The effect of mycotoxin (T-2 toxin) on catecholamines and Na+, K+-ATPase activities in rat epididymis has been evaluated. Dopamine and norepinephrine levels were significantly elevated in the caput and corpus regions whereas their levels remained unchanged in the caudal part of the epididymis. Na+, K+-ATPase activity was significantly increased in all the(More)
BACKGROUND Cytological examination of effusion fluid is a relatively easy and quick method for the diagnosis of primary or secondary malignancy. AIMS To analyze the cytological significance of cell cannibalism in malignant effusion samples. MATERIALS AND METHODS A retrospective review of 100 cases of malignant effusion was done. These 100 cases included(More)
OBJECTIVE MicroRNAs (miRNAs) are short regulatory RNAs that can modulate gene expression and function as negative regulators. Common genetic variants like single nucleotide polymorphisms (SNPs) in miRNA genes may alter their expression or maturation resulting in varied functional consequences in carcinogenesis. Therefore, we evaluated the genetic variants(More)
Daily oral administration of gossypol acetic acid (40 mg/kg body weight daily) resulted in a gradual decrease in the semen volume and sperm concentration. Fertility dropped to zero at the end of the treatment period. Activities of acrosin, hyaluronidase and angiotensin converting enzyme were also drastically decreased by the end of the treatment period. A(More)
BACKGROUND Fine needle aspiration (FNA) is a quick, minimally invasive procedure for evaluation of breast tumors. The Scarff-Bloom-Richardson (SBR) grade on histological sections is a well-established tool to guide selection of adjuvant systemic therapy. Grade evaluation is possible on cytology smears to avoid and minimize the morbidity associated with(More)
In developing countries, diagnosis of breast carcinoma is still made on fine-needle aspiration cytology (FNAC). For the resource-poor settings, FNAC is cheaper, less invasive and can sample different areas of the lesion compared with core needle biopsy. The role of breast FNA is usually limited to just categorize the lesion as benign or malignant.(More)
OBJECTIVE Circulating tumor cells are isolated tumor cells in the peripheral blood that serve as important prognostic indicators for many kind of tumors. The study was conducted to know the rate of detection of circulating tumor cells among breast cancer patients in comparison with benign breast diseases and control subjects and to know the association(More)
Effect of exogenous serotonin and blockade of its endogenous production on Angiotensin Converting Enzyme (ACE) in testes and epididymis was studied. Serotonin (30 mg/kg) and p-chlorophenylalanine (100 mg/kg) were injected for 4 and 3 days respectively. Serotonin reduced the weights of testes, seminal vesicle and ventral prostate whereas epididymal weight(More)
