Retinal function and histologic changes following intravitreal injection of indocyanine green in a rabbit model.

The aim of this animal study was to investigate the effects of intravitreal injection of indocyanine green (ICG) applied in macular hole surgery on retinal functional, morphology, and histologic changes. Eighteen (18) New Zealand albino rabbits were divided equally into three groups (6 rabbits in each). In Group A, both eyes of each rabbit were vitrectomized by perflouropropane gas compression. One (1) month later, 0.1 cc of different doses of ICG was injected into the vitreous in the left eyes. In the right eyes, 0.1 cc of balanced salt solution was injected intravitreally, allowing them to serve as control eyes. In Group B, the same doses of ICG were injected intravitreally. ICG was washed out by fluid-fluid exchange 3 minutes after injection. In Group C, the same doses of ICG were injected intravitreally in nonvitectomized eyes. Scotopic and photopic electroretinogram (ERG) recordings and indirect ophthalmoscopy examinations were performed to detect any functional and morphologic changes. Rabbit eyes were enucleated 4 months after ICG injections to observe histologic changes. Significant decreased of scotopic and photopic ERG amplitude and marked histologic changes were noted in eyes injected with 0.5 mg/cc and 0.1 mg/cc of ICG in nonvitrectomized eyes (Group C). In vitrectomized eyes (Group A), decreased scotopic and photopic ERGs and mild histologic changes were noted in eyes injected with 0.5 mg/cc, but no histologic changes were noted in eyes injected with 0.1 mg/cc. There was a transient, mild decrease in scotopic and photopic ERGs and no morphologic changes were noted in the eyes with fluid-fluid exchange (Group B). The toxicity of intravitreous ICG is dose- and time-dependent. ICG at 0.5 mg/cc, with short exposure time, is recommended in macular hole surgery.

Characteristics and trends in incidence of inflammatory bowel disease in Taiwanese children.

BACKGROUND AND PURPOSE: Although chronic inflammatory bowel disease (IBD) is rare in Asian children, increasing numbers of pediatric patients with chronic IBD worldwide have been noted in recent years. This study was conducted to delineate the trend in incidence and clinical patterns of childhood IBD in Taiwan. METHODS: All children admitted to National Taiwan University Hospital (NTUH) between 1979 and 2000 who met the criteria for IBD, Crohn's disease (CD), ulcerative colitis (UC), probable CD (PCD), or indeterminate colitis were included. The clinical features and outcomes were analyzed retrospectively. Incidence was calculated using cases of chronic diarrhea during the same period of time as the risk population. RESULTS: IBD was diagnosed in 17 children (9 females and 8 males, aged 2 months to 18 years) during the study period. Six (35%) of these children had UC, 9 (53%) had CD, and 2 (12%) had PCD. The cumulative incidence of CD during 1979-1995 was 0.85%, and increased to 2.6% during 1996-2000 (p < 0.001), while the incidence of UC did not change significantly between these periods (from 0.85% to 0.99%, p = 0.16). The median interval from onset to diagnosis was 7.7 months. Eighty percent of patients had moderate to severe disease activity at diagnosis. The follow-up duration ranged from less than 1 year to 20 years, with a mean of 4.3 years. Two patients were lost to follow-up. Eighty six percent of patients responded to treatment, and 80% of patients had inactive to mild disease activity when re-evaluated at the end of 2000. CONCLUSION: There has been a marked recent increase in the incidence of childhood CD in Taiwan but the rate of childhood UC has remained unchanged. Eighty percent of cases of childhood IBD responded well to treatment.

POLO-LIKE KINASE1 GENE EXPRESSION AND ITS CLINICOPATHOLOGICAL SIGNIFICANCE IN GASTRIC CARCINOMA

Objective To clarify the polo-like kinasel （PLK1） expression in human gastric cancer tissue and its clinicopathological significance in gastric carcinoma. Methods PLK1 expression in 60 cancer tissues and their corresponding noncancerous tissues from gastric cancer patients was measured by both real-time quantitative RT-PCR and western blot assay, lmmunohistochemistry was used to detect PLK1 protein expression in eighty-nine paraffin-embedded samples. Results The PLK1 mRNA and protein expression level in the 60 fresh cancer tissues was significantly higher than that in noncancerous tissues （ P 〈 0. 0001, P = 0. 031 respectively）. In paraffin-embedded samples, apart from its increased expression level, PLK1 was found to be in both cytoplasm and nucleus, double-site location only occurred in poor-differentiated cancer, PLKI expression intensity was associated with tumor dif- ferentiation （ P = 0. 03）, invasion （ P = 0. 032 ）, TNM stage （ P = 0. 019） , ki67 expression （ P = 0. 011 ）. The patients with negative PLK1 expression had better survival rate than that with positive PLK1 expression （ P =0. 0292 ）. Conclusion PLK1 may have clinicopathological value in tumor diagnosis, and may become another new biomarker and therapeutic target for gastric cancer.
