A malformation of azygos and hemiazygos system were observed from the cadaver for anatomy practice in College of Medicine, Chungnam National University. The observing results were as followings ; Hemiazygos vein was connected with left superior vena cava and drained into coronary sinus, which engorged enough to fill up with blood about 20cc to 30cc. Communicating pathway from hemiazygos vein to azygos veln wasn't found the diameter of left brachiocephalic vein was very small, about 2mm to 3mm. And, the diameter of left internal jugular vein was smaller than that of right infernal jugular vein. In this case, the azygos and hemiazygos system ceased its development at early embryologic stage(around 7 week embryo) and didn't progress into next stage.

The eosinophilia-myalgia syndrome associated with ingestion of L-tryptophan in man is defined by the CDC(1989) as follows: 1) eosinophil count more than 1,000 cells per microliter; 2) generalized myaligia(at some point during the course of illness) of severity sufficient to affect a patient's ability to pursue his or her usual daily activities; 3) no evidence of any infection(e.g., trichinosis) or neoplasm that would explain either the eosinophila or the myalgia. The pathologic findings of the eosinophilia-myalgia syndrome varies according to the degree of severity and types of inflammatory cells in the skeletal muscle. In order to simulate this syndrome in animals and further determine its histopathogenesis, L-tryptophan was administered to rats in the laboratory at various doses(25 mg/kg, 50 mg/kg, 150 mg/kg) over a set period of time. In this study, positive histopathologic findings were designated according to the inflammatory cell infiltration of the epimysium and epineurium. Most of the pathologic findings in the positive group were that of inflammatory cell infiltration composed mainly of eosinophils in the epimysial, epineurial connective and surrounding adipose tissues. Only a few necrotic muscle fibers were seen, and there was absence of any evidence of inflammatory cell inflitration in endoneurium or axonal degenerations. Of 59 rats which were given L-tryptophan, 27 rats(45.8%) met the criteria and were designated as belongintg to the positive group. Only 2 rats ingested with L-tryptophan(150 mg/kg) for 2 months and 4 months showed an eosinophil count more than 1,000 cells/microliter. The eosinophil count in the positive group showed significantly different levels when compared to the the negative group and control group. On the other hand, there were no significant differences in the electrodiagnostic study and serum CK, SGOT, SGPT level between the positive, negative and control groups. In summary, histopathologic findings similar to the eosinophilia-myalgia syndrome were inducible in rats followign the administration of L-tryptophan.

Cutaneous leishmaniasis (oriental sore) is usually a self-limited infection of the skin caused by the protozoan Leishmania tropica. The disease is endemic to the Mediterranean, Asia, Africa, and the Middle East. It has been seen in this country among many Korean technical experts and labourers working in the endemic areas of the disease. Our patient had acquired cutaneous leishmaniasis in Saudi Arabia and it had remained active for six months. He had been treated with antimony and metronidazole but failed because of severe side effects. And then we treated the patient witb cryosurgery and the skin lesions were followed by resolution with cosmetically acceptable scar in 4 months. The brief review of literature on the treatment of cutaneous leishmaniasis was undertaken.

Bezoyl peroxide, a powerful oxidizing agent, has been uaed topically in the treatment of acne vulgaris as a cream or lotion and has been shown to he effective for this codition. In 1972 Fulton emphaaized the importance of the vehicles used to obtain. maximum potential of benzoyl peroxide and for this, the gel formulation has been examined in many clinical trials. The present study was undertaken to evaluate the therapeutic effect of Fanoxyl 2.5, a 2.5% . benzayl peraxide gel, in patients with acne vulgaris. A total of 31 patients entered this study at the Departrnent of Dermatology, Jeoul National University Hospital rluring 3 rnanths period, from Decemher, 1978 through February, 1979, All patienta were instructed to apply Fanoxyl 2.5' on their affected areas once or twice a day and the nurnber of lesions on two or three t fixed areas were counted before and onee weekly after initation of the treatment. The reaults observed in the 3I patients were as follaws; 1. The percentage decrease in total nurnber of lesions in 4 weeks after treatment was 56.9%. 2. The authors could follow up for 6 weeks in 6 cases. In 6 case, the mean percentage in total number of lesions in 6 weeks after treatment was 81.7%. 3. Clesed and open eomedones were gradually eliminated; and their numbers were decreased in 4 weeks after treatment by 46.5% and 56.8% respeetiveIy. The papules were rapidly eliminated and their numbers were decreased in 4 weeka, after treatment by 79.8%. 4. Although most patients felt a mild burning sensation and tightness at the begining of the treatment, only a minority of the patients complained of discomfort due to pain(l case), erytherna(l case), tightness(2 cases),burning sensation (1 case), scaling(1 case). But all were tolerable without taking any specific measures or discontinuance of application. In one case, contact dermatitis developed after 4 weeks treatment. The authors concluded through this experiment that Panoxyl 2.5' (2.5% benzoyl peroxide gel) is a very effective local therapeutic agent in the treatment of acne vulgaris patients.

We report a case of cerebriform intradermal nevus. a cause of cutis verticis gyrata that clinically they resembled neurofibroma and revealed histopathologic finding consistent with intradermal nevus. The patient was a 6 year-old boy, who had a 17x18cm, soft, convoluted. pigmented mass over the parietal and occipital regions. The lesion had been present since birth and had been slowly increasing in size with convolution.
