Abstract:
The present study was designed to investigate the protective effect of
glucose, oxygen and epinephrine resuscitation on impairment in the functional role
of GABAergic, serotonergic, muscarinic receptors, PLC, BAX, SOD, CAT and
GPx expression in the brain regions of hypoxia induced neonatal rats. Also, the
role of hormones - Triiodothyronine (T3) and insulin, second messengers –
cAMP, cGMP and IP3 and transcription factors – HIF and CREB in the regulation
of neonatal hypoxia and its resuscitation methods were studied. Behavioural
studies were conducted to evaluate the motor function and cognitive deficit in one
month old control and experimental rats. The efficient and timely supplementation
of glucose plays a crucial role in correcting the molecular changes due to hypoxia,
oxygen and epinephrine. The sequence of glucose, epinephrine and oxygen
administration at the molecular level is an important aspect of the study. The
additive neuronal damage effect due to oxygen and epinephrine treatment is
another important observation. The corrective measures by initial supply of
glucose to hypoxic neonatal rats showed from the molecular study when brought
to practice will lead to healthy intellectual capacity during the later developmental
stages, which has immense clinical significance in neonatal care.
