The lung is the most common site of metastasis of extrapulmonary malignant tumor. According to past reports, metastatic cancer of the lung has been found in about 2% of all patients at autopsy. But these days, a diagnosis of endobronchial metastatic cancer utilizing bronchoscopy only is not easy. Thus we need other means of gathering more informaction, such as past history, discovery of other metastatic sites, and pathologic findings with special staining and electronmicroscope, especially in cases of poorly differentiated adenocarcinoma and epidermoid cancer, which are common types of primary lung cancer. We present 5 cases of endobronchial metastatic cancer. We found endobronchial metastatic cancer 2 cases of cervix cancer (epidermoid, adenocarcinoma), 1 case of colon cancer (adenocarcinoma), hypernephroma (renal cell carcinoma), and bladder cancer (transitional cell carcinoma). Since it was impossiole to diagnose the metastatic adenocarcinoma from the cervix only with lightmicroscopic findings, we could use past history and unusual radiologic and bronchoscopic findings which was thought to be the specific endoscopic finding of metastic endobronchial cancer. The interval between the diagnosis of the primary cancer and endobronchial metastatic cancer was 25.7 months. In the future, development of immunohistochemistry, monoclonal antibody, and molecular biologic techniques will give us diagnostic clue for differential diagnosis of metastatic endobronchial cancer from primary bronchogenic lung cancer.

자돈사료내 pH와 단백질 수준의 효과를 알아보기 위하여 2개의 시험을 수행하였다. 시험 1에서는 pH 수준이 자돈의 성장과 영양소 소화율에 미치는 영향을 총 150두의 자돈(L×D×LW ; 8.82㎏ BW 30 ± 2일령)을 이용하여 1) pH 4.7, 2) pH 5.2, 3) pH 5.7 (basal diet), 4) pH 6.2, 5) pH 6.7의 다섯처리를 두었고, 시험 2에서는 pH와 단백질 수준의 효과를 알아보기 위하여 150두의 자돈을 (L×D×LW ; 5.46㎏ BW) 2×3 요인법으로 배치하였다. (조단백질 = 21.5, 24.5%, 사료 pH = 4.5, 5.5, 6.5). 또한 소화율의 측정을 위하여 시험 1에는 25두, 시험 2에는 24두의 자돈에 T-cannular를 설치하였다. 시험 1에서 pH는 자돈의 성장에 아무런 영향이 없는 것으로 나타났다. 낮은 pH사료를 급이한 구에서 사료효율이 약간 좋은 경향이 있었으나, 유의적인 차이는 발견되지 않았다. 회장 및 분소화율도 처리에 의한 효과가 발견되지 않았다. 시험 2에서는 낮은 pH 사료를 급이한 구에서 성장 및 사료효율이 개선되는 경향이 있었다 (P = 0.16). 사료효율은 단백질 수준에 의한 영향이 있었으며 (P<0.05), pH와 단백질 수준간의 상호작용이나 다른 효과는 발견되지 않았다. 회장 소화율도 단백질 수준에 의한 영향은 있었으나, pH의 효과는 methionine의 소화율에만 영향이 있는 것으로 나타났다. 전체적으로 소화율은 pH에 의한 일정한 경향이 발견되지 않았다. 본 시험의 결과는 사료의 pH 조절효과는 자돈의 나이나 사료의 종류에 따라 영향을 받는다는 것을 암시하며, 일반적으로 통용되고 있는 자돈사료는 특별한 산성화 처리가 필요하지 않은 것으로 나타났다. Two experiments were conducted to investigate the effect of diet pH and protein levels on the growth performance and nutrients digestibility in young piglets. In Exp. 1, a total of 150 piglets (Landrace × Duroc × Large White ; 8.82㎏ B W, 30 ± 2 days of age) were allotted into 5 treatments. Treatments were 1) pH 4.7, 2) pH 5.2, 3) pH 5.7 (basal diet), 4) pH 6.2 and 5) pH 6.7. In Exp. 2, the effect of dietary protein and diet pH levels on the growth performance and nutrient digestibility was examined with 150 crossbreds Landrace × Duroc × Large White ; 5.46㎏ BW) piglets in 2 × 3 factorial arrangement. (21.5 and 24.5% CP and diet pH (4.5, 5.5 and 6.5)). Each treatment has 5 replications, 5 heads per replicate. For the digestibility determination, 25 pigs for Exp 1. and 24 pigs for Exp. 2. were fitted with simple T-cannula and individually fed the experimental diet. In Exp. 1, no significant difference was found in any of the criteria measured. Pigs fed low pH diets showed slightly better feed efficiency, but the difference was not significant. Both ileal and fecal nutrient digestibility were not different. A small difference was found in major amino acids digestibility, but there was no constant trend detected. In Exp. 2, pigs fed low pH diet showed a trend (P = 0.16) to grow faster than those fed high pH diet. Feed efficiency was affected by protein level (P<0.05). No other main effect was detected. Protein level affected the ileal digestibility of energy, dry matter, crude fat, methionine and threonine. The effect of pH was found only in methionine digestibility. No other main effect was found in ileal digestibility. It appeared that age of pigs and type of diet could greatly influence the effect of diet pH manipulation. Acidification of commercially available diets might have minimal effect when diet contained high portion of high quality feed ingredients.

다른 광물질과 혼합된 크롬 피콜린산 급여가 비육돈의 성장 , 도체특성 , 혈액성상에 미치는 영향

본 시험은 여러 가지 광물질과 혼합된 크롬 피콜린 산을 첨가한 사료의 급여가 비육돈의 성장, 도체특성, 혈액성상에 미치는 영향을 알아보기 위하여 수행되었다. 개시체중이 69㎏인 총 513두의 비육돈을 돈방당 16∼21두씩 수용하여 사양시험을 수행하였으며, 9마리가 대사시험에 사용되었다. 처리구는 2개의 단백질 수준별 대조구 (Con 12, Cen 14)와 외산 크롬 피콜린산 (CrP-CaCO₃ ; Prince사 제품). 크롬 제오라이트 (CrP-Zeolite 12, 14), 국산 크롬 피콜린산 1 (CrP-CaCO₃; KIST 개발), 크롬 피콜린산-산화아연 (CrP-CaCO₃-ZnO 12, 14) 그리고 국산 크롬 피콜린산 2 (CrP-CaCO₃ ; M. H. Lee 개발)이었다. 성장성적에 있어서는 일당중체량, 일당사료섭취량, 사료효율 등 모든 조사항목에서 처리구간의 차이가 발견되지 않았으나, 등지방 두께는 크롬 피콜린산 첨가에 의해 감소하는 경향이 발견되었고, 이러한 경향은 출하체중이 무거울수륵 뚜렷하게 나타났다. 도체등급은 크롬 제오라이트구와 크롬 피콜린산-산화아연처리구에서 높게 나타났으며, 혈액내 콜레스테를의 함량도 크롬 제오라이트구와 크롬 피콜린산-산화아연처리구에서 대조구에 비해 유의적으로 감소하였다 (p<0.05). 크롬 피콜린산-산화아연처리구와 크롬 피콜린산구에서 건물 및 단백질 소화율이 향상되었다 (p<0.05). This experiment was conducted to investigate the effects of chromium picolinate in different combinations with minerals on growth, carcass characteristics, serum traits and nutrient digestibility in finishing pigs. Five-hundred and thirteen pigs (69.0 ㎏ of initial weight) were assigned to 9 treatments, each containing three replicates of sixteen to twenty-one pigs each. Additional nine pigs were used in a digestion trial. Treatments were two controls (12% CP and 14% CP), foreign CrP-CaCO₃, two CrP-Zeolite (12% CP and 14% CP), domestic CrP-CaCO₃ 1, CrP-CaCO₃-ZnO (12% CP and 14% CP) and domestic CrP-CaCO₃ 2. ADG was not significantly different among the treatments. Tenth rib backfat thickness tended to be decreased by feeding diet with CrP. Carcass grade was improved by using zeolite and CaCO₃ + ZnO along with CrP in diets. Serum cholesterol level was significantly reduced by feeding diets containing CrP with CaCO₃ + ZnO or Zeolite compared with the control. Supplementation of Cr with CrP-CaCO₃ + ZnO or CrP-CaCO₃ in diets significantly improved the digestibility of crude protein and dry matter (p<0.05). The excretion of nitrogen was lower in pigs fed diets containing Cr regardless of the combinations with minerals. The excretion of phosphorus was lowest in the CrP-CaCO₃ + ZnO group which showed the highest phosphorus digestibility.

Midazolam maleate, a water soluble banzodiazepine unlike diazepam, was synthetized by Walser and Fryer in 1975. In order to ealuate the effectiveness as an induction agent for general anesthesia, 22 elective surgical patients belonging to ASA classification 1 and 2 were selected. And ten patients (male 7, female 3, average 33.5 years old) were induced with midazolam maleate 0.2mg/kg and twelve patients (mdale 7, female 5, average 32.5 years old) with diazepam 0.3mg/kg. The results were summarized as follows. 1) Anesthesia was induced in all of midazolam group by one intravenous injection, but only 6 patients of diazepam group could induced by one injection and the other 6 patients needed 2 or more injections. 2) The changes of blood pressure and pulse rate after induction and intubation were almost similar in the two groups, but greater individual variation was seen in diazepam group. 3) A buring sensation following intravenous injection was noted in 11 cases of diazepam group, but none in midazolam group and no phlebitis in either group. From the above results, diazepam and midazolam are almost similar in nature but midazolam is definitely effective as an induction agent and has less side effects. Therefore midazolam maleate is regarded as a more effective agent than diazepam as an induction for general anesthesia.

We report a case of acute renal failure with severe loin pain and patchy renal vasoconstriction after exercise. An immediate postcontrast computed tomogram of this case shows multiple patchy areas of poor contrast enhancement in the cortex of the both kidneys. A 24-hours delayed scan without further injection of contrast dye shows multiple wedge-shaped contrast enhancement in the coincident areas of poor enhancement in the immediate scan. The 2 and 5 days delayed scans show that wedge-shaped contrast enhancement becomes disappeared gradually to the renal cortex, and the 8 days delayed scan shows complete disappearance of contrast enhancement. The renal scintigrams with technetium-99m-methylene diphosphonate and dimercaptosuccinic acid show diffuse increased uptakes and multiple patchy photon deficient areas in the both kidneys respectively. The follow-up renal scintigrams show nearly normal findings, This patient had an uneventful hospital course and recovered completely without dialysis.

Phenochromocytoma is a catecholamine-secreting tumor, most of which grow at the adrenal gland. About 109p Of pheochromocytomas are detected at the extra-adrenal chromaffine tissues and are called paraganglioma. The main symptoms of pheochromacytoma include hypertension, headache, palpitation, and sweating. Gastrointestinal symptoms such as abdominal pain, constipation, and vomiting are found in 20∼40% of patients with pheochromocytoma, but these are usually overlooked because of the severe, prominant cardiovascular symptoms. Intestinal pseudo-obstruction without hypertension in pheochromocytoma is very rarely found. It is caused by the decreased motility of the intestine and the over-contraction of the intestinal sphincter, which are caused by the unbalanced activation of α-and β-adrenal receptors. It can be hypothesized that catecholamine receptors in the cardiovascular system are down-regulated or desensitized, but those in the intestine remain intact. We report herein a case of pheochromocytoma in which intestinal pseudo-obstruction was the main presenting clinical manifestation. Symptoms of intestinal pseudo-obstruction were completely relieved by administration of phenoxybenzamine, an α-receptor blocker, and excisional surgery.

In the processing routine, any function among (1) editing (2) updating (3) printing (4) deleting could be selectively performed. In the output routine, Hanguel characters could be selectively printed in the 3 different sized character forms, i.e., 16×16 dot, 24×24 dot, and 32×32 dot size.

경막외마취 확산의 비교관찰 제 1 보 Bupivacaine-Lidocaine

김영석,김완식,김인규,김흥대,안기량,김교상 대한마취과학회 1980 Korean Journal of Anesthesiology Vol.13 No.1

Epidural anesthesia is widely practiced for lower abdominal operation and delivery in many hospital and its complication in minimal compared with spinal anesthesia. Lidocaine has been used extensively for epidural anesthesia with very satisfactory results. It has a very rapid onset of action, producing complete analgesia and has a reasonable duration of action(about 1-1½hr). A concentration of 1. 5% lidocaine causes effective sensory and autonomic blockade but it is unlikely to produce motor paralysis. More recently, bupivacaine(0.5%) has tended to supplement lidocaine as the drug of choice of epidural anesthesia. Firstly, the duration of action is longer. Secondly, it has better affinity for the tissue so that less will be absorbed into the circulation, thus reducing the risk of a toxic reaction. Thirdly, when used with a continuous technique, there is much chance of tachyphylaxis. Using a standardized anesthesia technic, we compared level of sensory anesthesia with a 0. 5% bupivacaine and 1. 5% lidocaine uder elective and emergency surgery. When equal volume of local anesthetic solution were injected(20 ml of 0.5% bupivacaine and l. 5% lidocaine) there were no statistically significant differences in sensory level in bupivacaine and lidocaine, but the duration of anesthesia in bupivacaine from 2 to 3 times longer than lidocaine.
