Protection of the mammary gland against mastitis-causing pathogens is mediated by many factors in the<br />gland and blood circulation. The professional phagocytic cells of bovine udder, polymorphonuclear<br />neutrophils (PMN) and macrophages, comprise the first line of defense against invading mastitis pathogens.<br />Most researchers now accept that the PMN is a key factor in the cows’ defense against intramammary<br />infections. The PMN are the only leukocytes in the milk compartment that are capable of producing large<br />amounts of reactive oxygen species (ROS) to kill phagocytosed bacteria. In this review, the role of PMN<br />function as an effective defense against intramammary pathogens in dairy cows and physiopathological<br />influencing factors on blood and milk PMN functions are discussed. Apart from playing a crucial role in the<br />first line of defense mechanism, the PMN can also, indirectly, interfere with the complex interactions of<br />second line of defense against pathogens. To minimize mammary tissue damage caused by bacterial toxins<br />and oxidative products released by PMN, elimination of invading bacteria should proceed quickly. This can<br />provide balance among inflammation reactions, bactericidal activity and tissue damage. The good balance<br />between host-pathogen interactions might be affected by the physiological (e.g., stage and number of<br />lactation) and pathological (e.g., local-systemic effect of mastitis) status of dairy cows. Hormones,<br />metabolites and acute phase proteins also influence PMN functions, thereby affecting the outcome of<br />mastitis. This is especially the case around parturition. PMN function in healthy cows after parturition is<br />highly heritable and has been related to the cow’s susceptibility to clinical mastitis. Despite advances in<br />veterinary science, nutrition and molecular biology, mastitis is still a very big problem in high yielding dairy<br />cows. The long-term and fundamental solution for mastitis affecting high yielding dairy cows is to strengthen<br />cows’ immune systems by means of attainable physio-immunological approaches. This requires a<br />comprehensive study on the immunophysiological alterations throughout lactation and during mastitis. This<br />review focuses on some factors affecting PMN functions during the lactation cycle and mastitis in high<br />yielding dairy cows.

This study was conducted to evaluate the effects of maternal diabetes on fetal spinal structure, especially<br />in brachial enlargement. Sixteen adult female rats were divided into two groups. Diabetes was induced in one group by alloxan agent. Both groups became pregnant by natural matting. On days 7, 14, 21 and 28 after birth, the brachial enlargement of the spinal cord was collected from offspring of all rats and the weight of neonates was measured. Various histological parameters were determined using histological techniques. The results revealed a significant decrease in transverse spinal diameter and number of neurons of gray matter and an increase in vertical spinal diameter in spinal cord of offspring of diabetic mothers (ODM) as compared with the control group. The body weight of ODM was significantly more than that of the control group (P<0.05). Maternal hyperglycemia exhibited deleterious effects on spinal cord, especially brachial<br />enlargement during fetal life which remained persistent during postneonatal period.

Interferon gamma (IFN-γ) is one of the key cytokines in defining T helper 1 lymphocyte immune<br />responses. In this study, the bovine IFN-γ gene was cloned from spleen tissue RNA using the reverse<br />transcription-polymerase chain reaction (RT-PCR). IFN-γ cDNA was sub-cloned and expressed in<br />mammalian expression plasmid (pcDNA3.1(+)) under the control of the human cytomegalovirus (CMV)<br />promoter. The predicted amino acid (aa) sequence of bovine IFN-γ compared with corresponding known<br />sequence from bovine (Bos taurus) was 100% identity and with ovine, caprine, camel, lama, equine, canine,<br />feline, human, mice and chicken cytokine was 95, 95, 86, 83, 77, 75, 75, 61, 44 and 35%, respectively. Invitro expression of recombinant bovine IFN-γ (rBoIFN-γ) and secretion to culture medium was confirmed by ELISA test. Maximum expression of rBoIFN-γ occurred at 96 and 144 h after transfection in COS-7 cells.<br />These results showed that pcDNA3.1 expression vector and COS-7 cells transfected by diethylaminoethyl<br />(DEAE)-dextran allowed the high level expression of bovine IFN-γ gene and the release of protein in<br />supernatant of cell culture.

Ovine pulmonary adenocarcinoma (OPA) is a contagious and transmissible lung cancer of sheep<br />resembling human bronchiolo-alveolar carcinoma. In the present study, lungs of 9400 sheep slaughtered in<br />Fars province, Iran were examined morphopathologically. The OPA was diagnosed in the lungs of 21<br />(0.22%) out of 9400 sheep. Frequency of involvement of different lobes in the affected lungs was included<br />apical lobe (62%), cardiac lobe (33%), middle lobe (33%), diaphragmatic lobe (62%) and accessory lobe<br />(5%). In 12 sheep, the classical form observed as firm, white to grayish coalescing masses mostly in the<br />cranio-ventral lobes associated with wet cut surface and frothy fluid in the airways. In 9 sheep, atypical<br />lesions observed as small clearly demarcated nodules mostly in diaphragmatic lobes associated with dry cut<br />surface and minor fluid in the airways. Histopathological changes were almost similar in the two forms. They<br />consisted of an acinar or papillary growth of neoplastic cells in the alveoli and polypoid proliferation of<br />bronchiolar epithelium. There were variable amounts of connective tissue, myxomatous foci and infiltration<br />of lymphocytes and plasma cells in the interstitial tissue of the affected alveoli. No metastatic lesion was<br />observed in the lymph nodes. The findings of this study show that atypical and classical forms represent<br />different stages or manifestations of a single disease spectrum.

An in vitro experiment was conducted to determine the effect of supplemental non-fiber carbohydrate<br />(NFC) on the disappearance kinetics of cellulose (Ce) by mixed ruminal microorganisms. Non-supplemented<br />or NFC supplemented cellulose (467 mg NFC/g cellulose as sucrose (CeSu) or starch (CeSt) or a 1:1 mixture<br />of sucrose + starch (CeSuSt)) were incubated for 24, 48, and 96 h at 39°C. After each incubation time, pH,<br />ammonia-N concentration and cellulose disappearance were measured. The disappearance kinetics rate of all samples was determined using first order exponential model of D(t) = D(i).exp (-k. time) + I; where D(t) is potentially digestible fraction; D(i) is potentially digestible residues; k is digestion rate of cellulose (h-1) and I is indigestible fraction. In this experiment, inclusion of NFC to the rumen fluid medium resulted in a<br />significant depression (P<0.01) in the extent of cellulose disappearance. The disappearance rate constant of<br />cellulose was significantly higher (P<0.05) in non-supplemented samples as compared with those treatments<br />containing NFC. The indigestible fraction of cellulose was significantly higher (P<0.05) for treatments<br />containing sucrose or sucrose + starch as the source of supplemental NFC as compared with nonsupplemented cellulose. However, when starch was added, the indigestible fraction of cellulose was similar to those of non-supplemented samples. The inclusion of NFC resulted in a significant reduction (P<0.01) in pH of the medium, but had no significant effect (P>0.05) on ammonia-N concentration.

Developing a culture system for preantral follicles has important biotechnological implications due to the <br />potential to produce a large number of oocytes for embryo production and transfer. To accomplish this goal, <br />the present study was aimed to culture preantral follicles in the presence of different media, sera and FSH <br />concentrations. Six-week-old preantral follicles (95 ± 5 µm) were cultured in North Carolina State University <br />medium 23 (NCSU23), tissue culture medium 199 (TCM199) and leibovitz-15 medium (L-15) for 6 days. <br />Tissue culture medium 199 showed a significant increase inthe follicle diameter (115 µm), survival (39%), <br />oocyte maturation (32%) and germinal vesicle breakdown (GVBD) (29%) rates as compared to L-15 and <br />NCSU23 (P(P(PGS), embryonic stem cell fetal calf serum (ESFCS) and hypogonadal mouse serum (hpgMS), the 5% FCS showed increased follicle diameter (134 µm), survival (52%), oocyte maturation (49%) and GVBD (45%) as compared to control and other types of sera used (Pshowed a significant increase in follicle diameter (197 µm), survival (96%), oocyte maturation (91%) and GVBD (67%: PFSH and 5% FCS, is appropriate for the optimal in vitrogrowth of Syrian mice preantral follicles and enclosed oocytes.

Two batches of frankfurters containing about 55% chicken meat with two different oils (including canola <br />and soybean) were manufactured. Batch 1 included canola oil and Batch 2 included soybean oil in the <br />products. Various analyses were performed to detect the lipid changes of both batches during storage. Fatty <br />acid composition analysis using gas chromatography showed little change in the fatty acids of either batch <br />over time. From a nutritional viewpoint, Batch 1 was more acceptable over time than Batch 2. Chemical <br />analysis included oxidation reactions, such as peroxide and TBA (Thiobarbituric acid) value and free fatty <br />acid analysis. Each chemical experiment had different trends at each time,but both batches had values lower <br />than the maximum levels at all times. With regard to microbial analysis, psychrotrophic bacteria in both <br />batches showed a decreasing order until day 30, and then growth increased. In Batch 1, a significant <br />difference was observed only on day 1, but the differenceswere more significant in Batch 2, and there were <br />significant differences on days 15, 30 and 45. Also, Lactobacilluscounts were not significant after the <br />cooking process until the end of storage (growth was not detectable after the cooking process). At the end of <br />storage, we concluded that Batch 1 had a higher quality and storage stability than Batch 2 and canola oil <br />could be a good substitution for soybean oil in meat products. The data were analyzed with GLM (repeated <br />measures). Differences were reported as significant at P<0.05. Also, the statistical software was SPSS ver. <br />11.5.

The gross and microscopic anatomy of the molar salivary gland of the domestic cat was studied. In this <br />research, five pair of molar glandsfrom five male adult cats were used. In cat, the molar gland was elongated rectangle shape and was located obliquely in the submucosal fossa of the inferior lip, near the oral commissure. The dorsal border of the molar gland was attached to the masseter muscle and posterior facial nerve. The ventral border was located in the angle of the anterior and transverse facial veins near the buccal part of the buccinator muscle. The caudal end of the gland neighboring the anterior facial vein and cranial end was close to the transverse jugular vein. The meanlength and width of the left gland were 11.5 ± 0.3 mm and 3.4 ± 0.3 mm, respectively. The mean length and width of the right gland were 9.2 ± 0.8 mm and 4.1 ± 0.8 mm, respectively. The mean length of the left gland was larger than the right and the difference was significant (P<0.001). In the histological findings the molar gland was surrounded with a dens irregular connective tissue capsule. The septa of the connective tissue from the capsule extended into the gland, dividing the organ into lobes and lobules. The secretory cells made up seromucous units and the mucous cells were predominant. The cells were arranged as compound tubuloacinar type. Most of the tubular units were long and branched, and there were no intercalated or striated ducts.

Fasciolosis is a cosmopolitan parasitic disease with considerable economic and public health importance. <br />Fasciola hepaticais the major cause of fasciolosis in man and domestic animals. Although remarkable <br />research works have been done around the optimum temperature and time required for miracidial <br />development, little is known aboutthe exact susceptibility of Fasciola hepaticaeggs to high temperatures. In <br />the present study, Fasciola hepaticaeggs were initially incubated at 40°C, 45°C, and 50°C for various times <br />(1, 2, 3, 4 and 5 h), followed by incubation at 28°C for 16 days. Miracidial formation was subsequently <br />investigated on the 16th day of incubation. Even though the rate of miracidial formation in the control group <br />was 52%, in the eggs incubated at 40°C for 1, 3, and 5 h, the miracidial formations were 51.4%, 42.4% and <br />39.9%, respectively, and these values in the group incubated at 45°C were 46%, 42.5% and 33.7%, as well. <br />However, in the case of incubation at 50°C for 1, 2, 3, 4 and 5 h, these values were recorded as 1.96%, <br />0.57%, 0.07%, 0.00% and 0.00%, respectively. The results indicated that the eggs were susceptible to high <br />temperatures and incubation of the eggs at 50°C for 4 h was enough to significantly inactivate the eggs and <br />prevent miracidial formation (P<0.001). However, using the livestock faeces as fertilizer in many rural areas <br />may lead to the contamination of pasture. According to the findings of this study, in the areas with a high <br />prevalence rate of Fasciola hepatica, manure storage for a sufficient time or heating the livestock manure <br />before use as fertilizer is strongly recommended.

Abattoir survey was carried out to determine the prevalence of gastrointestinal helminths and the <br />seasonal fluctuations in intestinal worm burdens and faecal worm egg counts of camel in Khorasan Razavi <br />province in the northeast of Iran. A total of 306 dromedaries (Camelus dromedarius) in the Mashhad abattoir, in the northeast of Iran and the capital of Khorasanprovince were examined between October 2007 and September 2008. By coproscopy examinations, 75.1% ofdromedaries were found to be harboring different types of nematod eggs. Faecal flotation revealed the presence of Nematodirus, Strongyloides, Trishuris, Marshallagia, stongyle type nematode eggs. In addition, gastrointestinaltracts of 50 camels slaughtered in the Mashhad abattoir were used for identification and count of helminths. Postmortem examinations revealed that the prevalence of helminths were Trichostrongylus probolurus(64%), Trichuris globulosa(40%), Camelostrongylus mentulatus(38%), T. colubriformis(34%), Stilesia globipunctata (30%), Nematodirella dromedarii(22%), Haemonchus longistipes (18%), Nematodirus oiratianus(16%), Cooperia oncophora (16%), Trichuris barbetonensis(10%), Parabronema skrjabini(10%), Nematodirella cameli(10%), Marshallagia marshalli(4%), Teladorsagia circumcincta (4%), Moniezia benedeni(3%), Moniezia expansa (3%) andTrichostrongylus vitrinus(2%). Nematodirella dromedarii, Trichostrongylus probolurus, Trichostrongylus colubriformis, Cooperia oncophora, and Nematodirus oiratianus, were identified from dromedary in Iran for the first time. The pathological lesions in the affected abomasums, as well as small and large intestines, were hyperaemic and thickened mucosa with haemorrhagic foci. Histopathological <br />examination revealed inflammatory reaction in the abomasa, flattened mucosa and villous atrophy with <br />inflammatory reactions composed of eosinophils and lymphocytes in the intestines, respectively. The <br />prevalence observed in the present studyindicates the necessity of using an anthelmintic drug for increasing <br />the health and productivity of camels.

Hemorrhagic bowel syndrome is a highly fatal intestinal disease of adult dairy cattle with uncertain <br />cause. In a dairy herd in KhorasanRazavi province, Northeast of Iran, two cows showed depression, <br />anorexia, decrease in milk production, ruminal hypomotility, bruxism and dehydration. At necropsy, massive <br />hemorrhage and clot formation was observed within the jejunum and bacterial culture of the intestinal ingesta <br />and lesions showed the presence of a large number of Clostridium perfringens. Subacute ruminal acidosis <br />was detected in fresh and mid-lactation cows. This report shows the possibility of diagnosis of other <br />hemorrhagic bowel syndrome cases in dairy cows in Iran.

Third-degree perineal lacerations in 7 mares were repaired surgically by a one-stage method (Goetz <br />technique). Primary healing occurred in all of them without any complication. The conception rate obtained <br />after surgery was 70.1%. Five horses out of seven got pregnant after surgery and no further injury was seen at <br />subsequent foaling. Three mares have produced several healthy foals without any subsequent injury. <br />According to the results of the present study, single-stage surgical repairof third-degree perineal laceration <br />(Goetz technique) appeared tohave a good prognosis for subsequent fertility in mares.
