1989년 1월부터 1992년 12월 사이에 대장암으로 근치적 절제술을 시행받은후 추적조사가 가능한 45명의 환자를 대상 대장암조직의 Hematoxylin-Eosin염색을 통하여 apoptotic body를 광학 현미경하에서 400배율 하에서 관찰하여 암세포 100개당 평균개수를 세었으며 TUNEL 방법을 이용하여 면화학적염색을 통하여 염색정도를 판정을하여 대장암에서 아포토시스의 정도를 판정하여 다음과 같은 결과를 얻었다. Dukes병기 A 일 때 apoptotic body가 평균 1.93개, B 일 때 2.66개, C 인 경우 2.76개 였으며 분화도에 따라서는 고분화암인 경우 2.51개, 중등도분화암인 경우는 3.01개, 저분화암인 경우는 2.15개였다. 5년내 사망한 환자에서는 3.55개 였으며 5년이상 생존한 환자에서는 2.8개였다. 형태학적으로 apoptotic body의 수를 세어 아포토시스를 측정하여 예후예측인자로 사용할 수 있으리라 사료되며 아포토시스와 p53의 발현과의 관계를 보았을 때 특별한 상관관계를 발견 할 수 없어 bcl-2의 발현과 더불어 아토토시스와의 관게에 대하여 좀더 연구가 되어야 하겠다. Objectives : Apoptosis is a specific mode of cell death recognized by a characteristic pattern of morphological, biochemical, and molecular changes, There are several methods of detection of apoptosis. Morphological changes involve a characteristic pattern of chromation and cytoplasm. The landmark of apoptosis is endonucleolysis, with nuclear DNA initially degraded at the linker sections to fragments equivalent to single and multiple nucleosomes. Detection of DNA fragments is situ using the terminal deoxyribonucleotidyl transferase(TDT)-mediated dUTP-digoxigenin nick end labeling (TUNEL) assay is increasingly applied to investigate apoptosis. We studied the detection method of apoptosis morphologically and by using TUNEL assay and examined the correlation of p53 expression and apoptosis. Methods : Forty-five cases of colorectal cancer were selected. The number of apoptotic bodies was expressed as a number per 100 cancer cells. The TUNEL assay was performed with in situ Apoptag kit®. Results : The mean number of the apoptotic bodies was 2.28 in the patients who survived over 5 years after curative resection and 3.55 in the patients who died within 5 years(p=0.001). There was a relationship between the number of apoptotic bodies which were measured by morphologic study and the results which were measured by TUNEL assay. There was no relationship between p53 expression and apoptosis. Conclusion : These results suggest that the frequency of apoptotic bodies may be a prognostic factor for colorectal cancer and apoptosis could be measured by morphological study without special study.

IGF2 유전자는 제 11번 염색체 단완 (11p15.5)에 위치해 있으며 아버지로부터 유전된 대립형질만 기능을 하는 genomic imprinting되는 유전자이다. 이 유전자는 정상세포에서는 세포증식을 촉진시키는 작용을 하고 몇가지 암에서는 LOI에 기인한 과발현이 있는 것으로 알려져 있다. 한편 WT1 유전자는 제 11번 염색체 단완 (11p13)에 위치해 있으며 어머니로부터 유전된 대립형질만 기능을 하는 즉 IGF2 유전자와는 정반대의 genomic imprinting 되는 유전자이다. 이 유전자는 비뇨생식기관의 발생에 매우 중요한 유전자이며 암화과정에서는 암억제 유전자로서 기능한다. 소아신장에서 발생되는 Wilms 종양에서는 IGF2 유전자와 WT1 유전자의 고장이 주원인으로 생각하고 있다. 이에 근거하여 성인에서 발생되는 신장세포암에서도 Wilms 종양에서의 결과와 같을 것인지의 여부를 알기 위하여 12명의 신장세포암 환자 ( 남자 6명, 여자 6명)로부터 얻은 조직을 이용하여 이들 유전자의 발현정도를 조사하였다. 환자의 연령은 남자에서는 43세에서 56세까지였고 여자에서는 23세에서 61세까지였다. 신장세포암에서 IGF2 유전자와 WT1 유전자의 발현정도는 다같이 성별이나 연령과는 무관하였다. IGF2 유전자는 50%에서 발현되었으며, 그 발현정도는 저발현에서부터 중등도 그리고 과발현까지 다양했으며 주로 신세뇨관 부위에 있는 암세포에서 발현되었다. WT1은 56%에서 발현되었으며 과발현과 중등도 발현이 대부분이었다. IGF2 유전저의 발현과 WT1 유전자의 발현은 각 예에서 상이하게 나타나서 두 유전자간의 작용은 일치하지 않았다. IGF2 gene which was located on chromosome 11p15.5 is expressed by the paternal allele. It stimulates the cell proliferation in normal cells, however, it is over expressed in some cancers due to LOI (loss of genomic imprinting). In contrast, WT1 gene which was located on chromosome 11p13 shows maternal specific monoallelic expression. It is a very much important gene in developing urogenital system, besides, it acts as tumor suppressor gene in some cancers. IGF2 and WT1 genes are the main causative genes in Wilms tumor which is developed in pediatric kidney. To understand the status of IGF2 and WT1 expressions in renal cell carcinoma which is developed in adult life, tissues from 12 cases patients (male 6 cases ; female 6 cases) were detected by immunohistochemistry with antibodies from IGF2 and WT1 genes. To distinguish the different ages between Wilms tumor and renal cell carcinoma, the patients age in renal cell carcinoma was ranged in 43-56 years old in man and 23-61 years old in female. No direct correlation was, in general, between gene expression of IGF2 and WT1 and age or sex of patients in renal cell carcinoma. Expression of IGF2 gene revealed six of twelve (560%) and expression of WT1 gene showed seven of twelve (56%) in renal cell carcinoma, respectively. The status of IGF2 gene expression was varied from low to high expression. In contrast, the status of WT1 gene expression was higher than in IGF2 gene expression. However, there was no apparent correlation between expressions in each cases. In conclusion, IGF2 and WT1 genes are very important in carcinogenesis of renal cell carcinoma, however interaction between two genes was obscure.

Biofeedback and pelvic floor electrical stimulation are new modalities that have been advocated for the treatment of female urinary incontinence. The aim of this study was to compare prospectively the therapeutic effect of Kontinence™(HMT Co., Korea) with Compact Elite™(ECL Co., France) in female urinary incontinence. All patients were evaluated with a complete history, physical examination, urinalysis, urine culture and urodynamic study. Eighteen patients were treated with Compact Elite™, and thirteen patients with Kontinence™. Enrolled patients had completed 8 office sessions consisting of biofeedback and intravaginal electrical stimulation according to the program of each machines. Overall treatment response was graded by patients on a scale of complete cure to aggravation. At two weeks after last session, overall improvement rate was 78% in Compact Elite™group and 92% in Kontinence™group(p>0.05). Overall patients' acceptability during treatment course was greater than 80% in both machines(p>0.05). There were no unexpected clinical findings during Kontinence™ treatment. After Kontinence™treatment, there were no laboratory changes including electrocardiography, complete blood count, liver function profile, and chest PA. These results showed that the biofeedback and electrical stimulation with Kontinence™was safe and moderately effective for female urinary incontinence comparable to Compact Elite™. However, long-term results of a larger patients are needed to ensure the therapeutic effect of Kontinence™.

Background: Onychomycosis, especially toenail onychomycosis has become one of the common fungal infection and has historically been regarded as a cosmetic rather than medical problem by many patients, even by physicians. Recently, however, there are several reports that is a refractory disease which may cause a deleterious effect on patiets quality of life (QOL). Objective: The purpose of this study was to investigate the impact of toenail onychomycosis on QOL in Korea and to assess the chandes of QOL after treatment. Methods: Total 1004 patients with toenail onychomycosis which was confirmed by clinical findings and KOH preparation were were enrolled at 47 dermatologic centers in Korea, and interviewed with standardized QOL questionnaire before and after sytemic antifungal treatment. Responses to the questionnaire were scored by 5-point scale (1∼4) and averaged, and were analyzed for 5 dimensions of emotional impact, social impact, symptorn and functional impact, patients views concerning treatment, and relationship with doctor. Results: 1. Before and after treatment, the most serious impact was emotional dimension showing 1.90 and 1.30 in average score (AS), and social (AS: 1.14 and 0.83) and symptom and functional impact (AS: 1.05 and 0.92) was also affected. 2. In female rather than male, statistically more significant impact on patients QOL was observed in all dimensions. 3. After treatment, 3 of 5 dimensions were improved significantly - emotional dimension (AS : from 1.90 to 1.30), social dimension (AS: from 1.14 to 0.83), patients view concerning treatment (AS: from 1.34 to 1.02). 4. The drgree of patients satisfaction at the therapeutic effect was very high- 62.4% (immediately after treatment) and 65.8% (9 months affer initiation of treatment) of patients answered excellent or good. Conclusion: This study confirms that toenail onychomycosis has significant impact on the overall QOL of patients. Also the effect of antifungal therapy on patients QOL were watisfactory. Therefore, both doctor and patient should pay more attention to the treatment of onychomycosis. [Kor J Med Mycol 3(1): 115∼124]
