Bowens disease is generally regarded as a premalignant dermatosis. If untreated, 3% to 5% of patients may develop squamous cell carcinoma. However, sebaciou carcinoma arising from Bowens disease is very rare. We presented a case of quarnous cell carcinoma and sebaceous circ s disease in a 68 year-old male. He had multiple bowenoid skin lesi nsties. A bean-sized nodule as developed on the bowenoid lesion of the he had a large yellow crust.ed exudative tumor on the Rt. thigh. We took a biopsy specimen of these three discrete lesions. The nu lipid stain of frozen section revealed Bowens disease, squarnous concllnoma arising from Bowen on the trunk and extremi Rt. lower abdomen. Almost of routine histology and carcinoma, and sebaceous carcinoma, respectively.

Holter ECG monitoring is a continuous tape recording of a patient's electrocardiogram during ordinary activities and picks up hidden abnormalities in rate, rhythm or conduction. The authors delineated the types and incidence rates of arrhythmia in 32 normal Koreans by utilizing medical personnels and patients without evident heart diseases or symptoms, or significant systemic illness. Tracings and analysis were performed using 24 hour Holter monitoring processor(SCM 240, Fukuda, japan), auto-analyser (SCM-25), casette recorder(SM 24) and chrome tape. Results are as follows: 1) Portable 24 houre Holter ECG monitoring was performed in 32 persons(age range of 21 to 35) without cardiovascular disease, as defined by normal clinical and noninvasive cardiovascular examination. 2) During exercise, maximal heart rates ranged from 125.0+/-12.1/min and minimal rates from 96.7+/-5.8/min. During normal activity period, maximal and minimal heart rates were, respectively, 95.4+/-16.2/min and 62.6+/-6.3/min. Maximal sleep rates were 90.3+/-26.6/min and minimal sleep rates 57.4+/-12.4/min. 3) P-R interval decreased as heart rate increased. Transient first degree AV block was noted in 3 subjects(9.4%) and Wenckebach type second degree AV block in 2 subjects(6.3%). 4) Sinus tachycardia and bradycardia were observed in all subjects and sinus arrhythmia was more frequently noted during waking periods. Three subjects had episodes of sinus pause with maximum duration of 3.24 seconds. 5) In 13 persons(40.6%) having supraventricular premature beats, the frequency was 50.01+/-49.36/hr and in 14 persons having(44%) ventricular premature beats the frequency 26.33+/-18.83/hr. Transient ventricular tachycardia of 3 seconds' duration was observed in one subject under the extreme stressful environment. 6) ST segment elevation over 1mm was noted in 5 subjects(15.6%), of whom one had a nocturnal chest pain and ST segment depression over 1mm in 2 subjects. T wave inversion was also found during exercise(3.1%) and during sleep(9.4%).

Left ventricular hypertrophy is a compensatory response to hemodynamic overload secondary to an increased systemic resistance. This increase, however, is not the only cause of hypertrophy, and there are other factors which can have a significant effect on its incidence. To determine whether chronic antihypertensive therapy by enalapril modifies the cellular and subcellular changes of left ventricular hypertrophy observed in spontaneously hypertensive rats(SHR), 20-weeks-old SHR were treated for 22 weeks with enalapril(2mg/kg) and compared with normotensive Wister-Kyoto rats and not-treated SHR. Systolic blood pressure in enalapril-treated SHR was significantly lowered after 22 weeks compared with that of untreated control SHR group. Myocytes were reduced in size and fibrination seen in cardiac muscle fibers of control SHR was decreased in treated SHR group. Myofibrils appeared to be irregular in shape and myofilaments are decreased in control SHR but in enalapril-treated SHR the diameter and length of the myofilament became turned to regular forms. These results suggest that, enalapril, angiotensin converting enzyme inhibitor, may regress hypertrophy and some subcellular changes may be modified by enalapril.
