To observe changes in blood pressure of dogs with hemorrhagic shock during infusion of 7 5% NaCl, five mongrel dogs were bled to MAP 5 33～6 7kPa and then kept at this pressure for 1 hour. Each dog received 7 5% NaCl solution (4ml/kg) intravenously and the infusion time was 2 min. The results showed that during the 2 min infusion period the systolic pressure (SP) was obviously higher than that before the infusion ( P

Objective To investigate the expression and localization of dopamine- and cAMP-regulated phosphoprotein of 32 000 (DARPP-32) in mouse kidney tissue. Methods The cellular localization of DARPP-32 in mouse kidney tissue was detected by immunoblot and immunohistochemistry. Results DARPP-32-like immunoreactivity was detected in the medullary thick ascending limb of the loop of Henle, the cortical proximal convoluted tubule, and collecting ducts in medullary rays. The renal tubules were enriched of Na+, K+-ATPase for sodium reabsorption. Conclusion The participation of DARPP-32 is a likely crucial step of the signal-transduction pathway of dopamine regulation on sodium reabsorption in renal tubule cells.

OBJECTIVE To find out the status about detection and drug resistance of Ureaplasma urealyticum(Uu) and Mycoplasma hominis(Mh) of urogenital tract infection in Shaoxing area of Zhejiang Province.METHODS The detections and drug sensitive tests of Uu and Mh adopting the reagent boxes produced by bioMerieux Company in France were made.RESULTS In 2678 samples of suspicious urogenital tract infection patients,980 samples cultured of mycoplasma were positive,and the positive rate was 36.6%.Among these cases,763 samples(28.5%) were Uu positive;116 samples(4.3%) were Mh positive.In the drug sensitive test,Uu and Mh were most sensitive to PRI,JOS,DOX and TET.To CFLX,OFL,ERY,CM and AM,they had the highest level of drug resistance.CONCLUSIONS The clinical therapy of mycoplasma infection ought to choose the appropriate antibiotics based on the results of the drug sensitive test of the laboratory.

The RAS (rat sarcoma) gene is one of the important oncogenes, and its mutation is present in about 30% human tumors. KRAS (kirsten rat sarcoma viral oncogene) is one of the three RAS subtypes, and KRAS mutations are more common than the mutations in other two RAS subtypes. In recent years, with the continuous research, new ideas have been provided for the treatment of cancers via targeting-KRAS. Efforts have been made to develop various KRAS inhibitors. Here, based on the mechanism of action, we classified KRAS inhibitors into two categories: inhibitors that directly target KRAS and inhibitors that indirectly act on KRAS. The representative KRAS inhibitors were summarized and introduced in this paper.
