ANTIANXIETY PROPERTY OF TECOMA STANS LINN LEAVES EXTRACT IN EXPERIMENTAL ANIMALS - CONCLUSION

-

 

7. CONCLUSION

 

            The results obtained from these experimental models clearly confirmed that the antianxiety activity of aqueous and ethanolic extracts of Tecoma stans linn  The acute toxicity study conducted for aqueous and ethanolic extracts indicates that they are safe up to 2000mg/kg body weight.

 

            The acute treatment with aqueous extract of (800mg/kg) clearly demonstrate a dose dependant antianxiety effect comparable to standard diazepam (2mg/kg; p.o) in all experimental models of anxiety, while ethanolic extract (800mg/kg) had significant antianxiety activity comparable to standard drug diazepam (2 mg/kg; p.o) in all models.

 

            The phytoconstituents like flavonoids were reported for their antianxiety effect and these constituents were present in aqueous and ethanolic extracts of Tecoma stans linn leaves, so this active principle might be responsible for antianxiety effect. The mechanism of antianxiety activity of Tecoma stans linn leaves extracts is unclear hence further studies are needed to identify the anxiolytic mechanism(s) and the phytoconstituents responsible for the observe central effects of the aqueous and ethanolic extracts of Tecoma stans linn

MINOR DISORDERS OF NEW BORN AND ITS MANAGEMENT - NURSING ASSIGNMENT

-
INTRODUCTION         Neonatal health problems are frequently found ranging from minor physical or physiological peculiarities to the serious life threatening illnesses. Minor problems should not be ignored lightly without adequate assessment of the conditions. Early diagnosis and management of the serious problems help to overcome life long disability and to reduce neonatal morbidity and mortality. Nurses are responsible to manage the minor problems and to detect the serious problems for early and prompt management along with appropriate nursing interventions and support to the mother. MINOR DISORDERS OF NEW BORN 1. VOMITING         Vomiting is one of the common manifestations in the neonates. Regurgitation after feeds should not be confused with vomiting. Mucus vomiting often hinged with blood is quite common soon after birth. It is due to irritation often gastric mucosa by the swallowed materials during birth. Causes: ·         Dietic ·         Over feeding

KANGAROO CARE - NURSING ASSIGNMENT

-
INTRODUCTION         Caring low birth weight baby is a great challenge for the neonatal care unit and the family. Number of low birth weighs baby is still for beyond the expected target in our country. The cost of the quality management of these babies is increasing day by day. Kangaroo care is low cost approach for the care of low birth weight baby. This method of care was introduced and popularized by Dr.Edger Ray, Dr.Martinez and Dr.Charpak in late 1970s. DEFINITION         Kangaroo Mother Care (KMC) is a special way of caring low birth weight infants by skin to skin contact if promotes their health and welling by effective thermal control, breast feeding and bonding. KMC is initiated in hospital and continued at home. COMPONENTS OF KMC         In KMC, the infant is continuously kept in skin contact by the mother and breastfed exclusively to the utmost extent.         The two components of KMC are; 1.    Skin to skin contact is provi
