Abstract
Most cases of peritoneal dissemination of colorectal cancers are from T3 or T4 tumors. A 61-year-old woman was admitted for examination of a positive fecal occult blood test. Colonoscopy showed an ascending colon tumor that was diagnosed as an adenocarcinoma with massive submucosal invasion. Imaging modality revealed numerous nodules throughout the abdominal cavity. Peritoneal dissemination of the ascending colon or ovarian cancer and pseudomyxoma peritonei were considered in the preoperative differential diagnoses, and laparoscopic ileocecal resection was performed. Intraperitoneal observation revealed numerous white nodules in the peritoneum, omentum and Douglas fossa. Both the nodules and tumor were diagnosed as mucinous carcinoma based on a pathology report. The tumor invasion depth was limited to muscularis propria, and no regional lymph node metastasis was detected. Peritoneal dissemination of the ascending colon cancer was considered. We report a rare case of multiple peritoneal dissemination of T2 colorectal cancer without lymph node metastases.

Abstract
Inguinal bladder hernia (IBH) is a rare condition that is difficult to diagnose preoperatively. 16% of IBHs are diagnosed postoperatively due to bladder injury and leakage. Preoperative diagnosis of IBHs is important to lessen postoperative complications. Transabdominal preperitoneal approach can significantly reduce the risk of bladder damage.
Introduction Inguinal bladder hernia (IBH) is a rare condition that is difficult to diagnose preoperatively based only on physical examination; 16% of IBHs are diagnosed postoperatively due to complications. Presentation of case We report the case of a 56-year-old man who presented with left inguinal swelling and increased frequency of urination since eight years. Physical examination demonstrated a 6 × 4 cm non-reducible left inguinal bulge with mild tenderness on palpation. Computed tomography revealed a left inguinal hernia containing a portion of the urinary bladder. He was diagnosed with IBH and transabdominal preperitoneal (TAPP) repair was performed. We confirmed a left internal inguinal hernia and incised the peritoneum from the outside of the left inguinal ring. The preperitoneal space was dissected toward the Retzius space, and the prolapsed bladder was examined. The adhesion with the surroundings was carefully dissected and the bladder was reduced into the abdomen. Indigo carmine was injected through a urinary catheter, which confirmed that no bladder damage had occurred. After the mesh was positioned to cover the myopectineal orifice, it was fixed to the Cooper’s ligaments, interior side, lateral side, and ventral side. The postoperative course was uneventful, and the patient is now free of symptoms and recurrence two months after surgery. Conclusion TAPP repair is a useful treatment for IBH. Preoperative diagnosis of IBH is important to lessen postoperative complications.

Abstract
Cytogenetic investigations in bone marrow from animals treated with isoniazid (INH) were performed in seven different laboratories according to a standard protocol. The experiments were carried out in the Chinese hamster, the mouse, and the rat. In short-term studies INH was administered twice at an interval of 24 h in doses of 5, 25, and 125 mg/kg, and the animals were sacrificed 6, 12, 24, and 48 h after the second dose. In long-term studies doses of 25 and 125 mg/kg were administered thrice weekly for 12 weeks. As a rule, each group consisted of at least four animals, and 100 metaphases per animal were counted. Statistical analysis of the data showed that the incidence of chromosomal aberrations including gaps lay in the critical range for two groups in one laboratory and was significantly higher than in the control in three groups in another of the seven laboratories. From the results of both the short-term and the long-term studies in all laboratories, however, it may be concluded, that isoniazid does not induce gross chromosomal aberrations.
