A 2-year-old 16-kg, intact female lindo was presented with weight loss and poor hair coat. Abnormal serum biochemical values included mild hypokalemia (3.9 mmol/L, reference range 4.37 to 5.35 mmol/L) and mild hyperglycemia (124 mg/dl, reference range 65 to 118 mg/dl). in the complete blood count and diagnostic imaging examination, abnormal changes wer not seen. The analysis of urine sample obtained from cystocentesis revealed glucosuria (> 100 mg/dl) and mild proteinuria. Repeated analysis after admission showed persistent glucosuria and hypokalemia. But blood glucose values did not exceed the renal threshold fur glucose reabsorption. To differentiate cause of the glucosuria, the glucose tolerance test and the low-dosage dexamethasone suppression test were indicated. Results of both tests were normal. In addition, the serum total thyroxine $(T_4)$ value was within normal range. The arterial blood gas analysis showed no remarkable changes. The fractional reabsorption rates of amino acids and phosphorus were calculated above $97\%$. Based on these findings, the dog was diagnosed as renal glucosuria due to proximal renal tubular dysfunction. But this persistent renal glucosuria with hypokalemia may be the initial sign of Fanconi's syndrome or proximal renal tubular acidosis.

This study was intended to examine the zinc status and effect of zinc supplementation on the zinc nutritional status of the elderly living in the Ulsan area. The zinc intake of 207 subjects(male 97, female 110) was measured by a 24-hour dietary recall and food frequency method. Biochemical analysis were conducted from blood and urine samples to evaluate the changes of zinc nutriture with zinc supplementation. The average dietary zinc intake of subjects was $7.7\pm{2.8mg}$ for male and $7.5\pm{2.6mg}$ for female, which were 51.3% and 62.3% of Korean RDA respectively. The first source of zinc was cereal and grain(36%), and the second was eggs and milk group(27%). After 8 weeks of zinc supplementation, the serum zinc content was significantly increased(p<0.01), although the serum copper content was not significantly decrease. Serum HDL- cholesterol level was not significantly decreased with zinc supplementation. Serum alkaline phosphatase(ALP) activity and urinary zinc excretion were significantly increased(p<0.05). The urinary Zn/Cr was not significantly increased. It is suggested from the results that the daily zinc supplementation can be effective to improve zinc nutriture.

This study was performed to evaluate the toxicity of cadmium selenide for a period of 28 days in Sprague-Dawley rats. Each of 10 healthy male and females rats per group received daily oral administration for 28-day period at dosage levels 30, 300 and 1,000 mg/kg of body weight. Mortality and clinical signs were checked, and body weight, water intake and food consumption were also recorded weekly. There were no dose-related changes in food consumption or urine volume. All animals survived to the end of study with no clinical signs or differences in body weight gain observed when compared with the control group. At the end of study, all animals including control group, were subjected to necropsy. Blood samples were collected for hematology tests including coagulation time and biochemistry analysis. Blood coagulation time and relative organ weight were unaffected by all received doses. White Blood Cell (WBC) counts significantly increased in the 300 mg/kg administered male animal group when compared to the control. Monocyte (MO) value were also increased significantly in both 300 and 1,000 mg/kg male animal group. However, Mean Corpuscular Volume (MCV) were significantly decreased compared with the control in the 1,000 mg/kg dose groups for male and female animals. Mean Corpuscular Hemoglobin (MCH) decreased significantly for female in the 300 and 1,000 mg/kg group compared to the control. Blood biochemical values of Inorganic phosphorus (IP) were significantly increased in both the 300 and 1,000 mg/kg dose groups in male animals when compared to the control. Creatinine (CRE) levels indicated significant increase in kidney function for the female, 30 mg/kg dose group when compared with control. There was a significant decrease in thymus absolute organ weight in the female, 1,000 mg/kg dose group when compared with control. Histopathological findings revealed no evidence of injury related to cadmium selenide except for one case of focal hepatic inflammation in the high dose (1,000 mg/kg) group. One case of lung inflammation was also seen in the control group. Basis on these result, the No Observable Adverse Effect Level (NOAEL) of cadmium selenide was determined to be more than 1,000 mg/kg/day for male and female rats under conditions in this study.

Urinary tract infections (UTIs) are one of the most common infections in different age groups, including children. Bacteria are the main etiological agents of UTIs. The aim of the present study was to isolate, identify, and determine the antibiotic susceptibility of bacteria isolated from children with UTIs from Baghdad, Iraq. Three hundred and two urine samples were collected from children aged 6 months to 12 years. The samples were cultured on blood agar and MacConkey agar. The selected colonies were subjected to biochemical tests and antibiotic susceptibility analysis using the Vitek^® 2 Compact automated microbial identification system. In this sample, 299 bacteria were identified, of which, 267 were gram-negative bacteria, and 32 were gram-positive bacteria. Escherichia coli (56%) was the most commonly isolated gram-negative bacteria, followed by Pseudomonas aeruginosa (14%), Enterobacter spp. (10.48%), Klebsiella pneumoniae (9.36%), Proteus spp. (7.8%), Acinetobacter baumannii (1.5%), and Morganella morganii (0.37%). Enterococcus faecalis (62.5%) was the most commonly detected gram-positive bacteria, followed by Staphylococcus aureus (37.5%). E. coli and P. aeruginosa were the most antibiotic-resistant bacteria. Among the tested antibiotics, meropenem showed 100% sensitivity, followed by imipenem (97.4%), amikacin (91.8%), and tobramycin (83.5%). In contrast, the high frequencies of resistance were observed with cefixime (93.2%), cefotaxime (78.7%), and ceftriaxone/cefotaxime (71.2%). In conclusion, carbapenems and aminoglycosides are highly recommended for the empirical treatment of UTIs, while, Quinolones, penicillins, and cephalosporins are not suggested. Frequent antibiotics susceptibility testing are warranted to determine the resistance pattern of UTI bacteria.

The purpose of this research is to compare the effdct of the new weekly iron supplementation on maternal iron and zinc nutritional status with the effect of the present daily iron supplementation. To assess the iron ad zinc status of rpegant women visiting public health center in Ulsan, interview for dietary survey and general aspect of each subject was given and biochemical analysis of blood and urine was performed. The study subjects were divided to two groups randomly, but the subjects whose Hgb level was very low were allocated in daily group ethically because theeffect of weekly supplementation was not yet established as safety. Daily group received 80mg elemental Fe(250mg Fe as ferrous sulfate) per day for 100days, while weekly group received 160mg elemental Fe once a week for 15 weeks. After treatement, Hgb(p<0.01), Hct(p<0.01) , serum iron(p<0.05) and serum ferritin(p<0.001) in weekly group but RBC, Hgb , Hct , serum iron and serum iron and serum ferritin increased slightly. After correction for the initial Hgb by including it in the MANIVA, the difference in treatment effects of Hgb and TIBC between groups was statistically significant. The effect of weekly vs, daily iron supplementation program on zinc status was also studied. The difference in treatment effect between two groups was, however, not sifnificant. It is concluded that once weekly rion supplementation program in pregnant women was less effectgive to improve the iron status than daily iron supplementation program. However, because the weekly dose prevented a decline in Hgb as well as in ferritin, itw effect was positive , given the fact that non-supplemented women almost always exhibit a sifnificant drop in Hgb values. It seems that it will improve the iron status well if the amount or frequency of supplements is to be adjusted . Biweekly supplementation of a different dose or antother type of iron supplement, such as through a gastric delivery system, might be better.

Objective : Oriental medicines have been applied to Membranous nephropathy(MN) for the purpose on increasing renal blood flow and modulating immune activity in according to Oriental medicine theories. Magsungsinyeom-bang (MSSYB) is one of the prescription which is known to show positive results in clinic with lack of laboratorial evidence. Thus, this study was aimed to evaluate the effects of MSSYB and partially investigate the mechanisms of it. Methods : The effect of MSSYB was evaluated by the morphology for the GBM thickening, protein excretion in urine and biochemical parameters in serum using cBSA-induced MN mice model. Mice were administered with MSSYB(250 or 500 mg/kg) or PBS for control group from experimental week 3 for 4 weeks. Results : 24 hrs proteinuria and the concentrations BUN was significantly decreased in the MS groups compared to the control group while the concentrations of serum albumin was higher in the MS groups than control group. MSSYB didn't affect the ratio of CD3e+/CD or 19CD4+/CD8 in the spleen and kidney, but inhibit the expression of IL-1${\beta}$, TNF-${\alpha}$, IL-6, and production of IgG and IgM. In histological analysis of kidney tissue, thickening of GBM was significantly decreased in the MS group compared to control group. Conclusions : MSSYB showed the positive results on the cBSA-induced membranous nephropathy in mice, thus, it could be a useful candidate for oriental drug for treating the membranous nephropathy in clinic.

The study was designed to assess the zinc nutritional status by gestational age of pregnant women visiting in public health centers in Ulsan. The subjects were divided into 3 trimester by last menstrual period(LMP). Interview for dietary zinc intake and general characteristics of each subjects was given and biochemical analysis of blood and urine was performed. Serum zinc concentration and urinary zinc excretion were analyzed by Flame Atomic Absorption Spectrophotometer, and alkaline phosphatase(ALP) activity was analyzed by Bowers & McComb\\`s method with Schimadzu automatic analyser. Also urinary creatinine was analyzed by Hawk\\`s method. Mean intake of zinc was 6.61${\pm}$1.57mg and did not meet the RDA(44.1% of RDA) for pregnant women by gestational age. Zn intake of 3rd trimester was significantly increased but dietary zinc was almost supplied with cereal and grain (47.30%) which were reported with low zinc availability due to phytate. Mean concentration of serum Zn in 1st trimester was 86.4${\pm}$10.5$\mu\textrm{g}$/dl, was 72.4${\pm}$10.3$\mu\textrm{g}$/dl in trimester and 65.1${\pm}$10.8$\mu\textrm{g}$/dl in 3rd trimester and was declined significantly by gestational age during pregnancy. In was concluded that a decline in serum Zn by gestional age was not influenced by amount of Zn intake. However ALP activity and urinary zinc excretion increased significantly by gestational age. Zinc nutritional status of pregnant women was not confirmed yet due to the physiological changes during pregnancy. However, the pregnant woman may be in a marginal zinc deficient status because of low amount of Zn intake and low bioavailability of Zn from dietary sources.

Objective : Recently scolopendrid aqua-acupuncture has been a good effect on pain control but it has not been known about clinical safety. The purpose of this study was to investigate acute toxicity of scolopendrid aqua-acupuncture. Method : In order to prove the clinical safety of scolopendrid aqua-acupuncture, We have observed a bacteriological examination and clinical pathology test after scolopendrid aqua-acupuncture treatment. Balb/c mice were injected intravenous with Scolopendrid aquaacupuncture treatment for $LD_{50}$ and acute toxicity test. We analyzed physical reaction(side effect)and clinical pathology test before and after Scolopendrid aqua-acupuncture treatment of mice and 20 patients suffering from pain, who admitted department of Acupunture and Moxibustion, College of Oriental Medicine, Won-Kwang University Kwangju hospital. Results : In the Blood agar plate and Nutrient agar plate, a bacteriological examination did not show a bacillus. In acute $LD_{50}$ toxicity test, there was no mortality thus unable to attain the value. Examining the toxic response in the acute toxicity test, there was no sign of toxication. In acute toxic test, running biochemical serum test couldn't yield any differences between the control and experiment groups. In the 20 patients treated with Scolopendrid aqua-acupuncture, hematologic test did not show remarkable change. In the 20 patients treated with Scolopendrid aqua-acupuncture, Liver function test(AST, ALT, ALP) showed a slight decrease on the contrary, and abnormal rate showed a decrease of 5.0% compared with previous study. Reanl function test(BUN, Cr) and abnormal rate showed a decrease of 5.0% compared with previous study. In the 20 patients treated with Scolopendrid aqua-acupuncture, Electrolyte were normal range before and after treatment. In the Urine analysis of 20 patients, Leukocyte, Protein, Glucose, Keton, Bilirubin, U-bilinogen were not detected before and after Scolopendrid aqua-acupuncture treatment, and the rest almost made no difference.

It is a great value to find an early detection of involvement of ureteric obstruction in the carcinoma of cervix. Little or no knowledge of the condition of the kidneys or the lower urinary tract are able to elucidate by the biochemical studies such as blood nitrogen or urine creatinine in carcinoma of cervix. Findings of urography delineates the condition of urinary tract stasis in the renal pelvis and ureters, however, slight stasis maybe difficult to demonstrate. On the other hand isotope nephrography is accepted as a sensitive method to observe renal function especially in regarding to the excretory function of kidney. It was attempted to analysis the findings of urography conjunction with isotope nephrography in 50 cases of unselected patients with invasive carcinoma of cervix through pre and post irradiation follow up studies. Urography was done as a routine procedure and.analysed emphasising changes of collecting systems and ureter condition. Isotope nephrography was carried out by means of $15{\mu}ci\;I^{131}$-Hippuran injected intravenously and the curves were analysed as follows. Parameter were; time of maximum amplitude ($T_{max}$), half time of maximum amplitude ($T\frac{1}{2}$), Kac and Kex value calculated from these two parameters in Tobe's method. The excretion index by Aurell defines the ratio between the maximum activity and the activity measured on the slope of the third phase ten minites after it has reached its maximum. Results: 1. 28.8% had an abnormal IVP suggestive of ureteric involvement before irradiation therapy and the patient of stage III and IV were the great part. 2. 21.7% had abnormal findings of per-irradiation renogram whom showed normal IVP. The other group showed normal IVP which group also showed normal renogram prior irradiation. 3. The more severe the ureteric involvement, the change of excretion index was greater. 4. Even in stage I and II patient, abnormal renogram was revealed in 12 cases (39.4%) among 31 cases. 5. All cases of TAH showed abnormal findings of IVP and renogram. 6. No. definite change of renogram was obtained just after the irradiation therapy (point $A:8000{\sim}9000rads,\;B:5000{\sim}6000rads,\;Co:11000{\sim}13000rads$). Each 3 month follow up study was performed and comparing with preirradiation study which showed significant changes of excretion index of renogram were 42.8% in $6{\sim}9$ month follow-up and 75% in $9{\sim}12$ month, respectively. 7. It seems to be important to observe the parameter Kex and excretion index of renogram to determine early abnormality of kidney excretory function by means of post-irradiation follow up study.
