Author studied on the incidence of intestinal parasites with fecal examination on the out patient Pusan University Hospital, between from January to December 1969. The method employed were Formalin-Ether and flotation method in 3,510 for the prevalence rate of intestinal helminthes(Ascaris lumbricoides, hookworm, Trichocephalus trichiurus, Trichostrongylus orientalis). The following results were obtained: The positive rate of intestinal helminthes of total was 65.4 percent among 3,510 persons. The infection rate of Ascaris lumbricoides, hookworm, Trichocephalus trichiurus, Trichostrongylus orientalis were 19.3 %, 6.5 %, 55.2 % and 46.1 %. The female (66.4%) had definitely higher infection rate than male (65.0 %). The age group of 51-60 year of the male showed highest infection rate 75.4 % and the age group 31-40 year of the female showed highest infection rate 72.9 %.

Livedoid vasculitis is characterized clinically by smooth or depressed ivory-white scars surrounded by hyperpigmentation and telangiectasia with or without preceding purpuric in-filtrated papules and plaques and histologically by intravascular deposition of fibrin. Its pathophysiology is still obscure. Many treatment modalities have been used, but results are not satisfactory. Recently, there have been experiences of successful treatments with danazol, a synthetic androgen. We used danazol in three patients who presented with livedoid vasculitis and were relatively resistant to treatments with aspirin and/or pentoxifylline. After 4 to 8 weeks, there was remarkable clinical improvement in all three patients.

Angiotensin-converting enzyme(ACE) is a ipeptidyl carboxypeptidase that is a membrane bound mainly on the luminal surface of pulmonary endothelial capillary cells. It functions to inactivate bradykinin, and also converts angiotensin 1 to angiotensin Activity of ACE was first identified in plasma by Skeggs and co-workers in ]956 In 1974 Lieberman discovered that elevated levels of serum ACE were associated with active sarcoidosis and that this assay would be usei to assist a diagnosis of sarcoidosis. The association of sarcoidosis and enhanced ACE activity was subsequently supported by data from other investigators. Increased serum ACE levels have also been observed in patients with nongranulomatous diseases and granulomatous diseases including leprosy. The author studied the serum ACE levels in leprosy patients(fourty-three with tuberculoid type and eighty-nine with lepromatous type) and twenty normal healthy controls by the spectrophotometric method described by Lieberman. Comparative studies of ACE levels in these two types of leprosy with normal healthy controls and relationship among the duration of treatment, age, and sex were also conducted. The results were summarized as follows: Ages of the selected patients were between 3Q to 77 years in tuberculoid leprosy (average 54 1), 23 to 75 years in lepromatous leprosy(average 53. 8) and 14 to 49 years in the control group(average 28 4) The duration of treatment in tuberculoid leprosy was between 1 and 39 years and average was 2p 7 years. Of lepromatous leprosy, duration of treatment was between 2 and 50 years and the average was 25. 4 years.

BACKGROUND: Epidermal growth factor receptors (EGFR) have been reported to be absent in melanomas. But recently, the presence of EGFR on melanocytic cells was reported to be a marker of malignant transformation. OBJECTIVE: Our purpose was to investigate the presence of EGFF in melanocytic lesions and to determine whether EGFR presence correlates with the potential or malignant transformation of melanocytic cells. METHODS: We performed the immunohistochemical studies to reveal immunoreactivity of EGFR in 7 compound nevi, 10 intradermal nevi, and four melanomas using the Vectastain ABC immunoperoxidase stain system. RESULTS: Although the intensity of staining was slightly variable, all melanocytic cell types in the studied lesions of compound nevi, intradermal nevi, and melanoms had immunoreactive EGFR. Intense staining far EGFR of all nucleated layers of keratinocytes overlying a melanocytic lesion was also seen. But in the melanoma cells, the staining intensity was modarately deereased. CONCLUSION: Although we found no correlation of EGFR with the potential for malignancy in melanocytic lesions, the high level of expression within nevocytes and lesional keratinocytes suggests EGFR or transforming growth factor a, by acting through the EGFR, plays a role in the pathogenesis, maintenance, or evolution or these lesions.
