In Korea where night soil used as fertilizer for crops and vegetables they may be contaminated simultaneously with infective stage of ascaris, hookworm and other helminthes. In this circumstance, the ascaris eggs and hookworm larvae may adhere to certain kinds of leafy vegetables(Chyu, 1957) and may remain viable even after pickling in brine or in other substances (Han and Ko, 1952; Soh, 1960). It has been shown that Heliogen(Thitasut, 1961) will kill the parasite eggs and larvae, and Sodium nitrite (Kozai, 1960; Kim and Soh 1964) and Thiabendazole (Kutsmi, 1964 and 1965; Kim et al., 1966) also had ovicidal action. The present study has been planned to study the ovicidal and larvicidal actions of several chemicals in Korean pickle juice(Kimchi) and the results are summarized as follows: Heliogen solution(iodine 100 ppm) did not destroy the ascaris and hookworm eggs within 30 minutes at the temperature of 15-30 C, but the hookworm larvae were killed within 3 minutes under the same conditions. Sodium nitrite which was added to pickle juice at the rate of 0.1 percent destroyed more than 90 percent of ascaris fresh eggs within 10 days and the embryonated eggs were destroyed within 2 days. Hookworm eggs were destroyed within 3 days and larvae were killed within 7 hours. Thiabendazole which was added to pickle juice at the rate of 0.1-0.025 percent inhibited the infectivity of ascaris embryonated eggs within 24 hours and hookworm eggs were destroyed in the same concentrations of the reagent. Hydrogen ion concentration of pickle juice which was mixed with Sodium nitrite (0.1 percent) was not changed for 10 days. 1.5 mg of Sodium nitrite or Thiabendazole produced no toxicity in kidney and intestine of mice but slight pathological changes in the liver of the same animal.

We examined the incidence of anti-Ro antibodies with sera from 60 Korean patients with systemic lupus erythematosus(SLE) by double immunodiffusion. Among these 60 sera tested, 31(51.7%) showed evident immunoprecipitations against Ro antigen on the Ouchterlony plates. Several recent studies indieate that the anti-Ro antibody occurs much less frequently in Occidental lupus patients(around 30%) than in Japanese lupus patients (50%). These data may be suggestive that the racial or ethnic baekground might be an important factor determining the serological, and perhaps the clinical features of SLE.

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

PURPOSE: This study was done to examine the effects of mood state, resourcefulness, and health perception on health promoting behavior of hospital nurses. METHODS: Convenience sampling was conducted for nurses working at three University hospital and 336 nurses were selected. Data were analyzed using SPSS 18.0. RESULTS: The results of the analysis showed that the score for nurses' mood state was 41.76+/-18.90; for resourcefulness, 11.30+/-20.63; for health perception, 3.32+/-.77, and for health promoting behavior, 111.55+/-17.76. Mood state, resourcefulness, and health perception were significantly correlated with health promoting behavior. The overall explanatory power of the effects of nurses' mood state, resourcefulness, and health perception on health promoting behavior was 27.8%. CONCLUSION: Study results indicate that better mood state, higher resourcefulness, and higher health perception result in more health promoting behavior.

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.

Tumors of umbilical cord, especially angiomyxoma, are extremely rare lesions. To our knowledge, five cases of angiomyxoma have been reported previously in the umbilical cord. Sonography two weeks after the finding of an elevated serum alpha-fetoprotein, detected a mass of the umbilical cord in a 27-year-old multiparous woman at 18(+3) weeks gestation. Previous sonogram was normal (11 weeks gestational age). At 26 weeks, a premature female infant was delivered by induction and a mass was located in the region of placental insertion of the cord. Section through the mass revealed rubbery myxoid appearance. Microcopically, numerous small vascular channels with thin walls were embedded in loose myxoid matrix. A case of angiomyxoma of umbilical cord with elevation of serum alpha-fetoprotein is presented together with a review of the literature. We hope that this case will help define the natural history of primary angiomyxoma of umbilical cord.

PURPOSE: Objective measurements of knee of flexor and extensor strength using isokinetic equipment and function after total knee arthroplasty (TKA) were evaluated until postoperative 12 months. MATERIALS AND METHODS: The control group constituted of 15 persons who were of same age and weight without knee problems. Most of the patients (70%) were operated on both knees simultaneously. The patient group consisted of constituted with 20 patients (34 cases). Isokinetic testing (Cybex) of knee flexor and extensor strength of knee and functional evaluation by HSS score was performed preoperatively and at 3, 6, 12 months postoperatively. RESULTS: The peak torque of the knee extensor and flexor muscle in the patient group was decreased by 17-41% compared to the control group. Especially, the peak torque of extensor was more decreased than flexor muscles. At postoperative 12 months, the peak-torque values of hamstring and quadriceps were able to attain the same strength levels of the preoperative knee. According to the grade of the Hospital for Special Surgery knee rating scales by Insall, 28 cases (82 %) in the patient group could obtain good result at postoperative one year. CONCLUSIONS: Exercises to increase the strength of extensor should be emphasized in the rehabilitation programs after TKA
