White Turmeric Rhizome Protection Effect of against Lung Tissue Damage in Copper Sulfate-Induced Wistar Rats

One of common heavy metals that pollute rivers in Indonesia is copper, which can damage various organs, including the lungs. As a potential natural herbal medicine, white turmeric rhizome has antioxidant properties that potentially protect the body from copper pollution. This study aimed to explore the potential of the white turmeric rhizome (Curcuma zedoaria) to provide a protective effect on the lungs against copper contamination. This study was an experimental study performed in June 2020 on 25 copper-induced Wistar rats which were divided into five groups: negative group that received 1 ml of copper sulfate suspension at the 12th to 14th day; positive group that received 10 mg/200 g BW of ethanol extract from white turmeric without copper sulfate suspension; and three experimental groups that received 10 mg/200 gBW, 20 mg/200 gBW, and 40 mg/200 gBW of ethanol extract from white turmeric every day, respectively, followed by copper sulfate suspension at the 12th–14th day. After 14 days, the rats were sacrificed by chloroform inhalation and the lung was excised and processed for histopathology preparation. The edema, hemorrhage, leukocyte infiltration, and alveolar septal thickness were evaluated from the lung tissue perparation. The score of tissue damage was express as median (Range) and analyzed using the Kruskal-Wallis test. The result of this study shows that there was a significant difference in lung tissue score among all groups of treatment (p-Value=0.001). The experimental group with highest dosage extract presented a good protection effect as well as the positive group. Hence, white turmeric has a good protective property for the lung against damages caused by copper contamination.

Evaluation of Ficus retusa L. Leaves with Special Reference to Antidiarrheal and Anti-spasmodic Activity.

The aim of present investigation was to evaluate the traditional claim of Ficus retusa as an anti-diarrheal and anti-spasmodic agent using different pharmacological models. Diarrhea is considered as major cause of mortality, especially in children and aged persons. Because of diarrhoea, 17% of admitted children get die. In order to treat the diarrhea, natural drugs may be useful. In order to prove the traditional claim of Ficus retusa, present work was undertaken with objective to prove antidiarrheal and antispasmodic activity. The anti-diarrhoeal activity was evaluated by magnesium sulphate induced diarrhea and 5-hydroxy tryptamine(5HT) induced diarrhea. Further, the exact were subjected to gastrointestinal motility test using standard procedure. Finding of the present study suggested that significant response was exhibited by ethanolic extract (400mg/kg bw.) of Ficus retusa. The response towards bioactivity was dose dependent. It was concluded that 400mg/kg bw of ethanolic extract is most potent in antidiarrhoeal and antispasmodic activity.

Hypoglycemic and antidiabetic effect of ethanolic extract of leaves of Annona squamosa L. in experimental animals

The ethanolic extract of Annona squamosa L. (Annonaceae) leaves was administered orally at different doses to normal as well as streptozotocin (STZ)-induced diabetic rats and alloxan-induced diabetic rabbits. The dose of 350 mg/kg body weight (bw) reduced the fasting blood glucose (FBG) level by 6.0% within 1 h, whereas, the peak blood glucose at 1 h during glucose tolerance test (GTT) was reduced by 17.1% in normal rats. The same dose of ethanolic extract reduced FBG by 26.8% and improved glucose tolerance by 38.5 and 40.6% at 1 and 2 h, respectively, during GTT in alloxan-induced diabetic rabbits. In STZ-diabetic rats, a fall of 13.0% in FBG and an improvement in glucose tolerance by 37.2 and 60.6% at 1 and 2 h, respectively, was observed during GTT. The dose of 350 mg/kg bw of ethanolic extract in 10-day treatment of a group of STZ-diabetic rats produced 73.3% fall in FBG level and no sugar was observed in fasting urine. Treatment of severely-diabetic rabbits for 15 days with a dose of 350 mg/kg of extract reduce FBG by 52.7% and urine sugar by 75%. It brought about fall in the level of total cholesterol (TC) by 49.3% with increase of 30.3% in high-density lipoprotein (HDL) and decrease of 71.9 and 28.7% in low-density lipoprotein (LDL) and triglycerides (TG) levels, respectively.
