In this paper, we propose a method of analysing the relation between the patient's face color and his(her) kidney disease using image processing technology. This method is based on the ocular inspection which is one of the most famous diagnosis methods used in the oriental medical system. The way of processing and analysing the face image, which is for visualization and objectification of the color difference, is included. The objects are selected from the patients who suffer the kidney disease and use the hemodialyzer. Their facial images and clinical data are collected. From these data, we propose a hypothesis that the color of the patient's face is changed according to the patient's kidney state. At the same time, we present two algorithms of extracting the specific part of face which can identify the state of the patient's kidney and tracing the history of the color's change. This proposed method is evaluated through the practical experiments and their analysis.

1bis study investigated the antioxidative effect in kidney of senescence-accelerated prone SAMP8 mice with calorie restriction. 4-weeks-old SAMP8 female mice were divided into 4 groups according to the experimental feeding period: for 4, 8, 12 month, and at natural death. Each group was subdivided into 2 groups, with thirteen mice each one, as ad libitum group and as dietary restriction group (60% of ad libitum feeding amount). After feeding for a given period, the mice were sacrificed to get the following results: among the experimental groups, there wereno significant differences in xanthine oxidase (XOD) activity in their kidney tissues. The contents of cytochrome $P_{450}$ decreased in ad libitum group and dietary restriction group by age. The activity of NADPH-cytochrome $P_{450}$ reductase showed a trend similar to cytochrome $P_{450}$. Superoxide radical content increased with age. At the 4th, 8th and 12 months of the experimental period, the activity in the dietary restriction group was less than that of ad libitum group by as much as 17% 14% and 14% respectively. For hydrogen peroxide, the contents were increased in the ad libitum group with age, while no correlation between content and age was observed in the dietary restriction group. In the 8th and 12th months of the experimental period, the were in the dietary restriction group less than that of ad libitum group counterpart as much as 17% and 20o/c, respectively. For the cellular membrane stability of the kidney, no significant correlation with age was observed in either the dietary restriction group or the ad libitum group. However at the 12th month of the experiment, however, the stability in the dietary restriction group was 11 % higher than that in the ad libitum group. In conclusion, with these results obtained from the SAMP8 mouse model, we demonstrate that dietary restriction has the effects of anti-oxidation and anti-senescence in the kidney.

The relation of endocrine in the western medicine and zangfu-organ functions in Korean medicine, related to growth disturbance, was studied and derived the following results. 1. The hormone most related to growth disturbance is, directly secreted from the anterior pituitary or is stimulated and secreted in the target grands, growth hormone, thyroid, adrenocortical hormone, gonadial hormone and is insulin secreted from $\beta$ cell of langerhans' slands of pancreas. 2. the pituitary has the most close relation with the kidney in the five zang-organ. Because the kidney is innate origin(先天之本) and promotes qi and blood(生化氣血), stores the essence of life(藏精), dominates the bones(主骨) and promotes the marrow(生骨髓). Especially it is connected with brain(通於腦). 3. In the children growth, the endocrine action in the pituitary has the most close relation with the kidney, As in the reports of the brain and spinal cord, bone, store essence of life, sexual maturation and decline(kidney-qi, sexual functions of both sexes(天癸)) etc, and cause of cretinism, dwarf in the main subject. 4. Somatomedin is the most important factor of the growth factors, IGF in another word. The unification of IGF and secretion is controlled firstly according to growth hormone, however is very closely related to the nutrition status in the non-hormonic causes. Also, it is affected very much by the insulin. 5. Insulin is one of the important hormone related to the growth and is secreted from the pancreas. Pancreas belongs to the functional system of spleen in oriental medicine, thus the growth disturbance, occurred due to error in insulin secretion and nutrition(in another words, the lack of postnatal essential substance from food-stuff(水穀精氣)), is closely related to the spleen. 6. From the results driven above, the hormone action of endocrine and problem in secretion, related to the growth disturbance, must be focused on the differentiation of symptoms and signs of the kidney and the spleen in oriental medicine.

1. Objectives The purpose of this study is to investigate the anti-aging and anti-oxidant effects of Hyeongbangjiwhang-tang decoction(HGD) in SD rats. 2. Methods This experiment was used the tissue of kidney, bladder and spleen cells of 6, 52 and 68 weeks old SD rats. Each age group was again divided into three groups. One group, as normal group, was not-treated cells, another group, as control group, was saline-treated cells, and the last group, as experimental group, was HG-treated cells. After culture for 48 hours, each groups measured the level of SOD, GSH, MDA and NO in the tissue of kidney, bladder and spleen cells. 3. Results and Conclusions The activity of SOD were significantly increased in kidney cell of 68 w-HGD group, bladder cell of 52 w-HGD group and in spleen cell of 52,68 w-HGD group compared with those of the control groups. The level of GSH were significantly increased in bladder cell of 52w-HGD group and in spleen cell of 68w-HGD group compared with those of the control groups. The level of MDA were significantly decreased in bladder cell of 68 w-HGD group and in spleen cell of 68w-HGD group compared with those of the control groups. The level of NO were significantly decreased in kidney cell of 68 w-HGD group, bladder cell of 52, 68w-HGD groups, and in spleen cell of 68w-HGD group compared with those of the control groups. These results suggest that HGD(Hyeongbangjiwhang-tang) has anti-oxidant effects in aged rats.

This study was performed to investigate the effect of dietary protein and calcium levels on cadmium detoxication in rats. Seventy male Sprague-Dawley rats weighing 208 $\pm$ 19 g were blocked into 10 groups of 7 animals according to body weight. Five groups were fed 15% protein-0.6% calcium diet with 100ppm cadmium in drinking water for first 15days and the other 5groups fed same diet without cadmium in drinking water for same period and served as controls. After this 15-day intoxication period, each one of cadmium intoxication and control groups were fed each of 4 kinds of detoxifying diets different with protein(40%, 15%) and calcium(1.3%, 0.6%) levels without cadmimum in drinking water for following 15 days of detoxifying period. Results were summarized as follows: 1) Food intake, body weight gain, F.E.R. and weights of liver, kidney and femur were increased by detoxifying diets and high protein diet was most effective in weight gains of liver and kidney. 2) When cadmium and metallothionein contents of initial intoxication group and those of all detoxication groups were compared, cadmium and metallothionein contents in the liver were not changed, but those in kidney increased, and those in intestine decreased markedly. 3) Only dietary protein level affected cadmium and metallothionein distribution among organs, and cadmium contents of whole blood, liver, kidney and femur were lower in high protein diet, but metallothionein contents in liver and kidney were higher in high protein diet. 4) Gel filtration chromatogram showed that most of cadmium in the cytosol was bound to metallothionein fractions in high protein-high calcium group. Results obtained indicated that high protein diet was effective in cadmium detoxication by increasing the induction of metallothionein synthesis. But high calcium diet did not play a role in cadmium detoxication.

Radioisotope tracer experiments on the distribution and the binding of radionuclides to proteins in bivalve were carried out in order to gain further information on biochemical behavior of radionuclides in marine bivalve, Gomphina melanaegis. The radioactivities (cpm/g) of $^{65}Zn\;and\;^{54}Mn$ after 7 days exposure were highly concentrated in liver and kidney in comparison to soft parts. The gel filtration profile of $^{65}Zn$ in liver and kidney showed three elution peaks, while $^{54}Mn$ showed two peaks in liver and three peaks in kidney. On the gel filtration of $^{137}Cs$ in liver and kidney, most of $^{137}Cs$ were eluted on one peak. Thus, it was considered that each radionuclide was bound to different proteins in liver and kidney of bivalve.

Urinary obstructions from ureteral calculi are one of the causes of postrenal acute kidney injury (AKI). Here we present a case of AKI caused by a 4 mm ureteral calculus with postobstructive diuresis following the spontaneous passage of the calculus. A 13-year-old girl who underwent nephrectomy for the removal of a neuroblastoma eight years previously, visited our institution because anuria had developed over the preceding five days. The serum creatinine level was elevated at 13.4 mg/dL. Radiological examinations showed the right solitary kidney with moderate hydronephrosis and a 4 mm calculus in the upper right ureter. The patient immediately underwent hemodialysis. After the ureteral calculus was passed spontaneously on day 2 of hospitalization, urinary output increased to more than 5,200 mL per day. Intravenous fluid replacement with careful monitoring of weight, intake, output, and serum and urine electrolytes was performed. On day 5 of hospitalization, the patient's condition stabilized.

Background: Nephrotic syndrome (NS) is the most common glomerulopathy in children. Acute kidney injury (AKI) is a common complication of NS, caused by severe intravascular volume depletion, acute tubular necrosis, interstitial nephritis, or progression of NS. However, the incidence and risk factors of childhood-onset NS in Korea are unclear. Therefore, we studied the incidence, causes, and risk factors of AKI in hospitalized Korean patients with childhood-onset NS. Methods: We conducted a retrospective review of patients with childhood-onset NS who were admitted to our center from January 2015 to July 2017. Patients with decreased renal function or hereditary/secondary NS, as well as those admitted for management of other conditions unrelated to NS, were excluded. Results: During the study period, 65 patients with idiopathic, childhood-onset NS were hospitalized 90 times for management of NS or its complications. Of these 90 cases, 29 met the Kidney Disease Improving Global Outcomes criteria for AKI (32.2%). They developed AKI in association with infection (n = 12), NS aggravation (n = 11), dehydration (n = 3), and intravenous methylprednisolone administration (n = 3). Age ${\geq}9$ years at admission and combined use of cyclosporine and renin-angiotensin system inhibitors were risk factors for AKI. Conclusion: AKI occurred in one-third of the total hospitalizations related to childhood-onset NS, owing to infection, aggravation of NS, dehydration, and possibly high-dose methylprednisolone treatment. Age at admission and use of nephrotoxic agents were associated with AKI. As the AKI incidence is high, AKI should be considered during management of high-risk patients.

Present experiments were undertaken for the purpose of clarifying the effect of repeated halothane anesthesia on the liver and kidney function. Nine mongrel dogs were divided into three groups. The group one dogs were anesthesized once(control group) and the other two groups twice and trice respectively on 10th day of previous anesthesia experimental groups. Hematological examinations and blood chemical assays were undertaken during the period from one hour to 10 days after the anesthesia. From these experiments fellowing results were obtained; 1. No significant changes of erythrocyte count were recognized in both the control and experimental groups after the halothane anesthesia. 2. The total leukocyte counts of experimental groups showed significant decrease on one hour and subsequent increases after the anesthesia. 3. No significant changes were observed in SGOT, SGPT, ALP, BUN and serum glucose values in both the control and experimental groups. 4. The total serum protein values showed a tendency to decrease on the first hour of halothane anesthesia in both the control and experimental groups. From these results it may be concluded that the repeated halothane anesthesia done 10th day of previous anesthesia do not affect the liver and kidney function in dogs.

The purposes of this study were to characterize the disposition of sulfathiazole(ST) and to investigate the effects of sodium bicarbonate on the disposition of ST in broiler chicks(2.5～3.0kg). Animals were given ST acutely(10～80mg/kg, PO), and plasma, kidney, muscle, heart, liver and spleen samples were collected and analyzed for ST by high performance liquid chromatography. The plasma and tissue data was consistent with a one-compartment pharmacokinetic model. The drug is rapidly but incompletely(2.5～3.87%) absorbed with peak plasma and tissue levels being achieved within one hour after dosing. The plasma and tissue levels depended on drug dosage, and the descending order in concentration of ST was kidney > plasma > heart > muscle $\geq$ spleen $\geq$ liver from animals sacrificed at one hour after dosing. Moreover, significant positive correlations(r>0.9) existed between plasma and tissue levels of ST. In addition, sodium bicarbonate pretreatment decreased plasma level, indicating that an alkalinization stimulate the excretion of ST. Results of this study suggest that oral application of ST was rapidly absorbed and eliminated, and confirmed that tissue residues of ST can be estimated from plasma drug concentration in broiler chicks.
