RESUMO
Hatchery seeds released into open coasts for wildstock enhancement are often a biological pollutant and affect the recipient ecosystem integrity. We studied morphological changes in two hatchery populations of the starry flounder Platichthys stellatus; one released into the open coast from the hatchery (released population) and the other kept in the hatchery (captive population). The released population differed significantly from the captive population 3-36 months after release from the hatchery. Two-way ANOVA comparison revealed that 11 of 15 starry flounders differed significantly in morphological measurements, 10 of 15 differed in pigmentation, and 5 of 15 differed in morphometric ratios between the two populations. Pigmentation on the blind side (a representative sign of captive flounders) also differed between the two populations with an occurrence rate of 22.7% for the former and 39.5% for the latter groups. The released population was more similar to wild populations than to captive populations in terms of morphology; namely, longer and broader heads, a narrower body shape, longer fins, and a shorter and narrower peduncle.
RESUMO
PURPOSE: In this study, we introduced a newly developed technique of operation for hallux valgus. We used a single dorsal incision to correct major components of Bunion in stead of two or three incisions, which had been used by most of surgeons for long time. MATERIALS AND METHODS: Between 2003 and 2005, 27 feet with hallux valgus deformity were operated through single dorsal incision. 10 out of 17 patients underwent operation on both feet, 5 patient underwent operation on left feet, remaining 2 underwent operation on right. There were 16 women and 1 man. Average age of patients was 45 (range, 21-59). Post operatively all feet were evaluated by physical examination, Maryland Foot score profile, radiographic measurements and complication. RESULTS: Maryland foot score profile increased from preoperative 67/100 to postoperative 95/100. Most patients satisfied pain relieve and cosmesis. Average preoperative intermetatarsal angle was 15 degrees, which were decreased to 9 degrees after operation and average preoperative hallux valgus angle was 32 degrees, which were decreased to 12 degrees after operation. CONCLUSION: According to our experience, the single dorsal incision technic for correction of moderate to severe hallux valgus deformities was rather safe and easily performed without noticeable complication with almost same results as multiple incisions technics. We highly recommend this technic to be tried by foot surgeons without hesitation.

Brodie's abcess, a local form of subacute osteomyelitis, is a rare disease and usually occurs in the metaphysis or epiphysis of the long tubular bone in young adults. Generalized symptoms and signs resembling infectious disease are uncommon. Abnomalities in laboratory findings are not severe. Because of these characteristics and nonspecific radiology, there are difficulties in the differential diagnosis with other infectious disease and tumorous conditions. The authors experienced a case of Brodie's abcess in the proximal tibia bilaterally.
