[Microcirculation in patients with paranoid schizophrenia].

Aim: To study microcirculation in patients with paranoid schizophrenia by laser Doppler flowmetry.

Material And Methods: Fifty-three patients at the age from 18 to 38 years with a diagnosis of 'paranoid schizophrenia' (F20.0) were examined in the acute psychotic state and after 3 weeks of therapy.

[Endothelial dysfunction is a target for combination antihypertensive therapy in hypertensive patients with type 2 diabetes mellitus].

Aim: To evaluate the impact of combination antihypertensive therapy with lisinopril + amlodipine (Ekvator) on endothelial dysfunction in patients with hypertension and concurrent type 2 diabetes mellitus (T2DM).

Subjects And Methods: The trial enrolled 30 patients aged 40 to 65 years with Stages II-Ill hypertension concurrent with T2DM. All the patients received combination antihypertensive therapy with lisinopril + amlodipine (ekvator) for 12 weeks.

Reproductive hormone levels in men exposed to persistent organohalogen pollutants: a study of inuit and three European cohorts.

Objective: Persistent organohalogen pollutant (POP) exposure may have a negative impact on reproductive function. The objective of this study was to assess the impact of POP exposure on the male hypothalamo-pituitary-gonadal axis.

Participants: Participants included 184 Swedish fishermen and spouses of pregnant women from Greenland (n = 258), Warsaw, Poland (n = 113) , and Kharkiv, Ukraine (n = 194).

Semen quality and exposure to persistent organochlorine pollutants.

Background: Inconsistent results have been found in previous human studies on male reproductive toxicity of persistent organochlorine pollutants. The majority of studies have been conducted among selected populations of infertility clients or among occupational cohorts including a limited number of participants.

Methods: We conducted a cross-sectional study of semen quality and serum concentration of 2,2',4,4',5,5'-hexachlorobiphenyl (CB-153) and 1,1-dichloro-2,2-bis (p-chlorophenyl)-ethylene (p,p'-DDE) among 763 men.

Quality control workshops in standardization of sperm concentration and motility assessment in multicentre studies.

Semen quality has been reported to vary markedly between different regions. To properly assess the differences among countries a minimization of the variation among centres in the assessments of sperm quality is essential. We here report on the training and two subsequent follow-up workshops on assessments of sperm concentration and motility.
