Background: Colorectal cancer (CRC) is one of the most common malignancies of the gastrointestinal tract. The aim of this study was to assess the general knowledge of CRC in individuals living in Rasht, Iran, using a population-based cross-sectional telephone survey. Materials and Methods: A total of 1557 participants between 18 and 80 years of age were interviewed using random sampling from the telephone directory. Knowledge of risk factors, symptoms, diagnosis, and prevention of CRC was assessed using a validated questionnaire. Results: The mean knowledge level of the 1,557 respondents (average age 46 y) was $13.5{\pm}4.29$ (maximum possible score = 26), and 46.4% (722/1,557) of the subjects achieved grades lower than the mean score. The mean scores for knowledge of symptoms and risk factors were $3.97{\pm}1.83$ (range: 0-7) and $5.17{\pm}1.65$ (range: 0-9), respectively. Older age, higher education, and employment were significantly associated with better scores for recognition of risk factors and warning symptoms. The majority of subjects correctly identified weight loss (70.2%; 1,093/1,557) and rectal bleeding (63.3%; 986/1,557) as symptoms of CRC, and that smoking (85.9%; 1,337/1,557) and a low-fiber diet (73.4%; 1,143/1,557) were risk factors. Approximately half of the subjects noted increasing age, genetic background and fried food as other risk factors. A considerable number (54.8%; 853/1,557) identified colonoscopy as a screening method for detecting CRC in asymptomatic patients. However, a third of the subjects in the target group for screening (${\geq}50y$) were not interested in undergoing screening, primarily due to a lack of symptoms. Conclusions: Our results suggest that the knowledge of CRC is poor among the public, and therefore greater attempts should be made to increase awareness. Public education emphasizing the risk factors and symptoms of CRC, as well as the importance of regular screening regardless of the presence of symptoms, may help to reduce CRC morbidity and mortality.

Carcinoembryonic antigen (CEA) levels were measured in the serum of 35 normal control subjects and 179 cases of various benign and malignant gastrointestinal diseases. Malignant gastrointestinal tumors include 69 cases of stomach cancer, 24 cases of hepatoma and 33 cases of colorectal cancer. Benign gastrointestinal diseases include 29 cases of peptic ulcer and 24 cases of liver cirrhosis. The results were as followings: 1) Mean serum CEA level in normal control subjects was $6.9{\pm}3.3ng/ml$ and there was; no difference in mean serum CEA level between age and sex difference. 2) In malignant gastrointestinal tumors, mean serum CEA level in colorectal cancer, hepatoma and stomach cancer, were $54.3{\pm}88.9ng/ml,\;62.1{\pm}99.7ng/ml$ respectively. Serum CEA level showed positive rate of 67% in colorectal cancer, 63% in hepatoma and 62% in stomach cancer. There was no difference in mean levels and positivity of serum CEA between these 3 malignant tumor groups. 3) Positivity of serum CEA was 61% in malignant gastrointestinal tumor group in spite of 37% in benign gastrointestinal disease group. In both mean level and positivity of serum CEA, stomach cancer was much higher than peptic ulcer. But there was no difference in mean level and positivity of serum CEA level between hepatoma and liver cirrhosis. 4) In hepatoma serum CEA level showed positive rate of 62.5% and alpha-feto protein showed a rate of 58.3%. 5) Mean serum CEA levels in patients with cancer in rectal, cecal, sigmoid colon, ascending: colon and descending colon were $73.7{\pm}106.7ng/ml,\;69{\pm}84.8ng/ml$, $15.7{\pm}9.1ng/ml,\;7.5{\pm}10.6ng/ml$ and 4.0ng/ml respectively. Positive rate of serum CEA showed 86% in sigmoid. colon cancer, 68% in rectal cancer and 66% in cecal cancer. 6) In considering of histological background, there was no correlation between the degree of differentiation of tumor cell and the serum CEA level in colorectal cancer. According to Duke's classification, the mean serum levels of CEA were $8.8{\pm}11.4ng/ml$ in group A, $15.3{\pm}16.0ng/ml$ in group B and $68.5{\pm}101.5ng/ml$ in group C respectively. Positivity-of serum CEA in group A, Band C were 40%, 50% & 69% respectively. So there was significant correlation between the degree of elevation of serum CEA and tumor extension.

Small intestinal transit (SIT) has often been regarded as an index of pathophysiological state of postoperative ileus (PI) in rats. The reliability of SIT as an index of PI was examined in the present study. PI was induced via abdominal surgery (i.e., laparotomy with evisceration and manipulation) in rats. For one group of PI-induced rats, SIT of a charcoal test meal was measured. When necessary, the physical state (i.e., severity and site of distension) of the gastrointestinal (GI) tract in each rat was visually examined. For another group of PI-induced rats, abdominal X-ray radiographs were obtained after introducing the barium sulfate suspension. The abdomen was then opened and the physical state of the GI tract was visually examined. The SIT was decreased in most of the PI-induced rats, and the GI distension was observed, with substantial intersubject variations, in all of the PI-induced rats. However, no linear relationship was evident between the SIT and the severity of GI distension (e.g., at 20 h after PI induction). Instead, the severity and site of GI distension could be monitored by the X-ray radiology. Therefore, the use of SIT as an index of PI should be substantially limited.

For the purpose of wide application of Korea Ginseng Radix (KGR) as a tonic and medicinal drug, bibliographical study on Ginseng Radix (GR) was done about its herbal and pharmacological effects known so far. Herbal effect of GR was studied in 28 classical books including Shennongbencaojing(신농본초경), the oldest herbal book in oriental medicine and also its pharmacological effects was compared with its herbal effect. In bibliographical study 38 kinds of efficacies of GR were referred in those books, for example, in fields of gastrointestinal tract, heart, psychology, body fluid, hormone and respiratory tract in order from statistical analysis. GR was chiefly used for supplementing Qi, vital energy in oriental medicine. However, experimental study on respiratory diseases was not reported except lung cancer yet, while GR was used for the treatment of asthma mostly mixed with other herb in oriental medicine. So far research with GR was performed chiefly for isolation of constituents as saponins and evaluation of its efficacy experimentally by KGTR (Korea Ginseng Tobacco Research Institute). From the above studies, to make KGR used widely than before, I suggest study with KGR should be done according to oriental principles such as Qi and tasters and combination theory between herbs excepting typical analytical research with saponins.

The chitosan-coated liposomes (chitosomes) were designed to improve the stability in the gastrointestinal (GI) tract and to enhance the efficacy for oral drug delivery of liposomes. The phosphatic acid (PA)-incorporated anionic liposomes were surface-coated with water soluble chitosan (WSC) by electro-ionic interaction. The shape of the chitosomes observed by transmission electron microscopy (TEM) was spherical in all the formulations and the coating layer by WSC could be founded through TEM images. The mean size and the zeta potential values of the chitosomes increased significantly with depending on the content of WSC added for coating the liposomes. The stability of the chitosomes in the GI tract was confirmed through the change of relative turbidity of the liposomal suspension. The plain liposomes (plasomes) suspension without adding WSC clearly showed the change of relatively turbidity in simulated gastric fluid (SGF), while the change degree of turbidity of the chitosomes in the SGF decreased as increasing of WSC content added for coating liposome. In the 5-CF release study from the plasomes and chitosomes, the plasomes released >90% of the initial 5-CF content at 4 h of release measurement. In contrast, the chitosomes released below 40% of initial content of 5-CF. In conclusion, these results indicate that the chitosomes can be used as a potential carrier for effective oral drug delivery.

Graft-versus-host disease (GVHD) is a common complication of allogeneic stem cell transplantation (allo-SCT). However, a similar syndrome has been reported in autologous stem cell transplantation (ASCT) as well. The target organs of GVHD in ASCT are the skin, liver and gastrointestinal (GI) tract, which are consistent with those in allo-SCT. Histologic findings from the skin and the mucosa of the GI tract also show similar features. Here we describe a case of autologous GVHD involving the skin of a patient who underwent ASCT for multiple myeloma. In this patient, the response to a total prednisone dose of 0.5 mg/kg/day was unsatisfactory, and the patient required more intensive and prolonged immunosuppressive therapy with slow tapering.

The extranodal nasal NK/T-cell lymphoma was formerly known as lethal midline granuloma due to its most common clinical pattern like a destructive midline facial tumor. It often spread to other extranodal sites, such as skin, soft tissue, testis, upper respiratory tract, and gastrointestinal tract etc. For this reason, the term of extranodal NK/T-cell lymphoma, nasal type is preferred. Its disease entity may have a prominent admixture of inflammatory cells and necrotic tissues, further causing difficulty in diagnosis. A 44-year-old man was visited to our clinic with complaints of dysphagia and odynophagia during six months. He underwent three times punch biopsies and then, two times incisional biopsies. Finally, He was diagnosed as extranodal NK/T-cell lymphoma, nasal type involving oropharynx and supraglottis. We report an extremely rare case of extranodal NK/T-cell lymphoma, nasal type occurred in oropharynx and supraglottis with a brief review of literature.
