Serum progesterone in nonpregnant women. II. Correlation between serum progesterone and some other luteinization parameters

Correlation between serum progesterone concentration, urinary pregnanediol excretion, endometrial biopsies, vaginal cytology, and basal body temperature was performed to determine the most dependable method for assessing the presence of a functioning corpus luteum. Vaginal cytology was not completely reliable as it had relatively poor correlations. A biphasic basal body temperature was always associated with a rise of progesterone to luteinization range, but a monophasic chart did not necessarily indicate anovulation. This fallacy, together with difficulties in recording and interpretation, made basal body temperature not totally accurate for assessing luteal activity. Premenstrual endometrial biopsies gave the best correlation with hormonal assays. It is thus concluded that serum progesterone determination and properly interpreted endometrial histology are the most accurate diagnostic luteinization parameters. © 1974.SCOPUS: ar.jinfo:eu-repo/semantics/publishe

Comparison of bovine rotavirus strains by plaque assay

Using plaque assay on MA 104 cells, four strains of bovine rotavirus were compared: the attenuated American strain NCDV, and three virulent strains isolated in Canada (PQ) or in Belgium (S14 and S 77). The attenuated strain (NCDV) formed smaller plaques than the three others. The plaque size may thus be used as a marker for this strain. The Belgian strain S 77 formed the largest plaques and no significant differences could be found between the Canadian strain PQ and the second Belgian strain S 14. On BSC-1 cells, the Canadian strain PQ formed much smaller plaques than on MA 104 cells. © 1981

Die Empfindlichkeit verschiedener Taubenherpes-virusstämme gegen Trinatriumphosphonoformat

The susceptibility to trisodium phosphonoformate of five strains of pigeon herpesvirus (Pigeon Herpesvirus 1, PHV) was compared by measuring the mean plaque size variations in the presence of different concentrations of the compound. Significant differences in their susceptibility to phosphonoformate were observed, but none of them was found to be naturally resistant. This finding may be of significance for a possible clinical application in the treatment of pigeon herpesvirus infection. © 1981, Taylor & Francis Group, LLC.

Dieses Ergebnis könnte bei einerevtl. klinischen Anwendung zur Behandlung der Taubenherpesvirus-Infektion von Be-deutung sein

Susceptibility of the dromedary (Camelus dromedarius) to rotavirus infection

Camelus dromedarius) is susceptible to rotavirus infection. Among 55 dromedary sera collected in Morocco, 27, it is to say about half of them, possessed anti-rotavirus antibodies. The dromedary is the refore susceptible to rotavirus infection, like many other animal species.Camelus dromedarius) est réceptif à l’infection par rotavirus. Sur 55 sérums de chamelons récoltés au Maroc, 27, soit la moitié à peu près, contenaient des anticorps dirigés contre ce virus. Le dromadaire est réceptif a l’infection par le rotavirus, comme la plupart des autres espèces animales
