N/A Objectives : We performed following experiment in order to find the relationship between impairment of pulmonary function test (PFT) and oxygen desaturation during upper gastrointestinal endoscopy examination among the elderly patients. Methods : Pulmonary function test and ABGA (arterial blood gas analysis) were performed before endoscopy. Arterial oxygen saturation and pulse rate were monitored with pulse oximeter before endoscopy until 5minutes its completion. We classified the population by control group and patients group by pulmonary function test. we classified patients group by mild group, moderate group and severe group (Table 2). Results : 1) Oxygen saturation was decreased significantly among all of groups, the most decreased within 1 minutes after insertion endoscopy and recovered soon before endoscopic completion. 2) The duration of worst SaO2 did not correlated with the pulmonary function test impairment. 3) The time of endoscopy did not correlated with decrease in SaO2 during endoscopy 4) There is decreased oxygen saturation in mild group, but no significant change from control group. 6) Pulse rate did not correlated with pulonary function test impairment. Conclualon : Oxygen saturation was decreased all groups in elderly populaton during upper gastro-intestinal endoscopy especially moderate or severe groups, therefore, incidence of cardio-pulmonary disease is increased. To prevent cardio-pulmonary complication, we should detect oxygen desaturation early by using pulse oximeter during upper gastrointestinal endoscopic procedure in moderate or severe group. If needed, termination of the procedure, oxygen supplement or assisted ventilation minimize cardiopulmonary complication.

Annular pustular psoriasis(APP) is a rare variant of the generalized pustular psoriasis characterized by subacute onset of annular lesion with peripheral advancing pustules. Histologically, it is characterized by spongiform and/or subcomeal pustules which are also found in subcomeal pustular dermatosis(SPO). SPD is very difficult to differentiate from APP, although SPO is thought to be a separate and distinctive entity because of its clinical appearance, characteristic histology, and response to dapsone. We herein report a case of APP showing clinical nod histologic features of SPO developed in a patient who had a history of generalized pustular psoriasis. (Korean J Dermatol 2002;40(12) : 1527∼1530)

In recent years, gonorrhea has been pandemic and remains one of the most common STDs in the world, especially in developing countries. For the detection of a more effective therapeutic regimen and assessing the prevalence of Penicillinase Producing Neisseria gonorrhoeae(PPNG), we have been trying to study the patients who have visited the Venereal Disease Clinic of Choong-Ku Public Health Center in Seoul since 1980 by menas of the chromogenic cephalosporin method. In 1998, 93 strians of N. genorrhoeae were isolated, among which 60(64.5%) were PPNG. The prevalence of PPNG in Seoul, which had been decreased to 39% in 1996 after a peak of 74.3% in 1993, is increased to 64.5% in 1998.

This study was carried out to demonstrate the superiority of used packing in view of energy saving and efficiency of mass transfer, comparing with conventional packing. The results are as follows 1. Owing to low pressure drop under high load, 25mm NSW-ring, pp. can cause energy saving. 2. The unique magnitudes of used packing are as follows : C_(G) = 5.78 m = 0.67 n = 0.46 3. Used packing can make high efficiency including energy saving because of low pressure drop per the number of transfer unit. To rate the characteristic of packing, it should be carried out that the measurement of pressure drop per packing height and per the number of transfer unit. This study demonstrated the superiority of used packing by caning out above experiment and could be used as basic reference for design and predicting efficiency of packing tower which is filled with same packing.
