Current evidences have expended the concept that chronic inflammation might play a crucial role in the development and progression of colorectal cancer. For instance, chronic ulcerative colitis (UC) is associated with a 10- to 40-fold increased risk of developing colorectal cancer (CRC) compared to the general population. However, the specific mechanistic link between chronic inflammation and carcinogenesis in colon has not been integrated into molecular understanding. In this current review, we will provide an update on the molecular pathogenesis of colitis-associated colorectal cancer, focused on 1) the differences of molecular mechanism between the colitis-associated colorectal cancer (CAC) and the sporadic colorectal cancer (SCC), 2) the plausible and contributive role of chronic inflammation in colon carcinogenesis, and 3) lessons learned from colitis-associated animal model. Understanding of molecular pathogenic mechanism underlying the colitis-associated colorectal cancer will facilitate the development of novel treatment strategies for prevention of colitis-associated colorectal cancer.

Analysis of endothelial morphology by computer assisted digitizer and image analysis program provides very useful indices of cell shape and size which appear to correlate to the monolayer's functional status. To study the influences of the Alizarin red S staining, which is commonly used in animal experiments of corneal endothelium and vital staining, on the morphologic characteristics of corneal endothelium, morphometric data(density, area, coefficient of variation, perimeter, shape factor, hexagonality, lengths) obtained by specular microscopy of the endothelium are compared to data obtained by Alizarin red S staining of the endothelium of the excised cornea. Mean endothelial cell area was measured as 389.58 +/- 37.14 micrometer2, density was 2588 +/- 251 cells/mm2. The corresponding values measured after Alizarin red S staining, cell area was 407.42 +/- 45.3 micrometer2 and density was 2484 +/- 294 cells/mm2. But no significant differences were noted in comparing all morphometric data obtained by staining to that obtained from specular microscopy. Therefore, Alizarin red S staining combined with cell morphometric analysis could provide valuable data in a cornea which lacks clarity limits or precludes specular microscopy.

BACKGROUND: It has been well known that patients with diabetes mellitus are prone to cutaneous infections, but whether superficial mycoses are truly more prevalent in diabetic patients is still controversial. OBJECTIVE: The purpose of this study was to determine the true prevalence of superficial mycoses in diabetic patients as comparing with non-diabetic, non-immunocompromised individuals. METHODS: We examined for evidence of superficial fungal disease in 137 diabetic patients and compared it with 146 non-diabetic non-immunocompromised ones. Potassium hydroxide preparations and fungus cultures were performed from all suspected lesions. RESULTS: Superficial mycoses were more common in diabetic patients(50%) than controls(31%) (p=0.0004), especially in the age group of 4th and 5th decades9p=0.011). The duration of diabetes mallitus or blood sugar levels were not significantly correlated with the prevalence of superficial mycoses.The organism most commonly isolated was Trichophyton rubrum in both groups(53% vs 79%) and Candida albicans was more prevalent in diabetic patients(34% vs 7%). More than 2 kinds of superficial mycoses were mose common in diabetic patients than controls(38% vs 16%). CONCLUSION: This study shows that the prevalence rate of superficial mycoses in diabetic patients is higher than that in controls and the in controls and the duration of diabetes mellitus or blood sugar levels were not significantly correlated with it.

Gastrointestinal hemangioma is a relatively uncommon benign vascular tumor that can occur anywhere in the gastrointestinal tract. It is the second most common vascular lesion of the colon and a clinically important entity because of the possibility of massive hemorrhage when complicated. In gross appearance, hemangioma presents variously as a pedunculated, subpedunculated, or flat elevated lesion similar to a submucosal tumor. A typical case of hemangioma is relatively easy to diagnose because the lesion presents as translucent blue-purple vessels under the mucosa. However, it can be difficult to diagnose in some cases, especially if it does not have its usual characteristic color or is covered with normal mucosa. We incidentally found a colonic hemangioma that had the unusual appearance of a pedunculated polypoid lesion with normal mucosa. It was misdiagnosed as a pedunculated polyp with a long, thick neck and treated by using an endoscopic mucosal resection.

Gastric tuberculosis is a rare disease and the diagnoeis of gastric tuberculosis is based on either positive histological or bacteriological study. We experienced a case of gastric tuberculosis with pleural effuaion in 59 year-old woman, diagnosed by the histological study of the endoscopic biopsy specimen. Follow up endoscopic finding revealed marked improvement of gastric lesion after anti-tubercadoua medication. We reported the case with review of literature.
