The primo vascular system (PVS) in a lymph system was observed mostly in large caliber ducts around the caudal vena cava of rabbits, rats, and mice. This required a severe surgery with laparectomy and massive removal of fat tissues in the abdomen to expose the lymph vessel. In the current brief report, we presented a new method to evade these shortcomings by observing the PVS in a less large caliber duct in the skin, that is, the lymph vessel from the inguinal to the axillary nodes. The Alcian blue injection into the inguinal node revealed the desired primo vessel in the target lymph vessel. This opened a new perspective for the investigation of the lymphatic PVS without severe damage to subject animals and for monitoring of the PVS in a long period of time.

The primo vascular system (PVS) floating in lymph fluid has mostly been observed in large caliber ducts around the caudal vena cava and the thoracic duct of rabbits, rats, and mice. But the PVS has not been traced up to the lymph nodes. It has not been established whether the PVS leaves the lymph vessel through the lymph vessel wall or it enters the lymph nodes. Therefore, observing the PVS entering a lymph node, for example, the axillary node, is desirable. In the current work, we traced the PVS approaching up to the surface of axillary node of a rat. The method used for this study was based upon a method that was recently developed to detect the PVS in the lymph duct from the inguinal to the axillary nodes in the skin of a rat by injecting Alcian blue into the inguinal node. However, the Alcian blue blurred near the lymph nodes and tracing the PVS up to the lymph nodes has not been possible. The current method clearly showed the PVS approaching the axillary node.

Lymph System

Though primo vessels are frequently found in the lymph near the abdominal aorta of rabbit by Alcian blue dye, the reproductions are still difficult to require considerable skills and technical know-how at dissected tissue of animal species. However, in the inguinal lymph node of a rabbit we found a long-type primo vascular system (LTP) dyed with Alcian blue, from an abdominal lymph vessel to an inguinal lymph node. The length of LTP was over an average length of 9.1 cm. The average diameters of the primo and the lymph vessels were about 23.9 μm and 242 μm, respectively. The primo vessels were not floating but adhered to lymph vessels with fascial connective tissue. These primo vessels might be a functional integration in the lymph system.

A primo vessel was observed in the abdominal cavity in the lung cancer mouse model, and its function as an extra metastatic path was observed. In this work, we found a primo vessel accompanying a blood vessel emanating from a tumor in the skin. We also presented simple and efficient criteria to distinguish a primo vessel from a blood or a lymph vessel and from a nerve. The criteria for using DAPI and Phalloidin will be useful in clinical situations to find and identify the primo vessels among the blood vessels, lymph vessels, or nerves in the tissue surrounding a tumor such as a melanoma or breast cancer.

Occlusion of the thoracic aorta (AO) in dogs with a constant volume right ventricular extracorporeal bypass increased cardiac output (Q) by 43% and mean arterial pressure by 46%, while mean systemic pressure (MSP) was unchanged. We compared AO with occlusion of the brachiocephalic and left subclavian arteries (BSO) which decreased cardiac output by 5%, increased mean arterial pressure by 32%, and increased MSP by 11%. We feel these results confirm that AO elevates preload by transferring blood volume from the splanchnic veins to the vascular system drained by the superior vena cava. If the heart is competent to keep right arterial pressure at or near zero, this increase in preload will elevate Q above control levels. Comparing our data with results of other authors who have not controlled right atrial pressure, emphasizes the importance of a competent right ventricle in allowing venous return to determine Q.

BACKGROUND: Structural features of the patients vascular system can cause unintended complications when providing vascular access and can disorient the specialist in assessing the location of the installed catheter. This study aimed to demonstrate anatomical features of the vascular system of the superior vena cava and diagnostic steps when providing vascular access in a child. CASE REPORT: Patient K (3 years old) was on planned maintenance of long-term venous access. Preliminary ultrasound examination of the superior vena cava did not reveal any abnormalities. Function of the right internal jugular vein under ultrasound control was performed without technical difficulties; a J-formed guidewire was inserted into the vessel lumen. X-ray control revealed its projection in the left heart, which was regarded as a technical complication, so the conductor was removed. A further attempt to insert a catheter through the right subclavian vein led to the same result. For a more accurate diagnosis, the child underwent computed angiography of the superior vena cava system. Congenital anomalies of the vascular system included aplasia of the superior vena cava and persistent left superior vena cava. Considering the information obtained, the Broviac catheter was implanted under ultrasound control through the left internal jugular vein without technical difficulties with the installation of the distal end of the catheter into the left brachiocephalic vein under X-ray control. CONCLUSION: A thorough multifaceted study of the vascular anatomy helps solve the anatomical issues by ensuring vascular access and preventing the risks of complications.

Xiao Chai Hu Tang (XCHT), a compound formula originally recorded in an ancient Chinese medical bookShanghanlun, has been used to treat chronic liver diseases for a long period of time in China. Although extensive studies have been demonstrated the efficacy of this formula to treat chronic hepatitis, hepatic fibrosis, and hepatocarcinoma, how it works against these diseases still awaits full understanding. Here, we firstly present an overview arranging from the entire formula to mechanism studies of single herb in XCHT and their active components, from a new perspective of “separation study,” and we tried our best to both detailedly and systematically organize the antihepatocarcinoma effects of it, hoping that the review will facilitate the strive on elucidating how XCHT elicits its antihepatocarcinoma role.

We have experienced two cases of DIC following infusion of ascitic fluid from the peritoneal cavity to the vascular system. We have studied the etiology of this DIC. So, FDP, endotoxin, coagulant factors and procoagulant activity were investigated in ascitic fluid of 11 hepatic cirrhosis cases and 15 cancer cases.Method and Result; FDP in ascites were more included than in plasma. Endotoxin were positive in about 60% of ascitic fluid. The coagulant factors were recognized a littile except VUI-factor. Only ascitic fluid ded not clott the fibrinogen and did not affect the platlate aggregation. The procoagulant activities were measured by clotting times which the normal plasma (0.lcc) was added with the ascitic fluid or buffer (0.1cc), after 3 minutes incubation, and then added with 1/40 M Cacl2 (0.1cc).The clotting time was shortened in the ascitic fluid than buffer (buffer 120.7 ± 7.9 sec, Cancer 82 ± 23.8 sec., cirrhosis 91.4 ± 16.5 sec), and both VII and VIII deficient plasma was shortened too, but X dificient plasma was not coagulated. Also FDP and endotoxin did not shorten the clotting time of normal plasma. Experimentally, the ascitic fluid in dog by binding vena cava in ferior and the ascitic fluid in rat by transplantation of tumor cells shortened the clotting time. Conclusion; Coagulant, fibrinolytic and procoagulant factors were existed in ascitic fluid. We think that DIC induced by ascitic fluid are due to this procoagulant factor and this procoagulant factor may be not tissue - thromboplastin only.

The cerebral vascular system services the constant demand for energy during neuronal activity in the brain. Attempts to delineate the logic of neurovascular coupling have been greatly aided by the advent of two-photon laser scanning microscopy to image both blood flow and the activity of individual cells below the surface of the brain. Here we provide a technical guide to imaging cerebral blood flow in rodents. We describe in detail the surgical procedures required to generate cranial windows for optical access to the cortex of both rats and mice and the use of two-photon microscopy to accurately measure blood flow in individual cortical vessels concurrent with local cellular activity. We further provide examples on how these techniques can be applied to the study of local blood flow regulation and vascular pathologies such as small-scale stroke.
