Investigation of Clinical Medicine for Treating Cows Endometritis in Baotou Area

In 4 dairy farms located in Baotou area, clinical medicine investigation and drug resistance of pathogenic bacteria were conducted, and then curative effects of different treatment methods were analyzed.Epidemic materials were collected from diary cows infected by endometritis, from which pathogenic bacteria were isolated using conventional microbiology technologies.Broth microdilution method was used to detect the sensitivity and resistance of pathogenic bacteria to antibiotics commonly used in clinic.On this basis, the sensitive drugs were used to treat mastitis or endometritis, the clinical curative effect of traditional treatment group was compared with that of therapeutic test group.The result of traditional treatment group showed 13 antibiotics were used to treat 160 cases of endometritis, florfenicol was most effective, penicillin was most ineffective.The results of therapeutic test group showed that Staphylococcus aureus, Escherichia coli and Streptococcus were the main pathogenic bacteria of endometritis, which were sensitive to gentamicin and cefalotin, etc.The results of statistical analysis showed that the curative effect of therapeutic test group was extremely significantly different from that of traditional treatment group(P<0.01).Sensitive drugs screened by drug sensitive test could be used to target therapy, and obtain satisfied curative effect.Moreover, this approach could avoid antibiotic abuse.     

An investigation of the shape of the hoof capsule in hindlimbs,its relationship with the orientation of the distal phalanx and comparison with forelimb hoof capsule conformation

There is limited information documenting hind foot conformation. The objectives of the study were to describe the shape of the hoof capsule of hindlimbs from the lateral aspect in horses of variable breeds, and, within horses, to compare the conformation of the hoof capsule of forelimbs and hindlimbs and determine the orientation of the distal phalanx within the hoof capsule in hindlimbs. Lateral photographs of the fore and hind feet (n = 225) and lateromedial radiographs of the hind feet (n = 29) were obtained. Differences among breed and shoeing status groups were assessed using multivariable mixed-effects linear regression models. Angular parameters and ratios of linear measurements were compared between fore and hind feet; angular radiological variables and photographic parameters of the hind feet were compared. The mean dorsal hoof wall angle for hind feet (50.9°±3.7°) was smaller than forefeet (51.8°±3.9°) (P = 0.04). The mean heel angles for hind feet (36.4°±9.6°) were smaller than forefeet (40.1°±9.3°; P < 0.001). Dorsal hoof wall (P < 0.001) and heel (P = 0.002) angles were larger in unshod than shod feet. In the hind feet, the dorsal hoof wall was parallel to the dorsal aspect of the distal phalanx. The median angle of the distal phalanx to the horizontal (angle S) was 0.6° (interquartile range: −1.4, 2.3°). There was a positive relationship between angle S and the hoof wall angle (W); each 1° increase in angle S was associated with 0.6° increase in angle W (P < 0.001). Angle S was also positively associated with photographic heel angle; each degree increase in the angle S was associated with 1.8° increase in the heel angle (P < 0.001). It was concluded that the angle of the distal phalanx to the horizontal in hindlimbs is smaller than published values for forelimbs. The orientation of the distal phalanx in hindlimbs is correlated with external characteristics of the hoof capsule.     

Study on Clinical Efficacy of Oligosaccharide Sulfate and Dextran Sulfate Against Bovine Mastitis

In order to detect the clinical efficacy of oligosaccharide sulfate(DEAE) and dextran sulfate (DS-4000) against bovine mastitis,56 cows with bovine mastitis were divided into 5 groups (DEAE group,DS-4000 group,DEAE＋penicillin group,DS-4000＋penicillin group and penicillin group),and their breasts were perfusion with different drugs twice one day for 3 days.The effective rates of drugs were observed by clinic symptoms.Milk samples were collected before and after treatment of drugs,and the bacterial negative conversion rate of each group were detected by microbial examination.The results showed that total effective rates of 5 groups were 10.00%,20.00%,58.33%,75.00% and 50.00%,respectively,and the bacterial negative conversion rates were 0,12.50%,50.00%,54.55% and 44.44%,respectively.In conclusion,the curative efficiencies of the polysaccharides against bovine mastitis were weak,but it could be improved by combination with penicillin.     

四种替代药剂对梨火疫病菌的抑制活性及其田间防效

为筛选农用链霉素替代药剂,以其为对照药剂,测定春雷霉素、中生菌素、噻霉酮和噻菌铜这4种常用细菌病害防治药剂对梨火疫病菌Erwinia amylovora的抑制活性、对梨火疫病的田间防效及不同药剂处理后梨中的农药残留,并对这4种药剂的作物安全性进行评价。结果表明,中生菌素、噻霉酮和春雷霉素对梨火疫病菌有抑制作用,抑制中浓度EC50分别为1.60、6.64和60.57 mg/L,中生菌素的抑制效果高于链霉素。在连续2年田间试验中,中生菌素1 000倍液和春雷霉素400倍液对梨火疫病的保护效果和治疗效果均达90.33%以上,噻霉酮500倍液和噻菌铜200倍液对梨火疫病的保护效果均达100.00%,治疗效果均超过86.97%,与对照药剂农用链霉素2 000倍液的效果相当。所有药剂处理后均未检出中生菌素、春雷霉素、高效氯氰菊酯和农用链霉素的农药残留,而噻虫嗪、阿维菌素和矮壮素虽有检出,但其残留量均低于国家限量标准。花期前后、幼果期和果实膨大期施药,中生菌素、春雷霉素、噻霉酮和噻菌铜对梨花、叶片、枝梢及果实生长均无不良影响。综合来看,中生菌素、春雷霉素、噻霉酮和噻菌铜均可作为农用链霉素的替代药剂,...

Therapeutic Potential and Nutraceutical Profiling of North Bornean Seaweeds: A Review

Malaysia has a long coastline surrounded by various islands, including North Borneo, that provide a suitable environment for the growth of diverse species of seaweeds. Some of the important North Bornean seaweed species are Kappaphycus alvarezii, Eucheuma denticulatum, Halymenia durvillaei (Rhodophyta), Caulerpa lentillifera, Caulerpa racemosa (Chlorophyta), Dictyota dichotoma and Sargassum polycystum (Ochrophyta). This review aims to highlight the therapeutic potential of North Bornean seaweeds and their nutraceutical profiling. North Bornean seaweeds have demonstrated anti-inflammatory, antioxidant, antimicrobial, anticancer, cardiovascular protective, neuroprotective, renal protective and hepatic protective potentials. The protective roles of the seaweeds might be due to the presence of a wide variety of nutraceuticals, including phthalic anhydride, 3,4-ethylenedioxythiophene, 2-pentylthiophene, furoic acid (K. alvarezii), eicosapentaenoic acid, palmitoleic acid, fucoxanthin, β-carotene (E. denticulatum), eucalyptol, oleic acid, dodecanal, pentadecane (H. durvillaei), canthaxanthin, oleic acid, pentadecanoic acid, eicosane (C. lentillifera), pseudoephedrine, palmitic acid, monocaprin (C. racemosa), dictyohydroperoxide, squalene, fucosterol, saringosterol (D. dichotoma), and lutein, neophytadiene, cholest-4-en-3-one and cis-vaccenic acid (S. polycystum). Extensive studies on the seaweed isolates are highly recommended to understand their bioactivity and mechanisms of action, while highlighting their commercialization potential.

Practical usefulness of a therapeutic soft contact lens for a corneal ulcer in a racehorse

Therapeutic soft contact lenses (TSCL) were applied to a thoroughbred racehorse with corneal ulcer refractory to topical medication. The insertion of the TSCL was conducted on day 36 using a nose twitch under sedation, auriculopalpebral nerve block, and topical anesthesia. The lens was retained, with the duration of wear lasting 114 days. Ocular pain improved immediately and fluorescein tests were negative 17 days after insertion. The horse was able to undergo training and ran in two races while wearing the TSCL. Thus a TSCL was found to be clinically useful for treating corneal ulcers in racehorses.
