Lack of evidence for meteorological effects on infradian dynamics of testosterone.

Climatic factors are known to influence the endocrine system. Previous studies have shown that circannual seasonal variations of testosterone might be partly explained by changes in air temperature. Whether infradian variations are affected by meteorological factors is unknown.

[Effect of weather on the occurrence of cerebral stroke].

In this paper a set of medical and meteorological data for the period of years 1985-1987 is elaborated and statistically evaluated in order to find correlations between daily occurrence of ischemic and haemoragic forms of cerebral stroke and particular biotropic types of weather. For tracing we gathered clinical medical data from eight health-service institutions in Bratislava. We compared both annual and seasonal courses of biometeorological types of weather in the investigated period with annual and seasonal courses of the followed sickness rate.
