Objective To investigate homografting vascular endothelial progenitor cells(EPCs)for preventing restenosis formation of carotid artery in New Zealand white rabbit models.Methods EPCs of New Zealand white rabbits were isolated,confirmed and expanded though the injured carotid arterial endothelium of rabbit model induced by dilatation with a 2.5 F balloon;and then EPCs were transplanted into the injured endothelium of the cells transplantation group(n=13,3 of them were transplanted with fluorencently-labeled- EPCs),while equal volume of saline without EPCs was injected into the injured endothelium in the control group(n=8).Histopathology was performed at 4 days after transplantation for the 2 rabbits,with fluorencently-labeled-EPCs.All of the rest remained rabbits were killed 4 weeks later for histological examinations.Results The histopathological slides showed that the fluorescence-positive expression existed in the injured endothelium 4 days after transplantation.At 4 weeks after the EPCs transplantation,there were less restenosis and less vascular wall thickening in the rabbits of cells transplantation group than those of the control group(P＜0.01).Conclusion The local interventional homografting heterogeneous endothelial progenitor cells can prevent restenosis after the carotid artery angioplasty in New Zealand White rabbit model.

PURPOSE: This study was aimed to evaluate the effect of the deproteinated bovine bone powder (DBBP) coated with calcium phosphate (Ca-P) on osseous regeneration in the calvarial bone defect of rat. MATERIALS AND METHODS: The DBBP (Control group, n=6) and the Ca-P coated DBBP (Experimental group, n=6) were grafted in the critical sized calvarial bone defect (8 mm) of rat weighing 250 g. The animals were sacrificed at 1, 4 week. The biopsy specimens were decalcified with 5% formaldehyde and embedded in paraffin. The rats were sacrificed at 8 week received tetracycline (1 week), calcein blue (4 week), and alizarin red (7 week), and the biopsy specimens were taken. The specimens were embedded in methylmethacrylate and ground to 10 micrometer thin sections were made. All of the specimens were stained with H & E and Masson's trichrome and examined under light microscope. The specimens at 8 week were examined under fluorescent microscope. RESULTS: In the Control group, the grafted DBBP was surrounded with connective tissue, and osteoblasts were observed partially around the grafted particles at 1 week. At 4 week, some osteoid was observed and, new bone formation was observed at the periphery of grafted materials at 8 week, In the Experimental group, some osteoid was seen at the periphery of the grafted Ca-P coated DBBP at 1 week, and osteoblast and newly formed bone were observed around the grafted materials. At 8 week, newly formed bone was observed at the periphery of the grafted materials. CONCLUSION: These results suggest that Ca-P coated DBBP group was more and faster than DBBP group in new bone formation and Ca-P could contribute to enhance bone formation in the critical sized calvarial bone defect of rat.

A umbilical omphalomesenteric duct polyp is the result of incomplete closure of the omphalomesenteric duct, which connects the midgut with the yolk sac of the embryo. It may be associated with underlying embryologic anomalies such as Meckels diverticulum and umbilical enteric fistula, the complications of which may at times be fatal. This rare malformation should be clinically discerned from persistent granulation tissue or pyogenic granuloma. Histologically, it shows a polypoid lesion consisting of ectopic gastrointestinal epithelium with the appearance of gastric, intestinal, or colonic mucosa. We report a case of an umbilical omphalomesenteric duct polyp in an 8-year-old male patient, who had had a bright-red polyp on the umbilicus from the age of 1 month and had not had any other types of underlying abnormalities.

Mucoepidermoid carcinoma of lung are rare carcinoma arising from the submucosal glands tissue of the proximal tracheobronchial tree. The carcinoma can be divided into low grade and high grade varienties. The most important factors in the prognosis include histological grading and the ability to achieve a complete surgical resection. We experienced a case of high grade mucoepidermoid carcinoma in pulmonary tuberculosis patient of 67 years old male who has been suffered from left chest pain for several weeks. He was not treated and died seventeen months later.

In this retrospective study, 412 patients who had a curative resection with a lymph node dissection of higher level than D2 for gastric cancer at the Kwangju Christian Hospital from 1985 to 1991 were reviewed to analyze the dependence of their survival rate on lymph node metastasis results obtained by evaluating various metastatic patterns and on the spectrum of tumors(location, depth of invasion, size, and histologic type). The results are as follows: 1) Positive metastatic lymph nodes were found in 258(62.6%) of the 412 patients. When it came to the metastatic frequencies of each lymph node, No. 6 was involved in 40% of the cases(165 cases), No. 4 in 21.6%(87 cases), No. 3 in 20.1%(83 cases), No. 5 in 15%(62 cases), No. 8 in 14.3%(59 cases), No. 1 in 9.7%(40 cases), No. 7 in 8.9%(37 cases), and No. 9 in 8.2%(34 cases), which shows relatively higher metastatic frequencies for the perigastric lymph nodes than for the others. The 5-year survival rates for metastasis of various lymph nodes were 33.3% for No. 10, 20.4% for No. 3, 20% for No. 2, 20% for No. 13, 17.5% for No. 6, 16.6% for both No. 12 and 15, 15.7% for N0. 4, 12.9% for No. 5, 11.7% for N0. 9, 10.8% for No. 7, 8.4% for No. 8, 10% for both No. 1 and No. 11, 5.5% for No. 14 and 0% for No. 16. 2) When it came to the dependence of the metastatic frequencies of lymph nodes on the location of the gastric cancer, cancers in the lower third of the stomach showed the highest metastatic frequency in No. 6(39%), followed by No. 3(16.8%) and No. 4(16.2%) in that order. In the case of gastric cancer in the middle of the stomach, No. 6 showed the highest frequency at 48.6% followed by No. 3(26.3%), No. 4(23.6%), No. 5(17.1%), No. 8(17.1%), and No. 9(9.2%) in that order. In the case of gastric cancer in the upper third of the stomach, No. 3 showed the highest frequency at 47.6% followed by No. 1(47.6%), No. 4(38%), No. 6(23.8%), No. 5(19%), and No. 7(9.5%) in that order. This showed that in all lacations of gastric cancer, lymph node metastases were primarily observed among the perigastric N1 node group. 3) As the tumor invasion into the stomach wall grew deeper, metastases of the lymph nodes of N2 or higher groups increased. There was a significant difference in the metastatic frequencies of the lymph nodes between the proper muscle and the serosal layer. The survival rate dropped to a remarkable degree when the tumor invasion was deeper than the serosal layer. 4) Poorly differentiated adenocarcinomas were more frequently metastasized to the regional lymph nodes than well differentiated ones, and the metastasis extended to nonperigastric lymph nodes. The poorer the differentiation was, the lower the survival rate became. 5) The larger the size of the tumors was, the higher the lymph node metastatic frequency grew, reducing the survival rate. 6) When patients were in advanced stages of gastric cancer, the survival rate dropped considerably. 7) Based on the results mentioned above in which tumor invasion into the lymph nodes of N2 or higher groups were often observed and in which there were significant differences in the prognosis, we conclude that a gastrectomy with extensive lymphadenectomy at least up to the second node group(D2) might be the procedure of choice for advanced gastric cancer in order to improve the survival rate.
