Aim. To assess the morphology of circulating red blood cells in patients with stage III ovarian cancer. Methods. The object of the study was the peripheral blood erythrocytes of primary patients with ovarian cancer (n=25) who had stage III according to International Federation of Gynecology and Obstetrics. Patients were examined in the gynecological department of Ulyanovsk Regional Clinical Oncology Center. The control group included 25 somatically healthy women. Morphological studies were performed using light microscopy. The number of red blood cells with an unchanged and altered shape was expressed as a percentage. By the method of atomic force microscopy, the topology and rigidity of red blood cells was studied. Results. A statistically significant decrease in the number of circulating blood erythrocytes was found in patients with ovarian cancer compared to somatically healthy women. At the same time, the number of discocytes is markedly reduced while the number of morphologically altered forms: echinocytes, stomatocytes, spherocytes and erythrocyte rigidity are increased. Conclusion. With the appearance of altered forms of red blood cells and increase of the transformation index and erythrocyte rigidity in patients with stage III ovarian cancer, total number of red blood cells decreases in circulating blood compared to somatically healthy women.

The problem of structural changes in peripheral blood erythrocytes in patients with chronic heart failure in combination with vitamin D deficiency during exercise stress remains insufficiently studied. Vitamin receptors are located on smooth myocytes, endothelial cells, cardiomyocytes and blood cells. It affects the state of the cell membrane, the contractile function of the myocardium, the regulation of blood pressure, cardiac remodeling and reduction of left ventricular hypertrophy. Therefore, it is important to assess the level of vitamin D in blood plasma in individuals with chronic heart failure and to identify the effect of its deficiency on the state of peripheral red blood cells when performing a 6-minute walk test. A total of 75 patients of the main group with chronic heart failure stage II A, I–II functional class with different levels of vitamin D deficiency were examined. The control group included 25 patients with chronic heart failure stage II A, functional class I–II without signs of vitamin D deficiency. The average age of patients was 57.5 ± 7.5 years. All patients were asked to undergo the 6 minutes walking test. The level of total vitamin D in plasma was determined by enzyme immunoassay. Morphological studies of erythrocytes were performed on the light-optical and electron-microscopic level. The obtained results showed that patients of the main group with chronic heart failure had a decrease in vitamin D by 2.2 times compared with the control group. Correlation analysis showed a directly proportional relationship between vitamin D deficiency and the number of red blood cells of a modified form and red blood cells with low osmotic resistance. Dosed exercise stress in patients with chronic heart failure against a background of vitamin D deficiency leads to an increase in the number of reversibly and irreversibly deformed erythrocytes and a decrease in their osmotic stability. This indicates a disorder in the structural integrity of their membrane and can have negative consequences for the somatic health of such patients.

Range Analysis

During Chronic Kidney Disease (CKD) development and progression emphasis is placed on structural-functional state of red blood cells. The aim of this paper is to examine red blood values and red blood cells morphological type in peripheral blood among children with CKD. 75 children with CKD aged 5-16 years were examined. The control group consisted of 25 healthy children of the same age range. Analysis of the morphometric parameters of red peripheral blood cells - mean volume (MCV) and erythrocyte diameter, mean content (MCH) and mean hemoglobin concentration in the erythrocyte (MCHC), were performed using a Gobas Micros (Roche) hematology counter. Smears were marked according to Romanovsky-Giemsa. Morphometric studies of red blood cells were carried out using the Morphology 5.2 program and red blood cell confocal microscopy on a LSM-710 Confocal Microscope, manufactured by Carl Zeiss. The tendency to poikilocytosis in CKD was confirmed. We identified that among children with CKD the distribution of red blood cells in diameter is disturbed, the content of microcytes increases, poikilocytosis is observed with an increase in the content of irreversibly transformed elements. The revealed features may serve as an additional criterion for the diagnosis of chronic kidney insufficiency at the early stage.

This work evaluated the effect of in vitro and in vivo treatment with ASA on the morphology of the red blood cells. Blood samples or Wistar rats were treated with ASA for one hour. Blood samples or animals treated with saline were used as control group. Blood smears were prepared, fixed, stained and the qualitative and quantitative morphology of red blood cells were evaluated under optical microscopy. Data showed that the in vitro treatment for one hour with ASA at higher dose used significantly (p<0.05) modified the perimeter/area ratio of the red blood cells. No morphological alterations were obtained with the in vivo treatment. ASA use at highest doses could interfere on shape of red blood cells.

The aim of the study is to increase the productive qualities of broiler chickens by including ultrafine silicon oxide into main diet. During the experiment, the biological effect of ultrafine silicon oxide on broiler chickens was estab-lished. Use of ultrafine SiO2 particles for poultry feeding contributed to an increase in the number of red blood cells and content of total protein and albumins. By the end of the experiment, the number of red blood cells in birds in-creased by 17.43% (P≤0.001) – in the blood of birds of the first experimental group, 16.51% (P≤0.01) – the second one, 20.80% (P≤0.001) – the third experimental and 21.71% (P≤0.001) – the fourth experimental group, compared with the indicator of the control group. The amount of total protein in blood serum of chickens of the first and the second experimental groups increased by 1.36-1.39 %, in the third and fourth ones there was a significant (P≤0.05) increase by 5.45 and 3.05%, respectively. The blood glucose content of chickens in the experimental groups is higher by 8.04-23.65% compared to this indicator with ones in the control group. During the experiment feed con-sumption per 1 kg gain of live weight decreased: in the first experimental group by 3.00 % in the second by – 0.50 %, the third – 6.00 % the fourth– by 4.50 %, compared to this with the control group. The chicken’s vibrancy of the first the experimental group was higher by 4.77 %, the second – by 6.20 %, the third – by 19.25 % and the fourth– by 11.59% than in the control one. Consequently, when converting the feed energy into the body energy of a broiler chicken, the energy conversion coefficient of the experimental group of poultry is higher than that of the control one by 7.16-21.76 %. Thus, the most optimal dose for further research was determined.

This study was carried out to investigate the effect of experimental infection by Escherichia coli on some blood parameters and histopathological changes in male rats to reach this objective twenty male rats (Rattus norvigicus) were divided into two groups, housed under same conditions of water, feed, temperature, light and humidity. The first one served as control group, while the second was experimentally infected with Ecoli by administration of 2ml / rat of (1×109) colony forming unit/ml of E-coli. Five days later blood were obtained from animals by cardiac puncture to measure the total and differential white blood cells count hemoglobin concentration packed cells volume red blood cells count, and thrombocytes count. One animal from each group was killed and histopathological examination was done for intestine kidney liver and spleen to detect the effect of infection on these organs. The results revealed a significant increase in total leukocytes count (P<005) in infected group while the differential count showed a significant increase in neutrophils and significant decrease in lymphocytes (P< 0.05) in same group. There were a significant decrease in hemoglobin concentration packed cell volume and non significant decrease in red blood cells count. While thrombocytes count showed a significant decrease in infected group compared with control group (P<0.05). The histopathological examination of infected male rats intestine was demonstrated mild diffuse inflammation which include increased numbers of neutrophile in tissue intraepithelial lymphocytes and goblet cells In kidney renal tubules showed extensive epithelial swelling with decreased lumen space and generalized necrotic changes with interstitial hemorrhage in renal cortex. In liver hepatocytes were swollen with decreased sinusoidal spaces and widely distributed necrotic foci were seen. There is extensive splenic necrosis with infiltration of leukocytes from white pulp to red pulp of spleen.

Genus Plasmodium

Background: Malaria is a systematic disease caused by a parasite called Plasmodium which is transmitted into the human blood via female Anopheles mosquito. Malaria in humans is caused by four species of protozoan parasites of the genus Plasmodium: P. falciparum, P. vivax, P. ovale, and P. malariae. The parasite enters the human body through a mosquito bite and travel to the very crucial organ, the liver, where they multiply and come back to the bloodstream and destroy red blood cells. Malaria causes symptoms that typically include fever, tiredness, vomiting, and headaches. In severe cases it can cause yellow skin, seizures, coma, or death. Symptoms usually begin ten to fifteen days after being bitten by an infected mosquito. In those who have recently survived an infection, reinfection usually causes milder symptoms. Objectives: Isolation of different species of malaria parasites. The prevalence of malaria parasite in India. Methods: The procedure follows these steps: collection of peripheral blood, staining of smear with Leishman’s stain and examination of red blood cells for malaria parasites under the microscope. Results: We observed the plasmodium species in peripheral blood smear. Conclusion: Worldwide, the number of cases of malaria caused by Plasmodium falciparum, the most dangerous species of the parasite, is on the rise.

Objective: To determine effect of citrullus lanatus juice on hemoglobin and Serum Glutamic Pyruvic Transaminase (SGPT) level. Study design and setting: It was an experimental study conducted on healthy rabbits for sixty days in the research department of pharmacy University of Karachi. Methodology: Current study was planned to evaluate effect of Citrullus lanatus juice on red blood cells, hemoglobin and liver enzyme. 60 days study was performed at 2 different doses i.e 3and 6ml/kg on rabbits. These rabbits were from either gender and were divided into 3 groups their weight ranges from 1200 to 1800 grams. Group A is control group (Normal saline 6ml/kg), Group B is treated group (3 ml/kg), Group C is treated group (6ml/kg). After taking mean of all values they are compared with control group. Significance of mean can be estimated by Tukes Post Hoc Test. P<0.05 estimated as significant. Results: It was found that count of red blood cells rises significantly along with rise in hemoglobin level. As far as liver enzyme serum glutamate pyruvate transaminase (SGPT) was concerned its concentration decreases slightly. Conclusion: Citrullus lanatus juice contain ingredients which are important for RBC hemoglobin and synthesis .It also contains important antioxidants that have organoprotective role due to which SGPT level decreases even in healthy animals as compared to control groups
