Background : The cun measurement System, an essential and convenient method in locating acupoints, has been widely used in the practice of acupuncture. However, traditional cun measurement has been criticized for its lack of reliability. Objectives : The purposes of this study are to determine if one cun measured by the directional methods have a consistency with that of proportional methods and to investigate which factors are related with these differences, especially in forearm. Methods : The distance between the elbow crease and the wrist crease of forearm was compared to a reference value of one cun obtained by the directional method. In this method, one cun is one third of the distance between index finger and Small finger of a subject, measured at proximal interphalangeal joint. In addition, to investigate the factors influencing the differences between these two methods, we measured the height and body weight and calculated body mass index (BMI). Finally we analyzed the factors correlated with these lengths by linear regression test. Results : The results showed that one cun obtained by the directional methods were significantly different from one cun by the proportional methods in forearm. It was demonstrated that the length acquired with the directional method was more correlated with body weight and body mass index, while the length obtained by the proportional method was more correlated with the height.

Ozone is very effective in acute and chronic viral disease as a virucidal agent and in improving the general health of the animals. The effects of ozonized water supply against Cryptosporidium baileyi was studied in 2-day-old chicken. After oral inoculation of chicken with 1×10^6 oocysts, ozonized water(0.5ppm) and tap water were supplied to experimental and control group, respectively. The prepatent period of both group was 6 days postinoculation(PI). The patent period of experimental group was shorter(6-18 days) than that of control group(6-22 days). The number of oocysts in the feces were maximum on days 11 PI, indicating 1.99×10^6 oocysts/experimental chicken and 6.00×10^6 oocysts/control chicken. The number of discharged oocysts during experimental period was higher in control group than that of experimental group. In the view of febric bursa sections on 7 days PI, the number of endogenous development of C baileyi was smaller in experimental group that in control group. This results indicate that the autoinfected sporozoite were damaged by ozone. The ozonized water supply to chickens is alleviation cryptosporidiosis.

Two-day old male chickens(DEKALB-Warren, Sex-Sal-Link) were inoculated orally with 2×10^6 oocysts of Cryptosporidium bailyei. Age-matched birds served as controls. A small number of oocysts were first recognized in the feces of chicks on day 3 post inoculation(PI). The OPD for the chickens increased with the lapse of days, reached a peak on day 9 PI, decreased rapidly thereafter, and became negative on days 33 PI. The protozoa had a prepatent period of 2 day and patent period of 3-32 days. On day 10 PI, infections were very heavy, in fact, there was a vitural monolayer of parasites in the microvillus region of the bursa of Fabricius(BF). Histopathological lesions in BF were characterized by severe eosinophilic infiltrates under the epithelium, loss of FAE and epithelium. The eosinophilic infiltrantes were detected in the follicles on day 15 PI. On days 27 PI, follicles were degenerated and necrosised. Mast cells were recognized in the epithelium on day 10 PI, reached a peak on day 43 PI and then rapidly decreased. Location of mast cell was matched with the region of parasited epithelium. Although the cryprosporidia was not detected in the epithelium of BF on day 59 PI, the mucosal change persisted accompanied by hyperplasia and metaplasia. The follicles were normally recovered or partially necrosised on day 59 PI.

For the endurance test, it is necessary to test the portable electric tools under the same condition as the actual operation condition. It is also essential that the test equipment is convenient to fix the tool. Those are necessary to control the loaded torque and to acquire and analyze the test data with a computer. In this study, we have developed an endurance test equipment for portable electric tools, where a hydraulic control system with a proportional relief valve was applied to control the load for the test. The developed test equipment used an industrial hydraulic pump as a load supplier to ensure a firm endurance of the test equipment itself. The data acquisition system has been automated by composing with a personal computer and RS-232C communication nets. This test equipment reduced the manhour for the test and also improved the reliability of the tested data which were measured and graphed.

We developed a new structure water cover which can minimize the noise produced by the falling water drops. And checked the noise reduction for each model of mist-makers adopting 16mm, 20mm, 25mm ceramic discs. We can remove the noise spikes produced by the falling drops. The measured noise with new water covers are 22.60.6dB for 16mm ceramic disc mist-maker, 26.40.7dB for 20mm ceramic disc mist-maker, and 30.30.9dB for 25mm ceramic disc mist-maker. These noise levels are acceptable for home usage.

Background: Thioredoxin peroxidase(TPX) is a kind of recently discovered antioxidant enzyme which react as rapid hydrogen ion donor for the removal of hydroperoxide. The action and distribution of the TPX was poorly understood in the human diseases. This experiments were designed for the study about the distribution of the TPX in the chronic granulomatous inflammation and about the correlation between the expression of TPX and the site of inflammation, histological activities of tuberculous inflammation or existence of mycobacterium in the inflammatory foci. Methods: The immunohistochemical stains were performed for the localization of the TPX-2 in the epithelioid cells, giant cells and lymphocytes in the chronic granulomatous inflammation. The tissue sections were obtained from the paraffin blocks of the 54 cases of tuberculosis (lung 21 cases, lymph node 12 cases, bone and soft tissue 12 cases, kidney 9 cases; active 33 cases, inactive 21 cases by the histologic classification; presence of mycobacterium 15 cases, no mycobacterium 39 cases by PCR reaction). Results: The expression of TPX-2 was 16.7% in the giant cells, 27.8% in the epithelioid cells and 100% in the lymphocytes of tuberculous inflammations. The expression of TPX-2 in the giant cells and epithelioid cells of the tuberculosis were 28.6% and 57.1% of the pulmonary tuberculosis; 33.3% in each cells of the renal tuberculosis; 0% in each cells of the lymph node or bone and soft tissue tuberculosis. The expression of TPX-2 in the giant cells and epithelioid cells were 9.1% in each cells of the active tuberculosis and were 28.6% and 57.1% in each cells of the inactive tuberculosis by histologic classification. The expression of TPX-2 in the giant cells and epithelioid cells was 40% in each cells of tuberculosis which mycobacteria were detected and the expression of TPX-2 was 7.7% and 23.1% in each cells which mycobacteria were not detected by PCR reaction in the paraffin embedded tissue. Conclusions: The above results were summarized that the TPX-2 in the giant cells and epithelioid cells were more frequently expressed in the inactive tuberculosis than in the active tuberculosis. These results suggest that the TPX-2 is a kind of regulating or suppressing factors in the activity of the tuberculosis.

In order to characterize pharmacokinetic profiles according to route of a new enrofloxacin salt form (Enrotil®), it was given to 4 healthy pigs via oral (p.o.), intramuscular (i.m.) or intravenous (i.v.) administrations at a dose rate of 5 ㎎/㎏ body weight. Enrofloxacin (ENFX) in serum was detected by bioassay using E. coli BE1186 as a test organism. The biological elimination half-lives (t_(1/2)(β)) of ENFX were 6.76±0.99 h (i.v.), 7.16±2.30 h (i.m.) and 11.45±3.90 h (p.o.), Volume of distribution (Vd) of enrofloxacin was 2.20±0.31 L/㎏ (i.v.), 2.52±0.60 L/㎏ (i.m.) and 1.88±0.33 L/㎏ (i.m.). Mean residence time (MRT) was 8.77±1.26 h after i.v. injection and the maximal concentration time (Tmax) following p.o. and i.m. administration was 0.76±0.09 h and 0.60±0.12 h, indicating a rapid absorption from these routes. Bioavailibility (F) was calculated as 64.1% for p.o. administration and 59.71% for i.m. injections. In summary, the newly formulated enrofloxacin salt form has shown a high water solubility, rapid absorption and large tissue distribution, suggesting a potential antibacterials for oral application on a large scale in veterinary sectors.
