OBJECTIVE: To investigate new signal transduction cascade through integrin, FAK and ERK in the suppressed cell proliferation by GnRH-I and -II. METHOD: Human endometrial cancer cells (HEC1A) were cultured under the following condition: DMEM/F12 (10% FBS). GnRH-I and -II were treated time (0, 5, 10, 15, 20, 30 min; 100 nM) and dose (10 nM or 100 nM; 20 min) dependent manner according to experimental purposes. Cell proliferation was measured using [3H] thymidine incorporation assay. Immunoblotting was utilized to detect proteins. RESULTS: GnRH-I and -II inhibited proliferation of HEC1A cells and induced expression of integrin beta3. Phosphorylation of FAK and ERK were induced by GnRH-I and -II. CONCLUSION: GnRH inhibited cell proliferation via the expression of integrin and FAK, ERK phosphorylation.

A case of adenocarcinoma of cystic duct associated with GB empyema is presented. A 72 year old male was admitted to Kwangju Christian hospital because of abdominal pain in right upper quadrant for 4 days. He underwent explolaparotomy under the impression of GB empyema or GB cancer. For seeking causative factor of GB empyema, serial sections of cystic duct and mapping were performed. We can find adenocarcinoma of cystic duct in the specimen removed at cholecystectomy. The criteria for disgnosis of cystie duct carcinoma which was outlined by Farrar. These criteria are; 1) The growth must be restricted to the cystic duct, 2) There is no neoplastic process in the gall bladder, hepatic and common bile duct. 3) Histopathological examination must be comfirm carcinoma. Here we report a case of adenocarcinoma of cystic duct associated with GB empyema with brief review of Literature.

Miescher syndrome comprises congenital acanthosis nigricans, hypertrichosis, failure to thrive and short stature, dysmorphism especially of the jaws and oral cavity, insulin-resistant diabetes mellitus, and a characteristic general appearance. This report concerns a rare case of 12-year-old girl having insulin resistant diabetic mellitus with Miescher syndrome. The relevant literature was reviewed.

The relationship between the intestinal histopathology and number and position of intraepithelial lymphocytes (IEL) was observed chronologically in the small intestine of rats experimentally infected with Metagonimus yokogawai. Fifteen Sprague-Dawley rats were orally infected each with 3,000 metacecariae, and 3 were kept uninfected for controls. Three rats each were sacrificed on the day 5, 10, 15, 24 and 70 post-infection (PI) and samples of the small intestine, 5 cm, 10 cm, 20 cm and 70 cm posterior to the pylorus were taken. The samples were processed routinely and stained with Giemsa. The intestinal histopathology was severe during the day 5-15 PI and characterized by villous atrophy, crypt hyperplasia, and decrease of villus/crypt height ratio. After the day 24 PI, the intestinal lesions showed some tendency of recovery. The number of IEL increased at the early stage of infection, but decreased thereafter to a lower level than that of controls, with progression of the pathological changes. Then, the IEL number began to increase again after the day 24 PI. In control rats, the great majority of the IEL were located at the basal region of the epithelium. During the early stage of infection, however, a considerable proportion of IEL was found to have moved to the intermediate or apical region of the epithelium. From the above results, it is suggested that the change of IEL number and position during the course of M. yokogawai infection should be closely related to the progression and recovery of the intestinal histopathology.

Fatigue is a universally common word. The subject has been studied in different disciplines, but the basic concept of the term still remains unidentified. It becomes especially important for the medical communications between nurses and clients. Based on the framework outlined by Walker and Avant(1995), this analysis attempts to clarify and examine the symptoms of fatigue. The attributes of fatigue identified in this paper were exhaustion, weighted psychological burden, shortage in capacity or lack of energy, shortage incapacity(motivation and excitement), and imbalance of energy. Therefore, the definition of fatigue refers to a subjective feeling from various internal or external stresses. The consequences of fatigue bring reduced capacity and imbalance of energy. The symptoms show a homeostatic disability or shortage of capacity (physical, psychological, environmental and physiological factors). A precise understanding of 'fatigue' will be utilized in defining the causes and measuring outcomes. Also, it will enhance the effective medical communications with clients and nurses. In conclusion, more work is needed to develop objective measurement and effective nursing intervention.
