The study aimed to evaluate the effects of the kids’ number and sex on the thyroid and lipidic patterns of 30 dairy goats in the advanced mid-gestation and from 30 to 105 days of lactation.

Blood samples were monthly collected to measure circulating thyroid stimulating hormone (TSH), total and free triiodothyronines (T₃, fT₃) and thyroxines (T₄, fT₄); triglyceride (TG), total cholesterol (tCho), and very-low-density lipoprotein cholesterol (VLDL Cho).

Dams carrying a single foetus showed higher T₄ concentrations (P < 0.04) at >130–150 days than those carrying twins. Dams carrying one/two males had the highest fT₃ (P < 0.001) and fT₄ (P < 0.03) concentrations at 95–115 days and the highest fT₃ (P < 0.0001) and TSH (P < 0.002) at >115–130 days. Dams kidding male and female twins showed the highest TG and VLDL Cho concentrations (P < 0.04) at >70–105 days of lactation.

Single or twin births influenced the thyroid activity of pregnant goats, with a specific effect of foetal number on T₄ and of foetal sex on fT₃ and fT₄ concentrations. Kids’ number and sex affected TG and VLDL Cho in lactating dams. This suggests that foetal number and sex are not a random chance event but an interactive process between maternal and foetal endocrine and metabolic processes.

本研究旨在评估30只妊娠中期和哺乳期30-105天的奶山羊的数量和性别对甲状腺和血脂模式的影响。每月采集血样以测量循环促甲状腺激素（TSH）、总的和游离的三碘甲状腺原氨酸（T3，fT3）和甲状腺素（T4，fT4）；甘油三酯（TG）、总胆固醇（tCho）和极低密度脂蛋白胆固醇（VLDL-Cho）；130–150天。携带1/2只雄性的水坝在95–115天时具有最高的fT3（P＜0.001）和fT4（P＜0.03）浓度，在>；115–130天。开玩笑的雄性和雌性双胞胎在>；哺乳期70–105天。单胎或双胎出生会影响怀孕山羊的甲状腺活性，胎儿数量对T4有特定影响，胎儿性别对fT3和fT4浓度有特定影响。哺乳期母鼠的儿童数量和性别影响TG和VLDL Cho。这表明，胎儿数量和性别不是一个随机的偶然事件，而是母体和胎儿内分泌和代谢过程之间的互动过程。

Objectives

This study was performed to evaluate the effectiveness of ultrasound-guided injections in lesions of suspensory ligament branches of an autologous standardized leukocyte poor platelet-rich plasma.

Methods

Nine sport horses with front legs suspensory ligament branch desmopathies (SLBD) were included in the study. A clinical examination and ultrasound evaluation of the affected suspensory ligament branches were carried out at the time of inclusion and on a monthly basis for 6 months after the first platelet-rich plasma (PRP) injection. Twelve branches were treated with 2–3 injections spaced by 2 weeks. Long-term follow-up at 12 months and up to 24 months for 6 horses were carried out by means of telephonic interviews with the owner.

Results

Ten out of 12 branches presented resolution of the hypoechoic lesions within three months and the treatment was associated with rapid resolution of lameness. Six of the 9 horses returned to their previous workload, 2 were in a lower level and 1 was retired.

Conclusions

Two to three intralesional injections with RegenPRP in SLBD contributes to a rapid resolution of lameness and ultrasonographic lesions without complications. This treatment should be considered to increase the number of horses reaching their previous level of performance. Clinical results confirm that the use of a standardized autologous leukocyte poor PRP represents a convenient alternative treatment for SLB lesions.

目的本研究旨在评价超声引导下注射治疗自体标准化贫白细胞富血小板血浆悬韧带分支病变的有效性。方法对9匹患有前腿悬吊韧带分支桥连病（SLBD）的运动马进行研究。在纳入时每月对受影响的悬吊韧带分支进行6次临床检查和超声评估 在第一次富血小板血浆（PRP）注射后数月。12个分支接受2-3次注射，间隔2次 周。12岁时的长期随访 月至24 对6匹马进行了为期数月的电话采访。结果12个分支中有10个分支在3个月内表现出低回声病变的消退，治疗与跛行的快速消退有关。9匹马中有6匹马恢复了以前的工作量，2匹马处于较低级别，1匹马退役。结论在SLBD中，两到三次病灶内注射RegenPRP有助于快速解决跛行和超声病变，而不会出现并发症。这种治疗应该考虑增加达到先前水平的马匹数量。临床结果证实，使用标准化的自体低白细胞PRP是SLB病变的一种方便的替代治疗方法。
