Glandulla mammae is a secondary sexual characteristic. The composition and structure of the mammary gland depends on the functional state of the gland and is affected by hormones. The mammary gland reaches its full development during gestation and it becomes functional and secretory upon delivery. Lactocytes of the mammary gland may be squamous in shape, low or high prismatic, depending on the phase of the glandular cycle. Lactocytes are affected by LTH hormones due to which they are called prolactin. The function of the mammary gland is also affected by STH, and indirectly by TTH. Examined material was taken from Central Bosnia Canton, under field conditions of veterinary practice. The assay of histological features of the mammary gland of Dubska pramenka was conducted during the dry period as well as during lactation. The total number of animals was 16, eight (8) during the dry period and eight (8) during lactation period. Following the development of histological preparations, we conducted a descriptive overview - interpretation of the histological structures. The study of histological preparations of the mammary gland of Dubska pramenka during the dry period and lactation shows that the parenchyma is well developed, more or less, with reduced intersticium. Histological appereance of the lactocytes resembles that of the perifollicular tissue, the presence of different cells is higher during the lactation - the onset of glandural cycle. Well-developed lactiferous ducts with cavity, with or without secretion, but with preserved epithelium are the characteristics of both periods. The glandural tissue is well-developed and the secretion was present regardless of the examination period.

Success in cattle breeding is one of the most important goals in livestock farming and it requires particular attention when it is about securing unobstructed reproduction. Final goal in cattle breeding is to produce one live calf per year, which will likewise enhance milk production through successful pregnancy. The aim of our research was to monitor uterine involution speed with aid of ultrasound device and make records when cows are ready to be inseminated again, which cows need more time to complete involution and how many cows will have uterine disorders and require therapy. The experiment was carried out from October 2009 until the end of January 2010. In our experiment 50 cows were included and 412 transrectal ultrasound examinations were performed. Cows were transrectally examined, starting from 6th day postpartum until 52 days postpartum. Speed of uterine involution has been monitored through decrease of uterine horn diameter and wall thickness. Cows with normal puerperium have completed involution in the period from 38 - 45 days postpartum, while those with abnormal puerperium needed more time to complete it or required therapy of disturbed uterine status. In total 48% of cows had normal uterine involution, 52% of cows had some abnormalities in involution and 10% of cows in experiment required therapy. With continuous monitoring of reproductive tract in cattle with ultrasound it is possible to timely detect right time for first insemination postpartum, decrease period of open days or to detect abnormalities in uterine health status and treat it.

Malignant mesothelioma is the most significant pleural tumour and it can be divided into three types: epithelial, sarcomatoid and biphasic mesothelioma. The most significant clinical manifestation of this tumour is pleural effusion. This paper was aimed at determining the role of cytological evaluation of pleural fluid in the diagnosis of malignant mesothelioma. This retrospective study included 33 medical records of patients with pleural malignant mesothelioma referred to the Institute for Lung Diseases of Vojvodina, in Sremska Kamenica in the period from 2004 to 2009. In 24 out of 33 patients, x-rays confirmed pleural effusion, thoracentesis was performed and specimens of effusion were cytologically examined at the Department of Pathology of the Institute for Lung Diseases of Vojvodina. Forty-nine cytological examinations were done. Only 2 of the first specimens were positive for malignant cells and 6 were suspicious. In repeated cytological examinations, 5 out of 6 initially suspicious specimens were positive for malignant cells, and the remaining 1 was negative. To sum up, 7 of 49 cytological examinations were positive and the sensitivity of our cytological study for the diagnosis of malignancy was 29%. Due to the low sensitivity of the cytological examinations, it has been recommended to perform biopsy of the pleura for definitive diagnosis in every patient with clinical symptoms and suspicious radiography.

This paper presents analyses of the texts published in the Composer Speaks section in the New Sound magazine, on the occasion of the twentieth anniversary of its continual publishing. It sums up the achieved results, and classifies the collected materials, with special emphasis on methodology issues concerning the status of the interview as a scientific method, indicating its importance in musicological research. The most significant results are viewed from this perspective, drawing attention to the value of the contributions achieved in the research of Serbian music and the development of Serbian musicology.

AIM The aim of this research was to examine the correlation between lipid profile and bone density in postmenopausal and premenopausal women. MATERIAL AND METHODS This research covered 53 subjects who were in postmenopause and 30 subjects who had regular menstruation, older than 45. RESULTS AND DISCUSSION The postmenopausal subjects have lower bone density of the lumbar spine, if triglyceride levels were higher (p = 0.030) and VLDL is higher (p = 0.032). In subjects with regular menstruation, the density of the neck of the femur was greater if the cholesterol values were higher (p = 0.002) and the density of the lumbar spine was greater where the levels of triglycerides (p = 0.002) and of ApoB (p = 0.026) were higher. In subjects in postmenopause there was a correlation between the density of the lumbar spine (p = 0.04) and the density of the neck of the femur (p = 0.008) with the length of menopause. The effect of lipid profile on bone density differs in women with regular menstruation and in postmenopausal women. The triglyceride levels in postmenopausal women contribute to a reduction in bone density, whilst the effect on bone density in women with regular menstruation is reversed, which indicates that the lipid profile is not an isolated factor affecting bone density, but that other factors, such as oestrogen levels and the length of post-menopause, have a significant effect on bone density.
