장인호,Jang, In Ho 대한수의학회 1978 大韓獸醫學會誌 Vol.18 No.1

In order to detect the clinical effect of combelen which is used for sedation of domestic animals, 10 heads of clinically healthy Korean native goats were used in this study. They were divided into two groups; one is dose level of 1ml per 10 kg of body weight with 1% combelen and the other is dose level of 3 ml. Clinical observations and changes in blood components after administration of combelen were made. 1. There was no adverse effect due to combelen, but sedative effect was insufficient. 2. During sedative period the changes in heart rate and respiratory rate showed noticeable change, and body temperature was slightly decreased. 3. In ECG recordings, except for slight changes in T wave, significant change was not observed. 4. Erythrocytes, leukocytes, hemoglobin concentration and packed cell volume showed tendency to decrease during the period of sedation. 5. SGOT activity showed a remarkable increase and BUN showed a great decrease 24 hours after administration in the group of 3ml/10kg. Blood glucose level increased during the period of sedation in both groups.

장인호,최외호,Jang, In Ho,Choi, We Ho 대한토목학회 1989 대한토목학회논문집 Vol.9 No.2

등매개(等媒介) 요소(要素)를 사용(使用)하는 유한요소법(有限要素法)을 적용(適用)하여 직선상자항교(直線箱子桁橋) 강성해석(强性解析)을 수행(遂行)하였다. 이 방법(方法)의 유용성(有用性)과 정확성(正確性)을 보이기 위하여 하나의 연속상자형을 예로 들어 해석하였다. 여기서 구한 처짐과 종방향응력들은 다른 방법으로 구한 결과와 잘 일치함을 알 수 있었다. 본 방법은 임의의 경제조건과 하중을 받는 상자형을 해석하는데 효율적인 방법이며, 설계 해석에 직접 사용될 수 있는 실용적인 방법이다. The finite element utilizing isoparametric plate element is applied for the elastic analysis of straight box girder bridges. A continuous box girder is analyzed as an example to verify the validity and accuracy of this method. It is indicated that the deflections and longitudinal stresses obtained by this method agree well with those from the orther methods. This theory may, therefore, be directly used as an efficient tool to analyze and design box girder bridges subjected to arbitrary loading and boundary conditions.

장혜숙,장인호,Chang, Hye-sook,Jang, In-ho 대한수의학회 1998 大韓獸醫學會誌 Vol.38 No.2

This study was conducted to compare the anesthetic effects of intravenous tiletamine-zolazepam(TZ, 7mg/kg TZ), tiletamine-zolazepam-xylazine(TZX, 7mg/kg TZ and 1.1mg/kg X) and ketamine-xylazine(KX, 10mg/kg K and 1.1mg/kg X). Fifteen mixed-breed healthy dogs($3.5{\pm}1.0kg$) were randomly assigned to the three treatment groups(TZ, TZX, KX) with 5 dogs in each group. The mean surgical anesthesia time was $25.6{\pm}4.2$, $62.6{\pm}6.2$ and $21.0{\pm}3.7$ min in TZ-, TZX- and KX-anesthetized dogs, respectively. The duration of the loss of response to toe-web needle prick and to visceral pain was significantly increased in the TZX group with $40.0{\pm}15.8$ min and $44.0{\pm}5.5$ min, respectively(p<0.01). Heart rate decreased significantly below baseline in TZX and KX groups(p<0.05, p<0.01) whereas it increased above baseline in TZ group. Respiratory rate remained unchanged or increased above baseline in TZ group, but decreased significantly from 10 to 30 min in TZX(p<0.01, p<0.05) and at 10 min in KX group(p<0.05). Body temperature decreased significantly below baseline in all three groups(p<0.01, p<0.05). Hematologic(PCV, RBC, WBC) and serum chemistry values(GOT, GPT, BUN, creatinine, total protein, glucose) were monitored before anesthesia, after recovery from anesthesia and 1, 3 and 7 days postanesthesia. All hematologic values remained generally within normal ranges, and GOT, GPT, BUN, creatinine and total protein values were within normal ranges during the period. Glucose values for TZX and KX groups increased greatly after recovery from anesthesia. We conclude that tiletamine-zolazepam-xylazine provides effective surgical anesthesia in dogs and in many cases may be preferable to conventional ketamine-xylazine regimen.

The incidence of cysts in the respective ovaries, the left ovary was cystic in 23.5% of the cases, the right one in 41.2% and both ovaries in 35.3%. 4. According to the histological findings of cystic ovaries, follicular cysts were 88.2% and luteal cysts 11.8%.

Enterotoxigenic Bacteroides fragilis에 의한 질환과 검출

권선영 ( Sun Yeong Gwon ),장인호 ( In Ho Jang ),이기종 ( Ki Jong Rhee ) 대한임상검사과학회 2015 대한임상검사과학회지(KJCLS) Vol.47 No.4

정상인에서 장내세균은 숙주의 면역이나 영양 흡수를 돕지만, 때로는 기회감염균으로서 그들을 위협하기도 한다. 그 중 절대 혐기성 세균인 Bacteroides fragilis는 분비되는 장독소(enterotoxin)인 Bacteroides fragilis toxin (BFT)의 유무에 따라 nonenterotoxigenic B. fragilis (NTBF)와 enterotoxigenic B. fragilis (ETBF)로 나뉜다. ETBF는 가축 및 사람에서 설사 질환 및 대장 질환을 유발한다 그러나 때때로 ETBF를 가지고 있으나 증상이 없는 사람도 존재한다. ETBF는 염증성 설사 질환, 여행자 설사 환자의 대변에서 검출되어 주목 받고 있다. 또한, 몇몇 연구를 통해 inflammatory bowel disease (IBD)나 대장염 및 대장암 환자에서 ETBF가 증가한다는 것이 밝혀졌다. 일반 C57BL/6 마우스 및 germ-free 마우스, multiple intestinal neoplasia (Min) 마우스, 토끼, Mongolian gerbil 등 여러 동물 모델에서 ETBF가 IBD나 대장염, 대장암을 유발 또는 촉진한다는 것이 발표되었다. ETBF의 유일한 병원성 인자인 BFT는 E-cadherin의 분절을 유도하여 장상피세포의 투과성을 높인다. 이어서 .-catenin 신호전달계가 활성화하여 장상피세포의 증식이 증가한다. 또한 ETBF의 감염은 일반 마우스에서 급성이나 만성의 대장염을 일으키고 Min 마우스에서 종양 형성을 촉진한다. 이는 Stat3에 의존한 TH17 면역반응의 활성화를 통해 일어난다. 현재 ETBF의 검출 방법에는 크게 BFT toxin assay와 몇 가지 PCR 방법이 있다. 최근 real-time PCR과 같은 분자진단학적 기법의 발달로 일반적인 PCR보다 더 정확한 ETBF의 검출이 가능하게 되었다. 이것을 이용하여 앞으로 실제 임상에서 ETBF와 대장염 및 대장암의 발달 관계에 대한 심도 깊은 연구가 이뤄질 것으로 본다. These commensal intestinal bacteria can enhance the immune system and aid in nutrient absorption but can also act as opportunistic pathogens. Among these intestinal bacteria, the anaerobic Bacteroides fragilis are divided into enterotoxigenic B. fragilis (ETBF) which secrete the B. fragilis toxin (BFT) and non-enterotoxigenic B. fragilis (NTBF) which do not secrete BFT. ETBF can cause diarrhea and colitis in both humans and livestock but can also be found in asymptomatic individuals. ETBF is predominantly found in patients with inflammatory diarrheal diseases and traveller…s diarrhea. Several clinical studies have also reported an increased prevalence of ETBF in human patients with inflammatory bowel disease (IBD), colitis and colorectal cancer. In small animal models (C57BL/6 wild-type mice, germ-free mice, multiple intestinal neoplasia (Min) mice, rabbits and Mongolian gerbils), ETBF have been found to initiate and/or aggravate IBD, colitis and colorectal cancer. BFT induces E-cadherin cleavage in intestinal epithelial cells resulting in loss of epithelial cell integrity. Subsequent activation of the 꺬-catenin pathway leads to increased cellular proliferation. In addition, ETBF causes acute and chronic colitis in wild-type mice as well as enhances tumorigenesis in Min mice via activation of the Stat3/Th17 pathway. Currently, ETBF can be detected using a BFT toxin bioassay and by PCR. Advances in molecular biological techniques such as real-time PCR have allowed both researchers as well as clinicians to rapidly detect ETBF in clinical samples. The emergence of more sensitive techniques will likely advance molecular insight into the role of ETBF in colitis and cancer.

The environmental pollution by heavy metals has become a significant hygenic problem. Recently it is said the garlic supplementation in diet have protective effect on the heavy metal accumulation in tissue of rat by a researcher. In this study two experiments were undertaken. Firstly, dogs were fed diet supplemented with cadmium of cadmium plus 7% of raw garlic for 50 days. on the 50th day of experiment all dogs were euthanasied and the cadmium content of various tissue were measured by atomic absorption spectrophotometeric method. Secondly, in order to find out the toxic effect of garlic dogs were fed diet supplemented with 7% of raw garlic for 50 days and hematological or hematochemical observations were undertaken at 10 day intervals. The results obtained from these experiments were summarized as follows; 1. In dogs treated with cadmium and cadmium plus garlic cadmium was accumulated in renal cortex, liver, and muscle. However the concentrations of cadmium showed no significant between the two group. 2. In dogs fed diets supplemented with 7% of raw garlic significant decrease of erythrocyte count, packed cell volume and hemoglobin content and significant increase of Heinz body erythrocyte and reticulocyte count were recognized. 3. The garlic-treated dogs and control dogs had normal asparate aminotransferase, alanine aminotransferase, alkaline phosphotase, blood urea nitrogen value. The value showed no significant difference between the two group. 4. From these results it may be concluded that the garlic have protective effect for cadmium accmulation in tissue and excess garlic in diet could induce hemolytic anemia in dogs.

본 실험은 carboxymethyl chitosan(CMC)이 복강유착에 미치는 효과를 밝히고자 수행하였다. 총 44마리의 rat를 유착유도후 아무런 처치하지 않은 대조군과 각각 1, 2, 3% CMC 용액 3ml로 처치한 3개 실험군 등 총 4군으로 나누었다. 유착은 회장의 장간막 반대측 장막부위를 노출시켜 수술도로 $0.5{\times}1cm$ 크기로 긁어 점상출혈을 유도하고, 우측벽측복막을 $0.5{\times}1cm$ 간격으로 창상을 유도한 후 두 창상을 봉합하였다. 2주후 halothane에 의한 안락사 후 유착정도를 computerized tensiometer로 측정하였다. 유착부 분리에 필요한 장력(Newton)은 대조군이 평균 $2.48{\pm}0.88$이었으며, 1% CMC 처치군은 $1.86{\pm}0.56$, 2% CMC 처치군은 $1.75{\pm}0.71$, 3% CMC 처치군은 평균 $1.55{\pm}0.60$로 3% CMC 처치군에서 유의적인 감소(p<0.01)가 나타났다. 이상의 결과로 미루어 rat에서 복강수술후 CMC의 복강내 투여는 복강장기 유착방지에 효과적이라고 사료된다. The aim of this study was to determine the effectiveness of carboxymethyl chitosan(CMC) solution on preventing intraperitoneal adhesions. In this study, 44 rats were divided into four groups ; an untreated control group and three experimental groups that were treated with 3 ml of 1, 2 or 3% CMC solution, respectively. The anti-mesenteric serosa of the ileum was exteriorized and then abraded in a standard manner by scraping with a scalpel blade to create homogenous petechial hemorrhagic surface over a $0.5{\times}1cm$ area. The adhesions were blindly assessed 2 weeks later by using a computerized tensiometer. The mean tensile strength(Newton) of formed adhesions was $2.48{\pm}0.88$ in control group, $1.86{\pm}0.56$ in the 1% CMC-treated group, $1.75{\pm}0.71$ in the 2% CMC-treated group and $1.55{\pm}0.60$ in the 3% CMC-treated group. The most favorable prevention against adhesion was achieved in the 3% CMC-treated group(p<0.01). We could conclude that CMC was effective on preventing the formation of postoperative small intestinal adhesions in the rat.

한국재래산양(韓國在來山羊)에 있어서 Prostaglandin $F_{2{\alpha}}$의 투여(投與)가 난소(卵巢) 및 뇌하수체(腦下垂體) Hormone의 함량(含量)에 미치는 영향(影響)

재래산양(在來山羊)에 있어서 prostaglandin $F_{2{\alpha}}$의 투여(投與)가 황체퇴행(黃體退行)시에 야기되는 호르몬 함량의 변화(變化)를 구명(究明)하기 위하여 발정주기의 10일에 $PGF_{2{\alpha}}$(Lutalyse) 5mg을 3시간 간격으로 2회 주사(注射)한 다음 경시적(經時的)으로 혈중(血中) 난소(卵巢) 및 뇌하수체(腦下垂體) hormone의 함량을 조사하였다. 본 연구에서 얻어진 결과(結果)를 요약(要約)하면 다음과 같다. 재래산양(在來山羊)에 있어서 발정주기(發情週期)의 10일에 $PGF_{2{\alpha}}$를 주사한 결과 혈중(血中) progesterone의 평균농도는 주사직전에 $4.15{\pm}1.8ng/ml$였으며 주사후(注射後) 3시간에 $2.52{\pm}1.2ng/ml$로 약 60% 감소(減少)하였으며 12시간에는 $0.81{\pm}0.3ng/ml$로 감소(減少)하여 72시간까지 1.02ng/ml 이하로 감소(減少)하였다. 혈중(血中) estradiol-$17{\beta}$ 함량은 $PGF_{2{\alpha}}$ 투여후(投與後) 6시간부터 유의(有意)하게(p < 0.05) 증가(增加)하여 72시간까지 유지되었다. 혈중(血中) LH함량은 주사직전에 $3.0{\pm}0.3{\mu}IU/ml$였으며 $PGF_{2{\alpha}}$ 투여후 3~12시간에는 증가(增加)하였으나 그후 24~72시간 사이에는 $4.1{\mu}IU/ml$에서 $2.5{\mu}IU/ml$로 감소(減少)하는 경향(傾向)을 보였다. 혈중(血中) FSH 함량은 투여전 $3.5{\pm}0.5{\mu}IU/ml$였으며 $PGF_{2{\alpha}}$ 투여후(投與後) 3시간부터 감소하기 시작하여 72시간까지 유의차없이 약간 감소(減少)를 나타내었다. 혈중(血中) prolactin의 함량은 유의성(有意性)은 없었으나 $PGF_{2{\alpha}}$ 투여후 약간 증가(增加)하는 경향(傾向)을 보였다. 이상의 결과(結果)에서 LH함량의 최초 증가는 혈장중(血漿中) progesterone의 감소로 기인된 것이며 성선척극(性腺刺戟) hormone의 분비형태(分泌形態)는 황체(黃體)의 퇴행시에 progesterone 또는 progesterone과 estradiol-$17{\beta}$의 함량비의 차이로 인하여 상위되었다고 본다. This experiment was conducted to examine the $PGF{2{\alpha}}$-induced changes in concentrations of ovarian and pituitary hormones of Korean native goats. Each goats received two injections of $PGF{2{\alpha}}$ (5mg each ; 3 hours apart) on day 10 of the estrous cycle. Jugular venous blood samples were collected at 0, 3, 6, 12, 24, 48 and 72 hours postinjection for quantification of LH, FSH, prolactin, progesterone and estradiol-$17{\beta}$. The results were summarized as follows ; The blood serum concentration of progesterone was decreased from pretreatment level of $4.15{\pm}1.8ng/ml$ to $2.52{\pm}1.2ng/ml$ (about 60%) within 3 hours and to $0.81{\pm}0.3ng/ml$ at 12 hours of the $PGF{2{\alpha}}$ injection. After 12 hours, the concentrations of progesterone were less than 1.02ng/ml by 72 hours postinjection. The concentrations of estradiol-$17{\beta}$ following treatment increased (p < 0.05) over the 72 hours. Initial concentration of LH was $3.0{\pm}0.3{\mu}IU/ml$. After treatment with $PGF{2{\alpha}}$, concentrations of LH increased within 12 hours but declined 12 and 72 hours from $4.1{\mu}IU/ml$ to $2.5{\mu}IU/ml$. Prior to administration of $PGF{2{\alpha}}$, mean concentration of FSH was $3.5{\pm}0.5{\mu}IU/ml$. Concentrations of FSH declined over time in goats treated with $PGF{2{\alpha}}$ on day 10 postestrus. The mean prolactin concentrations in the blood serum after $PGF{2{\alpha}}$ treatment were not significantly different from those of the pretreatment. It is concluded that the initial increase in LH is dependent on a decrease in serum progesterone and differences in patterns of secretion of gonadotropins might be caused by differences in progesterone or progesterone-estradiol ratio when luteal regression is induced on day 10 of the estrous cycle.
