  • Gulbi were made by salting fresh Yellow corvenia (Pseudosciaena manchurica) in three ways; the dry salting method with bay-salt, the dry salting method with purified salt or the abdominal brine injection method with purified salt. Half of the sample was dried by controlling temperature and relative humidity and the other part was dried under the natural condition. The moisture content of the samples were decreased more rapidly by the controlled system than by the natural condition. The lipid content and the iodine values of the muscle and skin of the Gulbi were decreased slowly with laps of drying period. The peroxide values of the sample were increased to its peak after 10 days of drying, and were decreased rapidly thereafter. Both acid values and the thiobarbituric acid values were increased. The deterioration of lipids during Gulbi processing was not notable depending on the salting method, but the natural drying condition affected more severely in their deterioration.

  • The absorption and excretion times of oxolinic acid(OX) used in farms as new aquatic antibiotics commonly were evaluated with determination of the effects of water temperature and feeding to parameters by using the bioassay technique. On the same time, antibacterial activity and the complex formation of oxolinic acid with serum proteins of two different fishes were compared to those oxytetracycline(OTC). With more than 10 times lower MIC values than those of OTC in the strains among 13 analyzed fish pathogens. OX did not show the decresed antibacterial activity by the binding of serum proteins in carp and tilapia. It implies more powerful potential of OX as aquatic medicine OTC. The serum concentration of OX after different administrations the oral, i.m., i.v and dipping methods were compared. The higher beginning concentration in serum and faster excretion times were obserbed in i.m. and dipping methods respectively. In the oral and i.m. administration, peak serum concentration after 24-48 hrs and slow excretion times demonstrated in both methods. These pharmacokinetic characteristics similar at $30^{\circ}C$ and $20^{\circ}C$ water temperature conditions, however, beginning serum concentration of OX in fish dipped in $50mg/\ell$ sol after starvation for 2 wks was appeared lower than those of fed fish. It suggests the importance of biological condition of the gill or skin for absorption of antibiotics after dipping administration.

  • Efficacy of praBiquantel (CesocideB injection) by intramuscular (1.M.) route against cestode infections was evaluated. Total 93 domestic or laboratory animals such as dogs, cats, rats, mice, goats, deers and chickens were used. Animals were infected with Dipylidium caninum, Spirometra sp. , Taenia pisiformis, Taenia taeniaeformis, Hymenolepis nana, Moniegia expanse, Moniexia sp. or Raillietina sp. A single dose of prasiquantel, 6 mg/kg of body weight, was highly effective (97.9%) against cestodes of various kinds disregarding the host species or their intensity of infection. At higher dose above 6 mg/kg, the cure rate was 100%. All the cestodes treated were expelled from the host within 48 hours. The discharged proglottides were damaged severely except Hymenolepis nana and Moniegia expanse. Intramuscular injection of this drug evoked a brief pain response in a dog, but no other side reactions were observed.

  • There are various types of foreign body reactions, such as inflammation, edema, fluid collection, hematoma, infection, abscess and granulomas. There are various imaging findings according to types of foreign bodies and depending on the lapse of time. Therefore, correct diagnosis of a foreign body reaction is difficult and easily confused with soft tissue neoplasm. The MRI is ideal for the detection of foreign bodies regardless of radiolucency or acoustic impedance. It is especially very useful in the evaluation of the surrounding tissue reaction. The authors report a case of a 26-year-old female patient with both forearm swelling due to self-injection of a mixture of powdered tablets and saline. The lesion shows numerous internal T1 and T2 dark signal intensity micro-spots with surrounding fluid collection, which are diagnosed as foreign bodies with surrounding inflammatory changes during an operation.

  • The current study was conducted to investigate the effects of administration of antiserum against adipocyte plasma membrane(APM) proteins into rats on body fat mass. Twenty(20) male adult Sprague-Dawley rats were randomly allocated into either control or antiserum treatment group(10 rats/treatment) and immunized with physiological saline(control group) and polyclonal antiserum (treatment group), respectively, raised in sheep against rat APM proteins(5times, 2day interval). All animals were killed 4weeks after last injection. Intraperitoneal(i.p.) administration of antiserum significantly(P=0.0054 and P=0.0019, respectively) reduced subcutaneous(21.9%) and perirenal + mesentric + epididymic(36.0%) adipose tissue mass in rats of treatment group. Although body weights of antiserum treated rats were decreased during immunization, the rats recovered their body weight after 1 week of treatment. There were no significant changes in the level of blood glucose and in the contents of muscle protein and fat in antiserum treated animals. Current results indicate that polyclonal antibodies against APM proteins could be used to manipulate body fat mass in meat animals as well as laboratory animals. Further studies, however, are necessary for the practical applications of the current results.

  • The experiment was carried out to observe whether the route of administration of allantoic aminiotic fluid obtained from the chicken embryo infected with $B_1$ virus would affect the protectivity of brids against the challenge exposure of a virulent strain of ND virus. Four groups of birds of 30 days of age were immunized intranassally (0.1 $m\ell$), intramuscularly (1.0 $m\ell$), by spray administration (0.00015 $m\ell$/1㎤) or via drinking water(10.0 $m\ell$), with 1 in 100 dilution of th. fluid containing $B_1$ virus titre of 10$\^$8.5/ELD$\_$50/ per $m\ell$ and all the immunized birds, after 15 days of vaccination, were challenged intramuscularly with 1.0$m\ell$ of 10,000 MLD per $m\ell$ of a virulent ND virus. The results obtained are summerized as follows: 1. Good immunity was induced when 1 in 100 dilution of allantoaminiotic fluid with $B_1$ virus titre of 10$\^$8.5/ELD$\_$50/$m\ell$was applied to 30 day old chicks intramuscularly, intranasally and by spray application, but it was not the case when the allantomiotic fluid was diluted to 1 in 1,000. The ID$\_$50/ of birds immunized with 1 in 100 dilution of allantoaminiotic fluid by various routes of administration such as intramuscular Injection, spray application and intranasal instillation were 10$\^$2.8/>10$\^$4.l and/>10$\^$4.2/ 2. The high protectivity against the challenge exposure with a virulent Newcastle disease virus with 10,000 MLD/$m\ell$ were observed when the birds were immunized with a live vaccine of 10$\^$8.5/ ELD$\_$50/$m\ell$ by intramuscular injection, intranasal instillation or spray application, and the rates by different routes of application were 92.62%, 95.33% and 93.75%, respectively. On the contrary, no good immunity was induced in the groups of birds immunized via drinking water with the live vaccine, the rate of protection against the challenge exposure being 47.18%.

  • The search for tumor-avid agents for use in nuclear medicine imaging is an ongoing field of importance. The purpose of this study was to determine the affinity for radio labeled vitamin $B_{12}$ by a wide histologic variety of tumor types in mice. Seventeen different types of tumor were grown subcutaneously in female Balb/C or Balb nu/nu(nude) mice. When the tumors reached about 1 cm in diameter, mice were injected intraperitoneally with $^{57}Co$-vitamin $B_{12}$. Twenty-four hours later, the mice were sacrificed. Organs and tissues were removed, weighed, and activity per mg determined by gamma counter. Values represented cpm/mg tissue that was normalized to 20 grams body weight for each mouse. A wide variety of tumor types showed significant uptake and concentration of $^{57}Co$-vitamin $B_{12}$, as evidenced by tumor:tissue activity ratios. For many tissues of great importance in terms of background(bone, muscle, blood), the tumor:tissue activity ratios of uptake were high. These data strongly suggest that further efforts to evaluate the utility of radio labeled adducts of vitamin $B_{12}$ for clinical use in oncologic imaging are warranted.

  • Purpose: There are a few case reports on asymmetric vocal cord uptake on FDG-PET in patients with unilateral vocal cord paralysis, which could be a potential pitfall in the interpretation of FDG-PET images. We evaluated the metabolic activity of laryngeal muscles of patients with unilateral vocal cord paralysis in comparison to normal controls during both speech and silence. Methods: Eleven patients with unilateral vocal cord palsy (thyroldectomy=7, lung cancer=1, others=3) and 12 normal controls underwent FDG-PET with usual protocol. They were divided into two groups respectively; one group read books aloud for 20 minutes (phonation group) and the other kept silence (non-phonation groups) after FDG injection. Recent neck CT scan were co-registered with FDG-PET to produce PET-CT fusion images to elaborate small laryngeal muscles. Results: In patients with unilateral vocal cord palsy, contralateral non-paralyzed vocal cord showed hypermetabolism mainly on thyroarytenoid muscle, more intensely with phonation group ($SUV=5.88{\pm}2.65$) than with non-phonation group ($SUV=2.30{\pm}0.39$). Normal control subjects showed hypermetabolism ($3.68{\pm}0.96$) in interarytenoid muscle and symmetric mild hypermetabolism in both lateral cricoarytenoid muscles in only phonation group. Conclusion: FDG-PET with fusion images using CT scan in patients with unilateral vocal cord paralysis showed hypermetabolism of contralateral non-paralyzed thyroarytenoid muscle, suggesting compensatory action during phonation. Phonation durung FDG PET study enhanced FDG uptake on different laryngeal muscles between patients with unilateral vocal cord paralysis and normal subjects.

  • 최근 근관 치료 영역에서는 적절한 기계적 근관 성형과 근관 세척으로만 효과적으로 근관 내 미생될의 숫자를 감소시킬 수 있어 다른 약제의 사용은 권장되고 있지 않다. 그럼 에도 불구하고 수종의 근관내 약제는 감염된 근관에서 미생물의 숫자를 줄이고 근관 내용물의 불활성화와 삼출액을 줄이기 위해 사용되고 있다. 그 중 포름 알데하이드를 함유하고 있는 Depulpin$^{(R)}$과 근관 치료학에서 오랫동안 널리 사용되어온 수산화 칼슘을 포함하고 있는 Tempcanal$^{(R)}$과 Vitapex$^{(R)}$ 등에 대한 세포 독성은 충분한 연구가 이루어지지 못한 상태이다. 이에 본 연구에서는 이들 약제가 백서에서의 세포 독성에 미치는 영향에 관하여 고찰하고자 하였다. Sprague-Dawley계 백서 숫놈 20마리를 사용하여, 각각의 쥐는 케타민과 럼푼을 근육내 주사하여 마취하였고, 복부의 피하 부위를 절개한 뒤 3개씩의 Teflon-coating된 매식체를 삽입하였다 매식체 안에는 각각 Tempcanal$^{(R)}$, Vitapex$^{(R)}$, Depulpin$^{(R)}$을 넣고, 백서 20마리를 6개군으로 나누어 매식체 삽입 후 1주 뒤, 4주 뒤에 희생시켜 매식체 주위 조직을 잘라내고 10%포르말린에 고정 후 파라핀에 포매 하였다 미세 절단기로 4$\mu$m로 연속 절단 후, hematoxy-line-eosin염색 후 3명의 관찰자가 광학 현미경으로 관찰하여 염증의 정도를 4단계로 평가한 뒤 Kruskall-Wallis test(P<0.05)로 통계 처리하였다. 그 결과 제 1군Tempcanal$^{(R)}$ 7일후 군), 제 2군(Vitapex$^{(R)}$ 7일후 군), 제 3군(Depulpin$^{(R)}$ 7일후 군) 모두 중등도의 염증도를 보였으나, 세 군간의 통계학적 유의성은 없었다. 그러나, 제 4군(Tempcanal$^{(R)}$ 30일후 군)과, 제 5군(Vitapex$^{(R)}$ 30일후 군)의 경우에서는 약한 염증도를 보여주었으나, 제 6군(Depulpin$^{(R)}$ 30일후 군)은 가장 심한 염증 반응과 함께 조직 괴사의 양상을 보여주었으며, 4, 5군과 6군간에 통계학적 유의성을 보였다. 본 실험 결과, Depulpin$^{(R)}$은 Tempcanal$^{(R)}$와 Vitapex$^{(R)}$에 비해 높은 세포 독성을 보여주공 있으나, 좀 더 많은 임상적 검증이 필요할 것으로 사료된다.

  • Background: Recently, cell transplantation has been extensively investigated to improve heart function in dysfunctional heart. This study was designed to compare the effects of smooth muscle cells (SMC) and heart cells (HC) transplantation in dilated cardiomyopathic hamsters. Material and Method: HC and SMC were isolated from heart and ductus deferens of BIO 53.58 hamsters, and cultured for transplantation. HC and SMC or culture medium were transplanted into the left ventricle of 17 weeks old adult hamsters in HC transplanted (HCTx), SMC transplantation (SMCTX), and control groups (Con) (N = 10 each). Cyclosporine (5 mg/Kg) was administered subcutaneously for HCTx. Sham operated hamsters (N=10) underwent the surgery but did not receive an injection. At 4 weeks after transplantation, heart function was evaluated in all groups using a Langendorff perfusion apparatus. Result: Histology showed severe focal myocardial necrosis in all groups. HCTx and SMCTx formed huge muscle tissue in dilated myocardium. SMCTx and HCTx had better heart function than Con and sham (p<0.01). And SMCTx had better peak systolic pressure (p<0.05) antral developed pressure (p<0.05) than HCTx. But sham and Con did not any statistical make difference. Conclusion: SMCTx and HCTx formed muscle tissue and improved ventricular function in hamsters with dilated cardiomyopathy And SMCTx showed better heart function in peak systolic pressure and developed pressure than HCTx.
