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.

8.A Case of Impetigo Herpetiformis Terminating in Fetal Death.

Impetigo herpetiformis is a form of pustular psoriasis that occurs during pregnancy and may be life-threatening. The pathogenesis and etiology of impetigo herpetiformis is not clear, but several reports have associated onset of this disorder with hypocalcemia, hypoparathyroidism, and the use of oral contraceptives. The typical lesions are erythematous patches that are studded with tiny superficial pustules particularly coalescing at their margins causing pain, and a burning sensation. Laboratory findings include an elevated erythrocyte sedimentation rate, increased peripheral blood leukocyte counts, hypoalbuminemia, and in severe cases, hypocalcemia. The histopathology is the same as that of pustula psoriasis. Our patient, a 31 year-old female (Intra Uterine Pregnancy 28 weeks), was admitted to our hospital due to generalized skin eruption and severe constitutional symptoms. Her clinical features, laboratory and histopathologic findings were compatible with that of impetigo herpetiformis. In spite of our all efforts, intrauterine fetal death was noted at her 33rd week of pregnancy. We report a case of impetigo herpetiformis terminating in fetal death with the review of literature.

9.Prophylactic Intravesical Chemotherapy in Superficial Bladder Tumors.
Eui Hyun CHANG ; Sung Choon LEE
Korean Journal of Urology 1985;26(5):425-432
Superficial bladder tumors are usually treated by TUR. However, recurrence of the tumor after complete resection occurs in about 50-70%, of the patients with a significant percentage of these recurrences showing a higher degree of malignancy. In 10% of the cases, the tumor progresses to invasive carcinoma. Most of these recurrent tumors will occur within 6-12 months. The multifocal nature of these tumors and the frequent recurrences after TUR indicate a need for adjuvant chemotherapy to reduce or delay the incidence of recurrence tumors. We studied to evaluate prophylactic effects of topical chemotherapy in 116 cases with superficial bladder tumors admitted to the Department of Urology, Keimyung University School of Medicine during the period from Jenuary, 1971 through July, 1985. All patients were followed up for more than 6 months. Study group consists of 83 cases (Thio-tepa: 39, Adriamycin; 44) treated with topical chemotherapy following TUR during the period from January, 1978 through July, 1985. Control group consists of 33 cases treated by TUR only during the period from January 1971 through December, 1977. Following results were obtained: 1. No. of patients with recurrence; In study group, 36Pr In control group. 67% 2. Average interval of recurrence: In study group, 38 months. In control group, 30 months 3. Recurrence rate; In study group, 2.58 In control group, 3.16 4. Complication: local side effects; In TUR + Thio-tepa, 20.5% In TUR + Adriamycin, 15.9%.
