We experienced three cases of non-giant congenital nevus. They showed zosteriform or heart-shaped grouping of pigmented papules which were pierced by hairs. Histopathologic examination disclosed nevus cell infiltration in and around hair follicles and in the upper two thirds of reticular dermis. We would like to report these cases as follicle-centered spotted grouped pigmented nevi.

Korean Journal of Dermatology 1986;24(1):133-135
We present herein a case of sebaceous hyperplasia in a 55-year-old male, who showed multiple asymptomatic yellowish papules on the forehead and the cheeks. Histopathologic examination of a papule revealed numerous sebaceous lobules grouped around several enlarged sebaceous ducts. Three weeks of oral administration. of isotretinoin 40 mg per day brought marked improvement.

BACKGROUND:The biomechanical properties of naturaly regenerated damaged articular cartilage that belongs to the fibrovascular tissue are far worse than those of the normal cartilage so that they cannot meet the requirements for joint function, leading to traumatic arthritis and loss of joint function.
OBJECTIVE:To evaluate the effects of matrix metaloproteinase-3 (MMP-3) inhibitor I with different concentrations on the early-stage repair of ful-thickness articular cartilage defects in the knee of rats.
METHODS: Twenty-four Sprague Dawley rats were randomized into control, defect (DEF), and defect combined with low-(D+L) and high-dose inhibitor (D+H) groups (n=6 for each group), respectively. Full-thickness articular cartilage defects followed by intraarticular injection of low- and high-dose MMP-3 inhibitor I for 4 weeks was administered in the later two groups. Serum MMP-3 was detected using ELISA method before and after experiment, respectively. Femoral trochleas were collected to observe characteristics of repaired tissue by gross appearance scoring and O’Driscoll histological scoring with Safranine O-Fast Green staining, and to measure type II colagen by immunohistochemistry after experiment.
RESULTS AND CONCLUSION:Rats in the D+H group had obvious repair similarly to hyaline articular cartilage, while creamy white cartilage tissue and fibrous tissue repair were observed in D+L group and in DEF group. D+H group obtained the best repair results according to gross appearance scoring and O’Driscol histological scoring and the highest content of type II colagen (P< 0.05). MMP-3 concentration and the difference value before and after experiment were gradualy decreased in DEF, D+L, D+H, and control groups in sequence(P< 0.05). These findings demonstrate that MMP-3 inhibitor I accelerates the early-stage repair of ful-thickness articular cartilage defects in the knee of rats.

A clinical analysis was done on 134 cases with bronchial asthma who were admitted to the Department of Pediatrics Yeungnam University from May 1987 to October 1991. The results were as follows: 1) The peak age of bronchial asthma was under 2 years. The sex ratio of male to female was 2.9:1. 2) The outbreak of bronchial asthma was most common in fall, especially in September. 3) The past history of other allergic diseases were present in 22.4% of patients (30/134 cases), and the previous bronchiolitis in infancy were experienced in 12.7% of patients (17/134 cases). 4) According to the skin test for allergens done by RAST, the most common allergens were Mites and House dust. 5) Eosinophilia (T.E.C>250/min) was found in 29.1%t of patients, and elevated lgE level (>200 IU/ml) was found in 63.2% of patients. 6) No significant differences in the serum lgE level were found between male and female patients. No significant differences in the serum lgE level were found between asthma patients with and without other allergic diseases. 7) The serum lgE level of school aged patients was significant higher than that of preschool aged (p<0.01).

Objective To explore the diagnostic merits of the average apparent diffusion coefficient(ADCav) for leukoencephalopathy in neonates and children.Methods One hundred and fifty-six neonates and children with central nervous system signs or symptoms were classified into 6 groups according to their ages(1 d-0.05).Contrast to the normal,the ADCav of leukoencephalopathy in neonates and children decreased.With increasing age,there showed a linear downtrend in each group.Conclusions The ADCav rises in neonates and children with leukoencephalopathy.The ADCav variation precedes changes in routine MRI.
