It has been well known for a long time that Rhus species are belonged botanically to same family called family Anacardacea and their allergenic components are identical because it contains 3-pentadecyl catechol. However, Mason (1954) and some investigators suggest the possibility that some individuals may be sensitive to a component of the oleoresin other than 3-pentadecyl catechol. By this suggestion, author performed the patch test on 138 individuals with 4 species of Korean Rhus tree (Rhus verniciflua, Rhus trichocarpa, Rhus javanica, and Rhus sylvestris.) and observed the incidence of latent sensitivity to dry leaves of Rhus trees and urushiol, The patch test results on sensitivity to Rhus verniciflua, Rhus trichocarpa, Rhus javanica, and Rhus sylvestris showed 35.50%, 27.53%, 21.01%. 28. 26%, and 29. 71% respectively and these results could make the suggestion that cross sensitivity between each Rhus trees are few and a certain specific antigenic component may be contained in every Rhus tree leaves. On animal experiment concerning the basic study for the extraction of Rhus tree antigen, author could easily sensitize the guinea pig with urushiol but couldn't challenge these animal with methanol aceton extract of Rhus leaves. From these findings, author proposed that Korean Rhus trees are different immunologically to poison ivy tree antigen and a certain specificities of antigeniciy contain in each Korean Rhus. But this postulation will need further experimental study as multiple step fractionation with Rhus tree.

A case of dermatitis herpetiformis associated with bronchogenic carcinoma is reported. The 56 year-old female patient developed cough with expectorants and exertional dyspnea one year ago, and also showed the pinhead to rice sized erythematous papulovesicular eruptions on the back and extremities with severe itching sensation one month ago. Bronchogenic carcinoma was confirmed by chest X-ray and so on. Skin biopsy was performed on the vesicular lesion and reveled subepidermal bullae with eosinophilic and neutrophilic inflammatory cells infiltertaion.

We Reviewed 10 hypertensive children with pheochromocytoma retrospectively and the following results were obtained. 1) Out of 10 patients, 7 were male and 3 female. Age ranged from 5.5 years to 13.8 years and their median age was 9.9 years. 2) They complained of sweating, lethargy, headache. or chest pain and so on. Hypertension were noticed in all patients. Heart murmurs were detected in 7 patients and hypertensive retinopathy in 70%. 3) The three cases arised at extraadrenal gland and bilaterality was seen in 3 patients. In the view of diagnosis, abdominal sonography, computerized tomography and urine VMA test revealed the sensitivity of 100%. But MIBG scan showed 60% in sensitivity. 4) Waiting for operation, their hypertension were controlled by adrenergic blockers or calcium channel blockers. They received tumorectomy successfully except one who was in hypertensive state after operation and followed up through OPD. In conclusion high suspicion for the existence of pheochromocytoma from the clinical manifestations should be entertained in any pediatric patients and biochemical and imaging studies were mandatory. Furthermore, for the accurate localization of tumors, several imaging studies should be collaborated.

Sulfuric acid can cause local or systemic effects after exposure by inhalation, ingestion, or topical application. Direct ingestion is the main exposure route for fatal sulfuric acid injury. Fatal accidents involving the inhalation of toxic sulfuric acid vapors are rare. Inhalation of sulfuric acid fumes causes severe irritation or corrosive damage to the upper respiratory tract. Consequently, severe congestion, edema, and inflammation of the mucous membranes of the upper respiratory passages hinder the entry of air into the lungs, possibly leading to fatalities in victims. A 35-year-old man died at his home after complaining of a severe sore throat. One day earlier, he had worked in a sulfuric acid tank in a copper-smelting plant while wearing an ordinary gas mask that offered no protection against sulfurous acid vapors. Upon autopsy, the larynx and epiglottis showed pronounced edema, congestion, and inflammation that histologically mimicked an acute bacterial suppurative inflammation, accompanied by severe pulmonary edema. A field analysis of the air inside the sulfuric acid tank revealed SO4(2-) positivity and a 40% sulfuric acid concentration.

The author investigated the allergic contact dermatitis patients which visited our out-patient skin dispensary during 1969 and 1970. The patients were evaluated arcording to age, sex and cause of the disease. Furthermore, the patients were analysed as to the causative allergic contact factors by clinical inspection and history. The causes were confirmed by the patch test which was done on 88 of the allergic contact dermatitis patients. It is believed that patch test is clinically a most reliable procedure for the determination of responsible antigenic substance in allergic contact dermatitis and the positive reactions may be labelled as latent or potential hypersensitivity(Hjorth et al, 1968; Maibach, 1965). There is a group of chemicals used on the so-called routine screening patch test tray, which have proved to be frcquent causes of allergic contact dermatitis. Many diagnostic groups of chemicals and therapeutic trays, shoe trays, metal trays, etc., in addition to the standard routine screening patch test tray are used. Certain allergens seem to cause dermatitis in all countries hut many sensitizers vary from one country to anothcr (Calnan, 1955), The author has tried to establish a standard routine screening patch test tray fitted to our country according to the basic consideration used with standard routine patch test trays of the Skin and Cancer Unit, New York University Hospital. Paraphenylene diamine, ammoniated mercury, mercury bichloride, formalin, crude coal tar, potassium dichromate and mercaptobenzothiazole were the most potent sensitizers. These chemicals must be included in our standard screening routine patch test tray. However, the patch test results and the present clinical dermatitis (i.e. cosmetic dermatitis and rubber or leather dermatitis) did not coincide. Further investigation for the establishment of a proper stanard patch test tray for Korea should be carried out.

The authors report a case in which a cerebral arteriovenous malformation(AVM'S) disappeared completely and spontaneously within 7 years without bleeding episodes or surgical intervention. During the interval, he has been completely asymptomatic and had received no treatment except anticonvulsant medication for 6 months. There was no more epilepsy and mild muscular atrophy in the right lower extremity. A similar case has previously been described and is discussed briefly along with other cases of complete AVM'S regression.
