This is the report of sacroiliac luxation in a Holstein-Friesian cow, describing the progression of the sacroiliac luxation from the onset of its development with changes in estradiol (E2) and serum chemistry. The high estrogen concentration was assumed to be a predisposing factor of the disease that relaxed the pelvic muscles and a secondary slippery finally caused the sacroiliac luxation. The E2 was present at levels four times higher in the cow with sacroiliac luxation (167 pg/mL) than in normal cows. Above normal levels of creatinine kinase, aspartate aminotransferase, and lactate dehydrogenase were also observed in cow with sacroiliac luxation.

This review summarizes the current trends related to insect as food resources among consumers, industry, and academia. In Western societies, edible insects have a greater potential as animal feed than as human food because of cultural biases associated with harmful insects, although the abundant characteristics of edible insects should benefit human health. Nevertheless, many countries in Asia, Oceania, Africa, and Latin America utilize insects as a major protein source. Using insects can potentially solve problems related to the conventional food-supply chain, including global water, land, and energy deficits. Academic, industry, and government-led efforts have attempted to reduce negative perceptions of insects through developing palatable processing methods, as well as providing descriptions of health benefits and explaining the necessity of reducing reliance on other food sources. Our overview reveals that entomophagy is experiencing a steady increase worldwide, despite its unfamiliarity to the consumers influenced by Western eating habits.

The inhibitory effects of Asparagus cochinchinensis against inflammatory response induced by lipopolysaccharide (LPS), substance P and phthalic anhydride (PA) treatment were recently reported for some cell lines and animal models. To evaluate the hepatotoxicity and nephrotoxicity of A. cochinchinensis toward the livers and kidneys of ICR mice, alterations in related markers including body weight, organ weight, urine composition, liver pathology and kidney pathology were analyzed in male and female ICR mice after oral administration of 150, 300 and 600 mg/kg body weight/day saponin-enriched extract of A. cochinchinensis (SEAC) for 14 days. The saponin, total flavonoid and total phenol levels were found to be 57.2, 88.5 and 102.1 mg/g in SEAC, respectively, and the scavenging activity of SEAC gradually increased in a dose-dependent manner. Moreover, body and organ weight, clinical phenotypes, urine parameters and mice mortality did not differ between the vehicle and SEAC treated group. Furthermore, no significant alterations were measured in alkaline phosphatase (ALP), alanine aminotransferase (ALT), aspartate aminotransferase (AST), lactate dehydrogenase (LDH), blood urea nitrogen (BUN) and the serum creatinine (Cr) in the SEAC treated group relative to the vehicle treated group. Moreover, the specific pathological features induced by most toxic compounds were not observed upon liver and kidney histological analysis. Overall, the results of the present study suggest that SEAC does not induce any specific toxicity in the livers and kidneys of male and female ICR mice at doses of 600 mg/kg body weight/day.

This survey was carried out in order to obtain and apply the basic information on levels of raising skill, recognition of mutual infection between animal and human field of skill training, registration of animal pedigree, mating places, difficulties of raising, channel of marketing, and prospects of raising by socio-ecological status. Data were randomly gathered from 713 peoples, who composed of 398 men and 315 women, from March to August, 2005. As the results, questionnaires were analyzed that relatively 'the level of breeding skill is middle(43.9%)'. The average score for skill level is 1.81$\pm$0.79 when 4 points were used as a full mark. The recognition of mutual infection between human and animal is answered that 'many respondents don't know very well(62.6%)'. The questionnaire answered largely that 'the field of raising skill training is trimming and grooming(29.2%)'. The respondents recognized that 'The pedigree registration of pet is not essential(52.7%)'. The pet breeders answered that 'the mating for reproduction was conducted mainly in pet shops(34.3%)'. The breeders indicated mostly that 'the difficulties of raising were technical skills of raising(53.5%)'. The respondents answered that 'the deal of marketing of animal was mainly achieved through neighbors and close relatives(42.8%)'. The many questionnaires were recognized that 'breeders have a good prospect for the pet industry in the future(51.5%)'.

Food labeling regulations require that the meat species in various meat products are accurately declared to the consumer. Substitution or adulteration of costly meat with a cheaper one is one of the most common problems in the meat industry. In this study, PCR-restriction fragment length polymorphism(RFLP) method of the mitochondrial cytochrome b(mt cyt b) gene has been applied for identification of the origin of six mammalian meat species(beef, port horse, goat, mutton and deer) and three poultry meat species(chicken, turkey and duck) as raw materials for meat products. PCR was used to amplify a variable region of mt cyt b gene. Meat species differentiation was determined by digestion of the amplified products with a 359 bp fragment using HaeIII and HinfI restriction enzymes, which generated species-specific RFLP patterns. This PCR-RFLP DNA marker of mt cyt b gene could be very useful for the accurate and reliable identification and discrimination of animal meat species in routine analysis.

본 연구는 목저은 다음과 같다: 1) 돼지에서 150-kDa temary insulin-like growth faetor(IGF)complex의 한 구성 요소인 acid-labile subunit(ALS) 유전자 intron의 존재 확인. cloning 및 돼지 ALS(porcine ALS; pALS) complementary DNA(cDNA)의 3' 비해독(untranslated) 부위(3' UT) 증폭. cloning, 2) intron-spanning primer pair를 이용한 reverse transcription-polymerase chain reaction(RT-PCR) 방법에 의한 돼지 조직에서의 ALS 유전자 발현 분포 확인 및 3) 돼지 hepatocyte에서의 ALS 유전자 발현 여부 확인. 돼지 genomic DNA를 template로 하여 PCR 방법으로 예상된는 intron 부위를 증폭하고 plasmid vector에 삽입하여 염기서열을 결정한 결과 타 종의 ALS 유전자에서와 같은 위치에 1,371-base pair(bp)의 pALS intron이 존재함을 확인하였다. 역시 본 연구에서 간에서 추출한 RNA를 주형으로 시작하여 3' rapid amplification of cDNA end(3' RACE) 방법으로 147-bp의 3'UT를 합성하고 그 염기성열을 결정하였다. RT-PCR 결과 간은 물론 조사된 모든 돼지의 내장기관(신장, 폐, 비장)과 자성 생식기관(난소, 난관, 자궁) 및 골격근육에서 ALS 유전자가 발현됨이 밝혀졌다. 또한 돼지 간 조직에 대한 in-situ hybridization 결과 hepatocyte에서 ALS 유전자가 발현됨이 확인되었다. 이상의 결과는 ALS가 혈중 IGF의 저정/조절체로서의 주기능 외에 모세혈관 밖에서도 미지의 기능이 있을 기능성을 시사한다.
