The reported occurrence of synergistic false-positive coliform reactions on M-Endo MF medium was investigated. The objectives of the study were (i) to isolate populations of bacteria which produced such false-positive reactions, (ii) to determine whether false-positive sheen reactions are a result of synergistic interaction, and (iii) to determine the metabolic intermediates involved in false-p...

Dextran, with a minimal molecular weight of 40,000, can pass in and out of the corneal endothelium during storage in M-K medium. Results suggest that the degree of penetration of dextran depends on the length of storage and the condition of the endothelium.

background: previous studies reported many discrepancies about the effects of corpus luteum (cl) and ovarian follicle size on the developmental competence of oocytes. objective: the aim of this study was to investigate the effects of cl and different size of follicle on the developmental potential of bovine oocytes. materials and methods: after ovarian classification based on presence or absenc...

objective: exercise activity could be an amendment to polycystic ovary syndrome (pcos). however the acute and chronic effects of various exercise intensities on serum leptin levels are ambiguous. this study investigates the acute and chronic responses of various intensities of exercise on serum leptin levels and weights of female rats with pcos. methods: in this semi-empirical study, 80 adult w...

Chalquest and Hayflick media with and without ammonium reineckate were compared for isolation of Mycoplasma pulmonis from the nasopharyngeal ducts, tracheobronchial trees, and middle ears of 66 naturally infected rats. The results show that 92% (366 of 396) of the samples were positive for M. pulmonis in Chalquest medium with and without ammonium reineckate and 66% (260 of 396) were positive in...

The qualitative morphologic study of the effects of organophosphate agents on development of neural cells in culture is a promising approach as a primitive step for further physiologic, electro physiologic and molecular investigation. Parathion is an OP (Organophosphate) used as an agricultural insecticide. Improper handling of this agent causes poisoning characterized by convulsive seizures, w...
