Evidence of a vernal and pre nuptial spermatogenetic cycle in a mediterranean snake malpolon monspessulanus reptilia colubridae

, : Evidence of a vernal and pre nuptial spermatogenetic cycle in a mediterranean snake malpolon monspessulanus reptilia colubridae. Comptes Rendus des Seances de l'Academie des Sciences Serie III Sciences de la Vie 292(23): 1207-1210

Histological study of male sexual cycle in M. monspessulanus shows evidence that this snake is the only holarctic Colubridae not having an aestival spermatogenetic cycle. This snake, living in a non-arid Mediterranean area, is indeed the only one to show vernal spermatogenesis.

The aim of the present study is to reveal gestational age-related changes in sustained foetal tachycardia (SFT). 24 h fetal heart rate (FHR) recordings were made on 102 normal pregnant women in 30-41 weeks of gestation. SFT was defined as an incre...

The migratory and distribution pattern of A. caninum larvae in the different organs of Swiss albino mice infected s.c. with 500, 1000, 2000 and 4000 doses was investigated. Larval migration into the gastrointestinal tract, liver and lungs occurred...

But this apposition generally does not occur in civilized man. On the contrary the widespread tooth attrition which occurs in primitive man, is well established (1, 2,...

The biotransformation and cardiovascular effects of arachidonic acid (AA) were studied in the circulation of anesthetized dogs. Arterial blood was continuously bioassayed for arachidonate metabolites using the bloodbathed organ technique. AA (5-10...

However, both migration itself and flight capability reduce...
