Since the pattern of the frequency distribution of a parasite within a host showed an overdispersed pattern, various statistical models such as Poisson, negative binomial and lognormal distributions have been applied on the population dynamics in host-parasite relations. The observed data on the number of metacercariae of Clonorchis sinensis in a suitable intermediate host, Pseudorasbora parva which were collected from an endemic area, Juk-Rim River, Kim-Hae Goon, South Kyong-Sang Do were applied on the statistical models. The results obtained are as follows: By the calculation of the raw data, 258(94.9 percent) out of 272 fish showed positive to the metacercarial infection of C. sinensis. The mean number of metacercaria in a fish was 335.1. The standard deviation was 250.6 and the mode was observed between 250 and 299. The frequency distribution pattern of metacercariae of C. sinensis within the fish host in surveyed area was fitted to the lognormal distribution (0.05 parasitology-helminth-trematoda ; Clonorchis sinensis ; metacercaria ; Pseudorasbora parva ; frequency distribution ; host

Since the introduction of MRI, the arachnoiditis could easily haute been diagnosed by confirming the abnormal distribution of the roots in the dural sac. But the arachnoiditis-like pattern of nerve root distribution in a degenerative disc disease has been regarded as a an incorrect diagnosis of arachnoiditis. The arachnoiditis has been one of the most serious complication in the failed back surgery syndrome. MR images of 32 patients with acute or chronic radicular pain syndrome were investigated by a radiologist and a orthopedc surgeon. 17 patients had lumbar disc herniation; 13 patients, pure spinal stenosis; 2 patients, spondylolisthesis. The discriminant analysis was used to calculate the cutting point of clumping for the abnormal nerve root distribution and to assess the relationship between the arachnoiditis-like pattern of nerve root distribution and other factors According to the result of calculation, the cutting point of clumping In spinal stenosis was 9mm and that in a disc herniation was 6mm. Central clumping of nerve roots in the durn is considered as a characteristic finding at the constricted level of the lumbar degenerative disease. However, the appearance is not a differentiating factor between the adhesive arachnoiditis and constriction in the lumbar degenerative disease. Clinically, the adhesive arachnoiditis should be suspected in the lumbar degenerative disease with the nerve root clumping at multiple level, not associated with remarkable constriction of spinal canal. In the disc herniation with their sagittal diameter over 6mm, the clumping seems to imply the possibility of association with adhesive arachnoiditis.

Analyses were done on one hudred and twenty caaes of bleeding gastric ulcers diagnosed by emergency endoscopy for the past five years. The reaults are as the following: Much more cases were found in male than female and the most prevalent age group was 6th decade. The body of stomach along the lesser curvature was the most common bleeding site. No age related difference was noted in bleeding sites. Most common type of ulcer was in the round and shallow form. Five of six cases with exposed vessels showed atrophic changes in surrounding mucosa. Among the probable precipitating factors, analgesica, alcohols and certicosteroids were found in such order,

Obstruction on the urinary tract eventually results in damage to the kidneys and loss of function. The questions that concern the clinician are the degree of nephron loss in that kidney and the potential for recovery following the relief of obstruction. 99mTc DMSA accumulates in tubule cells and has been proposed as a marker of the tubular mass. The authors estimated the renal uptake ratio of 99mTc DMSA for the degree of nephron loss corresponding to duration of hydronephrosis following left ureteral ligation in 5 NewZealand white rabbits and the potential for recovery following percutaneous nephrostomy of hydronephrosis in 24 rabbits. While the renal uptake ratio of 99mTc DMSA of the kidney with unilateral hydronephrosis following ureteral ligation reduced dramatically within 24 hour, that of the opposite healthy kidney increased, and the total renal uptake ratio was same as normal functioning kidneys before ureteral ligation. Upon ureteral release, there was no evidence of definite recovery or impairment in the experimental kidneys for 5 days. The authors conclude that a combination of ureteral release and administration of some drugs such as renal vasodilator or diuretics is an appropriate treatment for the recovery of function in unilateral hydronephrosis.

Statistical analysis according to W.H.O. classification for the patients admitted the Ped. Dept. of Han-Il Hospital was carried out during 4 years from Jan. 1974 to Dec. 1977. The following results were observed. 1. Total No. of patient during 4 years period were 1955, of which 1199 were male(61.33%, 756 were female(38.67%) and male to femal ratio was 1.57:1. 2. There was no significant variation. 3. According to age, preschool aged group as the most frequent group consistin of 488 cases(24.49%), school aged group and adolescent in the order of frequency. 4. On monthly distribution, there was no significant variation 5. Most frequent diseases in pediatric age group were respiratory tract one, 851 cases(39.29%) : infectious and parasitic ones, 553(25.53%) and neonatal disease, 204 cases(9.42%) in the order of frequency. 6. Among respiratory tract disease, pneumonia was the most frequent one, 587 cases(27.10%). 7. Among infectious and parasitic disease group, gastrointestinal infectious one was the most frequent, 224 cases(10.34%) : other viral disease and tuberculosis in the order of frequency. 8. Among neonatal diseases, prematurity was the most frequent one, 82 cases(3.79%).

PURPOSE: Electrogastrography is a method of measuring action potentials of the stomach. The purpose of this study was to investigate early postoperative changes in the electrogastrography and determine the correlation between electrogastrography and quality of life of patients with stomach cancer who underwent distal gastrectomy. MATERIALS AND METHODS: This study analyzed 20 patients with stomach cancer who underwent electrogastrography and quality of life was measured 1, 12, and 24 weeks after the operation. Quality of life-C30 version 3.0 and quality of life-STO22, were used. RESULTS: Fasting and postprandial mean dominant frequency at 1 week after the operation was 2.7 and 2.7 cycles per minute, and 2.8 and 2.7 cycles per minute at 12 weeks, 2.6 and 2.8 cycles per minute at 24 weeks. Fasting and postprandial mean dominant power at 1 week was 36.5 and 36.4 dB, 36.3 and 40.1 dB at 12 weeks and 40.9 and 42.3 dB at 24 weeks. The percentage of tachygastria was increased whereas the percentage of bradygradia was decreased during the postoperative periods (P<0.05). Global health, physical, emotional and social functioning scales were improved, but role and cognitive functioning were not changed. Pain, insomnia, diarrhea and financial difficulties were significantly improved according to the postoperative periods (P<0.05). The correlation between the STO22 and electrogastrography parameters was not significant (P>0.05). CONCLUSIONS: These may suggest that electrogastrography is a simple and noninvasive method and may be applicated for evaluating motility and autonomic functions of the remnant stomach.
