Abstract

The objective of this study was to determine the effect of centella leaf extract administration on decreased of the molecule cAMP responsive element modulator (CREM) expression in the testicular seminiferous tubules of male rats (Rattus norvegicus). Eight rats, aged 3.5 months with 150-250 grams of body weight (BW) were used in this study. All rats were divided randomly into four groups as if K0 as a control group whereas K1, K2, and K3 were given the centella leaf extract with doses 125, 250, and 500 mg / kg body weight respectivelly that given once daily for 30 days. At the end of the treatment, rats were sacrificed and their testes were collected and subsequently fixed in buffered neutral formalin (BNF) 10% as fixative solution for histological preparation. The CREMs expressions were detected using immunohistochemical methods. The results showed that the number of CREM expression in the seminiferous tubules significantly differ (P 0.05) between K0 and the treatment group (K1, K2, and K3). Conclusion, the administration of centella leaf extract with of the dose 125, 250, and 500 mg/kg BW can decreased CREM expression spermatids of testicular seminiferous tubules in male rat.

Abstract

This research aimed to observe and identify the development of estrogen receptor alpha (ERα) in the ovary and uterus of rats (Rattus norvegicus) at various age levels using immunohistochemistry (IHC). The ovary and uterus were collected from eight female rats aged 2, 4, 6, and 12 months and processed histologically and stained with IHC staining. This research showed, the intensity of ERα expression was found in high abundance (+++) in stroma and the corpus luteum and was weakly found (+) in the theca cells, blood vessels, oocytes and germinal epithelium of rats aged 2 months. Additionally, ERα expression in rats aged 4 months had similarities with rats aged 2 months, but the intensity of ERα had increased (++) in ovarian theca cells, blood vessels, and oocytes. In ovaries of rats aged 6 and 12 months, ERα expression had decreased (++) in the stroma and the corpus luteum and had a low expression (+) in the blood vessel and oocytes. The uterus of rats aged 2 months had low expression of ERα (+) in the stroma and luminal epithelium, moderate (++) in the myometrium, but was not found in the uterine glands. Furthermore, the expression in the uterus of rats at the age of 4 months had increased in the stroma and luminal epithelium (++) and uterine glands (+).  At the age of 6 months, it found excessively (+++) in the stroma, myometrium, and luminal epithelium, moderate expression (++) in the uterine glands.  The expression of ERα in uterus aged 12 months was almost equal to the uterus of rats aged 6 months, but the expression in the myometrium and epithelial luminal had decreased (++). It can be concluded that the development and distribution pattern of ERα in the ovaries and uterus of rats are different at each age levels, it may be related to the growth and development of reproductive organs and also closely related to the estrus cycles of rats.

Abstract

Preterm infants, born before the 37-week gestation period, have limited storage for nutrients at birth and are vulnerable to poor feeding, severe nutritional deficits and growth retardation. The immature gastrointestinal system leads preterm infants to experience a delay in initiating enteral nutrition. Inappropriate feeding can cause acute and long-term morbidity, prolonged hospitalization and increased treatment cost. Generally, preterm infants that are born after 32 weeks of gestation without severe comorbidities do not have dysphagia and should start oral feeding soon after birth. Preterm infants should have well-developed sucking-swallowing-breathing coordination by 32–34 weeks of gestational age. However, some infants take days or weeks to master the skill. The oral feeding development involves forkhead box protein 2 (FOXP2)-expressing neurons that are found in the deep layers of the cortex, basal ganglia, parts of the thalamus and Purkinje cells of the cerebellum. In mammals, these areas belong to the brain network circuits working for motor coordination in learning and acquiring sensorimotor skills. This review aimed to describe the role of FOXP2 in oral-motor skills in preterm infants, including oral feeding, sucking-swallowing-breathing coordination and language development. The oral-motor skills development could be an early predictor for language delay in premature infants, representing a vulnerable group susceptible to such delays.
