【摘要】 目的 觀察胎羊宮內心臟介入手術胎羊血氣及血漿炎性細胞因子的變化。方法 8只懷孕雙胎山羊,雙胎之一為實驗組,在相同麻醉條件下,實驗組進行胎羊心臟介入治療,并抽取血樣標本。監測胎羊的心率、血氣、乳酸值,運用ELISA法檢測治療組及對照組胎羊白介素(IL)1、IL6、IL8及腫瘤壞死因子(TNFα)。結果 2只胎羊因手術中發生心包填塞死亡,存活的6只胎羊手術前pH值較手術后有明顯下降(Plt;005),手術前后乳酸濃度上升(Plt;005),PCO2、PO2差異無統計學意義(Pgt;005),手術前血漿IL1、IL6、IL8的濃度較手術后高(Plt;005),手術前后TNFα的濃度變化無統計學意義(Pgt;005)。結論 胎羊宮內心臟介入手術可引起胎羊血漿pH值下降,乳酸濃度上升,及細胞因子IL1、IL6、IL8濃度上升。【Abstract】 Objective To observe the change of blood gas and inflammatory cytokines during intrauterine cardiac intervention surgery on the fetal lambs. Methods Eight pregnant goats with two fetal in each goat were included. With the same anesthesia condition, one of the twin fetus was chose to perform the intrauterine cardiac intervention surgery. The fetal heart beating rate was monitored, and blood samples of the fetus were taken to do the blood gas analysis and to detect the concentration of inflammatory cytokines (IL1, IL6, IL8, and TNFα). Results Two of the eight fetal lambs which was died in the operation because of pericardial tapenade. In the other six survived fetus, the PH was lower than after the surgery, and the concentrations of lactic acid, IL1, IL6, and IL8 are higher than after the surgery. There was no significant difference of PCO2,PO2 and TNFα between before and after the surgery. Conclusion The intrauterine cardiac intervention surgery can make the PH of fetal plasma lower and the concentrations of lactic acid and IL1, IL6, IL8 higher.
Objective?To study the mid-facial development characteristics of the goats with cleft palate after in-utero surgical repair at different stages.?Methods?Twenty-four Boer hybrid female goats were selected, aged from 8 to 12 months and weighing from 35 to 55 kg. The mating day was designated for 0 day. At 30 days, pregnant was confirmed by B-ultrasound test, and the goats were divided into 5 groups (experimental groups 1, 2, 3, 4, and normal control group). Twenty pregnant goats of 4 experimental groups (n=5) were injected DL-anabasine (15 mg/day) from 31 to 42 days to establish cleft palate model of fetal lamb, 4 pregnant goats of normal control group used as controls without injection. At pregnant 65, 90, and 120 days, cleft palate was repaired in the uterus in experimental groups 1, 2, and 3, while cleft palate was not repaired in experimental group 4. After 1 month of birth, the maxillary bone width (posterior premolar morphological measurement, PPMM) and the maxillary bone length (anterior premolar morphological measurement, APMM) were measured with CT scanning. The dry skull of goats were harvested for gross observation.?Results?There was no significant difference in PPMM and APMM between experimental group 1 and the normal control group (P gt; 0.05), but there were significant differences between experimental groups 1 and 4 (P lt; 0.05) at 1 month after birth. Significant differences were oberved in PPMM and APMM between experimental group 2 and normal control group, experimental group 4 (P lt; 0.05). There were significant differences in PPMM between experimental group 3 and normal control group, experimental group 4 (P lt; 0.05), in APMM between experimental group 3 and normal control group (P lt; 0.05). Five goats with cleft palate in experimental group 4 died at 1-2 months after birth.?Conclusion?At pregnant 65 days, in-utero surgical repair of cleft palate has less influences on mid-facial development. The earlier repair is performed, the higher risk of miscarriage was.
