Our trial was conducted to study the effects of formic acid(FA) and potassium di-formate(KDF) in broiler ration on performance, carcass traits, blood biochemical, intestinal microbial load, histological picture of intestine and immune parameters of broilers. In this study 360 one-day-old broiler chicks were divided to 3 groups with 3 replicates of 40 chicks each. The trial continued for 35 days. The control group was fed only basal diet(G1). Group 2(G2) were fed basal diet supplemented with FA(5 g/kg diet), and group 3(G3) received basal diet supplemented with KDF(5 g/kg diet). The results showed that both FA and KDF significantly increased body weight gain(BWG), dressing percentage of broilers and significantly decreased feed conversion ratio(FCR)(P < 0.05). The highest percent of breast and thigh was observed in G3. The improvement in villus height was observed in G2 and G3 compared with the control one, and the highest was in G3. The results evidence that the using of FA or KDF in broiler feeds have significant effects on performance, immune parameters, and gut health without having any significant effects on blood biochemical. However, KDF is more effective than FA as little amount of FA reaches the small intestine due to metabolism and absorption, whereas KDF permits a proportion of FA to pass through the fore-gut intact and enter the small intestinal tract. In addition, FA has a strong odor and corrosiveness to gastrointestinal tract which limits its use.

In No. 3 coalseam of Chengzhuang Coalmine of Jincheng City, there exists the visible fracture system consisting of joints, gas-expanding fractures and cleats. The gas-expanding fractures develop mainly in the bright coal sub-layer and cleats, in the vitrain and bright coal. The joints fall into two types, one developing in the coalseam and the other cutting through the whole coalseam and entering into the top and bottom rock layer. The development direction of joints is basically similar to that of gas-expanding fractures: NNE and NNW. The formation of the visible fracture system is classified as the stage of the development of cleat fissures in the coalification period, the stage of the full development of cleats and the formation of gas-expanding fractures in the second coalification period and the stage of the formation of joints by structural function. There is the spatial unhomoge-neity in three dimensions for the visible fracture system of the coal seam in Chengzhuang Coalmine: the regular distribution of the visible fractures as groups in the plane and the coal sub-layer with high permeability rate in profile. The research findings of the visible fracture system of coal seam can be applied to the drilling of the coalbed methane and to heightening the let-off efficiency of coalseam gas.

Objective: The purpose of this study was to evaluate the impact of labor pain intensity and labor pain catastrophizing on maternity blues and postpartum social functioning. Study design: Pain intensity and pain catastrophizing were assessed in 89 women in active labor before the administration of analgesia. Both these measures were assessed again retrospectively 2 days after delivery in 82 women who had a spontaneous vaginal delivery. Women also filled out the Edinburgh Postnatal Depression Scale. Six weeks later women completed the social functioning domain of the short form SF36 health survey. Results: Pain catastrophizing during labor significantly predicted both maternity blues (P =. 001) and postpartum social functioning (P =. 001) when being controlled for maternal age and education, parity, type of analgesia, and labor pain intensity. Low level of education and younger age also contributed to the prediction of maternity blues and social functioning. Conclusion: Labor pain catastrophizing rather than labor pain intensity predicts postpartum maternal adjustments.

Objectives: To study the incidence of toxoplasmosis in pregnant women in Crete and to test a designed protocol for handling those at risk of delivering congenitally infected infants. Study design: Pregnant women were screened serologically over a period of 5 years. Cases with suspected acute toxoplasmosis were treated, peripheral blood (PB), and amniotic fluid (AF)tested by polymerase chain reaction (PCR) and culture, and fetuses monitored by ultrasonography. The absence of congenital infection in infants was confirmed by serology and clinical evaluation. Results: Of the 5532 pregnant women followed, 70.57%remained seronegative, 29.45%were seropositive, and there was direct evidence of seroconversion in six cases. Acute toxoplasmosis was suspected in 185 cases, maternal parasitemia was detected in five cases and positive amniotic fluid in one case. Congenital infection was excluded in all infants followed, based on the absence of ultrasound findings in utero, lack of clinical symptoms at birth, negative Western blotting (WB) at birth and 3 months later, and descending serology for a year. Conclusion: Overall, 29.45%of the pregnant women followed were seropositive, 3.3%with suspected acute toxoplasmosis, and in 0.02%cases there was evidence of maternofetal transmission. The protocol tested allowed differentiation between acute andlatent toxoplasmosis, safe management of the cases at risk and assisted in avoidance of unwarranted pregnancy terminations.

The aim of this study was to determine the clinical implications of migraine in systemic lupus erythematosus (SLE)using the cumulative organ damage scores (SLICC- DI). Eighty SLE,40 rheumatoid arthritis (RA) patients and 40 controls (non SLE, nor RA out- patients), all women, were included. Migraine was defined according to the International Headache Society (IHS) criteria for neuropsychiatric SLE. Disease activity was measured by MEX- SLEDAI and cumulative organ damage by SLICC- DI. Statistics were obtained by Chi- square and Fischer’ s exact tests. ANOVA was used for comparing means. Migraine was identified in 42.5% of SLE patients, compared to 12.5% of RA patients (P < 0.05) and 10.0% (P < 0.05) in the control group. In the SLE group, a significant association between migraine and Raynaud’ s phenomenon (P = 0.003, OR = 10.1; 95% CI 2.9- 35) and antiphospholipid antibodies (P = 0.0012; OR = 7.5; 95% CI 2.5- 22.9) was noted. SLE patients with active migraine had higher MEX- SLEDAI scores than SLE patients without migraine. SLE patients with past history of migraine had significantly higher SLICC scores than SLE patients without migraine. History of migraine was associated with greater organ damage. Active migraine was associated with higher disease activity, antiphospholipid antibodies and worsening of Raynaud s phenomenon. The increased cumulative organ damage in SLE patients with past history of migraine justifies the routine evaluation of migraine in clinical practice.

The effects of pigment glands and gossypol on the somatic cell culture of upland cotton were studied, using the materials as follows: three pairs of glanded and gland less upland cotton near isogenic lines, TM-1, and Coker 312. The results showed that the pigment glands and gossypol contents in the explants had great inhibiting effect on the induction and growth of callus in somatic cell culture of upland cotton, and the induction rate of callus and the single callus weight of glandless cotton were much higher than those of their glanded near isogenic lines. It was easier to obtain regeneration plants from glandless cotton than from their glandednear isogenic lines. There was a significant inverse correlation between the gossypol contents in the explants and callus induction rate, with the correlation coefficient of -0.84. The vitro gossypol in the medium had some inhibiting effect on the induction and growth of callus, especially for the gland-less cotton. However, a certain concentration of vitro

RHEUMATOID arthritis (RA) is an autoimmune disease which progressively and systematicallyinvades the joints of bones. A severe chronic situation may lead to the damage of cartilages,bones and tendons and eventually handicap the patients. One of the main histopathological fea-tures of rheumatoid synovium is a marked increase of the thickness and the number of cells inthe synovial lining layer. It is well known that the synovial lining cells secrete many cell fac.

The volatilization kinetics of antimony trisulfide in steam atmosphere was studied with thermogravimetry at temperatures from 923 to 1123 K. A theoretical model was developed to calculate the overall rate constant and the mass transfer coefficient in gas phases. The experimental results show that the volatilization rate is enhanced with increasing temperature and steam flow rate. The volatilization rate is mainly controlled by the mass transport in gas phases. The apparent activation energy for the process is found to be 59.93 kJ/mol. It is demonstrated that Sb2S3 is dominantly oxidized into Sb2O3 and H2S by water vapor in the volatilization process. Some antimony metal is formed. The reaction mechanism is discussed in accordance with experimental data.
