To elucidate the applicability of the wide latitude X-ray film for radiographic diagnosis and treatment of diseases in small animals, the quality of the wide latitude film was compared with that of the standard latitude film which is commonly used in veterinary clinic. The images of head, neck, thorax, abdomen, extremities and joints were radiographed with the wide latitude and standard latitude film in fourteen dogs. In soft tissues such as abdominal organs, lung, skin, mammary glands, the clearer and higher contrast of the image was observed on the wide latitude film. And these advantages were more apparent in pneumoeritoneography. Therefore. it can be suggested that the wide latitude film is practically useful for the evaluation of the images of soft tissues, and also can be used on hard tissue radiography with the same quality as the standard latitude film.

Adenoid cystic carcinoma is a rare epithelial tumour, and comprises about 1% of all malignant tumours of the oral and maxillofacial region. It is a malignant tumour which may develop in the trachea, bronchus, lungs or mammary glands, in addition to the head and neck region. Occurrences in the head and neck are mostly detected in the major salivary gland, oral cavity, pharynx and paranasal sinus where it presents as a slow growing firm nodular swelling. The aim of the article is to highlight the unique presentation of adenoid cystic carcinoma as a solitary ulcer on the floor of the mouth.

The entire plant of Leptadenia reticulata (Asclepidaceae) is extensively used as lactogen, traditionally, in veterinary practice. The plants of Dregea volubilis and Pentatropis microphylla (Asclepidaceae) are now used as its substitute and sometimes replace the original drug as traditional lactogen. The lactogenic potential of these drugs was studied in rats using, pup weight, weight of mother, parenchyma percentage, secretary rating, estimation of total protein content and glycogen content of mammary glands tissues as assessment parameters. HPTLC profiles of bioactive extracts were also generated to serve the authentification needs. The results of present studies show that P.microphylla forms a better substitute over D. volubilis.

Abnormalities on breast ultrasound (US) images which do not meet the criteria for masses are referred to as nonmass lesions. These features and outcomes have been investigated in several studies conducted by Asian researchers. However, the term "nonmass" is not included in the American College of Radiology (ACR) Breast Imaging Reporting and Data System (BI-RADS) 5th edition for US. According to the Japan Association of Breast and Thyroid Sonology guidelines, breast lesions are divided into mass and nonmass. US findings of nonmass abnormalities are classified into five subtypes: abnormalities of the ducts, hypoechoic areas in the mammary glands, architectural distortion, multiple small cysts, and echogenic foci without a hypoechoic area. These findings can be benign or malignant; however, focal or segmental distributions and presence of calcifications suggest malignancy. Intraductal, invasive ductal, and lobular carcinomas can present as nonmass abnormalities. For the nonmass concept to be included in the next BI-RADS and be widely accepted in clinical practice, standardized terminologies, an interpretation algorithm, and outcome-based evidence are required for both screening and diagnostic US.

유방염은 병원성 미생물들에 의한 유선 내에 염증이 생기는 질환으로, 유방 조직과 우유 내 체세포수 (SCC)와 세균학적 분석이 유방염 진단을 위해서 사용된다. 본 연구에서는 임상형 유방염이 걸린 홀스테인 소의 유선 내로 은 이온(20 ${\mu}g$/ml)을 투입하고, 유방염의 임상 증상의 변화와 우유 내 somatic cell count, 소 혈청 알부민과 lactoferrin 등과 같은 유방염 관련 인자들을 조사하였다. 은 이온의 유선 내 투입은 유방의 부종과 견고함 등의 염증 증상을 완화시켰으며, 우유의 응고와 체세포수를 감소시켰다. 또한, 우유 내 소 혈청 알부민과 lactoferrin의 농도가 은 이온의 투입에 의해 감소되었다, 그러나 임상형 유방염이 걸린 소의 유선 내 은 이온의 투입은 착유된 우유의 양과 혈액 내 백혈구와 적혈구 수를 변화시키지는 않았다. 이러한 결과는 유방염이 걸린 소에 은 이온을 유선 내로 투입 함으로서 염증과 세균의 활성을 감소시킨다는 것을 보여주며, 은 이온을 임상형 유방염의 치료에 적용할 수 있는 가능성을 보여 주는 것이다.

우유 단백질인 ${\gamma}$- 카제인 유전자는 여러 호르몬들에 의해서 임신기간과 비유기기간 동안에 동물의 유선조직에서 발현되는 카제인 유전자 집단의 하나이다. 우유 단백질 유전자의 유도를 조절하는 호르몬에 관한 메커니즘 설명으로 생쥐 ${\gamma}$- 카제인 유전자가 분석되었고 특성을 밝혔다. ${\gamma}$- 카제인 유전자는 박테리오파지 EMBL 3벡터에 삽입된 제놈 도서관으로부터 ${\gamma}$- 카제인 cDNA를 probe로 사용하여 스크린하여 하나의 클론을 얻었다. ${\gamma}$- 카제인 cDNA를 probe는 부분적으로 염기배열을 밝혔으며 ATC 개시 암호와 5'-noncoding 부위를 포함하고 있다. 클론된 제놈 DNA는 제한효소 Sal I에 의해서 ENBL 3벡터로부터 분리 되었다. 3개의 DNA밴드들을 관찰할 수 있었다. 각각의 크기는 28Kb, 14Kb 그리고 9Kb 이다. 따라서 삽입된 DNA의 크기는 대략적으로 23Kb 이다. Southern blot 분석 결과, 클론된 제놈 DNA는 cDNA 5' 발단 부위를 합성한 oilgonucleotides(40 mer)와는 결합되지 않음을 보여주고, 그러나 ${\gamma}$- 카제인 cDNA와는 결합되는 것을 보여 준다. Pormoter 부위를 포함하는 ${\gamma}$- 카제인 제놈 DNA는 cDNA 5' 말단 부위의 합성된 probe에 의해서 생쥐 제놈 도서관으로 부터 스크린하여 현재 29개의 클론을 얻었다.

MicroRNAs (miRNAs) are abundant in bovine milk and milk derived from other livestock, and they have functional roles in infants and in the secretion process of mammary glands. However, few studies have evaluated miRNAs in dairy processes, such as during cheese making and ripening. Thus, we investigated the characteristics of milk-derived miRNAs during the manufacturing and ripening of Camembert cheese as well as the microbiota present using the quantitative reverse transcription polymer chain reaction (RT-qPCR) and 16S rRNA pyrosequencing, respectively. Pyrosequencing showed that the cheese microbiota changed dramatically during cheese processing, including during the pasteurization, starter culture, and ripening stages. Our results indicated that the RNA contents per $200mg/200{\mu}l$ of the sample increased significantly during cheese-making and ripening. The inner cheese fractions had higher RNA contents than the surfaces after 12 and 22 days of ripening in a time-dependent manner (21.9 and 13.2 times higher in the inner and surface fractions than raw milk, respectively). We performed a comparative analysis of the miRNAs in each fraction by RT-qPCR. Large amounts of miRNAs (miR-93, miR-106a, miR-130, miR-155, miR-181a, and miR-223) correlated with immune responses and mammary glands were present in aged cheese, with the exception of miR-223, which was not present on the surface. Considerable amounts of miRNAs were also detected in whey, which is usually disposed of during the cheese-making process. Unexpectedly, there were no significant correlations between immune-related miRNAs and the microbial populations during cheese processing. Taken together, these results show that various functional miRNAs are present in cheese during its manufacture and that they are dramatically increased in amount in ripened Camembert cheese, with differences according to depth.

Purpose: The thyroglossal duct runs from the base of the tongue to the thyroid. Rarely the thyroid completely fails to migrate and results in ectopic thyroid tissue, which can be demonstrated scintigraphically. A 31-year old female patient was referred for thyroid scintigraphy due to protruding mass at the base of the tongue. She was mildly hypothyroid. Te-99m pertechnetate thyroid scan was performed to rule out ectopic thyroid gland. There showed a focal area of intense tracer uptake in sublingual area, suggesting the sublingual thyroid. In addition there noted diffusely increased tracer uptake in both breasts. The patient delivered a baby 6 months prior to the scan and was on breast-feeding. Free Tc-99m pertechnetate physiologically secrets into the salivary glands, the stomach, the gastrointestinal tract, the genitourinary tract and the mammary glands and sodium-iodide symporter plays a role in the accumulation of free Tc-99m pertechnetate. We report simultaneous visualization of lactating breasts and ectopic thyroid gland in the base of the tongue.
