1.The Clinical Observation of the Femoral Shaft Fracture in Children
The Journal of the Korean Orthopaedic Association 1983;18(4):703-708
The management of the femoral shaft fracture in children is quite different from that of in adults. This report analysed the treatment and results in 63 children with fractures of the femoral shaft at the Chosun University Hospital during the period ranging from Jan. 1975 to Dec. 1978 and follow up study was made for 2 to 4 years following the fractures. End results obtained are as follows; 1. The sex ratio between the male and the female was 2.3: 1 and the type of fractures observed was transverse fracture(41.2%), oblique fracture (23.8%), spiral fracture (20.6%) etc. 2. The traffic accidents was most common cause of the fracture (60.3%) and the next most frequent one was fall (26.9%). 3. There was no clinical deformity at the fracture site after complete remodeling, when initial angulation was under 20 degrees. 4. The overriding of the fractured fragment in 10mm to 15mm between the age 2 to 10 years was permissible. 5. The average value of the overgrowth was 11.2mm and the growth stimulation caused no significant change under 2 years of age and over 11 years of age.

The status of DNA synthesis and the effect of UV radiation on the DNA synthesis were studied in mouse skin by microautoradiography. Mice exposed to 100mJ/cm of UVB were injected intradermally with tritiated thymidine, 5 minutes, 2, 6 and 24 hours after irradiation and biopsies were processed for light microscopic autoradiography, A total of 25 ICR female albino haired mice were used as subjects. We compared heavily labeled cells(>10 grains/nucleus) and sparsely labeled cells (3-10 grains/nucleus) in UVL irradiated skin with nonirradiated control skin. 1. Within 5 minutes after UVL exposure an apparent depression in the number of heavily labeled cells occurred. This reduction was statistically significant and remained so for at least six hours post,irradiation. By 24 hours after UVL exposure, the reduction was recovered to nearly control level. 2. By five minutes after UVL exposure, sparsely labeled cells were observed in basal cell layer and differentiated cell layer. The nurriber of sparsely labeled cells appeared highest at five minutes after UVL exposure and then tended to fall to nearly control level at 24 hours. This aberrant type of TdR H incorporation is thought to represent unscheduled DNA synthesis to repair pyrimidine dimers formed in UVL injured DNA molecules,

Our study was performed to evaluate the efficacy of anthralin-UVB therapy on patients with psoriasis. We studied twenty two patients suffering from plaque-type psoriasis of varying degrees of severity. The results can be summarized as follows. l. 2p patients(90.9%) out of the total 22 patients showed grade 4 improvement. The rernaining 2 patients failed to respond to treatment, 2. Arnong the improved 2Q patients, 2 patients who were treated more than 3p times for grade 4 improvement were excluded, so cleared patients were 18(81.8%). 3. Arnong the 18 cleared patients, the mean nurnber of therapy wasg. 6 for grade 3 and 12. 5 for grade 4 in the cases of trunk lesiona, and 13. 2 for grade 3 and 17. 8 for grade 4 in the cases of extrernities lesions. With above results, anth-ralin-UVB therapy was rnore effective in lesions of the trunk than in those of extremi.ties. 4. Notable side effects were pruritus in 6 patients(27.3pg), staining in 4 patients (18,2%), and 1ITltatioB in 2 patients(9.1%)

We performed anthralin comparative study(0.01% vs 0.1%) to assess the effectiveness of low-strengh anthralin therapy in 34 psoriatic patients and the resu1ts can be summarized as follows. 1. In the case of 13 patients using Burdick UVB larnp, in 1 patient the effect of 0.1% anthralin was superior to that of 0.01% anthralin from the start to the end of treatment, in 5 patients(38.5%) initially the effect of 0.1% anthralin was superior but in time became equal to that of 0.01% anthralin, and in 7 patients (53.8%) the effect of either side was same throughout the courae of the treatment. In the case of 21 patients using Waldmann UVB cabinet, there were 2(9.5 %), 3(14.3%) and 16 patients(76.2%) in the order named above. 2. The side effect of 0.1% anthralin was more severe than or at least the same as that of 0.01% anthralin in every patient who complained about side effects. So low-strengh anthalin-UVB phototherapy was thought to be the effective and alternative method of treatment particularly for the purpose of lessening the side effects.

Our study was performed to evaluate the efficacy of anthralin-UVB therapy for psoriasis by simplifying the conventional Ingram regimen, 34 patients(21 admitted, and 13 OPD patients) were included in our study and the resulti can be summarized as follows. 1. There were no cases of treatment failure. 16 patients(76. 2%) out of the 2l admitted patients and 7 patients(53.8%) out of the 13 OPD patients showed clearing. 2. In the case of the admitted patients, the mean numbers of therapy(days) of the improved patients reaching grade 4 were 12. 0(18. 1 days) in the trunk lesions and 15. 5 (22. 0 days) in the extremity lesions' and those of the cleared patients reaching grade 4 were 11. 2(16. 0 days) in the trunk lesions, and 13. 4(lg. 5 days) in the extremity lesions, but the difference was not significant statistically(pp o.ps). The difference between the therapeutic effects of the admitted and the OPD patients was significant statistically(p<0. 05). 3. There were some notable side effects such as staining, pruritus, and erythema, but there were no cases of therapy termination.

BACKGROUND: The wound healing process is impaired or delayed in aged patients. The development of a new wound healing model is needed. Nerve growth factor (NGF) plays a special role in wound healing because NGF is expressed only in proliferating tissues such as wounds. OBJECTIVE: The aim of our study was to develop a wound healing model using a 3-dimensional culture system, raft culture, by comparing the level of NGF expression according to the wound stage after an artificial wound was made to the raft samples. We tried to specifically localize the site of NGF expression both in mRNA and protein level. METHODS: Raft culture using normal human keratinocytes was done and a 2 mm slit wound was made in the center of the raft samples. Raft samples of no wound, 4 d, 7 d, and 9 d after wounding were prepared. In situ RT-PCR and immunohistochemistry were performed to detect and localize NGF expression after making wounds and the addition of substance P (SP). RESULTS: We failed to localize NGF mRNA expression in raft samples by in situ RT-PCR. Immunohistochemistry showed NGF staining throughout the epidermis although a little more dense staining was found in the basal layer. NGF(+) cells tended to increase until 7 d after wounding, but there were no significant differences according to the wounding days. There was `a tendency that the SP(+) group showed more NGF(+) cells than the SP(-) group, but there were no statistical differences. CONCLUSION: We think that our in vitro raft wound model using NGF expression could be used, at least in part, as an objective indicator for wound healing. In our raft model lacking nerve, NGF may not be suitable for representing wound healing process because this model can not reflect the interaction between the skin and the nervous system. Expression of growth factors or cytokines other than NGF need to be applied to our raft culture system.

Background: Triiodothyronine(T3) is a hormone secreted from thyroid gland which exerts a stimulating effect on metabolism. The disorder of thyroid system brings about several serious diseases like hypothymidism or hyperthyroidism. Therefore, the determination of T in blood is very important on monitoring thyroid function. Methods: Rabbit anti-T3 antibody was generated by immunization of T-BSA as an immunogen and purified hom antisera using Affi-gel protein A kit. The titer and specificity of purified antibody were characterized. To detect T3, competitive ELISA was performed using anti-T3 antibody and T3-HRP conjugate which was synthesized by glutaraldehyde method. The sensitivity and precision assay wer~e deterrnined and compared with that of RIA. Results: The titer of purified anti-T3 antibody was about 1:100 and the optimal dilution of T3- HRP conjugate was 1:1000. When the standard curve was constructed by ELISA, its sensitivity was about 0.5ng/ml. The eoefficient variations of intra- and inter-assay were 4.9~9.3% and 7.5~13.8%, respectively. The results obtained by ELISA and RIA correlated well with each other(n =50, r= 0.97), The linear regression equation was y= 1.09*0.08(P<0.01). Conclusion: We successfully developed a method for the measurement of T3 on ELISA which was based on competitive reaction between antigen(T3) and enzyme labeled antigen(T3-HRP). These results demonstrated that competitive ELISA is a convenient, fast, reproducible and aecurate method for the determinstion of T in serum and can be used as practical alternative to RIA.
