We analyzed Radioisotope scan findings of 46 patients of thyroiditis which were proven pathologically at K.C.H. The results were as follows 1) 45 patients were female, one was male and average age of patients was 37 years old. 2) The lesion site was predominant in both lobe (67%) 3) Hashimoto's thyroiditis showed enlarged thyroid (85%) with cold nodule (20%), diffuse decreased activity (10%), while subacute thyroiditis was presented absent activity (53%), poor visualization (20%) or cold nodule (7%) 4) Radioisotope scan was valuable in evaluations function of thyroid gland and detection of lesion but there was a limit of pathological nature.

Cementifyng fibroma is one of the fibro-osseous lesions. All fibro-osseous lesions containing cementum are considered to be of periodontal membrance origin and is most common in the maxilla and mandible. Rarely, cementifying fibromas are seen in other craniofacial bone except jaw lesion. A diligent search in the available world literature show only two documentation of cementifying fibroma in the fronto-orbital bone. This case is third case but first in the frontal bone beyond orbit. The authors report a case of cementifying fibroma of the frontal bone in 12-year-old female patient.

Obtaining mutant animals is important for studying the function of a particular gene. A chemical mutagenesis was first carried out to generate mutations in C. elegans. In this study, we used ultraviolet-activated 4,5',8-trimethylpsoralen to induce small deletion mutations. A library of mutagenized worms was prepared for recovery of candidate animals and stored at $15^{\circ}C$ during screening instead of being made into a frozen stock library. In order to isolate deletion mutations in target genes, a polymerase chain reaction (PCR)-based screening method was used. As a result, two independent mutants with deletions of approximately 1.0 kb and 1.3 kb were isolated. This modified and improved reverse genetic approach was proven to be effective and practical for isolating mutant animals to study gene function at the organismal level.

This study was carried out to review and evaluate a total of 2,463 cases of human chromosomal analysis at Kwangju Christian Hospital from 1974 to 2004. We collected 2.0-3.0ml of human peripheral blood in heparized bottle. Then, we cultured it for 72 hours. We performed GTG-banding and chromosomal kayotyping analysis by Cytovision kayotyping system. Abnormal karyotypes were observed in 30.5% of the total cases (750/2,463). Autosome and sex chromosome anomalies were observed in 25.8% (635/2,463) and 4.7% (115/2,463) respectively. In a total of 2463 cases, there were 522 (22.4%) cases of Down's syndrome karyotype, and 67 (2.7%) cases of Turner syndrome. In conclusion, Down's syndrome has decreased after the end of the 1990s, but other (Turner syndrome et al.) chromosomal abnormal cases haven't decreased after the1970s.

The paper introduces a research on the W-band Millimeter Wave Radiometer(RADW92) through an airborne experiment. Microwave remote sensing images of part of the Yellow River and the WeiHe River are of fared. Analysis of factors influencing the image qualities as well as the resolutions to them are also included. The RADW92 is the first generation of Millimeter Wave Radiometer in China, which works with operating frequency 92 GHz, the bandwidth 2 GHz, the integration time 60ms, the system sensitivity 0.6k and the linearity better than 0.999. Cassegrain Antenna is designed for imaging by conically scanning. The result of the experiment suggested that RADW92 had been adequate for space use.
