Intussusception is the invagination of one portion of the intestine into the contiguous distal segment. During infancy and childhood it is the most common cause of acquired intestinal obstruction. This is a clinical and radiological study of 120 cases who visited our

The pancreas is the only organ in the body which reacts to trauma or inflammation by autolysis and the for. mation of a pseudocyst. Pancreatic pseudocysts are thought to develop secondary to rupture of a pancreatic duct with escape of pancreatic juìce into the surrounding tissue or spaces. The fluid becomes loculated and a fibrous wall results from the secondary inflammation. There is no epithelial cell lining the cystic wal l. The results were summarized as foliows;1. The ratio of male and fe male was 1. 7:1 , ar,J the ages of most of patients ranged from 21 to 50 years.2. Of our 16 cases, 7 cases had a history of pancreatitis, 5 cases trauma but no specific past hi story was obtained in 2 cases.3. Most frequent outstanding clinical symptoms and sig ns we re abdominal pain(87.5%) , tenderness(8 1. 3%) and palpable mass(68.8% ).4. In laboratory findings , serum amylase level was elevated in 9 cases, leukocytosis in 5 cases and significant snemia on admission in 6 cases.5. Radiographic ex amination , especialiy UGI seri es was most useful diagnostic aid. The most common and important radiologic finding was anterior displ aceme nt of stomach and extrinsic compression(87.5 %).6. The location of pseudocyst was in body(62.5 %). tail(25.0%) and head (12.5%) of the pancreas in order.

The X-ray Mucous Membrane Funct ion T es t (X. M. F. T. ) is a method of evaluating the functional capac it y of the ci li ated epi t helium of t he mUCG lI S me rr'l brane of the sinus and grade of patho lo gical changes in the tunica propria by demonstrating the images cast by the contrast material (2.5 cc of 20% moljodo l) injected into the maxillary sinus. This method is essentiall y different fro m the conventional simple X-ray studies, because it is able to observe presence and chracter of the contents within the sinus cavity and also to visualize the sinus orifice and extrasinus structuresThe authors performed a modified X -ray Mucous Membrane Function Test (central ray was directed 15' cauded in erect lateral view) to the patient in whom chronic maxill ary sinusitis was suspected clinically during the period of 7 months from February 1975 to August 1975The results obtained were as follows:1. A total number of the patient received X. M. F. T. was 90 and sex distribution was 54 (60%) males and 36 (40%) females. Most of the patient (82.2% ) was distributed in 11-40 years of age and peak incidence (40% ) was in 11 -20 years of age.2. Among a total of 90 patient, bilatera l X. M. F. T. was performed in 75 patient and unilateral in 15 patient. In a sum of 165 maxillary s inuses, 79 cases (47.88 %) were on the right side and 86 cases (52. 12 %) were on the lef t side.3. Takahashi' s classification of moljodol X-ray images, i. e. A) complete diffusely spread type, B) incomplete diffusely spread type, C) spotted type, D) diffuse loca lized transitional type, E) localized type , F) scattered type were observed in our cases. But we recognized G) non fi !l ing type, which T akahashi did not m ention. It was due to seve r e chronic maxillary sinusitis, extensive
