Hemoglobin Concentration in Female Workers of Occupational Exposure to Lead / 영남의대학술지

This study was conducted to evaluate the effects of lead on the incidence of anemia and to find cases with lead poisoning early among female workers who have been exposed to lead occupationally, for one year from August, 1985. The level of blood lead and hemoglobin concentration were observed for 284 female lead workers and 123 female non-lead workers of industries in the Gumi industrial complex in Kyungpook Province. The average age was 20.3±2.9 years and 21.1±3.5 years in lead workers and non-lead workers, respectively. The average working duration was 26.46±19.26 months in lead workers. The mean value of blood lead was 30.11±6.61 µg/100 ml and 21.86±3.75 µg/100 ml in lead workers and non-lead workers, respectively. There were significant differences between two groups. The mean value of hemoglobin concentration was 14.00±0.57 g/100 ml and 14.03±0.64 g/100 ml in lead workers and non-lead workers, respectively. Anemia cases were not observed at Hb concentration below 12g/100 ml. The percentages of lead workers at Hb concentration ranged 12.0~13.0 g/100 ml were 4.5%. There was no dose-response relationship between blood lead level and the incidence of anemia. There were no remarkable differences between age and blood lead level as well as Hb concentration, and between working duration and the level of blood lead and hemoglobin.

A Study on Disposal of the Color-defective Person in the Enterance Examination for University

The authors analyzed the disposal of the color-defective person in the enterance examination of 24 colleges of natural science among 31 colleges that replied the questionaire sent by us to 70 Universities and colleges in Korea. The results revealed that there was no standard for permission or limitation of the color-defeetive person.

A Case of Malignant Melanoma of the Choroid

The author reported a case of maligmamt melanoma of the choroid. The patient, 23-year-old male, visited our hospital in sep. 1974, with blurring vidon (O.D) since 40 days ago. The tumor suspected to malignant melanoma was visible through clear media. Enucleation was performed and the histopathological examination revealed choroidal malignant malanoma composed of spindle A and spindle B type cells. No evidence of invasion into the optic nerve was noted.

The Lens Dislocation into the Anterior Chamber in a case of Marfan's syndrome

The authors experienced a case of Marfan's syndrome in whom the right sided lens was dislocated into the anterior chamber and the left side inferio-temporally into vitreous. In addition, the lens of the right eye was complicated by cataract, and a favorable outcome was obtained by intracapsular lens extraction.

The Dermatofibroma on the Lower Lid

Dermatofibroma, a benigh tumor, invading eyelid is seldom reported. The authors experienced a case of tumor invading medial part of the left lower eyelid in a patient of eight day of age. The tumor was resected under general anesthesia and histopathological study revealed it to be dermatofibroma.
