The uterine cervix is an uncommon site of primary non-Hodgkin's lymphoma (NHL). Although the cytologic findings of NHLs are well known, most cervicovaginal smear of uterine NHLs give lower diagnostic yield than common epithelial malignancy because abnormal cells do not appear in the sample in the absence of surface ulceration. Herein, we describe cytologic findings of a case of uterine cervical NHL which was initially diagnosed by cervicovaginal smear. The tumor cells were relatively uniform, isolated, large-sized with scanty cytoplasm and round or indented nuclei. The nuclei had stippled chromatin and small nucleoli. Histologically and immunohistochemically the tumor was proven to be large cell lymphoma of T-cell lineage.

We report a case of eosinophilic pustular folliculitis in a 42-year-old woman who had atypical clinical findings with moderately pruritic erythematous follicular papules and pustules on the face and neck. Histopathologically miny eosinophils and neutrophils infiltrated around the follicles, within the follicles and around tbe vessels. The follicular walls showed spongiosis. The differential count of eosinophils in seram was 1.9%. The patient responded well to systemic steroid and dapsone.

In vitro culture of Toxoplasma gondii in HL-60 cells cnd cell-mediated immunity against Toxoplasma in dimethylsulfoxide(DMSO)-induced HL-60 cells, i.e., differentiation into granulocytes, were pursued. HL-60 cells were treated with various concentrations of DMSO, and 1.3%(v/v) for 3 day incubation was chosen as the optimal condition for differentiation into granulocytes. The degree of differentiation was assayed in physiological and functional aspects in addition to morphological point. When treated with 1.3% DMSO for 3 days, HL-60 cells did not synthesize DNA materials beyond background level, and showed active chemotactic response to chemotactic peptide, formyl-methionyl-leucyl-phenylalanine(FMLP). Morphologically promyelocytes of high nuclear/cytoplasmic(N/C) ratio changed to granulocytes of relatively low N/C ratio. The relationships between HL-60 cells or DMSO-induced HL-60 cells and Toxoplasma were examined after stain with Giemsa and fluorescent dye (acridine orange). HS-60 cells did not show any sign of toxoplasmacidal activity but showed intracellular proliferation of Toxoplasma to form rosette for 72 hr co-culture. In contrast, DMSO-induced HL-60 cells phagocytosed Toxoplasma within 1 hr, and performed a process of intracellular digestion of Toxoplasma thereafter. With the above results, it is suggested that phagosome-lysosome fusion is one of the critical events for the parasitism by Toxoplasma or for susceptibility of host cells. The in vitro culture system of this study has offered a defined condition to study the protozoan parasite-host cell interactions.

Segmental wiring to treat the unstable fracture and fracture-dislocation of the thoraco-lumbar spine is more effective method than Harrington instrumentation as primary procedure which afforded immediate rigid internal fixation of the spine and permitted mobilization without external support and immediate rehabilitation. A clinical study was made of twenty seven patients who were hospitalized and treated at the Department of Orthopaedic Surgery, Wonju Christian Hospital from Feb. 1979 to Apr. 1983. The following results were obtained: l. Of twenty seven patients, nine(33.3%) had a flexion rotation, eight(29.6%) had a shearing, eight (29. 6%) had a flexion compression and two(7.5%) had a vertical compression by Holdsworths mechanism of injury and by Pauls classification of fracture, thirteen(48. 1%) had a flexion distraction fracture, twelve(44. 4%) had a translation fracture and two(7. 5%,) had a unstable burst fracture. 2. Fifteen(55. 6%) had a complete neural deficit and five(18. 5%,) had an incomplete neural deficit. Six(22.2%) of the fifteen patients with complete neural deficit and one(3. 7%.) of the five patients with incomplete neural deficit showed slight neurological recovery, but eight(29.6%) gained complete recovery. 3. Correction of kyphotic deformity was average 12. 4 degree in Harrington instrumentation and average 18. 0 degree in segmental wiring, and during the follow-up periods, there was a final loss of 6. 3 degrees of kyphotic correction in Harrington instrumentation and 3. 0 degrees in segmental wiring. 4. In external support, fourteen(51.9%) had body jacket cast and four(14.8%) had back brace in Harrington instrumentation, but all patients except one brace had no external support in segmental wiring. 5. In complication, two hook dislocations and two pseudoarthroses were occurred in Harrington instrumentation, but any complication except only one cases of wound infection was not occurred in segmental wiring.

The incidence of trochanteric fracture of the femur is increasing, which is likely to continue for many years because of an increase in traffic accidents and the population of elderly people. The primary goal in the treatment of an elderly patient with an intertrochanteric hip fracture is to return the patient to his prefracture activity without any complication, as soon as possible. Rapid mobilization with stable internal fixation helps to prevent skin ulceration, pneumonia, urinary stasis, thromboembolic disease and other complications of confinement to bed in the elderly. Stable internal fixation depends mainly upon the fracture type and operative techniques. A clinical study of operative techniques was done in twenty three patients with trochanteric fracture of the femur who had been admitted and treated surgically at the Orthopaedic Department of W.M.B.H. during of two years from Mar. 1982 to Feb. 1984. The following are brief descriptions of the operative techniques. l. An L-shape incision and refiection of the vastus lateralis muscle provided wide exposure and facilitated anatomical reduction under direct vision. 2. The nail insertion site was selected at a slightly eccentric position anterior to rather than exactly midway from the opposite lateral cortex of the lesser trochanter. Therefore the nail could be laid rigidly between the thick anteromedial cortex and the posteromedial calcar portion. 3. The best stable position among the fracture line, the neck shaft angle and the nail plate could be obtained by the yoking procedure. It also allowed for later proximal migration of the shaft fragment and fracture impaction without impingement on the base of the barrel.

In the case of a soft tissue defect which requires thin & pliable tissues, the choice of donor site is limited due to flap bulkiness and donor site morbidity. To overcome these problems, a variety of perforator-based flaps such as paraspinous and parasacral perforator flap, deep inferior epigastric perforator flap, gluteal perforator flap, and thoracodorsal artery perforator flap have recently been introduced. We experienced 8 cases of soft tissue defects from December 1996 to March 1999 using the thoracodorsal artery perforator flap for reconstruction. We could elevate the cutaneous flap with preservation of the latissimus dorsi muscle flap only when it was based on one cutaneous perforator. Defatting procedure was possible for further thinning of skin flap. In one case, axillary defect after release of postburn scar contracture was repaired with island perforator flap and the other seven cases were repaired with free flap. The results were satisfactory. We believe the thoracodorsal artery perforator flap is useful for reconstruction of soft tissue defects which are large or under conditions requiring thin flap.

BACKGROUND: Sunscreens have been used widely to prevent the photosensitive skin diseases, skin cancer, and skin aging. However, no sunscreen blocks all kinds of effects caused by ultraviolet light(UVL), and the effect of sunscreens on the impairment of immune function by UVL irradiation is controversial. OBJECTIVE: We try to evaluate the efficiency of sunscreens for blocking the depletion of LC induced by UVB irradiation. METHOD: The ATPase positive LCs were observed in the skin of hairless mice(Hr+/Kud) irradiated by UVB with or without topical application of sunscreens. Two commercially available sunscreens with respective SPF 8 and SPF 30 were applied to the dorsal trunk skin. The mice were irradiated with different increasing doses of UVB at a single time. RESULTS: The ATPase positive LCs in the irradiated dorsal and ear skin were significantly de-creased in densities according to the dosage, and apparently revealed a loss of their dendrites, granulation, and clumping from a UVB dose of more than 60mJ/Cm2. With both sun-screen treatment on the dorsal trunk before irradiation, the densities of LCs on the dorsal skin were significantly higher compared to the un-treated groups at all ranges of UVB doses in spite of a dose dependent decrease in their density. However there was no significant difference on their preventive effect between both sunscreens(SPF 8 and SPF 30) except at high UVB dos-es of more than 240mJ/Cm². CONCLUSION: The LC depletion induced by UVB can be partially protected through the topical application of a sunscreen at a UVB dose dependent fashion. However SPF(sun protective factor) dose not appear to be a good indicator for evaluating sunscreens immunologically.
