A comprehensive study of 132 Escherichia coli isolates from 150 piglets with colibacillosis included detection of heat-labile enterotoxin, heat-stable enterotoxin, and identification of K88 (F4), K99 (F5), 987P (F6), and F41. Four pili were examined by haemagglutination and slide agglutination test. Heat-labile(LT) and heat-stable(ST) enterotoxin was determined by reverse passive latex agglutination and precipitation test, respectively. Among 132 E coli isolates, 26 had K88 (19.7%), 16 had K99 (12.1%), 3 had 987P (2.3%), and 2 had F41 (1.5%). Three had K88 and K99 (2.3%), 3 had K88 and 987P (2.3%), 2 had K99 and 987P (1.5%), 5 had K99 and F41 (3.8%), and 8 E coli strains had K88, K99 and F41 (6.1%) simultaneously. Among 132 E coli isolates, 5 produced LT only (3.8%), 55 produced heat-stable toxin ST only (41.7%), and 4 produced both LT and ST (3.0%). Three major pathotypes accounted for 27.9% of E coli isolates: $K99^+$ (8.3%), $K88^+ST^+$ (9%) and $K88^+$ (10.6%). Results of this study indicated that piliated enterotoxin-producing E coli was prevalent and was associated with diarrhea in preweaning piglets.

Estrus cycle of cow, season and follicldar stimulating treatment, having an effect on the number of follicle, are investigated for the oocyte recovery rate in ovum pick-up(OPU). The number of follicle aspirated and oocyte collected on the different days of estrus cycle(D 4~5, D 9~10 and D 14~15) were not significantly different among the groups. The higher number of viable oocytes were produced on Jan-May(79.0%) than Jun-Aug(33.3%) by OPU in cow. The number of follicle and aspirated oocyte in cows treated FSH or PMSG combined with bovine somatotropin(bST) were 1.2~1.5 times higher than in cows treated alone follicular stimulating hormone(FSH) or pregnant mare serum gonadotropin(PMSG). In conclusion, OPU can be repeatedly practiced 2 or 3 times in an estrus cycle. In addition, the high environmental temperature is not good for ovarian function of cow and the bST co-treatment with FSH or PMSG is increasing the number of aspiratable follicle.

Objectives The objective of this study was to contribute to the development of pharmacupuncture for obesity treatment by reviewing the studies of pharmacupuncture experimentations and clinical trials. Methods We searched the papers with keywords of 'obesity' and 'pharmacupuncture' in the search site, RISS, Oriental medicine advanced searching integrated system(OASIS), Korean traditional knowledge portal, the society of Korean medicine for obesity research, Korean pharmacupuncture institute, the Korean academy of oriental rehabitation medicine and Korean acupuncture & moxibustion society. Results 1. We reviewed 37 articles searched. 27 articles(73.0%) were animal experimentations, 5 articles(13.5%) were cell experimentations, 4 articles(10.8%) were clinical trials and 1 article(2.7%) was study analysis. 2. The herbs, using for animal experimentations, were atratylodes japonica, coix lachrymajobi, ephedra sinica, crataegus pinnatifida, wild ginseng and etc. Acupucture points were joksamni(ST36), zhongwan(CV12), gansoo(BL18), pungnyung(ST40), umnungchon(SP9), bisu(BL20), gokji (LI11), cheun-chu(ST25) and etc. 3. For cell experimentations, preadipocytes and adipocytes performed on cell cultures with using rats, 3T3-L1 preadipocytes and porcine skin including fat tissue were treated with fel ursi, bovis calculus, ephedrae herba, spirodelae herba, wild ginseng. 4. For clinical trials, Sangsik no.1, Bigiheo, ephedra, green tea and sweet bee venom were injected at the region where a lot of fat like zhongwan(CV12), xiawan(CV10), kwanwon(CV4), cheun-chu(ST25) and thigh. Conclusion Through animal and cell experimentations and clinical trials, the treatment of obesity using local acupuncture therapy was effective. For clinical use, however, it is considered that animal and cell experimentation and clinical trial's connection using one kind of herb and studies about more clinical trials and associated side effects are needed.

In this study, the biological units of elementary school science were classified to the lower categories of Dimensions of Learning out of the 1 st to the 7th National Curriculum using the Dimensions of Learning Project developed by ASCD in USA. Also they were investigated which lower categories of Dimensions of Learning were used to the Curriculum. The results were as follows; First, the average percentages of using the lower categories of Dimensions of learning increased gradually from lower to higher grade regardless of any versions of Curriculum. For example, the percentages of using the lower categories according to grade 3 to 6 were increased by $56.1\%,\;61.4\%.\;67.1\%,\;86.8\%$ in the 7th Curriculum (r = .942). Second, as a result of investigating the percentages of using lower categories of Dimensions of Learning according to the change of curriculum, the average percentages appeared to be $37.9\%,\;42.9\%,\;41.1\%,\;47.6\%,\;47.6\%,\;50.5\%,\;67.9\%$ from the 1st to the 7th National Curriculum, respectively. In addition, the average percentages were increased gradually from the 1st to the 7th National Curriculum (r = .878). Third, the average percentages of using the lower categories of Dimensions of Learning decreased approximately from 1 st to 5th Dimension. The results are considered to be a desirable organization considering the physiological, cognitive development of elementary students.

The species composition and abundance of aquatic insects were investigated by light trap in summer, 2002 at three stations in the Chikuma River, Japan's longest river. A total of 3278 adults/day were collected, the great majority (57.5%) of which were Diptera, followed by Trichoptera (35.4%) and then Ephemeroptera (7.1%). The number of collected aquatic insects and their biomass gradually increased towards downstream, whereas the number of species and species diversity index (H') decreased. 36 species (H'= 4.30) of aquatic insects were collected at St. 1, versus 31 species (H'= 2.81) at St. 3. Moreover, the relative abundance of functional feeding groups changed from St. 1 to St. 3, i.e., 'collectors' increased and 'shredders' decreased.

Purpose : To evaluate the effect of radial head resection on longevity in nonconstrained total elbow arthroplasty, Materials and Methods : The results of 20 cases of radial head replaced Pritchard ERS and 18 cases of radial head excised Kudo elbow was followed for 6 to 16 years, 10.6 years in average. The rate of loosening, osteolysis, radial head subluxation, joint dislocation and valgus deformity were compared between the two groups. Results'There was no exaggerated cubitus valgus in Pritchard ERS group. However there developed one case of delayed subluxation of radial head occurred in 6 years postoperatively, one case of loosening, and one case of sponta- neous fracture of humeral shaft due to osteolysis. In Kudo elbow group,5 cases (27.8%) showed exaggerated valgus deformity with instability. There were one case of loosening and one case of delayed dislocation occurred in a year postoperatively. Conclusion : The most clear feature of Kudo elbow was exaggerated cubitus valgus. However, the ostolysis was developed in both groups and there was no difference in rate of the other complications between the two groups.

Objectives : The aim of this study was to investigate changes of gastric vagal nerve activity and pyloric valve function after execution of combination treatments of both electroacupuncture at Zusanli(ST36) and manual acupuncture at other acupoints in patient with functional dyspepsia. Methods : Bowel sounds of 49 patients (18 male, 31 female) were recorded and their % of bowel sound (%BS) and ratio of dominant frequency (DF) were analyzed. Postprandial %BS was used to indicate the gastric vagal activity after eating. Ratio of postprandial/fasting dominant frequency was used to present the degree of pyloric valve function. According to values of %BS and DF ratio, each patient was classified into normal or abnormal (<6 %BS, hypoactivity: <1 DF ratio, dysfunction) group. For 2 weeks, patients received a treatment consisting of both electroacupuncture stimulation at Zusanli (ST36) and acupuncture at other meridian points. Variation of parameters shifting normal to abnormal or abnormal to normal was observed, and total cure rate was calculated. Results : Total cure rate of %BS was 16%, and that of DF was 37%. Patients who improved to normal value from abnormal or aggravated to abnormal level showed both significant difference in both vagal nerve hypoactivity and pyloric valve dysfunction, respectively. Conclusions : Analysis of bowel sound might be useful to evaluate both gastric vagal nerve activity and pyloric valve function. Combination effects of Zusanli (ST36) electroacupuncture and manual acupuncture of other acupoints showed a bidirectional effect in which their activity and function were in general improved. sometimes from aggravated to abnormal level.

Objective: Percutaneous kyphoplasty using a balloon-catheter is an widely accepted method which achieves the restoration of vertebral height and the correction of kyphotic deformity with little complication in osteoporotic vertebral compression fractures. The authors assess the results of 59 patients who underwent kyphoplasty, and analyze the factors that could affect the prognosis. Methods: From December 2001 to May 2003, fifty-nine patients underwent kyphoplasty. The patients included 49 women and 10 men aged 52-85 years. Average t-score on bone marrow density was -3.58. About 7cc of polymethylmethacrylate(PMMA) was injected into the fractured vertebral body using $Kyphon^{(R)}$ under local anesthesia. The vertical height of all fractured vertebrae was measured both before and after surgery. Outcome data were obtained by comparing pre- and post-operative VAS score and by assessing postoperative satisfaction, drug dependency and activity. Various clinical factors were analyzed to assess the relationship with the outcome. Results: The VAS score improved significantly, and the mean percentage of restored vertebral height was 53%. The mean improvement in kyphosis was $3.6^{\circ}$. Eighty-nine percent of the patients gained excellent or good results. Any of the clinical factors including the interval between fracture and operation, the degree of height loss, the degree of the vertebral height restoration or the correction rate of kyphosis did not affect the clinical results. Conclusion: Kyphoplasty is associated with a statistically significant improvement in pain and function with little complication. The clinical results are not affected by any clinical parameters. Further follow-up study is needed to determine whether the restoration affects the long-term clinical results.

Image-guided localized, water-suppressed in vivo $^1$H MR spectroscopic studies were performed on the patients with brain tumors, acute cerebral infarction and schizophrenia, and dogs. GE Signa 1.5 T whole-body MRI/MRS system using STEAM pulse sequence was used. Proton metabolite ratios relative to creatine (Cr) were obtained using a Marquart algorithm. In vivo $^1$H MR spectra in brain neoplastic tissues revealed the changes of signal intensities of N-acetylaspartate (NAA), choline (Cho) and lactate (Lac) resonances. The present results suggest that the observed metabolite alterations from localized, water-suppressed in vivo $^1$H MR spectroscopy can be useful as an index of brain tumors, cerebral infarction and schizophrenia, and provide good quality metabolic information of cerebral tissue in the field of thanato-chronology.
