This study was designed to investigate the effect of substitution of strontium for calcium on mechanical activity in isolated perfused spontaneously beating rat hearts. The mechanical activity of the hearts of Langendorff's preparation in conditions of low calcium and strontium-substitution for calcium was compared. The effect of norepinephrine and verapamil were also observed in those conditions. The results were as follows: 1. In low calcium, the mechanical activity of the heart preparation was significantly reduced, but when the equimolar strontium was substituted for the reduced calcium, the activity was kept at similar level to the normal condition. 2. When equimolar strontium was substituted for the total calcium in perfusate, the heart preparation stopped its beating, and it was not restored in spite of reperfusion with normal calcium perfusate. 3. Norepinephrine-induced positive inotropic effect was inhibited in low-calcium condition especially with low concentration of norepinephrine, but not in strontium-substitution for calcium. 4. Verapamil reduced the activity of the heart both in low-calcium and strontium-substitution as well as in normal calcium conditions. From above results, it was concluded that strontium served as a substitute of calcium in maintaining mechanical activity and in responsiveness to norepinephrine, and the influx of strontium through cell membrane is inhibited by verapamil as the influx of calcium.

Cutis marmorata telangiectatica congenita, which was first described by Van Lehuizen in 1922, is characterized by the presence at birth of a persistent cut;is marmorata pattern, phlebectasia, spider nevus-like telangiectasia, and areas of ulceration and steady improvernent with time. We reported a case of cutis mar.morata telangiectatica. congenita occuring in a 70 days old female infant showing the reticulated mottling and atrophy of the skin on the both lower extremites, right upper extremity, abdomen and buttock muscle weakening of right upper extremity and left lower extremity compare with the opposite side. Skin lesions were much improved during the observation period of 10 months without any other specific treatment except hermiatrophy of right upper extremity.

Cutaneous metastases from internal carcinornas are relatively rare. The frequency of metastases to the skin varies from 0.5-4.4%. We report a case of cutaneous metastasis suspected to originat from stomach cancer. A 44-year-old female, who had an episode of total gastrectony under diagnosis of stornach cancer three years ago, had multipe painless erythernatous nodules on the case and neck for one year. Histologic findings shows atypical anaplastic cell infiltration at the derr is and subcutaneous tissues. Cells with hyperchrornatic and erally displaced nuclei were recogniz d PAS staining shows positive reactions within the cells of glarid like structure. She died twelve month after the appearance of the cutaneous lesions.

The effect of 50 per cent potassium iodide (KI) ointment with occlusive dressing on onychomycosis of the fingers and toes was studiei in 54 patients with 176 diseased nails. The results obtained were as follows. 1. Of a total of 76 fingernails and 100 toenails in 54 patients, all fingernails and toenails showed an excellent response with easy removal of the diseased nails. 2. The duration that the occluded KI aintment remained in place before successful avulsion was 6. 6 (range, 3 to 18) days for fingernails, and 6. 8 (range, 3 to 20) days for toenails with onychomycosis. 8. Of 16 nails of control group which were treated with vaseline, none showed the significant improvement. 4. The problems during this treatment were; mild irritation and/or itching (9 cases), and pin-point bleeding on curettage of nail bed (18 cases). It is suggested that the KI treatment has many advantages and seemed to be an ideal method of treatment of onychomycosis.
