It is now well-known that the electronic data processing system(EDPS: computer) is very useful for indexing, sorting, verification, and so on. And a few orthopedics in Korea are processing informations with computers for their medical records respeetively. But since there are no established principles on the description of orthopedic diseases, a computer programmer unfamiliar with medical terms is poor in electronic processing for medical records. After processing with an IBM computer for several years, it has come to our attention that we have a need for standardization of the description of orthopedic diseases for EDPS. Based largely on the International Classification of Diseases(ICD-9th), we propose the following: 1. Diseases should be written in English, and whether it be capital letter or small letter does not matter. 2. Description of the disease should be in order of title, region of the body, cause or present status, and side of the body. The sequence may be changed without problem, but only the noun form should be used. It is also recommended that the key words in articles be defined. 3. Abbreviated forms should be avoided. If inevitable, the abbreviation should be used consistently from the first to the 1ast. 4. Connection with other types of medical records such as medical insurance system by registering the code number of the International Classification of Disesaes at the end of the description or on another line.

When ultrasound or computed tomographic (CT) scans demonstrate a focal mass within the pancreas, the radiologist or gastroenterologist assumes that it is carcinoma. Statistically this is the correct diagnosis. However, distinguishing pancreatitis from carcinoma by ultrasound and CT is occassionally impossible. Similarly, abnormalities seen on ERCP, such as simultaneous obstruction of both the common bile duct and adjacent pancreatic duct (double duct sign), has been shown to occur in pancreatitis as well as in the more commonly diagnosed pancreatic carcinoma. We experienced 3 cases af focal pancreatic masses that mistaken a carcinoma. And so, knowledge that such a mass can be benign in a clinical setting sbould result in an organiged approach to the correct diagnosis and avoidance of any unnecessary operations.

The T cell responses to hepatitis B surface antigen (HBsAg) were analyzed in acute hepatitis patients, chronic active hepatitis (CAH) patients and asymptomatic carriers. Neither proliferative responses nor substantial cytokine production of peripheral blood mononuclear cells (PBMC) in response to HBsAg was detected. For further studies, HBsAg- reactive T cell lines were prepared from PBMC of the hepatitis patients and asymptomatic carriers. No proliferative response of the T cell lines was observed. Interestingly, however, T cell lines obtained from acute hepatitis patients were found to produce IFN-r, but not IL- 4, in response to HBsAg stimulation, whereas T cell lines obtained from CAH patients and carriers were not. Results of this study suggest that HBsAg-reactive T cells producing Thl type cytokines may play an important role in the viral clearance during acute infections, while defects in those T cells may be responsible for the viral persistency.

Several observation suggest that the antimelanocyte autoantibodies could play a role in melanocyte destruction. Some experiments indicate that melanocyte antibodies from patients with vitiligo can kill melanocyte in vitro. In these experiments, we demonstrated that vitiligo patient's sera containing antimelanocyte antibodies can lyse cultured human melanocytes by complement activation. Melanocyte cytotoxicity was measured using the ethidium bromide/ acridine orange viability assay. Significant melanocyte cytotoxicity was seen in sera from patients with both active and inactive vitiligo(p<0.01). Melanocyte cytotoxicity measured with complement-mediated cytotoxicity decreased after systemic steroid treatment(p<0.05) ; however melanocyte cytotoxicity showed no significant change with systemic PUVA therapy.

In 228 sera from untreated syphilitic patients with different clinical stages and 52 healthy persons, the presence of treponema-specific 19S(IgM) antibodies were demonstrated by using the l9S(IgM)-FTA test. Of 228 sera, 160 were syphilitic sera based on symptoms, clinical history and serologic tests (VDRL, FTA-ABS and TPHA). The sensitivity of the 19S(IgM)-FTA test was 98g in 160 syphilitic sera, especially lp0, in primary syphilis. Remaining 68 positive sera(30) in VDRL, FTA-ABS or TPHA showed nonreactive in ]9S(lgM)-FTA test, which seemed to be spontaneously healed sera. The specificity of the l9S(IgM)--FTA test was 98% in 52 healthy sera.

We experienced a case of congenital goiter with congenital hypothyroidism in 45 day-old male, who complained of respiratory difficulty and anterior neck mass. After admission, he was diagnosed congenital hypothyroidism by the clinical manifestations and laboratory tests including biochemistry, radioimmunoassay, radioisotope study, perchlorate discharge test, and bone radiography. We obtained positive finding at the perchlorate discharge test and found that his congenital goiter with congenital hypothyroidism was manifested by organification defect. We started treatment with L-thyroxine orally at 6th hospital day. The case was presented with brief review of literatures.

Respiratory distress syndrome (RDS) of preterm infants remains a significant cause of morbidity and mortality despite improvements in neonatal intensive care and artificial ventilatory techniques. After identification of the deficiency of pulmonary surfactant is major pathophysiologic basis in RDS, artificial surfactant replacement therapy in RDS was first successfully tested by Fujiwara and co-workers in 1980. therefore, exogenous surfactant replacement produced exellent results in improved clinical and repiratory status during the acute period and decreased incidence of late complications and mortality. According to comparison of administration timing between early (within 6 hours after birth) and late (after 6 hours)group, early replacement therapy is more effective in improving of clinical course and prognosis. Because of that, early, just after birth, recognition and detection of RDS is also important procedure. There are many investigations and methods for the detection of RDS in prenatal or postnatal period. Among then, stable microbubble rating (SMR) test was a simple method and SMR test has a higher diagnostic accuracy. To determine the relation of the SMR and purified natural surfactant (PNS) concentration in vitro, the author conducted each 5 times test of SMR method according to 5 groups of PNS concentration by using modified Pattle's method. The results were as follows: 1) The mean and standard deviation of SMR according to 5 groups of PNS concentration were 119.4 (15.0in 20mug PL (phospholipid)/ml, 452.2 (160.2 in 40mug PL/ml, 879.0 (93.4 in 60mug PL/ml, 1311.8 (274.8in80mug PL/ml, 1710.6(272.3 in 100mug PL/ml. 2) The regression curve of SMR and PNS concentration showed statistically significant relation(p<0.005). In conclusion, the SMR test was a good method in estimation of surfactant concentration in vitro and also in diagnosis of RDS recognized as a surfactant deficiency. In the future, we expected that prophylactic surfactant replacement therapy. immediate after birth, will be more popular in the field of neonatal care of RDS. So, we recommended the use of this method for early detection and serving optimal care of RDS.

PURPOSE: To demonstrate the characterization calretinin-immunoreactive displaced amacrine cells in the ganglion cell layer using immunohistochemistry and electron microscopy. METHODS: For immunohistochemistry, sections from guinea pig retina were incubated with mouse monoclonal antibody directed against calretinin. For double label studies, sections were incuated in mixture of mouse monoclonal anti-calretinin or rabbit polyclonal anti-calretinin with following antibodies: goat polyclonal anti-ChAT, rabbit polyclonal anti-GABA, mouse monoclonal anti-GABAA receptor alpha1, beta2/3. Sections were analyzed using Bio-rad Radiance Plus confocal scanning microscope. Stained sections from three guinea pig were observed with transmission electron microscope. RESULTS: Calretinin immunoreactivity was present in displaced amacrine cells and ganglion cells gaving rise to processes ramified in the inner part of the inner plexiform layer in stratum 4. The same stratum was also occupied by the dendrites of ON-cholinergic amacrine cells. Double-labeling demonstrated that dendrites and cell bodies of displaced amacrine cells colocalized with ON-cholinergic amacrine cells and dendrites of ganglion cells directly overlapped with dendrites of ON-cholinergic amacrine cells. The synaptic connectivity was identified by electron microscopy. Ganglion cell dendrites received synaptic input from ON-cholinergic amacrine cell. GABAA receptor beta2/3 subunit bands cofaciculates the dendrites of displaced amacrine cell and ganglion cell that are juxtapose to the alpha1 subunit of GABAA receptor. CONCLUSIONS: These results indicate that ON-cholinergic amacrine cells modulate calretinin-labeled ganglion cell via GABAA receptor beta2/3 in the guinea pig retina.
