A comparison of the absorption and incorporation of C(14)-proline into protein by the 7 kinds of helminth parasites is presented. The radioactivity of free amino acid fraction is greater than that of protein fraction in all the worms, and only a small amount of exogenous labeled proline is incorporated into tissue protein. In general, the pattern of C(14)-proline uptake and its incorporation into protein shows rapid linear increase during the period of 15 to 30 min and reaches the maximum at 60 min after incubation, and then the equilibrium state was maintained throughout further incubation.

BACKGROUND: Transforming growth factor-beta(TGF-beta) has multiple regulatory effects on cells of the immune system, and it has been suggested that differentiation of lymphoid cells is influenced by low concentra tions of this cytokine. OBJECTIVES: The aim or this study was to investigate the role of TGF-beta in regulation of T cell growth and differentiation, and to compare this effect with that of other cell signals known to be important in T cell ontogeny. METHODS: We used the CTLL-2 cell line in the presence of IL-2. Surface phenotype expression was analysed to see whether these cells could be switched to the other subtype of cells. RESULT: Treatment of CTLL-2 cells with TGF-beta resulted in dose dependent growth inhibition and morphological changes. Curing routine passage, less than 5% of cells were CD8alpha positive, whereas 38% of cells expressed CD8alpha when treated with IL-2 plus TGF-beta. However, TPA plus calcium ionophore, IFN-gamma, or TNF-alpha caused no significant changes in the proportion of CD8 cells. CONCLUSION: Our results show that this experiment can be a useful model for investigating CD8 precursor potentials in populations of CD4-CD8-(double negative) cells, and such a model may offer a way to study the molecular regulation of CD8 gene expression.

Direct contact method of autoradiography was utilized in studying the distribution of exogenous C(14)-proline in Clonorchis sinensis, Eurytrema pancreaticum, Hymenolepis diminuta and Dipylidium caninum. The most distinct autoradiogram were obtained after 60 min of incubation, corresponding to the maximal absorption of C(14)-proline in these parasite. The radioactivitity of this labeled amino acid was chiefly concentrated in reproductive organs, especially egg-containing uterine tubules.

The autogenous fascia graft has been used for various surgical purposes because it has good durability, a gliding capacity, elasticity and a high survival rate. However, few studies have reported histological changes of the graft in various situations. This study attempted to determine histomorphologic changes after autogenous fascia graft in various surgical conditions. The results revealed were as follows: 1. The tension applied to grafts plays the key role in the survival rate of autogenous fascia grafts. 2. Rolling the fascia reduced the volume and weight after autogenous graft due to fibrosis and central fatty degeneration. 3. Autogenous fascia graft covering silicone blocks showed its fascial structure and reduction of the formation of fibrous capsule around the silicone.

Actinomycosis is a chronic suppurative and granulomatous disease characterized by peripheral spread and extension to contagious tissue, rare hematogenous spread, and the formation of multiple draining sinus tracts. In the rare case of hematogenous disseminated Actinomycosis; lesions appear in all parts of the body. Bone involvement, however, is very rare except the jaw and there has been only some reports about the ribs and vertebral columns. To our knowledge, this case represents the first report of documented distal femoral involvement.

Bullous pemphigoid(BP) and herpes gestationis(HG) are subepidermal bullous diseases which show clinical and immunological similarities. Both diseases show immune deposits along the basement membrane zone and their autoantibodies bind a common antigenic site within the non-collagenous stretch of the 180 kDa BPAG2 ectodomain. Besides its association with pregnancy, HG has some characteristic features that distinguish it from BP. The serum of patients with HG often contains an IgG that avidly fixes complement, and showes IgG1 subclass predominance. We report here two cases of non-pregnant young women presenting clinical and histological features of bullous pemphigoid or herpes gestationis. The immunopathology, IgG subtyping and immunoblotting studies showed that the autoantibodies in the patients were the characteristic ones of herpes gestationis. The patients might be a subtype of BP that have characteristics of autoantibodies of HG patients.

OBJECTIVE: The purposes of the present study were to investigate the effect of gamma-radiation on the expression of inhibin-alpha proteins and genes for inhibin alpha, betaA, and betain the ovary. METHODS: Immature mice were whole-body gamma-irradiated with 25% of a lethal dose. At time 0, 3, 6, 12, and 24 hours after the irradiation,the ovaries were collected and used for immunohistochemistry for inhibin-alpha, and RT_PCR for inhibin-alpha, betaA, and betaB. RESULTS: The expression of the immunoreactive inhibins-alpha was maintained at 12 hours post-irradiation and reduced thereafter. The expression of inhibin-alpha mRNA was significantly increased with the time after the irradiation. However there were no significant changes in the expression of betaA and betaB mRNAs. CONCLUSION: It might be thought that inhibin acts as one of the regulatory factors in the gamma-radiation-induced follicular atresia in mice

The importance of vegetables as a allergen for the development of hand eczema has been a matter of debate. The aim of this study was to evaluate the clinical manifestations of hand eczema and to investigate the role of vegetables in the hand eczema of Korean housewives. In this study, clinical evaluatons and patch tests with Hollister-Stier standard allergens and 22 vegetable allergens wer performed in 32 patients with housewife's hand eczema. The results are summarized as follows : 1. The prevalence was highest in fourth(59.4%) and third(25.0%) decades of life and the peak age of onset was third(53.1%) and fourth(31.3%) decades. 2. Only 3 of 32 patients(9.4%) had past histories of atopic dermatitis ; however, childrens of 12 patients(37.5%) had atopic dermatitis. 3. The common skin signs were fissuring(90.6%), scaling(78.1%), erythema(75.0%), hyperkeratosis(71.9%), lichenification(62.5%), and vesicle(43.8%) in descending order. 4. The common aggravating factors were soap or detergent(93.8%), water(90.6%) and rubber glove(25.0%). 5. The most common involved areas of hand eczema were fingers including fingertips and fingertips only. 6. The results of patch test using vegetable allergens with 10 normal controls were all negative. Of the 32 patients with hand eczema, 13(37.5%) showed positive patch test with standard allergens and 5(15.6%) showed positive with vegetable allergens. 7. Among 30 standard allergens, cinnamic alcohol(9.4%). potassium dichromate(9.4%), nickel sulfate(6.3%), and wool wax alcohol(6.3%) were the common allergens which showed positive reactions. Of the 22 vegetable allergens, garlic, Chinese cabbage juice, Chinese cabbage extract, cucumber juice, spinach extract, potato juice showed weak positive reactions in only one patient(3.1%) respectively. From the above results contact sensitivity to vegetables is not significant in Korean housewives with hand eczema.
