In order to confirm whether the migrating larvae of parasites could carry pathogenic organisms into liver and cause hepatitis, a series of experiments has been carried out. Clonorchis sinensis: Recovery rate of larvae in the abdominal cavity of rabbits: One to seven days after the administration adolescariae were recovered from the abdominal cavity in less than l percent of the total number of metacercariae given. Generally, 1-6 larvae were found from each animal which was given 900-1,000 metacercariae, though many larvae were already found in the common bile ducts or remained still in intestine. Fate of Clonorchis sinensis in abdominal cavity: The young or mature worms which were introduced directly into the abdominal cavity were examined l5, 32, 40 and 42 days after the inoculation. Several larvae were found on the surface of liver in four animals. All the worms on the surface of the liver were dead and the biopsied liver tissues on the area where the worms were attached showed no pathological changes. Two of them were between bile duct and liver tissue but pus cell infiltration surrounding them was observed. In every case, pus cell infiltration was found in the peripheral portion of the liver and pus nodules on the surface of intestine and mesentery. The nodule in the intestinal wall contained the eggs of Clonorchis sinensis. Two worms in the abdominal cavity were still alive. From the above results it is suggested that the larvae of Clonorchis sinensis were capable of penetrating the intestinal wall and reaching the organs in the abdominal cavity and surviving for l5-42 days, but they were unable to penetrate the organs. No bacterial flora appeared from the lesion by culture method. Fate of Clonorchis sinensis which was inoculated into the peripheral region of liver: Small abscess was observed at the same area. Microscopically, the area became edematous and the vessels in the peripheral region were dilated. The parasites became necrotic and amorphous. Pathologically the lesions appeared as eosinophilic masses and neutrophile leukocytes were infiltrated surrounding the masses. In some cases, the dead worms were found apart from the original place of inoculation but no leukocyte infiltration was found. There was linear infiltration between the original site and the portion where the dead worm was found. The distance from the capsule varied from 0 to 4 mm. Sometimes, the eggs of Clonorchis sinensis were also found. In all cases, there were no living worms in liver tissues and hepatic ducts. In all case,. the bacteriological examination was negative. Do clonorchis sinensis transfer the microorganism? Five adult worms of clonorchis sinensis were incubated in the saline solution containing Staphylococcus aureus. The intestinal contents of these worms were cultured in the Nutient-agar plate and examined by Methylene Blue and Gram's stain. The area of liver tissue where the Clonorchis sinensis were inoculated showed no inflammatory changes after the 3 days of inoculation but no living Staphylococcus aureus was found in the culture media with which the pieces of liver tissues were smeared. Hookworm: Cutaneous infection: Four to eight days after the cutaneous infection of Ancylostoma caninum, the mice were sacrificed. Grossly, there was no abnormal finding in liver. The pieces of liver tissues were smeared on the Nutrient-agar plate, and cocci were found in four out of six examined. The microorganism were confirmed as the same species of Diplococcus pneumoniae which were grown in the hookworm culture media. Oral infection: 1,000 filariform larvae of Ancylostoma caninum were given orally. 24 hours later, the mice were sacrificed and the pieces of liver tissue were smeared on the Nutrient-agar plate. After 50 hours at 36 C, the bacterial colonies were examined bacteriologically. Staphylococcus albus was found from two out of four samples. Grossly there was no abnormality on the surface of liver, but microscopically there were spots like microabscesses which were infiltrated by leukocytes. The larvae were also found from other portions of liver tissues and they were surrounded by yellow colored material. In another experiment, a combination of Ancylostoma duodenale and Staphylococcus aureus was fed to mice. The mice sacrificed five days after the oral administration of Ancylostoma duodenale cultivated in the media containing Staphylococcus aureus. The liver pieces were examined routinely. The larvae cultivated in normal tap water which contained no Staphylococcus aureus was used as control. In the experimental mouse, the cocci appeared in the liver. Pathologically, microabscesses infiltrated with neutrophile leukocytes were found, but there was no manifestation of inflammatory change due to Staphylococcus aureus. There was only mechanical trauma due to the larvae penetration. Haemorrhage appeared only where the larvae were found.

Nurse education is undergoing a process of transition. Nurses worldwide are working towards achievement of higher levels of education and training through an improved education system. Current trends and innovations in nursing education are emerging to prepare more nurses and to deliver education to students across geographical boundaries while taking into consideration their work and family responsibilities. The current trends and innovations in nursing education range from full time face-to-face interactions to distance education programmes. Teaching approaches such as blended learning, online or e-Learning have provided nurses with an avenue for continuing education for development and progression in their career pathways. Every nurse aspires to reach her highest potential. While the current trends and innovations in nursing education provides the flexibility for nurses to continue learning and upgrade their professional qualifications, there are issues to be considered in catering to the needs of the bottom billion nurses. An exploration of related issues will include views from different perspectives, such as that of the institution/provider, instructor/facilitator and student/learner involved in the development and implementation of the related education programmes.

Central diabetes insipidus is a rare disorder that can result as a consequence of diverse etiologies, including malformations, autoimmune, infiltrative(e.g. neoplastic or histiocytosis) or traumatic processes, as well as mutations in the gene encoding arginine vasopressin. Idiopathic central diabetes insipidus is a diagnosis of exclusion, one that has been made less frequently through the decades. Idiopathic central diabetes insipidus in children and adolescent requires a frequent follow-up regimen using serial brain MRI and CSF examinations especially if an isolated pituitary stalk thickening or loss of a hyperintense signal in the posterior lobe is observed. Also, so-called "idiopathic" central diabetes insipidus warrants close follow-up to determine the etiology, especially if anterior pituitary hormone deficiencies are detected. We report a case of idiopathic central diabetes insipidus with growh hormone deficiency and loss of a hyperintense signal in the posterior lobe. He is a 13 years old. We are scheduled to follow-up with serial contrast enhanced brain MRI and CSF evaluation for the early detection of an evolving occult hypothalamic-stalk lesion.

Cholelithiasis is defined as the presence of stones within the lumen of the gallbladder or in the extrahepatic biliary tree. Cholecystitis, secondary to gallstones, is a common surgical disorder in Korea. Detailed microscopic descriptions, particularly the ultrastructural changes, of these diseases were not available. The goal of this study was to identify the ultrastructural alterations of gallbladder epithelium in cholecystitis with and without a stone, according to the degree of severity of inflammation, and the nature of the stone. The gallbladders of the control group, and cholecystitis cases without stone and with stone were fixed and examined with routine stain, special stain, immunohistochemical stain and trans-mission electron microscopy. The number and the volume density of the mucin containing secretary granules were not significantly increased in the calculous cholecystitis cases compared with those of the acalculous cholecystitis cases. Major findings were that the calculous cholecystitis cases showed a markedly reduced total lysosome area and volume density of the lysosome compared with those of the acalculous chole-cystitis cases. The differences between the mucin secretary granules and lysosomes, according to the degree of severity of cholecystitis and the natures of gallstones, were statistically not significant.
