We developed a dietary supplement using natural herbs and nutrients for the growth and exercise performance improvement. It called 50-22 supplement containing distilled extracts of natural herbs to remove bitterness and the addition of Vitamin B1, B6, Ca and xylitol. We investigated on the effect of 10-22 supplementation on the maximal exercise performance, IGF-1 (insulin like growth factor-1) concentration and antioxidant activity in SD rat model. In result, JR-22 supplement group was better than control group about 10％ in exercise performance test and increased about 63％ of IGF-1 concentration in blood. In addition, the oxidative damage induced by exercise was reduced by JR-22 supplementation. Therefore, we suggested that 50-22 supplementation enhanced effectively exercise performance and IGF-1 concentration and reduced to oxidative stress in muscles. Also, we analysed biochemical factors in blood for the safety of JR-22 supplement. We known that there is no change of blood lactic acid, ammonia, inorganic phosphorous ion and creatine kinase activity. (Korean J Community Nutrition 8(3) : 349∼355, 2003)

The changes of serum creatine phosphokinase [CPK], serum lactic dehydrogenase [LDH], serum glutamic oxaloacetic transaminase [GOT] and serum glutamic pyruvic transaminase [GPT] were studied in a total of 82 cases who underwent open heart operation under the cardiopulmonary bypass at the Department of Thoracic and Cardiovascular Surgery, Chungnam National University Hospital. The results were as follows 1. The average values of CPK and COT after the operation were reached to the maximal values on the first postoperative day, which were returned to the normal range until the fifth postoperative day. The average values of LDH and CPT after the operation were reached to the maximal values on the first and second postoperative day respectively, which were significantly increased until the seventh postoperative day. 2. In the relationship of the serum enzymes and duration of the extracorporeal circulation, the values on the group over 90 minute of the extracorporeal circulation were more increased than on the group below 90 minute of the extracorporeal circulation. 3. In the relationship of the changes of the serum enzymes and congenital heart diseases and acquired heart diseases, there were no significantly differences in the values between the two groups.

This experiment was carried out under the postulation that activation of an intracellular calcium-calmodulin complex may play an important role in myocardial injury induced by ischemia and reperfusion. Trifluoperazine[TFP], a calmodulin antagonist, was added to the potassium cardioplegic solution and used just before ischemia, and its protective effect from ischemic injury was investigated, using Langendorff rat heart model. TFP group had better post-ischemic functional recovery and lower post-ischemic contracture after 30 minutes of normothermic ischemia. Creatine kinase leakage was also decreased in TFP group but there was no statistical difference between control group and TFP group. We concluded that TFP has some protective effect from myocardial ischemic injury and its effect might be due to prevention of activation of intracellular calcium-calmodulin complex.

The distal myopathies(DM) are clinically defined as inherited or sporadic primary muscle disorders characterized by progressive muscular weakness and atrophy beginning in the hands or feet and pathologically by myopathic changes in skeletal muscles. The pathologic changes are somewhat similar to those seen in chronic muscular dystrophy, but necrotic and regenerative processes are less prominent and creatine kinase levels are either normal or only mildly elevated. The most representative diseases are dominantly inherited Welander distal myopathy and tibial muscular dystrophy, and the recessively inherited distal myopathy with rimmed vacuoles and distal muscular dystrophy(Miyoshi myopathy). At present, further study is necessary to determine why rimmed vacuoles are so common in the DM, and what role they play in the pathogenesis of muscle fiber atrophy and loss, predominantly in the distal portions of the extremities.

A 57-year-old man presented with weakness in both legs upon awakening after drinking. Magnetic resonance imaging (MRI) of the lumbar spine did not reveal any intraspinal abnormalities but MRI of the pelvis revealed lesions with abnormal intensities with heterogeneous contrast enhancement in both gluteal muscles. Serum creatine phosphokinase was markedly elevated. A diagnosis of lumbosacral plexopathy, complicating rhabdomyolysis was made. With supportive care he recovered well but mild weakness of the right ankle remained at 6 month-follow-up. Pelvic MRI is a helpful diagnostic tool in localizing rhabdomyolysis. Lumbosacral plexopathy should be included in the differential diagnosis of the such cases, presenting with sudden weakness of legs.

Using 1H magnetic resonance spectroscopy (MRS), we quantitatively evaluated correlation representing linear relationship between the metabolite peak area ratios associated with poor shimming conditions. The inadequate shimming due to linear shim offsets directly affected overall MR spectral quality as well as peak area for each metabolite. Three major peaks such as N-acetylaspartate (NAA), creatine (Cr,) choline (Cho) were used as a reference for data analysis. Despite considerable variations of metabolite peak area, a significant correlation between the metabolite peak area ratios relative to Cr was established while the correlation between the peak area ratios relative to Cho and NAA was not. The present study suggested that metabolite peak area ratios based on the metabolite of Cr could be an acceptable quantification method even under the poor shimming in clinical MRS examination.

An eight-month old female mixed breed dog was presented to the at Gyeongsang National University Animal Hospital, for tarsocrural arthrodesis. Previously the dog had been presented to a local animal clinic. Orthopedic and blood examinations were conducted. There was absent response of conscious proprioception on the right tarsocrural articulation. The dog stood knuckled onto the digits and had hock dropped but showed normal values in WBC, RBC, Hb, PCV, BUN, creatine, glucose, cholesterol, AST and ALT analyses. The dog was anesthetized and prepared for aseptic surgery. Steinmann pin and Joshi external fixators were applied(bilaterally). 11 weeks after the operation, the external fixators were removed from the bones. The hock dropped was well stabilized, but mild knuckling of distal metatarsopharangeal joint was remained.

This study was undertaken to investigate whether adenosine administered during cardioplegic arrest could enhance myocardial protection and improve recovery of function after ischemia. Isolated Langendorff-perfused rat hearts were subjected to 40 minutes of normothermic [37oC] ischemia. Control hearts [n=10] received modified St. Thomas’ cardioplegic solution, and the remaining hearts received modified St. Thomas’ cardioplegic solution with either 20 \ulcornerM [n=10], 200 \ulcornerM [n=10] adenosine. After ischemia of 40 minutes and 30 minutes of reperfusion, left ventricular contractility was superior in all groups of adenosine-treated hearts compared with control hearts. Furthermore, there was a significant incremental increase in functional recovery with increasing dose of adenosine. Post-ischemic diastolic stiffness was significantly better in all adenosine groups compared with controls. No differences were noted in coronary flow or myocardial water content between adenosine-treated and control hearts. These data demonstrate that adenosine administered in these concentrations provides myocardial protection, preservation of myocardial ATP and creatine phosphokinase and improved post-ischemic functional hemodynamic recovery after normothermic ischemia, presumably metabolically by reducing depletion of adenosine triphosphate, inducing rapid cardiac arrest and enabling improved post-ischemic recovery.
