Using isolated rat heart preparations, we observed the protective effe ts of verapamil cardioplegia on ischemic myocardial injury. Isolated rat hearts were subjected to global ischemia at $25^{\circ}C$ Twenty four isolated Sprague Dawley rat hearts underwent 30 minutes of the retrograde nonworking perfusion with Krebs-Henseleit buffer solution followed by $25^{\circ}C$ cardioplegic solution (St. Thomas'Hospital Cardioplegic Solution) for 60 minutes. Before ischemic arrest, rat hearts were treated with cold cardioplegic solution in control group (n=12) and cold cardioplegic solution with verapamil (1 mg/L) in experimental group (n=12). After 60 minutes of ischemia, hemodynamic and biochemical parameters such as heart rate, left ventricular pressure (LVP), + dp/dt max, coronary flow and creatine phosphokinase (CPK) were measured before giving cardioplegia and 30 minutes after reperfusion. Verapamil group exhibited greater recovery of heart rate, LVP, +dpldt max, coronary flow and CPK than control group (p < 0.05).

1. The effects of heat stress (38$^{\circ}C$), cold stress (4$^{\circ}C$) and extreme cold stress (-20$^{\circ}C$) before slaughter on the tenderness and postmortem glycolysis if the excised chicken breast muscle were studied Heat stress significantly (p 0.05) increased the toughness of breast muscle. Though statistically not significant, cold stress also adversely affected the tenderness. The heat-stressed birds showed higher zero hr glycogen higher zero hr pH and significantly (p 0.05) love. ultimate pH then the controls. The cold-stressed birds showed intermediate values in these parameters. Highly significant correlations. were observed between shear value and each of these three parameters. Glycolysis rate ana final moisture content were minor factors which affected the muscle tenderness to a limited extent. The slightly elevated lactate-dehydrogenase and creatine phosphokinase activities in serum and breast muscle of stressed birds failed to account for any variations in tenderness. 2. Chicken breast and thigh muscles were subjected to different environmental temperatures to determine if the phenomenon of cold shortening exists in chicken muscle. For both breast and thigh muscles, minimum shortening was observed in the 4-10$^{\circ}C$t range. Muscles held at 0$^{\circ}C$ showed a slightly higher extent of shortening than at 4$^{\circ}C$; where as muscles held at above 20$^{\circ}C$ showed a severe shortening effect. It was concluded that no apparent cold shortening was detected in chicken muscle except at 0$^{\circ}C$ and even at 0$^{\circ}C$ and even at 0$^{\circ}C$ the extent of shortening was of a small magnitude compared to bovine muscles. Since high temperature induces a much greater shortening, muscle temperature must be lowered to below 20$^{\circ}C$ as early as possible to prevent excessive muse]e shortening.

The activities of serum of serum lactate dehydrogenase (SLDH), serum alkaline phosphatase (SALP), serum creatine phosphokinase (SCPK), and their isozymes were determined in adult male Sprague-Dawley rats acclimated to cold environment $(4\\pm1^\\circC)$ for 36 days. The SLDH activity was significantly higher in the early stage of acclimated period. The steady state of SLDH activity seemed to be reached by the end of acclimated period. Electrophoretic separation of serum of control rat showed three SLDH isozymes. Isozymes SLDH4 and SLDH5 appeared most prominently, whereas only trace of SLDH1 or SLDH2 was found. The increase in SLDH level during acclimation to cold environment is a reflection of an immediate increase in the SLDH1, SLDH2, and SLDH3 type of SLDH isozyme. The acclimation to cold environment increased significantly level of SALP in the early state of acclimated period. SALP activity showed a attaining steady state with the resting level after transient rise. Electrophoretic separation of SALP of control rats showed the SALP1 and SALP2 fractions. The transient rise in SALP activity of rats acclimated to cold environment coincided with a transient rise in SALP1 fraction. Immediately after exposure to cold environment, there was significant elevation in SCPK activity. Value returned to normal after transient rise. A new steady state of SCPK activity seemed to be reached by 36 days. It may be inferred from the above data that thermal compensation appears to result from a change in the activity of an enzyme and that the SLDH, SLDH-isozyme, SALP-isozyme, and SCPK may be involved directly or indirectly in thermoregulation during acclimation to cold environment.

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.

This study was designed to investigate the differences of physiological variables by age group in alcohol-consuming men. The thirty year old-age group had the lowest waist-hip ratio (WHR), right and left cardio-ankle vascular index (R-CAVI and L-CAVI), right and left ankle-brachial index (R-ABI and L-ABI), amylase, high sensitivity C-reactive protein (hs-CRP), and creatine phosphokinase (CPK) levels, and the highest body weight (BW), interleukin-6 (IL-6), right and left intraocular pressure (R-IP and L-IP), hematocrit (Hct), hemoglobin (Hb), erythrocyte, red blood cells distribution width (RDW), alanine aminotransferase (ALT), total cholesterol (TCH), triglyceride (TG), and ferritin levels. The forty year old-age group was the highest in hs CRp and CPK levels, but the lowest in ferritin level. The fifty year old-age group possessed the highest WHR, diastolic blood pressure (DBP), R- and L-ABI, eosinophil, and amylase levels. The sixty year old-age group had the highest R- and L-CAVI, mean corpuscular volume (MCV), ALP, $\gamma$-glutamyltranspeptidase ($\gamma$-GTP), rheumatoid factor (RF), $\alpha$-fetoprotein (AFP) and prostate specific antigen (PSA) levels and the lowest BW, DBP, R-IP, L-IP, Hct, Hb, leukocyte, platelet, RDW, eosinophil, monocyte, ALT, amylase, TG, and CPK levels. These findings indicate that there may be differences of physiological variables depending on age group in alcohol-consuming men. Further studies should be focused on the physiological differences between alcohol-consuming men and women.
