The study was conducted on genitalia collected from 100 dairy cows/heifers from the Meat Technology Unit, Mannuthy. The animals brought for slaughter at Meat Technology Unit, Mannuthy were from herds of five different farms (University and Government Undertaking farms) in Kerala state. This included six animals culled on account of factors other than infertility with normal reproductive system (control group) and the remaining animals with a known history of infertility. In total, seven animals showed kinked cervix condition. Cervix was evaluated morphometrically and histologically. Grossly, the cervix was hard, kinked and S-shaped, with a mean length of 9.64 ± 1.19 cm. Average number of annular rings in the cervical canal was 4.14 ± 0.26 with an average diameter of 1.74 ± 0.18 cm. At the external os, diameter of the cervix was less, while at the uterine end, diameter was more. The opening of each cervical ring showed a misalignment instead of a straight line. Histologically, the cervix was lined by simple columnar epithelium with signs of degeneration and desquamation. However, the submucosal layer was extensively infiltrated by collagen fibres. In uterus, there was a significant difference in the number of endometrial glands and height of the glandular epithelial cells which was less when compared to the control group. Muscular layer outer to connective tissue layer was thin and uneven. Alterations of the glandular structures negatively influence the viability of spermatozoa due to the lack of secretory products. This fibrous, collagen rich kinked cervix limits the smooth deposition of the semen into the uterus during artificial insemination and the insufficiently dilated cervix affects its contractibility leading to dystocia and subfertility.

Secretory Products

Excretory/Secretory Products (ESPs) of the nematode Trichinella spiralis contain antitumor-active substances that inhibit tumor growth. Mature dendritic cells (DCs) play a critical role in the antitumor immunity of the organism. As pathogen-derived products, it ought to be discussed whether T. spiralis ESPs will reduce the antitumor effect of mature DCs from the host before it is applied to patients’ tumors. Therefore, the aim of this work was to evaluate the immunological effect of DCs stimulated by T. spiralis ESPs in H22 tumor-bearing mice. H22 tumor model mice in this study were randomly divided into four groups according to the treatment: PBS control group, ESP group, DCs group, and DCs stimulated with T. spiralis ESP (ESP+DCs group). The antitumor effect was evaluated by tumor inhibition rate and cytokine detection using ELISA. The results showed significant inhibition in tumor growth in the ESP+DCs, DCs and ESP groups when compared with the PBS control group (p < 0.01, p < 0.01, and p < 0.05, respectively). However, no significant difference was observed on tumor inhibition rates between the ESP+DCs and DCs groups. The decrease in IL-4, IL-6, and IL-10, and the increase in IFN-γ between the DCs and ESP+DCs groups were also not significant. Therefore, DCs stimulated by ESP did not reduce the antitumor effect of mature DCs, which demonstrated that the T. spiralis ESP would not affect the antitumor effect of mature DCs by modulating the immune response of the host, and that ESPs are safe in antitumor immunology when applied in a tumor model mice.

Objective: To investigate the effect of cervical cone excision on cervical canal length in patients with high cervical intraepithelial neoplasia. Methods: 30 cases of patients with high-grade cervical intraepithelial neoplasia who admitted in our hospital and underwent cervical cone resection were selected as the experimental group and 30 cases of healthy pregnancy at the same period were selected as the control group. The experimental group was given cervical conization. The cervical canal length of patients in the experimental group, the cervical canal length of successful pregnancy patients, pregnancy and pregnancy outcome pregnancy of the two groups were detected after treatment. Results: Compared with the control group ,the cervical tube length level was significantly lower in the experimental group after treatment (P<0.05);the cervical tube length of successful pregnancy underwent cervical conization at 12 weeks , 20 weeks, 28 weeks after pregnancy showed no significant difference (P>0.05), the successful pregnancy rate of experimental group after surgery was lower(P<0.05), the incidence of pregnancy with preterm premature rupture of membranes, umbilical cord around the neck prematurity and cases of term delivery number between experimental and control groups showed no significant difference between two groups(P>0.05). Conclusion: The cervical canal length level of patients with high-grade cervical intraepithelial neoplasia was lower after cervical conization, the successful pregnancy rate was low, the pregnancy cervical tube length and the rate of preterm birth had no difference compared with normal pregnant women.

AbstractOverall reproductive performance and associated periparturient disorders were monitored in a herd of British Friesian cross dairy cows from September 1987 to August 1988. Pregnancy diagnosis and cyclical status of the herd was determined by palpation of the ovaries per rectum. A total of 49 (110) cows were randomly treated with Sepia 200c either on day 14(19) or 21 days (30) postpartum.Statistical analysis of the results was based on the differences between the control and combined Sepia-treated groups. Although there were significant differences in the proportion of heifers calving in each group, there was no significant difference in periparturient disorders or during the pre-service period.However, in the Sepia Group that held a lower proportion of heifers, a significant difference was found in the conception rate to 1st service (47%), the percentage of cows in calf (90%) and total culling rate (10%) compared to the Control Group (26%, 72% and 28% respectively). A reduction (non significant) was found between the Sepia and Control services to conception (0.2), calving to conception interval (5 days) and calving index (2 days).The results of this pilot study appear to demonstrate a difference in effect between the Sepia-treated Group and Control Group. The study has been extended to treat a larger number of dairy cows to examine the reproducibility of these results.

Abstract Infectious diseases can occur in all parts of the body. One of the causes infection in humans is Eschericiae coli bacteria. Eschericiae coli is a rod-shaped bacteria, a gram negative bacteria, facultative aerobics and classified family member of Enterobacteriaceae from the Gammaproteobacteria class. Along the times, E.coli bacteria have resistent to some antibiotics. So we need a new alternative. There is a antibacterial substance in the isoflavon group contained in edamame. Genistein is a main isoflavon in edamame that have antiinflammation, antibacterial, and antioxidant effects. The purpose of this study was to determine is there any antibacterial effects in ethanol edamame seeds extract to E.coli bacteria. This study used a true experimental research design in vitro with a post test only control group design.  The average diameter results of the inhibition zone were analyzed using the Kruskal-Wallis method and obtained p = 0.001 which means there are significant differences in at least two groups. After that, the Mann Whitney post hoc test was conducted and a significant difference was found in the positive and negative control groups for all groups but there was no difference in the treatment group, both groups K1, K2 and K3 for all groups.

Milk yield, milk ingredients, health and other, production-related parameters of subclinically infected, Mycobacterium avium ssp. paratuberculosis (MAP-) shedding (positive faecal PCR, n = 20) and non-shedding (negative faecal PCR, n = 10) dairy cows were compared in the period from 10 days prepartum to 120 days postpartum. Body condition, rumen fill and faeces scores were lower in the MAP-shedding cows. There was no significant difference in plasma or urine metabolic parameters between the groups. Milk yield and lactose content tended to be lower (P = 0.074 and 0.077, respectively), somatic cell count tended to be higher (P = 0.097), while milk fat content was significantly higher (P = 0.006) in MAP-shedding cows than in the controls. Milk protein content did not differ between the groups. All other health and production parameters [number of reproductive tract treatments, number of udder treatments, number of artificial inseminations (AIs), calving interval, and service period] were significantly better in the control group. It is concluded that MAP infection, even in a subclinical form, has a significant impact on some production and health parameters of dairy cows.

Objective (s): The aim of the study was to assess ovarian reserve (OR) of patients with endometrioma and to explore the differences of ovarian reserve in age matched group of infertile patients without endometrioma.Materials and methods: This prospective analytic study was done in Infertility Care and Research Center, between January 2013 and December 2015 to assess the ovarian reserve of patients with endometrioma. During this period 105 patients of endometriosis with endometrioma were selected for study. Selection criteria were: no history of previous surgery, <36 years of age, no history of endocrine problems, no history of recent medical treatment for this condition within 6 months and no history of irregular menstruation. For ovarian reserve testing we assessed serum FSH, E2 and AMH. Patient of same age group who had no emdometrioma, no history of any surgery, no menstrual irregularity, endocrine disorder or any other medical diseases were taken as control to compare the ovarian reserve between these two groups. For control group also we did the same tests. Data was analyzed by SPSS package. One-way ANOVA test was done for test of significance. A p-value of <0.05 was considered as significant.Results: There was no difference in characteristics of patients of both groups regarding age, type of infertility and duration of infertility. Size of the endometriotic cysts were variable and average diameter of cyst was 6.2 ±2.32 cm. Most (58.10%) of the cysts were unilateral. There is a significant difference of FSH and AMH level between the groups. FSH of endometrioma and non-endometrioma group was 7.9 ±1.17 and 7.1 ±1.05 mIU/mL respectively with a p value of 0.029. Similar difference was present in AMH level, which was 2.42 ±.63 and 2.98 ±.88 ng/ mL in endometrioma and non-endometrioma group respectively with a p value of 0.020.Conclusion: This small study shows a reduced ovarian reserve in patients with endometrioma in comparison to patients of same parameters without endometrioma. It suggests that there is an association of presence of ovarian endometrioma and reduced ovarian reserveBangladesh J Obstet Gynaecol, 2015; Vol. 30(2) : 98-104

This study aimed to determine the incidence of latent acidotic stress (LAS), which is an important problem in dairy cow breeding in Turkey, to investigate net acid-base excretion in urine, and to provide veterinary doctors with information about the early diagnosis and treatment of LAS. Two study groups were formed according to the rumen fluid pH values: LAS group (19 cows) with 5.2 < pH < 6.0 (19 cows) and healthy group (81 cows) with 6.0 < pH < 7.2. Blood, urine and ruminal fluid samples were taken after a general clinical examination of the animals. The physical properties of the rumen fluid, methylene blue reduction time, total infusoria number, and volatile fatty acid (VFA) amounts were determined. In addition, examinations of blood gases, urine pH, and net acid-base excretion (NABE) were performed. The general physical examination did not reaveal any statistically significant difference in the body temperature between the LAS group (n = 19) and the control group (n = 81) (p = 0.614), but a significant increase in the heartbeat, respiratory frequency, and the number of rumen movements was observed in the LAS group (p = 0.001). The following findings were observed in the rumen fluid from cows of the LAS group: decreased methylene blue reduction time (p = 0.001), decreased pH (p = 0.001) and infusoria density (p = 0.001), increased sedimentation time (p = 0.001) and total VFA amount (p = 0.001), no flotation. Compared with the healthy cows, the LAS group showed decreased blood pH (p = 0.001) and oxygen pressure (pO2) (p = 0.001), increased carbon dioxide pressure (pCO2), base excess (BE) and bicarbonate (HCO3) values (p = 0.001), and decreased urine pH (p = 0.001) and net acid-base excretion (p = 0.001) values. The incidence of latent acidotic stress in dairy cows in the Sanliurfa region was determined as 19%. In addition, it was concluded that net acid-base excretion values in urine can be used as an auxiliary parameter in the diagnosis of LAS and can be easily applied in the field.

Abstract Aim A unique characteristic of some new bonding systems in operative dentistry is they combine conditioning and priming agents into a single acidic primer solution for simultaneous use on both enamel and dentin. Combining conditioning and priming into a single treatment step results in improvement in both time and costeffectiveness to the clinician and, indirectly, to the patient. The purpose of this study was to determine the effects of the use of a self-etching primer on the bond strength of orthodontic brackets and on the bracket/ adhesive failure mode. Methods and Materials Thirty-six fresh bovine incisors were collected and stored in a solution of 0.1% (weight/volume) thymol. The criteria for tooth selection included intact buccal enamel, no cracks caused by the presence of the extraction forceps, and no defects. The teeth were cleansed and polished with pumice and rubber prophylactic cups for ten seconds. Brackets were bonded to the teeth according to one of three protocols following the manufacturers’ instructions - Group 1: Conventional multistep bonding system (control group) (n=12); Group 2: Self-etching primer system (n=12); and Group 3: Acid+self-etching primer system (n=12). Specimens were loaded to failure in a Zwick test machine (Zwick GmbH & Co, Ulm, Germany). Shear bond strengths were measured at a crosshead speed of 5 mm/min. Results The mean shear bond strength in megapascals (Mpa) (standard deviation) were 11.7 (4.2), 10.5 (4.4), and 10.9 (4.8) for Groups 1, 2, and 3, respectively. The analysis of variance (ANOVA) was used to compare the three groups. The results indicated no significant difference in the bond strength between the three groups (P=0.800). The results of the Chi square test, evaluating the residual adhesives on the enamel surfaces, revealed no significant difference between the three groups (P=0.554). Conclusion Results of the present in vitro study indicate the use of self-etching primers may be an alternative to conventional phosphoric acid pre-treatment in orthodontic bonding.

Rumen Acidosis

Monensin has been shown to decrease mortality and morbidity in feedlot cattle by reducing the incidence of acute and subacute rumen acidosis (SARA). Lately, the technique of real-time observance of reticuloruminal temperature and pH, which involves placement of indwelling pH probes in the reticulum or in the rumen has gained in popularity. In this study, we aimed to determine, using real-time monitoring in fresh dairy cows, how monensin controlled release capsules affect the reticulorumen temperature and pH. We used a slow-release rumen preparation, which emitted daily monensin doses of 335 mg. Following the manufacturer’s instructions, the preparation was administered through an oral balling gun. The following points indicate the method for determining the two experimental groups: (1) monensin-supplemented test group (TG) (a 32.4 g monensin controlled release capsule, MCRC, n = 20) and (2) a control group (CG) (capsule containing no monensin, n = 20). Both began a day after calving, and one month after calving the experiment was finished. A set of smaXtec boluses fabricated for animal care was used to measure the temperature and pH of the reticulorumen. After the first day of the study, a statistically significant difference between reticulorumen temperature in CG (38.67 ± 0.10 °C) and TG (39.08 ± 0.09 °C; P &lt; 0.01) was found. The use of the monensin controlled release capsule, which emitted daily monensin doses of 335 mg, in the first 30 days after calving increased the reticulorumen pH by 1.89% (P &lt; 0.001), and the temperature of the reticulorumen by 0.82 % (P &lt; 0.001). We conclude that using monensin in the form of monensin controlled release capsules reduces the risk of SARA. Real time observation of temperature and pH levels in the reticulorumen in fresh dairy cows allows for evaluation of the risk of SARA and provides the opportunity to determine the prophylactic effect of those capsules.
