PURPOSE: The relationship between altered HLA expressions and cervical carcinogenesis is not fully elucidated. MATERIALS AND METHODS: The histological evaluation comprised of 21 microinvasive squamous cell carcinoma (SCC), 26 invasive SCC, 3 microinvasive adenocarcinoma and 9 invasive adeno carcinoma of cervix. We used monoclonal antibodys (mAbs) to HLA class I beta2-microglobulin (L368), HLA class I B/C heavy chains (HC-10) and HLA class II heavy chain (LG II-612.14). RESULTS: In tissues from microinvasive SCC, the expressions of B/C heavy chains and class II heavy chain were significantly decreased. The expressions of beta2-microglobulin, B/C chains, and class II heavy chain in SCC were all significantly decreased. Especially, in the metastatic tissue from the same patient, the expressions of beta2-microglobulin and B/C chains showed to be somewhat decreased compared to those in primary tumor tissues, and the expression of class II heavy chain was decreased further than that in primary lesion. In primary invasive adenocarcinoma, the expression of B/C chains was significantly decreased. CONCLUSION: These results suggest that alterations of HLA class I and II expressions seem to occur at a particular step in tumor development and depend on tissue types: when the tumor becomes invasive and starts to metastasize.

Regulation of respiration differs significantly between wakefulness and sleep. Respiration during wakefulness is influenced by not only automatic control but also voluntary and behavioral control. Sleep is associated with definite changes in respiratory function. With the onset of sleep, voluntary control of ventilation that overrides automatic control during wakefulness becomes terminated. Also ventilatory response to various stimuli including hypoxemia and hypercapnia is decreased. With these reasons respiration during sleep becomes fragile and unstable so that marked hypoxemia can be happened in patients with lung disease especially during REM sleep. Obstructive sleep apnea may also be developed if upper airway resistance is increased in addition to these blunted ventilatory responses.

Backgraund : Most of the inflammatory bullous lesions in bullous pamphigoid(BP) and epidermolysis bullosa acquisite(EBA) demonstrate similar clinical and histological features. However, the specificities of the autoantibodiea reactive to the dermo-epidermal junction antigeins are different. In these two bullouk dermat loses, there are no remarkable differences in symptomaiology, there are no unique predilection sites for the lesions and they do not usually leave scars after nvolution. Considering these similarities, dermatologists could encounter some clinical confuiion in maling a provisional diagnosis. OBJECTIVE: Authors examined three patients of BP with classic inflammatory bullous eruptions and threa patients of EBA with inflammatory bullous lesions to see if here were any differences in the morphology of the immuno-fluorescence(IF) pattern. METHODS: For direct IF of vertical or semi-vertical sections, perilasional skin was obtained in each patient for indirect IF of horizontal or semi-horizonta1 sections, Ig(bound substrates were prepared from all these autoantibody-positive individuals. All specimens veri; observed at 200/400-magnification fields through an ordinary fluorescence microscopy. RESULTS: Patterns of fluorescence observed by direct IF were characterized as thin-linear in BP and thick/coarse-linear in EBA along the basement membrane zone. On the horizontal section preparations in indirect IF, the patterns of fluorescence were clean-linear in E3P hnd more fluffy-linear in EBA at the dermoepidermal junction, These patterns could be recognized aim/larly in the fields of both 200 and 400-magnification, however each minor differences were not easy to distinguish each other. CONCLUSION: The above findings of subtle differences in the pattern of IF may provide some suggestions to the examiners for the need of differential diagnosis in theae riseases.

Growth factors influencing the function of chondrocytes are insulin-like growth factor I(IGF-I), basic fibroblast growth factor(bFGF), transforming growth factor-beta1(TGF-beta1), and epidermal growth factor(EGF). To find out the role of four kinds of growth factors in the biosynthesis of type I and II collagen represented as the phenotype of the disc cells, we cultured the disc cells isolated from rabbit intervertebral discs primarily and then checked cell proliferation, the expression of type I and II procollagen mRNA, and the immunohistochemical stains with type I and II collagen antibodies during in vitro culture in the maintenance medium containing low serum concentration with adding four kinds of growth factors. The results are as follows. FBS(10% Fetal bovine serum) group showed the highest cell proliferation potential. EGF and TGF groups showed remarkable cell proliferation, but there was no significant difference in IGF and FGF groups comparing to control group. A partial clone that encodes the rabbit type II procollagen C-propeptide region(RbCo12A1) was successfully isolated by reverse transcription-polymerase chain reaction using total RNA extracted from articular chondrocytes of rabbits. The identity of the cDNA clone was confirmed by DNA sequencing of the polymerase chain reaction products. A comparison of human al(II) cDNA sequence showed high sequence homology(83.6%). Type I procollagen mRNA expressed highly in EGF group. FGF, IGF, and TGF groups showed no significant expression comparing to control group. FBS group showed lower expression than control group. Type II procollagen expression was increased with passage of time, so at Day 10 it was the highest in all groups. Control group showed the highest expression among 6 experimental groups. The expression of type II procollagen in FGF and TGF groups was slightly lower than that of control. EGF and IGF groups showed markedly decreased expression comparing to control group. That in FBS group was the lowest, so it was three times lower than control group. In immunohistochemical stains with type I collagen, there was no difference among control, FBS, and EGF groups. FGF, IGF, and TGF groups showed increased positivity on stain comparing to control group, but the positivity didnt exceed 10%. For type II collagen, EGF and FGF groups showed decreased positivity, but there was no significant difference in FBS, IGF, and TGF groups comparing to control group. On the basis of this study, it may be concluded that TGF-pl showed the possibility of regeneration or delay the degeneration process of the intervertebral disc through the contribution to the stimulatory effects of cell proliferation and the synthesis of type II collagen. For the clinical use of this, more studies about the combination effects with FBS or other kinds of growth factors and finding out the ideal concentration about TGF-pl will be needed.

Fractures of the body of the talus are extremely rare, constituting only about 0.1 percent of all fractures (Coltart 1952). Consequently, the prognostic problems have so far been elucidated only on the basis of few reports in the literature. The authors experienced an unusual type of the shearing fracture of the talar body with total disocation that the talar body was lying upside down in the ankle joint. Satisfactory results were obtained after follow up period of 20 months and some are reporting this case with bibliographic reviews.
