  • This paper presents results from a study of the body composition and sensory characteristics of female weaner goat meat. A completely randomized $3{\times}3{\times}2$ factorial design was used. Factors were genotype (Thai native; TN, 75% TN $\times$ 25% Anglo-Nubian; AN and 50% TN $\times$ 50% AN), feeding {grazing only, low (1.0% BW/d) and high (1.5% BW/d) concentrate supplementation and parasite control (undrenched and drenched)}. It was shown that there was no effect of genotype on body components and dressing percentage. However, TN and 75% TN $\times$ 25% AN kids had significantly (p<0.05) higher muscle to bone ratios (4.20% and 4.20%, respectively) compared with 50% TN $\times$ 50% AN kids (3.88%). Kids on grazing only had significantly (p<0.01) higher muscle percentage (64.12%) than did kids in low (61.30%) and high (60.62%) supplementary feeding program, but there was no significant (p>0.05) difference between low and high supplementary feeding groups. Kids offered supplementary feeding had significantly (p<0.01) higher percentages of total fat, intermuscular fat, pelvic fat and kidney fat than those of grazing only. Kids offered supplementary feeding had significantly (p<0.05) higher muscle to bone ratios and significantly (p<0.01) higher muscle plus fat to bone ratios compared with those of grazing only. This may be due to significantly lower (p<0.01) bone contents (14.95, 14.17 and 16.8% for kids offered low and high supplementary feeding and grazing only, respectively. There was no significant difference in sensory characteristics of goat meat between genotypes or feeding groups.

  • Four-and-a-half LIM-only protein 3 (FHL3) is a member of the LIM protein superfamily and can participate in mediating protein-protein interaction by binding one another through their LIM domains. In this study, the 5'- and 3'- cDNA ends were characterized by RACE (Rapid Amplification of the cDNA Ends) methodology in combination with in silico cloning based on the partial cDNA sequence obtained. Bioinformatics analysis showed FHL3 protein contained four LIM domains and four LIM zinc-binding domains. In silico mapping assigned this gene to the gene cluster MTF1-INPP5B-SF3A3-FHL3-CGI-94 on pig chromosome 6 where several QTL affecting intramuscular fat and eye muscle area had previously been identified. Transcription of the FHL3 gene was detected in spleen, liver, kidney, small intestine, skeletal muscle, fat and stomach, with the greatest expression in skeletal muscle. The A/G polymorphism in exon II was significantly associated with birth weight, average daily gain before weaning, drip loss rate, water holding capacity and intramuscular fat in a Landrace-derived pig population. Together, the present study provided the useful information for further studies to determine the roles of FHL3 gene in the regulation of skeletal muscle cell growth and differentiation in pigs.

  • This study was to determine the effect of exercise on the recovery of dopaminergic neuron loss and muscle atrophy in 6-OHDA-induced hemi Parkinson's disease model. Exercise was loaded twice per day for 30 minutes each time, at 5 days after 6-OHDA lesioning and continued for 16 days using a treadmill. Exercise significantly increased the number of tyrosine hydroxylase positive neuron in the lesioned substantia nigra and the expression level of tyrosine hydroxylase in the striatum compared with the control group. To examine which signaling pathways may be involved in the exercise, the phosphorylation of $GSK3{\beta}$ and ERK were observed in the striatum. In the control group, basal level of $GSK3{\beta}$ phosphorylation was less than in both striatum, but exercise increased it. ERK phosphorylation decreased in the lesioned striatum, but exercise recovered it. These findings suggest that exercise inactivates $GSK3{\beta}$ by phosphorylation which may be involved in the neuroprotective effect of exercise on the 6-OHDA-induced cell death. In the exercise group, weight, and Type I and II fiber cross-sectional area of the contralateral soleus significantly recovered and expression of myosin heavy chain and Akt and ERK phosphorylation significantly increased by exercise. These results suggest that exercise recovers Parkinson's disease induced dopaminergic neuron loss and contralateral soleus muscle atrophy.

  • Purpose: The purpose of this study is to describe the characteristic clinical findings and treatment of suprascapular nerve entrapment by ganglion and to evaluate its results. Materials and Methods: Seven paitents with suprascapular nerve entrapment were evaluated on an average 13 months(range, six months to three years two months) after surgical excision and decompression. There were six males and one female. The mean age at operation was 31 years(range, 23 to 40 years), Suprascapular nerve entrapment were caused by compression of ganglion cyst in suprascapular notch or spinoglenoid notch in all cases. All patients complained of pain located over posterolateral area of the shoulder. Two patients had atrophy of both the supraspinatus and infraspinatus muscles, In four patients, only the infraspinatus muscle was involved. Muscle strength on both forward flexion and external rotation was decreased in two patients. In four patients, only external rotation was decreased. All patients underwent open excision of ganglion cyst and decompression. Results: The most dramatic effect of operation was prompt disappearance of pain in all patients. The average visual analog scale had improved from 7.2 to 0.6 point at the latest follow-up evaluation. An atrophy of the supraspinatus or infraspinatus muscle partially disappeared in four of six patients and muscle strength of forward flexion or abduction improved in all of six patients. The overall result was excellent for five patients and good for two. Conclusion: Surpascapular nerve entrapment by ganglionic cyst had clinically unique symptoms and signs on physical examination. Surgical excision is effective for symptomatic and functional outcomes. We believe that early intervention can be one of treatment modality before an irreversible damage occurs if the ganglion is large enough to compress suprascapular nerve, and to develop severe pain and muscular atrophy.

  • Background: The purpose of this study was to investigate the effects of pulsed-ultrasound intervention and continued-ultrasound on the MVIC (maximal voluntary isometric contraction) and active ROM (range of motion) recovery of before EIMD (exercise-induced muscle damage). Design: Randomized controlled trial. Methods: Thirty subjects who are student in their 20s at a university participated in this study, these subjects were assigned into three groups, a control group (n=10), experiment group I (n=10) and experiment group II (n=10). The subjects in experimental group were intervened by pulsed-ultrasound and continued-ultrasound, while ones on control group weren't by any intervention after induced EIMD. Results: First, In comparison of the MVIC, in the among group comparison, the MVIC of continued-ultrasound group was significantly larger than those of other groups (p<.005). Second, In the among group comparison, the active extension angle of continued-ultrasound group was significantly smaller than those of other groups (p<.005). Third, In the among group comparison, the active flexion angle of continued-ultrasound group was significantly lager than those of other groups (p<.05). Conclusion: The above results revealed that the continued-ultrasound intervention before an exercise had a significantly improve of muscle function after EIMD. Therefore we can consider the continued ultrasound as a considerable intervention method to prevent or reduce an exercise injury.

  • Purpose : It was to compare changes in respiratory function (pulmonary function, inspiratory function) after four weeks of inspiratory muscle strengthening training (diaphragmatic breathing with upper arm exercise, Power-Breathe breathing) for 36 healthy people. Methods : Subjects were randomly assigned to diaphragmatic breathing with upper arm exercise (Group I) and Power-breathe breathing (Group II) was conducted by the protocol for four weeks five times per week. As the main measurement method for comparison between groups For pulmonary function, Forced Vital Capacity (FVC) and Forced Expiratory Volume at One second (FEV1) were used, and for inspiratory function, Maximum Inspiratory Capacity (MIC), Maximum Inspiratory Pressure (MIP), and Maximum Inspiratory Flow Rate (MIFR) were used. Results : In changes in pulmonary function between groups, FVC and FEV1 showed no significant difference, and in inspiratory function changes, MIC showed no significant difference, but in MIP and MIFR, Group B significantly improved over Group A. Conclusion : The progressive resistance training using the Power-breath device applied to the inspiratory muscle did not show a significant difference in the increase in the amount of air in the lungs and chest cage compared to the diaphragmatic breathing training accompanied by the upper arm exercise. However, by increasing the air inflow rate and pressure, it showed a more excellent effect on improving respiratory function.

  • Among 25 consecutive cases having undergone mitral valve surgery between March 1991 and June 1992 in Gill General Hospital, 11 patients[44%] who had undergone mitral valve reconstruction using prosthetic rings is evaluated and presented. Patients` mean age is 43 + 19 years[range:16-72], and they are consisted with 4 males and 7 females. Mitral valve insufficiency is due to degenerative disease in 6 cases[55%] and rheumatic disease in 5 patients[45%]. Carpentier`s functional classification I is 2 cases, II is 6 cases, and III is 2 cases. Surgical techniques include prosthetic ring annuloplasty[11 patients, 100%], chorda shortening[6, 55%], leaflet mobilization[4,36%], new chorda formation[2, 18%], chorda transposition[1, 9%] commissurotomy[3, 27%], and papillary muscle splitting[3, 27%]. Average number of mitral anatomic lesions per patient are 2.7 and we used average 2.8 procedures upon mitral valve apparatus per patient. There were no surgical mortality and no late valve related admission during the mean follow up period of 17 months. The mean functional class[NYHA] is 2.81 preoperatively and improved to 1.10 postoperatively. Doppler echocardiography showed much improvement from grade II MR [1 case], grade III MR [1 case] and 9 cases of grade IV MR to 6 cases of patients showed no MR, only trace MR in 4 cases, and grade I MR was found only in one patient with NYHA functional class II postoperatively. The postoperative mean mitral valve area is $2.10+0.28cm^2$. We conclude that mitral reconstruction is a predictable and stable operation.

  • 본 연구는 II급 및 III급 부정교합자를 대상으로 activator사용에 따른 각 근육의 적응 및 변화양상을 알아보고자 시행되었다. 본 연구의 대상은 성장 발육기에 있는 아동중 II급 부정교합자 15명과 III급 부정교합자 17명으로 기능적 요인을 갖고있는 자로 선정하였고, 연구방법은 전측두근(T.A.), 교근(M.M.), 후측두근(T.P.), 악이복근 전복(D.A.)의 활성도를 알아보고자 $Biopak^{TM}$ program 과 쌍극표면전극을 이용하여 activator 치료 시작시기와 사용후 6-12개월 사이의 두차례에 걸쳐 안정위, 연하시, clenching등 세가지 조건에서 근활성도를 측정하여 비교해본 결과 다음과 같은 결론을 얻었다. II급 및 III급 부정교합자와 정상교합자의 근활성도를 비교한 결과 안정위시와 연하시 유의한 차이를 보이지 않았으나 clenching시 교근과 후측두근에서는 차이를 나타내었다. 치료전 근활성도가 정상보다 작은 군은 유의성 있는 증가를, 큰 군은 유의성 있는 감소를 보이는 등 대부분의 근육이 일정한 경향을 나타내었고, 이러한 경향은 III급 부정교합군에서 전측두근(연하시), 후측두근(clenching시), 악이복근 전복(연하시, clenching시)을 제외하고 모두에서 보였으며 II급 부정교합군에서는 전측두근(연하시), 교근(안정위, 연하시), 후측두근(clenching시)에서만 관찰되었다. 그러나 이러한 경향은 clenching시에서 감소되었다. II급 부정교합군과 III급 부정교합군과의 근활성도 비교에서 안정위시는 III급 부정교합군의 근활성도 증가율이 II급 부정교합군보다 우세했고, 연하시에는 교근을 제외하고 II급 부정교합군이, clenching시에는 역시 II급 부정교합군이 악이복근 전복을 제외하고 우세하게 나타났다.
