Human stem cells have been isolated from embryos as well as diverse somatic tissues. Much efforts have been made to apply those stem cells for therapeutic purpose. Molecular dissection of "stemness" and differentiation process will provide us a clue to further understanding of stem cell biology. The fate of stem cell is determined in part by internal regulation mediated by transcriptional control. A set of genes related to specific functions might be expressed and suppressed upon external or internal signaling. Therefore, it is necessary to identify the complete gene expression profile that defines the stem cell. Moreover, we should verify the potential of therapeutic stem cells regarding differentiation, specific function, tumorigenecity, and toxicity rigorously before the clinical application. At present we have only limited information on "stemness" and differentiation into specific lineages. In the genome era, we can draw a molecular portrait on these functional and morphologic changes along the differentiation, trans-differentiation as well as de-differentiation using the DNA chip technology. We need to accumulate database for gene expression at various steps of stem cell differentiation, which will enhance our knowledge for research on and medical application of stem cell.

OBJECTIVE: This study was performed to evaluate the clinical efficacy of high-risk HPV DNA test using Hybrid Capture System in the detection of high-grade cervical intraepithelial neo- plasia(CIN II, III) from patients with atypical squamous cells of undetermined significance(ASCUS) or a low-grade squamous intraepithelial lesion(LGSIL) on referral Papanicolaou smear. STUDY DESIGN: Fifty-four patients referred to our hospital with a Papanicolaou smear report of atypical squamous cells of undetermined significance or a low-grade squamous intraepithelial lesion underwent repeat Papanicolaou smear, cervical colposcopy and directed cervical biopsy. In addition, high-risk human papillomavirus(HPV) test by Hybrid Capture System was done. A comparison of detection rate of the high-grade CIN between positive and negative results of HPV test according to repeat Papanicolaou smear report was done. Biopsy result according to HPV test result in total patients was also compared. RESULTS: HPV of high-risk type was detected in 22 of 54 women(40.7%) by Hybrid Capture System. Prevalence rate of high-risk HPV in no CIN, CIN I, and CIN II, III was 13.6%, 18.2% and 68.2% respectively. As expected, high-risk HPV was detected with greater frequency in relation to increasing severity of CIN. In 18 women, the repeat smear obtained in our clinic was reported as negative. High-risk HPV types were found in 16.7% of theses women. In the HPV-negative women, 40% had CIN II or III confirmed on cervical biopsy. In comparison, 66.7% of those with a positive result of the HPV test had CIN II or III on biopsy(P<0.05). Among the women with ASCUS or LGSIL on repeat smear, there was no significant difference in the frequency of biopsy-proved CIN II or III between positive and negative results of high-risk HPV test. In total patients, the group that had positive results for high-risk HPV showed higher incidence of CIN II or III than group with negative results(P<0.05). CONCLUSION: From these results testing women with Papanicolaou smears showing ASCUS or LGSIL for infection with high-risk HPV types would identify the patients who are at risk for HGSIL or invasive carcinoma and who require aggressive intervention. High-risk HPV DNA test using Hybrid Capture System may be a usefule method in supplement the pitfalls of cervical cytology. This test might also have prgnostic value in the management of patients with cervical intraepithelial lesions.

This study was undertaken to investigate to compare the ratio of positive reactions to benzoic acid(BA), sorbic acid(SA) and cinnamic acid(CA) which are well known materials producing non-immunologic contact urticaria. Various concentrations(0.l% to 5%) and different vehicles(petrolatum, water, hydrophilic ointment base) were used in open and 20 minutes closed test using Finn chamber on Scanpor tape. One hundred total subjects were consisted of nonallergic patients and normal persons. The results were as follows ; 1. Total numbers of positive reactions were 69 in closed test(CT) and 60 in open test(OT), regardless of the materials and vehicles. 2. Total riumbers of positive reactions in BA, SA and CA were 68, 31, 35 in CT and 59, 20, 14 in OT respectably. 3. CT showed much more positive reactions than OT with all materials tested except 0.l% SA in water. 4. Hydrophilic ointment base showed a better reactivity than any other vehicles in CT. But in OT, petrolatum, water, hydrophilic ointment base showed better reactivity in BA, SA, CA respectably. 5. Almost all the reactions appeared within 45 minutes and disappeared within 3 hours. Erythema preceded edema and persisted 30 minutes to 1 hour after dissappearance of edema. 6 Itching, burning and tingling sensation were the only symptoms observed except. localized erythema and edema.

Forehead deep wrinkles make man's face ugly. Especially, in case that a young people has short forehead, one or two forehead deep wrinkles is likely go give a aggressive impression to people. Traditional forehead lift basically not only perfrom the selective excision of frontalis muscle which cause forehead wrinkles, but extend the width of forehead by practical lift through scalp excision. Recently, various filling materials such as collagen have been developing, and laser resurfacing and endoscopic plastic surgery has gradually been generalized, so the frequency of the traditional forehead lift which needs the extensive operation through coronal incision is gradually diminished. But collagen injection is repeatedly taken every regular times and it has a weak point that the width of forehead cannot be regulated. Laser resurfacing can't solve the problem of deep wrinkles. The purpose of endoscopic brow lift which has been generalized currently is mainly brow lift, and so this method is not good for deep wrinkles because it can't modualte frontalis muscle which cause forehead transverse wrinkles. Recently it has been reported that Alloderm composed of dermal collagen from cadavar skin is universally used in covering as well as filling up soft tissue defect and its usability is also successful. Authors recently correct three young persons who have forehead deep wrinkles by combination of endoscopic forehead lift and subcutaneous Alloderm implantation under the wrinkles for 2 years. At first, we extended the width of forehead and smoothed the depth of wrinkles by endoscopic brow lift. After having endoscopic operation, we inserted Alloderm in subcutaneous pocket and performed suspension suture outside. The average increase of forehead width is 5 mm and all patients had corrected transverse wrinkles remarkably. During the 9 months, wrinkles didn't recur and implanted Alloderm also didn't absorbed. As a better method, authors reported that combining endoscopic brow lift with Alloderm implantation for the correction of short forehead and deep wrinkles could be used in place of traditional forehead lift.
