The pharmacologic effects of verapamil (Ver) and phenylephrine(PE)on the smooth muscle of the human fallopian tube in vitro and their relationship to the stages of menstrul cycle were observed respectively. The results demonstrated that both the ampulla and isthmus of the human fallopian tube produced a contractive response to PE, which was antagonized by phentolamine. The PD_2 and PA_2 valucs were larger during the proliferative phase than during the secretory phase in the circular and longitudinal muscle of the isthmus. But there was no difference between the circular and longitudinal muscle. Ver supressed the activity of the human fallopian tuba smooth muscle and antagonized the effects of PE.The PD_2~' values were larger during the secretory phase than during the prolifertive phase. These pharmacologic characte risties of the tube indicated that d-adrenoceptor of the longitudinal muscle of the is thmus may be important, like the circular muscle in the regulation of ovum transport.

The effects of DL-tetrahydropalmatine andsinomemine on the activity of oviduct smooth mus-cle and ovum transport in rabbits are reported inthis paper. The results indicate that the two a-gents apparently inhibit the contractile activity ofoviduct isthmic smooth muscle of rabbit in vitroand decrease the frequency, amplitude, tensionand curve areas of the contraction. The contractileffect induced by noradrenaline is also inhibited re-markbly by them. In addition, DL-THP and Sino.can delay ovum transport in rabbit oviduct after ivHCG 48 h. It is suggested that the inhibition ofactivity of oviduct smooth muscle may be one ofthe important causes of delaying egg transportcaused by the two agents.

Calcium blockers verapamil ( VER ) and nifedipine ( NIF ) appa-rentely inhibited the spontaneous activity of isolated rat oviduct. The 5 min contractile curve aera determined by integrator,after eithet VER or NIF effected, was smaller than that before,with dose dependence.In rats pregnanant for 3d VER and NIF accelerated ovum transport through oviduct. The number of ovum recovered from uterus in test group was more than that in control group. Paired experiments showed VER and NIF having no anti-implantation action.

Objective To evaluate the usefulness and necessity of spiral computer tomography (SCT) and color-Doppler ultrasonography (CDU) in primary hepatocellular carcinoma (HCC) after transcatheter arterial chemoembolization (TACE). Methods Plain SCT scanning and contrast-enhanced SCT scanning or / and CDU were performed for 68 HCCs before and four weeks after TACE. Factors related to overall survival (OS) were observed as tumor size necrosis, relapse, lipiodol deposition, blood supply of the survived tumor. Images of SCT and CDU were compared. Clinical significance obtained through direction of diagnostic radiology was evaluated. Results 139 masses observed in the 68 cases were shranked or necrotized in a different degree after TACE. 8 new metastasized massed were observed. Complete lipiodol deposition was observed in 27 masses and no lipiodol deposition in 14 masses. As for estimating the types of lipiodol deposition, SCT was better than CDU with significant difference. SCT could indirectly estimate the blood supply of tumor after TACT through 3 dynamic enhanced phases, while CDU could directly visualize the hemodynamic changes of liver, internal and peripheral parts of the tumor. Conclusion TACE is an effective way to treating HCC. SCT scanning and / or CDU are necessary before and after TACE to estimate the imaging changes so as to provide indispensable information for the best therapeutic schedule in the future.

Recently, a novel atypical porcine pestivirus (APPV) in pig was reported. In this study, two APPV strains, APPV-China/GZ01/2016 (GZ01) and APPV-China/GD-SD/2016 (GD-SD), were identified in two newborn piglet herds with congenital tremor from China. The open reading frame of the two strains shared an 83.5% nucleotide identity. Phylogenetically, the APPV strains were placed into two groups: GZ01 belonged to group I and GD-SD belonged to group II. A high viral load was detected in the cerebellum (quantification cycles < 26). Further studies should be carried out to thoroughly elucidate the development of congenital tremors caused by APPV.
