A mixture of OK-432 powder and an ointment base, lanolin, was applied to mouse abdominal skin. After application of the mixture of 5 KE OK-432 and 0.2g lanolin, the leucocyte count and IL-b content in the abdominal cavity increases to up to 3.6 x 10(6) cells and 1.4 ng, respectively. INF-gamma content in the cavity after application of a mixture of 10 KE OK-432 and 0.2 g lanolin also increases, although not after application of the 5 KE OH-432 mixture of dorsum subcutaneous injection of a saline solution of 5 KE OK-432. These results indicate that an application of OK-432 mixed in lanolin to the mouse abdomen is able to exert an influence on the immunomodulatory effect in the abdominal cavity. The concentrations of IL-6 in serum after applying the ointment mixture, and subcutaneous of intraperitoneal injection of the saline solution of 5 KE OK-432, were <20, 370, and 430 pg/ml, respectively. After application of the ointment mixture of 5 KE OK-432, serum IL-6 did not increase. IL-6 levels in the abdominal cavity after 5 KE OK-432 ointment of subcutaneous injection increases to up to 1.4 and 2.1 ng/cavity. From these results, the immunomodulatory systemic response of OK-432 brought about by applying OK-432 ointment to the abdominal skin is lower than that brought about by injecting OK-432 subcutaneously. Therefore, it is thought that application of OK-432 ointment might be most suitable for potentiating local immune response.
An overgrowth of pathogenic organisms occurs following rat heterotopic small bowel transplantation. This study assessed whether the bacterial microflora return to normal following subsequent orthotopic transposition of the graft. After 14 days the heterotopic graft was placed into continuity following resection of 15 cm of the host midintestinal loop. Quantitative and qualitative analyses of the intraluminal bacteria were performed studying the resected host intestine, the heterotopic graft at 14 days, and the graft 14 days after transposition. A group of normal rats were used as controls. An overgrowth of Staphylococcus epidermidis evident in the heterotopic graft at 14 days returned to a more normal bacterial profile following orthotopic transposition. These findings suggest that early interposition of a small bowel graft into an orthotopic position may prevent an alteration in the small bowel ecology toward potentially pathogenic organisms capable of translocation.
HISTORY AND CLINICAL FINDINGS: A 66-year-old woman was known to have had cholecystolithiasis for at least 4 years. Laparoscopic cholecystectomy was performed at another hospital where histological examination surprisingly revealed middle-grade differentiated carcinoma of the gall-bladder (pT2, G2). A nodular metastasis of the gall-bladder carcinoma was noted on the abdominal wall 3 months later and excised. Lymph-vessel carcinomatosis was already present. The patient again noticed a tumour in the right mid-abdomen and a further tumour was palpated in the epigastrium 5 months after the operation. INVESTIGATIONS: Laboratory and tumour-marker (CEA, CA 19-9) tests were unremarkable, while sonography and computed tomography were highly suspicious for abdominal wall metastases in the epigastrium and right mid-abdomen. TREATMENT AND COURSE: Both metastases were excised. Laparotomy revealed tumour recurrence in the old gall-bladder bed, as well as extensive peritoneal carcinoma. Two months after the operation she developed jaundice, caused by tumour compression of the choledochal duct. An expanding stent was inserted into the stenosed section of the duct. The patient died 13 months after the first operation from the underlying malignancy with multiple liver metastases and malignant ascites. CONCLUSIONS: Indications for minimally invasive surgery in malignant tumour should be narrowly defined. Because tumour seeding is possible after laparoscopic cholecystectomy with incidentally found carcinoma extensive re-excision should be performed.
