The present study has been performed to suggest a method to decrease the adverse effects of transportation on chicken meat quality. The groups were prepared as follows; Control group and three groups of treatments (sodium phosphate, sodium bicarbonate and magnesium sulfate). The chicken fed magnesium sulfate showed higher chicken meat quality compared to control and other treatment groups. Also, minor and severe PSE incidence of chicken breast was found at 88% in sodium phosphate group, 24% in sodium bicarbonate group and 56% in magnesium sulfate group. Control group showed 92% higher minor and severe PSE incidence of chicken breast compared to other groups. In control group, the external bruise of chicken showed 32% but 22, 24 and 44% in other treatment groups, respectively. Lightness ($L^*$) of chicken containing sodium phosphate treatment, sodium bicarbonate treatment and magnesium sulfate were 67.05, 66.27 and 65.89, while Lightness ($L^*$) of chicken containing control group was decreased of 67.88. In conclusion, dietary buffer material (sodium phosphate, sodium bicarbonate, magnesium sulfate) under heat stress decreased adverse effects including death, wound or abnormality of chickens.

Purpose: The most common metabolic defect appearing following a gastrectomy is anemia. Two types have been identified: One is related to a deficiency in iron and the other is related to an impairment in vitamin B12 metabolism. The purpose of this study is to evaluate the incidence and treatment of vitamin B12 deficiency after a total gastrectomy. Materials and Methods: Serum vitamin B12 concentrations were measured in 128 patients who had undergone a total gastrectomy. The group with a serum concentration under 200 pg/ml was supplemented at one-month intervals with Actinamide and five-six months later, serum concentrations of the vitamin B12 were rechecked. Results: The group with vitamin B12 under 200 pg/ml was 61 (47.6%) of the 128 patients who had undergone a total gastrectomy. In this group, the cumulative incidences of vitamin B12 deficiency were 7.0, 23.4, 33.6, 39.1, 41.4, and 47.7% at 6 months, 1, 2, 3, 4, and 5 or more years, respectively. The treated group with vitamin B12 under 200 pg/ml had 36 (28.17%) of the 128 patients. The 16 of those cases with vitamin B12 levels of $100{\sim}150\;pg/ml$ were supplemented 5.21 times and the vitamine B12 was elevated to above 650 pg/ml. The other 20 cases with an average of vitamin B12 levels of $150{\sim}200pg/ml$ were supplemented an average of 4.75 times, and the vitamin B12 was elevated to above 780 pg/ml. Conclusion: It is necessary to supplement vitamin B12 even 1 year later after a total gastrectomy. The group with vitamin B12 under 200 pg/ml was supplemented $5{\sim}6$ times at one-month intervals with Actinamide $1,000\;{\mu}g$ IM injections and reached normal levels.

Neuroleptic malignant syndrome(NMS) is an acute, potentially fatal, idiosyncratic reaction to neuroleptic medication. Early recognition and intensive care are crucial. An important issue is whether NMS will recur after initial recovery and subsequent use of neuroleptic medication. The authors presented with a male adolescent who had suffered a bipolar disorder manic episode and been taking clozapine after recovering from MNS. He had been admitted into a psychiatric ward once before and similarly diagnosed. On the second admission, he showed muscle rigidity, autonomic instability, mild fever, severe diaphoresis, and altered mental status on the fourth hospital day following a haloperidol injection. He was diagnosed with NMS, according to the clinical signs and laboratory data. After the use of antipsychotics was discontinued, he was moved to intensive care unit and given dantrolene. His condition began to improve about 48 hours after the onset of NMS. Due to manic behavior, he returned to the psychiatric ward. On the 21 st hospital day, clozapine was administered to counter the manic symptoms. The final dose was 350mg and showed good remission signs without further recurrence of NMS.

The purpose of this study was to find out the Bcl-2 (B-cell leukemia/lymphoma-2), Bax, and caspase-3(cysteine-aspartic proteases-3) protein expression in soleus and EDL muscle according to treadmill exercise intensity in 60 week-old SD rats. The SD rats were randomly divided into four groups (n=10 in each group): control (CON), low intensity exercise (LE), moderate intensity exercise (ME), and high intensity exercise (HE). The exercise was given to the rats for 8 wk, 5 day/wk. The animals underwent treadmill exercise at intensities of 30 min at 8 m/min for the LE group, 15 min at 16 m/min for the ME group, and 9 min at 24 m/min for the HE group. The results were as follows: the expression of Bcl-2 protein was lowest in the HE group and the expression of Bax protein was highest in the HE group. The expression of caspase-3 (cleaved form) protein was observed in the HE group. For the different types of muscle fiber, Bcl-2 protein expression in the soleus muscle was decreased in all groups. Bax protein expression in the soleus muscle was increased in the HE group only. Bcl-2 protein expression in the EDL muscle was decreased in the HE group, and Bax protein expression in the EDL muscle was increased in the ME and HE groups. Consequently, the protein expression related to the aged rats shows a difference according to the intensity of exercise. In addition, caspase-3 protein expression appeared in the HE group; however, in all amounts of intensity, DNA fragmentation was not observed. Therefore, apoptosis on skeletal muscles of aged mice can be intervened with optimal exercise. On the other hand, high intensity exercise can potentially accelerate the apoptosis of muscle fiber in aged rats.

Many of the patients with extensive abrasion need comprehensive restorative treatment. The abrasion is usually caused by attrition, besides of it, there are many reasons for it. The plan of treatment should be started on assessment of the type of attrition and the etiologic analysis. Patient with well-developed masticatory muscle, alveolar process, and high occlusal force and also with little muscle length difference between the stable and the contracted state should be carefully assessed for the vertical dimensional loss and the restoration should be carefully designed. Decrease of tooth length can be compensated by the growth of the alveolar bone height; therefore, consistency of the occlusal vertical dimension is maintained. Accordingly, a careless increase of the vertical dimension can produce muscle fatigue, depressed tooth and pain, and fracture of the restoration. In this case, the patient with multiple tooth abrasion and clenching habit, the edentulous maxillary area is restored with amalgam inserted RPD, and the dentulous area of the maxilla and mandible are treated with fixed restoration accompanying with the increase of vertical dimension. Consequently, we are going to report about the satisfying result in both functional and esthetic aspects.

Myostatin (MSTN), a member of the transforming growth factor (TGF)-beta family, is a potent negative regulator of skeletal muscle growth and maintenance. The MSTN prodomain inhibits MSTN biological activity. The rotifer Brachionus rotundiformis is an excellent primary live feed for fish larvae in aquaculture; however, it is not known whether the rotifer expresses MSTN and the MSTN prodomain along with its activity. The objective of this study was to examine the effects of recombinant MSTN prodomains. Individual cultures of the rotifer B. rotundiformis were carried out to determine the effect of recombinant MSTN prodomains (pMALc2x-poMSTNpro and pMALc2x-sMSTNpro) on the pre-reproductive phase, reproductive phase, post-reproductive phase, offspring, lifespan, fecundity, and male ratio. In addition, a population culture of the rotifer was performed to confirm the effects of pMALc2x-poMSTNpro and pMALc2x-sMSTNpro on population growth. The results showed that the rotifer treated with pMALc2x-pMSTNpro had a reduced pre-reproductive phase at higher concentrations (1, 2, and 4 ${\mu}g/ml$) compared to the non-treated control group. Moreover, the pMALc2xsMSTNpro treated rotifer effectively decreased the pre-reproductive phase at a lower concentration (0.25 ${\mu}g/ml$) compared to the pMALc2x-pMSTNpro treated and control group. Interestingly, pMALc2x-poMSTNpro and pMALc2x-sMSTNpro significantly increased the population of $B.$ $rotundiformis$.

In November 2013, a case of sustained combustion of a female body was encountered in a Korean farming village. The body was almost completely incinerated from the neck to the knees, and other parts of the body, such as the head, arms, lower legs, and feet, were slightly damaged. The most likely external ignition source was the flame from a matchstick. The elderly woman was found incinerated on the floor of the living room, while other objects in the house were largely undamaged except for having a brown oily or greasy coating. Flammable substances were not detected from the woman's intact pieces of clothing and socks, and her muscular tissues did not contain toxic chemicals. The concentration of carboxyhemoglobin in her peripheral blood was 11% and that of ethyl alcohol in her aqueous humor was below 0.010%. An autopsy failed to determine the exact cause of death because of excessive charring.

We investigated the survival rate by water temperature and salinity, physiological rhythm and morphological change of live abalone to get to know optimum water temperature and salinity suitable for long-distance transportation of live abalone. At $8^{\circ}C$ and above, 96-100% of survival rate was shown at all experiment groups. At $6^{\circ}C$, 66% of abalones survived in normal seawater but they showed 0% of survival rate at $30{\pm}0.5psu$ and $26{\pm}0.5psu$ of salinity at the same water temperature. There was no significant difference of oxygen consumption rate for a week between the seawater and $30{\pm}0.5psu$. Also, a positive correlation was shown between salinity and water temperature and the oxygen consumption rate was slightly higher at $30{\pm}0.5psu$ than seawater. Thinned epithelial layers and expansion of lymph sinus were observed less than $30{\pm}0.5psu$ or below $6^{\circ}C$ of temperature. This result shows that the optimum level of water temperature and salinity is considered to be $6-8^{\circ}C$ and more than $30{\pm}0.5psu$ respectively.

In case of treating the functional type of anterior cross bite, removing the cause in early stage prevents from turning to skeletal type, leads to perform normal function, and has improved facial appearance. Functional Regulator III (FR III), one kind of the Functional regulator(FR)s suggested by R$\ddot{o}$lf Fr$\ddot{a}$nkel in 1966, applied to patients with the functional and skeletal anterior crossbite in early mixed, and permanent dentition. This appliance improves unbalanced power condition by blocking abnormal muscle-power effect, so that normal growth can be expected. In this case report, favorable results were obtained by selecting clinical cases of children in their early mixed dentition with functional cross bite. 1. FR IIIs were applied to patients with anterior crossbite for 5~6 months. Anterior crossbite patients were corrected favorably, nevertheless they didn't show any horizontal skeletal-changes by buccal shields. 2. Normal occlusion and esthetic facial contour were achieved from dental movement of maxillary and mandibular anterior teeth while the mandible rotates to posterior and inferior direction.

In diabetics, the frozen shoulder has been difficult to treat. They tend to respond poorly to manipulation. In this report we present the rationale and results of arthroscopic selective capsular release for those patients. Nine patients, who were diabetics, developed frozen shoulders which failed to respond to conservative management. They had persistent pain, stiffness, and limited function. An arthroscopic release was performed by progressively releasing the anterior structures from superior to inferior. Postoperatively physiotherapy was carried out daily to maintain the range of movement. At a follow up of 12 to 37 months the patients were assessed using the American Shoulder Society scheme. In addition, the patients were assessed preoperatively and postoperatively on four criteria: pain, external rotation, abduction and function. We found that the patients were statistically significantly improved in all four categories. Three of the nine patients had no pain, full range of motion compared with the opposite side and full function. There was one poor result of no improvement. The remaining five patients had improved but still had residual abnormalities. We consider arthroscopic release to be an effective treatment for the resistant diabetic frozen shoulder.
