The authers performed long coloaofiherscopy with barium enema study on 134 cases, of coloreatal diseasea, who had been admitted to the department of Internal Medicine, Kwangiu Christian Hospital from July 1984 to Aupist 1986, The results were following: 1) Among 134 cases of colonoacopy, abnormal findings were 70 cases (52.2%) and normal findings 64 cases (47.8%). 2) among 70 cases of colonoscopic abnormal findings, nonspecific inflammatory colitis were 27 cases, colon tuberculosis 15 cases, colon and rectal cancer 14 cases, colon polyps 8 cases, ulcerative colitis 3 cases, internal hemorrhoid 2 cases, sigmoid diverticular 1 case. 3) The cases in which the findings of barium contrast enema were compatible with those of colonoscopy were 84 cases (62.7%), not compatible 50 cases(37.3%). There were not compatible with findings in 4 cases of colon cancer (10 cases), 7 cases of colon tuberculosis (15 cases), 4 cases of colon polyps (8 cases), 1 case of ulcerative colitis (3 cases). 4) The insertion ratio to ileocecal valve was 79.1%. The rate of correct approach by a colonoscopy to the lesion site shown at barium contrast enema was 94.1%

Gastric neurofibroma is rare and its exact incidence is unknown. We experienced a case of solitary gastric neurofibroma. A 49-year-old woman was admitted because of hematemesis and melena. Neither cafe-au-lait spots in skin nor superficial tumor were found. Gastrofibroscopic examination and UGI series showed a 3 * 4 cm sized luminal protruding mass with adjacent bridging mucosal fold and cental ulceration on the anterior wall of lower body. Mass excision was performed. Grossly, the mass was 4.5 * 3.0 * 2.0 cm sized, well circumscribed submucosal tumor with homogenous cut surface, Microscopically, each of the tumor cells had oval shaped nucleus and spindle shaped cytoplasm. Nuclear atypism and frequent mitosis were not observed. We report a rare case of solitary gastric neurofibroma with review of the literatures.

Cell replacement therapy using neural progenitor cells (NPCs) following ischemic stroke is a promising potential therapeutic strategy, but lacks efficacy for human central nervous system (CNS) therapeutics. In a previous in vitro study, we reported that the overexpression of human arginine decarboxylase (ADC) genes by a retroviral plasmid vector promoted the neuronal differentiation of mouse NPCs. In the present study, we focused on the cellular mechanism underlying cell proliferation and differentiation following ischemic injury, and the therapeutic feasibility of NPCs overexpressing ADC genes (ADC-NPCs) following ischemic stroke. To mimic cerebral ischemia in vitro , we subjected the NPCs to oxygen-glucose deprivation (OGD). The overexpressing ADC-NPCs were differentiated by neural lineage, which was related to excessive intracellular calcium-mediated cell cycle arrest and phosphorylation in the ERK1/2, CREB, and STAT1 signaling cascade following ischemic injury. Moreover, the ADC-NPCs were able to resist mitochondrial membrane potential collapse in the increasingly excessive intracellular calcium environment. Subsequently, transplanted ADC-NPCs suppressed infarct volume, and promoted neural differentiation, synapse formation, and motor behavior performance in an in vivo tMCAO rat model. The results suggest that ADC-NPCs are potentially useful for cell replacement therapy following ischemic stroke.

This study describes pathological, immunohistochemical, and bacteriological findings in adult dogs and fetuses naturally infected with Brucella (B) canis. A total of 42 dogs including 40 dogs and 2 aborted fetuses were examined. The most common gross lesions in infected dogs were swelling of lymph nodes and spleen. The testes showed marked swelling with multifocal to diffuse reddish discoloration. The most significant histopathological lesions were observed in the placenta. Placental trophoblasts were markedly hypertrophied due to the accumulation of intra-cellular gram-negative bacteria. Lymphocytic inflammation of varying severity was observed in the reproductive organs such as male testis, epididymis, and prostate gland and female uterus. Strong immunolabelling was observed in the cytoplasm of most trophoblasts in the placental tissues using immunohistochemistry. However, immunohistochemical staining did not demonstrate any organisms in other organs of dogs and fetuses. B. canis isolates were most frequently obtained from the whole blood (82.5%) and superficial inguinal lymph node (77.5%) in both sexes. In addition, the isolation rate was higher in male genital organs than in those of females. Hence, management of male dogs is most important because infected dogs can play a role as carriers.
