ABSTRACT
The objectives of this present study were to assess the effects of varying dilutions, pH, temperature and cations on spermatozoa motile parameters (SMPs) in fish Larimichthys polyactis. Optimal SMPs were observed when semen was diluted in artificial seawater (ASW) at a ratio of 1 to 100, with temperature of 10oC and pH 8.0. The spermatozoa of L. polyactis were immotile in distilled water and motile in solution containing different cations. Maximum SMPs were obtained in each solution containing 0.4 mol NaCl, 0.4 mol KCl, 0.2 mol CaCl2 and 0.2 mol MgCl2. This study provides baseline knowledge of L. polyactis spermatozoa sensitivity of pH, temperature and cationic effects.
ABSTRACT
27 patients with the diagnosis of bone fractures of the limbs with injury of peripheral vessels were treated in Viet Tiep Hospital, Hai Phong city from January 2001 to November 2002. Their majority was male persons of productive age and the main cause was traffic casualties 74%, among them underwent early operation within 6 hours. 6 patients underwent a bone combination with intraspinal nail or Kirchner needle. Among 23 preserved cases, only in 8 cases, the function of the limbs was well rehabilitated, the rest were moderate and bad. In 4 cases, it must undergo an amputation at 2nd time because the late diagnosis and had been missing.
