Many sensitizing chemicals and additives are used in manifacturing and mending dentures. Among them, phtolyldiethanolamine, a kind of accelerto for polymerization, is necessary only in self-curing acrylic resins which are available for repairing and relining of denture. Although the sotirce of denture stomatitis is still controversial, a true allergy to denture base materials can be recognized by a patch test. We report a case of allergic contact stomatitis due to dentn e relining materials in a 65-year-old denturecariying edentulous patient. Patch testievi.aled positive reaction to polyldiethanolamine which is considerd to be contained in a cold curing acrylic resin fluid.

BACKGROUND: Metallothioneins(MTs) are ubiquitous low molecular weight cytosolic proteins with high contents of cystein that xhibit a selective binding affinity for zinc, copper and other group II heavy metal ions. In additi~on to the sequestration function and detoxification action, MTs probably participate in the cellirlar protection against. ionizing radiation and alkylating agent cytotoxicity and in cellular pn:liferation. OBJECT: The objective of this study was to evaIuate the expression of MTs and to clarify t.heir role in carcinogenesis and/or biological behaviour in the neoplasms of ectoderrnal origin. METHODS: We performed immunohistochemical studies on the surgical specimens of rnalignant rnelanoma and squamous cell carcinoma and basal cell carcinoma. The results were compared with the normal skin and mu osa and hair t,issues and raf't-on culture tissues of skin and mucosal keratinocytes. RESULTS: 1) MTs were strongly expressed in epidermal basal cells of the normal skin and raft-on cultured artificial skin They were also rnore weakly expressed in epithelial basal cells of the normal mucosa and raft on cultured artificial mucosa and in matrix cells of the normal hair. 2) In rnalignant melanoma, MTs were meaningfully expressed, i.e., a strong expression was seen in the lesions showing a rapid vertical growth phase with fatal out,comes, but a weak expression in the cases whose precursor lesions were thought as dysplastic nevi, compared to the negative finding of norrnal melanocyt,es. The strong expression in a case of congenit.al rnelanocyt.ic nevus is considered as the activation of nevoid melanocytes. 3) MTs were weakly expressed in squarnous cell carcinoma with a diffuse aattern within the tumor mass. St,rong expression of MTs was particularly apparent in the poorl. differentiated squamous cell carcinoma and at the growing border of well differentiated squamous cell carcinoma. 4) In basal cell carcinoma, MTs were rather weakly expressed in solid cireumscribed types with a diffuse pattern and in cystic type with a patchy pattern. However they were not expressed in the solid infiltrative type. CONCLUSION: From these resuilts, we concluded that MTs were ubiquitously present in possible stem cells of various epithelial tissues except melanocytes irrespective of normal or artificial skin and/or mucosa including norrnal hair tissues. In the neoplasms of ectodermal origin, MTs might be involved in the invasive growth of tumor cells in the malignant melanoma and squamous cell carcinoma. It was implied that the role of MTs in basal cell carcinoma might be related to early events of hasal cell carcinogeresis and its down regulating tendency could be possible in its infil trative stage.

BACKGROUND: There are many suggested methods for the indirect determination of anaerobic threshold(AT) using the changes of ventilatory parameters in respones to ventilatory load accompanying the increase of blood lactic acid level during exercise and the threshold derived from them is called ventilatory threshold( VT). They include ventilatory equivalent method(VEM), End-tidal PO2 method(PETO2), V-slope method(VSM), and respiratory quotient method(RQ). But in the patients with chronic airway ohstruction(CAO), the AT determined by ventilatory methods may not reflect true AT because the patients with GAO show inadequate ventilatory response to the increase of blood lactic acid level during excercise. METHODS: For the investigation of detection rate and reliability of above four VT determination methods in the patients with GAO, we performed the symptom-limited and maximal incremental exercise test in 17 patients with GAO and 12 normal controls. The incremental workload was 10 W/min in GAO group and 25 W/min in control group. The reliability of VT in each group was investigated by the calculation of Spearman correlation coefficient. RESULTS: The detection rates of VT were 100% by RQ, 91.7% by both VEM and POETO2, and 83.3% by VSM in normal control group, while 94.1% by RQ, 64.7% by VEM and PETO2, and 83.3% by VSM in GAO group. Good correlations were noted among VEM, PETO2, and VSM except RQ in normal control group. But there was no significant correlation except between VEM and PETO2 in GAO group. CONCLUSIONS: RQ is very sensitive but crude and VEM is near similar to PETO2. The clinical usefulness of VT determined by ventilatory method might be limited in patients with severe GAO.

AFX is a fibrohistiocytic tumor which usually shows benign clinical rocess despite malignant histolgy. We report a case of AFX showing storiform pattern distribution of tumor cells which developed on the right temple area of a 70-year-old woman.
