This study compared the hematological characteristics of diploid and triploid of jundia, Rhamdia quelen juveniles, an important freshwater fish cultured in south Brazil. Hematological morphometry of erythrocytes were determined in blood smears under a light microscope. The blood was used to measure the number of red blood cells (RBC) with a hemocytometer Neubauer chamber, and the numbers of whi...
Ca(2+) is a pivotal signal in human pulmonary artery smooth muscle cells (PASMCs) proliferation. Capacitative Ca(2+) entry (CCE) via the store-operated channel (SOC), which encoded by the transient receptor potential (TRP) gene, is an important mechanism for regulating intracellular Ca(2+) concentration ([Ca(2+)](i)) in PASMCs. Sildenafil, a potent type 5 nucleotide-dependent phosphodiesterase ...
The complete blood count (CBC) with leukocyte differential count (LDC) is a powerful tool to diagnose and monitor disease progression and therapy; it is one of the most ordered laboratory tests. Since Dr. Wallace H. Coulter introduced an automated cell counter in 1953,1 the laborious and timeconsuming eye-count method using a microscope and a hemocytometer has been replaced by automated analyze...
PURPOSE Previous reports have identified bacteria in the prostate of men with chronic pelvic pain syndrome. To examine whether prostatic bacteria are more prevalent among patients with chronic pelvic pain syndrome than among those without pelvic pain, we compared 4-glass urine test and prostate biopsy results. MATERIALS AND METHODS A total of 120 patients with types IIIa and IIIb chronic pelv...
This article describes a laboratory protocol for a multiweek project piloted in a new upper-level biology laboratory (BIO 426) using cell culture techniques. Human embryonic kidney-293 cells were used, and several culture media and supplements were identified for students to design their own experiments. Treatments included amino acids, EGF, caffeine, epinephrine, heavy metals, and FBS. Student...
Morus alba L. (MA) is a natural source of many compounds with different biological effects. It has been described to possess anti-inflammatory, antioxidant, and hepatoprotective activities. The aim of this study was to evaluate cytotoxicity of three flavonoids isolated from MA (kuwanon E, cudraflavone B, and 4'-O-methylkuwanon E) and to determine their effects on proliferation of THP-1 cells, a...
In the present study, the effect of intrauterine infusion of Zataria multiflora extract on the clinical endometritis was investigated. Vaginal examination, transrectal palpation and ultrasonography were used to inspect the genital tract at 30-40 days in milk and two weeks later the same approach was applied. Cows with clinical endometritis were randomly divided into three treatment groups: Z. m...
In this study we detect different levels of blood cells and hematological parameters in five creeks of Mahshahr region in North West of Persian Gulf with different levels of pollutant to characterized hematological response of Yellowfin seabream to environmental pollutant and undesirable materials. Numbers of Blood leukocytes was performed by a hemocytometer Neubauer under the light microscope....
The present report was designed to study the macrophage role and their association with percentage of spermatozoa showing DNA native, morphologically normal sperm and occurrence of antibody-coated spermatozoa. Human sperm samples from 31 patients were used in this study. All samples were evaluated for standard semen parameters according to World Health Organization criteria. The sperm heads wit...
PURPOSE To investigate the effect of PD98059, a mitogen-activated protein kinase (MAPK) inhibitor, on the replication of rat cultured retinal pigment epithelial (RPE) cells. METHODS Growth-phase rat RPE cells were exposed to various concentrations of PD98059 in serum-free F12 medium containing 0.1% dimethyl sulfoxide. Cell proliferation was assessed by cell counts using a hemocytometer. Cell ...
