We studied the expressions of E-cadherin, MMP-7 and CD44V in colorectal cancer and their corresponding normal mucosa using RT-PCR. From the 26 patients whom a com parative study of clinical and histopathological data is available, MMP-7 and CD44V were significantly enhanced in cancer and their metastatic tissues, compared with their normal mucosa. E-cadherin did not reveal any difference between cancer and normal mucosa. The relashionship between these genes and colorectal cancer development can not be confirmed by this study, however CD44v and MMP-7 may be associated with metastasis of colorectal cancer.

It is commonly believed that the branchial anomalies are persistent remnants of the embryologic branchial apparatus. These anomalies are originated from branchial cleft and most commonly involved in second branchial deft. Clinically they present palpable mass, discharge from fistula, recurrent infection due to obstruction of Gstula tract. As respiratory symptoms, they may present hoarseness, preceeded by or associated with upper respiratory infection. However, it has not been reported that they caused airway obstruction in newborn infants. Wc experienced a case of the fourth branchial deft cyst in a 2 day old infant who showed respiratory difficulty due to airway obstruction.

Craniofacial clefts are rare among facial anomalies with an incidence of 1.5 to 5 per 100,000 births, and 1 per 100 cases of cleft lip and palate. The Tessier No. 7 clefts are unusual lesions that result from failure of the embryonic mandibular and maxillary processes to properly fuse and form the corners of the mouth. We experienced a case of Tessier No. 7 craniofacial cleft in a 1 day-old female patient who presented with a macrostomia and auricular malformation. The diagnosis was established by clinical and radiographic findings. A brief review of literature was made.

The influence of normal late pregnancy on insulin action and insulin secretion was studied in the Sprague-Dawley female rats. On 20th day after mating, intravenous glucose tolerance test(IVGTI) was performed in non pregnant control and pregnant rats. As results of IVGTT, glucose disappearance rate was not significantly different in both groups, but secretory response of insulin was significantly(p<0.05) increased in pregnant rat. And the ratio of insulin/ .glucose was significantly higher in pregnant rats, which means existence of insulin resistance. These insulin resistance was overcomed by increased secretory response of pancreatic insulin. Insulinogenic index( A insulin/glucose - 5 min) was highly significantly (r=0.62, p<0.01) correlated with progesterone concentration. Glycogen level and amounts of "C-glucose incorporated into glycogen after IVGTT were significantly(p<0. 05) decreased in the liver, but were not changed significantly in soleus. Glycogen synthase activity of soleus and liver was not differ significantly in the both groups. Insulin binding at varying concentrations of insulin to crude membrane of pregnant liver was not significantly different from control. In conclusions, although these pregnant rats were normal glucose tolerance due to increased secretory response of insulin, that was correlated with progesterone concentration, pregnant rat had insulin resistance. The mechanisms of insulin resistance were not related to defect of insulin binding phase and glycogen synthase, but suggest pre-receptor and/or postreceptor phase.

40 cases of bile duct carcinoma gathered over a 6-year period at Kosin Medical College were reviewed and theirclinical and cholangiographic findings were as follows: 1. There were 29 males and 11 females (the ratio of men towomen, 2.6:1) ranging from 37 to 74 years of age. The majority (70% of cases) were in 4th & 5th decades. 2.Clinical symptoms and signs: jaundice in 95%, RUQ or epigastric pain in 75%, pruritus in 52.5%, dark urine in 35%,weight loss in 32.5%, fever and chills in 22.5%, clay colored stool in 12.5%, and palpable mass in 12.5%. 3.Lab,findings: elevated serum total bilirubin(above 20.0mg% in 45%, 10.0-19.0mg% in 22.5%, 5.0-9.9mg% in 20%,1.3-4,9mg% in 5%), elevated alkaline phosphatase in 95%. Clonorchiasis were noted in 17.5%. 4. Histologic findingswere adenocarcinoma in most cases. 5. The location of bile duct carcinoma were common hepatic duct in 35%, commonbile duct in 32.5%, porta hepatis in 12.5%, junction with cystic duct in 10% and diffuse form in 10%. 6. In 33cases, PTC or post-operative cholangiographic examination were done. And the most frequent findings weredilatation of the proximal bile duct and abrupt narrowing or complete obstruction of distal lumen. In 27cases(82%), complete obstruction of bile duct was noted. Attempts were made to analyze the type of obstruction:Constricted type in 39%, Nipple type in 18%, round or flat type (smooth or slightly irregular) in 15%, andserratd type in 9%. Incomplete obstruction were noted in 6 cases(18%). Among them, abrupt narrowing of lumen wasnoted in 9% and diffuse narrowing in 9%. 7. ERCP was done in 7 cases. Findings were constricted type in 42.6%,constricted and slightly irregular type in 14.3%, downward convexity in 14.3%, diffuse irregular narrowing in14.3% and intraluminal filling defect in 14.3%.

BACKGROUND: More than 90% of acute stroke patients have measurable cardiovascular sequelae, but we have been often overlooked in formal discussions of treatment. If we estimate the incidence of myocardial injury in patient with spontaneous SAH, we may figure the possibility of cardiac dysfunction in such patients. This study was designed to investigate the incidence of myocardial injury in patients with spontaneous SAH using cardiac troponin I(cTnI). METHODS: A prospective single emergency center study was performed to determined preoperative incidence of unrecognized cardiac injury in patients suffering spontaneous SAH. We include the spontaneous SAH patients who underwent serum measurements of the cardic troponin I immediately upon admission last six month period. ECG, CK, CK-MB and myoglobin were also performed at admission. We excluded the spontaneous SAH patients who had past history of myocardial ischemia and ECG abnormality. RESULTS: Fifty-two patients(34 females, 18 males) with spontaneous SAH were studied prospectively. 18 patients(34.6% of the total study population) had cTnI level above 0.5ng/ml. ECG was performed in 52 patients and was abnormal in 15 of the 52 patients(28.8%). CONCLUSION: The measurement of cTnI has provided physicians with a myocardial marker that has a cardiac sensitivity for cardiac injury equal to that of CK-MB yet with greater specificity. So, cardiac troponin I is useful to estimate the incidence of myocardial injury in patients with spontaneous SAH. And we may estimate the possibility of cardiac dysfunction in such patients. This knowledge will hopefully aid in the care and improve the outcome.

CD44 is a cell adhesion molecule with numerous isoforms created by mRNA alternative splicing. Expression of CD44 variants has been suggested to play a potential role in tumor progression and metastasis. We designed primers CD44V, CD44V6/7, CD44R1 and CD44V6-10 to analyze and compare the roles of each CD44 variants. Expressions of CD44 variants were investigated in normal colonic mucosa, the lymph nodes which was histopathologically free of cancer cell, and cancer tissues of 44 human colorectal cancer patients by RT-PCR method. The expression of CD44V was observed in 28 out of 39 (71.8%) tumors and 7 out of 11 (63.6%) N1 normal regional lymph nodes, and CD44V6/7 was observed in 28 out of 39 (71.8%) tumors and 9 out of 11 (81.8%) N1 normal regional lymph nodes. The expressions of CD44V and CD44V6/7 were most frequently observed compared with any other CD44 variants. In normal colonic mucosa, the expression of CD44 variants are low but in cancer tissue and its regional lymph node, the expression of CD44V and CD44V6/7 were significantly higher and more frequent than any other CD44 variants (p<0.05). These results suggest that CD44V and CD44V6/7 can be a molecular marker for colorectal cancer and its micrometastasis to the regional normal lymph node.
