As the incidence of dermographism in our urticaria clinie is quite high comparing data in other country, we have tried to survey the incidence of ermographism in the general population of Korea using a dermographic tester designed by other author. Total 8g7 healthy persons were included in this study from March J98$ to .December 1983. The study result was summarized as follows, 1. Male to female ratio was 2. 5: 1 and the peak age of the subjects was third(47 8%), fourth and fith decades in ecreasing order, The overall incidence of dermographisrn from the pressure of 48ppg/cm was 4.4% and there were no significa.nt difference in the incidences between male(4, 2%) and female(4 7%) (p>0. 1), and between the different age groups(p>0 l)

In situ hybridization (ISH) is a standard method for localizing DNA or RNA sequences in tissue or cell preperation. The technique was developed at the electron-microscopic level, and enables the precise subcellular localization. A method was developed for detection of specific viral DNA. We have tested various methods and technique to detect specific viral DNA through ISH at the electron microscopic level. Postembedding method of ultrastructural ISH was developed and successfully applied for the detection of human papillomavirus type 16 in squamous cell carcinoma of the uterine cervix and Epstein-Barr virus in EBV-infected leukemia cell line. The following results are made. The best results were obtained using 0.2% glutaraldehyde and 4% paraformaldehyde fixed tissue or cell block. The labelling was best observed on Unicryl resin and Lowicryl K4M resin sections. Epon sections showed no reactivity. Thin sections of Unicryl resin were more easier than Lowicryl K4M resin. Enzymatic predigestion with proteinase K, pepsin and trypsind gave good results. However, high concentration of these produce poor results due to excessive destruction of the cellular components. Alkali treatment with 0.5N sodium hydroxide produced successful results in denaturation of target DNA. The labelling density of gold particles was independent of incubation time or temperature in hybridization step. The viral DNA labelling was localized mainly within the nucleus, both within and at the edge of electron dense regions, and below the nuclear membrane. And the labelling was seen in the form of a dense, roughly spherical shape. In conclusion, the best results are obtained by the conditions that tissue fixed by 0.2% glutaraldehyde and 4% paraformaldehyde solution, embedded with Unicryl resin, protein denaturation by 0.1ul/ml proteinase K, DNA denaturation by 0.5N sodium hydroxide, and reaction with DNA probe.

To evaluate the efficacy of STIR (short tau inversio recovery) image in the diagnosis of orbital diseases, we compared the STIR images with conventional SE(spin-echo) images in 17 patients. The fat signal was reliably nulled at inversion time of approximately 160-170 msec in all cases. We analyzed all the cases in the aspects of the detection of lesion and the lesion-to-back ground contrast retrospectively. Regarding lesion, the detection rates of STIR, T1 and T2-weighted images were 89, 88 and 83% respectively. In the aspect of lesion-to-background contrast, the contrast ratios of STIR and T1, T2-weighted image were 87% and 64, 56%, respectively. In conclusion, STIR images were similar to T1-and T2-weighted images in the detection of lesion, but superior in the aspect of lesion-to-background contrast. So the STIR images may be a useful adjunct to conventional SE images for the diagnosis of orbital disease.

Vasoconstrictive effect of several topicsl corticosteroids was measured using laser Doppler flowmeter. Hydrophilic ointment base, 1% hydrocortisone cream, 0.1% clocortolone pivalate cream, and 0.25% desoxymethasone cream were applied on both forearms of 20 volunteers. To augment the vasoconstrictive effect of the corticosteroids, We had cut off the blood flow to forearms for 4 minutes by tourniquet. The reactive hyperemia was measured by laser Doppler flowmeter and the ares under the curve were calculated by digitizer aided by a computer. The mean areas of esch drugs were in the following order : hydrophilic ointment base, 0.1% clocortolone pivalate cream, 1% hydrocortisone crearn and 0.25% desoxymethasone cream. However, the standard deviations were too large for the difference to be statistically significant. We concluded that laser Doppler flowmeter is not suitable for the measurement of vasoconstrictive effect of corticosteroid.
