The mechanism of urinary excretion of sulfadiazine was investigated in the dogs by means of stop-flow technique Results of experiments were summarized as follows; 1. The ratios of U/P sulfadiazine to U/P creatinine $(U/P_{SD}:U/P_{cr})$ were always lower than 1 in all nephrons, showed a minimum in the proximal area. 2. $U/P_{SD}:U/P_{cr}$ were not affected by Probenecid or 2.4-DNP, whereas increased significantly by administration of sodium bicarbonate. 3. Probenecid did not alter the stop-flow patterns in alkalotic dog too. 4. $C_{SD}$ (clearance of sulfadiazine ) was appreciably influenced by change in urinary PH, or flow rate. All evidences lead to the conclusion that sulfadiazine reabsorption is passively transported by proximal tubules. No clue for active process, either secretory or reabsorptive, was obtained.

Two of the degradation products of alachlor in soil. product 1, 2,6-diethyl-N-(methoxymethyl) acetanilide and product 2,2-hydroxy-2',6'-diethyl-(methoxymethyl) acetanilide were synthesized from alachlor reacting with 3N-hydrochloric acid in the presence of zinc powder at room temperature and a saturated sodium bicarbonate solution at $90^{\circ}C$ for 78 hr, respectively. At the concentrations of both $5{\times}10^{-4}M\;and\;1{\times}10^{-3}M$, product 2 exhibited almost the same phytotoxicity to rice seedlings, in particular, as alachlor, whereas product 1 lost its phytotoxic effectiveness. It seems that substitution of chlorine atom by hydroxyl group did not affect the phytotoxicity of alachlor, whereas substitution by hydrogen atom did.

This study was conducted to investigate chemical properties, quality stability and utilization of approved sardine surimi(ASS) which is developed our laboratory. The product yield of the ASS was about 3 times higher than that of usual sardine surimi(SS). The proper addition concentration of sodium bicarbonate was 0.1% for the neutralization of the ASS. The content of salt soluble protein nitrogen in the ASS was about the half of that in the SS, while the content of water soluble protein nitrogen was 2.4 times higher in ASS. The total amount of free amino acids in the ASS was about 11 times higher than that of the SS. Predominant free amino acids in the ASS were histidine, taurine, glutamic acid and alanine, and those four amino acids occupied 94% of total amount of free amino acids. During cold storage at 21oC for 6 months, the quality of ASS was more stable than that of SS in judging from changes of water soluble and salt soluble protein nitrogen, AV and POV. Quality of fish burger, fish sausage and fried fish paste processed in accordance with commercial processing preparation using the ASS or SS exclusively and mixtures which other white meat fish surimi(alaska pollack, hair tail and sole) were proportionallly added to each of two types of sardine meat were evaluated. In case of fish burger, the product processed from the ASS only were superior.

In this study, in order to examine whether salt and heat shock stress would alter or not contraction and relaxation of isolated rat aorta. Under anesthesia with sodium pentobarbital(50 mg Kg$^{-1}$ i.p.), male Sprague Dawley rats weighing 300-330 g were subjected to 0, heat shock combined salt stress, where as the sham group was left at modified Krebs-bicarbonate solution. To measure contractile response of vascular ring preparation isolated from rat was determined in organ bath and was recorded on physiograph connected to isometric transducer. And the strip was checked for expression of heat shock protein(Hsps) by means of western blotting. The combination group of heat and 50 mM NaCl group increased vascular contractility, and the heat and 150 mM NaCl group decreased vascular contractility for 5 hours, and then recovered for 8 hours compared to that of control. Expressin of Hsp 70 of vascular muscle of rat aorta more increased by combination of heat and NaCl treatment than those of single treatment of heat or NaCl treatment, and vascular Hsp 70 showed a little decrease at 8 hours compared at 5 hours. These result indicate that mixed environmental stress either increased or decreased in vascular contractility by combination of heat and NaCl concentration.

Two giant pandas, which come from China have been roared in Yong-in Farmland zoo since 1994. One of them, which is female and 2 years old showed anorexia, mucous diarrhea and severe abdominal pain. It revealed neutrophilia and hypokalemia which suggested inflammation and loss of electrolytes by diarrhea. The mucous material contained intestinal mucoid epithelim which was infected Gram negative bacilli and infiltrated with neutrophils. The antibacterial therapy with nafcillin and ampicillin was not successful. Yersinia entrocolitica was implicated as a causative organism in the occurrence of bacterial enteritis. This organism had resistance to ampicillin, chlorampenicol, cefalothin, tetracycline, trimetoprim-sul-famethoxazole, erythromycin, gentamicin, kanamycin, carbanicillin and danofloxacin. It responded to the simultaneous administration of cefopherazone, flunixin-meglumine, physiological saline, Lactate Rainger's solution, sodium bicarbonate, KCL and vitamins and recovered after a period of 30days.

Due to the fact that an inactivated anthrax vaccine may lark its immunogenicity and stability of immunogen a number of spore vaccines were exclusively used worldwide. In these studies a number of important factors were emphasized to achieve the following: selection of non or less allergic strain of anthrax bacillus, capsulation of bacteria. obtaining of non sporulating but vegetative organisms, adequate inactivation of B. anthraccis by means of formalin, adsorption of immunogen to aluminum hydroxide gel. Non or less allergic strains of anthrax bacillus which is inactivated with formalin was selected by a hyperimmunization and shock test in rabbits. Obtaining capsular material and vegetative immunogen, a virulent anthrax organisms were cultivated on sodium bicarbonate medium with of without adding of l-alanine in which B, anthracis grew luxuriantly without forming spores. Inactivation was carried out at $37^{\circ}C$ water bath for 3 days after the bacterial culture was mixed with formalin, in a final concentration of two per cent of formalin. Aluminum hydroxide gel was added to the mixture of anthrax and blackleg bacterin. Vaccines were injected guinea pig via subcutaneous or intramusoular route and challenged after three weeks and the possibilities of protection was tested. Throughout the studies. the above mentioned vaccines possibly protected the vaccinated guinea pigs more than 80 per cent compared to that of the controls. This experimental results strongly suggest that the vaccine may possibly applicable to bovine.

Currently, the optimal resuscitation fluid remains debatable. Therefore, in the present study, we designed a trometamol-balanced solution (TBS) for use as a resuscitation fluid for hemorrhagic shock. Hemorrhagic shock was induced in 18 male Wistar-Kyoto rats, which were assigned to normal saline (NS), Ringer's solution (RS), and TBS groups. During the hemorrhagic state, their hemodynamic parameters were recorded using an Abbott i-STAT analyzer with the CG4+ cartridge (for pH, pressure of carbon dioxide, pressure of oxygen, total carbon dioxide, bicarbonate, base excess, oxygen saturation, and lactate), the CG6+ cartridge (for sodium, potassium, chloride, blood glucose, blood urea nitrogen, hematocrit, and hemoglobin), and enzyme-linked immunosorbent assay kits (calcium, magnesium, creatinine, aspartate aminotransferase, alanine aminotransferase, bilirubin, and albumin). Similar trends were found for the parameters of biochemistries, electrolytes, and blood gas, and they revealed no significant changes after blood withdrawal-induced hemorrhagic shock. However, the TBS group showed more effective ability to correct metabolic acidosis than the NS and RS groups. TBS was a feasible and safe resuscitation solution in this study and may be an alternative to NS and RS for resuscitation in hemorrhagic shock patients without liver damage.
