1. 도살전의 환경온도(38$^{\circ}C$, 2$0^{\circ}C$, 4$^{\circ}C$, -2$0^{\circ}C$)가 닭 가슴고기의 연도와 근육내 해당작용에 미치는 영향을 연구하였다. 고온구는 현저하게(p＜0.05) 계육의 연도를 저하시켰고 저온구도 다소 연도의 저하를 초래하였다. 고온구는 대조구보다 근육내 glycogen의 함량과 최초 Ph가 높았고 24시간후의 최종 PH는 현저하게 (P＜0.05) 낮았다. 저온구는 대조구와 고온구 사이의 중간수치를 보여주었다. 고기의 절단력(즉 연도)와 근육내 glycogen 함량, 최초 및 최종 근육 산도(PH) 간에는 현저하게 (p＜0.01) 높은 상관관계를 나타냈고 사후 해당속도와 가열처리후의 고기의 수화도 역시 유의한(p＜0.05) 상관관계를 보여 주었다. 근육 혹은 혈청내의 효소(LDH, CPK)의 활력과 고기 연도와는 아무런 상관관계가 없었다. 2. 도살후 가슴고기와 다리고기를 절취하여 각각 다른 보존온도에 방치하여 근섬유의 단축도를 조사하였던 바 4-1$0^{\circ}C$ 사이에서 가장 낮은 단축도를 보여주었다. $0^{\circ}C$에서 보존시 약간의 단축이 있었으나 현저하지 않았고 보존온도가 2$0^{\circ}C$ 이상일 때 온도상승에 따라 비례적으로 단축도의 급격한 증가를 보여주었다. 따라서 계내에서는 저온보다는 고온에서의 근섬유단축이 더 실제적인 중요성을 가지며 도계후 가급적 속히 15$^{\circ}C$이하로 냉각하므로 심한 연도의 저하를 방지할 수 있다.

The purposes of this study is to discuss and analyze the effect on the recovery from cut in sciatic nerve. This study used 9 weeks male rats of Sprague-Dawley family. Rat in groups 4 were treated with pulsed therapeutic ultrasound for 3 minutes. 3 times weekly at 3MHz respectively (intensity; $0.2W/cm^2,\;0.5W/Cm^2,\;10W/cm^2$); rat in group 1 received placebo ultrasound. In addition, changes of serum aspartate amino-transferase(AST) and creatine phosphokinase(CPK) levels were also demonstrated with diameter of individual muscle fasciculate and number of muscle fiber in each of three types of muscles located in gastrocnemius, soles. The results of comparing the changes in groups are as follows; 1. We found out that hypertrophic epineurium was present in sciatic nerve injured ultrasound treatment of groups. 2. In the gastrocnemius morphological investigation of the group I (control group), severe muscle atrophy were observed at the 7th days of the sciatic nerve injury. however, muscle atrophy of the group IV ($1.0W/cm^2$) were slightly recovered at the 14th days after treatment ultrasound. At the 28th days, muscular fibers were formed in polygon and were significantly recovered. 3. C-fos immunoreactive of the group II ($0.2W/cm^2$), III ($0.5W/cm^2$) were remarkably increased at the 1th day after treatment of ultrasound. Group IV were markedly deceased. 4. Brain-Derived Neurotrophic Factor(BDNF) immunoreactive of the group II, III were increased after 7 days of the sciatic nerve injury. Group IV were markedly increased from 14th days to 28th days after treatment of ultrasound. 5. A significant increase of serum AST levels were demonstrated in control group. However, serum AST levels of massage groups were significantly decreased compared to that of control group in followed order ; ($0.2W/cm^2<0.5W/cm^2<1.0W/cm^2$). 6. A significant increase of serum CK levels were demonstrated in control of group. However, serum CK levels of massage groups were significantly decreased compared to that of control group in followed order ; ($0.2W/cm^2<0.5W/cm^2<1.0W/cm^2$). The above results suggest that ultrasound treatment after peripheral nerve injury might reduce noxious stimuli, facilitate nerve recovery and effective in the functional improvement delaying muscle atrophy or degeneration.

Single and 28-day repeated dose toxicity studies of botulimnn toxin type A were carried out in ICR mice and Sprague-Dawley rats, respectively. In the single dose toxicity study, botulinwn toxin was injected intraperitoneally to male and female mice at a single dose of 40, 59, 89 133 and 200 ng/10 ml saline/kg. All animals died from 59 ng/kg group. Some clinical signs, such as decrease in locomotor activity, dyspnea, prone position and ptosis, were observed in most of both sexes from 59 ng/kg group, but no signs were seen in all animals at 40 ng/kg group. The results showed that the median lethal dose of botulinum toxin might be in the range of 40-59 ng/kg in both sexes. In the repeated dose toxicity study, the test material was administered intradermally for 28 days at doses of 0 (vehicle-treated control), 1.25, 2.5, 5.0 and $10.0ng/head/50{\mu}{\ell}$ saline in male and female rats. No test material-related changes were noted in survivals, clinical signs, food and water consumptions and gross finding in any group. Botulinum toxin treatment significantly decreased the body weight gain rate in male of 5.0 ng/head group and over and in female of 10.0 ng/head group compared to vehicle-treated control. One or more relative organ weights (i.e., spleen, thymus, liver and kidney) were increased significantly from 5.0 ng/head group compared to vehicle-treated control in both sexes. Serum biochemistry revealed increases in aspartate aminotransferase (AST), alanine aminotransferase (ALT), creatine phosphokinase, total protein and albumin in male, and increases in AST and ALT and decreases in $K^+$ and $Cl^-$ in female without dose-pendent manners. In the histopathological study, physical stimulation by needle caused slight inflammations of dennis. In addition, botulinum toxin treatment induced denervation of nerve cell and disuse of muscle, resulting in atrophy of skeletal muscle in both sexes from 2.5 ng/head group. When the antibodies to toxin were determined in all animals, a significant increase in serum antibodies was observed from 5.0 ng/head group. The results showed that the NOAEL of botulinum toxin might be 1.25 ng/head for 28-day repeated dose toxicity in rats.

본 연구는 12주간의 저항성운동 유형이 여성 노인의 근손상 지표 및 혈중지질에 미치는 영향을 규명하고자 하였다. 연구대상은 여성노인 30명을 통제집단 10명, 아쿠아로빅운동 집단 10명, 순환운동 집단 10명을 무선으로 배정한 후 주당 3회 1회 운동시 60분을 적용하여 각 집단별 운동을 12주간 실시하였다. Total Cholesterol(TC), Low Density Lipoprotein Cholesterol(LDL-C), High Density Lipoprotein Cholesterol(HDL-C)은 교호작용효과가 나타나지 않았으나, 체중과 체지방량은 교호작용효과가 나타났다. 체중, 체지방량, TC, LDL-C은 통제집단에 비해 수중운동과 순환운동 후 유의한 감소를 나타냈으며, HDL-C은 통제집단에 비해 수중운동과 순환운동 후 유의한 향상을 나타냈다. Triglyceride(TG), Creatine Phosphokinase(CPK), Lactate Dehydrogenase(LDH)는 유의한 차이를 나타내지 못하였다. 이를 통하여 수중운동과 순환운동은 여성노인에게 있어 체중 및 혈중지질 감소와 HDL-C의 증가에 있어 효율적인 운동이라 제시 할 수 있으며 여성노인에게 있어 근감소예방과 개선에 효과적인 운동으로 적용될 수 있을 것이라 사료된다.

Objectives : In the current study, we performed the 13-week repeated oral dose toxicity test and a 4-week recovery test of standardized Cornus officinalis Sieb. et Zucc. and Psoralea corylifolia L. 30 % ethanol extract (SCP) in Sprague-Dawley (SD) rats owing to aims for verifying no observed adverse effect level (NOAEL). Methods : The animal study was performed according to OECD guidelines for the testing of chemicals section 4 health effects test No.408 repeated dose 90-day oral toxicity study in rodents (03 October 2008). In the repeated dose toxicity study, SCP was orally administered to female and male rats at dose levels of 1,000, 2,000, and 4,000 mg/kg/day for 13-week. The control group and high dose (4,000 mg/kg/day) group were then monitored for 4 extra weeks to determine recovery time after the study period. 1) Results : Compared with the control group, there were no treatment-related adverse effects in clinical signs, body weight, hematology, serum biochemistry (Aspartate aminotransferase, Alanine aminotransferase, Alkaline phosphatase, 𝛾-Glutamyl transpeptidase, Blood urea nitrogen, Creatinine, Glucose, Total cholesterol, Total protein, Creatine phosphokinase, Albumin, Total bilirubin, Triglyceride, Inorganic phosphorus, Albumin/Globulin ratio, Calcium ion, Sodium ion, Potassium ion, Chloride ion), necropsy findings and organ weight (Ovary, Adrenal gland, Pituitary, Thymus, Prostate, Testis, Epididymis, Spleen, Kidney, Heart, Lung, Brain, Liver) at any dose tested. Conclusions : Taken together, these results suggest that the NOAEL of SCP in both genders was considered as over 4,000 mg/kg. Results from this study provide scientific evidence for the safety of SCP.
