Gene expression of specific parts of CNS in a rat model for transgenerational transmission of drug addiction.
Radilová, Kateřina ; Černá, Marie (advisor) ; Rothová, Olga (referee)
Methamphetamine (MA) is a drug often abused by drug-addicted women and also is the mostly used drug in the Czech Republic. This drug crosses the placental and hematoencephalic barriers easily and therefore it can negatively affect not just mother herself, but also the development of the fetus. Even though there have been several published studies evincive negative effects of MA to posterity of drug-addicted mothers, the most critical term during pregnancy for the fetus remains unknown. In this study are examined CNS structures, which are directly influenced by methamphetamine action. Their function may lead to drug addiction through pleasurable feelings, such as reward feeling evoking. In the next chapter are analysed neurotransmitters and their transporters, which are related to methamphetamine effects. Studying their structure, localization or development during life may help to bring near the drug functioning in different life periods. Methamphetamine itself and its effects are closer described in the last part of this study. The problem of methamphetamine exposed fetus is outlined there - prenatal and postnatal so far known differences, but also sex differences in methamphetamine pharma- cokinetics.

Effect of addictive drugs on prenatal development
Hofmannová, Oldřiška ; Peterka, Miroslav (advisor) ; Peterková, Renata (referee)
Substance abuse is long-term worldwide problem. This thesis summarizes findings about the effects of stimulants, opiates and hallucinogens and focuses on the most commonly used illegal representatives of individual groups: cocaine, amphetamines, heroin and LSD. All these substances have negative effect on both mother and her fetus. Some of addictive substances can influence pregnancy and childbirth. There is also higher risk of fetus mortality and morbidity of the new born baby. Prenatal exposure to addictive substances could have influence on the birth weight, length, head circumference, its further growth and behavior. Some drugs can cause neonatal abstinent syndrome which can lead without prenatal care to death of newborn.
