N/A The neodymium YAG laser was used to bleeding experimental house rabbit gastric ulcer in two separate studies: (1) Extensive investigation by using the l. 06 um YAG laser wave lenth, 2 mm in spot size, 30-90 watt power and 0. 5-l. 5 sec pulse duration were performed to determine opitimal YAG laser photocoagulation parameters to maximize hemostatic efficacy while minimizing associated tissue injury. 11 out of 21 combination of power, pulse duration and spot size, with coaxial CO2 were found to be useful. (2) 11 of these treatment combination were studied more detail to assess the respective effect of pulse duration and power. Four repeated study were performed for each combination. From these studies we conclude: (1) YAG laser photocoagulation effectively stopped experimental gastric ulcer bleeding when applied at laparotomy. (2) Under the upper described condition of pulse, spot size and pulse duration most useful combinations for hemostasis were following: a) In 0. 5 sec pulse duration; 60 watt and 70 watt power. B) In 1. 0 sec pulse duration; 50-90 watt power. C) In l. 5 sec pulse duration; 40-50 watt power. (3) 3 out of 44 combination were perforated (7%) (4) Mean effective joules for hemostasis were 220. (5) There were no close relation between decrease of tissue injury, joules, power and treatment time.

Gistrfibrayic fin3inga uair direct vision were analyae in 248 patients who were diagnosi as gastric cancsr from Feb. 1980 to March 1983 in Department of Internal Medicine, Kung Nam Sacra3 Haart Hospital, Hallym Medical College, Seoul, Korea. The results were as following: 1) In 243 cases of stomicn cancer, male to femai.: ratio was 1.6 : 1. The peak ags incidence rv3s the 6th decie with 30.2, do 7th decade with 29.0% and the 5th decide with 16.1 of the patients in that order. 2) The most frsqueat site of stomach cancer was the antrum(52.8%), followed by the body (29.1%), cardia and fundus(5.2%) in order of frequency. 3) The morphologic types of 243 cases of advanced stomach cancer were 152 cases of B3rm ana typspl (61.30, 50 cases of type l( (20.2%), 38 cases of type h(l$gt;0,3%), g cases of type I (3. 2%) in order of frequency 4) In 232 biopy cases, cancsr cell were coafirme3 in 193 cass(85.9) and positive ratio of mrpholoic biopsy study was 100'/o in sormann typo I , 88. 9'/o in type ]I , 87. 9'o in type pl and 78.4% in typeIV in order of frequency. 5) Histoloic classification of gastric cancer in bispsy were g2 cases in poorly differentiated aemarinoma(4.5%), 43 C3ss3(24.9) in well dliferantiated adenocarcinoma, 33 cases(3i. 1) in signet ring call adenocarcinoma. in order of frequency. 6) Conplicatiols of gastric cncr were pyloric obstruction 45 cisas(18.1'0), cironic blood loss 40 casea(lo.l%), hemorrhage 17 cases(6.9) in order of frequency. 7) Early Gastric Cancer among 5, 209 cases was detactei in 33 cases(0. 6%). The most common type was ]Ic+JQ(42.4). 8) The dianotic positive rates of gastric cancer by UGI compared with endosopy was 8,7 (aivance:i gastric cancer: 82.3ro, early gastric cancer: 65.0%)

Cerebrospinal fluid electrolytes including Na, K and BUN were measured serially in 70 cases of various cerebrovascular accidents and were compared to those of sera in relation to the kinds of C.V.A. and progression of the diseases. The results were as follows: 1. Normal value of CSF Na was almost same to that of serum but normal value of CSF K was lower than that of serum. And the normal values of CSF K were relatively narrow in range in comparison to those of sera. 2. The change of CSF K level in subarachnoid hemorrhage cases showed a progressive decrease until 5 days after onset and then a progressive increase after about 5 days. 3. In intracerebral hemorrhage cases, the CSF K level changes were not regular and some of the cases showed a marked initial increase after onset of the disease.
