The radioactive $^{131}I$-rose bengal serial scintiphotography was performed in 62 patients with the hepatobiliary diseases and in 20 normal subjects. This approach permitted visualization of the hepatic uptake of $^{131}I$-rose bengal from the circulation and its excretion into the biliary trees and the intestines. In some of these patients, gallbladder function was examined, using eggs as a gallbladder constrictor. The time of maximum hepatic uptake was well correlated to the conventional biochemical liver function tests. In addition to $^{131}I$-rose bengal scintiphotography, $^{198}Au$-colloid scintiphotography was also performed to make comparison of these two tests. The results obtained were as follows: 1. In normal subjects, the maximum hepatic uptake of $^{131}I$-rose bengal occurred at $23{\pm}2.9$ minutes, the initial hepatic excretion at $34{\pm}5.1$ minutes, the visualization of the gallbladder at $29{\pm}5.7$ minutes and the intestinal visualization at $54{\pm}25.8$ minutes. The radioactivity in the gallbladder decreased to $10.7{\pm}5.0%$ one hour after the ingestion of eggs. 2. In the patients with cirrhosis of the liver, there was a delayed and decreased hepatic uptake. The maximun hepatic upake occurred at $43{\pm}12.9$ minutes. The differences in the results of uptake between the cirrhotic and the normal group were statistically significant. The initial hepatic excretion occurred at $60{\pm}18.5$ minutes and had tendency of delaying compared with the normal controls. The gallbladder was visualized in 13 of 16 cases (81%) and its visualization occurred at $49{\pm}14.6$ minutes with a tendency to be delayed compared with the normal controls. The intestinal visualization occurred at $63{\pm}15.8$ minutes and its delaying tendency was somewhat more prominent. 3. In patients with hepatitis, the maximum hepatic uptake occurred at $59{\pm}21.4$ minutes and was significantly delayed. The initial hepatic excretion occurred at $82{\pm}34.3$ minutes and the results revealed a delaying tendency. The gallbladder was visualized in 15 of 20 cases (75%) at $57{\pm}18.7$ minutes, which was significantly delayed. The Intestinal visualization was noted in all cases with marked delay. 4. In patients with obstructive jaundice, the maximum hepatic uptake was noted at $83{\pm}14.7$ minutes, showing the most significant delay. The hepatic excretion into biliary trees and intestines was not entirely noted in all cases except the only one case with gallbladder visualization. 5. In patients with cholelithiasis, the maximum hepatic upake and the initial hepatic excretion were slightly delayed with mean times of $39{\pm}11.2\;and\;48{\pm}17.1$ minutes respectively. The visualization of the gallbladder was demonstrated in 10 of 17 cases (59%) and occurred at $52{\pm}25.6$ minutes with a slight delay. The intestinal visualization occurred at $67{\pm}47.7$ minutes and was slightly delayed. $^{131}I$-rose bengal in the gallbladder remained high, $49.3{\pm}21.3%$, which suggested quantitatively decreased power of gallbladder constriction. 6. The time of the maximum hepetic uptake was correlated well to BSP retention and serum alkaline phosphatase ativity. However, the maximum hepatic uptake had no definite correlation with serum albumin, serum globulin, TTT, serum cholesterol, SGPT or SGOT. 7. In the diagnosis of the hepatobiliary diseases with jaundice, $^{131}I$-rose bengel serial scintiphotography has proved to be more useful than $^{198}Au$-colloid scintiphotography. With these results, it could be justified that $^{131}I$-rose bengal scintiphotography is an excellent diagnostic aid for dynamic hepatobiliary function studies in the clinical practice.

Effect of Jeo Ryong-Tang water Extract on Renal Function in Rabbit and Dog. In order to investigate the Pharmacological action of Jeo Ryoung-Tang on renal function, this study was performed in rabbit and dog, making use of it's water extract. Jeo Ryoung-Tang water extract (JRWE), when given into ear vein of rabbits, produced diuresis in a small dose, but antidiuresis in a large dose. Diuretic action of JRWE accompanied the increase of glomerular filtration rate (GFR), renal plasma flow (RPF) and amounts of $Na^+$ in exdreated in urin, but fractional excretion of filtered $Na^+$ was not changed. JRWE, when injected into proleg's vein of dog, produced diuresis, At this time, changes of renal function were similar to that of diuresis in rabbit. JRWE, when infused into a renal artery of dog, exhibited the diuresis in both kidney. It is thought that JRWE, when given into vein of rabbit or dog, induces the diuresis, and the mechanism of it's diuresis is the increase of renal plasma flow through secondary action by some endogenous humoural substance.

Mammalian cardiocytes secrete atrial natriuretic peptides (ANPs) into plasma, which cause marked natriuresis, diuresis, vasorelaxation and inhibition of hormone secretions. Aging influences the ability of the kidney both to conserve and to excrete sodium; i.e., in old animals, the excretory capacity of sodium is reduced and the time required to excrete sodium load is prolonged. Therefore, it is possible that animals differing in ages may respond differently to ANP. In the present study, we determined whether the renal, hormonal and vascular effects of ANP may be influenced by aging in conscious rabbits. The plasma renin concentration decreased with aging but plasma ANP concentration was significantly lower only in 24-month-old rabbits. Plasma aldosterone concentration and atrial ANP content did not change by aging. In 1-month-old rabbits, ANP (atriopeptin III, 3 ug/kg) administered intravenously caused hypotension and decreased in plasma renin and aldosterone concentrations, but did not cause diuresis and natriuresis. In 2 to 5 month-old rabbits, ANP caused hypotension, decreases in Plasma renin and aldosterone concentrations and marked renal effects. However, in 24-month-old rabbits, all the above effects of ANP was blunted. With hydration of physiological saline at a rate of 15 ml/kg/h for 2hr, urine volume and glomerular filtration rate did not change but the electrolyte excretion as well as fractional excretion of sodium significantly increased. The plasma concentrations of active renin and aldosterone were decreased but plasma inactive renin and ANP concentrations were increased. The changes in renal function and plasma level of hormone showed no differences in different ages. These results suggest that the peripheral vascular receptors to ANP may develop earlier than those in the kidney, and the attenuated vascular and renal responses to ANP in the old age may be due to age-related modifications in renal function and blood vessel.

The aim of this experiment was to elucidate the effects of Saseuptang water extract on the renal function plasma renin activity and plasma levels of atrial natriuretic peptide and aldosterone in rat The results were as follows; 1. Water balance decreased significantly after the administration of Saseuptang water extract, 0.4 and 0.8ml/kg. 2. Urine volume increased significantly after the administration of Saseuptang water extract, $0.4\;m{\ell}/kg$. 3. Urinary excretion of chloride increased significantly after the administration of Saseupthang water extract, $0.8\;m{\ell}/kg$. 4. Free water clearance increased significantly after the administration of Saseuptang water extract, $0.8\;m{\ell}/kg$. 5. Urinary excretion of creatinine increased significantly after the administration of Saseuptang water extract, $0.8\;m{\ell}/kg$. 6. Plasma levels of atrial natriuretic peptide (ANP) decreased significantly after administration of Saseupthang water extract, $0.8\;m{\ell}/kg$. These results suggest that the changes of urine volume after the administration of Saseuptang water extracts are related to the increments of glomerular filtration rate and free water clearance, and it is suggested that the changes of renal function by which Saseuotang may related to the renin-angiotensin and atrial natriuretic peptide system.

The aim of this study was to investigate the effect of supplemental recombinant bovine somatotropin (rbST) and cooling with misters and fans on renal function in relation to regulation of body fluids in different stages of lactation in crossbred Holstein cattle. Ten, 87.5% crossbred Holstein cattle were divided into two groups of 5 animals each, housing in a normal shaded barn (NS) and in a shaded barn with a mister-fans cooling system (MF). The experiment in each group was divided into 3 phases, early- (Day 75 postpartum), mid- (Day 135 postpartum), and late stage of lactation (Day 195 postpartum). The pre-treatment study was conducted on the starting day of each stage of lactation and the treatment study was performed after the end of the pre-treatment, during which the animal was injected with 500 mg of rbST (POSILAC) every 14 days for three times. During the study, ambient temperature at the hottest period daily in the MF barn was significantly lower, while relative humidity was higher than that of the NS barn. The temperature humidity index (THI) in both barns ranged from 79-85 throughout the periods of study. Cows in the MF barn showed a lower rectal temperature and respiration rate as compared with cows in the NS barn. The effect of rbST administration increased both rectal temperature and respiration rates of cows housed in either the NS or MF barn. Milk yield significantly increased in cows treated with rbST in all stages of lactation. Increases in mammary blood flow, accompanied by increases of total body water (TBW), extracellular fluid (ECF), blood volume (BV) and plasma volume (PV), were observed in both groups of cows receiving rbST in all stages of lactation. No alterations of renal blood flow and glomerular filtration rate were observed in cows receiving rbST, but decreases in urinary excretion and fractional excretion of sodium, potassium and chloride ions appeared to correlate with reduction in the rate of urine flow and osmolar clearance during rbST administration. These results suggest that the effect of rbST supplementation to cows housed either in NS or MF barns on body fluid volume expansion is attributable to changes in the rate of electrolyte excretion by the kidney. The increased availability of renal tubular reabsorption of sodium, potassium and chloride ions during rbST treatment was a major factor in retaining body water through its colligative properties in exerting formation of an osmotic force mechanism.

목적 : Rhabdomyolysis에 의해 유발된 급성 신부전시 나타나는 신장세뇨관 세포에서 물질이동의 저해가 단삼 추출액에 의해 방지될 수 있는 지를 조사하였다. 방법 : 토끼에 50％ glycerol을 10ml/kg씩 대퇴근육내 주사한 후 뇨와 혈액을 채취하여 신기능을 측정하고, 신피질 절편을 분리하여 실험하였다. 결과： 토끼에 50％ glycerol을 10ml/kg씩 대퇴근육내 주사한 결과 사구체여과율의 감소와 Na 배설분율의 증가가 나타남으로서 glycerol 주입이 rhabdomyolysis에 의해 급성신부전이 유발되었음을 보였다. Glycerol을 주사하기 전 7일 동안 단삼 추출액 (0.05%)을 0.3 g/kg씩 경구 투여한 결과 glycerol에 의해 유발된 사구체여파율의 감소와 Na 배설분율의 증가가 유의하게 방지되었다. glycerol만을 주사한 동물에서는 포도당과 인산의 요배설분율이 각각 현저하게 증가하였으나, 이러한 증가는 단삼 추출액에 의해 억제되었다. 급성신부전이 유발된 신장피질에서 분리한 brush-border membrane vescicles (BBMV)에서 포도당과 인산의 이동은 정상 신장과 비교하여 유의한 감소가 나타나고, microsomal fraction에서 측정한 Na＋-K+-ATPase 활성도 억제되었다. 이러한 억제현상은 단삼 추출액을 전처치한 결과 방지되었다. 급성신부전이 유발된 신장피질 절편에서 유기 음이온인 P-aminohippurate 이동과 유기 양이온인 tetraethylammonium의 이동이 억제되었고, 이러한 변화는 단삼 추출액에 의해 방지되었다. Rhabdomyolysis에 의해 유발된 포도당과 인산의 배설분율의 증가는 항산화제로 잘 알려진 DPPD 전처치로 방지되었다. 결론 ： Rhabdomyolysis에 의한 급성신부전의 유발 과정에 반응성 산소기가 중요한 역할을 할 가능성을 보이고 있고, 단삼 추출액 전처치는 Rhabdomyolysis에 의한 급성 신부전시 나타나는 근위세뇨관에서 물질의 재흡수 장애를 방지하고 있다. 단삼 추출액의 방지 효과는 항산화작용에 기인할 것으로 사료된다.

All living things including human being consist of soul(spirit) and body. Soul is the root of a life and body frames it. I wrote this paper to tell how internal injury due to endogenous etiological factors and affection due to exegenous pathogenic factors, affect the internal organs and the external bodily from. This paper begins with description of the patterns of disharmony of the internal organs. General disorders of each Five-Jang(五藏) an be classified into two types of soul and body. The Liver and the Heart which lead changing to Yang(陽) of vital energy, have close relationship with spiritual symptoms because spirit is related to Yang. The Lung, Kidneys, the Spleen which lead changing to m(陰) of vital energy, mainly connected with physical disorders because body is relatively close to m. The Five-Jang are ruled by the Five-Phases(五行) system and cause troubles with Oche(五體) and the nine body orifice. Otherwise the main function of the Six-Bu(六府) is to receive food, absorb the usuable portions, and transmit and excrete waste. Therefore they can cause such problems as abdominal pain, distention, difficulty in urination, and constipation. The spleen is responsible for sending Grain-Ki)穀氣) 내 that is closely connected with the six-Bu. The Gall bladder takes care of control of giving out spirit. That's why it presents many symptoms related to the spirit that is ruled by the Five-Jang. Patterns of disharmony of external bodily form is influenced by the state of Maridians. Bodily forms get divided into many parts by the function of six-meridians(六經) to which they belong. Six-meridians have their own function related to excretion, related to excretion, retention, and balance(開闔樞). If local bodily froms get affected by pernicious influences, the Meridians to which they are attached will lose harmony and connot fulfil their own functions. Because the meridian symtem unifies all parts of the body, the whole body will be under the influence of the affection although local parts of the bodily forms get affected. Therefore the symptoms of disharmony should be considered in a synthetic view. There are however, also cases which should be focused on the very meridian channels affected. Disorder within a Meridian generates derangement in the pathway make it not to benefit the muscles and skin belong to it. Because the meridians connect the interior organs with the exterior bodily form, they are influenced by each other.

This experiment was carried out to establish a proper method of indocyanine green(ICG) excretion test for a applicable liver function test in dogs. The half life(T1/2), fractional clearance rate(KICG) and retention rate after injection of ICG with or without administred carbon tetrachloride($CCl_4$) were also invested. The results obtained were as follows ; 1. The maximum absorbance of ICG in plasma was at 810nm. 2. Half life and fractional clearance rate when administered 0.25 and 0.50mg of ICG per Kilogram body weight were $6.33{\pm}0.58$ minutes and $0.11{\pm}0.99$/minute in the former, $10.01{\pm}1.0$ minutes and $0.07{\pm}0.007$/minute in the latter, respectively. The ICG removal rate was exponentially linear for the first 15 minutes after injection both, of 0.25 and 0.50mg of ICG. 3. One day following the administration of $0.0042m{\ell}\;CCl_4$ kilogram body weight which injected 0.50mg of ICG, half life was more longer and fractional clearance rate was significantly reduced than that of ICG single injection. 4. Plasma retention rate when 15, 30, 45 minutes after injection dose of 0.25 and 0.50mg ICG per Kilogram body weight, $14.7{\pm}4.8$, $5.1{\pm}3.1$, $2.6{\pm}1.6%$ in the former, $26.9{\pm}1.8$, $11.1{\pm}2.4$, $4.8{\pm}1.3%$ in the latter, respectively. However, after administration of $CCl_4$, plasma retention rate of ICG at a dose of 0.50mg, it was $39.3{\pm}0.9$, $16{\pm}2.9$, $10.7{\pm}0.1%$, respectively. 5. Plasma enzyme(AST, ALT, r-GTP) activities administered with $CCl_4$ were increased, but there was no change which injected any dose of single ICG injection. From these results, ICG excretion test to dog is applicable to evaluation of liver function in both clinical and research.

This research aims to study the changes In gastrointestinal function attributed to aging In human. The thresholds for recognition and detection of flavors became elevated and salivary gland acinar cells decreased in the old age. But most esophageal function remained relatively Intact. Although gastric emptying time has been slowed with aging, the total intestinal transit time did not differ. Atropic gastritis due to H. pylori in old man decreased secretion of acid and Intrinsic factor and absorbability of calcium and iron. Pancreatic secretion is droned in older persons. Prevalence of gallstones rised with age. Liver size and portal blood flow decreased significantly with age. Mucosal surface area has been reported to be slightly diminished in the aging man. Glucose transporters decreased and Insulin tolerance Increased. Absorption of aromatic amino acid is diminished with age. Dietary protein In that aging human increased fecal nitrogen excretion. Vitamin A tolerance increased. Vitamin D receptor concentration decreased and resistance to 1,25-(OH)2D3 action increased. Permeability of aging small Intestine Increased. Zinc balance dirt not differ Copper absorption appeared not to be significantly affected by age. Neurotensin secretion decreased thus slowed colonic peristaltic movements and Intestinal mucosal growth.
