[Laparoscopic management of the prostatic utricle cyst in a 4-year-old child].

The article present the clinical observation of 4 year old boy with scrotal hypospadias. Previous surgery management had unsatisfactory results due to complications of the cyst of the prostatic utricle. Laparoscopic removal of the cyst of the prostatic utricle was performed.

[The influence of continuous low-intensity laser radiation at the red (635 nm) and green (525 nm) wavelengths on the human mesenchymal stem cells in vitro: a review of the literature and original investigations].

Unlabelled: Low-intensity laser radiation can be used as one of the methods for the non-specific regulation of the human mesenchymal stem cell (MSC) activity at the preliminary stage of their in vitro cultivation. The objective of the present study was to estimate the influence of the limiting regimes of continuous low-intensity laser radiation (CLIR) of red (635 nm) and green (525 nm) spectra.

Material And Methods: The adhesive culture of human mesenchymal stem cells obtained from a donor's umbilical cord tissue was used in the experiments (following 4 passages).

[Catecholamines and their metabolites in children with Asperger and Kanner syndromes].

Children with Asperger and Kanner syndromes in the stable state demonstrate similar decrease in plasma norepinephrine. In the aggravated state, these changes become more expressed and are characterized by a decrease in plasma tyrosine, norepinephrine, normetanephrine and by an increase in dopamine and homovanylic acid and a decrease in excretion of norepinephrine and an increase in excretion of homovanylic acid, epinephrine and MHPG. Only in children with Kanner syndrome in the aggravated state plasma MHPG increases, excretion of tyrosine decreases and excretion of normetanephrine increases.

[Amino acids and their metabolites in blood and urine of children with minimal cerebral dysfunction].

The following changes were found in children in the minimal cerebral dysfunction: the hypoaminoacidemia and hypoaminoaciduria with decrease of glutamate and aspartate, their amides, methionine and serine in the blood and urine; decrease of lysine, taurine, tyrosine, catecholamines and serotonin in the blood; increase of GABA and glycine in the blood; increase of xanthurenate, proline and cysteine in the urine. The ratio excitatory/inhibitory mediatory amino acids decreased significantly. The ratio essential/nonessential amino acids and concentrations of amino acids, transporting by x-AG, beta and A/ASC systems, decrease in the blood; majority of transporting systems in the kidney functions augmently.
