Purpose : The purpose of this study was to investigate clinical features of hospitalized infants 28~90 days of age with fever without source and to analyze those of young febrile infants using risk criteria for serious bacterial infection. Methods : The clinical features of 131 infants 28~90 days of age admitted to the Ulsan Dong-Kang General Hospital Pediatric Department because of fever(temperature ${\geq}38^{\circ}C$ rectally) without source, from January 2000 to December 2000, were investigated by retrospective chart review. The clinical features of 131 febrile infants were analyzed using Rochester criteria. Results : Among 131 cases, there were 60 cases(45.8%) of urinary tract infection, 33 cases (25.2%) of aseptic meningitis, 2 cases(1.5%) of bacteremia and 36 cases(27.5%) of no specific diagnosis. Among 131 cases, there were 57 cases(43.5%) in low risk group and 74 cases(56.5%) in not low risk one by Rochester criteria. A significant difference in the incidence of urinary tract infection, aseptic meningitis and no specific diagnosis was not found between both groups. Male to female ratio was 1.8 : 1. Sex ratio between both groups was not significantly different. Most febrile infant were noted in spring(35.1%) and the summer(36.7%). The peak incidence of aseptic meningitis was noted in May and June. The fever subsided mostly within 48~72 hours after administering antimicrobial agents(61.8~83.2%). A significant difference in duration of fever after administering antimicrobial agents was not found between both groups. Conclusion : A selected group of low risk infants 28~90 days of age with fever without source can be managed as outpatients provided that a thorough initial evaluation is performed, that parents can reliably monitor their infant closely at home and that careful follow up can be assured. Because bag collected specimens were more likely to yield indeterminate urine culture result, a suprapubic or catheter obtained urine specimen for culture is a necessary part of the evaluation of all febrile infants 28~90 days of age. The further prospective study on evaluation and management of young febrile infant should be performed in our hospital.

Purpose: To evaluate the diagnositc value of the absolute and relative renal uptake rates on $^{99m}Tc-DMSA$ renal scan of children with febrile UTI. Method: The absolute and relative renal uptake rates of $^{99m}Tc-DMSA$ were checked in 68 children with febrile urinary tract infection (35 with unilateral focal defect; 13 with bilateral focal defect; and 20 with diffuse bilateral defect) and 49 children with afebrile UTI and normal $^{99m}Tc-DMSA$ renal scan as control. Results: The renal absolute uptake rate in the control group were $21.8{\pm}3.9%(right),\;22.2{\pm}3.9%(left),\;and\;44.2{\pm}7.8%(total)$. The absolute uptake rate gradually increased until the age 12 months and then was stationary. In febrile UTI with unilateral focal defect on the $^{99m}Tc-DMSA$ renal scan, both relative and absolute uptake rates were similarly diagnostic ($41.2{\pm}9.7%,\;16.5{\pm}5.4%$ vs $50.0{\pm}2.6%,\;22.0{\pm}3.9%$, p<0.01). In acute pyelonephritis with bilateral focal defect on the $^{99m}Tc-DMSA$ renal scan, the absolute uptake rate was significantly more diagnostic than the relative uptake rate[$17.3{\pm}5.3%$ (right), $17.4{\pm}5.3%\;(left),\;vs\;21.8{\pm}3.9%,\;(right)\;22.2{\pm}3.9%$, (left)% p<0.01]. In febrile UTI with bilateral diffuse defects on the $^{99m}Tc-DMSA$ renal scan, the absolute uptake rate was significantly diagnostic than the relative uptake rate [$18.1{\pm}3.9%\;(right),\;18.4{\pm}3.8%\;(left),\;vs\;21.8{\pm}3.9%,\;(right)\;22.2{\pm}3.9%$(left), p<0.01]. Conclusion: In the $^{99m}Tc-DMSA$ renal scan, the absolute uptake rate was more useful than the relative uptake rate to evaluate bilateral acute pyelonephritis.

Effect of sulfur (S) on utilization efficiency of fresh cassava foliage and cassava hay in dairy cows was evaluated using thirty-two $1^{st}-2^{nd}$ lactation Holstein-Friesian crossbred dairy cows. The experimental treatment was a 2${\times}$2 factorial arrangement in a randomized complete block design (RCBD) using two roughages (rice straw+fresh cassava foliage (FCF) and rice straw+cassava hay (CH)) and two elemental sulfur (S) levels (0.15 and 0.4% S of dry matter (DM)), respectively. Four dietary treatments (FCF+0.15, FCF+0.4, CH+0.15 and CH+0.4) were offered ad libitum in the form of a total mixed ration (TMR) with concentrate to roughage (chopped rice straw+chopped cassava foliage) ratio at 60:40. Fresh cassava foliage or cassava hay resulted in similar dry mater intake, rumen ecology parameters, total tract digestibility, blood chemistry, milk production and composition. However, HCN intake, blood and milk thiocyanate concentration were significantly higher (p<0.01) in cows fed fresh cassava foliage with no sign of potential toxicity. Dry matter intake, body weight changes, molar percentage of propionate in rumen, neutral detergent fiber (NDF) digestibility and nitrogen (N) retention of cows tended to be increased while DM digestibility (65.6, 72.7, 68.6 and 72.1% of total DM intake for the respective treatments), rumen bacteria population (1.4, 1.7, 1.6 and $1.7{\times}10^{11}$ cell/ml for respective treatments), fungal zoospore population (0.4, 0.6, 0.4 and $0.5{\times}10^{6}$ cell/ml for respective treatments), urinary allantoin (25.3, 28.0, 26.3 and 27.6 g/d for respective treatments), microbial N yield (136.0, 154.6, 142.8 and 151.3 g N/d for respective treatments) and milk protein content (3.4, 3.5, 3.2 and 3.5% for respective treatments) were significantly (p<0.05) higher in cows fed on supplemented sulfur at 0.4% of DM in comparison with 0.15% S-supplemented diets. Based on these results, it is concluded that cassava foliage could be used as a portion of roughage for dairy cows and supplementation of S would be nutritionally beneficial.

This study was conducted to evaluate the effects of different levels of crude protein (CP) and protease on nitrogen (N) utilization, nutrient digestibility, and growth performance in growing pigs. A total of six crossbred ([Landrace × Yorkshire] × Duroc) barrows were individually accepted in 1.2 m × 0.7 m × 0.96 m stainless steel metabolism cages. The pigs (average initial body weight of 27.91 ± 1.84 kg) randomly assigned to six diets with six weeks (6 × 6 Latin square design). The experiment was carried out in an environment with a temperature of 23 ± 1.5℃, a relative humidity of 83 ± 2.3% and a wind speed of 0.25 ± 0.03 m/s. The dietary treatments were arranged in a 2 × 3 factorial design with two levels of CP (15.3% or 17.1%) and three levels of protease (0 ppm, 150 ppm, or 300 ppm). The average daily gain and gain to feed ratio (G:F) tended to increase (p = 0.074) with increasing amounts of protease. The low CP level diet reduced (p < 0.050) urinary and fecal N concentrations, the total N excretion in feces, and increased (p < 0.050) N retention. Different protease levels in the diet did not affect (p > 0.05) at N intake, but supplementation of the diets with 300 ppm protease decreased (p < 0.050) the N concentration in urine and feces and tended to increase (p = 0.061) the percentage of N retention retained of the total N intake. The dietary CP level did not affect (p > 0.050) the apparent total tract digestibility (ATTD) of dry matter, digestible energy (DE), and metabolic energy (ME), but diet supplementation with 300 ppm protease showed higher (p < 0.050) ATTD of DE and ME than in the protease-free diet. Therefore, a low protein diet with protease could improve the utilization of nitrogen, thereby reducing the negative effect of N excretion into the environment while maintaining or increasing growth performance compared to a high protein diet.

Intravenous urography (IVU) for urolithiasis is a radiologic examination to diagnosis stone in the ureter path using iodine contrast media, which is radioopacity material. The method includes compression on the upper iliac crest. The compression band prevents outlet of the contrast media through the bladder and enables easier movement to upper urinary tract. This usage depends on the policy of a hospital. Therefore, this study aimed to review and compare the characteristic of progress of contrast media either in compression and non-compression. The retrospective image measurement on 60 cases of intravenous pyelography was conducted at a hospital with the identical type and amount of contrast media as well as criteria for testing. Image measurement was limited to 5 minutes clip, which is optimal for progress of contrast media depending on usage of the compression band. Also, anatomical regions were set as following: "RP" is from renal pyramid to renal pelvis, "PL" is from renal pelvis to lumbar three endplate, and "IU" and "IL" for upper and lower parts from both iliac crests. Analysis has been conducted through the statistical method based on Fisher's Exact Test to find if there are differences of distribution with the anatomical regions with compression or no compression. It has been confirmed that there is no statistical significant difference as the video measurement on 30 cases of compression and non-compression group respectively resulted in P value of 0.580 from left and 0.711 from right (both 0.960). Therefore, it has been concluded that application of a compression band on an intravenous pyelography for urolithiasis patient does not meaningfully affect the progress of contrast media.

Hypoparathyroidism has abnormally decreased secretion of parathyroid hormon which responds to the blood calcium level. Wherease, Pseudohypoparathyroidism has normal activity of thyroid hormon, but end-organs, such as urinary tract and osteoclast, do not respond to parathyroid hormon. The cause of this disease is due to the mutation of Guanine stimulating(Gs) protein regulating Gs gene, which is the receptor to this hormon. Pseudohypoparathyroidism is usually noted before 20 years old on average of 8-9 years old. The clinical features of this disease includes delayed growth and development, round face, obesity, soft tissue calcification, ectopic ossification, shortening of metacarpals and metatarsals by epiphyseal closure in advance of age. The mutation of Gs gene which are found in brain, endocrine organs, and chondrocytes is the cause of those features. Reaction to Glucagon, gonadal hormon, and thyroid stimulating hormon is not expected in both cases. The common dental manifestations include enamel hypoplasia, delayed eruption, agenesis of tooth, hypodontia, dysplastic short roots, widened pulpal space, microdontia, intrapulpal calcification, and malocclusion are also often reported. This case which is diagnosed to Pseudohypoparathyroidism showed short and under-developed root of permanent troth, delayed eruption, and non-eruption of premolars and molars. And morphogenesis imperfecta of first and second premolars were also found.

Teicoplanin, a glycopeptide antibiotic, has potential for use as an alternative to vancomycin in the treatment of gram-positive bacterial infections. However, unlike vancomycin, there is a lack of study on teicoplanin's efficacy and safety and the guideline for its use is not available, yet. The objective of this study was to investigate and evaluate the pattern of teicoplanin usage in a university hospital. A retrospective study was performed on 72 adult patients, who took teicoplanin for 3 continuous days at D. University hospital from 1 January 1999 to 30 June 2000. The microorganisms treated with teicoplanin were methicillin-resistant Staphylocorcus aureus $(69\%)$, coagulase-negative Staphylococci $(12\%)$, Enterococcus $(4\%)$, vancomycin-resistant Enterococci $(2\%)$, Streptococci $(2\%)$, and Bacillus $(1\%)$. The types of infection treated with teicoplanin were surgical wound infection $(58\%)$, lower respiratory infection $(11\%)$, bactremia $(7\%)$, urinary tract infection $(5\%)$, pleural fluid infection $(4\%)$, and peritoneal fluid infection $(2\%)$. The mean duration of teicoplanin usage was 16.5 days and teicoplanin was used with 1.4 other antibiotics, which were aminoglycosides (isepamicin, amikacin, netilmicin, astromicin) or quinolones (ciprofloxacin, tosufloxacin) or the third generation cephalosporin (ceftazidime). Only 24 cases $(28.6\%)$ met with the criteria for the justification of use, and the rest of 60 cases $(71.4\%)$ did not meet the criteria. In 84 cases $(100\%)$, blood culture tests were performed prior to the initial dose of teicoplanin. In 83 cases $(99\%)$, serum creatinine were conducted before the initial doses. In 45 cases $(53.6\%)$, serum creatinine was monitored at least twice weekly. In 55 cases $(65.5\%)$, WBC was tested at least twice weekly. In 84 cases $(100\%)$, body temperature was monitored at least once per nursing shift. In 15 cases out of 56 cases, maximum temperature decreased at least 1 degree within 3 days of teicoplanin use. In 15 case out of 35 cases, WBC values were within the normal range after treatment. In 23 cases $(27.4\%)$, dosage regimen was appropriate. Drug-related adverse effects were reported in 13 cases. Nephrotoxicity (progressively increasing SCr. or sustained SCr increase of $\geq$0.5 mg/dl from baseline) was noted in five cases. Neutropenia (absolute neutrophil count <1,500 $cells/mm^3$) was noted in one case and eosinophilia (total eosinophil count >350 $cells/mm^3$) was noted in seven cases. A more strict control on use of teicoplanin is required, considering that teicoplanin is categorized as one of restricted antibiotics.

Objectives: Selaginella bryopteris L. (family: Selaginaceae), is often used in traditional Indian systems of medicine for the prevention and cure of several disorders and for the treatment of patient with spermatorrhoea, venereal disease, constipation, colitis, urinary tract infections, fever, epilepsy, leucorrhoea, beri-beri and cancer. It is also used as a strength tonic. This study aimed to evaluate the mechanisms underlying the anti-inflammatory effects of topically administered aqueous, polar and non-polar methanolic fractions ($10mg/20{\mu}L$) of Selaginella bryopteris. Methods: An acute oral toxicity study of Selaginella bryopteris at doses from 250 to 2,000 mg/kg body weight (bw) was performed. Aqueous, polar and non-polar methanolic extracts ($10mg/20{\mu}L$) applied topically for 5 days were evaluated for their anti-inflammatory effects against 12-tetra-O-decanoyl phorbol acetate (TPA)- induced inflammation by using the redness in the ear, the ear's weight (edema), oxidative stress parameters, such as lipid-peroxide (LPO) and nitric oxide (NO), and the pro-inflammatory cytokines involved in inflammation, such as tumour necrosis factor $(TNF)-{\alpha}$, interleukin $(IL)-1{\beta}$ and IL-6. Indomethacine ($0.5mg/20{\mu}L$) was used for the positive control. Results: Selaginella bryopteris produced no mortalities when administered orally at doses from 250 to 2,000 mg/kg bw. Topical treatment with the non-polar methanolic fraction ($10mg/20{\mu}L$) significantly suppressed redness ($2.4{\pm}0.5$) and edema ($30.4{\pm}1$) and effectively reduced the LPO level ($32.3{\pm}3.3$). The NO level was ($8.07{\pm}0.55$), and the $TNF-{\alpha}$, $IL-1{\beta}$, and IL-6 levels were decreased to $69.6{\pm}15.5$, $7.7{\pm}4.8$ and $82.6{\pm}5.9$, respectively. Conclusion: This study demonstrated for the first time the mechanisms underlying the anti-inflammatory effect of medicinal plants like Selaginella bryopteris and quantified the pharmacological interactions between them. The present study showed this herbal product to be a promising anti-inflammatory phytomedicine for the treatment of patients with inflammatory skin diseases.

Objectives : The objective of this study was to assess whether there were sex differences in stroke types, risk factors, warning signs, and stroke complications among patients with first-ever stroke. Methods : Six-hundred seventy six patients with first-ever stroke were recruited at the Department Cardiovascular and Neurologic Diseases (Stroke center) of KyungHee University Oriental Hospital, DongGuk University International Hospital, and Kyungwon University In-cheon Oriental Medical Hospital from September 2005 to June 2007. Patients were hospitalized within 28 days after the onset of stroke. We investigated their stroke types, ischemic stroke subtypes by TOAST classification, risk factors, warning signs, stroke complications, general characteristics such as age, sex, etc. Results : Overall, 347 patients were male and 279 female. Compared with males, female patients were significantly older (mean age 67.3${\pm}$1.1 versus 62.4${\pm}$1.6 years) (P=0.000). We did not find significant sex differences in stroke types or ischemic stroke subtypes by TOAST classification. History of hypertension was significantly more frequent in female than male patients (P=0.000). Among stroke complications, urinary tract infection was significantly more frequent in female than male patients (P=0.003). Among warning signs, blepharospasm was significantly more frequent in female than male patients (P=0.006). Conclusions : Knowledge of sex differences of stroke patients can help us gain better insights on the characteristics of stroke patients. We need further and larger scale research to acquire more concrete conclusions on this theme.

Differentiating the various causes of hydronephrosis from that of obstruction can be very difficult. The decision-making process for those instances of urinary tract dilatation that require surgical correction and those that do not is based in part on the findings of diuresis renography. The methodology for performing this test has differed among nuclear medicine practitioners and the surgical findings are occasionally discrepant from the diuretic renogram interpretation. Consequently we made an automatic computer software program that calculates the slope of the response curve. The quantitative indices, such as the injection and response t1/2 by linear-fitting and monoexponential-fitting, were compared with the visual assessment of the diuretic cinerenography and clinical outcome in 50 children (62 kidneys) with ureteropelvic junction obstruction. Pooled diuresis renogram data indicated that: (1) Visual evaluation of the diuretic cinerenography is a sensitive (87%, 54/62) tool to differentiate obstruction in suspected ureteropelvic junction obstruction. (2) The cut-off value (maximum washout t1/2 with non-obstruction) of injection and response t1/2 by linear-fitting were 40 min. (3) The sensitivity and specificity using injection and response t1/2 by linear-fitting for obstruction were 89%(23/26) and 100%(30/30), respectively. (4) Response t1/2 as well as injection t1/2 by monoexponential-fitting do not stratify children with possible ureteropelivic junction obstruction. In conclusion, quantitative assessment of diuretic renography as well as visual assessment of diuretic cinerenography correlate well with surgical and clinical outcome of suspected ureteropelvic junction obstruction.
