Facial deformity after nerve injury changes ones' social life. We experienced a few patients with healthy early recovery of muscle contraction after the operation with soft tissue wraparound splint. Under general anesthesia, exploration to find as many injured nerve stumps with ${\times}2.5$ loopes was undertaken at first. Interfascicular repair was done with minimal tension by 10-0 nylon under a microscope, and the suture site was sealed by approximating the surrounding fat flaps. This conjoined adipose tissue flap was a splint as a wraparound environment to reduce the tension in the coaptation site, and to increase the relative concentration of releasing neurotrophic factors by surrounding it. A 45-year-old man fell down in a drunken state and had deep laceration by broken flowerpot fragments with facial muscle weakness on the right cheek. His injured mandibular branches of the facial nerve were found. A 31-year-old female suffered from motionlessnesss of frontalis muscle after a traffic accident. She had four frontal branches injured. The man had his cheek with motion after seven days, and the woman two months after the operation. The nerve conduction test of the woman showed normalized values. Facial nerve repair surrounded by adipose tissue wraparound splint can make the recovery time relatively short.

1. The human body is the unification related to the powerful fascial network, I think. 2. Myofascial not only prevent and support the human body structure curdling but also keep the physical balance by dispersing traumatization properly. 3. Myofascial restriction will be developed into muscle deficiency and cause pains without releasing the muscle tension and the spasm. 4. Myofascial restriction affect and change the physical posture by losing the muscle elasticity and flexibility and by losing muscle supporting ability from gravitation. 5. The partial myofascial restriction affect the muscle and the adjoining joint supporting gravitation and cause the unbalance of the entire body.

The nonapeptide bradykinin has been shown to exhibit an array of biological activities including relaxation/contraction of various smooth muscles. In order to investigate the effects of bradykinin on the contractility and the electrical activity of antral circular muscle of guinea-pig stomach, the isometric contraction and membrane potential were recorded. Also, using standard patch clamp technique, the $Ca^{2+}-activated$ K currents were recorded to observe the change in cytosolic $Ca^{2+}$ concentration. $0.4 {\mu}M$ bradykinin induced a triphasic contractile response (transient contraction-transient relaxation-sustained contraction) and this response was unaffected by pretreatment with neural blockers (tetrodotoxin, atropine and guanethidine) or with apamin. Bradykinin induced hyperpolarization of resting membrane potential and enhanced the amplitude of slow waves and spike potentials. The enhancement of spike potentials was blocked by neural blockers. Both the bradykinin-induced contractions and changes in membrane potential were reversed by the selective $B_2$-receptor antagonist $(N{\alpha}-adamantaneacetyl-_{D}-Arg-[Hyp, Thy,_{D}-Phe]-bradykinin)$. In whole-cell patch clamp experiment, we held the membrane potential at -20 mV and spontaneous and transient changes of Ca-activated K currents were recorded. Bradykinin induced a large transient outward current, consistent with a calcium-releasing action of bradykinin front the intracellular calcium pool, because such change was blocked by pretreatment with caffeine. Bradykinin-induced contraction was also blocked by pretreatment with caffeine. From these results, it is suggested that bradykinin induces a calciumrelease and contraction through the $B_{2}$ receptor of guinea-pig gastric smooth muscle. Enhancement of slow wave activity is an indirect action of bradykinin through enteric nerve cells embedded in muscle strip.

The purpose of this study was myokine product and role with physical activity and literature review. There is accumulating epidemiological evidence that a physically active life plays an independent role in the protection against type 2 diabetes, cardiovascular disease, colon cancer, dementia and even depression. And myokine has been regarded an important factor of exercise training and brain growth factor for the prevention of Alzheimier's disease. During exercise the release of anti-inflammatory myokine from contracting muscle controled the metabolic response, and IL-4, IL-6, IL-7, IL-10, and IL-15 controled muscle hypertrophy, myogenesis and angiogenenesis. IL-6 promoted the lipid metabolism through AMPK activation. IL-1Ra, IL-10 and sTNF-R inhibited $TNF-{\alpha}$ as the pro-inflammatory cytokine. IL-15 increased the releasing volume from contracting muscle, and promoted the anabolic factor of muscle growth. IL-7 and IL-8 activated the angiogenesis through the more activation of C-X-C receptor signal transmission.

The current study was carried out to investigate the impact of extraction conditions on the free amino acid level and type in beef longissimus muscle. The sample blocks were chiller aged for 1 d and 7 d at $4^{\circ}C$. There are three homogenization speeds (11,000, 19,000 and 24,000 rpm) for bigger and two speeds (11,000 and 13,000 rpm) for smaller homogenizer's dispersing tools were used for evaluation. Results showed that chiller ageing greatly (p<0.05) increased extractable free amino acids, except cystine. Homogenization with the bigger dispersing tool at 24,000 rpm resulted in the highest free amino acid levels for both 1 and 7 d samples. Significant differences (p<0.05) in the mean values of most amino acids due to the effect of speed and interactions between ageing times. However, the speed effect and interaction between ageing with homogenization speed were not significant (p>0.05) for most of the amino acids except valine and isoleucine when using the smaller dispensing tools. The current data indicated that a standardized method for free amino acid types and levels of aged beef samples. In addition, the results also suggested that utilization of a big dispensing tool at high homogenization speed is a better condition for releasing free amino acid contents in beef samples.

It has been reported by some authors that caudal block with local anesthetic and steroid is the most effective therapeutic modality for piriformis syndrome; and the incidence ratio of female to male being 6 to 1. We treated 89 patients with piriformis syndrome in 1995. From those clinical experiences and anatomical studies we heave arrived at several conclusions different from other authors. Our results indicate the following: 1) Piriformis syndrome does not provoke lower back pain. 2) Our rate of incidence showed a very different profile as results showed a female to male ratio of 33:56. 3) Releasing the compressed nerves(gluteal, sciatic) with spasmolytic treatment on the piriformis muscle itself is thought to be the only therapeutic modality for piriformis syndrome.

Even though back pain therapy has greatly improved as spinal bio-mechanics is introduced, many patients still have difficulties due to low back pain. At the initial therapeutic stage, the aim of rehabilitation therapy for low back pain is pain control, but, at the later therapeutic stage, the prime aims are to reduce the late complication and to prevent the recurrence of low back pain. Accurate diagnosis should be a first step before any therapy is planned. Thus, accurate physical, neurologic, E.M.G. and radiologic tests are required to give prescription for therapeutic exercise to the patients. In addition to this, the roles of theraphists and therapeutic exercise should be re-evaluated after the therapeutic exercise is performed. Fist of all, the most important things are to educate the patients to understand the low back pain and to let the patients join the therapeutical planning. 1. Bed rest and muscle relaxing exercise for releasing the muscle tention are required for the treatment of acute low back pain. An active exercise is recommended rather than a passive exercise. If the therapeutic exercise depravate the low back pain, the exercise should be immediately terminated and the therapeutical exercise should be replanned. 2. For the treatment of the chronic back pain, stretching exercise and para-spinal muscle strengthening exercise should be performed steadily and actively to prevent the recurrence of low back pain and the low back injury due to minor damage. The patients should be educated to do proper exercise and to maintain good posture in everyday life. 3. As the low back pain is released and the body function is recovered, control of whole body function is necessary. Swiming, bicycling and walking for $30\sim40$ minutes a day and $3\sim4$ days a week are recommended. Other exercise could be recommended depending on the patients condition.

The objective of this study was to analyze the kinematic and kinetic characteristics of two horticultural activities: seed sowing and planting plant. Thirty-one male university students (aged $26.2{\pm}2.0years$) participated in this study. Kinematic factors (movement times, peak velocity, joint angles, and grasp patterns) were assessed using a three-dimensional motion analysis system while the subjects performed the horticultural activities. Kinetic factors (muscle activation of eight upper-limb muscles: the anterior deltoid, serratus anterior, upper trapezius, infraspinatus, latissimus dorsi, biceps brachii, brachioradialis, and flexor carpi radialis) were assessed using surface electromyography. The acts of seed sowing and planting plant were comprised of five tasks which included six types of phases: reaching, grasping, back transporting, forward transporting, watering, and releasing. The movement times, peak velocity, joint angles, and grasp patterns were significantly different across the tasks involved in the horticultural activities. All eight muscles of the upper limbs were utilized during the horticultural activities, and the muscle activation of the serratus anterior was the highest compared to that of the other muscles tested. The kinematic and kinetic characteristics of these horticultural activities showed similar characteristics to reaching and grasping rehabilitation training and daily living activities. The present study provides reference data for common horticultural activities using a kinematic and kinetic analysis.

Nine biochemical characteristics of female Oncorhynchus keta subpopulations that migrate to three streams (Namdaechun, Myeongpachun, Oshipchun) in Gangwon, Korea, were evaluated during November 2006: aspartate aminotransferase, alanine aminotransferase, creatine kinase, triglyceride, cholesterol, glucose, hemoglobin, and urea in the blood and RNA/DNA in muscle. The three subpopulations were identical morphologically, but differed in their biochemical characteristics. The RNA/DNA ratio could be useful for distinguishing the subpopulations. RNA/DNA ratios of the Namdaechun and the Myeongpachun and Oshipchun subpopulations were $3.52{\pm}0.7$ and $2.9{\pm}0.7$ and $2.4{\pm}0.8$, respectively. The difference was statistically significant (P<0.05). By contrast, the blood parameters were somewhat ambiguous.

Fine structures of the testis and vas deferens in the fall-web worm, Hyphantria cunea Drury, are studied with electron microscope. Adult worms have single testis close to the midlines of the abdomen. Testis is composed of 4 follicles which are incompletly separated from each other and bounded together by a peritoneal sheath. The peritoneal sheath consisted of outer cuticular layer and two kinds of inner layers, in which glycogen particles are dispersed commonly. These two layers are divided by the morphology of cytoplasmic granules. Follicular epithelium forming the wall of the follicles have melanin pigment granules, and trachea or tracheoles are extended through this epithelium. In the cysts of adult testis, matured spermatozoa are grouped together in bundles and after releasing the sperm bundles to the vas deferens, lamellar shaped lysosomes appeared in the cytoplasms of the cyst cells. The number of spermatozoa per cyst is exactly 256 ($2^8$), this number is characteristics of the Lepidoperan species. Vas deferens is a tube with a fairly thick bounding epithelium, a basement membrane and a layer of circular muscle outside it. At the apical portion of the epithelial cells, microvilli are well developed. And in the cytoplasms of these cells, numerous excretory granules are observed.
