In this research, we investigated the effect of tumor growth on blood flow through a micro channel by formulated the governing model with the assumption that blood is an incompressible, eclectrially conducting fluid which flow is caused by the pumping action of the heart and suction. The governing model was scaled using some dimensionless variables and the region of the tumor was obtained from Dominguez [1] which was incorporated in our model. The model is further reduced to an ordinary differential equation using a perturbation condition. However, the ordinary differential equation was solved using method of undermined coefficients, and the constants coefficients obtained via matrix method. Furthermore, the simulation to study the effect of the pertinent parameters was done suing computation software called Mathematica. It is seen in our investigation that the entering parameters such as magnetic field parameter, the Reynolds number, womersley number, oscillatory frequency parameter, and permeability parameter affect the blood velocity profile in decreasing and increasing fashion.

The liver arises from the foregut-midgut junction. It is contained in the Glisson capsule, and the falciform ligament attaches the liver to the anterior abdominal wall. Hepatocytes perform approximately 500 functions. Chronic hepatitis C, alcoholic liver disease, and nonalcoholic steatohepatitis may cause cirrhosis and give rise to liver failure and potentially HCC. MRI, CT, and US are helpful for determining the extent of cirrhosis and detecting ascites, tumors, and blood flow. Fifty percent to 80% of the liver can be resected if the remainder functions well. Liver resections may bleed, leak bile, or lead to infection.

Abdominal wall endometriosis is a common endometriosis, which is located outside the endometrium, such as the myometrium or subcutaneous fat layer of the abdominal wall, forming a mass, active and infiltrating into the surrounding tissue, accompanied by menstrual pain, and seriously affecting the quality of life of patients. With the increasing operation of caesarean section and other traumatic operations, the incidence rate of abdominal wall endometriosis is increasing. Because of the variety of clinical manifestations of abdominal wall endometriosis, there are many kinds of diagnostic methods. Choosing the appropriate diagnostic methods to confirm abdominal wall endometriosis has become the primary work of diagnosis and treatment of abdominal wall endometriosis. This paper discusses the clinical value of high frequency colour doppler ultrasound in the diagnosis of abdominal wall endometriosis. Compared with the diagnosis of ordinary ultrasound and high frequency colour doppler ultrasound, the location, shape, size, boundary, internal echo, blood flow velocity, blood flow resistance and other parameters of the mass in the focus were observed. It is proved that the application of high-frequency colour doppler ultrasound can greatly improve the ultrasonic diagnosis rate of abdominal wall endometriosis, and it is non-invasive, radiation-free, low price, easy for patients to accept. It provides a high value clinical diagnosis basis for the early detection and treatment of abdominal wall endometriosis.

The aim: Of work is to determine changes in blood flow in the vessels of the anterior abdominal wall that occur after plastic surgeries in order to improve the results of operations and to develop new methods for the prevention of complications. Materials and methods: The study was conducted in 132 patients. Patients were divided into 2 groups: main group 64 and control group 68 patients. Main group has patients who underwent abdominoplasty in combination with liposuction; control group has patients who underwent abdominoplasty without liposuction. In both groups we make different simultaneous operations. Laser Doppler Flowmetry and Ultrasonic Doppler Flowmetry were performed to determine the blood flow indices in the flaps. Results: Liposuction volumes averaged 3.57 ± 0.74 liters of lipoaspirate. In the main group there were totaly 4 complications, in the control group complications developed in 9 patients. Comparing daily indicators between the two groups, no statistically significant difference in the dynamics of MI changes was found during the entire study period (p = 0.767). Increase in caliber of vessels, on average, from 1.55 ± 0.8 mm in the preoperative period to 1.68 ± 0.75 mm on the 14th day of the postoperative period was statistically significant (p < 0.05). Conclusions: The combination of abdominoplasty with liposuction and simultaneous operations does not lead to greater development of complications and allows to achieve good aesthetic results.
