双峰驼脾脏的组织形态学观察 总被引:5,自引:0,他引:5
骆驼脾脏的形状和其它动物明显不同,为镰形,外缘呈锯齿状。其被膜很厚,富含平滑肌和弹性纤维,平滑肌层比结缔组织层厚,主要由相互垂直的两层构成。次级平滑肌性小梁发达,相互交织成网状,构成红髓的主要支架。白髓有典型的脾小结和动脉周围淋巴鞘,无边缘窦。边缘区明显,分布在脾小结、动脉周围淋巴鞘周围,可见大量吞噬含铁血黄素、ACP活性很强的巨噬细胞,开口于此的中央动脉分支十分丰富。鞘毛细血管主要分布在边缘区,其次是脾索的滤过区,白髓发达的个体更为多见,常见红细胞从椭球漏出,但胞质中未见含铁血黄素,ACP呈色反应呈阴性。脾索滤过区可见大量的毛细血管和吞噬有含铁血黄素、ACP活性很强的巨噬细胞。脾窦十分发达,窦壁细胞ACP和AKP均呈强阳性,窦腔中也有上述巨噬细胞。淋巴细胞在脾脏中的分布和其它动物及人相似。上述结果证实,骆驼脾脏属于免疫功能很强的防御性脾。 相似文献

试验应用血管铸型方法,对14枚(左肾7枚,右肾7枚)绵羊肾动脉分支分布做了研究。肾动脉在进入肾门前有两种分支形式:前后干型和背腹干型,后者占主要。背腹干分布形式的肾脏,背干在进入肾窦内分为一前支和一后支,由前支和后支发出肾脏背部各肾段动脉。腹干不分支而直接发出肾脏腹部各肾段动脉。各肾段动脉之间未见有吻合支。绵羊肾脏不论肾动脉是前后干型还是背腹干型,肾段动脉的数目均为7。肾段动脉分布的区域即为肾段,所以与之相应的肾段也有7个。 相似文献

Bactrian camel is an ancient and precious species of livestock; that is, unique resources exist in the desert and have important economic and scientific value. In recent years, the number of Bactrian camels has declined sharply. Due to its long reproductive cycle and seasonal oestrus, the mechanism of oestrus is unknown. To identify candidate biomarkers of reproduction, we performed a comprehensive proteomic analysis of serum from Bactrian camel in oestrus and non-oestrus, using isobaric tags for relative and absolute quantitation (iTRAQ) coupled with tandem mass spectrometry. We identified 359 proteins, of which 32 were differentially expressed: 11 were up-regulated and 21 were down-regulated in samples from camels in oestrus. We validated the differential expression of a subset of these proteins using qPCR and Western blot. Gene ontology annotation identified that the differentially expressed proteins function in cellular processes, metabolic processes and immune system processes. Notably, five of the differentially expressed proteins, PCGF5, histone H1.2, RBP4, FOLR1 and ANTXR2, are involved in reproductive regulatory processes in other animals. KEGG enrichment analysis demonstrated significant enrichment in several cardiac-related pathways, such as ‘dilated cardiomyopathy’, ‘hypertrophic cardiomyopathy’, ‘cardiac muscle contraction’ and ‘adrenergic signalling in cardiomyopathy’. Our results suggest that candidate biomarker (PCGF5, histone H1.2, RBP4, FOLR1 and ANTXR2) discovery can aid in understanding reproduction in Bactrian camels. We conclude that the profiling of serum proteomes, followed by the measurement of selected proteins using more targeted methods, offers a promising approach for studying mechanisms of oestrus. 相似文献

To establish the reversed phase high-performance liquid chromatography (RP-HPLC) method for determination of plasma concentration of acetaminophen in Bactrian camel, the chromatography was carried on a C18 column (150 mm×4.6 mm,5 μm).The mobile phase was composed of methanol-water (20:80),the flow rate was 0.5 mL/min,and the detection wavelength was set at 248 nm for acetaminophen.The retention time of acetaminophen was 6.5 min, and was not disturbed by other miscellaneous peaks.The calibration curve was linearity in the range of 0.08 to 10.24 μg/mL (R2=0.9997),and the quantitation limit of acetaminophen was 0.10 μg/mL.Both the inter-day and intra-day RSD were under 7.0%, the absolute recovery of the method was 80.39% to 93.56%,the relative recovery of the method was 94.66% to 104.73%.Therefore, the established method was simple, reproducible and accurate,which could be used for determination of plasma acetaminophen concentration and in vivo activities of CYP1A enzyme in Bactrian camel. 相似文献

试验旨在建立测定双峰驼血浆中对乙酰氨基酚浓度的反相高效液相色谱法(reversed phase high-performance liquid chromatography,RP-HPLC)。选用Supelco Discovery C18色谱柱(150 mm×4.6 mm,5 μm),以甲醇:水=20:80为流动相,流速为0.5 mL/min,紫外检测波长为248 nm,采用甲醇直接沉淀蛋白方法处理血浆样品。结果表明,对乙酰氨基酚的保留时间为6.5 min,分离度良好,无血浆杂峰干扰,且在0.08~10.24 μg/mL浓度范围内线性关系良好(R2=0.9997,n=8),检测限为0.10 μg/mL,日内和日间精密度RSD均小于7.0%,绝对回收率为80.39%~93.56%,相对回收率为94.66%~104.73%。因此,本试验所建立的RP-HPLC法操作简便、准确,重复性好,专属性强,适用于检测双峰驼血浆中对乙酰氨基酚浓度,为后续的借助特异性探针药物--对乙酰氨基酚研究双峰驼CYP1A酶的体内活性提供了可靠而准确的定量方法。 相似文献

The arterial supply of the six carpal joints was studied in Bactrian camels. The arterial branches supplying the carpal joints were the proximal medial dorsal, middle medial dorsal, distal medial dorsal, proximal lateral dorsal, distal lateral dorsal, proximal medial palmar, distal medial palmar, lateral palmar, proximal palmar and dorsal palmar carpi and the dorsal interosseous antebrachium branches. Some small unnamed branches supplied the diverticulum and the antebrachiocarpal joint capsule. All these arteries arose from the lateral and medial branches of the radial artery. 相似文献

Seven heads and necks of Bactrian camels were dissected to investigate the origin, course, branches anddistribution of the accessory nerve and vagus nerve in the cranial cervical region. The spinal root and external branch of the accessory nerve were not present, but there was a delicate communicating branch between the dorsal root of the first cervical nerve and the root of the vagus nerve. The sternocephalic muscle was innervated by the second cervical nerve while the brachiocephalic and trapezius muscles were supplied by the sixth and seventh cervical nerves. In the head and cranial cervical region of the Bactrian camel the vagus nerve gave oft the auricular branch, pharyngeal branch, cranial laryngeal nerve, a common trunk to the larynx, oesophagus and trachea, and some communicating branches connecting with the glossopharyngeal, hypoglossal, first cervical nerves and the cranial cervical ganglion. 相似文献
