The neuromuacular blocking effects of the repeated bolus injection and continuous injection of vecuronium have been compared in 20 patients by means of evoked twitch tension. Group I received a loading dose (0.08 mg/kg) of vecuronium and followed by maintenance doae (0.02 mg/kg) when twitch tension had recovered to 25% of control. Group II received a loading doses (0. 08mg/kg) of vecuronium plus a continuous infusion delivering 0.06 mg/kg/hr. Anesthesia was maintained with nitrous oxide, oxygen and 1.5% enflurane. The neuromuscular blocking effect were reversed by the neostigmine 1.0 mg and robinul 0.2 mg when twitch tension had recovered 25% control in both groups near the end of operation. With repeated injection of vecuronium (group I), the duration of blockade of 25% recovery was 21.6+/-4.2 minutes and the recovery times from 25% to 75% was 6.8+/-1.9 minutes The continuous infusion of vecuronium (group II) produced consistent neuromuscular blockade at the average level of 90% twitch depression. The times from the end of infusion to 25% and fr,om 25% to 75% are averaged 16.0+/-2.5 and 4.2+/-0.7 minutes respectively. The reeovery index was more rapid in infusion group than maintenance group (P<0.05).

Juvenile xanthogranuloma is a congenital or perinatal tumor, 1 to 2 cm in diameter, usually located on the head. The extracutaneous lesions can occur on the eye, the lung, the epicardium, the oral cavity or the testicles. Subcutaneous form of juvenile xanthogranuloma has been reported very rarely in the literature. We report a unique case of a subcutaneous juvenile xanthogranuloma that showed 4 × 4 cm sized plaque and located on the extremity of 9-year-old girl.

Regenerative medicine (RM) aims to replace or regenerate human cells, tissues, or organs to restore or establish the normal function. RM comprises cells, biomaterials for scaffolds, and growth factors. The cells play an important role in regenerative medicine. Biomaterials can form tissue and transmit biological activity signals and promote cell adhesion. The biological growth factor is a signal transmitter necessary to regenerate tissues and organs. Bioprinting as a powerful tool for building tissue and organ structures in the field of tissue engineering has attracted enormous attention as a fabrication methodology for producing 3-dimensional structures. Bioprinting technology will be needed to treat musculoskeletal diseases. This paper will provide information that can be used as a regenerative medicine treatment for musculoskeletal diseases. It will enable the regeneration of the musculoskeletal system consisting of bones, joints, muscles, and nerves.
5.Multiple eccrine nevus with depressed patches.

Yonsei Medical Journal 1997;38(1):60-62
A 2-year-old girl had variably-sized, relatively well demarcated, depressed brownish patches on the left shoulder, back, and both legs from the age of 1 month. The biopsy specimen from the left shoulder showed an increase in the number of normal intradermal eccrine ducts and coils, which was compatible with pure eccrine nevus. The clinical manifestation of our case, including brownish depressed patches, was unique compared to other reported cases.

10.Renal Cell Carcinoma: Review of 28 Cases.
Eui Hyun CHANG ; Sung Choon LEE
Korean Journal of Urology 1983;24(6):981-985
Review of renal cell carcinoma was made on 28 cases admitted to Dept. of Urology during the period of 11 years from September 1, 1972 through September 30, 1983. 1. There were 17 males and females (ratio of 1.5:1) ranged in age from 19 to 69 years with peak incidence in the 6th decade. 2. The most common symptom and sign was hematuria in 75% but the classic triad of this tumor was present in 29%. 3. The abnormal laboratory findings were elevated ESR in 75%, anemia in 64%, and reversed A/G ratio without hepatic metastasis in 14%. 4. On the urogram renal mass was found in 50%, calyceal destruction in 48%, and nonvisualization of kidney in 39%. 5. The renal angiogram of 10 cases demonstrate hypervascularity in 7 cases, hypovascularity in 1 case, and tumor staining in 7 cases. 6. Staging of the tumor revealed stage in 13 cases, stage III in 5 cases, and stage IV in 7 cases. 7. The histological type revealed clear cell in 20 cases, granular cell in 1 case, and mixed cell in 7 cases. 8. Treatments were simple nephrectomy in 16 cases, simple nephrectomy with adjuvant therapy in 3 cases, and radical nephrectomy with adjuvant therapy in 5 cases.
