5th day after induction of endometriosis. The proliferative activity of the endometriosis lesions was evaluated through Ki67 staining. Quantitative estimation of interferon γ, tumor necrosis factor-α, interleukin (IL)-6, IL-1β, IL-10, and transforming growth factor β expression, as well as immunohistochemical detection of CD68 positive macrophages, were used to assess the inflammatory status. Results: The size and proliferative activity of endometriosis lesions were significantly reduced in the stem cell treated group. Stem cells efficiently mitigated endometriosis associated chronic inflammatory reactions estimated through reduction of CD68 positive macrophages and the expression of the proinflammatory cytokines. Conclusion: Stem cell therapy can be considered a novel remedy in endometriosis possibly through its anti-inflammatory and antiproliferative properties.

  • Ascites is the accumulation of fluid in the peritoneal cavity, and it is generally allied with liver disease like cirrhosis of the liver. The ascites is commonly associated with liver cirrhosis, malignancy, or cardiovascular disease today. The liver cirrhosis is the most significant cause of ascites in developed countries as per the available data. In the modern medicine system, the treatment includes the restriction of sodium intake, use of diuretics, and paracentesis done in severe cases. There are many side effects of synthetic chemical diuretics, and their long-term use is not recommended. The alternative medicine like Unani system of medicine provides natural diuretics and drugs which also have protective effects on kidney, liver and other internal organs. It is well known in all drug systems that the prognosis is poor in ascites, but the use of Unani herbal medicines can minimize the side effects caused by synthetic chemical diuretics. The natural herbs used for the management of ascites have fewer side effects as compared to synthetic drugs. The natural drugs can be used for longer duration and provide some dietary supplement which improves the quality of life. This review addressed the thorough treatment of ascites by natural diet and medications.

  • Pseudomyxoma peritonei (PMP) is a rare clinical syndrome characterized by profuse jelatinous materials in the abdominal cavity and pelvis with mucinous implants on the peritoneal surface. There are some studies for serum tumor markers, including carcinoembryonic antigen (CEA), carbohydrate antigen 19-9 (CA19-9) and carbohydrate antigen 125 (CA125), to assess the risk of recurrence following cytoreductive surgery and intraperitoneal chemotherapy. However, rare cases were reported about recurrence with increasing serum CEA levels. Herein, we report a case of recurrence of PMP according to serially elevated serum CEA.
