In the diagnosis of parasitic helminthic diseases, the value of examining and identifying the parasitic eggs and/or adult parasites from patient's urine or stool are well appreciated. However, these methods have a limited value in the diagnosis of tissue or intracellular parasitism, and we have to rely on supplementary methods such as immuno-serological test. The author tested the value of gel precipitation reactions as a diagnostic method of clonorchiasis by observing the appearance of bads on rats experimentally infected with Clonorchis sinensis. And the therapeutic effect of CIBA 35'058-Ba was evaluated by this serological method. The antigen was prepared from the adult worms infected in rabbits by Tsuji method. Rats infected with 40 metacercariae each were bled on 7, 14, 21, 26, 28, 39, 42(43), 49(53) days after infection to observe the appearance of precipitin bands by both Pucterlony method and immunoelectrophoresis. Fifteen rats were separately infected and treated with CIBA 35'058-Ba in dose of 15mg/kg of body weight. The following results were obtained : 1. It was observed that there exist individual variations in the appearance of the first precipitin band with the range of 2-4 weeks after infection. 2. The number of precipitin bands was increased until 6-7 weeks after infection. In all cases, 3 precipitin bands were appeared by Oucterlony method and 6-7 bands were appeared by immunoelectrophoresis after 6-7 weeks of infection. 3. It was hardly possible to notice any change in the number of bands after the administration of CIBA 35'058-Ba. This result suggested that the drug has no effect on clonorchiasis which was confirmed by the autopsy of the experimental rats.

Two cases of toxic epidermal necrolysis (Lyell) appearing on 69-year old male and 12year-old female were presented. The clinical manifestations of toxic epidermal necrolysis developed after oral administration of novaquing for common cold. The cause of the disease was probably due to novaquing (phenobarbital and sulpyrin). The 69 year-old male was expired despite intensive treatment with fluid and electrolytes, antibiotics, corticosteroids, vitamins, and topical measures, but 12 year-old female was cured successfully with treatment.

Since Duhamel (1739), numerous experimental studies on the longitudinal growth of growing long bone have been reported. In Hales(1747) experience, growing long bone showed overgrowth after drilling in the tibia of chickens. David(1924) observed the fact that various degrees of shortening disappeared within 15 months after fracture of the femur in children and he concluded that fractures in children should be treated with the caution that the growing long bone has a tendency to increase in length after injury. Bisgard(1936) concluded that shortening from overriding of fragments in fractured extremities of children will frequently, but not invariablly, become partially or totally eliminated by the acceleration of growth which incidentaIly results from the inflammatory process, incited by trauma and fracture repair. Hass(1926) reported that interstitial proliferation of osseous tissue plays no part in the elongation of a growing bone, either in the mature bone or the young osteoid tissue bordering on the epiphyseal cartilage plate, and length growth of bone is entirely dependant on the purposeful multiplication of cartilage cells of the epiphyseal cartilage plate. Ham(1952) reported that the growth of long bone depends upon the interstitial growth of cartilage. This study was initiated to investigate the effects of fractures in the longitudinal bone growth of growing bone. Artificial fractures were made at two different sites in the diaphysis of the tibia in young rabbits. The operation for artificial fracture was performed under general anesthesia with ether. The type of fracture was an incomplete one, leaving a part of the posterior cortex of the tibia, in order to prevent the displacement of fractured fragments. In all of the cases, no cast immobilization was applied. After the fractures, follow up observations were made weekly till the 4th week, and thereafter at two week intervals, with roentgenographic, lethal measurement and histological examination. The results were as follows; 1) Longitudinal bone growth was increased from fracture of the diaphysis of growing long bone. 2) Compared with the control limb, tendency to overgrowth of growing bone was noted from the first week after the operation. 3) In follow up measurements, no growth inhibition was observed till the 10th week after the operation, but, thereafter, a tendency to reduce the proliferation of cartilage cells was noted. 4) In cases of fracture of the mid 1/3, the gorwing activity in the epiphyseal plate was increased more than from proximal 1/3 fractures. 5) The bony growth, accelerated by fractures in diaphysis of growing long bone without displacement was transient, and the prolonged overgrowth was compensated by the reduction of growing activity and premature closure of the epiphysis.

PURPOSE: Prader-Willi Syndrome(PWS) is caused by absence of paternal contributions of the chromosome region 15q11-q13. To detact this region, high resolutional cytogenetic analysis, FISH with probe at PWS critical region or microsatellite polymorphism can be used. The gene for the small nuclear ribonucleoprotein polypeptide N(SNRPN) is not expressed in patients with PWS. We conducted molecular analysis with RT-PCR with SNRPN primers to find out more useful diagnostic tool in PWS. METHODS: Four patients with obesity and other characteristics of PWS were studied. The exprssion of SNRPN and control gene were studed by RT-PCR from peripheral lymphocytes. RESULTS :The SNRPN expression in reverse transcribed RNA from blood were easily detected in normal control but not in patients with suspected Parder-Willi Syndrome. CONCLUSION: We conclude that SNRPN expression study is a useful diagnostic method for detection of Prader-Willi Syndrome.

Letterer-Siwe disease is a non-lipid reticuloendotheliosis of unknown etiology and usually grouped with Hand-Schuller-Christian disease and eosinophilic granuloma as components of histiocytosis-X. It occurs mostly in infancy and, clinically it is the most generalliaed and serious. In recent years, the prognosis of infants with Letterer-Siwe disease has improved, primarily due to more aggressive therapy with corticosteroids and antimetabolic agents. The 14 months old male patient was admitted into the Severance Hospital on 15th, July 1974 for evaluation of a chronic and refractory skin eruptions, abdominal distension with diarrhea and edema on extremities. He had been well until 3 months old age when he developed seborrhea-like skin eruptions which did not improve on treatment for seborrhea. Vigorous treatment was started for the baby from the beginning of admission day. Routine laboratory tests, skin biopsy, bone marrow aspiration and radiologic studies for bony structures wer done. All those studies had showed severe anemia, thrombocytopenia, multiple bony defects in skull and numerous non-lipid histiocytic infiltration in skin and bone marrow all those were consist with Letterer-Siwe disease.

BACKGROUND: Hair casts(HGs) is a disorder of asymptomatic, firm yellowish white, freely movable accretions which encircles but is not attatched to the hairs. There are two types of HC:The first type, parakeratotic HC, is frequently associated with parakeratotic scalp disorders;the second type, the peripilar keratin casts, in an uncommon type not usually associated with diseases of the scalp and has only been reported in female children. The pathophysiology and origin of HC is poorly understood with only 37 cases reported in the literature. @ ES OBJECTIVE: our pupose was to establish the prevalence of hair cast in schoold children and to determine the predisposing factors of hair casts in Korea. METHODS: Five hundred and thirty-seven students of elementary schools(274male, 263female) were examined. Samples of plucked hair were stained with 4-dimethylaminocinnamaldehyde and examined under light microscopes. RESULTS: There were 182 patients with HC;Peripilar keratin casts:174(CRSC 165, ERSC 7, IRSC 2); paakeratotic HC:8. In a total of 182 patients with HC, 181 were girls and the incidence of HC in female children was 68.8%(181/263). In girls who tie up or weave their hair, the incidence of peripilar keratin casts was as high as 81.8%(171/209). CONCLUSIONS: These data suggest that the traction to the hair follicle may play a role in the generation of HC, and that peripilar keratin casts are not rare in Korea.

OBJECTIVE: Mycoplasma pneumoniae infection is known as one of the frequent causes of exacerbation of bronchial asthma and it can also be a trigger for the initiation of asthma. However, little is known about the pathogenesis of respiratory M. pneumoniae infection. Furthermore, there is little data on human cytokine production and its involvement in the pathogenesis of M. pneumoniae infection. In order to investigate the immunopathogenesis of M. pneumoniae infection, we investigated the cytokine production in the bronchoalveolar lavage ( BAL ) fluid of patients with M. pneumoniae pneumonia and viral pneumonia, and compared the results with those of control subjects. SUBJECT AND METHOD: BAL was performed with fiberoptic bronchoscopy in patients with M. pneumoniae pneumonia( n=9 ), viral pneumonia( n=9 ), and control subjects( n=6 ) aged 3 years to 9 years. M. pneumoniae pneumonia was documented by polymerase chain reaction and serologic analysis. Four respiratory viruses ( adenovirus, influenza A, influenza B, parainfluenza ) were detected by culture method. Cell pellets and supernatants were separated by centrifugation and Interleukin( IL ) - 2, Interferon( IFN )-r, IL-4, and IL-5 levels were measured in concentrated BAL supernatants by ELISA. RESULTS: Analysis of cytokines revealed significantly increased production of IL-4 ( p< 0.0001 ) and IL-2 ( p< 0.0001 ), in patients with M. pneumoniae pneumonia and significantly increased production of IL-2 (p <0.0001) in patients with viral pneumonia compared with those of the control subjects. Ratio of IL-4/IFN-r was significantly increased in patients with M. pneumoniae pneumonia ( p< 0.005 ) but not in patients with viral pneumonia compared with that of the control subjects. CONCLUSION: IL-4 production and IL-4/IFN-r ratio were increased in the BAL fluid of patients with M. pneumoniae infection. These findings suggest that predominant Th2 immune response could play an important role in the pathogenesis of M. pneumoniae infection.
