The Tsushima leopard cat, Prionailurus bengalensis euptilurus, a small felid, inhabits only the Tsushima Islands in Japan. Previous studies of the Tsushima leopard cat revealed that natural factors; including sex, reproductive activity, season, and prey distribution and abundance affect leopard cat home range variation and habitat use. In this study, we focused on clarifying how anthropogenic factors influenced home range variation and habitat use of a male Tsushima leopard cat living near a suburban area in January, March, May and September 2005 using radio-tracking. The home range size (100% MCP) of this cat was $0.78\;{\pm}\;0.26\;km^2$ (mean ${\pm}$ SD, n = 4 tracking sessions) across the whole study period. However, the cat did not use all parts of its home range uniformly; rather it used some habitat types selectively. The cat avoided agriculture areas and residential areas in all of the tracking-sessions. On the other hand, the cat showed a weak preference for artificial structures and a strong preference for baiting sites in January and March, while it avoided them in May, and no baiting site was included in its home range in September. These results suggest that anthropogenic factors influenced the ranging patterns and habitat use of the leopard cat living near a suburban area. Artificial structures might provided good resting spaces for the cat in bad weather. When the density of its main prey was low in the winter, the cat tended to rely on artificial prey and had a small home range size.

Objectives : The purpose of this study was to investigate the reproductive effect of Ginseng radix on male mice. Methods : Male C57BL/6J mice were divided into four groups ; normal group (vehicle-treated, n=8), Ginseng radix treatment group (100, 500, 1000 mg/kg, n=8). Ginseng radix extract was treated for 5 weeks. After treatment each group was examined for assessment of sperm count and CatSper protein expression using computer assisted semen analysis (CASA) system and the immunofluorescence. Results : Sperm count of normal and Ginseng radix extract treated group were 287.57 vs. 371.62, 364.83, $343.29{\times}10^6$, respectively. The CatSper3, 4 proteins expression of Ginseng radix treated group were significantly increased than that of normal group. Conclusions : These findings suggest that the Ginseng radix improves male reproductive function by increasing sperm count and CatSper protein expression.

The characteristics of probenecid effect on renal urate excretion in the cat were studied by clearance method and compared with those in the rabbit. In the cat GFR was $3.03{\pm}0.09\;ml/min{\cdot}kg$, and endogenous plasma urate concentration was $1.12{\pm}0.57\;{\mu}g/ml$, which is less than that in the rabbit $(3.33{\pm}0.46\;{\mu}g/ml)$. In the rabbit, $FE_{ur}$ was $1.76{\pm}0.08$ and net urate secretion was observed, while, in the cat $FE_{ur}$ was $0.70{\pm}0.02$ and net reabsorption was observed. In the cat $FE_{ur}$ was dependent on urine flow and independent of plasma urate concentration. In the rabbit $FE_{ur}$ was suppressed by infusion of probenecid $(30\;mg/kg\;-0.6\;mg/kg{\cdot}min)$ into femoral vein. In the cat the same dose of probenecid increased $FE_{ur}$ and concomitantly increased urine flow. Thus, an increase in $FE_{ur}$ by probenecid could be considered to be resulted from a change in urine flow. In the cat infusion of probenecid $(2.5\;mg/kg{\cdot}min)$ into renal artery markedly suppressed $FE_{P\;A\;H}$, but the effects on $FE_{ur}$ and urine flow were similar to those when probenecid was infused into femoral vein. These results indicate that in the cat kidney urate filtered through glomerulus is reabsorbed by a probenecid-insensitive mechanism with no evidence for net secretion.

Purpose: This study was performed to identify climacteric symptoms corresponding to the use of complementary and alternative therapy(CAT) in middle aged women. Method: The subjects of the study were 603women(40-64years) and were chosen by convenient sampling from 1 April to 31 July 2004. The collected data was analyzed using descriptive statics, chi-square, t-test analysis by SPSS/WIN program. Results: 1. It was shown that 63.8% of subjects have utilized one or more types of CAT. 2. It was shown that the most frequently used types are health supplement(40.5%), gold acupuncture(31.2%), acupress(24.7%), hand acupuncture(21.8%) 3. There was significant difference in the using experience CAT by religion(p=.029), job(p=.018), hormone replacement(p=.016), exercise(p=.007), health state(p=.013). 4. There was significant difference in climacteric symptoms(p=.000) corresponding to the using experience of CAT. 5. There was significant difference in climacteric symptoms(p=.028) corresponding to the using experience hand therapy of CAT. Conclusion: We found that middle aged women used CAT more than others populations. Future research examining the determinants of CAT use, incorporating attitudinal and health conditions, as well as clinical efficacy, effectiveness, and health outcome studies of specific CAT therapies are warranted.

Recently, several ICT-based cat studies have produced some successful results, according to academic and industry sources. However, research on the level of simply identifying the cat's condition, such as the behavior and sound classification of cats based on images and sound signals, has yet to be found. In this paper, based on the veterinary scientific knowledge of cats, a practical and academic cat monitoring and disease diagnosis system is proposed to monitor the health status of the cat 24 hours a day by automatically categorizing and analyzing the behavior of the cat with location information using LSTM with a beacon sensor and a raspberry pie that can be built at low cost. Validity of the proposed system is verified through experimentation with cats in actual custody (the accuracy of the cat behavior classification and location identification was 96.3% and 92.7% on average, respectively). Furthermore, a rule-based disease analysis system based on the veterinary knowledge was designed and implemented so that owners can check whether or not the cats have diseases at home (or can be used as an auxiliary tool for diagnosis by a pet veterinarian).

Differential expression of the three chlorophyll afb binding (cab) protein gene (cabl, cab2, and cab3) promoters of Arabidopsis thaliana was studied in tobacco plants transformed with cab-CAT (chloramphenicol acetyltransferase) translational fusions. CAT activity was measured to monitor the activities of the cab promoters. The activity of cabi promoter was higher than the other two in transformed tobacco leaves and also in calli and shoots derived from the leaves. Their activities were organ-specific and were the lowest in roots, medium in stems, and the highest in leaves. The relative activity of cabi promoter in stems comparing to it activity in leaves was, however, much higher than the values of cab2 and cab3. When the cab promoter activity was expressed as CAT activity per unit chlorophyll instead of CAT activity per unit protein, the relative cab] promoter activity (stem/leaf) became almost unity. This result suggests that cab2 and cab3 show photosynthetic organ-specificity but cabl does not. Similar result was obtained in the differentiation process of stems and leaves from shoots derived from the transgenic tobacco leaves.leaves.

A Turkish angora cat with a one-week history of anorexia and vomiting was diagnosed with hepatic lipidosis. During hospitalization and treatment, the cat suddenly showed respiratory-related clinical signs, including coughing and dyspnea, 13 days after initial diagnosis. Due to the poor response to treatment, the patient was euthanized at the owner's request. A postmortem histopathologic examination of the cat's heart showed dilation and wall thinning of the right atrium and ventricle, with fibrofatty infiltration corresponding to an arrhythmogenic right ventricular cardiomyopathy (ARVC). This is a case report of ARVC concurrent with hepatic lipidosis in a cat; both diseases are related to disturbances in lipid metabolism.

The lipid compositions including fatty acid sterol lipid class and the lipid component of the total lipid extracted from the flesh of some fresh water fishes I. e. mandarin cornet cat fish and Korean perch were compared. The levels of total lipid of flesh tissues from the fresh water fishes were high(7.4%) in cat fish but low(1.4-2.2%) in mandarin fish Korean perch and cornet fish. On the contrary the content of unsaponifiable matters found in total lipid was low(2.6%) in cat fish but high(6.0%-6.5%) in mandarin fish Korean perch and cornet fish. Total lipids were mainly composed of triglyceride(74.6-86.5%) as major component in each sample and the other lipid components of total lipid e. g. polar lipid free fatty acids and free sterol were the minor components, The major fatty acids in total lipid of each sample were{{{{ {C }_{16 { }:_{ }0 } }}}}(19.6-29.2%) {{{{ {C }_{16 { }:_{ }1 } }}}}(17.3-30.7%) and {{{{ {C }_{18 { }:_{ }1 } }}}}(16.8-29.2%) and additionally it chiefly consisted of {{{{ {C }_{14 { }:_{ }0 } }}}} and {{{{ {C }_{18 { }:_{ }2 } }}}} Particularly the contents of polyenoic acids in total lipid of cat fish were higher than those of the other fish samples. The level of cholesterol in total lipid was low (8.3mg/g) in cat fish but were high(36.9-59.9mg/g) in mandarin fish Korean perch and cornet fish. The contents of fractionated neutral lipid(NL) were higher than those of polar lipid(PL) in each sample. Particularly phospholipid content in PL was low(6.0%) in cat fish but were high(23.1-36.3%) in mandarin fish Korean perch and cornet fish. Neutral lipids were mainly consisted of triglyceride(84.5-93.4%) as amjor component in each sample and the other lipid components of neutral lipid e, g, free fatty acids and free wterol were exhibited as a minor components, The fatty acid compositon of neutral lipids was very resembled to total lipids. The phospholipid in mandarin cornet and cat-fish were mainly composed of phosphatidyl serine(23.1-49.8%) and phosphatidyl choline(20.8-45.3%) The relatively higher amounts of phosphatidyl serine were observed in mandarine cornet and cat-fist than in Korean perch, But phosphatidyl ethanolamine(42.3%) and phosphatidyl choline (49.9%) were the main phospholipid in Korean perch. The extraordinary high content of phos-phatidyl ethanolamine compared to other fishes was characteristics in phospholipid composition of Korean perch. The major fatty acids in phospholipid of each sample were {{{{ {C }_{16 { }:_{ }0 } }}}} (38.3-46.5%) {{{{ {C}_{18 { }:_{ }0 } }}}}(14.2-21.7) and C16:1(11.6-13.8%) and additionally it chiefly consisted of C18:2, C18:0 and C17:0 The major fatty acids in glycolipid of each sample were C16:0(28.8-40.1%) C18:1(5.4-29.9%) C18:0(5.1-28.9%) and C16:1(8.2-20.1%) and additio-nally it chiefly consisted of C14:0 and C20:1.
