Status of Return to Play in Growing Athletes with Lumbar Spondylolysis / The Japanese Journal of Rehabilitation Medicine

Objective：In athletes who are still in the growing period, lumbar spondylolysis is mainly treated with brace therapy to enable bone fusion. During the brace period, sports activities are often discontinued. The purpose of this study was to investigate how the combination of brace therapy and early physiotherapy affects the duration of return to play in athletes with lumbar spondylolysis.Methods：Thirty-seven athletes in the growing period with unilateral spondylolysis were included in the study. They were classified into two groups：17 patients who rested during the brace period（brace group）and 20 patients who combined the brace with early physical therapy (combination group). The examined items were duration of the brace period and duration from the end of the brace therapy to return to play (return period). Both these items were compared between the brace group and the combination group. In addition, the union rate of both groups was also calculated.Results：The return period was significantly shorter in the combination group than in the brace group. However, there were no statistically significant differences between the groups with respect to other data.Conclusion：Since there was no significant difference in the duration of the brace period and the union rate between both groups, we believe that early physical therapy intervention does not adversely affect bone union in athletes with spondylolysis who are in the growing period. Therefore, it is considered that the combined use of brace therapy and early physical therapy can maintain flexibility and muscular strength during the brace period and can enable a smooth transit to playing after the bone union is complete.

Variation of contents of six oligosaccharides in the roots of Morinda officinalis how in different growing periods / 中国药学杂志

OBJECTIVE: To determine the contents of six oligosaccharides, i. e. glucose, fructose, sucrose, 1-kestose, nystose, 1-fructofuranosylnystose, in the roots of Morinda officinalis in different growing periods by HPAEC-PAD method. METHODS: The separation was performed on Hamilton RCX-10 column(4.1 mm × 250 mm, 7 μm) with gradient elution using mobile phase composed of 100 mmol · L-1 NaOH(A) and mixture of 100 mmol · L-1 NaOH and 500 mmol · L-1 NaOAc (B) at a flow rate of 0.8 mL · min-1 and the temperature was kept at 35℃. The injection volumn was 25 μX. The gradient elution program was as follows: 0-5 min, 1%B; 5-15 min, 1%-9% B; 15-20 min, 9%-12% B; 20-25 min, 12%-16% B; 25-40 min, 16%-50% B; 40-43 min, 50% B; 43-46 min, 50%-1% B. RESULTS: With the increase of growing periods, the content of monosaccharide progressively reduced while that of sucrose gradually increased. The contents of oligosaccharides with polymerization degree of 3 or greater, including 1-kestose, nystose, and 1-fructofuranosylnystose, slowly increased during 1-5 years, then slowed down. CONCLUSION: The contents of six oligosaccharides in the roots of Morinda officinalis vary greatly in different growing periods, indicating that the biosynthesis of oligosacchride in Morinda officinalis is related to growing periods. The result provides a reference for determination of appropriate collection time.

Low Grade Chondrosarcoma Presenting as Progressive Valgus Limb Deformity in a Growing Period / 대한골관절종양학회지

A femoral bone tumor causing a valgus deformity by affecting the growth plate was found. Long intramedullary diaphyseal tumor was separated by septum at the metapysis. Low grade chondrosarcoma was confirmed diagnosed by pathologists. Progressive limb deformity can be a sign of bone tumor in growing period.

Resposta produtiva de reprodutoras pesadas recriadas com diferentes quantidades de ração / Productive results of broiler breeders hens that during the growing period received differents quantities of feed

Na área de produção animal, mais especificamente no caso de matrizes avícolas tipo corte, tem sido dada atenção especial ao melhoramento genético das mesmas. Recomendações quanto ao manejo geral das aves não tem tido a mesma evolução. Existem dúvidas quanto a quantidade ideal de ração a ser fornecida por ave/dia, principalmente durante a recria, para que ela tenha um desenvolvimento corporal adequado e, conseqüentemente, expresse ao máximo o seu potencial produtivo. Este experimento foi conduzido com o objetivo de avaliar parâmetros produtivos de matrizes de corte recriadas com diferentes quantidades de ração. Da 5ª a 20ª semana as aves foram alimentadas com 15% a menos de ração do que recomenda o manual da linhagem (ARBOR ACRES, 1992; T1), 10% a menos (T2), a quantidade padrão (T3) e 10% a mais de ração sobre a quantidade padrão (T4). Os resultados mostram que o peso corporal das aves é diretamente afetado (P<0,05) pela quantidade de ração consumida. Apesar das aves mais pesadas (T3 e T4) terem iniciado a postura mais precocemente, não produziram mais ovos (P>0,05) que as mais leves (T1 e T2), sendo que estas por sua vez, produziram maior número de ovos incubáveis (P<0,05). O peso médio dos ovos não foi afetado pelos tratamentos. Logo, é possível recriar matrizes de corte com 15% a menos de ração sem que a produção das aves seja afetada, e ainda, tendo-se como vantagem a economia de cerca de l340g de ração por ave alojada.

In animal production, particularly in the área of broiler breeders, special attention has been given to the genetic improvement of these birds. General management practices of these birds have not suffered the same development. There are doubts in relation to the ideal quantity of feed to be offered per bird/day, particularly during the growing period, só that the bird may have an adequate corporal development and expresses to the maximum all of the productive potential. This experiment was conducted in order to analyse production parameters of broiler breeders grown with varying quantities of feed. From the 5th to the 20th week of age the birds were fed 15% less ration than that recommended by the breed manual (ARBOR ACRES, 1992; T1), 10% less (T2) the quantity recommended (T3) and 10% more than the recommended quantity. The results show that the body weight of the birds is directly affected by the quantity of feed consumed (P<0.05). Even though the heavier birds (T3 and T4) started laying earlier, they did not produce more eggs than the lighter birds (T1 and T2} (P>0.05) which in turn produced more hatchable eggs than the heavier birds (P<0.05). The average egg weight was not affected by the differents treatments. This shows that boiler breeders can be grown on 15% less feed whitout their production being affected and with the added advantage of saving about 1340g of feed per bird housed.

The Changes in Flexibilities of Rabbits' Tibiae in the Growign Period / 대한정형외과학회잡지

In order to define the changes of mechanical properties of bone tissue in the growing period, 90 rabbits' tibiae were loaded in 3-point bending. Emphasis was given to the accurate measurement of maximum angulation degrees within the limit of elastic deformation. Young's modulus of elasticity increased with increasing body weight, and the increments of bending stiffness were more prominent. In rabbits of low body weights, the tibiae absorbed more energy before fracture occurred and plastic deformation after fracture occurred more frequently. The mean values and standard deviations of the maximum angulation were 9.84±1.33 degree in Group 1 (range of body weight: 800–1200g), 7.55±0.85 degrees in Group 2 (range of BW: 1600–2000g), and 5.90±0.78 degrees in Group 3 (range of BW: 2400–2800g), These data may support that the allowable maximum angular deformity in treatment of fracture should be adjusted according to the increase of body weight-in other words, maturation.
